An adjustable fracture reducer

Abstract

The invention discloses an adjustable fracture reducer, which comprises a first guide rod, a second guide rod and a first half-ring fixing plate. One side of the first guide rod is movably connected with a first half-ring fixing plate. One side of the ring fixing plate is movably connected with a second guide rod, the top of the first guide rod is connected with a first semi-circular needle seat, the bottom side of the first guide rod is movably connected with a second half ring fixing plate, and the second The top of the half-ring fixing plate is fixedly connected with the second semi-annular needle seat, and there is a needle seat chute inside the second half-annular needle seat. The user can rotate the nut to loosen the connection between the needle holder and the needle seat chute, and manually Move the needle holder to a fixed position, so that the needle holder moves in the needle seat slide groove, which is convenient for adjusting the insertion position of the needle. The connecting plate is vertically arranged in the middle of the half-arc plate, which is convenient for the user to follow the position of the connecting plate. Adjusting the angle of the needle holder is suitable for the use of fracture reduction, and has broad development prospects in the future.

Description

technical field [0001] The invention belongs to the field of orthopedic medical technology, in particular to an adjustable fracture reducer. Background technique [0002] At present, the clinical reduction of long tubular fractures is mainly through reduction and fixation after traction, and internal fixation in a stable state. The previous fracture reducer is mainly used for shortening and angular deformity. After reduction, it is difficult to stabilize and fix, and even affect internal fixation. The operation space in the entry process. [0003] Traditional fracture reduction techniques are generally closed reduction of the fracture site, and various techniques such as pulling and stretching, rotating flexion and extension lights are used, and most of them are controlled manually. The disadvantages such as difficulty in making fine adjustments make it impossible for the fracture segment to achieve anatomical reduction, what’s more, even the basic functional reduction cann...
