A surgical effector, a surgical tool, and a surgical robot are provided. The surgical effector includes a support part, a head part, a drive part, and a sealing member. The support part includes an inner cavity, the head part is at least partially movably arranged at a distal end of the support part, the drive part is slidably arranged in the inner cavity of the support part and is connected to a proximal end of the head part, the sealing member is connected to the drive part in a sealed manner at a first end thereof and is connected to the support part in a sealed manner at a second end thereof, and at least a part of the sealing member is deformable.

A surgical instrument comprising a surgical end effector that comprises a first jaw and a second jaw that is movably supported relative to the first jaw for selective movement between an open position and closed positions. The surgical instrument further comprises a closure member that is axially movable in response to closing and opening motions. The closure member comprises at least one opening cam that protrudes therefrom to movably engage a corresponding cam surface on the second jaw such that upon application of the opening motion, the at least one opening cam movably engages the corresponding cam surface to move the second jaw to an open position, even when the jaws are under a load.

An end effector for use by a surgeon to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. Each of the anvil and the cartridge has a face that is positionable on the anatomical structure. The anvil is coupled to the cartridge at first and second ends. The anvil is movable relative to the cartridge to define a first gap between the faces at the first ends that is different from a second gap between the faces at the second ends.

An apparatus includes a shaft assembly and an end effector. The shaft assembly includes a first tube, a second tube, and a distally projecting tongue. The second tube is coaxially disposed within the first tube. One of the first tube or the second tube is configured to translate relative to the other of the first tube or the second tube. The tongue is fixed to either the first tube or the second tube. The end effector includes an ultrasonic blade and a clamp arm. The clamp arm is pivotally coupled to the tongue. The clamp arm is configured to pivot toward and away from the ultrasonic blade in response to relative translation between the first and second tubes. The tongue is configured to flex relative to the first tube and the second tube in response to the clamp arm grasping tissue.

A rotatable jaw device for use with an endoscope and method of using a rotatable jaw device. The device includes a fork, and two jaws pivotally mounted to the fork. The jaws are movable between a predetermined closed position and a predetermined open position. At least one jaw has at least one protrusion on a surface of the jaw. The at least one protrusion prohibits movement of the two jaws in the opening direction beyond the predetermined open position. One jaw may have an elongated center void defined by twin jaw extensions, and the other jaw may rotate within the elongated center void when the two jaws move toward the predetermined closed position.

An end effector for stapling and cutting an anatomical structure includes an anvil, a cartridge, and a blade. The anvil has an anvil face and a plurality of staple pockets positioned on the anvil face. The cartridge has a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples. Each of the plurality of staples comprises a first staple leg, a second staple leg, and a crown connecting the first and second staple legs and having a midpoint. Each of the plurality of staples comprises an open staple configuration and a closed staple configuration where a first portion of the first staple leg and a second portion of the second staple leg are bent relative to the crown such that the first portion of the first staple leg and the second portion of the second staple leg cross the midpoint of the crown.

An end effector for a surgical clip applier includes a housing, jaws that include opposed first and second jaw members, each comprising an independent structure movable relative to the other, the first jaw member defining a first inner surface and the second jaw member defining a second inner surface opposite the first inner surface, and an actuation mechanism arranged within the housing and operable to move the jaws between open and closed positions. The actuation mechanism includes an actuation plate longitudinally movable within the housing, and a transition pin extending from the actuation plate and received within corresponding slots defined in each jaw member. Linear movement of the actuation plate drives the transition pin through the corresponding slots and thereby moves the jaws between the open and closed positions.

Provided is a bending structure and a joint function part, capable of ensuring sufficient flexibility and rigidity in an axial direction. The bending structure is provided with an outer coiled part formed of a wire wound in a coiled shape and an inner coiled part formed of a wire wound in a coiled shape and arranged in the outer coiled part, wherein the outer coiled part has a plurality of gaps to distance adjacent coils, and coils of the inner coiled part are provided so as to correspond to the gaps of the outer coiled part and fit between the adjacent coils while being in contact with the adjacent coils of the outer coiled part.

A surgical device comprising a first jaw member, a second jaw member, a clamping member and a clamp apparatus is disclosed. The clamping member is slidably positioned to translate at least partially through the first jaw member. The clamping member engages the first jaw member and the second jaw member, and has a knife blade for cutting tissue. A flange of the clamping member is configured to engage a cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position. The clamp apparatus is movable from a retracted position to an advanced position for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance. The clamping member and the clamp apparatus are separately movable.

A surgical apparatus for application of surgical clips to body tissue is provided. The surgical apparatus includes a housing, a drive assembly, a trigger, and a shaft assembly. The trigger is operatively connected with the drive assembly. The drive assembly is at least partially positioned within the housing. The shaft assembly extends distally from the housing and has a first tubular member pivotally connected with a second tubular member located distally from the first tubular member. An articulation mechanism is operatively connected between the first and second tubular members, and includes a gear rack, at least one gear, and a gear segment, respectfully connected with each other to pivot the second tubular member about the pivot axis. The gear rack and at least one gear are located within the first tubular member. The gear segment extends proximally from the second tubular member.
