Retractor device used in shoulder arthroscopy

Abstract

The invention belongs to the technical field of medical instruments, and relates to a retractor device used in shoulder arthroscopy, which comprises a main rod, an adjusting handle, a pull rod, a fixed connecting column, a sliding sleeve, a plurality of movable connecting rods and a plurality of movable claws, the adjusting handle is hinged to the upper portion of the main rod; the pull rod is hinged to the lower part of the adjusting handle; the fixed connecting column is connected to the bottom of the main rod, and the upper portion of each movable claw is hinged to the bottom of the fixed connecting column through a connecting column hinge ring. The sliding sleeve is sleeved on the connecting cylinder, and the upper part of the sliding sleeve is connected with the bottom of the pull rod; the upper portion of each movable connecting rod is hinged to the bottom of the sliding sleeve through a sleeve hinge ring, and the lower portion of each movable connecting rod is hinged to the outer side of the upper portion of each movable claw. The sliding sleeve moves on the fixed connecting column to enable the movable connecting rod to drive the movable claw to be opened and closed. The invention has the advantages that the operation of a surgical operator in the shoulder arthroscopy is facilitated, so that the optimal surgical effect is obtained.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a retractor device used in shoulder arthroscopy. Background technique [0002] With the rapid development of minimally invasive endoscopic technology in orthopedic clinics, more and more joint surgeons choose minimally invasive ways to deal with joint diseases. Due to the long learning curve and difficulty of shoulder arthroscopy, it has not been popularized and promoted in county-level hospitals across the country; and different from other orthopedic endoscopic techniques, good bleeding control and suture management are required during shoulder arthroscopy; whether it is The subacromial space is limited in either the beach chair position or the lateral position. After a long period of shoulder arthroscopic operation, due to the continuous infusion of a large amount of normal saline, extensive edema of soft tissues such as the deltoid muscle and synovial bursa will occur....
