Abstract

The invention discloses an orthopaedic sternum retractor with a radian adjustable structure, relates to the technical field of retractors, and solves the problems that an existing pincerlike retractor can only transversely open the skin in parallel and has few application conditions. The orthopedic sternum retractor with the radian-adjustable structure comprises a retraction hook, the middle of the retracting hook is rotationally connected to the outer ends of bottom connecting rods, and the top of the retracting hook is rotationally connected to the outer ends of top connecting rods. When the retractor is used, the opening form can be freely changed, so that the skin can be transversely opened or opened in a V shape by taking a bone as a support, the retractor can adapt to traction opening operation on the skin under any treatment condition, the retractor is convenient and flexible to use, and the flexibility and the practicability of the retractor are improved.

Description

technical field [0001] The invention belongs to the technical field of retractors, and more specifically relates to an orthopedic sternal retractor with an adjustable arc structure. Background technique [0002] Retractors, also known as retractors, are used to retract tissues to expose the area to be operated on and facilitate 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. In various thoracotomy operations in thoracic and cardiothoracic surgery, in order to facilitate the medical staff to see the specific situation in the patient's thorax more comprehensively, a sternal retractor is needed to expand the medical staff's treatment field of view. [0003] For example, in the patent with the application number: CN201811548973.3, a left atrial appendage retractor and an auxi...
