Background

Biopsy is a short term for biopsy, while biopsy forceps are indispensable tools for taking pathological specimens in endoscopy, and are necessary for doctors to carry out pathological diagnosis on digestive diseases. The forceps head of the existing biopsy forceps often meets the situation that foreign matters are difficult to take off in the process of taking the object, and the position of the forceps head needs to be adjusted by repeatedly pushing and pulling, so that the human body can be greatly injured. In clinical practice, if a contaminated biopsy forceps is used to obtain a specimen, nosocomial infection will occur. More and more disposable bioptomes are therefore put into use, but assembly becomes a major problem. The conventional method is that a coating and a spring are pressed in a plane, the spring is pressed into an S-bend, so that an inner hole is deformed, a boosting pipe rubs against the inner hole of the spring pipe, the resistance is large, and the tensile resistance is unstable.
