Radiolucent grasping device

A device to be used by an operator which may grasp objects in a sterile or non-sterile field, and may facilitate the precise placement and passage of a needle or pin into tissues while using X-ray guidance. The device provides a secure hold while keeping the hands remote from the radiation field, and by permitting non-obstructed viewing of the held instrument and tissues. A radiolucent hammer may be used to help drive a needle into firm tissues without obscuring visualization.

Staple cartridge comprising a variable thickness compressible portion

A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.

Surgical clamp

Surgical devices and related methods are disclosed. An example end effector for a surgical device may include a first jaw, a second jaw, and an articulating mechanism operable to move the first jaw between an open position, an intermediate position, and a closed position. An example articulating mechanism may include a first jaw mount coupled to the first jaw so that movement of the first jaw mount along a path causes rotation and translation of the first jaw mount and the first jaw. A pivotably mounted crank may operably couple an actuator linkage to the first jaw mount so that moving the actuator linkage rotates the crank, and rotation of the crank may move the first jaw mount along the path.

Laparoscopic suturing instrument with perpendicular eccentric needle motion

A suture needle driving instrument comprises a shaft and an end effector. The end effector is located at the distal end of the shaft and includes a pair of needle grasping arms. Each grasping arm extends along a respective arm axis. The grasping arms are operable to drive a suture needle along a rotational path about an axis, such as one of the arm axes, that is offset from the central longitudinal axis of the shaft. The rotational path may be perpendicular to the axis of the shaft. A needle driven by the end effector may have an arc radius that is greater than the radius of the shaft. At least one of the needle grasping arms may include a dogleg feature positioning a distal portion of the grasping arm outside the radius of the shaft. The instrument may be used through a trocar during minimally invasive surgery.

ENDOSCOPIC REPOSABLE SURGICAL CLIP APPLIER
20170340325 · 2017-11-30 ·

The present disclosure relates to endoscopic reposable surgical clip appliers having a shaft assembly. The shaft assembly includes a spindle, pusher bar, and a barrel assembly. The spindle and pusher bar are each translatably supported within the shaft assembly. The barrel cam assembly includes a first portion in mechanical communication with the spindle and a second portion in mechanical communication with the pusher bar. Translation of the spindle effectuates rotation of a portion of the barrel cam assembly and the rotation of the portion of the barrel cam assembly effectuates translation of the pusher bar.

Surgical forceps
11253280 · 2022-02-22 · ·

A forceps includes an end effector assembly having first and second jaw members disposed in parallel orientation relative to one another. One or both of the jaw members is movable along a first axis relative to the other jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween. The first and second jaw members are configured to maintain the parallel orientation therebetween upon movement of the jaw members between the spaced-apart and approximated positions. A drive bar is coupled to one or both of the jaw members. The drive bar is selectively movable along a second axis that is different from the first axis between first and second positions for moving the jaw members between the spaced-apart and approximated positions.

Laparoscopic forceps assembly

A laparoscopic forceps comprising a handpiece including a distal end portion; a tubular member protruding from the distal end portion of the handpiece, the tubular member having a distal end, a pair of jaws having legs that are disposed within the tubular member and partially protruding from the distal end of the tubular member, the pair of jaws and the tubular member being movable relative to each other in a direction parallel to a longitudinal axis of the tubular member; wherein each of the pair of jaws has an arcuate section, and the pair of jaws are closable by advancing the tubular member over the arcuate section of the jaws; and an operable mechanism for creating relative motion between the pair of jaws and the tubular member along a direction parallel to the axis of the tubular member, wherein at the distal end portion of the tubular member there is a profile shape that is non-circular.

Articulatable motor powered surgical instruments with dedicated articulation motor arrangements

A surgical instrument that includes a housing that defines a longitudinal axis. An elongated shaft assembly is operably coupled to the housing by a shaft rotator assembly for selective rotation about the longitudinal axis relative to the housing. A first motor is supported by the housing and configured to selectively apply first rotary actuation motions to a first drive shaft that is operably supported by the housing and operably interfaces with a first shaft actuator. A second motor is supported by the shaft rotator assembly such that the second motor is rotatable about the longitudinal axis and is configured to apply second rotary actuation motions to a second shaft actuator.

Surgical clamp

A surgical clamp including a pair of jaws, which may be used to ablate or create lesions in tissue. In an exemplary embodiment, the jaws are movable between an articulated position in which the jaws are separated and not parallel to one another, an opened position in which the jaws are separated and substantially parallel to one another, and a closed position in which the jaws are adjacent and substantially parallel to one another.

FORCE TRANSMISSION MECHANISM FOR SURGICAL INSTRUMENT, AND RELATED SYSTEMS AND METHODS

A force transmission mechanism for a surgical instrument includes a worm drive, a lever arm, and an actuation element. The lever arm may include a follower member at a first end of the lever arm. The follower member engages the worm drive and is configured to be driven by the worm drive. The actuation element is connected the lever arm. The actuation element is configured to transmit force to actuate an end effector of the surgical instrument. Rotational movement of the worm drive imparts translational movement to the actuation element via the lever arm.
