[0002] The appearance of the small needle knife is similar to that of an acupuncture needle, and its tip has a narrow blade, which can play the dual functions of acupuncture and knife cutting. It is a new type of medical surgical treatment instrument. Most of the existing small needle knives are in the form of acupuncture needles. The whole is a needle, and a handle is provided on the upper end for the user to hold. The user can pierce the needle through the handle or cut through the knife head. However, in some current use environments, it is usually necessary to pierce the patient's affected area and inject liquid medicine, or embed a medical absorbable thread, so as to achieve the four-fold treatment effect of knife, needle, medicine and thread. It is difficult for the existing small needle knife to achieve this function, resulting in poor overall functionality and use effect of the existing small needle knife when it is used. At the same time, when the existing small needle knife is used, the knife must be disinfected and replaced as a whole after use. After multiple uses, the knife head becomes blunt and needs to be replaced as a whole. It is difficult to reuse it, and the cost of use is high.
