Process for generating a pulsatile stream of a pulsed-suctioned sterile fluid jet and resulting pulsed jet for a handpiece, in particular for surgical use

摘要

The process consists in generating a firing pulse pattern characterized in that it implements a pressurized liquid channel and a pneumatic aspiration channel and in that the periodic firing of the pressurized jet is controlled during the periodic application of aspiration and in that the tension on the tissue is released during the cutoff of the aspiration by aeration.;A variant of the process enables obtaining, even in the case of a high repetition rate, a steep trailing edge of the firing pulse, by means of establishment of communication with the exterior of the pressurized liquid feed line near the time of the cutoff of the feeding of the liquid.;This invention is of interest to manufacturers of surgical and medical instruments and handpieces for interventions using a pressurized liquid jet.
