Problems solved by technology

[0002] Clinically, the methods for treating metacarpal bone fractures are divided into non-surgical treatment and surgical treatment. Non-surgical treatment uses reduction splint or plaster for external fixation. The disadvantage is that the fracture is prone to displacement and recovery is slow; surgical treatment uses steel plates. Internal fixation requires a second operation to remove the plate, which causes pain to the patient and is prone to symptoms of radial bone shortening

Abstract

The invention belongs to the technical field of medical instruments and particularly relates to a finger metacarpal bone external fixation stent. The finger metacarpal bone external fixation stent comprises a connecting rod. The connecting rod is provided with a left needle rod clamp and a right needle rod clamp which can linearly slide within the preset travel range of the connecting rod along the connecting rod. The left needle rod clamp and the right needle rod clamp each clamp two needle rods. Locking devices are arranged at the positions, on the same sides of the left needle rod clamp and the right needle rod clamp, of the connecting rod. The finger metacarpal bone external fixation stent is simple and reasonable in structure, the metacarpal bone fracture portion is easily and reasonably fixed through effective operation, coalescence of the fracture portion is guaranteed, the fracture portion rapidly is restored to original functions and appearances, the exercise performance of a fixed portion is improved, operation simplicity and reliability are guaranteed on the premise of guaranteeing the treatment effect, the finger metacarpal bone external fixation stent is mainly used for treating the metacarpal bone fracture, and the correction and treatment effect of the fracture are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an external fixation bracket for metacarpal bones. Background technique [0002] Clinically, the methods for treating metacarpal bone fractures are divided into non-surgical treatment and surgical treatment. Non-surgical treatment uses reduction splint or plaster for external fixation. The disadvantage is that the fracture is prone to displacement and recovery is slow; surgical treatment uses steel plates. Internal fixation requires a second operation to remove the steel plate, which causes pain to the patient and is prone to symptoms of shortening of the radial bone. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a phalange-metacarpal bone external fixation bracket with a simple structure and reasonable design for treating fractures of the phalanx-metacarpal bones.
