ABSTRACT:
An obtained tissue extractor is used in combination with a biopsy forceps. The biopsy forceps includes an elongate insertion portion to be inserted into a body, and a biopsy cup provided at a tip of the insertion portion, including a pair of cup bodies which obtains a living body tissue, and having holes communicating with the inside of the cup bodies. The obtained tissue extractor includes protrusions, and the protrusions enter the inside of the cup bodies from the holes of the cup bodies when the cup bodies are driven to open in a state set at the distal end of the insertion portion, in order to release the obtained tissue from the cup bodies.
