    摘要： An imaging probe is covered with a stiff sheath, which allows the imaging probe to move while the stiff sheath remains in a substantially fixed location for at least a portion of the surgical procedure while the probe moves within the stiff sheath. The stiff sheath may comprise sufficient stiffness to resist deformation as the imaging probe moves along an internal channel of the sheath. The sheath can be sized and shaped in many ways and may comprise one or more openings to allow fluid to move within the channel in which the probe is located.

    摘要： An energy source is coupled to a probe mounted on a robotic arm, and a processor configured with instructions to release energy to resect tissue in coordination with movement of the robotic arm and probe. The tissue can be resected in accordance with a defined tissue resection volume that can be determined based on images of the patient. The probe can be moved to a plurality of positions with movement of a distal end of the robotic arm and tissue resected in accordance with the treatment plan. The distal end of the robotic arm can be configured to move to a plurality of locations and orientations to provide an appropriate position and orientation of the probe tip and energy source. The processor can be configured with instructions to pivot the probe at a location to decrease tissue movement near the pivot such as an internal location of the patient.

    摘要： An apparatus is configured to provide hemostasis with tissue removal in order to inhibit one or more of blood loss or tissue drainage. In many embodiments, a nozzle releases a liquid jet in a liquid medium in order to provide cavitation and a plurality of shedding pulses. The liquid jet, its cavitation and the plurality of shedding pulses can affect vascular tissue in order to promote clotting in order to inhibit bleeding. In many embodiments, vessels of the vascular tissue are affected at a distance from a region where cavitation of the water jet contacts the tissue. In many embodiments, the cavitation and plurality of shedding pules are related to a pulsatile shear wave propagating along the blood vessel that is related to clot promoting changes of the blood vessel.
