The following description of at least one exemplary embodiment is actually only illustrative, and in no way serves as any limitation to the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0022] Such as Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a bone filling block for a pestle and socket joint, comprising: a filling structure 10 for filling in the bone; a socket type structure 20 that is replaceably connected with the filling structure 10, and the socket type structure 20 has The concave articular surface 21 is used for matching with a club joint.
[0023] Applying the technical solution of this embodiment, the bone filling block of the club and socket joint is set as a split structure including a filling structure 10 and a socket type structure 20, wherein the filling structure 10 is used to be filled in the bone to realize the connection with the bone. The articular surface 21 of the structure 20 is used to match the club joint. Since the mortar structure 20 is interchangeably connected with the filling structure 10, the mortar structure 20 with a suitable shape can be selected according to the patient’s specific bone defect, thereby achieving Fills accurately and can restore good articular surface effect. Therefore, the technical solution of the present embodiment can improve the matching effect of the filling bone block of the club and socket joint and the club joint and the applicability of the filling bone block of the club and socket joint. During manufacturing, one filling structure 10 or a plurality of filling structures 10 of the same shape can be provided in a set of filling bone blocks of a pestle and socket joint, and a plurality of socket-shaped structures 20 of different shapes can be provided. In this way, a suitable mortar structure 20 can be selected to be connected to the filling structure 10 according to the needs during use.
[0024] In this embodiment, the acetabular structure 20 includes a plurality of bone dividing blocks 22, and each bone dividing block 22 can be selectively connected to the filling structure 10. In this way, an appropriate number of bone sub-blocks 22 can be selected for matching according to the patient's specific bone defect conditions, so as to achieve accurate filling and restore good articular surface effects. The above arrangement can further improve the scope of application, versatility and flexibility of the bone filling of the pestle and socket joint. in figure 2 The acetabular structure 20 is composed of four bone splitting blocks 22, each splitting block 22 has two planes and a curved surface, wherein the plane of the splitting block 22 is used to match the planes of the other splitting blocks 22 .
[0025] In this embodiment, the bone dividing block 22 has a contact surface 23, and the contact surfaces 23 of a plurality of bone dividing blocks 22 constitute the articular surface 21. In this way, the contact surface 23 of the bone dividing block 22 can contact with the club and socket joint to ensure a good articular surface effect. In this embodiment, the peripheral edge of the articular surface 21 may be circular, elliptical, or the like.
[0026] In this embodiment, the bone filling block of the club and socket joint further includes a first locking portion 30 for detachably connecting the mortar structure 20 and the filling structure 10. The first locking portion 30 can achieve a reliable connection between the mortar structure 20 and the filling structure 10. When in use, first select a suitable mortar structure 20 or select an appropriate number of bone dividing blocks 22 in the mortar structure 20, and then fix the mortar structure 20 on the filling structure 10 through the first locking portion 30.
[0027] Such as image 3 As shown, the first locking portion 30 includes: a first lock rod, which penetrates through the mortar-shaped structure 20, and the first lock rod is detachably connected to the filling structure 10; a lock cap is arranged at one end of the first lock rod, and the mortar-shaped The structure 20 is located between the lock cap and the filling structure 10, and the lock cap is used to compress the mortar structure 20. In this way, a reliable connection between the socket-shaped structure 20 and the filling structure 10 can be achieved through the cooperation of the first lock rod and the lock cap.
[0028] In this embodiment, the first lock rod has an external thread, the filling structure 10 has an internal thread that cooperates with the external thread, the joint surface 21 has a first groove, and the lock cap is located in the first groove. In this way, the connection between the first lock rod and the filling structure 10 can be realized through threaded fit, which is convenient for operation and reliable for connection. By providing the first groove, interference between the lock cap and the pestle joint can be avoided.
[0029] In this embodiment, there are multiple first locking portions 30, and the multiple first locking portions 30 and the multiple bone dividing blocks 22 are arranged in one-to-one correspondence. This can facilitate the connection of the required bone dividing block 22 with the filling structure 10.
[0030] In this embodiment, the mortar structure 20 is angularly adjustable on the filling structure 10. In this way, the relative angle between the acetabular structure 20 and the filling structure 10 can be adjusted according to the patient's specific bone defect conditions, thereby further improving the accuracy of filling and restoring a good articular surface effect. Through the above arrangement, the versatility of filling the bone block of the pestle and socket joint can be improved, and the manufacturing cost can be reduced.
[0031] Specifically, the filling structure 10 has a first connecting surface, and the mortar structure 20 has a second connecting surface. The second connecting surface and the articular surface are respectively located on both sides of the mortar structure 20, and the second connecting surface abuts against the first connecting surface. , The second connecting surface can rotate relative to the first connecting surface. In this way, the relative angle between the mortar structure 20 and the filling structure 10 can be adjusted by rotating the second connecting surface relative to the first connecting surface. In this embodiment, the first connecting surface can be set as a spherical surface or a tapered surface, and correspondingly, the second connecting surface can also be set as a spherical surface or a tapered surface.
[0032] In this embodiment, the bone filling block of the pestle and socket joint further includes a second locking portion, which is used to limit the rotational position of the mortar structure 20 on the filling structure 10. By providing the second locking portion, the reliability of the connection between the mortar structure 20 and the filling structure 10 can be improved, so as to prevent the relative position of the two from changing during use.
[0033] Applying the technical solution of the present invention, the bone filling block of the club and socket joint is set as a split structure including a filling structure 10 and a socket-type structure 20, wherein the filling structure 10 is used to fill the bone to realize the connection with the bone, and the socket-type structure The articular surface 21 of 20 is used to match the club joint. Since the mortar structure 20 is interchangeably connected with the filling structure 10, the mortar structure 20 with a suitable shape can be selected according to the patient’s specific bone defect, thereby achieving precision Fill and restore good articular surface effect. Therefore, the technical solution of the present invention can improve the matching effect of the stuffing bone block of the club and socket joint and the club joint and the applicability of the stuffing bone block of the club and socket joint. The technical solution is an adjustable bone filling block. The mortar structure 20 can be accurately filled according to the defect form of the patient. By selecting a suitable mortar structure 20 to connect with the filling structure 10, the physiological structure of the articular surface can be perfectly restored to achieve a good The purpose of fixing acetabular prosthesis.
