Wire saw guide for total resection of spinal tumors

Abstract

The invention provides a wire saw guide for total resection of spinal tumors, comprising a guide passage (1) and a core (2); the guide passage (1) is of arc bend structure, and the inner side of the arc structure is provided with an opening from the head of the guide passage (1) to its tail; the core (2) is slidably disposed in the guide passage (1), and one end of the core (9) close to the head of the guide passage (1) is provided with a hooking device (21) to be connected with a wire saw. By guiding a threaded wire saw to safely and efficiently run through the front of vertebrae, the risk of injuring vascular nerves in process of using the threaded wire saw to resect vertebrae is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a wire saw guide used for total resection of spinal tumors. Background technique [0002] In recent years, with the study of tumor theory, the improvement of tumor staging system and the improvement of surgical techniques, fundamental changes have taken place in the treatment of spinal tumors. En bloc total spondylectomy has the advantages of being able to completely remove the tumor tissue, effectively reducing the contamination of the tumor to surrounding tissues, reducing the recurrence rate of the tumor, and significantly improving the survival rate of patients. However, in the case of en bloc total spondylectomy, the surgical tools currently used for this procedure are not well established. Thread saws also have unavoidable surgical risks in the process of passing through the front of the vertebral body and cutting the vertebral body, such as damaging the large bloo...

However, in the case of en bloc total spondylectomy, the surgical tools currently used for this procedure are not well developed

The thread saw also has unavoidable surgical risks in the process of passing through the front of the vertebral body and cutting the vertebral body, such as damaging the large blood vessels and nerves in the front of the vertebral body.
