[0005] The positioning ring has an outwardly protruding accommodating portion, and the visible catheter is embedded in the accommodating portion.

[0006] The cutter and the vacuum tube are fixed by thread rotation.

[0007] The cutter is a stepped tube, the upper part of the cutter has a large diameter section, the vacuum tube is also a stepped tube, the upper part of the vacuum tube also has a large diameter section, the inner hole wall of the large diameter section of the cutter is provided with a thread, the outer wall of the large diameter section of the vacuum tube is provided with a thread, and the large diameter section of the vacuum tube is rotatably arranged in the large diameter section of the cutter.

[0008] The positioning ring is limitedly matched with the stepped surface of the upper part of the cutter.

[0009] The blade of this utility model has a detachable handle on the upper part, and a visual tube is fixed on the positioning ring of the handle. The internal tissue condition of the 'dowager's hump' can be observed through the visual tube, which makes it convenient for medical staff to remove the hyperplastic tissue inside the 'dowager's hump. In addition, the blade is equipped with a handle for medical staff to hold.

[0010] In addition, the handle of this utility model is detachably mounted on the blade. The handle can be removed in the early stage of the operation to facilitate the excision. When the hyperplastic tissue has been almost completely removed, the handle and visual catheter are then installed to remove any remaining tissue. Attached Figure Description
