I'm about to do a colonoscopy and want to know the difference between a disposable biopsy forceps and a regular biopsy forceps

Biopsy forceps are mainly used to extract tissue from the lesion site under the microscope in the process of endoscopy. After the tissue is bitten off, the wound will be damaged and bleed. So biopsy forceps are usually sterilized or sterilized. This seems to be the 80's infusion, injection are used with glass syringes, and glass buckets, repeated use of needles, these things a patient used up, after disinfection for other patients, if disinfection is not thorough is very easy to lead to cross infection, especially AIDS, hepatitis and so on.
