A surgical treatment apparatus comprises an elongate support, an elongate tube, and a movable endoscope having a stiff distal portion, in which the stiff distal portion of the endoscope is configured to move one or more components of the apparatus when the support remains substantially fixed. The support may comprise a plurality of spaced apart aspiration openings near the distal end in order to facilitate alignment with the treatment site. In many embodiments, an image guided treatment apparatus is configured for use with an imaging device. In many embodiments, a target resection profile is provided. The target resection profile and one or more tissue structures are displayed on an image, and the target resection profile displayed on the image is adjusted with user input.

A user interface presents a 3D view of the tissue and treatment plan. The 3D view comprises a plurality of transverse images arranged along a one or more longitudinal images. The user adjusts the treatment profile with input to the user interface, and an updated treatment profile is shown on the other views. The user to one or more of zoom, pan, or rotate the 3D view with the treatment profile overlaid on the 3D view, and the treatment profile moves with the 3D view to maintain registration with the 3D view. In some embodiments, a 3D treatment plan is generated in accordance with a plurality of angles between a treatment probe and the one or more tissue structures. An AI algorithm can be used to identify tissue structures and plan the treatment angles and energy delivery in accordance with the tissue structures, which can provide a more customized treatment.

An apparatus to treat a patient, the apparatus comprises a carrier having a proximal end and a distal end, an optical fiber to couple to a light source, a fluid delivery element comprising a nozzle having an orifice on the distal end, and an alignment structure to align the optical fiber with the orifice. A distance extends between the alignment structure and the orifice, such that the light beam emitted from the optical fiber diverges so as to allow energy transmission and fluid flow through the orifice. In some embodiments, the apparatus to ablate tissue comprises a source of pressurized fluid, and the nozzle is coupled to the source of pressurized fluid to release a fluid stream.

A fluid source on a carrier is configured to rotate relative to a probe to direct a fluid stream from the source toward an opening of an evacuation lumen. This may help to remove material that may collect near the opening, such as blood clots and tissue. Also, directing the fluid stream toward the evacuation lumen can draw flowable material from the surgical site toward the evacuation lumen to improve removal of material from the surgical site.

A fluid stream is directed toward tissue to generate a plurality of shedding clouds. The fluid stream can be scanned such that the plurality of shedding clouds arrive a different overlapping locations. Each of the plurality of shedding clouds can remove a portion of the tissue. In many embodiments, an apparatus to ablate tissue comprises a source of pressurized fluid, and a nozzle coupled to the source of pressurized fluid to release a fluid stream, in which the fluid stream generates a plurality of shedding clouds.

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.

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.

A surgical treatment apparatus comprises a waterjet configured to fragment tissue and provide intact cells such as stem cells with the fragmented tissue. The intact cells can be used in one or more of many ways such as for genetic or other testing, and the intact cells can be identified as stem cells. In many embodiments, the intact cells comprise stem cells. In many embodiments, a waterjet is configured to fragment tissue. The fragmented tissue can be collected with a filter having pores sized smaller than the tissue fragments. In many embodiments cavitation with a waterjet is used to fragment the tissue comprising the intact stem cells. The waterjet may comprise a waterjet immersed in a liquid comprising water so as to form a plurality of shedding pulses. The plurality of shedding pulses can be generated with a frequency sufficient to fragment the tissue. The shedding pulses can generate cavitations that fragment the tissue.

Described is an arrangement with an ultrasonic rod probe for carrying out rectal or vaginal examinations, having a distally rounded probe head, at least in which an ultrasonic transducer is integrated. The invention is distinguished by the fact that attached to the probe head is at least one pressure-sensitive element which, in response to mechanical contact with an object, undergoes deformation when a pressure acting between the pressure-sensitive element and the object is exceeded.
