AI Technical Summary

Technical Problem

Traditional anterior cervical discectomy and fusion surgery suffers from limited visual depth, insufficient lighting, inconvenient operation, and surgeon's posture not conforming to ergonomics. Existing spinal endoscopy technology lacks supporting equipment, affecting surgical efficiency and safety.

Method used

An endoscopic working system for anterior cervical discectomy and fusion was designed, including an optical imaging system, an illumination system, and a mechanical system. The middle section of the endoscope handle can rotate 360°. Combined with image playback, the endoscopic field of view is expanded and the surgical area is clearly displayed.

Benefits of technology

It improves the safety and efficiency of surgical procedures, expands the endoscopic field of view, provides clear image display, reduces surgeon fatigue, and lowers the learning curve and equipment costs.

Abstract

The present application relates to the technical field of medical apparatus and instruments, and provides an endoscope working system for anterior cervical discectomy and fusion, which comprises an optical endoscope, a camera system, a spreader and a mirror holding arm; the optical endoscope comprises an optical imaging system, an illumination system and a mechanical system; the middle section of the handle of the optical endoscope can rotate freely around the inner tube by 360 degrees, the visual area thereof is trumpet-shaped, the trumpet-shaped opening of the visual area is arranged in a direction away from the inner tube, and the central axis of the visual area and the central axis of the inner tube form a certain angle. The beneficial effect is that the cost of the equipment used in the anterior cervical discectomy and fusion is greatly reduced; it should be pointed out that the endoscope working system can increase the visual field range under the endoscope in the case that the anatomical position under the endoscope remains unchanged, the image under the water medium is clearer, the light beam on the endoscope can rotate by 360 degrees, the obstruction to the surgical area is avoided, the surgical operation is facilitated, and the safety is higher.
