    摘要： A surgical instrument with a tissue-clamping end effector, where actuation of the instrument is locked out when the thickness of the tissue clamped in the end effector is not within a specified thickness range. The end effector may comprise a tissue thickness module that senses the thickness of the tissue clamped in the end effector. The surgical instrument also comprises a control circuit in communication with the tissue thickness module. The control circuit prevents actuation of a working portion of the end effector when the thickness of the tissue clamped in the end effector is not within the specified thickness range.

    摘要： A surgical cutting and fastening device is disclosed including a handle assembly, a power supply, and a control circuit. The handle assembly includes a motor configured to drive a cutting member. The control circuit operably couples the power supply and the motor. A firing switch allows the power supply to provide power to the motor in a first energizing direction. A forward control circuit is configured to control current flow from the power supply to the motor. The forward control circuit includes a first flow path and a second flow path including a power control switch. The power control switch prevents current from flowing through the second flow path. The power control switch allows current to flow through the first flow path and the second flow path. A reverse flow path is configured to allow the power supply to provide power to the motor in a second energizing direction.

    摘要： A method is provided for rerouting flow through the small intestine of a patient with an implanted artificial sphincter that encircles a portion of the small intestine. The small intestine includes a duodenum, a jejunum extending from the duodenum, and an ileum extending from the jejunum. The method includes providing the artificial sphincter in an open state to thereby permit intestinal flow through the encircled portion of the small intestine such that the intestinal flow passes through the duodenum, the jejunum, and the ileum. The method further includes, in response to a user-activated electrical input, transitioning the artificial sphincter to a closed state to constrict the encircled portion of the small intestine and thereby redirect intestinal flow from a first portion of the small intestine to a second portion of the small intestine such that the intestinal flow bypasses at least a portion of the jejunum.

    摘要： A method of controlling motor velocity in a surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer coupled to the control circuit. The method includes receiving a first position of a displacement member from a position sensor, starting a timer, advancing the displacement member to a second position by setting a motor velocity to a first velocity, receiving the second positon from the position sensor, stopping the timer when the displacement member reaches the second position, receiving elapsed time from the timer, wherein the elapsed time is the time taken by the displacement to move from the first position to the second positon, and controlling, by the control circuit, velocity of the motor based on the elapsed time.
