Embodiment

[0031] This embodiment provides a bone platform drilling device, such as Figure 1-3 As shown, it includes: a punching nail 1, including a main body portion 11, and a punching portion 12 fixedly connected to one end of the main body portion 11, the outer diameter of the punching portion 12 is smaller than the outer diameter of the main body portion 11, The junction of the main body portion 11 and the perforated portion 12 forms a stepped surface 13; the guide plate 2 includes a plate body 21, and several through holes 22 uniformly arranged on the plate body 21, the through holes 22 The inner diameter of the hole can only allow the perforated portion 12 to pass through, the length of the perforated portion 12 is greater than the depth of the through hole 22, and the maximum length that the perforated portion 12 can extend after passing through the through hole 22, That is the target drilling depth.

Abstract

The invention provides a bone platform perforating device. The device comprises a perforating nail and a guide plate, wherein the perforating nail comprises a main body part and a perforating part which is fixedly connected with one end of the main body part, the outer diameter of the perforating part is less than that of the main body part, and the joint of the main body part and the perforating part forms a stepped surface; the guide plate comprises a plate body and a plurality of through holes which are uniformly arranged in the plate body, the inner diameters of the through holes can only allow the perforating part to pass, the length of the perforating part is greater than the depths of the through holes, and the maximum length that the perforating part can stretch after passing through the through holes is a target perforation depth. The perforating device provided by the invention has the following advantages: firstly, the perforating depth can be accurately controlled, so that the pouring effect of bone cement is guaranteed; and secondly, the perforating density can be accurately controlled, so that the problem that the connective firmness is not uniform as the perforating position uniformity is not enough can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of tools for joint replacement, in particular to a bone platform drilling device. Background technique [0002] The joint is the hub of human movement. Due to trauma or degeneration, severe knee joint pain, joint deformity, and dysfunction may occur. At this time, artificial knee replacement surgery is required. In order to firmly fix the joint prosthesis, it is necessary to apply bone cement to the femur, the tibial osteotomy surface, the inner surface of the femoral prosthesis, and the lower surface of the tibial prosthesis. After the bone cement hardens, a firm connection between the human joint and the prosthesis can be achieved. Due to joint degeneration, the articular surface of the tibia is hardened, and it is difficult for the bone cement to penetrate into the cancellous bone of the tibia and cannot be fixed firmly. . [0003] In the current joint replacement surgical instruments, since there is no...
