A fluid management system includes a pump connectable to a fluid source. An inflow line removably connects to a cannula for delivering a fluid flow from the pump into a surgical site, such as a joint cavity. A flow pressure sensor is coupled to measure flow pressure in the inflow line and produce a measured pressure value, A controller is connected to the pump and the flow pressure sensor, and the controller maintains a pressure set point by controlling a pump speed based on a backpressure-adjusted pressure value calculated by subtracting a backpressure value selected from a backpressure table from the measured pressure value. The BAPV is monitored to determine whether the BAPV deviates outside an initial BAPV range, and corrective measure are taken should such deviations occur.

A system for tracking a medical device, the system comprising a support having a channel extending therethrough, the channel being defined circumferentially by a surface, at least one encoder configured to track movement of a medical device through the channel, and one or more processors configured to receive input from the at least one encoder, receive an instruction from a user to store a zero position of the medical device relative to the channel, determine relative movement of the medical device from the zero position, and communicate the relative movement of the medical device from the zero position.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. A coupling device driven by a plurality of drive disks corresponds to a first motor and a second motor. One or more processors are configured to send a low torque command to a first motor, send the low torque command to a second motor, determine whether the first motor and the second motor meet one or more hold engagement criteria, send a high torque command to the first motor in response to the first motor and the second motor meeting the one or more hold engagement criteria, and send the high torque command to the second motor in response to the first motor and the second motor meeting the one or more hold engagement criteria.

A surgical stapling assembly that includes a surgical stapling device that has a lockout that is movable between a locked position and an unlocked position. The assembly further includes a staple cartridge with a first cam surface configured to cammingly engage a primary portion of the lockout to move the lockout laterally from the locked position and a second cam surface configured cammingly engage a secondary portion of the lockout to further move the lockout laterally into the locked position when the cartridge is operably seated in the device.

Systems and methods are provided for trajectory guidance during surgical procedures, for example, monitoring and identifying a desired trajectory of surgical access devices and implants for the purpose of preventing unintended injury to surrounding tissues, such as nerves, blood vessels, cartilage, or bone.

An apparatus (100) for guiding a surgical needle with improved accuracy. The apparatus (100) having a base (1) for positioning the apparatus (100) on a patient; a second arc member (6) attached to the base (1); a first arc member (4) moveably attached to the second arc member (6); an arm (2) attached to a needle guide support (3) at one end and moveably attached to the first arc member (4) at a distal end, and an angle marking device (7) attached to the arm (2) to indicate a vertical reference point for measuring the angle of tilt of the arm (2) from the vertical reference point relative to the base (1). Wherein the first arc member (4) is configured to move on the second arc member (6) to facilitate movement of the needle guide support (3) in a cranio-caudal plane and the arm (2) is configured to move on the first arc member (4) to facilitate movement of the needle guide support (3) in an axial plane.

A method of initializing the layout of one or more robotic arms controllable by an input object, comprising: entering a paused mode, in which control of movement of the robotic arms by the input object is paused; measuring an input object initialization layout, defined by the layout of at least one segment of the input object; actuating at least a portion of the robotic arms to match the input object initialization layout; and entering a controlled mode, in which movements of the input object control the robotic arms.

Provided is an operation input device for inputting a manipulation command to a manipulator having an end effector for observing or medically treating an affected site. The operation input device includes a grip section that is holdable by changing a method of holding the grip section with the same hand of an operator and an operating section that is provided in the grip section and that is operated with a single finger, which is the same before and after the holding method is changed, so as to manipulate a main function of the end effector.

A surgical instrument comprises an arm. A first member is movable relative to the arm and gravity responsive to define a first orientation of the arm. A lock is engageable with the first member. A second member is movable relative to the arm and gravity responsive to measure an angle of a second orientation of the arm relative to the first orientation. Systems and methods of use are disclosed.

A computer-assisted surgery system may have a robotic arm including a surgical tool and a processor communicatively connected to the robotic arm. The processor may be configured to receive, from a neural monitor, a signal indicative of a distance between the surgical tool and a portion of a patient's anatomy including nervous tissue. The processor may be further configured to generate a command for altering a degree to which the robotic arm resists movement based on the signal received from the neural monitor; and send the command to the robotic arm.
