[0002] Biopsy forceps are an indispensable tool for obtaining pathological specimens during endoscopic examination. During digestive endoscopic surgery, biopsy forceps are needed to bite and cut the gastrointestinal lesions for sampling and analysis, which is beneficial to the diagnosis of the disease and the normal progress of the operation.

[0003] Biopsy forceps in the prior art generally have multiple specifications and are used to sample polyps of different sizes. When the biopsy forceps do not match the size of the polyps, the biopsy forceps are likely to clamp the mucosa and damage it, or the polyps cannot be completely removed, which not only increases the difficulty of operation for medical staff, but also easily causes harm to patients, reducing the practicality of the biopsy forceps. To this end, we provide a multi-specification integrated biopsy forceps to solve the above problems. Utility Model Content
