Abstract

A kind of needle blade scalpel, including cutter hub, the rear end of cutter hub are handle, and front end is cutter head, and the front end of cutter head is point of a knife, and the side of point of a knife extends rearward to be knife spine, and the other side extends rearward to be blade, and blade is the curved surface of evagination.Blade area is equipped with billhook, and billhook is stretched out from cutter head to side rear, and the two sides of billhook 30 are all blade.Compared with the existing technology, the technical effect of the utility model is that segment design is point of a knife by the utility model, facilitates piercing patient's body, mitigates patient suffering.In addition, side is blade, cutting action can be completed in patient's body, furthermore the diameter of cutter hub, with cutter head equivalent width, cutter head very little, it is excessive to avoid notch, do not have to suture, extracting is only pin hole.Doctor's use is facilitated, minimally invasive purpose has been reached.

Description

A kind of needle blade scalpel

Technical field

The utility model relates to a kind of scalpels.

Background technique

The level blade needle knife and some acupuncture needles for having Pear-Shaped knife handle and traditional operation knife knife handle clinically used at present It is transformed needle knife (such as Kirschner wire knife).Referring to Fig. 5, cutter head is flat cutter head 50, be exactly end face is blade 51, the side of 51 two sides of blade 52 be not blade.

Utility model content

The technical problems to be solved in the utility model: in clinic, it is sometimes necessary to cut flesh internal (being exactly in human body) Tendon extends, and de Quervain's disease loosens, and the cutting of muscle or fascia, which is loosened, to be subtracted etc., and this knife is unable to satisfy demand.

The technical solution of the utility model specifically:

A kind of needle blade scalpel, including cutter hub, the rear end of cutter hub are handle, and front end is cutter head, and the front end of cutter head is knife Point, the side of point of a knife extend rearward to be knife spine, and the other side extends rearward to be blade, and blade is the curved surface of evagination.

Blade area is equipped with billhook, and billhook is stretched out from cutter head to side rear, and the two sides of billhook 30 are all blade.

The profile of billhook entirety is all located within blade area.

The profile of billhook entirety is all located at other than blade area, and billhook is the lug of an evagination.

Plane where blade is parallel with the plane where handle.

Compared with the existing technology, the technical effect of the utility model is that segment design is point of a knife by the utility model, convenient It is pierced into patient's body, mitigates patient suffering.In addition, side is blade, cutting action, furthermore cutter hub can be completed in patient's body Diameter with cutter head equivalent width, cutter head very little, it is excessive to avoid notch, does not have to suture, extracting is only pin hole.Facilitate doctor It uses, has reached minimally invasive purpose.

Specific embodiment

Picture 1-4, the rear end of a kind of needle blade scalpel, including cutter hub 10, cutter hub 10 is handle 11, and front end is cutter head 12。

Referring to fig. 2, the front end of cutter head 12 is point of a knife 20, and the side of point of a knife 20 extends rearward to be knife spine 21, and the other side is backward Blade 22 is extended to, blade 22 is the curved surface of evagination.Blade 22 can complete cutting action in patient's body.

In clinic, such as apoplexy sequela, the lengthening of tendon application of brain paralysis, paraplegia.Cut tendon or when stndon sheath with And muscle, the fascia of spasm need to be cut after cutting when subtracting, knife edge part is located at the downside of tendon or muscle, fascia, this When need the tendon that cuts or muscle, fascia not to cut completely through, it is all right to mention knife until blade upwards if it is above scheme Part is located at the upside of tendon or muscle, fascia, need to be cut once again, aggravate patient suffering (having cut a knife) in this way, such as more Fig. 3-4,22nd area of blade are equipped with billhook 30, and billhook 30 is stretched out from cutter head 12 to side rear, and the two sides of billhook 30 are all blade.This Sample, when mentioning knife upwards, billhook 30, which has, completes above-mentioned cutting, avoids and cuts again, alleviates patient suffering.

At this point, being divided into two kinds of situations, such as Fig. 3, the whole profile of billhook 30 is all located within 22nd area of blade, at this point, billhook 30 be made of due to opening up gap at blade 22.

Or such as Fig. 4, the whole profile of billhook 30 are all located at other than 22nd area of blade, billhook 30 is the lug of an evagination.

In order to easy to operate, the plane where blade 22 is parallel with the plane where handle 11.

Its working principle is that:

It needs in use, needing the piercing patient's body of point of a knife 20 just straight using blade 22 internal (being exactly in human body) Connect completion cutting.

If this occurs: after cutting, knife edge part is located at the downside of tendon or muscle, fascia, needs at this time The tendon or muscle to be cut are not cut completely through.Using billhook 30, when mentioning knife upwards, (being exactly knife) completes cutting.This Sample entirety cutter head enters patient's body one-in-and-one-out and just completes entire movement, and other content participates in the prior art.

Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as The protection scope of the utility model.
