A surgical instrument includes a shaft defining an axis, an end effector coupled to a distal portion thereof, a fixed handle coupled to a proximal portion thereof, a drive bar, a movable handle, and a linkage. The drive bar is disposed within the shaft and operably coupled to the end effector. The movable handle is movable relative to the fixed handle between open and closed positions and is coupled to the drive bar via a first pin on the axis. The linkage includes a first end portion coupled to the movable handle via a second pin and a second end portion coupled to the shaft via a third pin on the axis. In the closed position of the movable handle, the second pin is disposed in a near-over-center position relative to the axis to reduce a force necessary to maintain the movable handle in the closed position.

An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.

Surgical tools that can be used in single port laparoscopic procedures can include a low-profile handle assembly to minimize tool interference adjacent the incision site. For example, a handle assembly for a surgical instrument can have a generally in-line configuration extending linearly along a central longitudinal axis of an elongate shaft of the instrument. A linkage mechanism including a trigger, an actuation link, and an actuation shaft can be positioned within the in-line handle. The linkage mechanism can be pivoted between an open position in which end effectors of the instrument are open and a toggle position in which the end effectors are locked closed. A locking mechanism such as a ratchet mechanism can also be used to lock the end effectors. A surgical dissector can include gripping jaws having a curved profile or an angled elongate shaft to minimize tool interference and maximize visibility within a procedure site.

A surgical system comprising an electric motor and a surgical instrument is disclosed. The surgical instrument comprises a housing, a shaft extending from the housing, a fastener cartridge, an anvil, a translatable drive member, and a rotatable actuator knob. The housing comprises an input shaft operably coupled to the electric motor. The input shaft is rotatable in a first mode by the electric motor. The fastener cartridge comprises a plurality of fasteners removably stored therein. The anvil is configured to deform the fasteners. The translatable drive member is configured to move the anvil toward and away from the fastener cartridge. The translatable drive member is movable by the electric motor in the first mode. The rotatable actuator knob is configured to be rotated multiple full rotations in a second mode to manually cause the input shaft to move the anvil.

A clip cartridge assembly for use with a reposable surgical clip applier includes a clip tray, a plurality of surgical clips, and a cover. The clip tray includes a plurality of distally oriented, deflectable, resilient fingers projecting from a base wall thereof. Each resilient finger terminates in a distal shoulder and a proximal end of the clip tray is configured for selective connection with a clip pusher bar of an endoscopic assembly of the reposable surgical clip applier. The cover includes a plurality of distally oriented, deflectable, resilient fingers projecting within a channel defined through proximal and distal ends thereof. Each resilient finger of the cover terminates in a distal shoulder and the cover includes a pair of opposed slots defined within sidewalls of the channel configured to slidably retain the clip tray and the plurality of surgical clips therein. A reposable surgical clip applier is also provided.

An endoscope treatment tool includes: a forceps having a first forceps piece and a second forceps piece; and a joint. The second forceps piece includes a forceps cup, a first tooth, a second tooth, a third tooth, a fourth tooth. A length from a tip of the first tooth to a tip of the second tooth in a longitudinal direction defines a first length, a length from the tip of the first tooth to a tip of the third tooth in the longitudinal direction defines a second length, and the first length is shorter than the second length. A length from the tip of the first tooth to a tip of the fourth tooth in the longitudinal direction defines a third length and the second length is shorter than the third length.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

A trigger mechanism for a surgical instrument, particularly, a surgical stapling instrument provides significant mechanical advantages by increasing the length of the firing stroke of the surgical instrument while reducing the degree of movement of the trigger associated with the trigger mechanism. The trigger mechanism also reduces the forces required to actuate the trigger thereby enhancing usability and minimizing operator fatigue.
