Abstract
A pair of bursa ripping forceps for cataract operation is provided, which belongs to the medical appliance, and comprises a left and a right forceps claw (1 and 2), the upper ends of which are connected with each other and the lower ends of which are bent in the same direction and are in elastic patulous. The utility model is characterized in that flutes (5 and 6), which can indicate the size of the bursa ripping, are independently or simultaneously positioned on the curve reaches (3 and 4) at the lower end of the left and right forceps claws (1 and 2). The utility model, which solves the blind bursa ripping problem in the operation, has the advantages of simple structure, convenient manufacturing and operation accuracy enhancement.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of ophthalmologic operation apparatus, specifically a kind of cataract ultrasonic emulsification operation Tweezers for eye surgery.
Background technology
As everyone knows, cataract ultrasonic emulsification associating artificial intraocular lenses implantation is the cataractous routine operation method for the treatment of at present.Needing in the operation with Tweezers for eye surgery capsule before crystalline to be done a diameter is continuous curvilinear capsulotomy about 5.5～6mm, so that form the crystalline capsule bag of implantable artificial after ultrasonic emulsification.Middle sizeable curvilinear capsulorhexis is steady in a long-term extremely important to implantable artificial crystal position.For senior operative doctor, can control the size of tearing capsule by rule of thumb, tear capsule and finish as object of reference with the big back pupil that looses in the operation usually for the abecedarian.Because patient's pupil diameter difference is bigger, therefore be prone to the oversize or too small phenomenon of curvilinear capsulorhexis in the actual operation, influence surgical effect.
Summary of the invention
The purpose of this utility model is the time not have reference index at utilizing Tweezers for eye surgery to tear the capsule operation in the cataract operation, needs to seek object of reference by rule of thumb or in addition and operates, and the problem that accuracy is bigger designs a kind of cataract hands that has scale mark and states and use Tweezers for eye surgery.
The technical solution of the utility model is:
A kind of cataract operation Tweezers for eye surgery, comprise left and right tweezer pawl 1,2, the upper end of left and right tweezer pawl 1,2 links to each other, their lower end is crooked in the same way and be elasticity and open shape, it is characterized in that being provided with individually or simultaneously on the bending section 3,4 of described left and right tweezer pawl 1,2 lower ends a signable groove 5,6 that tears the capsule size.
Described groove 5,6 is 5.5～6 millimeters from the distance at pawl point 7,8 places of left and right tweezer pawl 1,2.
The beneficial effects of the utility model:
Utilizing Tweezers for eye surgery of the present utility model to stretch into patient's glasses anterior chamber prepares when tearing capsule and can do one relatively by the scale on the observation tweezer point and with the size of pupil, help estimating to tear the size of capsule, reduce the blindness of operation, help the rapid raising of abecedarian's operation level, improve medical level.
In addition, the utlity model has simple in structurely, make or improve advantage easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described.
As shown in Figure 1.
A kind of cataract operation Tweezers for eye surgery, comprise the left and right tweezer pawl 1,2 of medical stainless steel, the upper end of left and right tweezer pawl 1,2 links to each other, their lower end is crooked in the same way and be elasticity and open shape, at the upper surface of the bending section 3,4 of described left and right tweezer pawl 1,2 lower ends simultaneously or be provided with a signable groove 5,6 that tears the capsule size separately.This groove 5,6 in 5.5～6 millimeter, is a master scale with 6 millimeters from the distance of the tweezer point of the left and right tweezer pawl 1,2 of correspondence wherein, also can be provided with simultaneously.
This utility model does not relate to the part prior art that maybe can adopt same as the prior art to be realized.
Claims (2)
