Abstract

Extraction forceps for tumor operations comprise two jaws (2) and two forceps handles (5), wherein the two forceps handles (5) are fixedly connected to each other through a pin (3); the outer side of the tail end of each of the forceps handles (5) is provided with a griping ring (6); the inner side of the tail end of each of the forceps handles (5) is provided with a sawtooth fastener (4); top ends of the two jaws (2) are respectively provided with a grappler (1) which is bent inwards; and the plane of the grappler (1) is perpendicular to that of the two jaws (2). The grapplers have large points of strength, and are capable of firmly grapple tumor tissues to lead the tumor tissues not easy to slip off, accordingly normal running of operation and operation effect are guaranteed. Besides, the grapplers are properly arranged, and effectively fix the jaws, and facilitate operation of medical workers.

Description

A kind of tumor operation extracts pincers

Technical field

This utility model relates to a kind of surgical oncology medical surgical instrument field, is specifically related to a kind of tumor operation and extracts pincers.

Background technology

Have now in the tumor operation process, usually need to stretch into and take out tumor tissues in the body cavity with hands, but, this method needs bigger operative incision, and because tumor tissues is more sliding, grab than being easier to slippage, usually need repeatedly several times with hands, easily cause the wound of body surrounding tissue, strengthened the probability that infection and other complication take place.

The Chinese patent publication number is CN201216628, the utility model description that open day is on April 8th, 2009 discloses " a kind of tumor operation special vice ", this utility model is buckled and is formed by Qianer, protruding nail, tong arm, grip circle, tooth, it is characterized in that described Qianer is the semicircle arcuation, Qianer is provided with protruding nail, and tong arm is connected with Qianer, and the end of tong arm is provided with the grip circle, the grip circle is provided with tooth and buckles, and two tong arms are connected as a single entity by staple.When implementing tumor operation, the tumor operation pincers are stretched into patient abdominal cavity affected part, according to the size of tumor, buckle the Zhang Du of control Qianer with the tooth on the grip circle, make protruding nail on the Qianer catch the tumor soma of easy slip, after making it to be maintained fixed state, excision again undergos surgery.Compare with the traditional tumour ablation technique, this utility model has that the corrective surgery of making otch is little, and the tumor grapple is firm, and is easy to use, and patient's wound healing is fast, reduces characteristics such as ailing and medical expense.But this utility model is when grasping tumor, and impetus is too small, can puncture the tumor body, causes tumor tissues slippage in the operation process, has influenced surgical effect.

The utility model content

The purpose of this utility model is to grasp deficiencies such as impetus is too small, the easy slippage of tumor at existing tumor operation special vice, provides that a kind of extracting impetus is big, the not eely tumor operation of tumor tissues extracts pincers.

The purpose of this utility model realizes by following technological means: a kind of tumor operation extracts pincers, include two binding clips and two pincers handles that are connected setting by dowel fixes, the terminal arranged outside circle of shaking hands of pincers handle, the inboard then is provided with the sawtooth button, the top of described two binding clips is respectively arranged with an aduncate grapple, the plane at described grapple place be set to the binding clip vertical direction on.

Described grapple is set to aduncate semicircular arc.

The inner fovea part of described grapple also is provided with concavo-convex body.

Compared with prior art the utlity model has following tangible advantage: the grapple impetus that this tumor operation extracts pincers is big, can catch tumor tissues firmly, makes it be difficult for slippage, has guaranteed normally carrying out and surgical effect of operation; It is suitable that the grapple of this tumor operation extraction pincers is provided with, and regular jaw is effective, makes things convenient for medical worker's operation technique.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure, the 1-grapple, the 2-binding clip, the 3-pin, 4-sawtooth button, 5-clamps handle, the 6-circle of shaking hands.

The specific embodiment

Below in conjunction with the description of drawings and the specific embodiment this utility model is described in further detail:

A kind of tumor operation as shown in Figure 1 extracts pincers, include two binding clips 2 and fixedly connected the pincers handle 5 of setting by pin 3 with two, the terminal arranged outside of pincers handle 5 is shaken hands and is enclosed 6, the inboard then is provided with sawtooth button 4, the top of described two binding clips 2 is respectively arranged with an aduncate grapple 1, the plane at described grapple 1 place be set to binding clip 2 vertical direction on.Described grapple 1 is set to aduncate semicircular arc.Be provided with like this, grapple 1 impetus that this tumor operation extracts pincers is big, can catch tumor tissues firmly, makes it be difficult for slippage, has guaranteed normally carrying out and surgical effect of operation.

The inner fovea part of described grapple 1 also is provided with concavo-convex body.Be provided with like this, further increased the area of putting forth effort of grapple 1, increased frictional force, strengthened the extracting effect.

This tumor operation extracts pincers in use, its head is probeed into intraperitoneal, and the grapple 1 open size by the folding and the open angle of sawtooth button 4 are adjusted jaw penetrates or catches the tumor soma that will excise with grapple 1, soma mentions with tumor, and then finishes resection operation.

In a word, this utility model provides that a kind of extracting impetus is big, the not eely tumor operation of tumor tissues extracts pincers.The above; it only is a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.

Claims
