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
