Peripheral iris microscopic nipper pliers for peripheral iridectomy of department of ophthalmology

Abstract

The invention provides peripheral iris microscopic nipper pliers for peripheral iridectomy of department of ophthalmology, and relates to the technical field of medical devices. The peripheral iris microscopic nipper pliers comprise a first tip end, a second tip end, a connecting part, a left handle, a right handle, a spring and a spring connecting part, wherein a first cutout is formed in the topend of the first tip end and is a curved sharp cutout, a second cutout is formed in the top end of the second tip end and is a curved shape cutout, the first tip end is connected with the upper end of the left handle, the second tip end is connected with the upper end of the right handle, the left handle and the right handle are hinged through the connecting part, one end of the spring is fixed to the right handle, the right handle is connected with the spring through the spring connecting part, and the other end of the spring is fixed to the left handle. After the technical scheme is adopted, the peripheral iris microscopic nipper pliers have the beneficial effects of being effortless in clamping, and convenient for surgery operations, and the peripheral iris microscopic nipper pliers have the advantages that the peripheral iris microscopic nipper pliers can be repeatedly used, and bleeding during pressurizing can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a microscopic needle-nose pliers for cutting iris around the eye. Background technique [0002] In ophthalmic vitrectomy surgery, for complex fundus surgery, the vitreous cavity often needs to be filled with silicone oil as a substitute for the vitreous body to restore the detached retina. For eyes with aphakia, due to the communication between the anterior and posterior chambers, after silicone oil filling, the silicone oil is easy to enter the anterior chamber due to the position and gravity, and the angle of the chamber is filled with silicone oil, blocking the outflow of aqueous humor, causing secondary high intraocular pressure. Clinically, in order to prevent silicone oil from entering the anterior chamber, a peripheral incision is often made at the root of the iris at six points below to form a communication opening. After operation, the prone position is used ...

AI Technical Summary

Problems solved by technology

However, when the vitrectomy head is used for iris peritomy, each person’s experience and techniques are different, so different shapes are often cut out, and the cutting suction is not well controlled, which may easily cause the peripheral incision to be too large or too small, resulting in double pupils and pupil displacement. , or even resection of large blood vessels, causing secondary anterior chamber hemorrhage, the probability of reocclusion of the peripheral incision is high
