    摘要: A surgical apparatus includes an end effector configured to interact with a tissue during a plurality of zones of operation. The surgical apparatus further includes at least one drive mechanism operable to effect at least one motion in the end effector during each of the zones of operation. The surgical apparatus also includes one or more vibration sensors configured to record vibrations generated by the at least one drive mechanism during the zones of operation, wherein the one or more vibration sensors are configured to generate an output signal based on the sensed vibrations, and wherein the output signal is employed to determine a status of the surgical apparatus based on predetermined threshold values that are unique to each of the zones of operation.

    摘要: Various surgical tools with bailout mechanisms are provided that allow direct engagement with one or more actuators to provide rapid and effective bailout (such as release, reversal, and/or retraction) of surgical tools while minimizing the amount of force and/or time to complete the bailout. Robotic surgical tools generally have a housing and an elongate tool shaft extending from the housing and having an end effector on a distal end thereof. The housing has a plurality of actuators for causing various functions of the end effector, such as rotation, articulation, clamping, firing, stapling, etc. The housing attaches to a tool driver on a robotic arm that electromechanically drives the actuators to control the end effector. A bailout mechanism can extend from the housing into the elongate shaft and directly engage the actuators to apply a force thereto to retract an actuator.

    摘要: A surgical instrument includes a motor operably coupled to a firing member, wherein the motor is configured to generate at least one rotational motion to motivate the firing member to cause staples to be deployed during a firing stroke. The surgical instrument includes a primary processor configured to determine a first acceleration of the firing member during the firing stroke, and compare the first acceleration to predetermined threshold acceleration. The surgical instrument also includes a secondary processor configured to determine a second acceleration of the firing member during the firing stroke, and compare the second acceleration to the predetermined threshold value.

    摘要: A staple cartridge comprises an outer tissue-contacting surface comprising at least one first staple cavity. The at least one first staple cavity is configured to receive at least one first staple that includes a first staple leg with a first tip protruding beyond the outer tissue-contacting surface when the at least one first staple is in an unfired position. The staple cartridge includes an inner tissue-contacting surface comprising at least one second staple cavity. At least one pocket extender protrudes from the outer tissue-contacting surface, wherein the at least one pocket extender is configured to conceal the first tip when the at least one first staple is in the unfired position. The inner tissue-contacting surface cooperates with the outer tissue-contacting surface and the at least one pocket extender to define a contoured frame configured to reduce friction against tissue as the staple cartridge is moved relative to tissue.
