The anvil support member is attachable to the anvil plate assembly in such a way that when the anvil assembly is coupled to the stapling head of a circular stapler, the staple-forming surface is in substantial registry with the staples supported in the stapling head. A variety of different anvil support members and anvil plate assemblies are disclosed.

  • Patent number: 11793521
    Abstract: In one general aspect, various embodiments of the present invention can include a motorized surgical cutting and fastening instrument having a drive shaft, a motor selectively engageable with the drive shaft, and a manual return mechanism configured to operably disengage the motor from the drive shaft and retract the drive shaft. In at least one embodiment, a surgeon, or other operator of the surgical instrument, can utilize the manual return mechanism to retract the drive shaft after it has been advanced, especially when the motor, or a power source supplying the motor, has failed or is otherwise unable to provide a force sufficient to retract the drive shaft.

  • Patent number: 11793513
    Abstract: A surgical system is disclosed comprising a firing member movable from a proximal position toward a distal position during a firing stroke, a motor configured to drive the firing member toward the distal position, and a control system configured to operate in an open-loop configuration and a closed-loop configuration. In the open-loop configuration, the control system is configured to cause the motor to drive the firing member to a predetermined position between the proximal position and the distal position, determine a time required to drive the firing member to the predetermined position, compare the determined time to a predetermined time, and set a motor velocity of the motor based on the comparison. In the closed-loop configuration, the control system is configured to drive the firing member at the set motor velocity.

  • Patent number: 11793517
    Abstract: A surgical stapling device includes a tool assembly having an actuation sled assembly that includes an actuation sled and a knife movably supported on the actuation sled. The tool assembly includes structure for moving the knife in relation to the actuation sled between extended and retracted positions in response to movement of the actuation sled through a staple cartridge of the tool assembly. Movement of the knife moves a cutting edge of the knife in relation to the actuation sled within a tissue gap defined by the tool assembly to impart a degree of vertical motion to the cutting edge of the knife. This enables the tool assembly to leverage micro-serrations on the cutting edge of the knife to enhance cutting efficiency of the knife.

  • Patent number: 11771454
    Abstract: Various examples are directed to systems and methods for operating a surgical instrument comprising a firing member translatable proximally and distally along a longitudinal axis between a stroke begin position to a stroke end position distal of the stroke begin position; a knife coupled to the firing member; and a motor coupled to the firing member to translate the firing member between the stroke begin position and the stroke end position. A control circuit may receive a firing signal and begin a firing member stroke by providing an initial motor setting to the motor. The control circuit may maintain the initial motor setting for an open-loop portion of the firing member stroke. The control circuit may receive firing member motion data describing a motion of the firing member during the open-loop portion of the firing member stroke and may select a firing control program based at least in part on the motion of the firing member during the open-loop portion of the firing member stroke.
