    专利说明:

    The present invention relates to an apparatus for disinfecting medical instruments, advantageously those carrying at least one movable tool, said tool being mounted at the free end of a hollow lance, while the other end of this lance is installed in a drive housing, with a Tray for holding a disinfecting fluid, in which the instruments to be cleaned can be inserted.
    It is known that objects, such as surgical instruments adhere to what remains of human tissue or the like. Have to be cleaned and disinfected before further use thereof. It is also known that such objects or instruments placed in a basket-like structure and then brought into a cleansing and sterilizing liquid. As long as such items are made of a single piece of material, such a cleaning type is usually sufficient.
    However, if an object consists of several parts, which are even connected in a movable manner, for example by means of joints, then it is hardly possible to achieve the required degree of sterility of such instruments in the said conventional manner. This is because the tissue remnants in the gaps, e.g. of the joints, and because it is difficult to bring out these remnants of tissue by merely "boiling" the instruments out of the gaps.
    Another problem is the current lack of hospital staff. The hospital staff are also only human and so it may happen because of the current time pressure that the instruments are not sufficiently cleaned and disinfected. Even in a single case, this can have serious negative health consequences for the next patient. Therefore, there is a desire that the disinfection of the hospital instruments as far as possible, is carried out automatically. For the automated disinfection of the instruments, the subjective influence of the operating personnel is largely excluded.
    The object of the present invention is to eliminate these and other disadvantages. This object is achieved according to the invention with the aid of the apparatus of the type mentioned above, as defined in the characterizing part of claim 1.
    Hereinafter, embodiments of the present invention will be explained in more detail with reference to the accompanying drawings. It shows:<Tb> FIG. 1 <SEP> in a front view an overall view of the present apparatus,<Tb> FIG. 2 <SEP> in a plan view the apparatus of Fig. 1, which is equipped with a trough for receiving the surgical instruments to be cleaned,<Tb> FIG. 3 <SEP> in a side view an instrument carrier which has two opposite sections of the present apparatus for receiving the instruments to be cleaned,<Tb> FIG. 4 <SEP> in a plan view the instrument carrier of FIG. 3 with four surgical instruments to be cleaned,<Tb> FIG. 5 <SEP> enlarges a section of FIG. 4,<Tb> FIG. 6 <SEP> in perspective a compilation of some of the mechanical components of the facilities, or instrument carrier for receiving the instruments to be cleaned, and<Tb> FIG. 7 <SEP> enlarges a section from FIG. 6 in a vertical section.
    Fig. 1 shows in a front view an overall view of the present apparatus. The present apparatus for disinfecting objects 2, in particular medical instruments, which may have movable components, has an overall housing 1, which is substantially cuboid. (FIGS. 1 and 2) This housing 1 has a top wall 101, a front wall 102, a rear wall 103, side walls 104 and 105, and a bottom 106. On the top wall 101 is a known display device 107, which may be combined with a keyboard, or touch panel or other input means.
    In the top wall 101 of the overall housing 1, a trough 108 is embedded. This trough 108 is intended, inter alia, for receiving a disinfecting fluid and for receiving the instruments 2 to be disinfected. The tub 108 has a front wall 109, a rear wall 110, two side walls 111 and 112, a tub bottom 113, and a lid (not shown).
    The present apparatus further comprises means 5 for handling at least one of the instruments 2 to be disinfected (FIGS. 3 to 4). These handling means 5 comprise an open-topped cage-like body of mutually rigidly connected rods 6. These rods 6 form a front wall 51, a rear wall 52, side walls 53 and 54 and a bottom 55 of the cage 5. The walls 51 to 55 of this cage 5 are as a grid made of said rods 6. It is important that the disinfecting fluid has the most unhindered access to the instruments 5 located in the cage 5 to be cleaned. The dimensions of this cage device 5 are chosen so that this device 5 can find space in the tub 108. The instruments to be disinfected 2 are first placed in this handling basket 5 and lowered with this in the tub 108.
    The instruments 2, which can be disinfected by the present apparatus, are expediently components of surgical equipment. Such articles 2 (Figures 3, 4 and 5) have a drive housing 30 from which a hollow lance 31 extends. The drive housing 30 is basically cuboid. Elongated actuating pieces (not shown) pass through the lance 31. The first ends of these actuating pieces lie inside the drive housing 30. The opposite or second ends of the actuating pieces are located in the region of the free end portion of the hollow lance 31. An operating tool 32, such as scissors, pliers, clamping pieces, sewing tools, needle, microcameras , etc., stands out from the free end of the lance 31.
    The second ends of the actuating pieces in the hollow lance 31 are coupled via joints (not shown) with the surgical tool 32 at the free end of the lance 31. To the cavity in the lance 31 and as a continuation of this one or more channels 33 are connected inside the drive housing 30. One end of the channel 33 opens into the cavity in the lance 31. The other mouth 35 of this channel 33 lies in the lance 31 opposite side wall 34 of the drive housing 30. The present apparatus is designed so that at least the interior of the hollow lance 31 and / or the surgical tool 32 of the instrument 2 can be disinfected.
    The present apparatus comprises a plurality of devices, each of which may contribute to the disinfection of the instruments 2 in a different way. This includes, among other things, a source 10 of oscillations (FIG. 2) which comprises piezoelectric transducers 11. These transducers 11 are vibrationally coupled to the walls of the tub 108, such that the vibrations generated by these transducers 11 pass into the interior of the tub 108 and then up to the objects 2 to be disinfected, where they have a cleaning and disinfecting effect. The transducers 11 are connected to at least one generator of vibrations (not shown). This generator can generate multi-frequency vibrations in the range of ultrasound.
    Instrument holding sections 15 and 16 (Figures 3, 4 and 5) represent further components of the present apparatus which allow the instruments 2 to be cleaned in the apparatus and simultaneously disinfected. The instrument holding sections 15 and 16 are located in the basket-like means 5. Each one of these instrument holding sections 15 and 16 is arranged in the region of one of the opposite side walls 53 and 54 of the basket 5. The respective instrument holding section 15 or 16 has a device 17 for distributing the disinfecting fluid within the instrument holding section 15 or 16 and a device 18 for receiving at least one of the instruments to be disinfected 2. The distributor 17 and the receiving device 18 are assigned to each other, that they form a functional group within the respective instrument holding section 15 or 16.
    The main body 23 of the distribution device 17 (Figures 5 and 6) is designed as an elongate block of material with a quadrangular cross-section in which channels are designed for distributing the disinfecting fluid. From the main body 23 is a piece of pipe 24, through which the disinfecting fluid in horizontally extending channels 8 and 9 (Fig. 3 and 5) of the base body 23 of this distribution device 17 can be performed. The entry parts of these horizontally extending channels 8 and 9 meet in the interior of the material block 23 with the outlet mouth (not shown) of the pipe section 24 for the supply of the disinfecting fluid. A first set of nozzles 25 is installed in one of the horizontally extending sides 22 and 26 of the base body 23 of the distributor 17. The entry parts of these nozzles 25 are fluidly connected to the horizontal channels 8 and 9 in the interior of the main body 23 and thus also to the supply line 24 of the disinfecting fluid (not shown). The outlet openings 27 of these nozzles 25 of the first set open into the interior of the basket 5 and they produce a jet of disinfecting fluid, which is directed vertically.
    A second set of nozzles 28 (FIG. 6) is installed in that side wall 29 of the base body 23 of the distributor device 17, which faces the receiving device 18 (FIG. 5) for the instruments 2. The inlet parts of these second nozzles 28 are also connected via the horizontally extending channels 8 and 9 in the interior of the main body 23 of the distributor 17 to the fluid supply line 24 (not shown). The longitudinal axis of the channels in these second nozzles 28 is oriented so that these second nozzles 28 produce a jet of disinfecting fluid which is directed horizontally.
    The base body 40 (Fig. 5) of the receiving device 18 for the instruments 2 is also designed as an elongate block of material with a quadrangular cross-section, are present in the channels. Beds 41 (FIG. 4) for receiving the drive housing 30 of the instruments 2 are made in the top wall 42 of the material block 40. The drive housing 30 of one of the instruments 2 can be inserted laterally into one of these beds 41. Thereafter, one of the horizontal nozzles 28 of the second set on the main body 23 of the distributor 17 in the mouth 35 of the channel 33 in the drive housing 30, which is located in the rear wall 34 of the drive housing 30, d. H. facing the distributor 17. The fluid jet passes from the second nozzle 28 through the channel 33 in the receiving housing 30 and enters the cavity in the lance 31, to the end of the lance 31 of the instrument carrying the tool 32 and from there back to the channel 33 in the receiving housing 30th
    Cavities are executed in the material block 40 of the receiving device 18. The cavities of a first group thereof are used to accommodate devices which provide the drive of the components of the respective cleaned instruments 2. Because these components must be moved during the disinfection process, so that unwanted particles from the columns in the instrument 2 can be removed. The cavities of a second group serve to receive a device 60 for locking the instruments 2 when they are in the respective bed 41 of the receiving device 18.
    The locking device 60 (Figures 6 and 7) includes locking pins 61. The longitudinal axis of these locking pins 61 extends vertically. The respective locking pin 61 is mounted in a recess 62 which is executed in the material block 40 of the receiving device 18 from above and in the region of the respective bed 41 for receiving the drive housing 30 of the instruments 2. The lower end of the respective locking pin 61 is provided with a flat head 63. Above this head 63, a stop 64 is formed on the inner wall of the recess 62 in the material block 40. Between this stop 64 and the head 63 of the locking pin 61 is a compression spring 65 which pushes the pin 61 downwards. The overhead portion of the bolt of the high-speed locking pin 61 can engage in a recess 66 which is executed in the bottom of the drive housing 30 from below. The locking pin 61 prevents the drive housing 30 from slipping out of the bed 41 during the disinfection of the instrument 2.
    The locking device 60 further comprises a rod 67 for the actuation of the locking pins 61. This actuating rod 67 is located below the locking pins 61 and it is perpendicular to the longitudinal direction of the locking pins 61, d. H. horizontally movable. In the operating rod 67 constrictions 68 are performed in the region of the respective locking pin 61. The flanks 69 of these constrictions 68 are inclined and flat. In Fig. 7, the receiving housing 30 of the instruments 2 are not locked in their beds 41 yet. This is because the heads 63 of the locking pins 61 rest approximately in the middle of the interior of the constrictions 68 of the operating rod 67. The actuating rod 67 protrudes laterally, in the case shown, it is on the right (Fig. 5) out of the block of material 18, where this projecting end of this rod 67 is provided with a handle 43. As you pull on this handle 43, the actuating rod 67 moves to the right. The heads 63 of the locking pins 61 slide along one of the oblique flanks 69 of the constriction 68. As a result, the locking pin 61 is pushed upwards. The upper section, d. H. the bolt of the locking pin 61 in the bore 66 in the bottom of the drive housing 30 and the position of the instrument 2 in the bed 41 is thereby locked.
    Figures 3, 4 and 5 show an embodiment of the present apparatus with which several instruments 2 can be disinfected simultaneously. In the handling carrier 5 are the two already discussed instrument holding sections 15 and 16 of the apparatus. Each of these instrument holding sections 15 and 16 is associated with one of the side walls 53 and 54 of the handling carrier 5. (Fig. 3) The instrument holding portions 15 and 16 are located in the basket 5 at different heights. The first instrument holding section 15 is located above the second instrument holding section 16 (FIG. 3). The instruments 2 form two layers 20 and 21, which lie one above the other. In the case illustrated, the respective layer 20 or 21 comprises four instruments 2 lying next to one another (FIG. 4).
    The instruments 2 of the respective layer 20 and 21 are oriented opposite to each other. This means that the housing 30 of the instruments 2 of a layer 20 to the right side wall 54 and the housing 30 of the instruments 2 of the second layer 21 to the left side wall 53 are arranged closer. The drive housings 30 of the instruments 2 of the first layer 20 are seated in the beds 41 of the first and upper instrument holding sections 15. The drive housings 30 of the instruments 2 of the second layer 21 thereof are seated in the beds 41 of the second and lower instrument holding sections 16, respectively closer to the first left side wall 53 of the handling carrier 5. It follows that the lances 31 of the overhead instruments 2 are above the drive housing 30 of the second layer 21 of the instruments 2. Accordingly, the lances 31 of the instruments 2 of the second layer 21 are below the drive housings 30 of the first layer 20 of the instruments 2.
    The mouths of the first, vertically directed nozzles 25, which are located on the upper and lower horizontal side 22 and 26 of the material block 23 of the distributor 17 are against the underlying and overlying lances 31 of the instruments 2 of the other Group 20 or 21 directed. The effluent from these vertical nozzles 25 fluid supports the disinfection of the tools 32 and the outer surfaces of the instruments 2 of the other layer 20 and 21 of the instruments. 2
    In Fig. 4 it is indicated that in the bottom of the drive housing 30 of the instruments 2 wheels 70 are for driving movable components of the instruments 2, which are located both within the lance 31 and at the free end of the lance 31 of the instrument 2 , There are usually four such wheels 70 in a drive housing 30. One of each is located in one of the corners of the drive housing 30 having a substantially quadrangular outline. To ensure the movement of the movable components of the instrument 2, however, it is sufficient if only one of these wheels 70 is driven. For this purpose, there is a transmission wheel 71 (FIG. 6) in the respective recording bed 41 for each of the instruments 2. This transmission wheel 71 engages the drive wheel 70 in the housing 30 of the instrument 2 after the housing 30 is inserted into the recording bed 41 has been.
    The main body of the transmission gear 71 has an upper disk-shaped portion 72, the free end face is free in the plane of the bottom of the receiving bed 41. Approximately star-shaped slot-shaped openings 73 are formed in the end face of this upper portion 72 of the transmission wheel 71. Cams (not shown) protrude downwardly from the free end face of the drive wheel 70 in the drive housing 30 of the instrument 2. These cams can engage in the slot-shaped openings 73 in the upper end face of the transmission gear 71.
    The main body of the switching wheel 71 further includes a second, lower portion 74. This second portion 74 is located below the upper disk-shaped portion 72 of the transmission wheel 71 and is coaxially arranged with respect to this upper disk portion 72. The circumferential surface of this lower and second wheel portion 74 is provided with teeth. The switching wheel 71 is embedded in the material block 40 of the receiving device 18 so that the toothed portion 74 of the switching wheel 71 is located inside the material block 40 of the receiving device 18.
    An element 75 for driving the Vermittlungsrades 71 is provided. This drive element 75 has a main body whose longitudinal section is substantially T-shaped. The stem 76 of this drive element 75 lies within the material block 40 next to the transmission wheel 71 (FIG. 6), the axis of rotation of the transmission wheel 71 being practically perpendicular to the longitudinal axis of the drive element 75. The stem 76 of the drive member 75 has a thicker portion 78 and a thinner portion 79. Between these two portions 78 and 79 is a circumferential shoulder 80 on the stem 76. One of the side surfaces of the thicker stem portion 78 is provided with a straight serration 81 (FIG. Fig. 6). These teeth 81 are designed and arranged so that they can mesh with the teeth on the underlying disc 74 of the transmission wheel 71. The head 77 of the drive element 75 adjoins the free end of the thicker stem portion 78 and it is integral with this stem portion 76.
    In the material block 40 (FIG. 5) of the receiving device 18, an elongated cavity 44 is executed, whose longitudinal section is also substantially T-shaped, wherein the longitudinal axis 45 of this cavity 44 extends horizontally. The inner shape of this cavity 44 has sections of different diameters. The dimensions of the individual sections of the cavity 44 are selected so that said drive element 75 can not only be located in this cavity 44, but can also be displaced in this cavity 44 in the longitudinal direction of the stem 76 thereof.
    The widest portion 47 of the cavity 44 in the material block 40 of the receiving device 18 abuts that wall 46 of the material block 19 of the distribution device 17 for the fluid, which faces the receiving device 18. In this wall 46 of the distributor 17 are outlet openings 82 and 83 of the horizontal channels 8 and 9 in the material block 19 of the distributor 17. By the second or lower of these outlet openings 83, the disinfecting fluid from the interior of the lower horizontal channel 9 in the distribution device 17th get into the adjacent cavities 44 in the material block 40 of the receiving device 18. These cavities 44 are assigned to the instruments 2 of the second or lower layer 21.
    By contrast, the disinfectant fluid from the upper horizontal channel 8 passes through the first outlet openings 82 into the first, or horizontally directed, outer nozzles 28. Through the openings 35 in the rear wall 34 of the drive housing 30 and through the horizontally directed nozzles 28 passes pulsating disinfecting fluid in the longitudinal channel 33 in the respective drive housing 30 and then to the movable components of the instrument 2. The second or vertically directed nozzles 25 are in the case shown in Fig. 5, however, connected to the cavity of the second horizontal channel 9.
    The widest portion of the cavity 44 in the material block 40 serves to receive the head 77 of the drive element 75 with the T-shaped longitudinal section. This widest portion of the cavity 44 is designed so that the T-head 77 can move in this widest region of the cavity 44 as the piston in a cylinder. In Fig. 6, the piston 77 is shown angularly. It is understood that this piston 77 may also have a circular cross-section.
    In the opposite end portion of the elongated cavity 44 is the narrowest portion 48 of this hollow space 44. In this, the thinnest portion 79 of the stem 76 of the drive member 75 can move longitudinally. In the inner wall of this narrowest portion 48 of the cavity 44, a circumferential shoulder 84 is executed. Between this shoulder 84 and the circumferential shoulder 80 on the drive element 75 is a compression spring 56 (FIG. 6) which pushes the piston 77 to the right.
    The pipe section 24 is a valve (not shown) upstream, which is interposed in the supply line of the disinfecting fluid. This valve can be opened and closed periodically. In the supply line in front of this valve, the disinfecting fluid is under pressure. When the valve is opened, a surge of disinfectant fluid enters the cavities 8 and 9 in the distributor 17. Such bumps of disinfecting fluid penetrate through the outlet openings 82 and 83 of the horizontal channels 8 and 9, which are formed in the wall 46 of the distributor device 17, inter alia even into the cavity 44 in the receiving device 18. Such fluid bursts act on the end face of the piston 77 in the cavity 44 and they force the piston 77 and thus also the entire drive element 75 to move to the left. After the control valve in the fluid supply line has been closed, the pressure within the distributor device 17 as well as inside the cavity 44 is reduced. Now, the compression spring 56 on the stem 76 can move the de-pressurized drive member 75 to the right. This play of the left and right-hand movements of the drive member 75 is repeated at each opening and closing of the control valve.
    As will be remembered, the thicker portion 78 of the stem 76 carries the teeth 81 which mesh with the teeth on the indexing wheel 71. Thus, the here and forth going movement of the drive element 75 transmits to the switching wheel 71, which rotates about its axis of rotation back and forth. The depending projections on the underside of the drive wheel 70 in the housing 30 of the respective instrument 2 are engaged via the slots 73 in the transmission wheel 71 in the receiving device 18 in engagement. This coupling causes the drive wheel 70 in the instrument housing 30 performs the same pivotal movements as the switching wheel 71.
    As stated, the moving parts in the interior of the lance 31 and the components of the tool 32 are coupled to the drive wheel 70, so that the pressure surges of the disinfecting fluid in the distributor 17 cause the disinfecting movements of the moving parts of the instrument 2. The jets of the disinfecting fluid exiting the nozzles 25 and 28 are also subject to said fluctuations in pressure in the disinfecting fluid. Such blasting of the outer surfaces of the lances 31 and the tools 32 with the disinfectant causes intensive disinfection of the outer surfaces of these components of the instruments 2. It should be noted that the movements of the components of the disinfected instruments are caused solely by the control of the inflow of the disinfecting fluid and therefore no electric motor or the like. Need.
    In the present apparatus advantageously the surgical instruments of the system da Vinci can be disinfected.
    The apparatus also comprises a device by means of which the trough 108 can be filled with a sterilizing medium. There is also provided a device which allows a metered delivery of the disinfecting fluid into the tub 108. Furthermore, means are provided which allow the discharge of the spent disinfecting fluid from the tub 108 Finally, a device is provided which allows the flushing of the inner walls of the tub 108 and located in the tub 108 instruments 2.
