Spinal surgery connecting rod imbedding auxiliary drag hook

Abstract

The invention discloses a spinal surgery connecting rod imbedding auxiliary drag hook which comprises a U-shaped plate, a hook is arranged above the U-shaped plate, a fastener is arranged on the U-shaped plate, the U-shaped plate is fixedly installed on the side edge of a sickbed through the fastener, a supporting frame and an installation rod are arranged above the U-shaped plate, the hook is movably installed on the installation rod. Compared with the prior art, the spinal operation connecting rod imbedding auxiliary drag hook has the advantages that the elastic connecting piece is arranged, the hook can tightly hook muscular tissue through the reset elastic force of the connecting spring, and the connecting spring can be prevented from rapidly rebounding in the rebounding process through matched use of the spiral rod and the spiral sleeve; injury to a wound of a patient is avoided, the height of the hook can be adjusted during use by arranging the supporting piece, the hook is suitable for patients of different body types, muscle tissue can be pulled open at a time by arranging the opening piece, the connecting rod can be conveniently placed in, and the time of medical staff is saved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary drag hook for placing a connecting rod in spinal surgery. Background technique [0002] In spinal surgery, after multiple pedicle screws are implanted, connecting rod linking screws need to be placed, but the musculature around the nails will affect the insertion of the connecting rod, so retractors are needed to pull the muscular tissue apart to obtain surgery. vision. [0003] The existing retractor is a single individual, which needs to be used in multiples. During the operation, it is not only necessary to hook the muscle tissue in sequence, but also to pull it manually. This method is labor-intensive and has low reliability. It is also more complicated to make the hook hook the musculature. For this reason, we propose a spinal surgery connecting rod placement auxiliary retractor. Contents of the invention [0004] The object of the present invention...
