High-power low-frequency ultrasound: A review of tissue dissection and ablation in medicine and surgery

摘要: Abstract High-power low-frequency ultrasound in the range 20–60 kHz has wide ranging clinical applications surgical and medical instruments for biological tissue cutting, ablation or fragmentation, removal. Despite widespread application common device operating characteristics, there is an incomplete understanding of mechanism failure, removal damage. The relative contribution cavitation, direct mechanical impact thermal effects to each process specific types remains unclear. Different distinct mechanisms rates are observed interaction with soft hard types. Device parameters known affect include frequency, peak–peak tip amplitude, suction time. To date, been little analysis effect variations in, interactions of, these on damage individual Potential controllable occurring tissues alteration global biomechanical properties, histomorphological changes, protein denaturation necrosis. This paper presents a critical review literature application, interaction, residual It describes
