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.

Intrauterine tissue collection instrument

A living cell transplanting device has a flexible tube capable of accommodating living cells and a cell pushing shaft inserted into the tube. The tube has a lumen penetrating therethrough and a reduced diameter front end open portion. The shaft has a small diameter end portion having a diameter smaller than that of the reduced diameter front end open portion and an enlarged diameter portion having an outer diameter larger than an inner diameter of reduced diameter front end open portion. Owing to contact between the enlarged diameter portion of the shaft and the reduced diameter front end open portion of the tube, a progress of the shaft is regulated. By pushing the shaft into the tube after the contact between the enlarged diameter portion and the reduced diameter front end open portion finishes, the enlarged diameter portion of the shaft passes through said reduced diameter front end open portion with expanding the reduced diameter front end open portion of the tube and projects beyond the reduced diameter front end open portion of the tube.
