    DESCRIPTION
    [001] The invention relates to an adapter element for receiving an HF surgical handpiece, which has at least one power connection, according to the preamble of claim 1, an HF surgical instrument with an HF surgical handpiece. HF surgical hand and an adapter element for receiving the handpiece, according to the preamble of claim 13, an adapter accessory for the interchangeable combination with an HF surgical handpiece or an adapter element, according to the preamble of the claim 17, and an assembly according to claim 23. The invention also relates to an electrosurgical system.
    [002] HF surgical devices, of the type discussed here, are basically known. When electrosurgical instruments are used, particularly when coagulating and cutting tissue with the help of high frequency current, the treated tissue heats up very quickly. Smoke is generated as a result of heating, where the smoke can include fine particles. The resulting smoke consists not only of water vapor and aerosols, but can also include carcinogenic and mutagenic components, which can be hazardous to the health of persons present in the operating room. It is therefore necessary to evacuate the smoke immediately at the place of origin during electrosurgical application to avoid excessive contamination of the environment, in particular the operating room and the people located there, to reduce the associated health hazards. Smoke evacuation systems were created for this reason, but they often deliver unsatisfactory results in terms of suction power and, in addition, compromise the ergonomics of electrosurgical instruments and even sometimes obstruct the view of the operating site.
    [003] The object of the present invention is, therefore, to create a smoke evacuation system in the form of an adapter element, an HF surgical instrument and an adapter accessory, which provide optimal suction power with minimal ergonomic weakness and eyesight.
    [004] An adapter element, with the characteristics of claim 1, is proposed to achieve the aforementioned objective. The adapter element is used to receive an HF surgical handpiece and is characterized in that it is possible to receive the handpiece in the adapter element so as to form a smoke duct in the adapter element to discharge smoke from a treatment area. .
    [005] The core of the invention is, therefore, that the smoke duct is closed only by assembling the adapter element with the handpiece and is formed by a region of the outer wall of the handpiece and a region of the inner wall. of the adapter element. Not only is the material saved in this form, but the mounting of the adapter element with the HF surgical handpiece allows for superior smoke duct suction power due to a larger smoke duct cross-section, in addition to optimal ergonomics of the resulting HF surgical instrument. Furthermore, the variably configured adapter element allows the use of a handpiece for virtually any HF surgical intervention and optimal smoke evacuation adapted to it in each case. Thus, different adapter elements, which in particular have smoke evacuators and different electrode shapes adapted to the same, can be supplied for different purposes. Therefore, the suitable instrument can be implanted for each purpose by combining the handpiece and the adapter element. Incidentally, adapter elements can be disposable products that are discarded after a single use.
    [006] Preferably at least one electrode in the form of a rod, tip, ring, sphere, loop is provided at the distal end of the adapter element. A plurality of electrodes may also be provided, in which case they may be combinations of the various types of electrodes mentioned above. To further expand the area of the adapter element, it can also be provided that, in addition, for at least one electrode there is also a fluid jet applicator which can supply a fluid, for example water for injecting or for cutting the tissue. The fluid jet applicator is preferably configured such that the distal end of the electrode has an integrated nozzle for generating a fluid jet. In this case, the electrode therefore has an integrated fluid line and thus simultaneously serves as a fluid supply line. Alternatively, a fluid supply line can also be supplied separately from the electrode. The HF surgical handpiece must then have, in addition to the power connection, a fluid connection that supplies a fluid to the fluid jet applicator.
    [007] Alternatively or additionally, if necessary, the adapter element may have means for supplying gas, in particular inert gas. As a result of this, it is also possible with the surgical instrument according to the invention to carry out the coagulation of argon plasma.
    [008] It is preferably determined that the smoke duct opens into the smoke lumen at the distal end of the adapter element. The smoke lumen is open towards a distal end of at least one electrode and is used for the admission of the resulting smoke in the vicinity of the electrode and for the passage of said smoke to the smoke duct. It is preferably determined that for the best possible smoke extraction the smoke lumen surrounds the electrode at least in certain areas, that it is possible to arrange the electrode and smoke lumen concentrically or eccentrically with respect to each other. It is particularly advantageous if the smoke lumen is adapted to the shape of at least one electrode. For example, a hemispherical, funnel-shaped or conical smoke lumen can be supplied to a spherical electrode, while a cylindrical smoke lumen, for example, can be supplied to a rod-shaped electrode.
    [009] An elongated cavity that is used not only to receive the handpiece, but furthermore also to form the smoke duct is preferably provided to receive the handpiece in the adapter element. The cavity preferably has a bearing surface, in particular in the form of at least one flap, a shell or a projection for supporting the handpiece in or on top of the adapter element. For attaching the handpiece, the adapter member preferably has a clip member, which is provided at the proximal end of the adapter member, to secure or lock the handpiece in position. In this way, the HF surgical handpiece can be attached particularly easily to the adapter element with a simple sequence of movements. It is also particularly advantageous if the adapter element is provided with a smoke detector, being possible, for example, to arrange the smoke detector in the smoke lumen or in the smoke duct. suction hose which is in turn connected to a suitable evacuation and filtration device.
    [010] In a preferred embodiment of the adapter element, at least one electrode and the smoke lumen may be part of an adapter accessory which is an interchangeable combination with the adapter element. The advantage that arises as a result is that each electrode shape always cooperates with a smoke lumen adapted to said electrode shape, such that it is possible to provide optimal suction power, advantageously, for the various electrode shapes during different applications. In that case, it is then not necessary to change the entire adapter element for different types of electrodes, but rather to replace only the adapter accessory.
    [011] An HF surgical instrument having an HF surgical handpiece and an adapter element for receiving said handpiece, in particular, according to the invention, is proposed to achieve the above-mentioned objective. The HF surgical instrument is characterized in that a region of the interior wall of the adapter element and an exterior region of the wall of the handpiece delimits a smoke duct, in the state of assembly of said plate element and said handpiece. As a result, particularly high smoke suction power is achieved when the smoke duct can be of a larger diameter, without compromising the ergonomics of the surgical instrument and obstructing the view of the operating site.
    [012] It is particularly advantageous if a (closed) seal, preferably completely peripheral, can be placed between the adapter element and the handpiece. In that case, a particularly strong seal, in particular a gas-tight seal, can be made between the adapter element and the handpiece. The handpiece preferably has at least one power connection and also, if necessary, at least one fluid connection. If either a power connection or also a fluid connection and a suitable fluid jet applicator are provided, it is possible with a single multifunctional HF surgical instrument to implement both a monopolar cutting procedure as well as a water jet application (e.g. example, tissue injection), without changing instruments. The handpiece preferably has a switching device for controlling energy and/or fluid delivery. It is particularly advantageous if an adjustment device for moving an extendable and retractable electrode is additionally provided.
    [013] An adapter accessory, with the features of claim 17, for interchangeable combination with an HF surgical handpiece with integrated smoke extraction and/or an adapter element with a smoke duct to receive an HF surgical handpiece. HF is proposed to achieve the object mentioned above, the adapter accessory that has at least one electrode and a smoke lumen.
    [014] To combine the adapter accessory with a handpiece or an adapter element, the proximal end of the adapter accessory is preferably adapted to the shape of the respective distal end of the handpiece or adapter element in such a way that a positive fit connection is formed between the two parts. Furthermore, a connecting device, for example in the form of locking recesses, a threaded connection or a magnetic connection is preferably provided, said device being arranged on the adapter fitting and being used to connect to an HF surgical handpiece. and/or an adapter member for receiving an HF surgical handpiece. In particular, the adapter elements can be disposable products that are discarded after a single use.
    [015] An adapter accessory can have at least one electrode that can be in the form of a stick, tip, ring, sphere, loop. Furthermore, combinations of a plurality of electrode types mentioned above may also be provided, at least one electrode being preferably movably supported, such that the electrode tip can therefore protrude more or less away from the Smoke lumen. .
    [016] Furthermore, the adapter accessory can be configured in such a way that it performs a dual function. Thus, in addition to the electrode, a fluid jet applicator can be provided which is configured, in particular, in such a way that the distal end of the electrode has an integrated nozzle for generating a fluid jet. In this case, it is possible to implant two different surgical applications with a single adapter accessory without changing instruments or changing the adapter accessory. For example, it is possible to coagulate or cut and inject tissue with the electrode by applying a very fine jet of water.
    [017] A set that has the characteristics, according to claim 23, is also proposed to achieve the object mentioned above. The set comprises the following components: at least one adapter fitting with at least one electrode and one smoke lumen, at least one handpiece with at least one power connection and, if necessary, with at least one fluid connection; and either at least one smoke duct integrated into or attached to the handpiece or, alternatively, an adapter member for receiving the handpiece having a smoke duct. In both alternatives, the smoke duct preferentially cooperates in the assembled state of the assembly with the smoke lumen of the adapter fitting to implement optimal smoke extraction.
    [018] Furthermore, an electrosurgery system that has an HF surgical instrument and an HF generator to which it is connected or can be combined with the HF surgical instrument is revealed and claimed. The HF surgical instrument is configured in accordance with the invention. The embodiments disclosed in this application may be developed accordingly.
    [019] The invention is explained in more detail below based on the drawing.

    [021] Figure 1 shows a perspective view of an HF 1 surgical instrument, according to the invention. The HF surgical instrument 1 comprises an adapter element 3 for receiving an HF surgical handpiece 5. The adapter element 3 is essentially elongated and, in particular, adapted to the contour of the handpiece 5, in such a way that ergonomics of the resulting HF surgical instrument is not compromised. Furthermore, the adapter element 3 has a cavity 7 for receiving the handpiece 5 and for forming the smoke duct 9 (see Figure 6b).
    [022] Provided at a proximal end 11 of the adapter element 3 is a suction hose 13, which on the one hand is in fluid communication with the cavity 7 and on the other hand is connected to an extraction device such as a pump or the like and a filter device (not shown in Figure). At its distal end 15, the adapter element 3 has, by way of example, a rod-shaped electrode 17 and a smoke lumen 19 for admitting the resulting smoke in the proximity of the electrode, the electrode 17 extending through the Smoke lumen 19.
    [023] The smoke lumen 19 is open at its distal end, that is, on the side facing the distal electrode, and thus can admit smoke during treatment. From smoke lumen 19, smoke is drawn in through smoke duct 9 and suction hose 13 and disposed in a suitable filtration system. The smoke lumen is advantageously configured in such a way that it is adapted to the shape of the electrode in each case. This situation becomes particularly evident as a result of the other Figures 2 to 5 which illustrate the adapter elements with different smoke lumens 19 and different electrodes 17, in each case the shape of the smoke lumen 19 being optimally adapted to the shape of the electrode in order to admit the resulting smoke in the proximity of the electrode as completely as possible. Thus, in Figure 2, for example, the smoke lumen 19 is configured as an elongated slit, while in Figure 3, there is a funnel-shaped or conical configuration, which widens towards the spherical electrode 17. This also applies. , correspondingly to Figure 4, where an essentially cylindrical smoke lumen 19 surrounds a rod-shaped electrode 17, at least in certain areas, and to Figure 5, where an essentially oval funnel-shaped smoke lumen 19 is assigned to a loop-shaped electrode.
    [024] The handpiece 5 comprises a switching device 21 to control the supply of energy and/or fluid to the electrode 17 of the adapter element. If the electrode 17 is designed to be able to be moved in a longitudinal direction, the handpiece 5 may additionally have an adjustment device for moving the electrode manually or electrically. Furthermore, the handpiece 5 has a power connection 23 which is connected to an HF generator to supply the electrode 17 with an HF current. If the HF surgical instrument 1 additionally has a fluid jet applicator, a fluid connection (not shown in the figure) can be provided in addition to the power connection 23.
    [025] To connect the handpiece 5 to the adapter element 3, said handpiece 5 must be inserted into the cavity 7 of said adapter element 3. In doing so, the distal end 25 of the handpiece 5 is first introduced into the cavity 7 which serves as a fulcrum for the distal end 25 of the handpiece 5 in the distal region 15 of the adapter element 3. Subsequently, the proximal end 27 of the handpiece 5 is pressed down into the cavity 7 until it the handpiece 5 cooperates with the gripping element 29 and the handpiece 5, and the handpiece 5 is therefore firmly anchored in the adapter element 3.
    [026] The gripping element 29 can, for example, be a prestressed flexible press element, which fixes the power connection 23 to the adapter element 3 by means of a suitable effort, which is exerted on the handpiece 5, which it can then be removed again from the adapter element 3. Basically, other fixing options are also conceivable for fixing the handpiece 5 to the adapter element 3. A magnetic holder, for example, is conceivable. It is essential that the handpiece 5 can be connected to the adapter element 3, in a particularly easy way, by means of a sequence of unique movements.
    [027] To connect the power connection 23 to the electrode 17, the handpiece 5 additionally has a connection 31 into which the proximal end of the electrode 17 is inserted while attaching the handpiece 5 to the adapter element 3. In this way, it is possible to establish an electrical connection between an HF generator is not shown in Figure and electrode 17. If necessary, a suitable fluid connection is additionally provided if the electrode is configured simultaneously as a water jet applicator or if a fluid supply duct that is independent of the electrode is supplied.
    [028] Overall, Figures 1 to 5 show that a handpiece 5 with adapter elements 3 configured in various ways can be combined for the widest range of applications, with just a single hand movement. It is particularly advantageous in this case that a smoke duct is created only by joining the handpiece 5 to the adapter element 3, which cooperates with a smoke lumen 19 which is adapted, in each case, to the shape of the associated electrode. In this way, a large volume of the smoke duct is created overall and therefore optimal smoke extraction is achieved.
    [029] Figure 6a shows a perspective view of the realization, according to Figure 2, while Figure 6b shows a longitudinal section through the corresponding HF surgical instrument 1, in which the handpiece 5 is thus clamped on adapter element 3.
    [030] Figure 6b makes it clear that the elongated contour of the adapter element 3 is adapted to the essentially cylindrical and also elongated configuration of the handpiece 5. The cavity 7 is essentially configured in a half-shell shape to receive the handpiece 5. To support the handpiece 5 in the cavity 7, the adapter element 3 has a bearing surface 33 on which the handpiece 5 can be supported. After inserting the handpiece 5 into the adapter element 3, the smoke duct 9 is formed by an outer wall region 35 of the handpiece 5 and an inner wall region 37 of the adapter element 3.
    [031] The handpiece 5 is held securely in the adapter element 3 by the retention region 39 at the distal end 15, which serves as a fulcrum for the distal end 25 of the handpiece 5. The proximal end 27 of the handpiece 5 by comparison is secured to the adapter element 3, using the clamping element 29 at the same time, the retention region 39 is adapted in such a way to the distal end 25 of the handpiece 5 that a positive engagement occurs when the handpiece 5 is inserted into adapter element 3. To ensure particularly easy insertion of handpiece 5 into the retention region 39, the distal end 25 of handpiece 5 is preferably tapered in design. In other words, the handpiece 5 has a smaller diameter at its distal end than in the other regions. The retention region 39 is designed to complement this and thus can easily accommodate the distal end 25 of the handpiece 5.
    [032] Figure 6b makes it even clearer that smoke arising at the operating site is sucked into smoke lumen 19 along arrow 41 and from there it is conducted further ahead of arrow 41 through smoke duct 9 between the handpiece 5 and the adapter element 3 and finally to the suction hose 13.
    [033] Finally, Figure 6b also makes it clear that the electrode 17 is held essentially centrally in a connecting piece 43 of the adapter element, in particular by means of suitable retaining ribs, and thus extends through the connecting piece. connection 43. The present smoke lumen 19 arranged in a funnel shape for admitting smoke is provided at the distal end of the connection piece 43. As also becomes clear, particularly in conjunction with Figures 4 and 5, the length of the connecting piece 43 may vary and consequently be configured differently for different application purposes. A telescopically variable length of the connecting piece 43 is also conceivable in principle.
    [034] Figure 6c additionally makes it clear that the bearing surface 33 for supporting the handpiece 5 is essentially shell-shaped in the embodiment illustrated in figures 6a to 6d, and it is not imperative that the bearing surface be formed across the entire surface along the L longitudinal direction of the HF surgical instrument. Basically, it is also conceivable to arrange a plurality of ribs arranged at a distance from each other, said ribs obstructing the flow of smoke along the arrow 41 in the smoke duct 9 as little as possible.
    [035] Figures 7a to 7d show another embodiment of the invention, in which a seal 45 is provided between the handpiece 5 and the adapter element 3, said seal which is peripherally closed and guarantees a (gas-tight) termination. of the hinge between the handpiece 5 and the adapter element 3. The handpiece 5 may have a receiving groove 47 (as shown in Figure 7a) configured according to the shape of the seal to accommodate said seal 45. However, it is also basically conceivable to provide a corresponding receiving groove in the region of the inner wall of the adapter element 3. As Figure 7d in particular makes clear in the assembled state of the handpiece 5 and the adapter element 3, the seal 45 is between the wall inner 37 of the adapter element 3 and the outer wall 35 of the handpiece 5 and, therefore, ensures the sealing of the smoke duct to the outside.
    [036] Figures 8a to 8d show yet another embodiment of an HF surgical instrument 1 in which the inner wall of the adapter element 3 has an execution step in the longitudinal direction L in which step the complementary step of the handpiece 5 is supported. In the embodiment, according to Figures 8a to 8d, the support is therefore provided in the form of bearing surfaces 33 which are configured as stages and thus allow the formation of a significantly larger cross-section of the smoke duct. extended. In this embodiment of the invention, a seal 45 is also provided, which is preferably disposable between the handpiece 5 and the adapter element 3 in the region of the bearing surface in step 33 format.
    [037] Figures 9 to 14 additionally show different examples of another embodiment of the invention, in which the connecting piece 43 is not integrally configured with the adapter element 3, but is instead combined, in the form of an accessory. adapter 49, which is interchangeable with the adapter element 3 and/or with a conventional handpiece 5, in particular with the handpiece with the integrated smoke duct or a handpiece with a smoke duct attached thereto.
    [038] Figure 9 shows a longitudinal section through an HF surgical instrument 1 with a handpiece 5 and a smoke duct 9 integrated therein which, for example, can also be configured as a hose having an opening 51 at the distal end 25 of the handpiece 5 allowing fluid communication with the adapter accessory 49. The adapter accessory 49 comprises, like the connecting piece 43 of figures 1 to 8, an electrode 17, which, for example, is held centrally or eccentrically within the adapter fitting 49, with the aid of ribs or similar fastening means, and protruding out of a smoke lumen 19.
    [039] The adapter fitting 49 is pressed onto the handpiece 5 so that the proximal end 53 engages the electrical connection 31 of the handpiece 5 in order to establish an electrical connection between an HF generator and the electrode 17. As Figure 9 shows, the proximal end of the adapter fitting 49 is adapted to the shape of the distal end 25 of the handpiece 5 such that a positive fit occurs when the two pieces are joined. Also in this case, the seal can be provided which is arranged, preferably completely peripherally, in the joining region between the handpiece 5 and the adapter accessory 49.
    [040] The attachment of the adapter accessory 49 to the handpiece 5 can be achieved by means of appropriate attachment means. In Figures 9 to 14, an example variant is illustrated, in which the adapter accessory 49 can simply be attached to the handpiece 5, by inserting the locking elements 55 provided on the handpiece 5 into the corresponding locking recesses. 57 of the adapter attachment 49. Since the locking elements 55 are flexible or spring-loaded, the adapter attachment 49 can be easily detached from the handpiece 5, for example if a different shaped electrode is required for a different surgical intervention . Alternatively, it can also be envisaged that magnetic fastening means or the like are provided on the adapter fitting 49 and on the handpiece 5 to combine the two parts.
    [041] Figures 13 and 14 show other embodiments of an adapter fitting 49 according to the invention, which are significantly longer than the examples according to Figures 9 to 12. Thus, in general, it can be seen that the 49 adapter accessory can be configured for many different applications, with different lengths, and different electrodes and different smoke lumens. Replacement is particularly easy by simply attaching the accessory to a handpiece 5. Basically, the adapter accessory 49 can also have a fluid jet applicator. This can, for example, be in the form of a nozzle integrated into the electrode or it can also be configured separately from the electrode on the adapter accessory 49. In this case, the adapter accessory 49 is to be used to carry out a fluid application (usually application of water), it is clear that the handpiece 5 may have an adequate fluid supply line and adequate control means. Incidentally, the embodiment of the invention shown in Figures 9 to 14 may also have an electrode 17 which is variable in length and thus may protrude more or less far out of the adapter fitting 49. Suitable control means, in that case, are preferably provided on the handpiece 5 in such a way that the electrode 17 can be moved manually or electrically.
    [042] The adapter accessory 49 is not only provided with an integrated smoke duct 9 for the realization of a part of the handpiece 5 shown in Figures 9 to 14, but it is also basically conceivable to combine the adapter accessory 49 with a adapter element 3, according to Figures 1 to 8 so that on the one hand the adapter element 3 can be configured for different handpieces 5 while the adapter accessory 49 is configured to be suitable for all adapter elements 3. Thus, while a standard interface may exist between the accessory adapter 49 and the adapter element 3, different adapter elements 3 may be adapted to different handpieces 5, in particular to different shapes and dimensions. A suitable HF surgical set can then, for example, have one or more adapter fittings, one or more adapter elements (adapter shell) and one or more handpieces 5.
    [043] Figure 15a shows a longitudinal section through an adapter fitting 49, while Figure 15b shows a cross section along the cut line from B to B of Figure 15a. Figures 15a and 15b make it clear that the electrode 17 can be kept inside the adapter accessory 49 with the aid of ribs 59 which, on the one hand, are in contact with the inner wall of the adapter accessory 49 and, on the other hand, form a annular opening for receiving the electrode 17. Formed between the individual ribs are openings 61 which allow smoke sucked into the smoke lumen 19 to pass through the opening 51 of the handpiece 5 and therefrom into the smoke duct 9 .
    [044] Overall, the present invention creates an advantageous smoke extraction system which, as a result of its modular design, is not only flexibly adaptable to many different HF surgical applications (in particular applications also combined using current and fluid), but which on the other hand allows for optimal suction power with minimal obstruction of ergonomics and operative site view for each individual electrosurgical application.List of Reference Numbers1 HF surgical instrument3 Adapter element5 Handpiece7 Cavity9 Smoke duct11 End proximal13 Suction hose15 Distal end17 Electrode19 Smoke lumen21 Switching device23 Power connection25 Distal end27 Proximal end29 Clamping element31 Connection33 Bearing surface35 Outer wall region37 Inner wall region 39 Retaining region41 Arrow43 Connecting piece45 Seal47 Receiving slot49 Adapter accessory51 Opening53 End proximal age55 Locking element57 Locking recess59 Rib61 OpeningL Longitudinal geometric axis
