Abstract
Abstract The pressurized liquid dissection apparatus has means for pressurization of working liquids and treatment liquids, controlled discharge means for a pressurized jet, and means for switching or mixing a treatment product with the working liquid or multiplexing means during pulsed mode operation of pressurized pulsed jets. The procedure consists in pressurized spraying of at least one treatment product with the pressurized surgical working jet or separately therefrom but with the same apparatus and during the same intervention so as to realize a surgical act and a therapeutic act during one and the same intervention. This invention is applicable in the surgical and medical fields.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
88 words
Procedure of surgical or medical intervention on the body of a living being using a surgical or medical apparatus of which the working fluid is a pressurized biocompatible liquid, characterized in that, during the course of the intervention and with this same apparatus, at least one treatment product, mixed or not with the working liquid, thus improving its penetration and diffusion into the tissues, is sprayed under pressure in order to realize in a single intervention and with the same apparatus a surgical act and a therapeutic act.
Claim 2
Dependent Claim
88 words
Procedure of surgical or medical intervention on the body of a living being using a surgical or medical apparatus of which the working fluid is a pressurized biocompatible liquid, characterized in that, during the course of the intervention and with this same apparatus, at least one treatment product, mixed or not with the working liquid, thus improving its penetration and diffusion into the tissues, is sprayed under pressure in order to realize in a single intervention and with the same apparatus a surgical act and a therapeutic act.
