Description

technical field [0001] The invention relates to a button-type locking device for medical forceps and an unlocking method thereof, which are mainly used for locking switching control of surgical instruments and belong to the technical field of medical instruments. Background technique [0002] Hand-held instruments for laparoscopic surgery, especially grasping forceps, such as fine-toothed grasping forceps, gallbladder grasping forceps, etc., in clinical application environments, in order to reduce operator fatigue, a set of ratchet mechanisms are usually designed to achieve self-locking. That is, after the operator uses the grasping forceps to grasp the tissue, the ratchet mechanism locks itself immediately, so that the operator does not need to hold the forceps for a long time to maintain the grasping state. [0003] However, in a real clinical application environment, for part of the use time or part of the surgical operation, the operator has to repeatedly grasp and relea...
