  • Publication number: 20190209166
    Abstract: A tool assembly for a surgical stapling device includes a channel member for supporting a staple cartridge therein and an anvil to deform a plurality of staples ejected from the staple cartridge thereagainst. The tool assembly also includes a sled which is movable to force the staples from the cartridge against the anvil to staple tissue disposed between the anvil and the staple cartridge. A dynamic clamping member is included which has a pin which movably engages the anvil and a flange which movably engages the channel assembly. The dynamic clamping member is mounted to and movable with the sled. The pin and the flange of the dynamic clamping member cooperating to oppose the forces associated with clamping and stapling tissue and also to maintain a substantially uniform gap between the anvil and the staple cartridge during stapling of the tissue.

  • Patent number: 10342538
    Abstract: A surgical device comprising a first jaw member, a second jaw member, a clamping member and a clamp apparatus is disclosed. The clamping member is slidably positioned to translate at least partially through the first jaw member. The clamping member engages the first jaw member and the second jaw member, and has a knife blade for cutting tissue. A flange of the clamping member is configured to engage a cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position. The clamp apparatus is movable from a retracted position to an advanced position for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance. The clamping member and the clamp apparatus are separately movable.

  • Publication number: 20190083088
    Abstract: A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes.

  • Publication number: 20160073347
    Abstract: In embodiments of device proximity detection implemented in hardware, a computing device, such as a mobile phone, appliance device, or other electronic device can be implemented with wireless radio systems for wireless communications, and a wireless radio system receives a wireless signal. A computing device includes a radio controller of the wireless radio system, and the radio controller is implemented to detect an indication associated with the wireless signal, such as a byte pattern in the wireless signal and/or a signal strength of the signal. The radio controller can then determine that the indication of the wireless signal identifies the wireless signal as pertinent to an application executing on the computing device, and communicate an event notice to a signal manager that the wireless signal has been identified. The radio controller communicates event notices via a hardware interface that is implemented to interface the radio controller with the signal manager.
