Description

Transparent full-visual band light source working sleeve matched with spinal endoscope for use

Technical Field

The utility model relates to the technical field of medical surgical instruments, in particular to a transparent full-visible working sleeve with a light source, which is matched with a spinal endoscope for use.

Background

Along with the rapid development of minimally invasive techniques, spinal minimally invasive techniques represented by spinal endoscopes have been widely used clinically, and satisfactory therapeutic effects have been obtained. Compared with the traditional operation, the spine endoscope technology is a minimally invasive technology for developing earlier spine surgery, establishes a minimally invasive channel by means of a natural anatomical gap, relieves nerve compression, has less damage to paraspinal muscles, can keep the complete spine structure to the greatest extent, maintains the stability of the spine after operation, has the advantages of small trauma, less bleeding, quick recovery, less complications, definite curative effect and the like, and is a focus of attention and research in recent years.

Prior to treatment of spinal conditions, surgical incisions are first determined, a puncture cannula is used to access the desired surgical site, such as the spinal canal or intervertebral disc, a working channel is created by expanding the instrument step by step, and then the endoscope is inserted into the working channel for viewing and treatment. In the spinal endoscope operation, traditional working channel is mostly made of opaque metal materials such as stainless steel, only can observe the anatomy of the interior and the front end of the working sleeve in the clinical operation, and the region outside the working sleeve can not be observed, so that the whole understanding of the operation region by a clinical doctor is limited, and the prejudging of the next operation process by the operator can not be assisted. If the working sleeve has a transparent visual function, the observation area can be greatly expanded, and the operation safety and the operation efficiency are improved.

Second, conventional spinal endoscopes are typically integrated with working channels, optical systems, fiber optic illumination systems, irrigation channels, and the like. In the case of a spinal endoscope with a defined outer diameter, it is clinically desirable that the working channel be as large as possible in order to accommodate larger sized surgical instruments and to increase surgical efficiency. Because of the specificity of the spine operation, the outer diameter of the spine endoscope cannot be increased at will, and if the optical fiber illumination system can be stripped from the structure of the spine endoscope, the size of the working channel of the spine endoscope can be greatly increased, and the operation efficiency is further improved.
