The endoscope apparatus hand handle is required to have a size adjustment locking function or a function of preventing falling and locking after clamping tissues and foreign matters. For example: in the process of using the biopsy forceps to clamp tissues, an operator needs to control the clamping of the handles to the tissues through hand force, and the poor hand force control of the operator often causes difficult tissue clamping or the clamped tissues to fall off, so that the whole operation time is prolonged, and the operation efficiency is reduced; secondly, in the process of withdrawing the biopsy forceps after tissue clamping is finished, due to the fact that the length of an insertion portion of the biopsy forceps is long, the biopsy forceps often drop off due to poor control of hand strength of an operator when withdrawing, sampling times are required to be increased, operation time is prolonged, and damage to a patient is increased.

Some medical instruments need to adjust and limit the length of the working part and keep the working state in use, and the structure can realize limit locking of the handle at different positions of the medical instruments to adjust and ensure the length and the working state of the working part for convenience in operation.

Furthermore, typically during actual surgery, the physician manipulates the endoscope and the nurse operates such medical instruments with handles as an assistant. Most of the endoscopic instrument handles on the market at present have simple front-back push-pull functions, and nurses or assistants are required to push the instrument handles to open or push out working parts in the operation process. Some surgical procedures require that the working portion of the instrument be kept open or pushed out for a period of time, and the hands of the nurse or assistant must be kept pushing or pulling the handle, which can cause some fatigue to the hands.
