Embodiments are directed to a medical robot system including a robot coupled to an end-effectuator element with the robot configured to control movement and positioning of the end-effectuator in relation to the patient. One embodiment is a method for removing bone with a robot system comprising: taking a two-dimensional slice through a computed tomography scan volume of target anatomy; placing a perimeter on a pathway to the target anatomy; and controlling a drill assembly with the robot system to remove bone along the pathway in the intersection of the perimeter and the two-dimensional slice.

A device comprises a base. A support is attached to the base. The support is shaped to receive a calf of a person and adapted to receive a wire or pin for securing a tibia of a person. A foot plate is attachable to the base. The foot plate has a plurality of attached members. The members are configured for receiving at least a first wire or pin to fix a foot of the person relative to the foot plate while the foot plate is oriented normal to a superior-inferior direction of the foot. The foot plate is rotatable relative to the base while the foot plate is attached to the base.

In a method of forming a FinFET, a first sacrificial layer is formed over a source/drain structure of a FinFET structure and an isolation insulating layer. The first sacrificial layer is recessed so that a remaining layer of the first sacrificial layer is formed on the isolation insulating layer and an upper portion of the source/drain structure is exposed. A second sacrificial layer is formed on the remaining layer and the exposed source/drain structure. The second sacrificial layer and the remaining layer are patterned, thereby forming an opening. A dielectric layer is formed in the opening. After the dielectric layer is formed, the patterned first and second sacrificial layers are removed to form a contact opening over the source/drain structure. A conductive layer is formed in the contact opening.

An electrosurgical forceps includes first and second shafts configured to rotate about a pivot to move jaw members between an open position and a closed position. A knife deployment mechanism is operably coupled to a knife and is configured to move the knife between a retracted position and an extended position. A knife lockout is configured to move between a first position wherein the jaw members are in the open position and movement of the knife from the retracted position to the extended position is prevented, a second position wherein the jaw members are in the closed position and movement of the knife from the retracted position to the extended position is permitted, and a third position wherein the jaw members are in the closed position and movement of the knife from the retracted position to the extended position is prevented.

Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft including a reciprocating driveshaft disposed within the elongated shaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft for displacing one or more fasteners within the elongated shaft towards a distal fastener deployment position. In some embodiments, the surgical instrument may include a removable preload lock-out attached to the elongated shaft to prevent the follower from applying a preload to the fasteners.

A surgical stapling apparatus includes a loading unit having first and second jaw members, a drive beam, and a firing lockout assembly. The drive beam is axially movable within the loading unit during a firing sequence. The firing sequence includes an advancement stroke which moves the first and second jaw members to an approximated position and a retraction stroke which moves the first and second jaw members to an unapproximated position. The firing lockout assembly includes an iterating plate, a capture gear, and a lockout pin. The iterating plate is disposed adjacent to the drive beam and is incrementally movable proximally within the loading unit during the firing sequence. The capture gear is rotatable between first and second positions during the firing sequence and is configured to move the iterating plate. The lockout pin is configured to lock the drive beam after a pre-determined number of firing sequences.

A system for deploying an implant cut from a biological tissue into an eye of a patient including a delivery device and a nose cone assembly, a tubular shaft projecting from the distal end region of the nose cone and comprising a lumen. Related devices, systems, and methods are provided.

A harvesting assembly for harvesting a tissue graft from surrounding tissue is disclosed including a guide. The guide includes a means for fixedly engaging with an anterior surface of the tendon. The guide also includes a means of guiding a cutting blade along a preferred trajectory into and along a length of the tendon. The guide also includes a means of guiding a truncating blade along a preferred trajectory across a width of tendon. The cutting blade may include two parallel blades for forming lateral sides of the tendon graft simultaneously. Each of the two parallel blades may define a leading edge that extends along at least a 90 degree arc that is equidistant from a stop on the cutting blade. The stop in combination with the guide may limit a cut depth into the tendon for a range of cutting blade handle elevation angles.

Described herein are systems and apparatus of surgical instruments engineered for integration with robotic surgical systems to enhance precision in surgical procedures. Also described herein are methods of using such surgical instruments in performing surgical procedures. The use of such surgical instruments reduce complications arising from misalignment during surgery. The disclosed technology assists in stages of a surgical procedure that require a precise trajectory to be followed. Surgical instrument guides are attached to a universal surgical instrument guide, which is engineered to attach directly or indirectly with a robotic arm of a robotic surgical system. Surgical instruments can then be precisely guided along an axis defined by the universal surgical instrument guide. Individual instruments are easily inserted and removed from the channel of the universal surgical instrument guide, thus allowing a range of instruments to be used throughout a procedure while maintaining the surgical trajectory.

Apparatus and methods employing same for loading and inserting an inverting tube apparatus into a body lumen, such as a blood vessel, including introducers for inverting tube apparatuses. Also described herein are stacked tractor regions and methods of using them for removing larger and/or longer materials from the body lumen. Also described herein are methods and apparatuses for assisting in the manual operation the inverting tube apparatuses described herein, including grips.
