Surgical retractor for heart transplantation and using method thereof

Abstract

The invention discloses a surgical retractor for heart transplantation and a using method thereof, and relates to the technical field of medical instruments, in particular to a surgical retractor for heart transplantation. Thesurgical retractor comprises a retractor rod, a retractor box is clamped on the surface of the retractor rod, an adjusting box is fixedly connected to one end of the retractor rod, and a storage chamber is formed in the adjusting box. And a second lead screw is movably connected to an inner cavity of the storage chamber in a sleeving mode, and a second servo motor is fixedly mounted at the top of the adjusting box. According to the operation retractor for heart transplantation, through cooperative use of an adjusting box, a second lead screw, a first retractor body and a tooth-shaped connecting block, in the heart transplantation operation process, the thickness of the skin and fat of the thoracic cavity of a patient is observed firstly, and then the second servo motor is started to drive the second lead screw to rotate; and a first retractor is driven to move up and down through meshing transmission of the second lead screw and the tooth-shaped connecting block, the function of adjusting the length of the first retractor is achieved, and the stability of the surgical retractor for heart transplantation is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical retractor for heart transplantation and a method for using the same. Background technique [0002] Heart transplantation is mainly a surgical transplantation for advanced severe heart disease. During heart transplantation, the patient's chest cavity needs to be cut open, and the cut skin and fat are pulled apart by retractors so that doctors can operate on the heart. [0003] The Chinese invention patent with application number 201310169214.7 discloses a surgical retractor, which is composed of composite hook teeth, a slat handle and a reel handle. The composite hook teeth are arranged on the upper end of the slat handle, and the reel handle is arranged on The lower end of the slatted handle, the lower end of the slatted handle is connected with the reel handle in an inverted T shape. The compound hook teeth are composed of a row of teeth and a single tooth...
