ABSTRACT:
The invention relates to a fluid jet device for producing a liquid used to remove, in particular, biological tissue. The fluid jet device comprises housing in which a pump set is arranged for producing high liquid pressure within a range of up to 800 bars. A pressure supplying source and the nozzle which produces the liquid jet can be connected to the pump set, the nozzle being connected by a flexible connecting line. The hole diameter of the nozzle outlet measures between 20 to 120 micrometers. The weight of the housing with the pump set and the separate pressure supplying source for the pump set respectively is such that they are especially suitable for mobile use and can therefore respectively be carried by hand.
