Description

Blade injection thread burial needle knife

Technical Field

The invention relates to the technical field of medical machinery, in particular to a needle knife for embedding a thread by edge injection.

Background

The small needle knife is an acupuncture tool which is made of metal materials and is similar to a needle and a knife in shape, is developed and formed by combining a modern medical surgical knife on the basis of a needle, a sharp needle and the like in an ancient nine-needle, is a product organically combined with a soft tissue release operation, has a history of more than ten years and a trend of further development in recent years, and is regarded by people in the world. The small needle knife therapy is a closed loosening operation between a surgical method and a non-surgical method, and is formed by combining a needle punching method on the basis of an open surgical method. The operation of the small needle knife therapy is characterized in that the treatment part is punctured into the deep part to the pathological change part to be easily cut and stripped to stimulate different operation processes so as to achieve the purposes of relieving pain and removing diseases.

The acupoint medicated thread therapy is a product combining acupuncture theory, traditional Chinese medicine science and modern physics, and achieves the purpose of treating diseases by transmitting stimulation information, energy and traditional Chinese medicines into the body through meridians and collaterals through the biophysical action and biochemical change generated in acupoints by needles and medicated threads. In fact, the catgut embedding therapy is a combined treatment method combining multiple therapies and multiple effects.

In clinical treatment, some patients need to be treated by a method of combining a needle knife and a thread embedding, the needle knife is firstly used for cutting and stripping, and then the thread embedding needle is used for embedding foreign body protein medicine threads on an affected part to stimulate local acupuncture points, so that the immunity of the human body is stimulated. The existing treatment method needs to respectively operate the needle knife and the thread burial needle twice, has complex operation, can not ensure the consistent cutting and thread burial positions, has higher treatment expenditure for patients, and also needs to bear more pain.

Therefore, it is necessary to develop a needle knife for thread burial which is combined with the needle knife for thread burial.

The utility model patent of the chinese patent database with application number CN201720209295.2, "a disposable needle-knife thread burying needle" discloses the following technical scheme: a disposable needle-knife thread burial needle comprises a puncture needle tube, a needle seat, a lining core seat and a protective sleeve, wherein the top end of the puncture needle tube is fixedly connected with the needle seat, the lining core is inserted into the puncture needle tube, the top end of the lining core is fixedly connected with the lining core seat, and the protective sleeve is sleeved on the puncture needle tube; the needle point of the puncture needle tube is provided with an arc-shaped cutting edge part.

The scheme cuts and peels off through the needle point cutting edge of the puncture needle tube, and the protein thread is punched into an affected part from the small hole in the puncture needle tube through the lining core. However, in practical application, the cylindrical portion at the top of the needle seat is provided with an opening corresponding to the bottom of the bushing core seat, and the opening is larger than the through hole of the puncture needle tube, so that the albumen wire is usually blocked by the bottom of the opening when the albumen wire is inserted into the through hole from the opening of the cylindrical portion, the albumen wire is difficult to be pressed into the through hole rapidly, medical staff is required to try to draw the albumen wire into the through hole for many times, and the use is inconvenient; in addition, the egg white line is the tiny line of complete aseptic, and above-mentioned scheme still needs medical personnel to move the egg white line from the storage bag to the opening of cylinder portion with the hand, especially still need move the egg white line many times in the opening and just can scratch it in the through-hole, can't guarantee the thorough aseptic of egg white line, has the potential safety hazard.

Disclosure of Invention

The invention aims to provide a needle knife for thread burial by cutting edge injection, which can realize the needle knife cutting and thread burial operation at the same time, has simple and quick process of threading a protein thread, does not need medical personnel to transfer the protein thread between a storage bag and a needle seat by hands, ensures the sterility of the protein thread, avoids potential safety hazard and improves the threading efficiency at the same time.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the utility model provides a blade injection needle sword of sunkening cord, includes needle tubing, needle file, sunkening cord needle and sunkening cord needle file, the inside first through-hole that runs through that is equipped with of needle tubing, the top with the needle file bottom is fixed, and the bottom is equipped with the cutting blade, the needle file inside be equipped with the toper chamber of taper angle down of first through-hole intercommunication, sunkening cord needle file bottom with toper chamber upper segment matches, sunkening cord needle top with sunkening cord needle file bottom surface is fixed, sunkening cord needle external diameter with first through-hole matches, the inside second through-hole that runs through that is equipped with of sunkening cord needle, second through-hole bottom is equipped with and keeps off the net, sunkening cord needle file inside be equipped with the third through-hole of second through-hole intercommunication.

Compared with the prior art, the invention has the beneficial effects that:

1. according to the invention, the conical cavity with the downward taper angle communicated with the first through hole is arranged in the needle base, the protein thread directly enters the first through hole from the conical cavity, the situation that the protein thread is blocked by the bottom of the needle base is avoided, the protein thread can be rapidly inserted into the first through hole, and the threading efficiency is improved;

2. according to the invention, the second through hole is further arranged in the thread burial needle seat, the third through hole connected with the second through hole is arranged in the thread burial needle seat, and the end part of the third through hole is connected with the negative pressure device;

3. according to the invention, the bottom end of the second through hole in the thread burial needle is provided with the baffle net, so that the situation that a protein thread enters the inside of the second through hole when the thread burial needle injects the protein thread can be avoided, and the normal injection of the protein thread is ensured.

The invention further improves the scheme as follows:

furthermore, the negative pressure device comprises a negative pressure ball which is fixed on the top surface of the thread embedding needle seat and connected with the third through hole.
