A surgical stapling system for stapling the tissue of a patient is disclosed. The stapling system comprises a housing, a shaft extending from the housing, and an end effector extending from the shaft. The end effector comprises a plurality of staples removably stored therein and, also, an anvil configured to deform the staples. The stapling system further comprises a firing mechanism configured to deploy the staples along a staple firing path longer than 60 mm, a camera configured to capture an image of the patient tissue, a display, and a controller configured to generate an image of the staple firing path, wherein the images are displayed on the display.

A surgical instrument comprising a surgical end effector that comprises a first jaw and a second jaw that is movably supported relative to the first jaw for selective movement between an open position and closed positions. The surgical instrument further comprises a closure member that is axially movable in response to closing and opening motions. The closure member comprises at least one opening cam that protrudes therefrom to movably engage a corresponding cam surface on the second jaw such that upon application of the opening motion, the at least one opening cam movably engages the corresponding cam surface to move the second jaw to an open position, even when the jaws are under a load.

Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, a driver, and an elongate drive wire. The elongate drive wire may be disconnected from the driver, first and second jaws, and the housing, which are left in vivo engaged with the tissue.

A surgical instrument includes a housing, a shaft extending from the housing, an end effector assembly extending from the shaft and configured to rotate and/or articulate relative to the housing, a motor disposed within the housing and operably coupled to the end effector assembly to rotate and/or articulate of the end effector assembly relative to the housing, and a sensing assembly configured to sense movement of the housing relative to a reference position and to drive the motor to rotate and/or articulate of the end effector assembly relative to the housing based upon the sensed movement. The sensing assembly is configured to operate in each of a standard mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in a similar direction, and a reversed mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in an opposite direction.

An apparatus includes a shaft assembly and an end effector. The shaft assembly includes a first tube, a second tube, and a distally projecting tongue. The second tube is coaxially disposed within the first tube. One of the first tube or the second tube is configured to translate relative to the other of the first tube or the second tube. The tongue is fixed to either the first tube or the second tube. The end effector includes an ultrasonic blade and a clamp arm. The clamp arm is pivotally coupled to the tongue. The clamp arm is configured to pivot toward and away from the ultrasonic blade in response to relative translation between the first and second tubes. The tongue is configured to flex relative to the first tube and the second tube in response to the clamp arm grasping tissue.

A surgical instrument includes a housing, an energizable member, and a deployment mechanism. The energizable member is movable relative to the housing between a storage position and a deployed position. The deployment mechanism includes a first actuator member movable relative to the housing from a first un-actuated position to a first actuated position to move the energizable member from the storage position to the deployed position and a second actuator member movable relative to the housing from a second un-actuated position to a second actuated position to move the energizable member from the deployed position to the storage position. Movement of the first actuator member from the first un-actuated position to the first actuated position effects movement of the second actuator member from the second actuated position to the second un-actuated position and vice versa.

A robotic surgical tool is disclosed. The robotic surgical tool can comprise an end effector comprising a firing member; a drive system responsive to a motor-driven input; and a proximal housing comprising a retraction mechanism. The retraction mechanism can comprise a control responsive to a manual input. The control can be rotatable in a first direction through a retraction motion and rotatable in a second direction through a reset motion. The retraction mechanism can further comprise a clutch coupled to the control. The clutch can be configured to drivingly engage the drive system as the control rotates through the retraction motion to supply a proximal retraction stroke to a firing bar and drivingly disengaged from the drive system as the control rotates through the reset motion to prevent any displacement of the firing bar by the retraction mechanism until the control is reset for a subsequent retraction motion.

A surgical cutting and stapling end effector. Various embodiments comprise a channel that is configured to operably support a removable staple cartridge. A rotary end effector drive shaft is supported within the channel and is configured to move a firing assembly longitudinally within the end effector to cause the sled to eject surgical staples from the staple cartridge. The firing assembly is prevented from moving distally through the channel unless a surgical staple cartridge that has a sled in a starting position has been seated within the channel.

A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.

A surgical stapling instrument is disclosed. An end effector for the surgical stapling instrument comprises a staple cartridge assembly and an anvil. The staple cartridge assembly comprises a proximal end, a distal end, and a cartridge body comprising a shortened nose at the distal end. The staple cartridge assembly further comprises staples removably stored in the cartridge body, a driver configured to support at least one of the staples, and a sled movable toward the distal end. The sled comprises a ramp configured to lift the driver and at least one of the staples and a base, wherein the shortened nose of the cartridge body is shorter than the base of the sled. The anvil comprises a staple forming surface comprising a plurality of staple forming pockets and a blunt distal nose extending downward toward the staple cartridge assembly.
