A surgical robotic system comprising: a robotic arm; a tool drive coupled to the robotic arm; a cannula interface configured to couple a cannula to the tool drive, the cannula interface having a fluid pathway in communication with an interior lumen of the cannula; and an insufflation pathway coupled to the robotic arm, the insufflation pathway having a distal end coupled to the fluid pathway and a proximal end coupled to a surgical insufflator.

An energy delivery probe is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the energy can be applied with a vapor media. The energy delivery probe can include a vapor delivery member configured to extend into a transition zone prostate tissue. A condensable vapor media can be delivered from the vapor delivery member into the transition zone tissue, wherein the condensable vapor media can propagate interstitially in the transition zone tissue and be confined in the transition zone tissue by boundary tissue adjacent to the transition zone tissue. Methods associated with use of the energy delivery probe are also covered.

A method of reducing retro-repulsion of a stone during a laser lithotripsy procedure involves the use of a spacer tip or standoff sleeve to create a passage between the tip of a fiber and a stone, and to prevent collapse of a bubble formed by vaporization of and/or gas pressure on liquid present in the passage. The laser radiation may consist of continuous or quasi-continuous wave radiation that is relatively low in power compared to the therapeutic pulses, or may consist of the therapeutic pulses if the pulse frequency is high enough to prevent collapse of the bubble between pulses. The spacer tip or standoff sleeve further prevents collapse of the bubble and ingress of liquid into the laser path. The spacer tip or standoff sleeve may be a generally-cylindrical protective cap that is fitted to an end of the optical fiber and that extends beyond the fiber tip to provide a predetermined spacing or standoff between the fiber tip and the stone when the protective cap is in contact with the stone. Alternatively, the spacer tip or standoff sleeve may be a catheter sleeve that permits axial adjustment of fiber position within the sleeve.

An electrosurgical device is adapted for use through a port and within a body cavity. The device includes a gas supply supplying gas to a distal tip and a valve to regular such supply, and an electric supply for supplying electricity to the distal tip. A pressure relief system is provided to regulate an outflow of gas from within the body cavity to prevent exceeding a predetermined pressure. The inflow of the gas through the valve and outflow of gas through the pressure relief system may occur simultaneously.

The present disclosure provides systems, devices, and methods for penetrating a biological membrane. The system may comprise a laser unit configured to generate one or more laser beams. The system may comprise a set of targeting optics configured to direct the one or more laser beams to a target region of the biological membrane. The system may comprise a raster scanner operatively coupled to the laser unit and the set of targeting optics. The system may comprise a non-transitory computer readable storage medium comprising a set of instructions. The set of instructions may be configured to control at least one of the laser unit, the set of targeting optics, or the raster scanner to photodisrupt the target region of the biological membrane to a target depth while minimizing damage to one or more blood vessels in proximity to the target region.
