摘要：
At the surgical tool's proximal end, there is a first means (3) to generateultrasonic vibration in a torsional shear mode. There is also a second means (2)to generate ultrasonic vibration in a longitudinal compression mode. A waveguide (4) is operatively connected to both generating means and extending therefromby a distance of nλ/2 to a distal end provided with cutting and/or coagulatingmeans. The ratio of the wavelengths of the longitudinal compression wave andthe torsional shear wave, λc : λτ, is an odd number. Preferablyλc = N
