Description

Finger ring type polisher

Technical Field

The utility model relates to a polisher technical field specifically is ring type polisher.

Background

Cataract means that the lens in the eyeball is turbid, changes from transparent to opaque and blocks light from entering the eye, thereby affecting vision, the early stage turbidity does not affect the vision when being slight or in a small range, and then gradually aggravates to obviously affect the vision and even blindness. Currently, phacoemulsification is an internationally recognized advanced cataract treatment method with the characteristics of small incision, small wound, quick recovery and the like, and the operation is carried out in two steps, namely, the turbid crystal is removed in the first step, and the artificial crystal is implanted in the second step.

Firstly, making an incision of 1.8mm-3mm on the eye, inserting a phacoemulsification needle by a doctor through the small incision to divide the turbid and hardened crystalline lens into small pieces to become chylomid liquid, sucking out the small pieces in a negative pressure suction mode, injecting viscoelastic agent into anterior chamber, filling the capsular bag, inserting traditional polisher into the capsular bag from side incision, scraping epithelial cells on anterior capsular sac, mechanically rubbing the surface of posterior capsular sac, polishing the back capsular sac, finally extending the I/A syringe needle into the capsular sac through the main incision, the polished epithelial cells and residual cortex are sucked out by means of negative pressure suction or directly polished under the anterior capsule by an I/A syringe needle after the residual cortex is sucked out, but the main incision is edematous, and the astigmatism is increased.

The existing polisher can only polish and cannot suck out the polished epithelial cells and residual cortex.

For this reason, we propose a ring-type polisher to well solve the above drawbacks.
