AI Technical Summary

Technical Problem

In current double eyelid surgery techniques, inaccurate conjunctival positioning leads to asymmetry in the width, height, and curvature of the double eyelid, affecting the surgical outcome.

Method used

A conjunctival locator for double eyelid surgery is designed, which adopts a sliding and adjustable hollow needle and a grouped groove structure to achieve millimeter-level overlap between the conjunctival locating point and the outer marking line. The hollow needle is fixed by a rotating groove, which supports standardized needle placement for multiple locating points.

Benefits of technology

It achieves precise and symmetrical conjunctival positioning, solves the problems of asymmetry in double eyelid width, crease height, and curvature, shortens operation time, and improves surgical quality.

Abstract

This utility model relates to the field of surgical instrument technology and discloses a conjunctival locator for suture-based double eyelid surgery. It includes: a first clamp body comprising a first ring portion, a first clamp rod, and an upper plate; the upper plate has evenly distributed grooves, within which a hollow needle is provided, which can slide along the grooves to adjust its position; the hollow needle has a hollow structure; a second clamp body comprising a second ring portion, a second clamp rod, and a lower pad; the second end of the second clamp rod has the lower pad; the first clamp rod and the second clamp rod are hinged, and the lower pad cooperates with the upper plate. This utility model can solve the problem of inaccurate conjunctival positioning and can adjust the width of the double eyelid according to the patient's requirements. It greatly shortens the operation time and allows even inexperienced surgeons to quickly create high-quality suture-based double eyelids.
