Abstract

Energy-based surgical instrumentation (ESI) are surgical devices ablating or cutting tissues via the application of electrical,luminous,acoustic or other energy.High frequency electrotomes are widely used due to the low price,but they produce smoke in the process of surgery and incisions heal slowly.Ultrasonically activated scalpels' cutting performance is satisfying with easily healing incisions while its coagulating capability is poor.Laser scalpels are qualified for both cutting and coagulating in spite of the need of novel technology to overcome the characteristic that tissues absorb laser wavelength selectively.
