Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the insulative surface. A second jaw member of the end effector assembly includes an ultrasonic blade body positioned to oppose the insulative surface of the first jaw member, and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the ultrasonic blade body and positioned to oppose the first and second electrically-conductive surfaces, respectively, of the first jaw member. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween. The first and second electrically-conductive surfaces of the second jaw member are movable, independent of the first jaw member, relative to the first jaw member and the ultrasonic blade body between a retracted position and an extended position.

An effector includes a tubular body having a proximal end and a distal end. The effector holds a plug or closure at the distal end of the tubular body; an active electrode at the distal end of the body; an insulator on the body; and one or more return electrodes on the insulator. The body dissipates heat generated by the one or more return electrodes from the distal end of the body to the proximal end of the body.

An electrosurgical instrument (10) with two branches (11, 12) that are pivotably supported at each other by means of a pivot joint (13) is disclosed. The pivot joint (13) has a support pin (34) and a support cavity (37). The support pin (34) is particularly torque-proof connected with one of the branches (11) or (12) and rotatably supported in the support cavity (37) of the respective other branch (12) or (11). Between the branches (11, 12) a seal (45) is provided that sealingly abuts at the two branches (11, 12) and that surrounds the support pin (34) completely in the circumferential direction. Preferably, the support pin (34) is sealingly connected with the respective branch (11, 12) at its axial ends. In doing so, entering of contaminants in the area between the support pin (34) and the support cavity (37) from all sides or access possibilities is inhibited.

An electrosurgical instrument with first and second branches that are pivotably supported by a support pin is disclosed. The first branch has a first tissue contact surface and the second branch has a second tissue contact surface. The two tissue contact surfaces are electrically connected with an electric connection device at the first branch. The electric connection is at least partly established via a respective conductor. The second conductor is integrally formed by one single body. The second conductor has a contact section with at least one contact part in contact with an electrically conductive circumferential surface of the support pin, such that an electric rotation connection is established between the contact section and the support pin. In this manner the second conductor arranged in the first branch can establish an electric connection with the second branch via the support pin and further with the second tissue contact surface.

An electrosurgical instrument includes mutually movable instrument legs each comprising one or more electrode faces between which tissue can be clamped and treated in electrothermal manner. The movement of the instrument legs relative to each other can be delimited by at least two spacers which are spaced from each other in the longitudinal direction of the instrument legs and act on the instrument legs. At least one electrode face portion subjected to deflection in a closed position of the instrument legs is formed to be bow-shaped, in particular concave, the curvature being contrary to the bending direction to be expected.

A medical power supply includes a medical instrument and a guide tube. The power receiving member is arranged radially outside the insertion portion, and when the insertion portion is inserted into the guide tube to a predetermined length such that the power transmitting member and the power receiving member are close to each other, a power transmitting side proximal end surface of the power transmitting member and a power receiving side distal end surface of the power receiving member face each other in an axial direction of the insertion portion and are in a positional relationship such that wireless power supply is possible.

Surgical tool are disclosed that include a first tip and a second tip. The first tip and the second tip can have a first configuration, an intermediate configuration, and a second configuration. In the first configuration the tool operates as forceps and in the second configuration the tool operates as scissors. In the intermediate configuration the tool operates as a probe. The tips can be brought together to transition between the first configuration and the intermediate configuration. The tips can be rotated to transition between the intermediate configuration and the second configuration. Method are disclosed that include the step of providing a tool having a first tip extending distally and a second tip extending distally, moving at least one of the first tip and the second tip toward the other of the first tip and the second tip, and rotating the first tip and the second tip.

A robotic system can include a surgical instrument with a wrist including an elongate shaft extending between a proximal end and a distal end, a wrist extending from the distal end of the elongate shaft, and an end effector extending from the wrist. The end effector may include a first jaw and a second jaw, the first and second jaw being moveable between an open position in which ends of the jaws are separated from each other, and a closed position in which the ends of the jaws are closer to each other as compared to the open position. The surgical instrument may also include at least one rotary cutter extending from the wrist and positioned at least partially within a recess formed in a face of the first jaw.

Tissue treatment systems include an actuator handle assembly coupled with a clamp assembly having a first jaw mechanism and a second jaw mechanism. A first jaw mechanism includes a first flexible boot, a first flexible ablation member coupled with the first flexible boot, and a first rotatable jawbone disposed within the first flexible boot. A second jaw mechanism comprises a second flexible boot, a second flexible ablation member coupled with the second flexible boot, and a second rotatable jawbone disposed within the second flexible boot.
