Abstract

The utility model relates to a pair of intraocular forceps for fine ophthalmic surgeries. The utility model is provided with a pair of tubular handles and a pair of forceps claws. Each handle is provided with an operating handle. The thin casing tubes connected with the handles are in linkage with the handles through the sliding blocks and the springs in the handles, and the thin rod-shaped inner cores at the rear ends of the two forceps claws pass through the casing tubes and are fixedly connected with the handles. During use, when the handles are pressed by hands, the casing tubes move a definite distance toward the direction of the forceps claws, the two forceps claws close owing to the squeeze of the mouths of the tubes, and finally the forceps mouth is closed. When the hand moves away from the handles, the springs cause the casing tubes to reset, and the forceps mouth automatically opens. The forceps claws of the forceps are tiny and fine, and the handles are long, which brings convenience for grasping. The utility model has the advantage of convenient operation, and is suitable for fine ophthalmic surgeries.

Description

Ball inner tweezers for operation of ophthalmology

This utility model is a kind of ophthalmic forceps, tweezer in the ball that particularly trickle ophthalmologic operation is used.

Eye posterior surgical in the ophthalmologic operation all needs to carry out under trickle mirror as detachment of retina operation, operation on vitreous etc., and it is meticulous to perform the operation, and is the small tissue of tweezer ophthalmic, and existing typical ophthalmic surgical forceps can not be suitable for, needs the corresponding trickle surgical forceps of exploitation.

It is young and operate tweezer in the ball that nimble trickle ophthalmologic operation uses that the purpose of this utility model provides a kind of tweezer.

Tweezer has a tubular handle and a pair of tweezer pawl in this utility model ophthalmologic operation ball, handle is provided with operating grip, but a thin sleeve pipe that links with handle passes through interior sliding shoe of handle and spring and handle interlock and the axial stretching motion, the inner core of two tweezer pawl rear end thin rod shapes passes sleeve pipe, fixedlys connected with handle.When pushing handle, slide block compresses spring forward, promotes sleeve pipe and moves a certain distance to tweezer pawl direction, and two tweezer pawls are subjected to mouth of pipe extruding and close up, tweezer mouth closure, and during release handle, the elastic force of spring resets sleeve pipe, and the tweezer mouth opens automatically.

The tweezer pawl of tweezer is small and meticulous in this utility model ophthalmologic operation ball, and handle is longer, is convenient to hold, and tends to act by handle, and is easy to operate, is suitable for the small tissue of tweezer ophthalmic in the trickle ophthalmologic operation.

Below in conjunction with description of drawings structure of the present utility model.

Accompanying drawing is this utility model section of structure.

As shown, the tubular handle 3 of tweezer is provided with handle 6 in this ophthalmologic operation ball, and there is the inner core 4 of thin rod shape a pair of tweezer pawl 10 rear ends, inner core pass sleeve pipe 9 and by fastening block 1 and and tight screw 2 be tightly fixed with the inwall of handle 3 and be connected, make fixedly non-displacement of inner core.Sleeve pipe 9 and slide block 7 tight fits are connected with handle 6 by slide block, and the front end of slide block 7 is provided with spring 8, and the rear end of slide block is provided with regulates stop screw 5, be used to regulate and the displacement of limiting boot 9, thus the tweezer tightness of adjusting tweezer mouth.

Claims
