AI Technical Summary

Technical Problem

In current ophthalmic surgeries, conventional lighting instruments are difficult to precisely adjust the illumination area, and the incision size and invasiveness are relatively large, affecting the surgical outcome.

Method used

A microsurgical instrument has been designed, comprising an optical fiber and a guiding mechanism. The optical fiber has an adjustable pre-shaped bend. Axial movement and radial orientation adjustment of the distal end of the optical fiber can be achieved by operating an actuating component and a rod. When used in conjunction with a cannula, it provides focused or diffused light illumination.

Benefits of technology

It enables precise light illumination of the inner part of the eye, reducing incision size and invasiveness, and improving the visualization and flexibility of the surgery.

Abstract

A microsurgical instrument for illuminating an internal site includes an optical fiber having a length between opposing proximal and distal ends, where the proximal end of the optical fiber is configured for operative engagement with an illumination light source, where the distal end of the optical fiber includes a light emitting portion, a pre-formed curved portion of the optical fiber proximate the distal end, where the optical fiber has a curved portion. The optical fiber includes a curved portion having a predetermined bend or curve, a flexible tubular sleeve enclosing at least a portion of the optical fiber, where the tubular sleeve has a preformed curved portion corresponding to the curved portion of the optical fiber.
