Description

Technical field: [0001] The invention relates to medical equipment, in particular to a biopsy expander. Background technique: [0002] Biopsy is the abbreviation of biopsy, which is to use surgical methods or puncture / endoscopic instruments to obtain human tissue for pathological examination before and after treatment. Biopsy can confirm the histological diagnosis, guide the clinical treatment plan; and follow-up to confirm the treatment effect.

Problems solved by technology

At present, for the biopsy of the digestive tract, when patients are used to extract exfoliated cells from the esophagus, the patient is usually asked to swallow a balloon with a brush, and then inflate it to inflate the balloon to extract exfoliated cells from the mucosa. This operation is very troublesome and sometimes requires Swallowing the balloon repeatedly is time-consuming and laborious, and the number of samples obtained is limited, sometimes unable to meet the needs of biopsy
