The holder 112 and the rotary knob 9 are integrally coupled with each other, and are positioned respectively in a radial direction about the longitudinal axis Ax1 with respect to the handle 6. One of the holder 112 and the rotary knob 9 is positioned in a direction along the longitudinal axis Ax1 with respect to the handle 6.

An instrument may comprise a shaft and an end effector comprising a jaw mechanism coupled to the shaft. The jaw mechanism may comprise a first jaw member and a second jaw member movable relative to one another by pivoting about a pivot axis between an open configuration of the jaw mechanism and a closed configuration of the jaw mechanism. The second jaw member may be rotatable about a roll axis of the second jaw member between at least two orientations, the roll axis of the second jaw member being transverse to the pivot axis. In a first orientation of the at least two orientations, the jaw mechanism is configured to perform a first function. In a second orientation of the at least two orientations, the jaw mechanism is configured to perform a second function differing from the first function.

A surgical device comprises an elongate shaft (12) which extends from a proximal end region to a distal end region thereof, the shaft (12) defining a first lumen (14) for receiving an elongate camera device therein, a second lumen (16) for receiving a tissue manipulation device therein, and a third lumen (18) for receiving a tissue retrieval device therein, the first, second and third lumens (14, 16, 18) extending from the proximal end region to the distal end region of the elongate shaft, and having respective open ends at the distal end region of the elongate shaft. The surgical device further comprises an elongate camera device which extends along the first lumen, a tissue manipulation device which extends along the second lumen, and a tissue retrieval device which extends along the third lumen.

Systems, methods, and devices to facilitate insertion of certain leads with electrode(s) into patients are described. Leads can be implanted to work in conjunction with a cardiac pacemaker or cardiac defibrillator. A lead for cardiac therapy may be inserted into an intercostal space associated with the cardiac notch of a patient. Devices for delivery may include, for example, a delivery system coupled with an electrical lead and having a handle, a component advancer and insertion tips. The handle is configured to be actuated by an operator and the component advancer is configured to advance an electrical lead into the patient. The insertion tips can be configured to close around the electrical lead within the component advancer, to push through biological tissue, and to open to enable the lead to advance into the patient. The electrical lead can also be maintained in a particular orientation during the advancement into the patient.

A surgical system includes a housing, an ultrasonic transducer supported by the housing, an end effector assembly distally-spaced from the housing, a clamp lever, and a sensor. The end effector assembly includes an ultrasonic blade operably coupled to the ultrasonic transducer for receiving ultrasonic energy produced by the ultrasonic transducer, and a jaw member pivotable relative to the blade from an open position towards a clamping position for clamping tissue between the jaw member and the blade and imparting a clamping force to the clamped tissue. The clamp lever is operably coupled to the housing and the jaw member such that actuation of the clamp lever relative to the housing pivots the jaw member towards the blade. The sensor is configured to sense whether the clamp lever is sufficiently actuated so as to impart the clamping force to the clamped tissue.

An apparatus for sealing a puncture through tissue having an introducer sheath therein includes an elongate positioning member including a housing on a proximal end and an expandable member on a distal end, and a cartridge advanceable along the positioning member from a proximal position to a distal position. The cartridge includes a tubular member including a sealant and an advancer member disposed within lumen of the tubular member. A sleeve is slidably disposed over the tubular member distal end such that, when the tubular member is advanced over the positioning member, the tubular member distal end enters the introducer sheath while the sleeve is stopped and slides over the tubular member to expose the tubular member distal end within the introducer sheath. The introducer sheath and cartridge are then withdrawn, exposing the sealant within the puncture.

A medical system may include an insertion device having a handle, a shaft coupled to the handle of the insertion device, and a port positioned on the handle of the insertion device. The port may be in fluid communication with a working channel of the shaft. The port may be a female luer port. The medical system may further include a medical device having a control member terminating in an end effector, a handle having a plurality of circumferential slots along the length of the handle, and a plunger moveable along a longitudinal axis of the handle of the medical device between a first position and a second position. In the first position, the end effector may be positioned within the shaft, and in the second position, the end effector may be positioned distally of the shaft.

A surgical system comprises a handpiece and a battery. The handpiece includes a body, a handpiece controller, and a handpiece connector with a first coupler, a handpiece voltage terminal, and a handpiece data terminal. The battery has a housing, a cell, a battery controller, and a battery connector with a second coupler to rotatably engage the first coupler, a battery voltage terminal, and a battery data terminal. The second coupler receives the first coupler at an initial radial position and permits rotation to a first secured radial position and a second secured radial position. Rotation from the initial radial position to the first secured radial position engages the voltage terminals to transmit power between the cell and the handpiece controller, and rotation to the second secured radial position engages the data terminals to communicate data between the controllers while maintaining engagement between the voltage terminals.

A surgical occluding device includes a body portion configured to radially surround a tissue lumen. The body portion includes a plurality of segments and a plurality of folds. Each fold of the plurality of folds is defined between adjacent segments of the plurality of segments. Half of the folds of the plurality of folds define acute angles, and half of the folds of the plurality of folds define obtuse angles. The body portion is movable from a first orientation where the acute angle defines a first acute angle, to a second orientation where the acute angle defines a second, smaller acute angle.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.
