[0002] Hip replacement is to fix an artificial prosthesis (including the femoral part and the acetabulum part) on normal bone to replace the diseased joint and reconstruct the normal function of the patient's hip joint. Among them, the acetabulum part includes the acetabular cup, which needs to be clamped by a cup holding instrument during the operation and then inserted into the acetabular socket. In addition, the cup holding instrument also needs to provide a driving and pulling platform for the surgeon to drive the acetabular cup into the acetabular socket and fix it.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0037] Figure 1 is a schematic structural diagram of a prosthesis implant assembly according to an embodiment of the present application, Figure 2 yes Figure 1 Schematic diagram of the exploded structure of the prosthetic implant components shown, Figure 3 yes Figure 1 Schematic diagram of the cross-sectional structure along direction DD, for ease of understanding, Figure 1 to Figure 2 Also shown is the target prosthesis 1. Figures 1 to 3 , the prosthesis implant assembly 100 of the present application includes a power receiving device 10 and a cup holding device 20. The power receiving device 10 includes a central axis 13 capable of receiving impact. The cup holding device 20 can be detachably connected to the target prosthesis 1 to be implanted. Among them, the cup holding device 20 is detachably connected to the power receiving device 10 through a connecting mechanism 30. The connecting mechanism 30 includes a first connecting portion 33 and a second connecting portion 34, and the first connecting portion 33 and the second connecting portion 34 are respectively arranged on the power receiving device 10 and the cup holding device 20, and the first connecting portion 33 and the second connecting portion 34 are constructed to make the power receiving device 10 and the cup holding device 20 relatively fixed when connected, so that the impact received by the central axis 13 is axially transmitted to the cup holding device 20.

[0038] The power receiving device 10 and the cup holding device 20 are two independently formed devices, and the two can be detachably connected together through a connecting mechanism 30. It should be noted that the cup holding device 20 and the power receiving device 10 can be detachably connected through the connecting mechanism 30, which means that the cup holding device 20 and the power receiving device 10 can be connected together under the action of the connecting mechanism 30, and the cup holding device 20 and the power receiving device 10 can be detached into two independent devices after being connected through the connecting mechanism 30, and the separation is realized again.

[0039] The detachable connection method between the cup holding device 20 and the power receiving device 10 includes but is not limited to threaded connection, snap connection, etc.

[0040] The cup holding device 20 can be detachably connected to the target prosthesis 1, which means that the cup holding device 20 can be connected to the target prosthesis 1, and the cup holding device 20 and the target prosthesis 1 can be detached from each other after being connected to release the target prosthesis 1. The detachable connection between the cup holding device 20 and the target prosthesis 1 includes but is not limited to threaded connection, clamping, etc.

[0041] The central axis 13 can receive impacts. The impact can come from actions such as knocking and hammering. When the first connection portion 33 and the second connection portion 34 are connected, the cup holding device 20 and the power receiving device 10 are relatively fixed, that is, the two will not produce relative displacement, and the connection is relatively firm. At this time, the impact received by the central axis 13 can be axially transmitted to the cup holding device 20, thereby indirectly acting on the target prosthesis 1 connected to the cup holding device 20, so that the target prosthesis 1 can be fixed to the target object's implantation position.

[0042] The prosthesis implant assembly 100 may further include a tracer 12, which is fixedly connected to the central axis 13, and the tracer 12 can provide the navigator with its spatial position information. When the power receiving device 10 and the cup holding device 20 are connected, the spatial position relationship between the two remains fixed, and the navigator can indirectly obtain the spatial position information of the target prosthesis loaded on the cup holding device 20 through the spatial position information provided by the tracer 12.

[0043] The prosthesis implant assembly 100 provided in the embodiment of the present application is detachably connected by connecting the cup holding device 20 and the power receiving device 10 through a connecting mechanism 30. During the operation, the target prosthesis 1 can be first installed on the cup holding device 20, and then the cup holding device 20 with the target prosthesis 1 can be inserted into the target object, and finally the cup holding device 20 and the power receiving device 10 can be connected together through the connecting mechanism 30. Since the cup holding device 20 is detachably connected to the power receiving device 10, the cup holding device 20 connected to the target prosthesis 1 can be separately inserted into the position to be implanted in the target object. The length of the cup holding device 20 is limited and is not connected to the robot arm. Therefore, the insertion of the cup holding device 20 will not be limited by the position and range. The insertion operation is simple and quick, which speeds up the operation process and shortens the operation time. After being inserted into the position to be implanted, the cup holding device 20 is connected to the power receiving device 10, so that the precise position of the target prosthesis 1 can be determined under the guidance of the robot arm, and the target prosthesis 1 can be fixed at the position to be implanted by hitting the central axis 13 of the power receiving device 10, thereby achieving accurate implantation of the target prosthesis 1. When the first connecting portion 33 and the second connecting portion 34 are in a connected state, the cup holding device 20 and the power receiving device 10 are relatively fixed, and the connection is relatively stable, which is conducive to the axial transmission of the impact received by the central axis 13 to the cup holding device 20, thereby accurately implanting the target prosthesis 1 at the position to be implanted.

[0044] In some embodiments, the connecting mechanism 30 includes a first positioning portion and a second positioning portion, which are respectively arranged on the power receiving device 10 and the cup holding device 20. The first positioning portion and the second positioning portion are plug-fitted into the axial holes and can be relatively moved axially.

[0045] One of the first positioning part and the second positioning part is a pin structure, and the other is a pin hole structure, and the pin structure is inserted into the pin hole structure. The first positioning part and the second positioning part can move relative to each other along the axial direction, so that the first positioning part and the second positioning part can be inserted or separated, thereby realizing the connection and disassembly of the power receiving device 10 and the cup holding device 20.

[0046] Optionally, the first positioning portion may be a first positioning column 31 provided on the power receiving device 10 , and the second positioning portion may be a first positioning hole 32 provided on the cup holding device 20 , and the first positioning column 31 may be movably inserted into the first positioning hole 32 .

[0047] Optionally, the first positioning portion may also be a positioning hole provided on the power receiving device 10 , and correspondingly, the second positioning portion may be a positioning column provided on the cup holding device 20 , and the positioning column is inserted into the positioning hole.

[0048] The power receiving device 10 and the cup holding device 20 are positioned by means of a first positioning portion and a second positioning portion that are plugged into an axial hole. This axial hole plug-in method is not only simple and quick to operate, but also helps to improve the coaxiality of the power receiving device 10 and the cup holding device 20, making it easier to accurately determine the position of the target prosthesis 1.

[0049] Figure 4 yes Figure 3 The enlarged structural diagram of the area E in the middle. In some embodiments, the first connecting portion 33 and the second connecting portion 34 are connected by a threaded structure.

[0050] The threaded connection is stable, and the connection and disassembly operations are relatively simple. More importantly, the connection and disassembly operations will not damage the structure and life of the first connection part 33 and the second connection part 34, and the repeatability is strong, which is particularly suitable for the power receiving device 10 and the cup holding device 20 that need to be separated and connected.

[0051] In some embodiments, the first connecting portion 33 is rotatably sleeved on the second end 132 of the central shaft 13 in the axial direction, and is movably arranged along the axial direction of the central shaft 13. The central shaft 13 extends straight, and the first end 131 opposite to the second end 132 in the axial direction thereof is used to receive impact, and the impact received by the first end 131 is axially transmitted to the second end 132.

[0052] The first connection portion 33 has an internal thread 331 , and the second connection portion 34 has an external thread 341 . The first connection portion 33 and the second connection portion 34 are threadedly connected via the internal thread 331 and the external thread 341 .

[0053] The first connection part 33 may be a nut structure sleeved on the second end 132 of the central axis. When the first connection part 33 moves along one of the axial directions of the central axis 13 and rotates around the central axis 13 at the same time, the second connection part 34 gradually enters the interior of the first connection part 33, and the external thread 341 of the second connection part 34 is threadedly connected with the internal thread 331 of the first connection part 33. When the first connection part 33 moves along the other axial direction of the central axis 13 and rotates in the opposite direction around the central axis 13 at the same time, the second connection part 34 gradually moves out of the first connection part 33, and after the external thread 341 of the second connection part 34 is axially separated from the internal thread 331 of the first connection part 33, the connection between the first connection part 33 and the second connection part 34 is released.

[0054] The first positioning column 31 extends axially outward from the second end 132 of the central shaft 13. The first positioning column 31 and the central shaft 13 coincide with each other. After the first positioning column 31 is inserted into the first positioning hole 32, the first connecting portion 33 is detachably connected to the second connecting portion 34.

[0055] The impact received by the first end 131 of the central axis 13 can be axially transmitted through the central axis 13 to the first connecting portion 33 at the second end 132 of the central axis, and then transmitted to the cup holding device 20 through the second connecting portion 34. The axial transmission of the impact can reduce the possibility of the target prosthesis 1 being deviated.

[0056] In some embodiments, the connecting mechanism 30 also includes a first elastic member 35, which is arranged inside the first connecting portion 33 along the axial direction of the central axis 13, and one end of the first elastic member 35 abuts against the first connecting portion 33, and the other end abuts against the axial limiting portion 133 on the central axis 13, so as to push the power receiving device 10 and the cup holding device 20 to axially engage when the first connecting portion 33 and the second connecting portion 34 are connected.

[0057] The first elastic member 35 is disposed along the axial direction of the central axis 13 , and can generate compressive deformation and tensile deformation along the axial direction of the central axis 13 .

[0058] Optionally, the first elastic member 35 may be a spring.

[0059] When the first connection part 33 is connected to the second connection part 34, the first elastic member 35 is squeezed by the first connection part 33 and the axial limit part 133 to produce compression deformation and accumulate elastic potential energy. At this time, the other end of the first elastic member 35 applies a thrust to the axial limit part 133, prompting the axial limit part 133 to axially press the cup holding device 20. The axial limit part 133 is fixedly connected or integrally formed with the central axis 13. Therefore, the first elastic member 35 can effectively push the power receiving device 10 and the cup holding device 20 to axially engage, thereby improving the connection effect between the two. When the first connection part 33 and the second connection part 34 are disconnected, the elastic potential energy accumulated by the first elastic member 35 is gradually released. In the process of releasing the elastic potential energy, the first elastic member 35 automatically lifts the first connection part 33 away from the axial limit part 133, thereby exposing the second connection part 34, which is conducive to the disassembly between the power receiving device 10 and the cup holding device 20.

[0060] The axial limiting portion 133 radially protrudes from the central axis 13. The second connecting portion 34 may be a connecting column, and an external thread 341 is formed on the outer peripheral surface of the connecting column. The first positioning hole 32 may be axially penetrated through the second connecting portion 34. After the first positioning column 31 and the first positioning hole 32 axial hole are matched, the axial limiting portion 133 may abut against an end surface of the second connecting portion 34 in the axial direction.

[0061] Figure 5 yes Figure 1 A schematic diagram of the structure of the cup holding device of the prosthesis implant assembly shown. In some embodiments, the cup holding device 20 includes a first end 21 and a second end 22 that are arranged opposite to each other, and a cup holding rod 23 connected between the first end 21 and the second end 22, the first end 21 is detachably connected to the power receiving device 10, the second end 22 can be detachably connected to the target prosthesis 1, and the cup holding rod 23 is bent and / or extended from the first end 21 to the second end 22.

[0062] The second connection portion 34 may be provided at the first end 21 of the cup holding device 20 so as to be threadedly connected to the first connection portion 33 on the power receiving device 10. Optionally, the first end 21 may be detachably connected to the power receiving device 10 via the second connection portion 34, or may be detachably connected to the power receiving device 10 via other connection structures.

[0063] The cup holding rod 23 can extend from the first end 21 to the second end 22 after being bent at least once, or can extend from the first end 21 to the second end 22 after being bent at least once, or can extend from the first end 21 to the second end 22 after being bent at least once and bent at least once.

[0064] The cup holding rod 23 is bent and / or extended from the first end 21 to the second end 22, and a clearance space can be formed between the first end 21 and the second end 22. When the cup holding device 20 carries the target prosthesis and implants it into the position to be implanted in the target object, the clearance space can avoid the soft tissue and bones of the target object at the incision position everted, thereby preventing the cup holding device 20 from causing damage to the soft tissue and bones at the incision position everted in the target object during the operation.

[0065] In some embodiments, the first end 21 and the power receiving device 10 are detachably connected along the first axis direction X, and the second end 22 and the target prosthesis 1 are detachably connected along the second axis direction Y. The cup holding rod 23 includes a first rod segment 231 and a second rod segment 232 extending straight, and the central axis M of the first rod segment 231 and the central axis N of the second rod segment 232 intersect. The first rod segment 231 is connected to the first end 21, and the central axis M of the first rod segment 231 intersects with the first axis direction X. The second rod segment 232 is connected to the second end 22, and the central axis N of the second rod segment 232 intersects with the second axis direction Y.

[0066] The central axis M of the first rod segment 231 and the central axis N of the second rod segment 232 intersect, that is, an angle is formed between the first rod segment 231 and the second rod segment 232 , and the connection position of the first rod segment 231 and the second rod segment 232 forms a bending point of the cup holding rod 23 .

[0067] The first end 21 and the power receiving device 10 are connected together along the first axis direction X, and are mutually disassembled along the first axis direction X. The first end 21 is connected to the first rod segment 231, and the center axis M of the first rod segment 231 intersects with the first axis direction X, that is, the connection and disassembly direction of the first end 21 and the power receiving device 10 forms an angle with the first rod segment 231, and the first rod segment 231 deviates from the connection and disassembly direction of the first end 21 and the power receiving device 10, which is conducive to reserving space in the connection and disassembly direction of the first end 21 and the power receiving device 10, and is conducive to smooth installation and disassembly of the power receiving device 10 and the cup holding device 20.

[0068] The second end 22 and the target prosthesis 1 are connected together along the second axial direction Y, and are mutually disassembled along the second axial direction Y. The second end 22 is connected to the second rod segment 232, and the central axis N of the second rod segment 232 intersects with the second axial direction Y, that is, the connection and disassembly direction of the second end 22 and the target prosthesis 1 forms an angle with the second rod segment 232, and the second rod segment 232 deviates from the connection and disassembly direction of the second end 22 and the target prosthesis 1, which is conducive to reserving space in the connection and disassembly direction of the second end 22 and the target prosthesis 1.

[0069] In the embodiment of the present application, the cup holding rod 23 is configured to be a two-section structure of a first rod section 231 and a second rod section 232 . The structure is simple, and the formed clearance space can effectively avoid the corresponding tissues and bones of the target object.

[0070] In some embodiments, the sum of the first angle α between the central axis M of the first rod segment 231 and the central axis N of the second rod segment 232, the second angle β between the central axis M of the first rod segment 231 and the first axis direction X, and the third angle γ between the central axis N of the second rod segment 232 and the second axis direction Y is 180°. At this time, the first axis direction X and the second axis direction Y coincide, and the first angle α, the second angle β, and the third angle γ may be exactly the three internal angles of a triangle.

In some embodiments, the cup holding device 20 includes a first end 21 and a second end 22 that are relatively arranged, the first end 21 is detachably connected to the power receiving device 10, and the second end 22 is provided with a switching mechanism 24 and a first locking mechanism 25, the switching mechanism 24 is axially movably plugged into the second end 22, and can be detachably connected to the target prosthesis 1. The first locking mechanism 25 is configured to selectively axially lock or release the switching mechanism 24 and the second end 22. In the locked state, the switching mechanism 24 is axially fixed to the second end 22; in the released state, the switching mechanism 24 can move axially relative to the second end 22 to separate from the second end 22.

[0072] When the first locking mechanism 25 axially locks the adapter mechanism 24 and the second end 22, the adapter mechanism 24 is axially fixed to the second end 22, and the target prosthesis 1 connected to the adapter mechanism 24 is indirectly loaded into the second end 22 through the adapter mechanism 24, thereby realizing the cup holding operation of the cup holding device 20. When the first locking mechanism 25 axially releases the adapter mechanism 24 and the second end 22, the adapter mechanism 24 can axially move relative to the second end 22 and move out from the second end 22, thereby realizing the rapid disassembly of the adapter mechanism 24, which is beneficial to the maintenance, cleaning, replacement, etc. of the adapter mechanism 24.

[0073] The embodiment of the present application provides the adapter mechanism 24, so that the target prosthesis 1 can be connected to the adapter mechanism 24 first, and then the adapter mechanism 24 can be connected to the second end 22. The adapter mechanism 24 has a compact structure, which is convenient for connection with the target prosthesis 1. In addition, the embodiment of the present application is also provided with a first locking mechanism 25, through which the adapter mechanism 24 and the second end 22 are quickly axially locked or released, so that the adapter mechanism 24 can be quickly installed and disassembled, which is conducive to speeding up the surgical process and facilitating the maintenance, cleaning, replacement, etc. of the adapter mechanism 24.

[0074] In some embodiments, the switching mechanism 24 includes a locking shaft 241 and a connecting shaft 242 that are coaxially arranged, and the outer diameter of the connecting shaft 242 is greater than the outer diameter of the locking shaft 241. The first locking mechanism 25 includes a locking block 251. Figure 7 yes Figure 1 The structural diagram of the locking block and the switching mechanism of the prosthesis implant assembly shown in FIG. Figure 8 yes Figure 1 The structural diagram of the locking block of the prosthesis implant component is shown. Figures 6 to 8 The locking block 251 defines a locking hole 252 and a release hole 253 inside. The diameter of the locking hole 252 is smaller than the outer diameter of the connecting shaft 242, and the diameter of the release hole 253 is larger than the outer diameter of the connecting shaft 242. The locking block 251 is movably disposed inside the second end 22. In the locked state, the locking shaft 241 passes through the locking hole 252, and the connecting shaft 242 axially abuts against the locking block 251; in the released state, the locking shaft 241 passes through the release hole 253, so that the connecting shaft 242 can move axially relative to the locking block 251.

[0075] In the locked state, the locking shaft 241 is inserted into the locking hole 252. Since the diameter of the locking hole 252 is smaller than the outer diameter of the connecting shaft 242, the connecting shaft 242 cannot pass through the locking hole 252, but axially abuts against the locking block 251, thereby limiting the transfer mechanism 24 from being separated from the locking block 251. In the released state, the locking block 251 moves to make the locking shaft 241 pass through the release hole 253. Since the diameter of the release hole 253 is larger than the outer diameter of the connecting shaft 242, the limit of the connecting shaft 242 fails, and the connecting shaft 242 can pass through the release hole 253, thereby axially moving out of the release hole 253 relative to the locking block 251, thereby releasing the connection between the transfer mechanism 24 and the locking block 251.

[0076] The diameter of the locking hole 252 means the diameter of the circular hole where the locking hole 252 is located, and the diameter of the releasing hole 253 means the diameter of the circular hole where the releasing hole 253 is located. The locking hole 252 and the releasing hole 253 are partial hole areas of two different circular holes.

[0077] The connection between the adapter mechanism 24 and the target prosthesis 1 includes, but is not limited to, threaded connection, clamping, etc. Specifically, the adapter mechanism 24 also includes a prosthesis connection portion 243, which can be threadedly connected to the target prosthesis 1. The prosthesis connection portion 243 can be coaxially arranged with the connecting shaft 242 to facilitate determining the axis of the target prosthesis 1.

[0078] The above-mentioned embodiment of the present application can realize the locking or releasing of the adapter mechanism 24 and the second end 22 only by moving the locking block 251 so that the locking shaft 241 selectively passes through the locking hole 252 or the release hole 253 in the locking block 251. The operation is simple and the structural design is ingenious.

[0079] In some embodiments, the locking holes 252 and the release holes 253 are arranged and communicated along the radial direction of the second end 22. The first locking mechanism 25 further includes a second elastic member 254, which is arranged along the arrangement direction of the locking holes 252 and the release holes 253. One end of the second elastic member 254 abuts against one side of the locking block 251 adjacent to the locking hole 252, and the other end abuts against the inner wall of the second end 22, so that the locking block 251 moves radially inside the second end 22.

[0080] The locking hole 252 may be a partial hole area of ​​the first circular hole, and the releasing hole 253 may be a partial hole area of ​​the second circular hole. The centers of the first circular hole and the second circular hole do not overlap. The first circular hole and the second circular hole are arranged and overlapped along the radial direction of the second end 22 to form a whole.

[0081] The second elastic member 254 is disposed along the radial direction of the second end 22, and the second elastic member 254 can generate compression deformation or tension deformation along the radial direction of the second end 22. Optionally, the second elastic member 254 can be a spring.

[0082] When the locking block 251 is squeezed in the radial direction of the second end 22 toward the direction close to the second elastic member 254, the second elastic member 254 is squeezed to produce compression deformation, and the release hole 253 of the locking block 251 moves toward the direction close to the locking shaft 241. When the release hole 253 is axially opposite to the locking shaft 241, the limiting function of the connecting shaft 242 fails, and the adapter mechanism 24 can move axially relative to the locking block 251 and be removed from the second end 22. When the external force squeezing the locking block 251 disappears, the second elastic member 254 recovers its deformation, radially pushes the locking block 251 to move radially away from the second elastic member 254, and the locking hole 252 of the locking block 251 moves toward the direction close to the locking shaft 241. When the locking shaft 241 is inserted into the locking hole 252, the connecting shaft 242 abuts against the axial end face of the locking block 251, realizing the axial limiting between the adapter mechanism 24 and the locking block 251.

[0083] In the absence of external squeezing, the second elastic member 254 can force the locking block 251 to remain in the locked state, thereby improving the structural stability of the first locking mechanism 25 in the locked state.

[0084] In some embodiments, the first locking mechanism 25 further includes a protrusion 255 , which is disposed on the radial side of the locking block 251 away from the second elastic member 254 and is exposed or protrudes outside the second end 22 through a through hole on the second end 22 .

[0085] The protrusion 255 can be exposed to the outside of the cup holding rod 23 through the through hole on the second end 22 , but the protrusion 255 is still entirely located inside the second end 22 .

[0086] The protrusion 255 may also radially protrude outside the second end 22 through the through hole on the second end 22 . The protrusion 255 is partially located inside the second end 22 and partially located outside the second end 22 .

[0087] The embodiment of the present application provides an operating position for the extrusion locking block 251 by setting a protrusion 255, which is more conducive to the quick installation and quick disassembly of the adapter mechanism 24. Different adapter mechanisms 24 have different types of connectors, which can achieve connection with various types of target prostheses 1 and connect them to the cup holding device 20.

[0088] Fig. 9 yes Figure 1 A schematic diagram of the structure of the cup holding device of the prosthetic implant assembly in one of the disassembled states, Fig.10 yes Figure 1 A schematic diagram of the structure of the cup holding device of the prosthesis implant assembly shown in another exploded state. In some embodiments, the cup holding device 20 includes a cup holding rod 23, and the cup holding rod 23 includes a body 233, a cover 234, a transmission rod 235 and a second locking mechanism 236. The body 233 and the cover 234 cover each other and define a receiving space 237. The transmission rod 235 is at least partially disposed in the receiving space 237 and can be directly or indirectly connected to the target prosthesis 1. The second locking mechanism 236 is configured to selectively lock or release the body 233 and the cover 234 along the first direction A.

[0089] Optionally, the transmission rod 235 may be indirectly connected to the target prosthesis 1 via the adapter mechanism 24. That is, the adapter mechanism 24 is connected to the transmission rod 235 of the cup holding rod 23.

[0090] Specifically, one end of the transmission rod 235 is connected to the connecting shaft 242 of the switching mechanism 24, and the other end of the transmission rod 235 is connected to the operating portion 238. The operating portion 238 is located outside the accommodating space 237, so that the transmission rod 235 can be rotated by the operating portion 238. The rotation of the transmission rod 235 drives the switching mechanism 24 to rotate, so that the switching mechanism 24 can be detached from the target prosthesis 1, and the cup holding device 20 and the target prosthesis 1 can be separated.

[0091] A polygonal shaft hole 244 may be formed inside the connecting shaft 242 , and one end of the transmission rod 235 is inserted into the shaft hole 244 inside the connecting shaft 242 and matched with the shape of the shaft hole 244 , so that the connecting shaft 242 can be driven to rotate synchronously when the transmission rod 235 rotates.

[0092] The first direction A may be parallel to the arrangement direction of the body 233 and the cover 234. The second locking mechanism 236 locks the body 233 and the cover 234 along the first direction A. The body 233 and the cover 234 cover each other to form a whole, and hide the transmission rod 235 inside. The rotation of the transmission rod 235 will not interfere with or affect other structures. The second locking mechanism 236 releases the body 233 and the cover 234 along the first direction A, and the cover 234 can be removed from the body 233, which is convenient for disassembly, cleaning or replacement of the transmission rod 235, etc.

[0093] The embodiment of the present application realizes quick installation and quick disassembly of the cup holding rod 23 through the second locking mechanism 236 , which facilitates the cleaning of the various components of the cup holding rod 23 and improves the safety of the cup holding device 20 .

[0094] In some embodiments, the second locking mechanism 236 includes a locking pin 2361 arranged along the first direction A, the locking pin 2361 is rotatably inserted into the body 233, and a stop pin 2362 is provided at one end of the locking pin 2361 axially close to the cover 234. The cover 234 is provided with a locking hole 2341 penetrating the cover 234 along the first direction A. In the locked state, the locking pin 2361 is inserted into the locking hole 2341, and the stop pin 2362 abuts against the cover 234 at a side of the cover 234 away from the body 233, thereby causing the cover 234 to be connected to the body 233; in the released state, the stop pin 2362 can pass through the locking hole 2341 along the first direction A, the stop pin 2362 fails to limit the cover 234, and the cover 234 can be removed from the body 233.

[0095] The locking state and the releasing state of the locking pin 2361 can be switched by rotating the locking pin 2361. This switching method is easy to operate and is conducive to improving the disassembly and assembly efficiency of the cup holding rod 23.

[0096] The shape of the locking hole 2341 can match the shape of the limiting pin 2362. For example, the locking hole 2341 and the limiting pin 2362 can both be straight. When the limiting pin 2362 is driven by the locking pin 2361 to rotate to a state where it completely overlaps with the locking hole 2341, the limiting pin 2362 can pass through the locking hole 2341 along the first direction A. When the limiting pin 2362 is driven by the locking pin 2361 to rotate to a state where it does not completely overlap with the locking hole 2341, the limiting pin 2362 cannot pass through the locking hole 2341 along the first direction A, but abuts against the cover body 234, thereby restricting the cover body 234.

[0097] Furthermore, the cover body 234 is also provided with a locking groove adjacent to the locking hole 2341, and the locking groove is recessed into the inside of the cover body 234. When the second locking mechanism 236 is in the locked state, the stop pin 2362 can abut against the locking groove. At this time, the stop pin 2362 can be hidden in the locking groove and will not protrude outward from the surface of the cover body 234, effectively avoiding the problem of positional misalignment of the stop pin 2362 due to accidental contact, and the locking state is more stable. Optionally, the locking groove can be a straight groove, which together with the locking hole 2341 forms a cross-shaped recessed structure.

[0098] In some embodiments, the second locking mechanism 236 also includes a third elastic member 2363, which is sleeved on the locking pin 2361, one end of which abuts against the main body 233, and the other end abuts against the axial limiting portion 2368 on the locking pin 2361, and the axial limiting portion 2368 and the limiting pin 2362 are respectively located at two axially opposite ends of the locking pin 2361.

[0099] When the second locking mechanism 236 is switched from the locked state to the released state, the locking pin 2361 can be pushed by the axial limiting portion 2368, and the third elastic member 2363 can be axially pressed to make the limiting pin 2362 away from the cover body 234 by a certain distance; then the locking pin 2361 can be rotated until the limiting pin 2362 and the locking hole 2341 are completely overlapped. During the rotation process, the limiting pin 2362 will not generate friction with the cover body 234, thereby avoiding damage to the cover body 234. When the second locking mechanism 236 is switched from the released state to the locked state, the locking pin 2361 can be pushed by the axial limiting portion 2368, and the third elastic member 2363 can be axially pressed to make the limiting pin 2362 away from the cover body 234 by a certain distance; then the locking pin 2361 can be rotated until the limiting pin 2362 and the locking hole 2341 do not completely overlap, and then the locking pin 2361 can be released.

[0100] Optionally, the third elastic member 2363 may be a spring.

[0101] The third elastic member 2363 is provided in the embodiment of the present application to increase the pressing force of the limit pin 2362 on the cover 234, thereby ensuring the structural stability of the cup holding rod 23 in the working state. In addition, the third elastic member 2363 can prevent the cover 234 from being damaged during the state switching process of the second locking mechanism 236.

[0102] In some embodiments, the second locking mechanism 236 includes a first pin hole 2364, a first shaft pin 2365, a second pin hole 2366, and a second shaft pin 2367. One of the first pin hole 2364 and the first shaft pin 2365 is provided on the body 233, and the other is provided on the cover 234. The first pin hole 2364 and the first shaft pin 2365 are plugged together along the second direction B. One of the second pin hole 2366 and the second shaft pin 2367 is provided on the body 233, and the other is provided on the cover 234. The second pin hole 2366 and the second shaft pin 2367 are plugged together along the third direction C. The first direction A, the second direction B, and the third direction C intersect each other.

[0103] The first pin hole 2364 may be a closed hole-shaped structure or a semi-closed slot-shaped structure extending along the second direction B. Similarly, the second pin hole 2366 may be a closed hole-shaped structure or a semi-closed slot-shaped structure extending along the third direction C.

[0104] Optionally, the second direction B may be parallel to the central axis N of the second rod segment 232 of the cup holding rod 23 , and the third direction C may be parallel to the first axis direction X and / or the second axis direction Y.

[0105] The shape of the first shaft pin 2365 matches that of the first pin hole 2364 . The shape of the second shaft pin 2367 matches that of the second pin hole 2366 .

[0106] For ease of operation, the first shaft pin 2365 and the second shaft pin 2367 may be disposed on the cover 234 , and the first pin hole 2364 and the second pin hole 2366 may be disposed on the body 233 .

[0107] After the locking pin 2361 is switched to the released state, the cover body 234 can be manually pushed so that the first axle pin 2365 and the second axle pin 2367 are respectively removed from the first pin hole 2364 and the second pin hole 2366 to completely remove the cover body 234 from the main body 233 .

[0108] The plugging directions of the first pin hole 2364 and the first axial pin 2365, the second pin hole 2366 and the second axial pin 2367, and the locking directions of the main body 233 and the cover body 234 intersect with each other, so that the main body 233 and the cover body 234 can be positioned in multiple directions, which is more conducive to the precise assembly of the main body 233 and the cover body 234.

[0109] In some embodiments, the cup holding device 20 and the power receiving device 10 are detachably connected along a first axial direction X, and the cup holding device 20 and the target prosthesis 1 are detachably connected along a second axial direction Y, and both the first axial direction X and the second axial direction Y coincide with the axis of the central axis 13.

[0110] The first axial end 131 of the central shaft 13 can receive impact, and the second axial end 132 of the central shaft 13 is detachably connected to the cup holding device 20. The impact received by the first end 131 of the central shaft 13 can be axially transmitted to the cup holding device 20 at the second end 132 of the central shaft through the central shaft 13, and the impact is axially transmitted, which can reduce the possibility of the target prosthesis 1 being deviated.

[0111] After the power receiving device 10, the cup holding device 20 and the target prosthesis 1 are connected, the positional relationship between the target prosthesis 1 and the tracer on the power receiving device 10 can be accurately established, and then the real-time position of the target prosthesis 1 can be calculated through the tracer on the power receiving device 10 during the operation, thereby improving the surgical effect.

[0112] In some embodiments, the cup holding device 20 includes a first end 21, a second end 22, and a switching mechanism 24. The first end 21 is provided with a first positioning hole 32, and the power receiving device 10 is plugged into the first positioning hole 32. The second end 22 is provided with a second positioning hole 221, and the switching mechanism 24 is plugged into the second positioning hole 221. The first positioning hole 32 and the second positioning hole 221 are concentric, and the second axis direction Y passes through the axis of the second positioning hole 221.

[0113] The first positioning hole 32 and the second positioning hole 221 can be processed by the same machining process to reduce errors and ensure that the two have a high degree of coaxiality, so that after the power receiving device 10, the cup holding device 20 and the target prosthesis 1 are connected, the power receiving device 10, the adapter mechanism 24 and the target prosthesis 1 have a high degree of coaxiality.

[0114] Fig.11 3 is a schematic diagram of a prosthesis implantation device provided by an embodiment of the present application in a use state. In some embodiments, the first positioning hole 32 may be a through hole. The first positioning hole 32 is also used to connect the tracing device 2 to register the position of the target prosthesis 1.

[0115] The power receiving device 10 is inserted into one axial end of the first positioning hole 32 , and the tracer device 2 is connected to the other axial end of the first positioning hole 32 , so that the power receiving device 10 , the tracer device 2 and the target prosthesis 1 are coaxial.

[0116] Registering the position of the target prosthesis 1 refers to determining the position of the bottom end point of the target prosthesis 1 . For example, the specific coordinate value of the bottom end point of the target prosthesis 1 can be determined in a preset coordinate system.

[0117] The tracer device 2 can cooperate with the tracer 12 on the power receiving device 10 to accurately determine the position of the target prosthesis 1 with high accuracy, which is conducive to improving the quality of surgery.

[0118] According to the second aspect of the present application, an embodiment of the present application further provides a surgical device 1000 . Fig.12 1 is a schematic diagram of the structure of a surgical device provided in an embodiment of the present application. The surgical device 1000 provided in an embodiment of the present application comprises a prosthetic implant assembly 100 and a robot arm 200 provided in any of the above embodiments.

[0119] Furthermore, the surgical device 1000 may also include an orthopedic positioner, which is used in conjunction with the prosthesis implant assembly 100 to more accurately determine the position of the target prosthesis 1.

[0120] Furthermore, the surgical device 1000 may also include a controller 300 and a surgical platform 400. The controller 300 is coded to control the robot arm 200 and the prosthesis implant assembly 100 to act according to a predetermined surgical plan. The surgical platform 400 is used to support the target object to be operated on and provide a surgical operation platform.
