    Description: The present invention relates to a tool holder for a surgical tool, in particular for a bur intended for milling the acetabular cavity of a patient.
    In known manner, a tool holder comprises a longitudinal drive shaft comprising:
    - a first end with first connection means allowing the application of a torque to drive the longitudinal drive shaft in rotation around the longitudinal direction,
    - a second end with second connection means for detachably receiving said surgical tool and driving it in rotation about the longitudinal direction.
    An example of a tool holder for such a cutter is described in documents EP 0 704 191 and EP 1 624 814. This tool holder with bayonet type fixing device is very complex and expensive to manufacture, due to the large number of parts it contains. This tool holder is also very complex to sterilize satisfactorily, in particular due to the movable locking lugs and their elastic means for returning to the locking position. Good sterilization thus requires at least partial disassembly of the tool holder, which takes a long time and induces a risk of loss of parts, which can render the tool holder unusable.
    Documents FR 2 960 142, US 2008/0 215 159 and DE 2 437 772 describe tool holders for surgical burs intended for milling the patient's acetabular cavity.
    None of these documents describes how the first connection means, the second connection means and the longitudinal drive shaft are manufactured. The longitudinal drive shaft is only partially shown in the figures, so that the first connection means are never shown and are never described in the description of these documents. Finally, in document US 2008/0 215 159, the second connection means have a complexity of shapes which a priori require manufacture using add-on parts manufactured separately from the longitudinal drive shaft.
    The problem proposed by the invention is to design a tool holder for a surgical tool such as a bur intended for milling the acetabular cavity of a patient, which is simple, inexpensive to manufacture and easily sterilizable.
    To achieve these and other objects, the invention provides a tool holder for a surgical tool such as a bur intended for milling the acetabular cavity of a patient, the tool holder having a longitudinal shaft d '' training including:
    - a first end with first connection means allowing the application of a torque to drive the longitudinal drive shaft in rotation around the longitudinal direction,
    - a second end with second connection means for detachably receiving said surgical tool and driving it in rotation about the longitudinal direction;
    according to the invention, the first connection means, the second connection means and the longitudinal drive shaft are formed in one piece.
    The first connection means, the second connection means and the longitudinal drive shaft thus form a whole in a single material, without being attached or attached to an independently manufactured part.
    Such a tool holder has a very small number of parts and requires little or no disassembly to be sterilized effectively.
    Advantageously, the first connection means, the second connection means and the longitudinal drive shaft can be made of metal. The tool holder is thus made of a material similar to that in which tools (milling cutters, etc.) and surgical instruments are generally made, which allows overall recycling without sorting, favoring single use.
    Alternatively, the first connection means, the second connection means, and the longitudinal drive shaft can be made of plastic. We can then choose a plastic which deforms, or even melts, at a normal sterilization temperature, which prohibits re-use and guarantees respect for single use by the user. The tool holder is thus easily recycled after a single use.
    Preferably, the second connection means can receive the surgical tool by force engagement. Such engagement is easy to achieve with second one-piece connection means, and has sufficient retention of the cutter.
    As an alternative or in addition, the second connection means can receive the surgical tool by snap-fastening. A snap is a quick, simple and intuitive mode of connection for the surgeon.
    Preferably, the second connection means can receive the surgical tool in a simple translational movement in the longitudinal direction. The relative movement to be made between the cutter and the tool holder to make the connection is very simple.
    Advantageously, the second connection means can be shaped to ensure that the surgical tool is held in a fixed orientation relative to the longitudinal direction.
    Advantageously, provision can be made for the second connection means to comprise:
    - a connection plate,
    - reception means comprising at least a first reception slot made in the connection plate and extending in a transverse direction perpendicular to the longitudinal direction.
    To simplify the configuration of the second connection means, it can be provided that:
    the reception means comprise a single reception slot,
    - The second connection means comprise retention means which are shaped to immobilize the surgical tool in rotation around the transverse direction.
    Preferably, it can be provided that:
    - said at least one receiving slot has a substantially U-shaped cross section with two opposite faces,
    the second connection means comprise retention means which comprise at least one protuberance extending from and away from at least one of the two faces of the reception slot, towards the other face and at a distance from the bottom of the receiving slot.
    To allow reception and retention in the reception slot, the protuberance can advantageously be resiliently movable away from the other face of the reception slot.
    Preferably, the elastic displacement of the protuberance away from the other face of the receiving slot is authorized by removal of material carried out behind the protuberance in the mass of the connection plate. The removal of material allows the elastic displacement of the protrusion despite the one-piece nature of the second connection means, whether the constituent material of the latter is plastic or metal.
    In another aspect, the tool holder of documents EP 0 704 191 and EP 1 624 814, due to its bayonet type fixing device, requires the application of a relative movement of translation of the tool holder relative to the cutter, then the application of a relative movement of rotation of the cutter relative to the tool holder. This forces the surgeon to hold the bur in one hand and the tool holder in the other. Holding the bur in your hand leads to a more critical risk of polluting the bur since it is intended for milling the acetabular cavity of a patient.
    To avoid forcing the surgeon to take the strawberry in his hand, the strawberry is generally arranged to bear in support means such as a substantially hemispherical cavity. The cutter generally rests against the support means according to a substantially hemispherical outer face provided with sharp teeth. To connect the tool holder to the cutter, the surgeon approaches the tool holder to the cutter in a translational movement until it comes to rest against the cutter which penetrates into the L-shaped bayonet notches of the tool holder. documents EP 0 704 191 and EP 1 624 814. To complete the bayonet-type connection, the surgeon causes the tool holder to rotate relative to the cutter until the locking pins lock the cutter on the tool holder . This rotation of the tool holder however induces a slight rotation of the cutter in the support means that the sharp teeth thus scratch or even dig. It is therefore not uncommon for material from the support means to be carried away by the bur, material which can then end up in the patient's acetabular cavity and constitute a harmful foreign body.
    Another problem proposed by the invention is therefore to devise a method of connecting a tool holder with a cutter, in particular for a cutter intended for milling the acetabular cavity of a patient, which does not require manual holding of the cutter by the surgeon and which limits the risk of scratches or even digging, of the support means in which the cutter rests before connection to the tool holder.
    To achieve these and other objects, the invention provides a method of connecting a tool holder with a cutter intended for milling the acetabular cavity of a patient; according to the invention, the method comprises the following stages:
    a) provide a milling cutter intended for milling the acetabular cavity of a patient, said milling cutter being held and supported in support means,
    b) provide a tool holder in which connection means are adapted to receive the surgical tool in a simple translational movement in a longitudinal direction,
    c) approach the tool holder of the cutter by a translational movement in the longitudinal direction until bringing the connection means in abutment against the cutter,
    d) press the cutter through the tool holder until the connection means retain the cutter.
    It is observed that this process provides a significant technical effect, regardless of the one-piece nature of the components of the tool holder. This process, as well as the tool holder specially designed for its implementation, are therefore likely to be subject to independent protection.
    Other objects, characteristics and advantages of the present invention will emerge from the following description of particular embodiments, made in relation to the attached figures, among which:

    An example of a tool holder 1 according to the invention is illustrated in FIGS. 1 and 2. The tool holder 1 is intended to carry and drive a surgical tool which is here a bur 2 intended for milling the acetabular cavity of a patient.
    The tool holder 1 comprises a longitudinal drive shaft 3 which comprises:
    a first end 4 with first connection means 5 allowing the application of a torque to drive the longitudinal drive shaft 3 in rotation about the longitudinal direction I — I,
    - A second end 6 with second connection means 7 for removably receiving the cutter 2 and driving it in rotation about the longitudinal direction l-l.
    In FIG. 1, which is a side view in section of the tool holder 1 according to the invention, it can be seen that the first connection means 5, the second connection means 7 and the longitudinal drive shaft 3 are formed from one piece.
    The tool holder 1 also includes a gripping sleeve 8 which is mounted so as to be able to rotate on the longitudinal drive shaft 3. When the driving means apply a rotational coupling on the longitudinal drive shaft 3 via the first connection means 5, the surgeon holds and directs the tool holder 1 while holding the gripping sleeve 8 in his hand. The gripping sleeve 8 may consist of a tube provided with a slot over its entire length. The slot in the gripping sleeve 8 allows it to be snapped onto the longitudinal drive shaft 3.
    The first connection means 5, the second connection means 7 and the longitudinal drive shaft 3 are made of plastic. The manufacturing cost of these elements is thus very reduced, which favors a single use by the surgeon.
    Single use can in particular be guaranteed by choosing a plastic such as POM (polyoxymethylene) or a polyamide which deforms, or even melts, at a normal sterilization temperature which is generally between approximately 120 ° C. and approximately 140 °. C in an autoclave.
    After use, the tool holder 1 can be recycled in a very simple and inexpensive manner.
    Alternatively, we can opt for a metal fabrication.
    The second connection means 7 are shaped to maintain the fixed orientation of the cutter 2 relative to the longitudinal direction l-l.
    In this case, the tool holder 1 of Figs. 1 and 2 comprises second connection means 7 which receive the cutter 2 by snap-fastening. To do this, the second connection means 7 comprise a connection plate 9 and reception means 10 comprising at least a first reception slot 11 formed in the connection plate 9. The first reception slot 11 extends in a transverse direction ll-ll perpendicular to the longitudinal direction ll.
    The first receiving slot 11 has a substantially U-shaped cross section with two opposite faces 11a and 11b. The second connection means 7 comprise retention means 12 which include protuberances 12a and 12b. The protrusion 12a extends from and away from the face 11a towards the face 11b, while the protuberance 12b extends from and away from the face 11b towards the face 11a. The two protrusions 12a and 12b are located at a distance from the bottom 32 of the first receiving slot 11. The second connection means 7 of the tool holder
    I of fig. 1 and 2 are better visible in fig. 5.
    In this fig. 5, there is the first reception slot 11 and the retention means 12. The reception means 10 comprise a second reception slot 13 formed in the connection plate 9. This second reception slot 13 is oriented in a transverse direction III -lll perpendicular to the longitudinal direction ll and intersecting (in this case perpendicular) with the transverse direction ll-ll. There are thus receiving means 10 in cross adapted to receive and retain the cutter 2 illustrated in FIG. 3. The cutter 2 is substantially in the form of a cup 14 with a convex outer surface 33 substantially hemispherical provided with a plurality of sharpened teeth 15. To ensure its attachment to a tool holder 1, the cutter 2 has a fastening structure 16 with four radial arms 16a to 16d arranged in a cross, extending from the annular edge of the cup 14 and joining at its center. In practice, two branches 16a and 16c or 16b and 16d are received and retained in the first reception slot 11 while the other two branches 16a and 16c or 16b and 16d are received in the second reception slot 13.
    The second receiving slot 13 has a substantially U-shaped cross section but is devoid of retention means 12. The second receiving slot 13 thus only receives two of the arms 16a to 16d in support to prevent rotation of the cutter 2 around the transverse direction ll-ll in order to keep it in a fixed orientation relative to the longitudinal direction ll. In addition, the second reception slot 13 can also be retentive like the first reception slot 11.
    The second connection means 7 being formed in one piece, the retention carried out by the protrusions 12a and 12b can be done by deformation or compression of the material of the protrusions 12a and 12b.
    In the embodiment illustrated in FIGS. 1, 2, 4 and 5, the protrusions 12a and 12b are resiliently displaceable. The protrusion 12a is resiliently displaceable away from the face 11b of the first receiving slot
    II while the protrusion 12b is resiliently displaceable away from the face 11a of the first receiving slot
    11. In order to make possible and / or promote this elastic displacement, provision has been made for removing material 17a and 17b behind the protuberances 12a and 12b in the mass of the connection plate 9.
    In FIG. 5, the material removals 17a and 17b are produced by means of two transverse bores perpendicular to the longitudinal direction l-l and parallel to the transverse direction ll-ll. The material removals 17a and 17b are in the form of two holes made over at least part of the length of the protrusions 12a and 12b in the transverse direction ll-ll.
    The material 17a and 17b can be removed in different ways, as illustrated in FIGS. 6 and 7. In fig. 6, the material removals 17a and 17b, also carried out behind the protrusions 12a and 12b in the mass of the connection plate 9, are in the form of longitudinal bores extending parallel to the longitudinal direction l-l. In fig. 7, the material removals 17a and 17b are in the form of slots 18 and 19 extending parallel to the transverse direction ll-ll and perpendicular to the longitudinal direction l-l. Two elastically displaceable tongues 20 and 21 are thus obtained.
    The three variants of second connection means 7 illustrated in FIGS. 5 to 7 are all suitable for receiving and retaining the cutter 2 illustrated in FIG. 3. These are also suitable for receiving and retaining the cutter 2 illustrated in FIG. 8 which has two branches 16a and 16c extending in a diametrical direction IV-IV from the center of the cup 14 to the annular edge of the cup 14. The branches 16a and 16c extend from the center of the cup 14 to 'at the annular edge of the cup 14 while the branches 16b and 16d extend from the center of the cup 14 in a diametrical direction VV but do not extend to the annular edge of the cup 14.
    The second connection means 7 can be configured in a still different way as illustrated in FIGS. 9 and 10. In these figures, the reception means 10 comprise a retentive reception slot 22 shaped substantially identical to the first reception slot 11 illustrated in FIGS. 5 to 7. In this case, the receiving slot 22 has a substantially U-shaped cross section with two opposite faces 22a and 22b. The reception slot 22 is made retentive by retention means 12 which comprise a protuberance 23a extending from and away from the face 22a towards the face 22b, and a protuberance 23b extending from and away from the face from face 22b to face 22a.
    A material removal 24 is performed behind the protrusion 23a so as to allow an elastic displacement of the latter away from the face 22b of the receiving slot 22. A material removal behind the protrusion 23b is also possible as an alternative or in addition.
    The connection plate 9 also has two lateral flats 25 and 26.
    The second connection means 7 illustrated in FIGS. 9 and 10 are intended to receive and retain the cutter 2 illustrated in FIG. 11 which has a fixing structure 16 in H. The central branch 27 of the H is intended to be received and retained in the receiving slot 22 while the lateral branches 28 and 29 of the H are intended to come to bear in the lateral flats 25 and 26.
    The use of a tool holder 1 according to the invention will now be described by means of FIGS. 1 and 4 for the connection of a tool holder 1 to second connection means 7 such as those illustrated in FIG. 5 to receive and retain a cutter 2 as illustrated in FIG. 3.
    The tool holder 1 is initially contained in the sterile state in a closed antimicrobial envelope. The strawberry 2 is also initially placed in a sterile manner in an antimicrobial envelope.
    The surgeon opens the envelope of the cutter 2 and arranges it in support means 30 comprising a substantially hemispherical concave receiving face 31. The cutter 2 rests in the support means 30 in abutment along its teeth 15 against the receiving face 31.
    The surgeon then opens the sterile envelope of the tool holder 1 to take the latter, and directs it substantially as illustrated in FIG. 1 with the reception slots 11 and 13 situated respectively in correspondence of the branches 16a to 16d. The longitudinal direction l-l is substantially perpendicular to the plane P in which the branches 16a to 16d extend. The plane P is also the substantially equatorial plane of the cup 14. The surgeon then approaches the tool holder 1 of the cutter 2 by a translational movement illustrated by the arrow T, in the longitudinal direction ll, until bringing the second connection means 7 bearing against the cutter 2. The surgeon then continues the translation by pressing on the cutter 2 via the tool holder 1 until the second connection means 7 retain the cutter 2 by snap-fastening.
    In practice, during this last step, the bearing force exerted by the surgeon causes an elastic displacement of the protrusions 12a and 12b to allow the penetration of the branches 16a and 16c in the first receiving slot 11. The second means connection 7 thus receive the cutter 2 by snap-fastening. Alternatively, the second connection means 7 can receive the cutter 2 by force engagement in the first receiving slot 11 by means of a first receiving slot 11 of width slightly less than the transverse width of the branches 16a and 16c.
    In all cases, the second connection means 7 receive the cutter 2 in a pure translational movement T in the longitudinal direction l-l. The connection of the cutter 2 to the tool holder 1 thus requires no relative rotational movement between the tool holder 1 and the cutter 2, which avoids deterioration of the concave receiving face 31 of the support means 30 by the teeth 15 of the strawberry 2.
    At the end of this connection process, the tool holder 1 and the cutter 2 are integral and are presented as in FIG. 4.
    To maintain the fixed orientation of the cutter 2 relative to the longitudinal direction ll, the second connection means 7 may comprise, in another variant, a single receiving slot extending in a transverse direction perpendicular to the longitudinal direction ll. The second connection means 7 then comprise retention means which are shaped to immobilize the cutter 2 in rotation about the transverse direction along which extends the single receiving slot. In practice, a single receiving slot may be provided with a non-circular cross section. For its part, the cutter 2 has a fixing structure 16 with a single branch (for example diametral) with a non-circular cross section and complementary to the cross section of the single receiving slot.
    The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below.
