A surgical tool includes a stage portion that includes opposing first and second ends, a lead screw and at least one spline that extend between the first and second ends, and a first layer of a carriage movably mounted to the lead screw and the at least one spline. An instrument portion is releasably coupled to the stage portion and includes one or more additional layers of the carriage removably coupled to the first layer, and an elongate shaft extending distally from the one or more additional layers and having an end effector arranged at a distal end of the elongate shaft. The elongate shaft and the end effector penetrate the elevator layer and the first end when the instrument portion is coupled to the stage portion.

A plurality of staples. A plurality of electrical contacts positioned at the proximal end of the cartridge body and electrically coupleable to the electrical connector upon the installation of the replaceable staple cartridge assembly in the end effector along a distal-to-proximal installation motion and electrically decoupleable from the electrical connector upon removal of the replaceable staple cartridge assembly from the end effector along a proximal-to-distal removal motion.

A surgical tool includes a handle having opposing first and second ends, a lead screw and a spline are rotatably coupled to and extend between the opposing ends. The spline is arranged a distance from the lead screw such that the lead screw assumes torsional loading generated by the spline. Another surgical tool includes first and second splines with a first activating mechanism coupled to the first spline and a second activating mechanism coupled to the second spline. Torsional loading generated by the first and second splines to operate the first and second activating mechanisms are balanced by rotating the first and second splines in opposite directions. A method of minimizing torsional loads on components of a robotic surgical tool includes actuating the surgical tool and assuming a torsional force acting on a carriage of the surgical tool with a load balancing member included in the surgical tool.

Drive patterns and spline arrangement for robotic surgical tools

A surgical system includes a detector, comprising an array of pixels configured to detect light reflected by a surgical instrument and generate a first signal comprising a first dataset representative of a visible image of the surgical instrument. The surgical system also includes a processor configured to receive the first signal, generate a modified image of the surgical instrument that includes a control panel. The control panel includes one or more control elements representative of one or more operating parameters of the surgical instrument. The processor is further configured to receive an input to the control panel from a user, the input being effective to change one of the operating parameters. The processor is also configured to generate a command signal based on the input to change the one of the operating parameters.

An end effector for use with a surgical stapling instrument is disclosed. The end effector comprises a first jaw, a second jaw movable relative to the first jaw to grasp tissue therebetween, and a staple cartridge. The staple cartridge comprises staples deployable into the tissue. The end effector further comprises a magnetic sensor configured to measure a parameter indicative of an identifying characteristic of the staple cartridge, an impedance sensor configured to measure a parameter indicative of an impedance of the tissue, and a processing unit in communication with the impedance sensor. The processing unit is configured to determine a property of the tissue based on an output of the impedance sensor.

Smart cartridge wake up operation and data retention

A robotic surgical tool includes a handle providing a drive input, an elongate shaft extendable through the handle and having an end effector arranged at a distal end of the shaft, and an accumulator system housed within the handle and operatively coupled to the drive input such that actuation of the drive input operates the accumulator system. At least one drive cable is threaded through the accumulator system and extends distally along the shaft, wherein operation of the accumulator system acts on the at least one drive cable to operate the end effector.

A surgical system includes a detector that includes an array of pixels configured to detect light reflected by a surgical device and generate a first signal. The first signal includes a first dataset representative of a visible image of the surgical device. The surgical system also includes a processor configured to receive the first signal and a second signal representative of one or more operating parameters of the surgical device. The processor is also configured to generate a modified image of the surgical device that includes information related to one or more operating parameters.

Surgical system with augmented reality display

A surgical stapler includes an anvil half and a cartridge half. The anvil half includes an anvil channel member and an anvil surface. The cartridge half releasably couples with the anvil half and includes a cartridge channel member having a distal portion that receives a staple cartridge, and a latching member coupled to the cartridge channel member and movable between open and closed positions. A resilient member is arranged at a proximal end of one of the anvil half or the cartridge half, and a projection is arranged at a proximal end of the other of the anvil half or the cartridge half. The resilient member is configured to contact and releasably couple with the projection to thereby couple the proximal end of the anvil half with the proximal end of the cartridge half while the latching member is in the open position.

Features to align and close linear surgical stapler

An ultrasonic surgical instrument includes an end effector including an ultrasonic blade, an ultrasonic waveguide, an ultrasonic transducer assembly, and a carrier. The acoustic waveguide includes at least a proximal portion thereof extending along a longitudinal axis. The ultrasonic transducer assembly includes a fixation member and is operatively connected to the acoustic waveguide such that the acoustic waveguide is in acoustic communication with an ultrasonic transducer.
