Specimen extractor for thoracic cavity minimally invasive surgery

Abstract

The invention discloses a specimen extractor for thoracic cavity minimally invasive surgery. The invention belongs to the technical field of medical instruments. The specimen extractor includes an outer rod, wherein a front end table is fixed at one end of the outer rod; a grabbing structure is fixed at the other end of the outer rod; a hollow cavity is formed in the outer rod; a core rod is installed in the hollow cavity, a bag wire is connected to the end, close to the front end table, of the core rod, a specimen bag is connected to the side, away from the core rod, of the bag wire; an adjusting structure is connected to the end, close to the grabbing structure, of the core rod, and the outer rod is elastically connected with the adjusting structure through a spring. By means of the adjusting structure, the adjusting button, the sliding groove, the sliding block and the magnetic strip are arranged, wherein the fixing structure is provided with the arc-shaped fixing plate, the abutting groove and the magnetic block, various structures are matched with one another, the adjusted core rod can be fixed, manual fixing of medical staff is not needed, and therefore the medical staff cantake out the core rod conveniently, and market competitiveness is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a specimen extractor for minimally invasive thoracic surgery. Background technique [0002] Minimally invasive thoracic surgery is a new technique of minimally invasive thoracic surgery that uses modern camera technology and high-tech surgical equipment to complete complex intrathoracic surgery under a chest wall cannula or tiny incision.
