Abstract

The invention relates to the technical field of medical instruments, in particular to an adjustable osteotomy guider. The guider mainly comprises an osteotomy plate, an adjusting plate connected to the upper side of the osteotomy plate in a sliding mode in the front-back direction, a femur fixing nail for fixedly connecting the adjusting plate to the osteotomy face of the distal femur, and an adjusting assembly for connecting the osteotomy plate and the adjusting plate. The osteotomy plate is provided with a plurality of osteotomy grooves penetrating through the upper side and the lower side;the adjusting plate is provided with a long hole extending in the left-right direction; the adjusting assembly comprises an adjusting knob and an eccentric connecting piece; the lower end of the adjusting knob is fixedly connected with the upper end of the eccentric connecting piece; the adjusting knob and the eccentric connecting piece are eccentrically arranged; the adjusting knob penetrates through the upper side and the lower side of the osteotomy plate; the eccentric connecting piece is arranged in the long hole of the adjusting plate in a penetrating mode; and the eccentric connecting piece is matched with the adjusting knob to clamp the osteotomy plate and the adjusting plate together. The osteotomy guider has the effect of conveniently adjusting the osteotomy amount.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to an adjustable osteotomy guide. Background technique [0002] The knee joint is one of the most complex joints in the human body, and it is also an important load-bearing joint of the lower limbs of the human body. Due to accidents, bad exercise habits, diseases and other reasons, many patients have varying degrees of damage to their knee joints, making life extremely inconvenient. Among them, the knee joint function of some patients can be restored through knee joint replacement surgery. [0003] In knee joint replacement surgery, especially total knee joint replacement surgery, it is necessary to perform multiple osteotomies on the distal femur 1 so that the shape of the osteotomy surface matches the shape of the prosthesis 2 to be implanted. refer to figure 1 and figure 2 , in order to improve the accuracy of the shape of the osteotomy surface, the osteotomy proces...
