  • Publication number: 20220160350
    Abstract: A surgical suturing instrument includes first and second jaw members each defining a hole for detachable receipt of opposite ends of a curved needle. The first jaw member is rotatable relative to the second jaw member to move and transfer the curved needle between the jaw members. A first elongate locking element is slidable within the first jaw member between non-locking and locking positions. When the first elongate locking element is in the locking position and the curved needle is disposed within the hole of the first jaw member, a portion of the first elongate locking element is received in a notch defined in an end of the curved needle to selectively secure the curved needle to the first jaw member.

  • Patent number: 11291443
    Abstract: A surgical apparatus has a clamp and a stapling mechanism. The clamp has a first jaw and a second jaw to clamp on a body tissue at a desired location for a stapling operation. The stapling mechanism is controlled by a trigger handle or a switch assembly. The surgical apparatus has a controller for providing a delay between clamping and actuating of the firing mechanism of the stapling mechanism. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation. The surgical apparatus also has an indicator. The indicator provides feedback about the status of the stapling mechanism and also displays a time of tissue compression by the clamp.

  • Patent number: 10828065
    Abstract: A surgical access system includes a cannula assembly and an obturator assembly. The obturator assembly provides an insufflation channel or fluid passage for delivery of insufflation fluids directly to an underlying cavity, e.g., the abdominal cavity. The fluid passage is completely confined within the obturator assembly isolated from the cannula assembly and terminates at a location distal of the cannula assembly such that the insufflation fluids released from the fluid passage are directed toward the abdominal cavity and not within the cannula assembly.
