Medical coracoid excision device

Abstract

The invention discloses a medical coracoid resection device, which solves the problems that in the prior art, coracoid resection operation is difficult, and surrounding tissue is prone to being damaged, the operation can conduct smooth, accurate and controllable resection on coracoid, and can effectively protect peripheral nerves, muscles and vascular tissue. According to the technical scheme, themedical coracoid resection device comprises a wire saw, protection plates and guide assemblies, the guide assemblies are fixed to the inner sides of the protection plates, the protection plates are symmetrically arranged on the two sides of the wire saw, the wire saw penetrates through the guide assemblies, and the wire saw located between the protection plates can form an obtuse angle through the guide assemblies.

Description

technical field [0001] The invention relates to the field of surgical tools, in particular to a medical coracoid process resection device. Background technique [0002] The coracoid process is a hard bony protrusion on the mandible that is completely composed of cortical bone. It is located deep and is surrounded by important nerves, large blood vessels and other tissues. A powerful temporalis muscle is attached to the coracoid process. When the temporalis muscle contracts, the coracoid process pulls the mandible upward and rotates backward to realize the movement of closing the mouth. During the opening movement, the temporalis muscle relaxes and the coracoid process rotates forward. If the forward movement of the coracoid process is limited due to various reasons such as trauma and tumor, the opening will be restricted. [0003] In order to treat the limited opening, coracoid process resection is a commonly used operation in clinic, often performed alone or in combinatio...

AI Technical Summary

Problems solved by technology

The disadvantage is that because the coracoid process is extremely hard and the position is deep, the force direction of the osteotome can only be perpendicular to the long axis of the coracoid process, so two kinds of complications often occur. The strong impact force caused mandibular fractures and damage to important nerves, muscles, and blood vessels around the coracoid process
