Title:
ULTRASONIC SCALPEL BIT
Document Type and Number:
WIPO Patent Application WO/2023/142526
Kind Code:
A1
Abstract:
An ultrasonic scalpel bit (100), comprising a bit body (113) in a flat structure, two symmetrical end faces (106) being respectively provided in the thickness direction. At least one side of each end face (106) is provided with a cutting part (131) in the axial direction thereof; the cutting part (131) comprises a surface (132), at least two saw tooth rows (102) being provided on the surface (132), and each saw tooth row (102) being formed by arranging a row of saw teeth (103) in the axial direction of the bit body (113); a cutting direction of the saw teeth (103) is parallel to the axial direction of the bit body (113), and the saw tooth rows (102) are arranged side by side at intervals; a cooling channel (133) is provided between the adjacent saw tooth rows (102). The cooling channels (133) having a flow guide effect extend from the proximal end of the bit body (113) to a tip part at the distal end, thus guaranteeing that cooling water can be effectively transferred to the tip so as to achieve a good cooling effect on tissue at a deep position. The cooling channels (133) are close to the saw teeth (103) so that heat exchange can be performed quickly.
