Tissue retractor applied to spinal surgery

Abstract

The invention discloses a tissue retractor applied to spinal surgery. The tissue retractor comprises a movable base, a supporting frame, a height adjusting mechanism, two retraction plates and a retraction mechanism. The supporting frame is fixed to the top of the movable base, and a first box body is fixed to the supporting frame through a connecting frame arranged on the side wall; the height adjusting mechanism is arranged in the first box body, the output end of the height adjusting mechanism extends below the first box body and is connected with a second box body, and a through opening is formed in the bottom of the second box body; the two retraction plates are vertically and symmetrically arranged below the second box body; the retracting mechanism is arranged in the second box body, and one ends of the two retracting plates extend into the through opening to be connected with the output end of the retracting mechanism. During an operation, the height of the traction plates can be adjusted through the height adjusting mechanism, the opening angle of the two traction plates can be adjusted through the traction mechanism, medical staff can conveniently perform operative treatment on the injured spine part of a patient, a doctor can conveniently place screws, the exposed view of the affected part can be increased, and the operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tissue retractor applied to spinal surgery. Background technique [0002] Posterior spinal surgery is an important approach for the treatment of spinal fractures, spondylolisthesis and other spinal diseases. The exposure of the articular process and transverse process is very important for locating the pedicle entry point. In order to fully expose the surgical field of view, it is often necessary to A retractor is used for exposure. [0003] Existing retractors are relatively simple and have a single function. Most of them use an elastic metal sheet to hold the two ends of the metal sheet on the skin at the operation site, thereby realizing the retraction of the skin and tissue. However, in the actual operation process Among them, because the patient's body size is different, so the height and angle of retraction are different, the height of the existing retractor ...

Problems solved by technology

[0003] Existing retractors are relatively simple and have a single function. Most of them use an elastic metal sheet to hold the two ends of the metal sheet on the skin at the operation site, thereby realizing the retraction of the skin and tissue. However, in the actual operation process In this case, due to the different sizes of patients, the height and angle of retraction are different. The height and angle of the existing retractor plate cannot be adjusted quickly according to the needs, which is not conducive to the operation.
