Abstract
A method of pin-pointing a fluid jet onto a target involves pumping fluid at a low pressure through a jet creating instrument, directing the low pressure jet onto a target and pumping the fluid at a higher pressure while maintaining the jet on the target.
Claims8
A method of pin-pointing and cutting a target with a fluid jet, comprising the steps of:
- providing a fluid jet system including a variable pressure pump, a source of fluid in communication with the pump, a delivery tube in communication with an outlet of the pump and an instrument in communication with the delivery tube having an orifice for creating a fluid jet as the pumped fluid exits therefrom;
- pumping fluid at a low pressure through the instrument to create a low pressure jet;
- directing the low pressure jet onto a target to pinpoint the target to be cut;
- pumping the fluid at a higher pressure while maintaining the jet on the target;
- wherein cutting of the target is achieved at the higher pressure, while the jet at the lower pressure is unable to cut the target.
