Clinical operation wire retractor fixing device suitable for neurosurgery department

Abstract

The invention discloses a clinical operation wire retractor fixing device suitable for the neurosurgery department. The clinical operation wire retractor fixing device comprises a fixed plate, a groove is formed in one end of the fixed plate, the side walls of the two sides of the groove are slidably connected with sliding blocks, a connecting plate is fixed between the sliding blocks, one end ofthe connecting plate extends to the exterior of the groove, a rotating disc is arranged above the connecting plate, the outer side wall of the rotating disc is connected with a plurality of adjustingwires, fixing hooks are fixed to the ends, away from the rotating disc, of the adjusting wires, the side wall of the bottom end of the groove is rotationally connected with a rotating shaft, one end of the rotating shaft extends to the exterior of the groove, and a rotating plate is fixed to the end of the rotating shaft; and a plurality of racks are formed on the side wall of the side, close to the rotating shaft, of the connecting plate, and the outer side wall of the rotating shaft is in a sleeved connection with a gear in a close fit mode. According to the clinical operation wire retractorfixing device, an operation wire tractor can be fixed, the problem of moving-back or vibration due to elastic force of a spring can be avoided, fixing stability is improved, the fixing range can be conveniently adjusted, the tensioning positions between the operation wire tractor and the fixing hooks can be adjusted, and fixing strength is improved.

Description

technical field [0001] The invention relates to the technical field of neurosurgery, in particular to a surgical retractor fixing device suitable for clinical neurosurgery. Background technique [0002] When the existing neurosurgery is performed, it is necessary to use retractors for surgical operations. Traditional retractor fixation methods often use springs and other methods to fix them. However, due to the spring itself has a certain elastic force, it is easy to cause a small amount of back movement during the pulling process. Or vibration, causing impact, for this reason, we have proposed a kind of surgical retractor fixation device applicable to clinical neurosurgery. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a clinically applicable neurosurgery hook fixation device. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: ...
