Wire saw guide device for total resection of spinal tumors

Abstract

The invention discloses a wire saw guide device for total resection of spinal tumors, and solves the problems of inconvenience of wire saw guidance caused by limitation of tools in conventional totalresection of spinal tumors, wherein the wire saw guide device comprises a guider with an arc-shaped structure, a guide channel for a wire saw to pass through is arranged inside the guider in the arc-shaped direction, and two ends of the guide channel extend out of the guider; the inner arc surface of the guider is provided with an incision in the arc-shaped direction, and the wire saw is separatedfrom the guide channel through the incision. The wire saw guide device with the structure can quickly and accurately guide the wire saw to an operation position, and protect the nerves and blood vessels of the spine while the wire saw is cut off, thereby reducing the operation risk.

Description

technical field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a guide for total spinal tumor resection. 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, due to the limitations of the anatomical structure of the spinal cord, it is impossible to completely resect the entire spine (including the spinal cord) during spinal tumor surgery, so the ring-shaped spinal structure must be cut off. From an anatomical point of view, the pedicle is the most suitable place...
