Description

A kind of needle forceps

Technical field

This utility model relates to a kind of needle forceps, is mainly used in the intravital suture operation of human body in the laparoscopic surgery, belongs to technical field of medical instruments.

Background technology

In the human body body in the laparoscopic procedures, in case find focus in the human body body, need excision, otch needs to sew up, and in operation process, the needle forceps of prior art does not satisfy ideal surgical effect, its defective is: needle forceps chuck steel quality is low, structural design is unreasonable, and it is unreasonable especially to clamp functional structure, easily causes needle roller.Cause trouble and use inconvenience for the medical operating personnel, also can bring misery to patient.

Summary of the invention

Technical problem to be solved in the utility model provides the needle forceps of a kind of reasonable in design, easy to use, the good clamping effect of operation, operation safety.

It is this needle forceps that this utility model solves the problems of the technologies described above the technical scheme that is adopted, its construction features is: be made up of handle, rocking arm, draw-bar seat, rest pad, pull bar, claw beam, fixed pliers head, movable binding clip, guide pipe, flush-through connection, described handle is two, be respectively arranged with the lock tooth on two handles, two lock teeth match each other; The end of handle is connected with rest pad by hinge screws, and handle also links to each other with an end of rocking arm by the rocking arm connecting pin, and the other end of rocking arm links to each other with draw-bar seat by connecting pin, and draw-bar seat links to each other with pull bar; Be respectively arranged with guide pipe and claw beam at the two ends of described rest pad, described pull bar passes guide pipe and claw beam, and pull bar links to each other with movable binding clip, and the end of claw beam is provided with fixed pliers head, and movable binding clip and fixed pliers head are provided with the folder tooth that matches each other; On rest pad, also be provided with flush-through connection.

Be provided with sealing ring between claw beam described in the utility model, guide pipe and the rest pad.

Fixed pliers head described in the utility model, movable binding clip are bending

This utility model is compared with prior art and is had the following advantages and effect: 1, structural design of the present utility model, as long as hold handle with a firm grip, two rocking arms pull back draw-bar seat, under the effect of two lock teeth, it is tightly pinned, and movable binding clip and fixed pliers head are stung mutually tightly, and binding clip is stung tight sewing needle, under the effect of folder tooth with its pinning, thereby guaranteed clamping stability and firm degree.2, the binding clip applying flexible that is bending, in application process, binding clip is stung tight sewing needle, can arbitrarily not come off, and also can arbitrarily not wear and tear long service life.3, designed flush-through connection, and design there is sealing ring, can injects in the claw beam with disinfectant solution, flushing residual liquid sterilization, under the effect of sealing ring, residual liquid can not flow into handle part; Folder pin stitching clamp is that metal is made, and also can use high-temperature sterilization.
