Description

The present invention relates to an assembly for implanting an acetabulum into a cavity of an iliac bone of a patient. When placing a hip prosthesis, most often, the practitioner implants an acetabulum in a cavity of the patient's pelvic bone and implants a prosthetic rod in the patient's femur. The acetabulum and the femoral head of the prosthetic stem allow reconstruction of the hip joint. To implant an acetabulum, the practitioner begins by preparing the cavity of the pelvic bone, for example using a specific bur. Thereafter, the practitioner must seize the acetabulum and introduce it into the prepared cavity. Practitioner's grasping of the acetabulum may be difficult and the acetabulum may elude the practitioner and come into contact with non-sterile items. In addition, the acetabulum must be impacted in force in the cavity of the pelvic bone, to remain fixed there. This operation can not be done by hand and requires the use of specific tools to impact the acetabulum. It is specified that the tools allowing the impaction of an acetabulum are called ancillaries. It is therefore necessary for the practitioner to use an ancillary device adapted to grip and impact the acetabulum in the cavity of the pelvic bone. It is known, from patents FR 2,994,645, FR 2,948,013, FR 2,785,523, to use an ancillary which comprises means for gripping an acetabulum. The gripping means of the ancillary device described in this document, use stops to exert a radial pressure inside the acetabulum. In addition, these gripping means also have an axial abutment for exerting a force on the acetabulum during the impaction. It is specified that in this document, by "axial" it should be understood substantially parallel to the axis of revolution, and by "radial" it should be understood substantially perpendicular to the axis of revolution. After impaction of the acetabulum, the practitioner must separate the acetabulum from the ancillary. For this purpose, the practitioner must exert traction on the ancillary to dissociate the acetabulum. The traction thus exerted is contrary to the direction of impaction of the acetabulum and may, in some cases, displace the acetabulum into the cavity of the iliac bone.

In this technical context, an object of the present invention is to provide a set for the implantation of an acetabulum for separating an acetabulum from an ancillary without risk that the acetabulum moves in the cavity of the iliac bone. According to a general definition, the invention relates to an assembly for the implantation of an acetabulum, comprising: an acetabulum adapted to be implanted in a cavity of a patient's pelvic bone, a gripper which comprises reversible retaining members of the acetabulum and which comprises means for receiving an ancillary device, an ancillary device which comprises gripper attachment means configured to cooperate with the receiving means of the gripper. The assembly comprises means for ejecting the acetabulum by the gripper adapted to exert a thrust on the acetabulum so as to disengage the acetabulum from the reversible retaining members. Insofar as the ejection of the acetabulum is effected by a thrust on the acetabulum and not by a traction, the risks of a modification of the implantation position of the acetabulum in the pelvic bone are reduced. Thus, the invention provides an assembly for the implantation of an acetabulum 20 for separating an acetabulum from an ancillary device by making it possible to maintain the implantation of the acetabulum in the cavity of the iliac bone. The means for ejecting the acetabulum by the gripper may comprise at least one thrust member mounted on the gripper and actuating members of the thrust member mounted on the ancillary. In addition, said at least one pushing member can be slidably mounted on the gripper and actuated by the actuating members between an acetabular retention position and an ejection position in which the at least one push member push the acetabulum. Said at least one thrust member may comprise at least one rod 30 configured to slide relative to the gripper. The actuating members may comprise at least one pin mounted on the ancillary slidably and adapted to actuate said at least one thrust member. According to one embodiment, the actuating members may comprise a rod connected to a maneuverable handle, so that the rod can slide said at least one pin relative to the ancillary.

The receiving means provided on the gripper may have at least one fingerprint configured to receive a nipple ancillary form complementary to that of the footprint. In addition, said at least one impression may have at least one notch adapted to receive a portion of a radially expandable elastic rod assembled around the nipple of the ancillary. In addition, said at least one pin has at least one flat part arranged to receive the elastic ring in a retracted position, the displacement of the pin causing the elastic rod to exit the flat and the expansion of the elastic ring. Advantageously, the expansion of the elastic ring makes it possible to lock the attachment of the ancillary to the gripper during the ejection of the acetabulum. The retaining means of the gripper may have at least one lug configured to be snapped into a notch of the acetabulum. The thrust member may be arranged to exert a thrust of the acetabulum substantially along the axis of revolution of the acetabulum. Thus, the thrust exerted by the thrust member is collinear with the direction of implantation of the acetabulum in the cavity of the pelvic bone. Other features and advantages of the invention will become apparent from the description which follows, with reference to the accompanying drawings which show an embodiment of the invention. - Figure 1 is a perspective view, in section, of the assembly according to the invention; - Figure 2 is a front view, in section, of the assembly according to the invention; FIG. 3 is a front view, in section, of the assembly according to the invention during the ejection of the acetabulum; - Figure 4 is a front view, in partial section of the assembly according to the invention during the coupling of the ancillary to the gripper; - Figure 5 is a front view, in partial section of the assembly according to the invention when the ancillary is coupled to the gripper; - Figure 6 is a front view, in partial section of the assembly according to the invention during the ejection of the acetabulum; - Figure 7 is a front view, in partial section of the assembly according to the invention when the acetabulum is separated from the gripper.

As can be seen in Figures 4 to 7, the impression 36 is substantially centered with respect to the axis A. The cavity 36 may be cylindrical or prismatic.

According to the embodiment presented here, the recess 36 comprises three notches 38 positioned on the lateral walls 39 of the recess 36. As can be seen in FIGS. 4 to 7, the gripper 30 has a piercing 41.

The bore 41 is substantially coaxial with the axis A. A first end of the bore 41 opens into the recess 36 and a second end of the bore 41 opens into the protrusion 34. As can be seen, the gripper 30 further comprises , a rod 42.

According to the embodiment presented here, the rod 42 has a substantially flat end 44 and a substantially hemispherical end 45. In addition, the rod 42 has two shoulders 46. A first shoulder 46 extends near the substantially flat end 44 of the stem 42.

The second shoulder 46 is positioned between the first shoulder 46 and the substantially hemispherical end 45, so that the dimension of the rod portion 42 between the two shoulders 46 is greater than or equal to the dimension of the rod portion 42 between the second shoulder 46 and the substantially hemispherical end 45 The rod portion 42 between the two shoulders 46 is slidably mounted in the bore 41. Thus, the two shoulders 46 allow to retain the rod 42 secured to the gripper 30. The gripper 30 may be made of polymeric material resistant to gamma rays. In addition, according to an embodiment not shown here, the outer face 32 of the gripper 30 may have an indexing mark. The ancillary 50 is visible in perspective in Figure 1. The ancillary 50 comprises a head 51, an arm 52, a gripping portion 53 and a strike plate 54. The ancillary can for example be made of stainless steel . The head 51 of the ancillary 50 is shown, in section and in detail, in Figures 4 to 7. The head 51 has a substantially conical shape, centered with respect to the axis A and convergent towards the arm 52.

The head 51 has a substantially flat bearing surface 55 adapted to be positioned against the outer face 32 of the gripper 30. A pin 56 is positioned on the bearing surface 55. The pin 56 is centered with respect to the axis A .

According to the embodiment chosen, the pin 56 may be cylindrical or prismatic. As can be seen in Figures 4 to 7, the stud 56 has an axial housing 57. In use, the axial housing 57 allows the pin 56 to receive the substantially flat end 44 of the rod 42. The nipple 56 has an annular slot 58. The annular slot 58 is open. A radially expandable elastic ring 59 is positioned in the annular slot 58. The elastic ring 59 is adapted to move from a retracted position to an expanded position. The elastic ring may be made of metal alloy or polymer. As can be appreciated in FIGS. 4 to 7, the head 51 has a bore 60. Two open openings 62, substantially parallel to each other and coaxial with the axis A, open into the bore 60 and into the housing respectively. Axial 57. Two pins 64 are slidably mounted each in a through opening 62. The two pins 64 are each positioned facing the annular slot 58. Thus, each peg 64 is in contact with the elastic ring 59. Each peg 64 presents the A cylindrical rod having a distal portion 65 and a proximal portion 66. It is remarkable that the proximal portion 66 of each pin 64 comprises a flat 67. This is a particularly advantageous technical feature of the invention. invention. Indeed, as will be described later, each flat 67 allows each pin 64 to pass the elastic ring 59 in the retracted position or expanded position. The distal portion 65 of each peg 64 has an extra thickness adapted to receive an axis 70 pivotally connecting each peg 64 to a link 75.

According to an embodiment not shown here, the head 51 may, in addition, have an indexing mark corresponding to an indexing mark of the outer face 32 of the gripper 30. As can be seen in FIGS. 3, the arm 52 connects the head 51 5 to the gripping portion 53. According to the embodiment shown here, the arm 52 has a bent shape. However, according to another embodiment not shown here, the arm 52 may have a linear shape. The arm 52 includes a link 75. The link 75 has a shape substantially similar to the shape of the arm 52. The link 75 has a proximal end 76 pivotally attached to the two pins 64. In addition, the link 75 has one end. distal 77 pivotally connected to a handle 79 of the gripping portion 53. The gripping portion 53 allows the holding of the ancillary 50 by a practitioner during the impaction of the acetabulum 10. The gripping portion 53 comprises a handle 79 As can be seen in FIGS. 1 to 3, one end of the handle 79 has two juxtaposed holes. A first hole 80 of the handle 79 allows the handle to be pivotally attached to the grip portion 53. A second bore 81 of the handle 79 allows the handle to be pivotally connected to the link 75. In addition , the handle 79 may comprise a ball 82 snap into an opening 83 of the gripping portion 53. The operation of the assembly 1 will now be described. It is specified that the following description is based on a situation in which the practitioner has prepared the cavity of the patient's pelvic bone. In addition, the following description is based on a situation, represented in FIG. 4, in which the lugs 33 of the gripper 30 are snapped onto the notches 13 of the acetabulum 10. The practitioner must first fix the ancillary device 50 on the gripper 30. To do this, the practitioner introduces the stud 56 into the recess 36. The bearing surface 55 of the head 51 is positioned against the outer face 32 of the gripper 30.

In addition, the substantially flat end 44 of the rod 42 is positioned in the axial housing 57 of the stud 56, facing the proximal portion 66 of each pin 64. As can be seen in FIG. particularly advantageous, portions of the elastic ring 59 are snapped into the notches 38 of the recess 36. In addition, the elastic ring 59 is in the retracted position, in contact with the flats 67 of the pins 64. Thus the practitioner can move the acetabulum From a sterile packaging container to the patient's body, using the gripper 30 and the ancillary 50. The practitioner then impacts the acetabulum 10 into the cavity of the pelvic bone. To this end, the practitioner knocks on the striking plate 53. When the acetabulum 10 is correctly impacted in the patient, the practitioner can eject the acetabulum of the gripper 30. To do this, the practitioner pivots the handle 79. of the handle 79 has the effect of moving the rod 75. The movement of the rod 75 causes the translation of each pin 64 in the corresponding opening 62 opening. The translation of the pawns 64 has two combined effects. As can be appreciated in FIG. 6, the translation of the pins 64 causes the elastic ring 59 to come out of the flats 67. Thus, the elastic ring 59 is held in the expanded position by the pins 64. This technical arrangement makes it possible to lock the fixation between the ancillary 50 and the gripper 30 during the ejection of the acetabulum 10. In addition, the translation of the pins 64 causes the support of the proximal portion 66 of each pin 64 on the substantially flat end 44 of the stem 42. The support of the proximal portion 66 of each pin 64 on the substantially flat end 44 of the rod 42 causes the translation of the rod 42. Thus, as can be seen in FIG. 6, the end substantially hemispherical 45 of the rod exerts a thrust force on the inner surface 12 of the acetabulum. The thrust force thus exerted causes the separation of each lug 35 from the corresponding notch.

In a particularly advantageous manner, the thrust force of the rod 42 in the acetabulum 10 makes it possible to eject the acetabulum 10 of the gripper 30 exerting a force contrary to the direction of withdrawal of the acetabulum 10. As can be seen in FIG. observe in Figure 7, the practitioner can then remove the gripper 30 and the ancillary 50. Thus, the invention provides an assembly 1 for the implantation of a cotyle 10 for separating an acetabulum of an ancillary retaining the Implantation of the acetabulum in the cavity of the iliac bone. Of course, the invention is not limited to the sole embodiment 10 shown above, but it embraces all the embodiments. 15
