Thoracic cavity expanding device based on thoracic surgery

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a thoracic cavity expanding device based on thoracic surgery, which comprises a casing, a first wedge-shaped block, a first wedge-shaped block, a movable wing blade and a propeller, an open movable groove is formed in the middle of the casing, and second wedge-shaped blocks are oppositely arranged on two sides of the first wedge-shaped block; the first wedge-shaped block and the second wedge-shaped block are arranged in the movable groove, the first wedge-shaped block pushes the second wedge-shaped block, the second wedge-shaped block is stressed to move transversely and used for retracting the chest to expose the view, the movable wing blade is fixed to the second wedge-shaped block and moves together with the second wedge-shaped block, and the propeller is used for pushing the first wedge-shaped block to slide. The first wedge-shaped block pushes the second wedge-shaped block to move, and meanwhile, the movable wing blades are linked to be opened in a back-to-back mode for limiting the visual field degree. The surgical retractor can be stably and smoothly moved to a required position, the tedious operation that a traditional handheld retractor is pulled open in a strenuous mode is abandoned, the range of surgical visual field expansion can be more accurately adjusted and controlled, and flexible adjustment of the visual field is achieved.
