Description

A kind of Multifunctional cataract surgical assistor

Technical field

The utility model relates to a kind of Multifunctional cataract surgical assistors.

Background technique

Cataract is important diseases causing blindness, and the origin cause of formation is lenticular muddiness.Mature cataract mainly passes through operation and controls It treats, modus operandi is mainly and passes through to extract muddy crystal nuclear and cortex at present, retains crystal pouch, and implantable artificial crystal. When wound or congenital reason cause crystal suspensorium to be broken, it may appear that Crystal and Ligand field even complete dislocation, serious crystal Dislocation needs to pass through operative treatment.Since the tension that pouch lacks suspensorium is supported, operating difficulty increases, relative to simple white interior Barrier is extractd, and auxiliary instrument is needed to support.

Previous Crystal and Ligand field mainly makes its stabilization using capsular retractors drawing lens capsule bag.The modus operandi needs volume Multiple corneal incisions are done outside, be easy to cause additional corneal injury, increase operating time and infection risk.And capsular retractors are by high score Sub- polymer manufacture is easy loss deformation by autoclave sterilization repeatedly and loses.Capsular retractors when crystal pouch overtension Itself is also easy sliced crystal pouch, and capsule splits before making, and greatly increases art risk.

Moreover, need to inject viscoelastic agent to supplement viscoelastic agent in art from lateral incision, other instrument is needed to pass in and out eye repeatedly It is interior, so that anterior chamber is unstable, easily increase intraoperative compliaction and postoperative infection risk.

In addition, crystal, which splits core, needs special chop tool auxiliary, lens capsule residual cortex polishing needs to change special Polishing tool, a variety of auxiliary tools are easy to cause subluxation posterior lens capsule to be easy to spring up, and being easily sucked by super nipple negative pressure causes Poster capsulorhexis generates severe complication.
