Description

A kind of micro-needle knife

Technical field

This utility model relates to technical field of medical instruments, specifically a kind of micro-needle knife.

Background technology

Pin cutter is one common medical apparatus, is ideal closed operation and acupuncture instrument to conciliation, treatment chronic soft tissue disease and hyperosteogeny pathological changes.

At present, the small needle knife generally used is made up of needle handle, solid needle body and knife-edge pin cutting edge of a knife or a sword three part substantially, the pin cutter of prior art carries out in therapeutic process to adhesion, contracture, the soft tissue of plumpness and the bone structure of hypertrophy regression, because pin cutter is comparatively thick, large to skin trauma, even can hurt the tissues such as blood vessel, obvious pain is had during inserting needle, thus preoperatively need local anesthesia, but anaesthetic has toxic and side effects again, patient is not easy to accept.

Also occur hollow pin cutter in prior art, but its there is no cutting-up, cut shovel, loosen, the function such as stripping, it peels off the very difficult operation of function in other words, brings larger misery to patient.

Utility model content

The deficiency that this utility model exists to overcome prior art, provides a kind of micro-needle knife.

This utility model can be achieved by taking following technical scheme:

A kind of micro-needle knife, comprise the needle body and the handle of tubulose, the end of the described needle body is connected with described handle, the front cutting of the described needle body goes out the edge of a knife tilted with needle body axis, described edge of a knife front end is flat mouth blade, the both sides of described flat mouth blade are curved blade, and curved blade described in described flat mouth blade and two forms the blade group closed.

Further, described handle is flat, the side flat horizontal surface of described handle towards with described edge of a knife oblique section towards consistent.

Further again, the flat horizontal surface of described handle offers anti-slip tank.

Further again, described handle is provided with the inward recess that applicable medical syringe connects, described inward recess is communicated with the described needle body.

Preferably, described handle is transparent or semitransparent.

Preferably, the described needle body is by austenite stainless steel making.

Further, can also be provided with over cap, it is outer and be connected with handle that over cap is enclosed within the needle body.

Preferably, described over cap adopts polypropylene material to make.

Compared with prior art, the beneficial effects of the utility model are: the needle body is hollow pipe-type, can discharge medicinal liquid to operative site local, and can make greatly to reduce the wound of skin, during operation, substantially painless or hypodynia, avoids the use of anaesthetic, and patient Geng Yi accepts; The micro-needle knife edge of a knife there is the Rhizoma Cimicifugae Acerinae sword such as the flat mouth blade of front end and the Roound edge of both sides, it is made more to be conducive in stripping of loosening, to sweep the realization that loose and cutting-up cuts shovel function, function than conventional needle cutter and needle knife for injection more powerful, the cutting power of the prior art that can match in excellence or beauty empty micropin cutter; Do not have conventional needle cutter strict to operationlocation's environmental requirement, conventional needle cutter because of its wound large, just can need operate after operative site sterile drape, anaesthetic injection in gnotobasis, require high to the sterility of environment, and the operation of this method because of its wound little, be similar to common intramuscular injection, just can carry out after partly sterilised, therefore require relatively low to the sterility of environment.

Detailed description of the invention

Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described in detail.

As shown in Figure 1 and Figure 2, a kind of micro-needle knife, comprise the needle body 1 and the handle 2 of tubulose, the end of the needle body 1 is connected with handle 2, the front cutting of the needle body 1 goes out the edge of a knife tilted with the needle body 1 axis, edge of a knife front end is flat mouth blade 3, and the both sides of flat mouth blade 3 are curved blade 4, and flat mouth blade 3 and two curved blades 4 form the blade group closed.The blade of combination makes this micro-needle knife front end and both sides all can cut, and makes it have to scrape to cut, sweep loose and the function such as to cut off.

Handle 2 in flat, the side flat horizontal surface of handle 2 towards with edge of a knife oblique section towards consistent.Can make need not to divert attention in surgical process confirm the edge of a knife towards, can be confirmed by hand-held handle 2, the direction of the edge of a knife during operation, can be known clearly at any time, facilitate the operation technique of doctor.Overcoming prior art needs special labelling to the defect determining that in edge of a knife direction, art, doctor needs the position of moment observation labelling, can disperse the attention of doctor to a certain extent, surgical effect be produced to risk.

The flat horizontal surface of handle 2 offers anti-slip tank 5, prevent operator from operating and grip the phenomenon occurring skidding.

Handle 2 is provided with the inward recess 6 that applicable medical syringe connects, inward recess 6 is communicated with the needle body 1, carrying out local application over the course for the treatment of, greatly simplifying in operation process and operating the dispenser of operative site as needed local to use medicine can connect syringe.

Handle 2 described in the present embodiment is transparent.Can understanding with or without injured blood vessel with or without blood back by observing needle handle place in operating process, avoiding causing vascular tear.Also translucent material can be adopted.

In order to meet the enough toughness of micro-needle knife needs and requirement of strength further, the needle body is by austenite stainless steel making.

In order to make micro-needle knife easy to carry, the needle body 1 is accommodated in over cap 7, and it is outer and be connected with handle that over cap 7 is enclosed within the needle body 1.Over cap can adopt the polypropylene material of environmental protection, nontoxic odorless, even if contact medicine also can not produce chemical reaction, safe and sanitary, is convenient for carrying use.

Only as described above, be only the preferred embodiment of this utility model, when can not limit the scope of this utility model enforcement with this, namely generally according to equivalence change simple done by the content described in this utility model claim and utility model description and modification, all still belong within this utility model claim scope.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction this utility model.
