  • Patent number: 12137907
    Abstract: A handle assembly for a surgical stapler can comprise a rotatable actuation shaft. The actuation shaft can have a first rotational orientation in which it can actuate a jaw assembly in a repeatable open and close mode, a second rotational orientation in which it can actuate a jaw assembly in a staple firing mode, and a third rotational orientation in which it can actuate a jaw assembly in a reversing mode. The handle assembly can include a rotational mechanism arranged to discretely position the rotatable actuation shaft in one of the rotational orientations. The rotational mechanism can be arranged for single handed operation such as by including a slidable switch or selector to rotate the actuation shaft.

  • Publication number: 20240041457
    Abstract: A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle can include a manual return mechanism.

  • Publication number: 20230338025
    Abstract: A surgical stapling system can include a reload shaft. The shaft can include an elongate tubular member with have a jaw assembly at the distal end thereof and a coupling collar at the proximal end thereof. The shaft assembly also includes an articulation joint coupling the jaw assembly to the distal end. A drive member and an articulation member extend within the tubular body of the shaft from the proximal end to the distal end. A firing member is connected to the distal end of the drive member such that advancement of the drive beam advances the firing member to close the jaw assemblies and fire staples from a reload positioned in the jaw assembly. The shaft assembly can also include a lockout mechanism to prevent a firing operation on a previously-fired reload or no reload.
