So far, it is considered that anesthesia is needed to make a small needle knife. At present, acupuncturists are divided into two factions. Some old acupuncturists may be unwilling to do anesthesia, and some who are relatively middle-aged and work in regular hospitals are still willing to do anesthesia. Perhaps in private and private clinics, it may be considered that anesthesia has certain risks and is easy to cause anesthesia accidents. However, in order to improve the clinical effect and relieve the pain of patients, it is advocated to carry out needle knife treatment in a third-class hospital or a regular medical institution, and to carry out some humanized treatment and people-oriented treatment. And anesthesia will not happen unexpectedly. Anesthesia is safe, that is, local anesthesia, so anesthesia is still necessary. Otherwise, the needle knife is still very painful to make. It is different from acupuncture in principle and theoretical basis. Therefore, if anesthesia is carried out, firstly, patients can be treated painlessly and actively cooperate. Secondly, after anesthesia, 1.0mm or 0.8mm needle knife can be used, and 0.8mm and 1.0mm are the diameters of pointer knife, which can ensure the therapeutic effect. In order to relieve patients' pain, some clinics do not use anesthetics, but the needles become thinner, and may use 0.4mm or 0.6mm needle knives. When such a needle knife cuts and releases adhesion, its function will be relatively weakened. In other words, although the needle becomes thinner, it will not cause great pain during the treatment, but it may also affect the later curative effect. Therefore, 0.8mm and 1.0mm needle knives are commonly used in clinic. When treating a patient, after anesthesia, the patient will basically feel no pain. Therefore, the treatment should be safe, patients should be in a comfortable environment, and they should be treated happily, which is also very helpful to the clinical curative effect, so local anesthesia should be carried out to make a needle knife.
