AI Technical Summary

Technical Problem

The traditional endoscopic transparent cap structure cannot be deformed, resulting in small effect on improving the visual field of endoscopic observation, poor manipulation, limited degree of fixation of lesion tissue, and complex surgical operations.

Method used

An endoscopic transparent cap is designed, including an endoscopic joint, auxiliary pulling member, radial expansion member and driving member. The radial expansion and rotation of the clip are achieved by driving the tendon, and the radial size of the cap is adjusted to assist in pulling the lesion tissue.

Benefits of technology

Significantly improve endoscopic field of vision, improve operation convenience, simplify surgical operations, and enhance the fixation and hemostasis of lesion tissue.

Abstract

The invention discloses an endoscope transparent cap which comprises an endoscope connector, an auxiliary traction component, a radial expansion component, a guide pipe and a driving component. The endoscope connector is used for being connected with an endoscope in a sleeved mode, the radial expansion component is arranged at the far end of the endoscope connector, a plurality of installation bases in the auxiliary traction component are distributed in the circumferential direction of the far end of the radial expansion component, and a plurality of clamping pieces are hinged to the installation bases respectively. The driving part is arranged at the near end of the endoscope, the radial expansion part and the clamping piece are in transmission connection with the driving part through the first driving tendon and the second driving tendon respectively, the guide pipe is arranged on the peripheral wall of the endoscope, and at least part of the driving tendon penetrates through the guide pipe; the driving part is configured to drive the radial expansion part to be folded or expanded in the radial direction of the endoscope connector by pulling or releasing the first driving tendon, and can drive the clamping pieces to rotate inwards or outwards in the radial direction by pulling or releasing the second driving tendon. When the transparent cap for the endoscope is applied, the visual field of the endoscope can be improved to a great extent, the operation convenience of the endoscope is improved, and the surgical operation is simplified.
