    摘要： A circular stapling device includes an elongate body having a flexible outer tube that supports a reload assembly, a flexible inner cable that supports an anvil assembly, and a flexible central tube that is supported about the inner cable and within the outer tube. The stapling device is configured to access body cavities which cannot be easily accessed by a circular stapling device having a rigid shaft.

    摘要： A surgical system for performing a surgical procedure, the surgical system comprising:
    a surgical device including:
    a housing;
    at least one drive motor disposed in the housing;
    a power source disposed in the housing and configured to provide electrical power to the at least one drive motor; and
    a control circuit coupled to the power source and the at least one drive motor and including a resistor having a resistance associated with a voltage being delivered to the at least one drive motor by the power source, the control circuit configured to calculate a current level across the resistor; and

    at least one loading unit configured for selective connection to the housing of the surgical device, the at least one drive motor configured to actuate the at least one loading unit from a first condition to a second condition, wherein the current level across the resistor changes when the at least one loading unit is in the second condition.

    摘要： A surgical device includes an adapter assembly and a tool assembly that is coupled to the adapter assembly by a pivot member to facilitate articulation of the tool assembly in relation to the adapter assembly. The adapter assembly supports a drive assembly for actuating or firing the tool assembly. The adapter assembly includes an articulation mechanism that adjusts the position of the tool assembly in relation to the drive assembly to compensate for changes in stroke length of the drive assembly that result from articulation of the tool assembly.

    摘要： A surgical stapling instrument includes an elongated handle housing, an elongated body portion extending distally from the handle housing, and an end effector coupled to the elongated body portion and configured to perform an anastomosis. A screw is disposed within the handle housing and has a distal end portion configured to close the end effector about tissue. A rotatable knob is supported by the handle housing and coupled to a proximal end portion of the screw, such that a rotation of the knob results in axial motion of the screw.
