Description

technical field [0001] The invention relates to the technical field of ligation devices, in particular to a negative pressure automatic tightening ligation device. Background technique [0002] Acne is a common human disease, and ligation is one of the commonly used methods for treating acne. Its principle is to bind the base of the acne root, block the blood supply of the acne, make it shrink and fall off due to ischemia, and achieve the purpose of healing. [0003] The current clinical method of treating acne is usually completed by the operator with the help of simple instruments, which is not only time-consuming and laborious, but also easily causes bleeding and pain, and the removal process is inconvenient. Therefore, it is necessary to design a negative pressure automatic tightening ligation device with precise pressure control and convenient removal. Contents of the invention [0004] The object of the present invention is to provide a negative pressure automatic ...
