AI Technical Summary

Technical Problem

Existing endoscopes require a large radial dimension for their instrument channels to accommodate large surgical instruments, resulting in high endoscope costs and reduced adaptability, as well as insufficient precision and intuitiveness of ultrasound-guided systems.

Method used

An endoscope with an integrated cutting device is designed. The outer wall of the endoscope tube is provided with a guide groove and a connecting part. The cutting part is slidable and the driving part drives the cutting part to move back and forth. Combined with a detachable structure and an angle-adjustable imaging element, it can achieve small radial size and high-precision surgery.

Benefits of technology

This has resulted in a reduction in the radial size of the endoscope, improving the precision and applicability of surgery, reducing costs, and providing better visual feedback and operational comfort.

Abstract

The application relates to an endoscope integrated with a cutting device, which comprises an operating part, a mirror tube, a head end and the cutting device. The mirror tube is provided with a guide groove, and a connecting part of the cutting device is slidingly arranged in the guide groove. The endoscope further comprises a transmission part, a distal end of which is connected to an imaging element; the body of the head end has a receiving cavity, and the imaging element is rotatably arranged in the receiving cavity around a first rotating shaft; the transmission part drives the imaging element to rotate when the transmission part moves; a proximal end of the transmission part is connected to a driving part of the cutting device, so that the driving part drives the cutting part to simultaneously drive the transmission part to adjust the angle of the imaging element, and the angle of the imaging element is matched with the position of the cutting part. An illuminating element arranged in the receiving cavity can also be rotatably arranged. The driving part of the cutting device can be a handle or a knob or a micro motor provided with a transmission mechanism. The linkage of the cutting device and the imaging element or the illuminating element can realize better visual feedback in surgery.
