Embodiment 1

[0027] A thermal needle whose heat is concentrated at the tip of the needle. The thermal needle is a stainless steel tube thermal needle. A copper ball is welded inside the sharp end of the thermal needle. The copper ball is connected to the copper wire, and the copper wire passes inside the stainless steel tube and does not touch the inner wall. Contact, the outer wall of the hot needle 3-10mm away from the sharp end of the hot needle is plated with 1-2μm silver plating, the tail of the stainless steel tube hot needle and the copper wire are respectively connected to the two poles of the power supply, when the current passes, the part that is not plated with silver near the needle tip The resistance is large, and the heat generated is large, so that the input energy is converted into heat and concentrated near the needle tip.

Embodiment 2

[0029] (1) Use energy storage spot welding equipment to melt a small ball with a diameter larger than the stainless steel tube hot needle at the tip of the peeled copper wire. The outer diameter of the stainless steel tube hot needle is 0.4mm, the inner diameter is 0.2mm, and the copper wire The diameter is 0.09mm constantan wire.

[0030] (2) Insert the hot needle of the stainless steel tube into the crucible with liquid BAg72Cu brazing filler metal (melting point 779°C), turn on the high-frequency heater to heat it to 850-900°C in the protective atmosphere of argon, and pass the " "Push and pull" to wet the copper wire and the inner wall of the tube, and keep it for 3-5 seconds to realize the connection between the hot needle of the stainless steel tube and the copper wire. The copper wire passes through the inside of the stainless steel tube and does not contact the inner wall. The flux is FB101.

[0031] (3) Process the welded end to form a conical sharp angle, and the sur...

[0034] (1) Use energy storage spot welding equipment to melt a small ball with a diameter larger than the stainless steel tube hot needle at the tip of the peeled copper wire. The outer diameter of the stainless steel tube hot needle is 0.4mm, the inner diameter is 0.2mm, and the copper wire The diameter is 0.09mm constantan wire.

[0035] (2) Insert the hot needle of the stainless steel tube into the crucible with liquid BAg72Cu brazing filler metal (melting point 779°C), turn on the high-frequency heater to heat it to 850-900°C in the protective atmosphere of argon, and pass the " "Push and pull" to wet the copper wire and the inner wall of the tube, and keep for 3-5 seconds to realize the connection between the hot needle of the stainless steel tube and the copper wire. The copper wire passes through the inside of the stainless steel tube and does not contact the inner wall. The flux is FB102.

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...
