Description

Needle knife with semicircular edge

Technical Field

The utility model relates to the technical field of medical equipment, more specifically say, it relates to semicircle sword needle sword.

Background

The needle knife medicine is a new medical subject created in traditional Chinese medicine and pharmacy by professor Zhuhan chapter based on anatomy and meridian science and by referring to the relevant principle of modern medical surgery. The size and length of the needle knife are similar to those of an acupuncture needle, but the tip of the needle knife is mostly a flat blade and a dovetail blade, so that cutting and loosening operations can be performed, the needle knife not only has the effect of traditional Chinese medicine acupuncture, but also has the characteristics of a scalpel, and from the perspective of traditional Chinese medicine, the needle knife can relax tendons and activate collaterals, so that wind-cold moisture is discharged, qi and blood meridians and collaterals are smooth to run, and the needle knife acts on acupuncture points to achieve the effects of regulating yin and yang, dredging meridians, regulating viscera, strengthening body resistance and eliminating evil in traditional Chinese medicine acupuncture. From the physiological and pathological aspects, the needle knife can stimulate nerves, generate bioelectric effect, regulate neural network, generate fast coordinated chemical or mechanical response, release and strip pain points caused by ligament adhesion, contracture and muscle tension, reduce pressure of compressed tissues and nerves, and relieve pain, numbness, joint stiffness and the like of the tissues. Domestic research shows that in the range of treatment indications of small needle knives, the cure rate is 1.26 times that of surgical operations and 4.15 times that of medicines and other therapies.

Although the effect of the needle knife therapy is quite good, the needle insertion depth of the needle knife is not easy to control during actual treatment, and particularly for novice doctors, even doctors with abundant experience, the situation that the needle insertion is too deep or the force is not appropriate can occur, so that unnecessary injury is caused to patients; and the most pointed end of current needle sword is flat mouthful of cutting edge or dovetail cutting edge, and the dovetail cutting edge is only applicable to single disease, and the incision face that the flat mouthful of cutting edge caused is great, and wound recovery time is long, also has certain resistance when doctor advances the needle, influences the operation, still can increase patient's painful sense.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a semicircle sword needle sword has solved the great problem of current needle sword incision face.

The above technical purpose of the present invention can be achieved by the following technical solutions: semicircular blade needle sword, including handle portion and needle sword portion, needle sword portion fixed connection is on handle portion, needle sword portion comprises needle body, connecting portion and cutting edge, the blade of cutting edge is semi-circular structure, the cutting edge of a knife edge angle of opening of cutting edge is 15-20, the one end that the cutting edge was kept away from to the cutting edge is connected with connecting portion integrated into one piece, the cross section of connecting portion is oval, the major axis of connecting portion equals with the diameter of needle body, the minor axis of connecting portion is by supreme crescent down, the minor axis of connecting portion equals with the diameter of needle body when reaching the biggest, the one end that the cutting edge was kept away from to connecting portion is connected with needle body integrated into one piece.
