    • 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. A method of effecting cutting during a surgical procedure is also provided. In an exemplary embodiment, a surgical tool that is effective to deliver a pressurized stream of fluid through a nozzle is provided, and the pressurized stream of fluid is delivered 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. The fluid that cuts the hard material can include a delivery liquid having a plurality of abrasive solid particles that are formed from an organic material. 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.
    • 提供了一种高压流体喷射系统,可用于在外科手术过程中切割硬质材料。 硬质材料的切割更有效,因为系统用高压流体输送磨料固体颗粒。 还提供了一种在外科手术过程中进行切割的方法。 在一个示例性实施例中,提供了有效地通过喷嘴输送加压流体流的手术工具,并且加压的流体流通过外科手术工具输送到患者体内的硬质材料以进行切割 的患者内的硬质材料。 切割硬质材料的流体可以包括具有由有机材料形成的多个磨料固体颗粒的输送液体。 研磨的固体颗粒可以夹带在加压流体流中,或者加压的流体流可以侵蚀磨料颗粒的固体或悬浮​​液形式。
