Abstract
The utility model relates to forceps used in ophthalmic surgery, which is characterized in that an angle (3) of 90 degrees which bends inward is arranged in the position 3.5mm far away from the front end of a forceps handle (1); in addition, an angle (2) of 135 degrees which bends outward is arranged in the position 100mm far away from the angle (3) of 90 degrees. In this way, the utility model can clamp the upper rectus effectively and avoid the reverse operations in a common operation; while drawing the upper rectus, the gap between the upper rectus and the sclera will increase and the utility model can measure the distance from the cornea edge to the end of the upper rectus. After the inclination between the front end of the forceps handle and the nipper handle is set to be 135 degrees, the utility model can increase the movement radius and movement range greatly.
Description
Technical field: this utility model relates to medical apparatus and instruments, specifically a kind of ophthalmologic operation tweezers.
Background technology: at present, the tweezers of the fixedly superior rectus that ophthalmologic operation is used, because the gripping part is 130 ° of angles with tweezer handle front end, and length is too short, and the counter-rotating action when having increased operation like this makes the gap between superior rectus and the sclera too little when the traction superior rectus, difficulty when seizing the superior rectus attachment point on both sides by the arms, if blindly seize on both sides by the arms and cause easily that conjunctiva is torn, conjunctiva hematoma or be not stitched to the tram, increase patient's misery, and do not reach the fixedly purpose of eyeball.
Summary of the invention: the purpose of this utility model is to provide a kind of novel ophthalmologic operation tweezers, uses easy to operately, helps reaching surgical effect, improves operative speed.The technical solution of the utility model is: a kind of novel tweezers is characterized in that: the 90 ° of angles that curve inwardly at distance tweezer handle front end 3.5mm place, and at distance outwardly-bent 135 ° of angles, 90 ° of bent angle 10mm places.This utility model is owing to the 90 ° of angles that curve inwardly at distance tweezer handle front end 3.5mm place, and at distance outwardly-bent 135 ° of angles, 90 ° of bent angle 10mm places, can seize superior rectus effectively on both sides by the arms, avoided the counter-rotating action of routine operation, during the traction superior rectus, the gap between superior rectus and the sclera is increased, can hold concurrently and survey the distance of limbus of corneae to the superior rectus not-go-end, after the angle of tweezer handle front end and tweezer handle is set as 135 ° of angles, radius of action and range of activity have been increased greatly.
Description of drawings: accompanying drawing is a structural representation of the present utility model.
The specific embodiment: this utility model is further described below in conjunction with accompanying drawing.
The front end of this utility model one tweezer handle (1) is provided with groove or salient point, corresponding with the salient point or the groove of the front end of another tweezer handle (1), and the 90 ° of angles (3) that curve inwardly at distance tweezer handle (1) front end 3.5mm place, then, at distance 90 ° of bent angles (3) outwardly-bent 135 ° of angles, 10mm place (2), like this, during use, when having avoided the counter-rotating action traction superior rectus of routine operation, gap between superior rectus and the sclera is increased, also can hold concurrently simultaneously and survey the distance of limbus of corneae to the superior rectus not-go-end, the angle of tweezer handle front end and tweezer handle is set as 135 ° of angles after, increased radius of action and range of activity greatly.
