    摘要： A surgical instrument, such as a surgical cutting and fastening instrument, with an automatically articulatable end effector. The surgical instrument may comprise an end effector, a shaft, and an articulatable joint assembly connected between the end effector and the shaft. The joint assembly comprises at least one motor for articulating the end effector relative to the shaft. The joint assembly comprises at least one articulation sensor for sensing articulation of the end effector relative to the shaft. The instrument further comprises a control unit in communication with the articulation sensor and the motor. The control unit comprises at least one memory unit for storing articulation data from the at least one articulation sensor. When activated, the control unit sends control signals to the motor of the joint assembly to articulate automatically the end effector to a desired position based on the articulation data from the articulation sensor that is stored in the memory unit of the control unit.

    摘要： An end effector for a surgical cutting and stapling instrument. In various embodiments, the end effector may include an elongate channel that is configured to support a staple cartridge therein and which is also operably coupled to a surgical cutting and stapling instrument. An anvil may be movably supported relative to the elongate channel for selective movement between an open position and a closed position wherein tissue is clamped between the anvil and a staple cartridge supported within the elongate channel in response to a closing motion applied thereto from the surgical cutting and stapling instrument. At least one light source may be provided on at least one of the staple cartridge and the elongate channel. The light sources may interface with the anvil to provide a visual indication viewable through a portion of the anvil to indicate a position of tissue clamped between the anvil and the staple cartridge.

    摘要： A system and method of sensing temperature at an optical fiber tip, including the steps of positioning a slug of fluorescent material adjacent the optical fiber tip, providing an optical stimulus having a wavelength within a first predetermined range through at least one fiber optically linked to the optical fiber tip, wherein a desired optical fluorescent response having a wavelength within a second predetermined range from the fluorescent slug is generated, detecting a signal representative of the optical stimulus, detecting a signal representative of the optical fluorescent response, digitally processing the optical stimulus signal and the optical fluorescent response signal to determine a phase difference therebetween, and calculating a temperature for the optical fiber tip as a function of the phase difference. The phase difference between the optical stimulus signal and the optical fluorescent response signal may be determined directly or indirectly as a function of the phase difference between a reference signal and the optical stimulus signal and the phase difference between the reference signal and the optical fluorescent response signal.
