Abstract

The invention discloses a thoracic surgery retractor, which comprises an adjusting frame, a connecting rod, an end cover, a guide groove, a retraction cylinder, a screw rod, a guide rod, a fastening nut, a push-aside plate, a spring, a clamping seat, an elastic rope and a spring clip. Compared with the prior art, the thoracic surgery retractor of the invention has the advantages that the retraction cylinders can move and rotate freely on the adjusting frame, and different numbers of the retraction cylinders can be installed on the adjusting frame according to different using numbers of patients, so that the retraction position is easy and convenient to adjust; and after the retraction position is confirmed, the retractor can be locked through the fastening nut, the screw rod is slowly rotated to eject the push-aside plate out, ribs are expanded, and a plurality of expanders are matched together so as to provide an excellent operation view while the retractor can be evenly stressed when the ribs are expanded, so that and the situation that the retractor rotates, and consequently a patient is injured is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a retractor for thoracic surgery. Background technique [0002] Retractors, also known as retractors, are used to retract tissue to expose the area to be operated for easy exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. There are various specifications of different shapes and sizes, and the appropriate retractor can be selected according to the operation needs. [0003] Commonly used pull hooks are as follows: [0004] 1. Thyroid retractor is also called right-angle retractor, which is flat and hook-shaped. It is often used to stretch and expose the thyroid gland, and is also commonly used in other operations. It can retract skin, subcutaneous tissue, muscle and fascia, etc. [0005] 2. Abdominal retractors are also called square hooks, which are wide and smooth hooks, and are used for operations with lar...
