CN2610879Y - Snaked mouth type catarct suckion remover - Google Patents

Abstract

The utility model relates to a snake mouth like cataract aspirator, comprising a elastic wing, an upper cutting gear, a liquid aspirator port, a lower cutting gear, a pivot screw, an aspirator pipe body, a pipe body tail and a liquid outlet port, characterized in that the integrated elastic wing and the upper cutting gear, the integrated lower cutting gear and the aspirator pipe body, and the pipe body tail are connected with each other through the pivot screw, and the middle edges of the upper cutting gear and the lower cutting gear cave to form the aspirator port. The utility model is manually operated, resolving the problem that instruments' entering the anterior chamber for multiple times tend to damage the endothelial cells and the lens posterior capsule. The snake mouth like cataract aspirator relates to simple manufacture process, easy usage and high effectiveness, and can be applied to the aspiration of cataracts.

Description

Snaked mouth type cataract suckion remover

This utility model relates to medical instruments field, is a kind of snaked mouth type eyes cataract suckion remover.

Existing cataract fragmentation nucleus tweezer fragmentation nucleus technology has and repeatedly enters the eyes anterior chamber, easy damaged endothelial cell and posterior lens capsule film, the difficult anterior chamber depth that forms, the low deficiency that waits of efficient.

This utility model provide a kind of by last cutting and following cutting sting cut the cataract crystal nuclear after, by suckion remover body and drain pipe crystal nuclear and the external cataract suckion remover of lens cortex sucking-off, free-hand operation during use, efficient is higher, have and in operating process, keep anterior chamber depth, advantages such as less damage endothelial cell and posterior lens capsule film.

This utility model is achieved in that

Snaked mouth type cataract suckion remover is made up of elasticity wing, upward cutting, liquid sucting port, cutting down, fulcrum screw, suckion remover body, body afterbody, liquid outlet, and the elasticity wing that wherein is made into integration is connected by the fulcrum screw with suckion remover body, body afterbody with the following cutting that is made into integration with last cutting.

This cataract suckion remover has following characteristics and good effect:

1, because of being the cavity of a closure between last cutting and the following cutting, so, when absorbing eyes lens cortex and crystal nuclear, very little to eyes endothelial cell, posterior lens capsule membrane damage.

2, because of last cutting, down cutting stinging of crystal nuclear cut is to carry out in the eyes anterior chamber, and the crystal nuclear that is bitten away is external by the direct sucking-off of foot suction apparatus immediately, and the number of times that this will reduce suckion remover turnover anterior chamber alleviates the damage to eye inner tissue, simultaneously also will shorten operating time, efficient is higher.

3, the manufacturing process that relates to of the design is simple, and manufacturing cost is lower, is easy to produce, and simultaneously, easy operating is believed the use interest that can improve user.

Below in conjunction with accompanying drawing this utility model is further described:

Accompanying drawing 1 is a front elevation of the present utility model.

Accompanying drawing 2 is a vertical view of the present utility model.

Accompanying drawing 3 is a left view of the present utility model.

Accompanying drawing 4 is a right view of the present utility model.

Accompanying drawing 5 is debugging figure of the present utility model.

Elasticity wing 1 and last cutting 2 are made into integration, form the upper body part, to descend cutting 4, suckion remover body 6, body afterbody 7 to be made into integration, form the lower body part, upper body part and lower body partly be connected into a complete snaked mouth type cataract suckion remover by fulcrum screw 5.

During debugging, body afterbody 7 is connected with drain pipe 14 1 ends, the other end of drain pipe 14 is connected with electric suction apparatus 15, the portion of chewing of the snaked mouth type cataract suckion remover 13 under the closure state main otch by schematic eye 12 is entered the anterior chamber, crystal auxiliary needle 11 enters the anterior chamber by auxiliary incision, with light finger compression elasticity wing 1 top, the last cutting 2 that fuses is upwards dehisced, contain crystal nuclear, when unclamping elasticity wing 1 top, the last cutting 2 that fuses will be closed downwards under elastic reaction, and sting and downcut the fritter crystal nuclear, the foot switch 17 of pedal and electric suction pump 15 can make the fluid of crystal auxiliary needle 11 suck suckion remover body 6 by liquid sucting port 3, and the sucking-off of fritter crystal nuclear is external; So repeatable operation can all be absorbed crystal nuclear and cortex clean.

In the accompanying drawing 1,8 is liquid outlet, and in the accompanying drawing 5,9 is liquid, and 10 is woven hose, and 16 is lead.

Claims (2)

1, a kind of snaked mouth type cataract suckion remover, form by elasticity wing, upward cutting, liquid sucting port, cutting down, fulcrum screw, suckion remover body, body afterbody, liquid outlet, wherein elasticity wing and last cutting are integral production, form the upper body part, following cutting and suckion remover body, body afterbody integral production, form the lower body part, the upper body part partly is connected by the fulcrum screw with lower body; It is characterized in that the elasticity wing 1 that is made into integration is connected by fulcrum screw 5 with suckion remover body 6, body afterbody 7 with the following cutting 4 that is made into integration with last cutting 2.

2, snaked mouth type cataract suckion remover according to claim 1 is characterized in that head makes Serpentis mouth shape, and last cutting 2 is caved in into liquid sucting port 3 with following cutting 4 in center edge.
