摘要： A surgical resecting tool (1) whereby a cartilage, cartilage knob or tumor within a body cavity, for example, such articulation cavity as of a knee is resected from outside the body cavity without being incised and is taken out of the body cavity is provided with a rigid outer tube (4) removably provided in the front part of a body part (2) which is also a holding part and has a rotary power source 28. The outer tube (4) is provided with an opening (7) near the front end part and with a curved part 9 in the rear of the opening (7). The outer tube 4 is provided with a cutting part (13) in the front end part and is removably connected in the rear end part to the rotary power source (28) to resect a living body tissue by rotating and driving the cutting part (13). An inner tube (6) having a flexible part (12) at least in the position corresponding to the above mentioned curved part (9 ) is inserted through the outer tube (4).

摘要： A surgical resecting instrument whereby a cartilage, joint bump or tumor within a body cavity such as a joint cavity, for example, of a knee is resected from outside the body cavity without incising it and is discharged out of the body cavity has a body part providing a rotary driving connection and an insertable part to be inserted into a tissue within a living body attached to and extending from a front end part of the body part. The insertable part comprises a tubular outer tube opened in the tip part and forming an outer shell of the insertable part and an inner tube provided within the outer tube and rotated and driven by the rotary driving connection. An outer tubular blade is provided in the tip part of the outer tube. The tip of the outer blade is open and has a slot extending from the tip in a peripheral wall and forming a blade part at an edge of the slot. An inner blade for shearing a living body tissue together with the outer blade part is provided in the tip part of the inner tube within the outer blade. The inner blade has a shearing blade part formed so that the angle formed with the outer blade part at the beginning of a shearing action will be larger than the angle formed with the blade part as the shearing action continues.
