Description

Improved spring type electric fire needle

Technical Field

The utility model relates to the technical field of traditional Chinese medicine physiotherapy and discloses an improved spring type electric fire needle.

Background

Fire acupuncture therapy has a long history, has the efficacies of warming yang, dispelling cold, softening hard masses, dissipating stagnation and removing blood stasis, and is mainly used for treating diseases such as rheumatic arthralgia, pyocutaneous disease, carbuncle, scrofula, subcutaneous nodule, jaundice, mania, slight withering, abdominal pain and the like. When in treatment, a patient holds the alcohol burner with the left hand, the position is as close as possible to the operation position, holds the needle handle with the thumb, the index finger and the middle finger of the right hand, puts the needle body on the flame, burns until red and white, and then quickly pricks and withdraws the needle. The technical difficulty of fire needle therapy lies in that the operation is stable, accurate and fast, the preset requirements on the technical indexes of the acupuncture position, depth, speed and the like are achieved by applying the wrist force, and the needle body is accurately inserted into the operation position to reach the depth of pathological changes and rapidly goes in and out, and the time is not more than 0.5 second/time.
