Problems solved by technology

[0006] The purpose of the present invention is to overcome the above disadvantages, to provide a hand clamping mechanism specially for thumb traction reset treatment, to solve the problem that in the prior art, the thumb and the other four fingers cannot be clamped separately, and the thumb and the other four fingers cannot be clamped. Refers to the technical problem that the clamping force cannot be adjusted according to the traction force due to different traction forces

Abstract

The invention relates to the technical field of medical instruments for fracture traction restoration, in particular to a hand clamping mechanism. The hand clamping mechanism comprises a T-shaped main fixing plate; the main fixing plate comprises a horizontal part, a longitudinal part, a first fixing plate, a second fixing plate, two symmetrical four-finger clamping part with a cavity for accommodating four fingers; the first fixing plate and the second fixing plate which are symmetrically arranged on the left side and the right side of the horizontal part; and the inner surface of a cavity of a thumb clamping part and the inner surface of the cavity of the four-finger clamping part are provided with flexible compressible layer for providing an interface with high fiction between the mechanism and skin of a patient. The hand clamping mechanism is specially used for thumb fracture traction restoration treatment, can respectively clamp the thumb and the other four fingers and provide different intensities of traction for the thumb and the other four fingers, and the clamping force of the hand clamping mechanism can be adjusted according to the traction force.

Description

technical field [0001] The invention relates to the technical field of fracture traction reduction medical equipment, in particular to a hand clamping mechanism for thumb traction. Background technique [0002] The treatment of fractures of the base of the first metacarpal bone usually includes two types of external fixation and internal fixation. External fixation includes external fixation with plaster tray, external fixation with external expansion board, and external fixation with various metal sheets. Local external fixation can stabilize the fracture. ; For comminuted fractures and fractures with subluxation of the carpometacarpal joint (i.e. Bennett's fracture), external fixation has poor curative effect and cannot correct the overlapping and angular displacement of the fracture ends, often resulting in malunion; internal fixation requires incision Reduction and fixation will leave incision scars and damage soft tissues such as periosteum; therefore, the treatment of ...
