Abstract
To carry out a mucosa resection, a liquid is injected beneath a tissue which is then separated by means of mechanical or electrosurgical equipment. A device is provided that includes a facility for endoscopic water-jet surgery with a control device for regulating a pressure at which a water jet is discharged from a nozzle of the facility to obtain a predetermined amount of energy. An adjusting assembly is provided for setting the pressure to a first value and to a second value. The first value is so chosen that the water jet penetrates a mucosa in such a way that the mucosa is lifted from an underlying muscularis through formation of a fluid deposit. The second value is adjusted and different from the first value in such a way that the mucosa is sectionally cut through by the water jet.
Claims11
A device for endoscopic mucosa resection, comprising:
- a facility for endoscopic water-jet surgery comprising a nozzle for discharge of a fluid jet;
- a control device for regulating a pressure with which the fluid jet discharged from the nozzle to obtain a predetermined amount of energy;
- an adjusting means for setting the pressure of the fluid jet to a first pressure value, at which the fluid jet penetrates a mucosa to lift the mucosa from an underlying muscularis by formation of a fluid deposit, and to a second pressure value, different from the first pressure value, at which the fluid jet sectionally cuts through the mucosa;
- and
- a first starting switch, wherein the adjusting means is configured to discharge a predetermined amount of the fluid from the nozzle when the pressure is set to the first pressure value and the first starting switch is actuated.
