A surgical device for clipping tissue is disclosed. The surgical device comprises a housing comprising an electric motor, a shaft defining a central shaft axis, a clip magazine, and a clip crimping system. The clip magazine comprises a plurality of clips removably stored therein. The clip crimping system comprises a first jaw, a second jaw, and a distal portion comprising a clip receiving chamber defined between said first jaw and said second jaw. The distal portion is offset from said central shaft axis. The clip crimping system further comprises a proximal connection portion connecting said first jaw and said second jaw. The proximal connection portion is positioned along said central shaft axis. The clip crimping system further comprises a clamp operably coupled with said electric motor. The clamp is movable distally by said electric motor to perform a crimping stroke and engage said first jaw and said second jaw.

A gearbox assembly and surgical instrument including the same. The gearbox assembly includes a drive gear including a round gear and a lead screw such that a rotational input to the round gear rotates the lead screw. A first hub is threadingly engaged about the lead screw such that rotation of the lead screw translates the first hub. A second hub is spaced-apart from the first hub and engaged with a drive rod. A compression spring is disposed between the hubs. When a force acting against the drive rod is below a threshold, the rotational input translates the first hub, compression spring, second hub, and drive rod. When the force is equal to or above the threshold, the rotational input translates the first hub and compresses the compression spring against the second hub to maintain the second hub and drive rod in position.

An end effector assembly of a surgical system includes a blade and a jaw member movable relative to the blade between a spaced-apart position and an approximated position for clamping tissue. The blade defines a first width and the jaw member defines a second width wider than the first width. The jaw member defines a first side facing the blade and a second side facing away from the blade. A marking is formed on the second side of the jaw member facing away from the blade. The marking defines a third width substantially equal to the first width of the blade to allow a surgeon to visualize a width of the blade when the blade is not visible.

A cervical cup includes a body having a flange and a vacuum port so that application of a vacuum to the port will secure the cervical cup to a cervix disposed inside of the body of the cup. Example of the disclosed methodology to treat preterm birth includes inserting of a cervix into a cervical cup and applying a vacuum to a vacuum port of the cervical cup so as to secure the cervical cup to the cervix.

Retraction systems, assemblies, and devices for retracting an end unit are provided. A retraction assembly may be configured to move the end unit of a robot between a first state and a second state. A first signal may be received indicating a working condition. A first instruction may be generated to move the end unit from the second state to the first state. The retraction assembly may be caused to move the end unit from the second state to the first state based on receiving the first signal and the first instruction. The end unit may be held in the first state when the first signal is being received and the retraction assembly may move the end unit from the first state to the second state when the first signal is not received.

An ultrasonic surgical instrument includes a housing, a waveguide extending from the housing to a blade, a clamp jaw pivotable relative to the blade to clamp tissue, a drive member extending from the housing to the end effector and operably coupled to the clamp jaw such that translation of the drive member pivots the clamp jaw to exert a jaw force on the clamped tissue, a rigid slider operably coupled to the drive member such that translation of the rigid slider results in corresponding translation of the drive member, and a clamp lever. The clamp lever is actuatably coupled to the housing and operably coupled to the rigid slider such that a full actuation of the clamp lever translates the rigid slider and the drive member to thereby pivot the clamp jaw from the open position towards the clamping position with substantially no dampening of the jaw force.

A method of stapling tissue is disclosed. The method can include obtaining a staple cartridge including a plurality of staples, wherein each staple has a base and a leg extending from the base. The stapling method can also include firing the staples from the staple cartridge, wherein the staples are fired into tissue in a staple line. The staple line can include a first portion having a first flexibility and a second portion having a second flexibility, wherein the second flexibility is different than the first flexibility. A method of stapling tissue can also include adapting an anvil with an anvil plate having an arrangement of staple-forming pockets that differs from the staple-forming pockets in the anvil.

A surgical instrument comprised of a stapling end effector having a staple-applying assembly with opposing stapling surfaces defining a closure distance therebetween, wherein at least one stapling surface is movable, and a handle connected to the stapling end effector and comprising a staple-firing assembly that causes the staple-applying assembly to staple tissue between the stapling surfaces. The handle further comprises a power source, electric motor, and closure assembly that has a drive part movable by the motor, detection mechanism, a controller. The drive part is connected to the stapling end effector. When the motor is supplied with power, the drive part advances the movable stapling surface towards the opposing stapling surface. The detection mechanism detects a position of the drive part along the drive-part axis and the controller is configured to prevent stapling unless the drive part is at a position corresponding to a closure distance within a pre-defined range.

An axis-aligning, force-limiting periarticular/intraarticular reduction forceps suitable for the reduction and realignment of specific anatomic structures includes a pair of medial and lateral forceps tines. A pair of tine tips may terminate the forceps tines, respectively. A pair of lateral and medial forceps handles may extend from the medial and lateral forceps tines, respectively. A first tine/handle junction may attach the lateral forceps handle to the medial forceps tine. A second tine/handle junction may attach the medial forceps handle to the lateral forceps tine. The second tine/handle junction may be pivotally attached to the first tine/handle junction. A force quantifying and limiting mechanism limits the magnitude of clamping force the medial and lateral forceps handles apply to the medial and lateral forceps tines. A pair of X-ray-visible targets on the medial and lateral tines assist with axis alignment for the insertion of fixation devices.

A surgical system for use in a surgical theater is disclosed. The surgical system comprises a surgical tool and a surgical hub. The surgical tool comprises a motor, a motor controller in signal communication with the motor, and an end effector configured to perform an end effector function. The end effector is operably responsive to the motor. The surgical hub is in signal communication with the motor controller. The surgical hub is configured to detect a contextual cue within the surgical theater. The motor controller is configured to adjust an operating parameter of the motor based on the contextual cue detected by the surgical hub.
