An electrosurgical device having a first shaft with a tang positioned along an intermediate portion to provide a pivot point that is offset from the longitudinal axis. A second shaft is pivotally coupled to the tang of the first shaft using a slot that accepts the tang of the first shaft. The second shaft is formed from three portions, each of which extends along a different longitudinal axis so that the jaws of the device will be closed when the second shaft abuts a stop of the first shaft.

A surgical instrument comprising an end effector including a first jaw and a second jaw rotatable relative to the first jaw is disclosed. One or both of the first jaw and the second jaw comprise alignment features.

A bone screw insertion device, comprises an outer sleeve extending from a proximal end to a distal end and including a channel extending therethrough and a driving member extending longitudinally through the channel of the outer sleeve from a proximal end to a distal end configured to engage a driving recess of a bone screw, the outer sleeve movable relative to the driving member between a first position in which the distal end of the outer sleeve extends over and covers a proximal portion of a bone screw engaged with the driving member, to a second position in which the distal end of the outer sleeve is longitudinally aligned with a proximal end of a bone screw engaged with the driving member.

A device for applying rubber bands in the human body and in other living beings includes: an axial element having a first handle; a trigger movably mounted on the axial element having one or more handles for moving the trigger along the axial element wherein the trigger serves to pull a wire; and an assembly that has a spool for winding up the wire. The spool is tightly connected with the trigger by a gear mechanism formed in such a way that, when the trigger is pulled, the spool is not rotationally driven and the wire is pulled along by way of the pulling movement of the trigger, whereby one or more rubber bands can be applied to a part of a living being to be treated, and that when the trigger moves back into a starting position, the wire is wound onto the spool.

According to one embodiment of the present disclosure, a surgical robotic system includes a robotic arm having an instrument drive unit and a surgical instrument rotatable by the instrument drive unit about an instrument axis. The system also includes a surgical console including at least one handle controller having a handle rotatable about a handle axis and configured to receive a user input for moving the surgical instrument. The system further includes a controller configured to receive the user input and to instruct the robotic arm to flip the surgical instrument in response to the user input, wherein the user input is an angle of rotation of the handle about the handle axis that is less than an angle of rotation of the surgical instrument of about 180°.

Surgical instruments and their methods of use are described. In one embodiment, a surgical instrument includes a power transmission including a trigger and a fastener driver operatively coupled to the trigger. Actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position. Additionally, an actuation lockout system operatively associated with the power transmission is moveable between a locked configuration and an unlocked configuration. The actuation lockout system prevents movement of the fastener driver from the first position to the second position when the actuation lockout system is in the locked configuration. Actuation of the trigger from the first configuration towards the second configuration moves the actuation lockout system from the locked configuration to the unlocked configuration.

A hip/shoulder prosthesis includes: a head component; a metaphyseal component; a diaphyseal nail, and a locking device. The head component includes: a front face and rear face; with a bore, and first and second shaped recesses in the rear face. The metaphyseal component includes: a central transverse aperture at an angle to the metaphyseal component's axis; a first end configured for threaded engagement within the bore of the head component; and a longitudinal hole that begins at the second end, transects the transverse aperture and reaches the first end, to receive the locking device. The diaphyseal nail is inserted in the femoral or humeral canal, and includes: fastening apertures that receive corresponding screws for fastening the diaphyseal nail to the femur or humerus; a portion configured to be received within, and engage, the transverse aperture of the metaphyseal component, and a transverse hole configured to receive the locking device.

Electrical instrument for applying radiofrequency and/or microwave frequency energy to tissue, comprising: a distal part comprising an instrument tip for applying radiofrequency and/or microwave frequency energy to tissue, the instrument tip comprising first and second conductive elements; a coaxial feed cable comprising an inner conductor, a tubular outer conductor coaxial with the inner conductor, and dielectric material separating the inner and outer conductors, the coaxial feed cable being for conveying radiofrequency and/or microwave frequency energy to the distal part; wherein: the inner conductor is electrically connected to the first conductive element and the outer conductor is electrically connected to the second conductive element through a rotatable connection between the distal part and the coaxial feed cable that allows rotation of the distal part relative to the coaxial feed cable; and the instrument comprises an actuator for rotating the distal part in a first rotational direction relative to the feed cable.

A surgical instrument is provided having an actuator mechanism with an integrated extension element. The surgical instrument comprises a handle assembly, an elongate shaft, and an end effector. The end effector can comprise a jaw assembly having atraumatic pads positioned thereon to reduce force on grasped tissue. An actuator is movable within the elongate shaft to actuate jaws of the jaw assembly responsive to movement of a movable handle of the handle assembly. The actuator can have an integrated extension element that allows the actuator to translate within the elongate shaft upon application of a relatively low force and translate and extend upon application of a relatively higher force to the actuator to limit the force applied by the jaw assembly. The actuator is also able to utilize force stored with the integrated extension element to provide a dynamic amount of force used to grasp the tissue in scenarios where the tissue volume decreases while in the jaws.
