Surgical stapling device with lockout system for preventing actuation in the absence of an installed staple cartridge

Surgical stapling instruments surgical stapling cartridges are disclosed. At least one embodiment includes an end effector that has an elongate channel that is configured to operably support a surgical staple cartridge therein and an anvil that is movably supported on the elongate channel between an open position and closed positions in response to an application of opening and closing motions applied thereto. An anvil lock member cooperates with the anvil to retain the anvil in an open position when a staple cartridge has not been installed in the elongate channel and prevent the anvil from moving to a closed position until the staple cartridge has been seated within the elongate channel. Surgical staple cartridges are configured to move the anvil from an open position to an actuatable position when the cartridge has been installed in the end effector.

Motor driven surgical fastener device with cutting member reversing mechanism

A surgical fastener apparatus including a handle, an elongated shaft having a proximal end attached to the handle and a distal end extending therefrom. An end effector comprising a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position, and a cartridge containing a plurality of surgical fasteners, the cartridge attached to the end effector. An electrically powered actuator for deploying the surgical fasteners. An electrically activated reverse mechanism for moving the elongated member from a distal most position within the end effector to a proximal position, the electrically activated reverse mechanism moves the elongated member proximally after the elongated member has moved to the distal most position by moving the trigger to the open position, and wherein after activation of the reverse mechanism proximal movement of the elongated member can be stopped by returning the trigger to its closed position.

SURGICAL INSTRUMENT USAGE DATA MANAGEMENT

A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.

SURGICAL DEVICE

A surgical device is an actuator suitable for coupling to the sleeve (5) of an endostaple with an actuator for a tightening channel (1) and a tightening anvil (2). The tightening channel (1) includes a cartridge (3) with a knife (4) and with at least one line of pushers (8) for the staples on each side of the knife (4). The anvil (2) includes a slot (6) for the knife (4) and at least one line of alveoli (7) on each side of the knife (4), the lines of alveoli (7) corresponding with the lines of pushers (8) for the staples. The number of lines of pushers (8) and the number of lines of alveoli (7) for the staples is different on each side of the knife (4) and the slot (6) respectively.

Surgical stapling device

A surgical stapling device for applying an array of surgical staples to tissue is provided. The stapling device includes an approximation mechanism for moving a cartridge assembly and an anvil assembly between spaced and approximated positions and a firing mechanism for ejecting the array of staples from the cartridge assembly. A single trigger is operable to effect approximation and firing of the device. The device also includes an alignment pin assembly which can be selectively manually or automatically advanced. The anvil assembly includes a stiffener plate which allows the device to have a reduced head portion profile.

Wireless patient monitoring device

A device for obtaining physiological information of a medical patient and wirelessly transmitting the obtained physiological information to a wireless receiver.

Physiological monitor touchscreen interface

A physiological monitor touchscreen interface which presents interface constructs on a touchscreen display that are particularly adapted to finger gestures. The finger gestures operate to change at least one of a physiological monitor operating characteristic and a physiological touchscreen display characteristic. The physiological monitor touchscreen interface includes a first interface construct operable to select a menu item from a touchscreen display and a second interface construct operable to define values for the selected menu item. The first interface construct can include a first scroller that presents a rotating set of menu items in a touchscreen display area and a second scroller that presents a rotating set of thumbnails in a display well. The second interface construct can operate to define values for a selected menu item.

Increasing field of view of reflective waveguide

A near-eye display system includes an image former and a waveguide. The image former is configured to form a display image and to release the display image through a first exit pupil. The waveguide presents a back surface that faces the wearer's eye, and a front surface opposite the back surface. The waveguide is substantially transparent to external imagery received normal to the front surface, and is configured to receive the display image from the image former and to release the display image through a second exit pupil, which is larger than the first exit pupil.

Surgical instrument having a multi-layered drive beam

A surgical instrument including a handle portion, a body portion, a movable handle, a tool assembly, a drive beam and a closure apparatus is disclosed. The movable handle is in mechanical cooperation with a drive member. The tool assembly includes an anvil, a cartridge assembly and a contact surface. The drive beam includes a plurality of layers and at least one layer has a proximal engagement portion and is configured to engage a portion of the drive member. The closure apparatus is configured to engage the contact surface of the tool assembly. At least a partial actuation of the movable handle moves the closure apparatus distally into engagement with the contact surface to approximate the anvil and the cartridge assembly. At least one of the layers of the drive beam is affixed to an adjacent layer of the drive beam via at least one spot weld.

Robotic surgical system with mechanomyography feedback

A robotic surgical system for performing a surgical procedure within the body of a subject includes an elongate surgical instrument, a robotic controller configured to control the motion of the distal end portion of the surgical instrument, and a mechanomyography feedback system in communication with the robotic controller. The mechanomyography feedback system includes a mechanical sensor configured to monitor a physical motion of a muscle and to provide a mechanomyography signal corresponding to the monitored physical motion. Additionally, the feedback system includes a processor configured to receive the mechanomyography signal, to determine if the received signal is indicative of an induced muscle response, and to provide a control signal to the robotic controller if an induced muscle response is detected.
