Description
Technical field
The invention belongs to ophthalmic operating set, relate to ophthalmology phacoemulsification microinstrument, relate in particular to a kind of cataract operation nucleus lentis eyelid retractor.Be applicable to phacoemulsification.
Background technology
Cataract is the first diseases causing blindness of the whole world and China, accounts for whole blinding patients' 45% left and right.Though cataract can not be prevented, can treat and recover vision by successful surgery.
Long ago it has been recognized that lenticular opacity generation cataract, stop that light enters 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) is to extract from ophthalmic complete muddy crystalline lens, because this art formula does not retain posterior capsulotomy, posterior chamber implantable intraocular lens difficulty, simultaneously to deviate from incidence rate high for vitreous body, easily causes vitreous hernia and cause the complication such as glaucoma, endothelial cell damage, cystoid macular edema and detachment of retina.Along with the progress of Ophthalimic microsurgery technology and the development of equipment, modern day cataract operation has obtained further development.ECCE (ECCE) is to extract muddy nucleus lentis and cortex part and the art formula that retains posterior capsulotomy, the complete reservation posterior capsulotomy of this operation, interference and destruction to intraocular structure are reduced, prevent 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, phacoemulsification (Phacoemulsification) reaches its maturity perfect.This operation applying ultrasonic energy will be absorbed after muddy nucleus lentis and Cortex Emulsification, retains posterior capsulotomy simultaneously, coordinates foldable artificial crystalline lens to implant, and successfully cures numerous cataract patients.The advantages such as it is short that phacoemulsification has the operating time, and otch is without stitching, and corneal astigmatism is little, and vision restoration is fast are the outer main flow cataract operation modes of Present Domestic.But cataract phacoemulsification art has requirements at the higher level to operator, especially for abecedarian or nucleus lentis person really up to the mark, the control of intraoperative ultrasound emulsifying energy is improper, and posterior capsular rupture easily occurs, and 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, while making in art posterior capsular rupture, can prevent that nucleus lentis piece from crashing into vitreous chamber, can complete smoothly again operation process 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 by injecting handle, inject pipe tail-hood, inject pipe, inject bar, spring, inject pipe cap, inject syringe needle and inject three-jaw and form.Inject pipe for hollow metal material, long 90mm, external diameter 10mm, one end embeds injects pipe tail-hood, the other end embeds injects pipe cap rear end, inject pipe cap front end tapered, inject pipe cap front inner diameter and inject syringe needle external diameter suitable (joining) mutually, injecting syringe needle is hollow metal material, external diameter 1mm, one end embeds injects pipe cap tapered front end, another port is from injecting pipe cap front end 15mm, injecting three-jaw passes in and out thus, injecting three-jaw is made up of three finer wires, every steel wire tail end with inject bar front end and fix, injecting three-jaw maximum, to stretch out the length of injecting syringe needle be 5mm, spring is placed on injects outside bar leading portion, inject bar stage casing diameter and to inject bore suitable mutually, inject bar stage casing diameter and be greater than leading portion and back segment diameter, inject handle and to inject bar tail end affixed.Injecting tube-surface is matrix anti-slip tank.
Feature of the present invention: 1. cataract operation nucleus lentis eyelid retractor is a kind of cataract phacoemulsification art para-operational device.There is posterior capsular rupture in cataract surgery process time, do not need to increase operative incision, the hand-held pipe of injecting of operator directly enters camera oculi anterior by the cornea side otch of setting up in phacoemulsification by injecting syringe needle, promotion is injected handle and is injected bar, in the time injecting handle and inject the coincidence of pipe tail-hood, injecting three-jaw stretches out by injecting syringe needle, become within the eye fan-shaped strutting, be positioned over nucleus lentis below, hold the core piece of wanting to fall, guarantee cataract phacoemulsification art is carried out smoothly.Operation finishes, and loosens and injects handle, by spring action, injects three-jaw and replys in injecting syringe needle, can exit from ophthalmic smoothly.
Cataract operation nucleus lentis eyelid retractor inject syringe needle, can be used as auxiliary hook and use, the effect such as core, rotation core piece is split in performance.3. reasonable in design of the present invention, simple for production, uses metal material, can autoclave sterilization, to reuse, and cost is low.
Brief description of the drawings
Fig. 1 is the cross-sectional view of three-jaw of the present invention while stretching out.
Cross-sectional view when Fig. 2 is three-jaw contraction of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment mono-
Referring to Fig. 1, a kind of cataract operation nucleus lentis eyelid retractor, this eyelid retractor by injecting handle 1, inject pipe tail-hood 2, inject pipe 3, inject bar 4, spring 5, inject pipe cap 6, inject syringe needle 7 and inject three-jaw 8 and form.Inject pipe 3 for hollow metal material, long 90mm, external diameter 10mm, one end embeds injects pipe tail-hood 2, the other end embeds injects pipe cap 6 rear ends, inject pipe cap 6 front ends tapered, inject pipe cap 6 front inner diameter and inject syringe needle 7 external diameters suitable (joining) mutually, inject syringe needle 7 for hollow metal material, external diameter 1mm, one end embeds injects pipe cap 6 tapered front end, another port is from injecting pipe cap 6 front end 15mm, injecting three-jaw 8 passes in and out thus, injecting three-jaw 8 is made up of three finer wires, every steel wire tail end with inject bar 4 front ends and fix, injecting three-jaw 8 maximums, to stretch out the length of injecting syringe needle 7 be 5mm, spring 5 is placed on injects outside bar 4 leading portions, inject bar 4 stage casing diameters and to inject pipe 3 internal diameters suitable mutually, inject bar 4 stage casing diameters and be greater than leading portion and back segment diameter, inject handle 1 and to inject bar 4 tail ends affixed.Inject pipe 3 surfaces and can design exasperate with anti-skidding, as be designed to matrix anti-slip tank.
Referring to Fig. 2, be that this eyelid retractor is injected three-jaw 8 and shunk back the structural representation while injecting syringe needle 7.
