Description

Fire needle device capable of controlling depth of needle penetrating into skin

Technical Field

The invention relates to the technical field of traditional Chinese medical appliances, in particular to a fire needle appliance capable of controlling the depth of a needle penetrating into skin.

Background

All the treatment methods of human beings are mostly needed to be made from natural materials, or to create appliances, or to perform auxiliary treatment. Even psychotherapy requires an artificially created atmosphere and a device or decoration having a placebo effect. Macroscopically, there are two main categories of foreign objects for medical activities, on one hand, the foreign objects are used for internal administration of medicines for conditioning invisible internal world, and over thousands of years, from experience to empirical meaning, eastern and western doctors continuously explore the aspect and explain the invisible mechanism by different theoretical logics; on the other hand, it is an extracorporeal treatment device of earlier origin, used to perform various stimuli on the "in view" body to produce a therapeutic effect.

The external treatment method has been developed to date, and only oriental medicine has the highest degree of theorization of acupuncture and moxibustion, and the academic system is the most perfect, and it is especially noted that the related instruments are increasingly diverse and sophisticated, and have corresponding standardized production standards.

From the historical backtracking, the acupuncture and moxibustion apparatus gradually develops to the fine manufacturing before the recent generation, although the acupuncture and moxibustion apparatus has a diversity trend, no subversion innovation occurs, and the fine manufacturing means that the pain is relieved and the accident is reduced; in recent times, in modern development, acupuncture tools and moxibustion tools have a tendency to combine with modern technology, and various substitute media such as electricity, light, magnetism and the like appear, while metal acupuncture tools and moxibustion tools in the traditional sense are rarely renewed except for the trend of increasingly standardization.

The existing fire needle apparatus used in clinic has the following problems: because of different operation proficiency of the operators, especially for beginners, the proper skin depth of acupuncture points penetrated by fire needles is difficult to master, and the acupuncture penetration depth of different operation acupuncture points by the same operator cannot be fixed, so that the curative effect can be influenced, and safety incidents can also occur.

In addition, the existing needle burning mode is difficult to control the needle burning temperature, and meanwhile, operators are different and the same operator moves the fire needle from a fire source to acupuncture points at different speeds, so that the temperature cannot be fixed when the fire needle enters skin acupuncture points.
