Abstract

The invention discloses a surgical retractor for heart transplantation and a method for using the same, and relates to the technical field of medical devices, in particular to a surgical retractor for heart transplantation, including a retractor rod, a retractor box is snapped on the surface of the retractor rod, and the One end of the hook rod is fixedly connected with an adjustment box, and a storage room is opened inside the adjustment box, and a second screw rod is movably sleeved in the inner cavity of the storage room, and a second servo motor is fixedly installed on the top of the adjustment box . The retractor for heart transplantation is used in conjunction with the adjustment box, the second screw rod, the first retractor and the toothed connection block. During the heart transplant operation, first observe the thickness of the skin and fat of the patient's chest cavity, and then start the second The servo motor drives the second screw to rotate, and the meshing transmission between the second screw and the toothed connection block drives the first retractor to move up and down, realizing the function of adjusting the length of the first retractor and improving the stability of the surgical retractor for heart transplantation .

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.
