Abstract

The utility model relates to purse-string forceps used for an alimentary canal tube, which is composed of medical used handles and a forceps handle component connected with the medical used handles; and is characterized in that: the medical used handles include a left handle 2 and a right handle 3 which are in rotary connection by a fixed bolt 4; each of the two handles is provided with fixing clamping teeth 1; the fixing clamping teeth 1 on both handles are matched with each other; the forceps handle component connected with the medical used handles is composed of a left forceps handle 6 and a right forceps handle 5, and is arc shaped; the front end of each forces handle is provided with a noninvasive tooth profile combining clamping jaw 7 and a thread clamping groove 8. Compared with prior arts, the utility model has the following characteristics: the purse-string forceps is provided with a noninvasive tooth profile for combining clamping jaws and is convenient for drilling hole and positioning; can pierce tissues to enclose the tissues in different layers into a purse effectively, and is beneficial to the effective coalesce of the tissues after anastomosis; has a simple structure, and can relieve the suffering of a patient.

Description

Digestion deferent pocket pincers

One, technical field

This utility model belongs to medical instruments field, belongs to a class of medical anastomat, specially refers to a kind of digestion deferent pocket pincers that are used for Digestive System Department.

Two, background technology

In the simple and easy operation of medical science applied Digestive System Department, since the first seam nail series products of the invention sixties in 20th century, medical anastomat has become the requisite a kind of medical apparatus and instruments that aids in the tissue apposition process.Along with the development and the research and development of products of medical science, more and more multi-functional seam nail series products is applied to clinical.The scope of application has related to every field, becomes one of doctor's necessary tool.Thereby for the patient have less hemorrhage, less operating time in the art, with apparatus replace manual reduce because the manual error that causes, avoid infection, multiple advantage such as the postoperative function recovery is fast.For diffusion and the cross infection that prevents pathogenic bacteria, this class apparatus generally mostly is disposable use.Therefore high-quality anastomosis has become and guaranteed one of the successful key of performing the operation, and the high-quality of anastomosis has closely-related the contact with employed digestion deferent pocket wrench structure again.As main medical apparatus and instruments one of digestion deferent pocket pincers, be applied in a plurality of fields such as human body alimentary canal operation widely.It is local clearly inadequately to be specially adapted to operated interface portion bit comparison weak point or sight line, and these places will rely on above-mentioned digestion deferent pocket to clamp the intact stitching that realizes wound energetically.

Three, summary of the invention

This utility model technical issues that need to address are, in existing digestion deferent pocket pincers, in use yielding, often causing stitching nail only penetrates by the part level of seam when injected organism tissue, when tightening up pocket, easily cause purse wire fixing tight and come off,, provide a kind of digestion deferent pocket pincers in order to overcome this defective, it is made of medical handle and connected pincers handle assembly, it is characterized in that:

A, medical handle are made of left handle (2) and right handles (3), and are rotationally connected by set bolt (4), are provided with fixedly latch (1) on two handles, and the fixedly latch (1) on two handles cooperatively interacts;

B, the pincers handle assembly that is connected with medical handle clamp handle (6) and right pincers handles (5) formation by a left side, are the curved arc shape, and the front ends of two pincers handles are provided with involutory jaw of noinvasive flute profile (7) and clamp groove (8).

Involutory jaw of described noinvasive flute profile (7) and clamp groove (8) are structure as a whole, and are 60 ° with the bottom surface of clamping the handle assembly; The involutory jaw of wherein said noinvasive flute profile (7) is the curved arc shape, and its breach staggers each other; Wherein said clamp groove (8) is made up of teeth (9) and pinprick (10).

The characteristics that had mutually with prior art are:

1, sets up the convenient boring of the involutory jaw of noinvasive flute profile location;

2, will organize nail saturating, and make each layer tissue effectively be thrown into pocket, help being organized in the effectively healing of back that coincide;

3, have simple in structurely, can alleviate the advantage of patient's misery.

Four, description of drawings:

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is a side view of the present utility model.

Wherein 1, fixedly latch 2, left handle 3, right handles 4, set bolt 5, right claw beam 6, left claw beam 7, involutory jaw 8, clamp groove 9, teeth 10, pinprick

Five, specific embodiment:

Come the technical solution of the utility model is described further below in conjunction with attached Fig. 1 and 2.

A kind of digestion deferent pocket pincers described in the utility model, it is made of medical handle and connected pincers handle assembly, it is characterized in that:

A, medical handle are made of left handle 2 and right handles 3, and are rotationally connected by set bolt 4, and the fixedly latch 1 that is provided with on two handles on fixing 1, two handle of latch cooperatively interacts;

B, the pincers handle assembly that is connected with medical handle are made of left side pincers handle 6 and right pincers handle 5, are the curved arc shape, and the front end of two pincers handles is provided with involutory jaw 7 of noinvasive flute profile and clamp groove 8.

Involutory jaw 7 of described noinvasive flute profile and clamp groove 8 are structure as a whole, and are 60 ° with the bottom surface of clamping the handle assembly; The involutory jaw 7 of wherein said noinvasive flute profile is the curved arc shape, and its breach staggers each other; Wherein said clamp groove 8 is made up of teeth 9 and pinprick 10.

Because the digestion deferent is very smooth, by the curved arc shape, the involutory jaw 7 of noinvasive flute profile plays anti-skidding, location and stressed effect.

During use, finger inserts in the finger button of left handle 2 and right handles 3 one ends, about interlace, unclamp fixedly latch 1, and by set bolt 4 rotations handle 6 is clamped on a left side and open with right pincers handle 5, extend into the both sides of elongated tubular digestion deferent, this moment the curved arc shape, the involutory jaw 7 of noinvasive flute profile can be clamped elongated tubular digestion deferent easily, and the while chelating is latch 1 fixedly, left side pincers handle 6 and right pincers handle 5 are filled the span of a man's arms, involutory jaw 7 tightens up, and inserts corresponding breach, goes into the digestive tract pipe clamp therebetween, teeth 9 on the clamp groove 8 are bitten the tissue of a side simultaneously, to organize nail saturating by pinprick 10, and make each layer tissue effectively be thrown into pocket, help being organized in the effectively healing of back that coincide.

Threading or followed closely after, interlace about once more, unclamp fixedly latch 1, and rotate by set bolt 4 and handle 6 is clamped on a left side and right pincers handle 5 opens, extract out from elongated tubular digestion deferent both sides, finished sewing process to elongated tubular digestion deferent.

The above is the detailed description and the description of drawings of this utility model preferred embodiment; be not to be used for limiting this utility model; protection domain of the present utility model should be as the criterion with claim; the embodiment and the approximate construction of the spirit variation similar with it of every this patent protection domain all should be contained among this utility model.
