A tissue resecting or other medical device includes a handle coupled to an elongated shaft. A radiofrequency (RF) electrode is carried at a distal end of the elongated shaft, and the electrode is moveable across a window in a sleeve or other component of the shaft. The shaft has an interior channel connectable to a negative pressure source to remove debris from the channel. A motor is carried by the handle and operatively coupled to the electrode for moving the electrode relative to the window. An electronic image sensor and lens are disposed at a distal end of the shaft, and a plurality of conductors may extend through the shaft to the image sensor. The image sensor, lens and sensor conductors are disposed within a first tubular member, and an LED or other light source is also positioned at a distal end of the shaft with LED conductors or leads extending through a second tubular member of the shaft to the LED.

A tiered multi-display control scheme may provide various communication control options for a surgeon-controlled secondary display and primary operating room display. A powered surgical tool may be in operative communication with a local display and at least one main monitor within the operating room outside the sterile field for displaying multiple data and/or imaging sources. The local display may be interactable by the surgeon within the sterile field. The display outside the sterile field may show an image of an aspect of the laparoscopic scope and may contain superimposed other data streams from other devices besides the scope. The secondary display could be used to direct from its displayed content up onto the primary display or remove it from the display. The added or removed data streams may be originated from the secondary display, passed through the secondary display, or be networked with the secondary display.

The present invention relates to an electrosurgical device wherein a surgical instrument is connectable to a handpiece via a connection hub, the connection hub facilitating an electrical and mechanical connection therebetween. The connection hub is configured to implement a cam-follower mechanism for securing an electrical connection between the surgical instrument and a handpiece configured to receive the surgical instrument. As a result of such a configuration, the electrical connection can be established in a more efficient manner compared to prior art implementations.

Certain aspects relate to systems and techniques for a patient platform system that includes a table and one or more kinematic chains that are coupled to the table. The table includes a rigid base and a table top that is movable relative to the rigid base. One or more processors initiate first movement of the table top relative to the rigid base in accordance with a user request, and move the one or more kinematic chains relative to the rigid base in coordination with the first movement of the table top such that one or more preset conditions are maintained during the first movement of the table top.

A system for validating data purportedly generated in a medical procedure is disclosed. The system includes a medical hub, at least one remote server communicatively coupled to the medical hub, and a medical instrument communicatively coupled to the medical hub. The system is configured to access the data, validate the data to determine if the data is validly generated by the medical procedure, determine that the data contains at least one flaw or error, and improve data integrity by preventing the at least one flaw or error from being integrated into a larger dataset associated with the at least one remote server.

In general, devices, systems, and methods for surgical device activation detection using current sensing are provided. In an exemplary embodiment, a surgical system includes a surgical pump, a detector, and a surgical device. The detector is configured to sense changes in electrical power in an AC power line from an AC power source to the surgical device to detect activation of the surgical device. In response to the detection activation, the pump can properly provide suction pressure to the surgical device to allow the surgical device to provide aspiration at a surgical site during performance of a surgical procedure.

An electrode assembly for an electrosurgical instrument includes an active electrode and retainer arrangement that are inserted to a cavity of an insulator and then welded together to secure the active electrode in the insulator for use in tissue treatment. The active electrode and retainer are configured to interlock with at least one internal retention surface of the cavity. Once assembled in the cavity, both the active electrode and the retainer may have a portion that extends out of the cavity to protrude from the insulator. This allows opposing biasing forces to be exerted on the active electrode and the retainer respectively so as to push the two components against a retention surface within the cavity. When the active electrode and the retainer are welded together, any clearance with the retention surfaces inside the cavity, caused by variations between parts during the manufacturing process, is removed or at least minimized.

An electrosurgical instrument end effector comprises a rotary shaver arrangement, and an active electrode for supplying radio-frequency (RF) power to a surgical site. The rotary shaver arrangement comprises a rotatable shaver blade, and a stator that partially surrounds the rotatable shaver blade. At least part of the stator is electrically non-conductive.

A suction device and system utilizing a moveable and/or portable dry vacuum accumulator for vacuum accumulation. The device has at least one accumulator or reservoir for storing a vacuum charge. The device is initially charged by a vacuum source, such as a vacuum from a wall vacuum source as is conventional in a hospital. The vacuum may be boosted using a vacuum boosting pump that may be pneumatic, hydraulic or even electric. The device can be charged to a second predetermined vacuum level which can be different from both atmospheric pressure as well as a first predetermined vacuum level supplied by the vacuum source. Apparatus is also provided for boosting vacuum or for increasing or decreasing a volume in the at least one accumulator or reservoir.

A probe for ablating tissue comprises an electrosurgical working end configured to provide a first plasma about a first surface location and a second plasma about a second surface location, the first plasma having first ablation parameters and the second plasma having second ablation parameters. The probe has a working end with a thickness below 3 mm and produces a low temperature plasma.
