    摘要: A motor-driven surgical cutting and fastening instrument that comprises an end effector, a shaft connected to the end effector, and handle connected to the shaft. The end effector may comprise a cutting instrument that, when actuated, longitudinally traverses the end effector to cut tissue clamped in the end effector. The handle may comprise an electric motor for actuating the cutting instrument and a motor control circuit for controlling the motor. The motor control circuit may comprise a power source connected to the motor for electrically powering the motor and a current control circuit, connected to the power source, for varying the current supplied to the motor from the power source. The current control circuit may vary the current supplied to the motor, and consequently, the output torque supplied by the motor, such that the motor has at least (i) a first, low power operational mode for a first portion of a cutting stroke cycle of the cutting instrument, and (ii) a second, high power operational mode for a second portion the cutting stroke cycle of the cutting instrument.

    摘要: In various embodiments, a surgical test device for a surgical tool, such as a severing and/or sealing tool (e.g., a surgical stapler), is provided. In at least one embodiment, the surgical tool can be configured to supply at least one actuation motion to an end effector. The actuation motion(s) may cause a cutting member to move within and/or sealing members (e.g., staples) to eject from the end effector. Further, in at least one embodiment, the surgical test device can be releasably engaged to a portion of the surgical tool, such as the end effector. Additionally, the surgical test device can be configured to permit the surgical tool to supply the actuation motion(s) while preventing the tool from performing its intended surgical function. Accordingly, the surgical tool may be test fired without wasting a sealing member cartridge, while preventing inappropriate use of the tool when the test device is attached thereto.
