The supporter has reasonable design, is simple and convenient to manufacture, adopts metal materials, can be disinfected at high temperature and high pressure, can be used repeatedly, and is low in cost.
Description
Technical field
The invention belongs to ophthalmic operating set, relate to ophthalmology ultrasonic emulsification cataract operation microinstrument, relate in particular to a kind of cataract operation nucleus lentis eyelid retractor.Be applicable to ultrasonic emulsification cataract absorption operation.
Background technology
Cataract is the first diseases causing blindness of the whole world and China, accounts for whole blinding patients' about 45%.Though cataract can not be prevented, can successfully treat through performing the operation and recover vision.
Long ago it has been recognized that lenticular opacity generation cataract, stop that light gets into ophthalmic, extract muddy crystalline lens, can effectively improve and recover vision.Just there were the record of couching for cataract in China and India before more than 1,000 year.And the intracapsular cataract extraction in modern age (ICCE) to be crystalline lens with muddiness complete extracts from ophthalmic; Because this art formula does not keep the posterior lens capsule film; Posterior chamber implantable intraocular lens difficulty; Simultaneously vitreous body is deviate from the incidence rate height, is prone to cause vitreous hernia and causes complication such as glaucoma, endothelial cell damage, CME and detachment of retina.Along with Ophthalimic microsurgery development of technology and Equipment of Development, the modern day cataract operation has obtained further development.ECCE (ECCE) is to extract the nucleus lentis of muddiness and the art formula that cortex partly keeps the posterior lens capsule film; This complete reservation posterior lens capsule film of performing the operation; Interference and destruction have been reduced to intraocular structure; Prevented the complication that vitreous body is deviate from and caused, created conditions for smooth posterior chamber implantable intraocular lens simultaneously.Since the sixties in last century, ultrasonic emulsification cataract is absorbed operation (Phacoemulsification) and is reached its maturity perfect.This surgical application ultrasonic energy is absorbed after with muddy nucleus lentis and cortex emulsifying, keeps the posterior lens capsule film simultaneously, cooperates the foldable artificial crystalline lens to implant, and successfully cures numerous cataract patients.Advantages such as ultrasonic emulsification cataract is absorbed operation and had the operating time weak point, and otch need not to sew up, and corneal astigmatism is little, and vision restoration is fast are current domestic and international main flow cataract operation modes.Yet ultrasonic emulsification cataract is absorbed art operator there are requirements at the higher level; Especially for abecedarian or nucleus lentis person really up to the mark; The control of intraoperative ultrasound emulsifying energy is improper, and the posterior lens capsule film rupture takes place easily, and the nucleus lentis piece crashes into vitreous chamber and causes a series of severe complications.Therefore be necessary to invent a kind of operating theater instruments, when making in art the posterior lens capsule film rupture, can prevent that the nucleus lentis piece from crashing into vitreous chamber, can accomplish operation process smoothly again simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of cataract operation nucleus lentis eyelid retractor, this eyelid retractor is by injecting handle, inject the pipe tail-hood, inject pipe, inject bar, spring, injecting pipe cap, inject syringe needle and inject three-jaw and constitute.Inject pipe and be the hollow metal material, long 90mm, external diameter 10mm, an end embed and inject the pipe tail-hood; The other end embeds injects the pipe cap rear end, and it is tapered to inject the pipe cap front end, injects the pipe cap front inner diameter and injects syringe needle external diameter right (joining) mutually; Injecting syringe needle is the hollow metal material, and external diameter 1mm, an end embed and inject the pipe cap tapered front end; The another port is injected three-jaw and is passed in and out thus from injecting pipe cap front end 15mm, injects three-jaw and is made up of three finer wires; Every steel wire tail end with inject the bar front end and fix, injecting the three-jaw maximum, to stretch out the length of injecting syringe needle be 5mm, spring is placed in injects outside the bar leading portion; Inject bar stage casing diameter and fit mutually, inject bar stage casing diameter, inject handle and inject the bar tail end affixed greater than leading portion and back segment diameter with injecting bore.Injecting tube-surface is the matrix anti-slip tank.
Characteristics of the present invention: 1. cataract operation nucleus lentis eyelid retractor is that a kind of ultrasonic emulsification cataract is absorbed the art para-operational device.In when, in the ultrasonic emulsification operation process posterior lens capsule film rupture taking place; Need not increase operative incision, operator is hand-held injects pipe and will inject syringe needle and directly absorb the cornea side otch of setting up in the operation through ultrasonic emulsification cataract and get into camera oculi anterior, injects handle and injects bar; When injecting handle and injecting the coincidence of pipe tail-hood; Inject three-jaw and stretch out, become fan-shaped within the eye and strut, be positioned over the nucleus lentis below through injecting syringe needle; Hold the nuclear piece of desiring to fall, the assurance ultrasonic emulsification cataract is absorbed art and is carried out smoothly.Operation finishes, and loosens and injects handle, through spring action, injects three-jaw and replys in injecting syringe needle, can withdraw from from ophthalmic smoothly.
Cataract operation nucleus lentis eyelid retractor inject syringe needle, can be used as auxiliary hook and use, nuclear is split in performance, effects such as piece are examined in rotation.3. reasonable in design of the present invention, simple for production, use metal material, but autoclave sterilization, repeated use, cost is low.
