A fastener cartridge comprising a cartridge body comprising a tissue-supporting deck, a longitudinal slot, cavities, and ridges protruding from the tissue-supporting deck is disclosed. The fastener cartridge further comprises fasteners positioned in the cavities, drivers supporting the fasteners, and a sled configured to engage the drivers to fire the fasteners from the cavities during a firing stroke. The sled comprises a central portion and ramps. The ramps comprise a first ramp on a first side of the central portion, a second ramp on the first side of the central portion, a third ramp on a second side of the central portion, and a fourth ramp on the second side of the central portion. The first ramp, the second ramp, and the third ramp are longitudinally-staggered. The central portion comprises a hump intermediate the first ramp and the third ramp, and a stabilizer extending from the hump distally beyond the ramps.

A surgical instrument (1) with a safety mechanism includes an end effector, an intermediate connector, and a controller (100), wherein the controller (100) includes housings (101, 102), a drive mechanism, the safety mechanism, and a reset mechanism, the drive mechanism, the safety mechanism and the reset mechanism being arranged or partially arranged in the housings (101, 102); the safety mechanism includes a safety trigger (104), a dry firing function block (109), and a biasing member (110). The surgical instrument can solve the problem that the instrument cannot be fired and reset when an automatic reset mechanism thereof fails, thereby protecting patient safety, and having a simple structure and a low cost.

A computer-assisted system comprises a manipulator configured to support a tool, a lockable joint, and a controller. The manipulator extends distally from a base and comprises a distal portion. The lockable joint is coupled to the base and located proximally relative to the base. The controller is operably coupled to a powered joint. The powered joint is located distally relative to the base. The controller is configured to perform operations. The operations comprise: driving the powered joint to move the distal portion while the lockable joint is locked, and driving the powered joint to move the base while the lockable joint is unlocked and a position of the distal portion is externally maintained. A method includes processes for operating a computer-assisted system. A method includes determining a desired motion envelope for a tool supported by a manipulator, and positioning a base of the manipulator based on the desired motion envelope.

Exemplary embodiments of a tissue repair device to repair tissue by deploying implants, comprising: a selector knob is configured to allow a user to change from a default position to a first position, position is indicated by a window positioned on a handle; a depth control knob is configured to adjust an exposure length of a needle under a depth control sheath to an appropriate or desired length to deploy a first implant and a second implant to secure with a tissue, a deployment knob is configured to push a pusher rod to deploy first implant from needle for delivering of a flexible member to secure tissue, deployment knob is configured to automatically spring back to a pre-specified position after deploying first implant from needle, deployment knob configured to push pusher rod to deploy second implant from needle for delivering of flexible member to secure tissue.

A device for safely approaching vertebral disc space utilizing stereotactic guidance, clearing material from the disc space, a device for expanding the disc space, stereotactic methods for implant planning and monitoring articulating instrument end effectors and a device for implantation into the disc space for the purpose of fusion or disc replacement.

A device for removing mucus from a nostril or earwax from an ear canal is disclosed herein. The device includes a light assembly, the light assembly including a light emitting device, the light emitting device configured to emit light so as to illuminate at least a portion of a nostril or an ear canal; and an extraction portion configured to be coupled to the light assembly, the extraction portion including an extraction element and a stop located adjacent to the extraction element, the extraction element sized and configured to fit within the nostril or the ear canal for extracting mucus or earwax, and the stop sized to prevent insertion of the stop into the nostril or the ear canal and limit the depth that the extraction element is able to be inserted into the nostril or the ear canal.

A tool adapter, consisting of an adapter arm having a proximal end terminating with a connection and a distal end having a circular coupling, the circular coupling having a center and defining an axis orthogonal to the circular coupling and passing through the center. The adapter also has a tool grip rotatingly connected to the circular coupling so as to permit rotation of the tool grip about the axis, the tool grip being configured to fixedly retain a tool along the axis.

A guiding device can include a guide including a through hole for insertion of an ultrasound probe that forms a tunnel to a bone. The guide can be configured to guide movement of the ultrasound probe inserted through the through hole; an offset portion offset from an axis of the through hole. The guiding device can also include an offset portion with an abutment portion configured to abut to an outer wall of the bone, on a side on which the through hole is located, in a direction orthogonal to the axis and a bone-tunnel introduction portion provided on an opposite side to the side on which the through hole is located and being configured to be inserted into the tunnel. The bone-tunnel introduction portion can have a sectional polygon shape smaller than a polygon on an inner circumferential face of the through hole.

A surgical instrument includes an end effector, a handle assembly, a knife drive assembly, and a lockout assembly. The end effector includes a pair of jaws, a knife, and an RF electrode. The handle assembly includes a housing associated with the first jaw, and an arm associated with the second jaw. The arm is pivotably coupled with the housing and pivots the second jaw between the open position and the closed position. The knife drive assembly includes a trigger slidably coupled with the housing, an actuating assembly, and a return assembly. The actuation assembly converts proximal translation of the trigger into distal actuation of the knife. The return assembly automatically actuates the knife from the fired position to the pre-fired position in response to the trigger reaching a predetermined proximal position. The lockout assembly prevents activation of the electrode and distal actuation of the knife while in the locked configuration.
