摘要： This invention discloses an ultrasonic surgical blade, wherein the blade has a curved shape, and both sides of the blade are provided with cutting surfaces, one surface is a concave surface (71) and the other surface is a convex surface (72). The thickness of the blade is gradually thinned along a cutting direction from a proximal end to a distal end. The concave surface length is set as L1, the radius of curvature R1; the length of the convex surface L2, the radius of curvature R2; the angle of the bending of the center line of the blade is α; the diameter of the proximal end of the blade is D; the thickness of the most distal end surface of the blade is T. The relationship among them is: L1=L2+L2/1.5*(D-T)*SIN(α) (1), R1=R2+2T (2). The range of each size is adjustable within 10%. An ultrasonic wave guide and an ultrasonic scalpel using this blade have fewer potential resonant frequencies, so the thermal damage to the tissue is small, and the performance is more stable.

摘要： A transducer for an ultrasonic scalpel, which comprises, from distal end to proximal end of a connecting feature, a fixing feature, a horn, a piezoelectric converting body, a rear-end ring, and a connecting member. By following a design principle of constraints in the parameter relationships between the piezoelectric converting body and the horn in the transducer, a transducer having both appropriate gain and stable performance can be achieved.

摘要： 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); and 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.

摘要： Provided is an ultrasonic surgical knife blade (100). The projection of the blade (100) on a shear plane is banana-like curved shape. From a proximal end to a distal end, the thickness of the blade (100) varies from thick to thin, and then to thick and to thin again. The projection on a vertical shear plane is fruit knife-shaped. The height of the blade (100) varies from high to low, and then gradually decreases, and an arc-shaped cutting groove is formed in the middle position. The present invention allows for an increase of swing amplitude in the bending direction and the effective working length of the blade (100). A boat-shaped (123) or arc-shaped (124) balance cutting groove is provided between the most distant node and a tip of the blade (100), such that the stability of ultrasonic vibration is improved.
