Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridges for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch movable in a lateral direction to either maintain the locking member in the disabled position or to allow the locking member to move into the locking position. The instrument may further include a stapler cartridge including an annular pin configured to be engaged by a drive member at a an axial position to create a detectable resistance for reload detection by a control unit to identify the type of stapler cartridge present in the surgical stapling instrument.

A tibial baseplate system is described. While the system can include any suitable component, in some instances, it includes tibial baseplate having a first and second surface, the second surface being substantially opposite to the first surface, which is configured to be seated on a resected surface at a proximal end of a tibia. In some cases, the baseplate also includes a first spacer coupling that is configured to couple a first spacer to at least one of a lateral side and a medial side of the baseplate such that the spacer is disposed between, and is configured to maintain a set minimal distance between, the proximal end of the tibia and a distal end of a femur when the tibial baseplate is seated on the resected surface at the proximal end of the tibia and the spacer is coupled to the tibial baseplate. Other implementations are discussed.

A surgical instrument system comprising a drive train and a control circuit is disclosed. The drive train comprises a motor and a shaft actuatable by the motor to actuate a function of an end effector. The control circuit is coupled to the motor, wherein the control circuit is configured to determine a relative excess capacity of the drive train, compare the relative excess capacity to a predetermined shifting threshold, and increase the speed of the motor based on the relative excess capacity exceeding the predetermined shifting threshold.

A staple cartridge assembly for use with a surgical stapler and surgical stapling systems are disclosed. The staple cartridge comprises a cartridge body comprising a proximal end. 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.

Break-away clutching includes a robotic system having a processor and a robotic structure with a plurality of joints, a plurality of linkages coupled by the plurality of joints, and a drive system or a brake system for facilitating or inhibiting motion of the robotic structure. The processor is configured to inhibit, using the drive system or brake system, manual articulation of the robotic structure in response to a first manual effort applied to the robotic structure being below an articulation threshold; facilitate, using the drive system or brake system, the manual articulation of the robotic structure in response to a second manual effort applied to the robotic structure exceeding the articulation threshold; and inhibit, using the drive system or brake system, further manual articulation of the robotic structure in response to a determination that a speed of the manual articulation of the robotic structure has fallen below a speed threshold.

A master manipulator arm capable of maintaining pose, a joint transmission structure of a manipulator arm, and a surgical robot are provided. In the master manipulator arm, multiple first linkage joints on a front linkage use a joint module to adjust the angle and displacement, multiple second linkage joints of a rear linkage use a transmission gear pair to perform angle and displacement transmission. The mounting structure of the rear linkage can be more compact. A doctor controls a master tool to transmit a surgical operation from the manipulator arm to a surgical instrument. An arm joint uses of the transmission gear pair to perform angle and displacement transmission.

A surgical robotic system includes a robotic arm having an instrument drive unit with at least one motor and an instrument coupled to the instrument drive unit and actuatable by the at least one motor. The instrument includes a first jaw member and a second jaw member, where at least one of the first or second jaw members is movable by the at least one motor relative to the other of the first or second jaw members from an open jaw position to a closed jaw position. The system also includes a surgeon console having a display configured to output a graphical user interface. The system further includes a processor configured to receive a first user input from the graphical user interface. The first user input selects a force mode from a plurality of force modes for the instrument. The plurality of force modes includes a first force mode and a second force mode, where in the first force mode the force applied by the instrument is higher than during the second force mode. The processor is further configured to set the instrument drive unit to the selected force mode.

A robotic surgical instrument includes a housing having a shaft extending therefrom configured to receive a first end effector including jaw members moveable between a fully open position wherein the jaw members are spaced a maximum distance relative to one another and a closed position wherein a closure pressure between the jaw members is within a predetermined range. A drive rod actuates the first end effector upon translation thereof. The housing includes a spring compression assembly having proximal and distal hubs with the compression spring disposed therebetween. A jaw drive input rotates a drive gear to translate the distal hub relative to the proximal hub to compress the compression spring and actuate the end effector. Once the jaw members are fully open, the jaw drive input rotates a preset number of degrees to compress the compression spring and approximate the jaw members to a closure pressure within the predetermined range.

An expandable trial can include an inferior portion, a superior portion, and a middle expanding portion as well as load cells for monitoring the load on the trial. The trial may also include recesses on its lateral sides to provide spacing to accommodate a disc removal tool so tissue can be cleared monitoring load. In addition, neural foramen spacing can be monitoring to provide information about how much neural release has been achieved as the disc is cleaned and the spine is positioned and repositioned.

A method of operating a surgical instrument is disclosed. The surgical instrument includes an electronic system comprising an electric motor coupled to the end effector; a motor controller coupled to the motor; a parameter threshold detection module configured to monitor multiple parameter thresholds; a sensing module configured to sense tissue compression; a processor coupled to the parameter threshold detection module and the motor controller; and a memory coupled to the processor. The memory stores executable instructions that when executed by the processor cause the processor to monitor multiple levels of action thresholds and monitor speed of the motor and increment a drive unit of the motor, sense tissue compression, and provide rate and control feedback to the user of the surgical instrument.
