Abstract
An intrauterine tissue collecting instrument includes a flexible outer tube, a flexible inner tube within the outer tube, and a shaft member within the inner tube. The flexible outer tube includes an outer tube distal end portion that can be open at at least three slits 4. The flexible inner tube includes an inner tube distal end portion including a plurality of side openings. The shaft member includes a diameter-expanded distal end portion. The intrauterine tissue collecting instrument can collect intrauterine tissue through suction in a state where the inner tube protrudes from the outer tube within the uterus. The inner tube distal end portion can be housed again in the flexible outer tube within the uterus.
