The above-mentioned setting can make the connection stability between the first connectingarm 22 and thepulley part 30 better, and the extending direction of the central plane of the limitingblock 222 is the same as the extending direction of the connectinghandle 10, and thus the limitingblock 222 can be limited Move inbit slot 321.

如图9所示，在本实施例中，连接柄10包括第一杆体11、第二杆体12以及连接块13，第一杆体11和第二杆体12间隔设置且均设置在连接块13的同一表面，第一杆体11的长度大于第二杆体12的长度。上述的第一杆体11插入至肱骨髓腔内，第二杆体12位于肱骨的外侧，在通过紧固件连接在第一杆体11、第二杆体12以及肱骨，这样能够保证连接的稳定性。As shown in FIG. 9 , in this embodiment, the connectinghandle 10 includes afirst rod body 11 , asecond rod body 12 and a connectingblock 13 , and thefirst rod body 11 and thesecond rod body 12 are arranged at intervals and are all arranged on the same side of the connectingblock 13 . On the surface, the length of thefirst rod body 11 is greater than the length of thesecond rod body 12 . The above-mentionedfirst rod body 11 is inserted into the medullary cavity of the humerus, and thesecond rod body 12 is located on the outside of the humerus, and is connected to thefirst rod body 11, thesecond rod body 12 and the humerus through fasteners, which can ensure the stability of the connection.

如图9所示，在本实施例中，第一杆体11插入肱骨髓腔部分可带有网格结构，便于骨整合；也可用于水泥固定，第一杆体11的截面呈梯形，起到防旋的作用，且在第一杆体11远离第二杆体12的一侧上设计有凹槽，增加防旋功能；第二杆体12上带有网格结构，允许与植入骨的骨整合，增加长期稳定性；且植骨仓121的存在可允许填充骨的高度调整，使得第二杆体、填充骨以及肱骨皮质之间更好的贴附。As shown in Figure 9, in this embodiment, the part of thefirst rod body 11 inserted into the medullary cavity of the humerus can have a grid structure to facilitate osseointegration; it can also be used for cement fixation, and the cross section of thefirst rod body 11 is trapezoidal to prevent The role of rotation, and a groove is designed on the side of thefirst rod body 11 away from thesecond rod body 12, which increases the anti-rotation function; thesecond rod body 12 has a grid structure, allowing osseointegration with the implanted bone, increasing Long-term stability; and the presence of thebone graft chamber 121 can allow the height adjustment of the filling bone, making better attachment between the second rod, filling bone and humeral cortex.

如图9所示，在本实施例中，第二杆体12朝向第一杆体11的一侧间隔设置有多个植骨仓121。植骨仓121的内部填充自体骨或者异体骨，这样能够与肱骨长合在一起，进而能够提高连接的效果。As shown in FIG. 9 , in this embodiment, a plurality ofbone graft chambers 121 are arranged at intervals on one side of thesecond rod body 12 facing thefirst rod body 11 . The interior of thebone graft chamber 121 is filled with autologous bone or allogeneic bone, so that it can grow together with the humerus, thereby improving the connection effect.

如图1至图3以及图9所示，在本实施例中，基体21上设置有插接柱211，连接块13上设置有插接孔131，插接柱211插入至插接孔131内，插接柱211和基体21之间设置有锁定件50。 上述的插接柱211插入至插接孔131内，并且基体21能够相对于连接块13发生转动，这样能够进一步实现调节。As shown in Fig. 1 to Fig. 3 and Fig. 9, in this embodiment, thebase body 21 is provided with a plug-inpost 211, and theconnection block 13 is provided with a plug-inhole 131, and the plug-inpost 211 is inserted into the plug-inhole 131 , A lockingmember 50 is provided between theinsertion post 211 and thebase body 21 . The above-mentionedinsertion post 211 is inserted into theinsertion hole 131 , and thebase body 21 can rotate relative to theconnection block 13 , so that further adjustment can be realized.

如图1至图3以及图9所示，在本实施例中，插接柱211为半球形结构，插接孔131为半球形凹部，半球形结构的直径等于半球形凹部的直径。半球形结构和半球形凹部的结构较为简单，并且能够实现摆动。具体地，在进行植入时，先通过插接柱211和插接孔131调节连接柄10和连接架20之间的角度，再通过螺钉锁定。这样使得半肘关节假体能够适配不同尺寸的骨骼。并且这样的调节方式较为简单，便于设置。半球形结构的直径等于半球形凹部的直径。As shown in FIG. 1 to FIG. 3 and FIG. 9 , in this embodiment, theinsertion post 211 is a hemispherical structure, theinsertion hole 131 is a hemispherical recess, and the diameter of the hemispherical structure is equal to the diameter of the hemispherical recess. The structures of the hemispherical structure and the hemispherical recess are relatively simple, and can realize swinging. Specifically, when implanting, the angle between the connectinghandle 10 and the connectingframe 20 is firstly adjusted through theinsertion post 211 and theinsertion hole 131, and then locked by screws. This allows the half-elbow prosthesis to fit bones of different sizes. Moreover, such an adjustment method is relatively simple and convenient for setting. The diameter of the hemispherical structure is equal to the diameter of the hemispherical recess.

连接块13上设置有多个第一连接孔，多个第一连接孔围设在插接孔131的外周，基体21上设置有多个第二连接孔，多个第二连接孔围设在插接柱211的外周，多个第一连接孔和多个第二连接孔对应设置，多个螺钉一一对应地插入至对应的第一连接孔和第二连接孔内。上述的多个第一连接孔和多个第二连接孔的设置能够实现固定基体21和连接块13。Theconnection block 13 is provided with a plurality of first connection holes, the plurality of first connection holes are arranged around the outer periphery of theinsertion hole 131, and thebase body 21 is provided with a plurality of second connection holes, and the plurality of second connection holes are arranged in the A plurality of first connection holes and a plurality of second connection holes are correspondingly arranged on the outer periphery of theinsertion post 211 , and a plurality of screws are inserted into the corresponding first connection holes and the second connection holes one by one. The arrangement of the above-mentioned multiple first connection holes and multiple second connection holes can realize the fixing of thebase body 21 and theconnection block 13 .

具体地，通过插接柱211和插接孔131实现角度调节后，通过多个螺钉依次连接在对应的第一连接孔和第二连接孔内，这样则实现了固定。Specifically, after the angle adjustment is realized through theinsertion post 211 and theinsertion hole 131 , a plurality of screws are sequentially connected in the corresponding first connection hole and the second connection hole, thus realizing the fixation.

需要说明的是，当角度调节后，存在对应的第一连接孔和第二连接孔错位，这样需要先通过多个螺钉穿入至不错位的对应的第一连接孔和第二连接孔内，即先实现粗连接，再通过螺钉将其余的对应的第一连接孔和第二连接孔连接。It should be noted that after the angle is adjusted, the corresponding first connection hole and the second connection hole are misaligned, so it is necessary to first pass a plurality of screws into the corresponding first connection hole and the second connection hole that are not misaligned. That is, the coarse connection is realized first, and then the remaining corresponding first connection holes and second connection holes are connected by screws.

错位的第一连接孔和第二连接孔的存在一定的重合部分。There is a certain overlap between the dislocated first connection hole and the second connection hole.

具体地，滑车部30与连接柄10之间实现微调是通过插接柱211和插接孔131：当需要调整左右方向时，调整左右2个螺钉的配合程度，当需要调整上下方向时，调整上下2个螺钉的配合程度，插接柱211能够插接孔131里转动，允许其上下左右调整位置，达到滑车部30微调的目的。Specifically, the fine adjustment between thepulley part 30 and the connectinghandle 10 is achieved through theinsertion post 211 and the insertion hole 131: when the left and right directions need to be adjusted, adjust the degree of cooperation between the left and right screws, and when the up and down directions need to be adjusted, adjust the According to the cooperation degree of the upper and lower 2 screws, theinsertion post 211 can rotate in theinsertion hole 131, allowing it to adjust its position up, down, left, and right, so as to achieve the purpose of fine-tuning thetackle portion 30.
