Abstract

The utility model discloses a minimally invasive knife which comprises a knife blade, wherein the knife blade is connected with a handle through a knife bar, the knife blade is round, a half circumference of the knife blade is a knife back and the other half circumference of the knife blade is a cutting edge. The outside surface of the knife bar is tangential to the circumference of the knife back, and the inside surface of the knife bar is intersected with the circumference of the cutting edge. The cross section of the circumferential part of the knife back is arc-shaped. The cross section of the handle is round. Rough patterns are arranged on the outer side of the handle. With the structure, the minimally invasive knife has reasonable structure, minimizes the injury to the normal tissue, is applied to various minimally invasive operations and helps to increase the operation success rate.

Description

A kind of Wicresoft cutter

Technical field

This utility model relates to a kind of Wicresoft cutter.

Background technology

Scalpel generally is divided into two kinds, small needle knife and general surgery cutter.Small needle knife, as the term suggests be exactly the scalpel that cutter head is narrow, knife bar is elongated, small needle knife generally uses in Minimally Invasive Surgery, can reduce wound face, avoid other normal structures are caused damage, the small needle knife that uses generally comprises blade at present, blade links together by knife bar and handle, the blade of blade is a vertial knife edge, to make things convenient for fly-cutting, because the said structure characteristics of small needle knife, cut sufferer when organizing, still there is the hidden danger of scuffing, incised wound normal structure in the two ends of blade, influence cutter under the doctor, and what be unfavorable for performing the operation normally carries out.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of a kind of Wicresoft cutter rational in infrastructure, less to other normal tissue injuries at above-mentioned deficiency.

For solving the problems of the technologies described above, this Wicresoft cutter comprises blade, and blade links together by knife bar and handle, and its construction features is: blade is rounded, and half circumference of blade is the knife back, and half circumference in addition of blade is a blade.

It is less when Wicresoft's cutter of this structure is realized performing the operation by circular transition structure to other normal tissue injuries.Circular transition structure is meant that whole insert design is circular, a half cycle of blade is as the knife back, another half cycle of blade is as blade, in the middle of just presenting, the blade part of whole blade protrudes forward, and two ends circular-arc to after-contraction, like this, when carrying out the sufferer cutting tissue, the middle part that blade protrudes forward will at first contact sufferer tissue or normal structure, and the blade two ends are because be positioned at rear, blade middle part, may reducing greatly of contact sufferer tissue or normal structure, when therefore using this Wicresoft cutter to undergo surgery, the blade middle part of protrusion gets final product only to need to descend the cutter center of gravity to be placed on forward, is convenient to the doctor in charge and attentively descends cutter and clean cut, can effectively avoid other normal structures are caused damage, help improving the success rate of Minimally Invasive Surgery.

As a kind of implementation, knife bar lateral surface and knife back circumference are tangent, and knife bar medial surface and blade circumference intersect.

Knife bar lateral surface and knife back circumference is tangent, knife bar medial surface and blade circumference are intersected, and like this, the blade part of blade just has been arranged on the inboard of knife bar, and blade knife back portion just with tangent being connected as a single entity in the knife bar outside, when entering patient's disease sites when holding a sword in one's hand, the knife back can be against in the patient linked groups to the front slide feed, because the knife back is a circular arc, and the knife back is tangent with knife bar again, therefore not only slotting tool is smooth, and can not cause damage to linked groups, helps improving operation efficient.

As improvement, the cross section of knife back circumferential part is arcuation.

The cross section of knife back circumferential part is arranged to arcuation, can further strengthens the slick and sly degree of the knife back, when slotting tool, can effectively protect linked groups not to be scratched.

As further improvement, the handle cross section is circular.

The handle cross-sectional area is designed to circle, and when operation, the blade direction is adjusted more easily, can be handling stronger.

As further improving, the handle outside is provided with numb stricture of vagina again.

Turning handle is provided with numb stricture of vagina in the handle outside for convenience, skids in the time of can effectively preventing rotary handle, and is convenient when adjusting insert orientation.

In sum, adopt Wicresoft's cutter of this structure, rational in infrastructure, less to other normal tissue injuries, be adapted at using in the various Minimally Invasive Surgerys, help to improve success rate of operation.

Description of drawings

In conjunction with the accompanying drawings this utility model is described in further details:

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

Fig. 2 is the left view of Fig. 1.

Among the figure: 1 is blade, and 2 is knife bar, and 3 is handle, and 4 is blade, and 5 is numb stricture of vagina, and 6 is the knife back.

The specific embodiment

As shown in Figure 1, be structural representation of the present utility model, this Wicresoft's cutter comprises blade 1, and blade 1 is rounded, and half circumference of blade 1 is the knife back 6, and half circumference in addition of blade 1 is a blade 4.Blade 1 is fixed in left side, knife bar 2 upper ends, that is to say that knife bar 2 lateral surface and the knife back 6 circumference are tangent, and knife bar 2 medial surface and blade 4 circumference intersect.Knife bar 2 lower ends and handle 3 link together.When needs use this Wicresoft's cutter to carry out Minimally Invasive Surgery, the knife back 6 of this Wicresoft's cutter is against in the linked groups with knife bar 2 lateral surface, and relies on the strength of wrist to promote this Wicresoft's cutter, arrive illing tissue up to blade 1 to front slide, the operation that undergos surgery gets final product, and is very convenient.Because the knife back 6 peripheries are rounded, and knife bar 2 lateral surface and the knife back 6 are tangent, so will be difficult for scratching linked groups very along sliding when sliding with linked groups.In order further to strengthen the slyness of this Wicresoft's cutter, the cross section of the knife back 6 circumferential parts is arcuation.Handle 3 Cross-section Design are circular, like this when adjusting blade 1 direction with convenient.In order to prevent to skid, handle 3 outsides are provided with numb stricture of vagina 5.Blade 4 consistent with the bearing of trend of knife bar 2 towards also being arranged to, operation principle is similar, no longer carefully states at this.
