Abstract
A high pressure fluid jet system is provided, which is useful for cutting hard material during a surgical procedure. The cutting of hard material is more efficient as the system delivers abrasive solid particles with the high pressure fluid. In an exemplary embodiment, abrasive solid particles can be mixed with a pressurized stream of fluid prior to delivery of the fluid to a nozzle of an application tool. Alternatively, the abrasive solid particles can be entrained in the pressurized fluid stream or the pressurized fluid stream can erode a solid or suspension form of the abrasive particles.
Claims17
A method of effecting cutting during a surgical procedure, comprising:
- providing a surgical tool effective to deliver a pressurized stream of a fluid through a nozzle;
- and
- delivering the pressurized stream of fluid through the surgical tool and out of the nozzle to hard material within a patient to effect cutting of the hard material within the patient in a desired pattern such that the fluid that cuts the hard material includes a delivery liquid having a plurality of abrasive solid particles formed from an organic material.
A system for cutting tissue during a surgical procedure, comprising:
- a surgical apparatus effective to deliver a stream of pressurized fluid;
- and
- a plate having a cutting template having a region formed of a solid material resistant to erosion by the pressurized fluid and an opening in said region, the opening being occluded by a plug of abrasive material.
