“…The tissue ablation and damage mechanism is poorly understood and mechanisms for damage minimisation have not been clearly defined. The literature reporting the mechanism of interaction is limited and frequently conflicting (Chan et al, 1986;Bond and Cimino, 1996;Beissner, 1980;Cimino and Bond, 1996). This incompleteness in understanding underpins the reticence of some clinicians to embrace this technology.…”

“…In simplest terms, it is thought that the vibrating ultrasonic tip is used to cut or shatter hard tissue or to cut and emulsify soft tissues Cimino and Bond, 1996;Wells, 1984). Parameters affecting cutting (Khambay and Walmsley, 2000a,b) and removal rate (Chan et al, 1986;Cimino and Bond, 1996;Stumpff et al, 1975), effect of dissipated ultrasonic energy and extent of residual tissue damage (Emam and Cuschieri, 2003;Koch et al, 2003) in individual tissues have been investigated experimentally.…”

“…Moreover, the interaction between ultrasound and living tissue is complex and poorly understood (Chan et al, 1986;Bond and Cimino, 1996;Beissner, 1980;Cimino and Bond, 1996;Cimino, 1999). For tissue applications, ultrasonic instrument design has historically been conducted on a semi-empirical basis, by successive improvement in design during many time-consuming iterative steps (Wiksell et al, 2000).…”

“…In comparison, instruments intended for material cutting such as ultrasonic dental drills, ultrasonic scalpels and bone cutters do not employ integral suction. For commercially available devices, suction pressure is continuous and in the range 550-600mmHg (Chan et al, 1986). The purpose of the suction is claimed to be twofold.…”

“…Stronger tissues with higher collagen content better withstand the vibratory insult from ultrasonic energy and do not fragment, where as weaker tissues will. In comparison to harder tissues, soft tissues are highly compliant and large amplitude and high-frequency vibrations can be used to fragment soft tissue with relative ease (Chan et al, 1986;Amso, 1994). This property is cardinal to the successful design of ultrasonic medical and surgical instruments.…”

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