| description | A tissue cutter, comprising a tissue cutting stent (1, 1', 1") and a first tightening wire (5). The tissue cutting stent (1, 1', 1") is expandable in the radial direction. The expanded tissue cutting stent (1, 1', 1") is horn-shaped, gradually expands from a proximal end to a distal end, and forms a horn-shaped content space. A plurality of first threading holes (50, 50') are provided on the distal end of the tissue cutting stent (1, 1', 1"). The plurality of first threading holes (50, 50') are arranged along the circumferential direction of the tissue cutting stent (1, 1', 1"). The first tightening wire (5) passes through the plurality of first threading holes (50, 50'), and is provided with a first end and a second end opposite to each other. The first end is fixed to starting threading holes (52) in the plurality of first threading holes (50, 50'). The tissue cutter is employed to cut a small wound required for lesion tissue, and the resection area is accurate. Therefore, more normal tissue organs can be r |
