Description

Needle needle and its application

Technical field

The present disclosure relates to a special accessory tool for needle handling of a human or animal, and more particularly to a needle feeder and its use.

Background technique

Acupuncture is currently the more popular homeopathic approach, which includes traditional acupuncture and modern floating needle therapy. Among them, floating needle therapy is acupuncture treatment with acupuncture and other acupuncture activities such as disposable floating needles and needles in the peripheral skin of the localized pain or the superficial superficial fascia of the painful distal end. It is easy to operate, economical, safe and has no side effects. It has a wide range of effects on clinical subjects, especially for the treatment of pain and other diseases.

In order to overcome the inaccuracy of the angle of the manual needle insertion, the difficulty of controlling the depth of the needle, and the pain caused by the operator's error, the applicant invented a special needle feeder for floating needles to improve the above-mentioned deficiencies. The applicant of the present application applied for a floating needle needle feeder on August 23, 2011, the application number is 201120308612.9, the needle needle can be used with the floating needle needle to control the angle and depth of the hypodermic needle to achieve Needle accuracy reduces needlestick errors and pain. The needle needle is composed of a needle pusher lower shell, an upper needle upper shell, a fixing groove and a connecting rod to form a pusher seat, an elastic device, a button device, a front end of the needle insert base, and the like, and the needle is controlled by a connecting rod.

In the long-term practice, it has been found that the above-mentioned floating needle needle inserter solves the problems of the accuracy of the needle feeding needle, but also has problems such as poor stability of the needle and difficulty in disinfecting the joint, resulting in low patient compliance. The risk of infection increases, and practitioners are required to frequently change the needle device, resulting in shortened service life, replacement cost, and maintenance cost of the needle device. In order to solve the above problems, the applicant of the present application invented a novel detachable needle feeder which can be disassembled before and after use, and which is detachable while maintaining a stable needle insertion effect, and is applicable to various types. The needle can be used for the treatment of floating needle handling and other acupunctures in the human or animal body.
