Problems solved by technology

However, when the doctor finished the osteotomy of the distal femur and was about to carry out the next operation, he found that the distal femur still needs to be cut. At this time, the positioning pin fixing the distal osteotomy guide has been removed, and the doctor cannot accurately find the original bone. At this time, the distal femur will need to be repositioned, which is very troublesome and has low positioning accuracy.

Embodiment Construction

[0035] Contraction below Figure 1-4 Further detailed description of the present application.

[0036] The present application example discloses a distalbed bone apparatus. Refer figure 1 The femoral distal juncture instrument includes a guide 1 and a helper positioning handle 2 that is detachable on the guide 1.

[0037] Refer figure 1 However, there is a plurality of staple holes 11 on the guide 1, and the first blade groove 12 is also opened on the guide 1, and the guide 1 is placed directly on the side wall of the distal end of the femur 3, and The guide pin of the distal end of the femur 3 can pass through the nail hole 11, and then the cutter can be cut into the distal end of the femur 3 through the cutter from the first knife groove 12, and the interceptment is completed.

[0038] Refer figure 2 The nail hole 11 is provided with two groups, and the two sets of staple holes 11 are opened at both ends of the guide 1, and the position of the guiding device 1 can be fixed to rea...

Abstract

The invention relates to a distal femur osteotomy instrument and relates to the field of medical instruments. The distal femur osteotomy instrument comprises a guider and an auxiliary positioning handle detachably connected to the guider, wherein a nail hole is formed in the guider; the nail hole penetrates through the upper side and the lower side of the guider; a first knife groove is formed in the guider; the auxiliary positioning handle comprises an insertion piece; and the insertion piece is matched with the first knife groove in an inserted mode. The instrument has the effects that the distal femur can be repositioned conveniently, and the positioning precision is improved.

Description

Technical field [0001] The present application relates to the field of medical devices, in particular, relates to a distalbutant device. Background technique [0002] During the femur of the knee joint, the femur is usually used by the distal end of the bone. One surface of the interposer is bonded to femur, and the hoste is achieved through the hood on the chef. [0003] The existing femurial intercepted methods are nail holes that design different sizes on the distal junction guide, and changes in the amount of femoral bones are achieved by adjusting the position of the nail holes. However, when the doctor is completed by the distal bone of the femur, it will be necessary to perform the next operation, and find that the femur needs to be intercepted, while the positioning pin of the fixed distal junction guide has been removed, the doctor can't find the original The nail hole, which will need to be repositioned in the distal femur, positioning is very troublesome, and the posit...
