Problems solved by technology

[0002] Existing medical suction medical needles mostly use ordinary injection needles, and the needles are pointed. When performing cosmetic treatments such as liposuction on patients, because the needles need to be located in the body for a long time, the pointed needles are easy to get stuck in the body. Stabbing the patient in the body will cause inevitable secondary injury, and the sharp needle tip will also make the patient feel more pain in the body

Embodiment Construction

[0016] Combine now figure 1 , figure 2 To further illustrate the present invention, a painless suction medical needle includes a needle body 1, and the needle body 1 is made of 304 stainless steel. The needle body 1 is a hollow cylinder, and a pinhole 2 is opened on the side of the needle body 1, and the pinhole 2 is formed by laser cutting. The top of the needle body 1 is provided with a needle head 3 in contact with the human body, the needle head 3 is a smooth curved surface, and the needle head 3 and the needle body 1 are connected by welding. The needle body 1 is evenly provided with several scale marks 4 for marking the insertion depth of the needle body 1 into the human body. The scale marks 4 are etched on the surface of the needle body 1 by chemical corrosion. The present invention welds the front end of the suction medical needle with a smooth arc-shaped needle 3 through a welding process, so that the needle 3 will not stab the patient in the body and cause unavo...

Abstract

The invention discloses a painless suction type medical needle and a production technology thereof. A smooth and arc-shaped needle head is welded at the front end of the suction type medical needle with a welding technology, so that the needle head in the body cannot cause inevitable secondary injuries due to puncture of a patient, and the pain of the patient can be greatly relieved when the smooth and arc-shaped needle head is located in the body; the needle head is round and safer than a sharp-head needle, an opening is formed in the side surface, an injection medium is more uniform, the injection effect is better, and through cooperation of TIG (tungsten inert gas) welding with subsequent hydraulic and pneumatic purging grinding, the needle head welded on a tiny needle tube is firm and smooth. The TIG welding technology is adopted, a workpiece is molten, a specific molten pool is formed, the tiny needle head and needle tube can be well combined and cannot separate and fall easily, the needle tube cannot be damaged and deformed during welding, a black film formed by chemically corroded scale marks is firm, the processing temperature is low, and accordingly, the attractive appearance can be kept.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a painless suction medical needle and a production process thereof. Background technique [0002] Existing medical suction medical needles mostly use ordinary injection needles, and the needles are pointed. When performing cosmetic treatments such as liposuction on patients, because the needles need to be located in the body for a long time, the pointed needles are easy to get stuck in the body. Stabbing the patient inside the body will cause inevitable secondary injury, and the sharp needle tip will also make the patient feel more pain in the body. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a painless suction medical needle and its production process. [0004] The technical solution adopted by the present invention is: a painless suction medical needle, comprising a needle body, the needle b...
