Abstract

The invention relates to the field of medical instruments, and discloses a support reductor for treating tibial plateau fracture, which comprises a screw rod (1), a sleeve (2), a first Kirschner wire (3), a second Kirschner wire (4), a first joint fixing ring (5), a second joint fixing ring (6), and a collar (7), wherein the sleeve (2) is internally provided with a plurality of pawls; the surface of the screw rod (1) is provided with trapezoidal thread; the tail end of the screw rod (1) is fixed in the collar (7); the front-end trapezoidal thread is clamped on the pawls; the first joint fixing ring (5) is connected to the tail end of the sleeve (2) via a mobile connection rod (8); and the second joint fixing ring (6) is connected to the tail end of the screw rod (1) via the mobile connection rod (8). The support reductor for treating the tibial plateau fracture is particularly suitable for traction reduction for both tibial fracture dislocation and fibula fracture dislocation, and has the advantages of simple structure, low cost, convenient operation, and flexible adjustment.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a support resetter for treating tibial plateau fractures. Background technique [0002] At present, the treatment of articular surface collapse of tibial plateau fractures mostly uses periosteal strippers, screwdrivers, etc. for reduction. There is no ideal reduction tool. The existing technology has the following technical problems. The reduction time is long and inaccurate, which brings great harm to patients. Unnecessary pain. Contents of the invention [0003] The invention provides a support reducer for treating tibial plateau fractures, which solves the technical problems of long reset time and inaccuracy of the support reducer for tibial plateau fractures in the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A support reducer for treating tibial plateau fractures, including: screw 1, sleeve 2, firs...
