Abstract

The utility model provides a micro-trabecular biting cutter for the technical field of medical equipment. The utility model is mainly characterized in that a transition handle is additionally arranged between a handle, a biting cut mouth and a biting cut tongue. The line connecting direction of the transition handle and the biting cut mouth is provided with an acute angle relationship with the handle. The front end of the biting cut mouth adopts a trapezoid mouth. Compared with the prior art, the utility model has the obvious advantages of no influence on a visual field, large biting cut area at one time, etc.

Description

Micro-girder is stung and is cut device

This utility model belongs to technical field of medical instruments, is that a kind of micro-girder is stung and cut device.

At present the girder that uses in the ophthalmologic operation is stung and is cut device, and handle adopts staight shank, chews in the same way with stinging to cut, and the hands that the doctor operates this apparatus must have a strong impact on the art open country directly over it.The front end of meet mouth adopts the arc mouth, and this has just limited stings the scope of cutting and particularly can not enlarge the rear end, must repeatedly sting and cuts for reaching requirement sometimes.

The purpose of this utility model provides a kind of art open country that do not influence, and once stings the long-pending big girder of tangent plane and stings and cut device.

Technical solution adopted in the utility model is being stung on the basis of cutting device and can improved at original micro-girder, and at handle and sting to cut and chew, sting to cut and set up the transition handle between the tongue, the transition handle is cut the line direction of chewing with stinging, and has acute angle relation with handle; Sting the front end of cutting mouth and adopt trapezoidal mouth.

Because this utility model has been taked technique scheme, compared with prior art, having does not influence the art open country, once stings the long-pending big remarkable advantage that waits of tangent plane.

Below in conjunction with accompanying drawing and example specific structural features of the present utility model is described further.

Fig. 1 represents this utility model general assembly structural representation.

Fig. 2 represents this utility model general assembly side-looking structural representation.

As shown in Figure 1, the utlity model has to sting to cut mouth 1 and sting and cut tongue 2, both connect by two transition handles 3 respectively and 5, two transition handles 3 of preloading spring are set by rotating shaft 5 connections between 4, two handles 4 of two handles, sting to cut tongue 2 and be set in to sting and cut in the mouth 1.

As shown in Figure 2, transition handle 3 is chewed 1 line direction and handle 4 and is had acute angle relation with stinging to cut, promptly not point-blank.

Sting the scope of cutting for increase, sting the front end of cutting mouth and sting the front end of cutting tongue 2 and adopt trapezoidal.

Claims
