A surgical system including a surgical instrument, a surgical visualization system, a display, and a feedback controller are presented. The feedback controller is in signal communication with the surgical instrument and the surgical visualization system. The feedback controller is configured to display, on the display, during an operation, live images derived from the surgical visualization system in a first layer and a status of the surgical instrument in a second layer. The status is configured to locate itself in said second layer in relation to a depiction of a feature of the surgical instrument and/or a feature of tissue in the first layer. The surgical instrument can include a surgical stapler, a knife, a robotic surgical instrument, combination thereof, or variation thereof.

Described here are systems, devices, and methods for providing remote manipulation or traction to tissue using one or more graspers, delivery devices, and magnetic control assemblies. The graspers may be configured for insertion into the patient during a minimally-invasive procedure, such as a laparoscopic operation. The graspers may be configured to releasably connect to tissue. In some embodiments, the grasper may comprise a clip, a clamp, a suction device, a coil, or the like, and may be configured to connect to any suitable tissue. Delivery devices may be configured to releasably engage a grasper to deliver the grasper, remove it from the patient, or reposition it. The delivery devices may additionally be configured to actuate the grasper to attach it to tissue and/or detach it from tissue. The magnetic control elements may be configured to be positioned externally of the body to move, reposition, and/or hold the grasper.

A powered surgical stapler comprising an outer housing body, a shaft housing rotatable relative to the outer housing body, an elongate shaft extending from the shaft housing and including a driver, an inner housing assembly configured to be removably attached to the outer housing body, a plurality of securing features, and a loading unit is disclosed. The inner housing assembly comprises a motor configured to output rotary motions, a battery, control electronics in signal communication with the motor and a shaft output configured to be driven by the motor. The plurality of securing features are configured to align and hold the inner housing assembly in a position which allows the shaft output to be operably attached to the driver. The loading unit is removably attachable to the elongate shaft and comprises an end effector configured to perform an end effector function in response to the rotary motions of the motor.

A surgical instrument including a channel that is configured to support a replaceable surgical staple cartridge therein. An anvil is movably supported on the channel and is configured to selectively move between an open position and a closed position. A rotary driven closure system operably interfaces with the anvil and is configured to move the anvil between the open position and the closed position upon application of rotary opening and closing motions thereto. The instrument also includes a rotary driven firing drive shaft and an axially movable firing member that is in driving engagement with the rotary driven firing drive shaft and is configured for sliding engagement with the channel and the anvil upon application of rotary firing motions to the rotary driven firing drive shaft.

A surgical instrument comprising a surgical end effector that defines a central end effector plane. The end effector includes a first jaw and a second jaw that is configured to mate with the first jaw along the end effector plane. The second jaw is pivotally coupled to the first jaw for pivotal travel about a pivot axis that is transverse to the end effector plane between an open position and a closed position. A closure assembly is operably coupled to the second jaw at first and second attachment points. The first attachment point is located a first lateral distance from the central end effector plane and the second attachment point is located a second lateral distance from the central end effector plane. The closure assembly is configured to generate axial and pivotal control motions in response to rotary closure motions applied thereto.

A surgical instrument includes a shaft, an end effector extending distally from the shaft, and a housing extending proximally from the shaft. The housing includes a motor configured to generate at least one motion to effectuate the end effector, and a power source configured to supply power to the surgical instrument, wherein the power source includes a casing, a data storage unit, and a deactivation mechanism configured to interrupt access to data stored in the data storage unit. In addition, the power source includes a battery pack and a deactivation mechanism configured to deactivate the battery pack if the casing is breached.

A surgical instrument with a parallel gripping and clamping vascular clamp, which is equipped with coupling elements which makes possible a combination of a known detachable operating arrangement and of an actuating tool, in order to keep the access opening in the thorax free of intrusive instruments. With the parallel gripping and clamping operating means of the inventive vascular clamp, the known scissor-like means are dispensed with, and a parallel adjustment of the operating means takes place by means of a lever gear according to the invention. The lever gear is formed from a stationary lever, constructed as a body element, and from several movable levers, consisting of the tension- and pressure element, a push-pull rod, two toggle levers, two pivot arms and two movable branches. The lever gear has nine axes and converts a linear drive movement for adjusting the operating means into a rotationally movable one, whereby the two movable branches are displaceable substantially in a parallel manner towards one another and away from one another.

A system and method for evaluating an operational capacity of a powered surgical system is disclosed. A sensor is configured to monitor an operational condition of the powered surgical system. A control circuit is configured to receive the operational condition of the powered surgical system from the sensor, store the received operational condition of the powered surgical system in the memory, evaluate the operational capacity of the powered surgical system based on the stored operational condition of the powered surgical system, and disable the powered surgical system in response to the evaluation of the operational capacity of the powered surgical system.

A powered stapling device has a motor which can be operated at differing speeds based on a parameter indicative of the assembly's capabilities. The powered stapling device has a control system for controlling the motor. The control system has the ability to pause or stop the advancement of the firing system. The control system can stop advancement of the motor when a force or torque exceeds a predetermined force of torque on the firing rod. The control system can recouple the motor so that the motor is able to continue advancement when the force falls below the predetermine force limit, or a different predetermined force limit.

A medical treatment tool includes an elongated insertion section; a grasper supported by a distal end of the insertion section so as to be openable and closable; a generator disposed at a proximal end of the insertion section and generating a force to drive the grasper; a transmitter transmitting the force generated by the generator to the distal end of the insertion section; an amplifier amplifying the force transmitted through the transmitter; and a toggle amplifying and converting the force amplified by the amplifier into a force directed to open or close the grasper.
