  • Patent number: 11006954
    Abstract: Adjuncts for use with surgical instruments, such as staplers, are provided. In one embodiment, an adjunct can include a plurality of suction members configured to attach the adjunct to an end effector jaw of a surgical stapler using a suction force. The suction members can be configured to generate the suction force when compressed. The suction members can be further configured to release the suction force to decouple the adjunct from the end effector jaw, permitting deployment of the adjunct at a treatment site. In certain embodiments, the suction members can include a plurality of air pockets formed in the bulk of the adjunct or within protrusions extending outward from a surface of the adjunct. The air pockets can be in communication with corresponding openings allowing air to escape the air pockets when compressed.

  • Patent number: 11005291
    Abstract: A surgical instrument includes a handle, an adaptor, and a non-contact electrical interface. A proximal end of the adaptor is releasably coupled to a distal end of the handle. The non-contact electrical interface is configured to wirelessly transmit energy from the handle to the adaptor and is configured to wirelessly transmit data from the adaptor to the handle. The electrical interface may include a proximal coil disposed within the handle and a distal coil disposed within the adaptor. When the adaptor is coupled to the handle, the proximal coil may be disposed adjacent the distal coil to form a transformer to inductively transfer energy from the handle to the adaptor and inductively transmit data from the adaptor to the handle.

  • Patent number: 11000281
    Abstract: The invention is an inserter for a staple having a bridge member and opposing open legs and the inserter holds the staple between a pair of cylindrical expanders which splay apart in response to a camming mechanism having a pair of followers that carry the expanders. The followers are activated as they are drawn over the camming ramp in response to a trigger action. The ramp also includes a detent which alerts the user that the staple is engaged in an activated position, and a safety that keeps the followers from returning to the un-loaded position.

  • Patent number: 10993717
    Abstract: A surgical stapling system is disclosed comprising an end effector configurable in an open configuration and a clamped configuration. The end effector comprises a firing member that moves toward an ending position in response to a firing motion. A sensor is configured to produce a signal corresponding to the configuration of the end effector. A rotatable drive screw is drivable by an electric motor and is threadably engaged with the firing member such that rotary motion is converted to the firing motion. A control system is configured to evaluate the signal produced by the sensor and allows the electric motor to provide the firing motion to the firing member if the end effector is in the clamped configuration. The control system does not allow the electric motor to provide the firing motion to the firing member if the end effector is in the open configuration.

  • Patent number: 10993714
    Abstract: A trigger mechanism for a surgical instrument, particularly, a surgical stapling instrument provides significant mechanical advantages by increasing the length of the firing stroke of the surgical instrument while reducing the degree of movement of the trigger associated with the trigger mechanism. The trigger mechanism also reduces the forces required to actuate the trigger thereby enhancing usability and minimizing operator fatigue.
