Problems solved by technology

[0004] The traditional medical needle-knife structure is relatively simple, and the usage scenarios and functions are also relatively single. In the actual treatment process, it may be necessary to comprehensively use a variety of knife-type acupuncture instruments, which is inconvenient to use and switch
In the prior art, in order to ensure hygiene and safety, various types of acupuncture and moxibustion appliances are mostly in the form of independent closed packaging. Different packaging needs to be removed when taking different acupuncture and moxibustion appliances. It is difficult for the acupuncture practitioner to operate independently. The ongoing diagnosis and treatment process must be interrupted, which not only delays time but also makes the operation extremely inconvenient
