Hot needle with heat concentrated at needle point part, and manufacturing method of hot needle

Abstract

The invention provides a hot needle with heat concentrated at a needle point part, and a manufacturing method of the hot needle. The hot needle has the key points that after braze welding to a stainless steel tube and a constantan wire, electrosilvering is performed on a stainless steel outer surface and in a position far away from the needle point part, so as to form a silver layer; a stainless steel and constantan wire, which are arranged at the tail end of the hot needle, are respectively connected with the two poles of a power source; due to the high conductivity of copper and silver, low pressure drop can be produced when current passes through; the resistance of a part which is near to the needle point and is not silvered is high, so that high pressure drop can be produced when the current passes through and a large amount of hot can be produced, so as to enable input energy to be collected to a part near the needle point. Therefore, the problem of incapability of reaching a curing temperature due to the same temperature of an entire traditional needle can be solved. Under the same heat input conditions, the temperature of a part, inserted into a human body for acupuncture, of the needle is increased, and the curing effect is improved. The hot needle produced by the method has a simple structure, is convenient to use and has a good curing effect.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a hot needle with heat concentrated on the needle tip and a manufacturing method thereof. Background technique [0002] Today, head, neck, back, shoulder, arm, lumbar, sacral, buttock, and leg pain are one of the most common and frequently occurring diseases in countries all over the world. In my country, there are many treatment methods for soft tissue pain, among which acupuncture is an important one. Acupuncture and moxibustion is the medical technique of "treating internal diseases externally", which is the collective name of acupuncture and moxibustion. [0003] Hot needling is a new acupuncture method based on the combination of the advantages of warm needling and fire needling. Hot needle instrument is a new type of acupuncture and moxibustion treatment instrument developed according to the theory of traditional Chinese medicine acupuncture. , fire acupuncture and othe...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to solve the problem that the temperature of the whole needle of the hot needle produced by the existing technology is basically the same, so that the required treatment temperature cannot be reached. After welding, the outer wall of the stainless steel tube is plated with silver at a certain distance from the needle tip to improve the conductivity of this part, so that the input heat is concentrated on the needle tip that penetrates into the human body to achieve a better therapeutic effect
