Treatment instrument with movable handle and fixed handle includes biasing member for biasing the movable handle in an opening direction and an assist system with attraction force, e.g., magnetic force, to attract the movable handle in a closing direction toward the fixed handle. Range of movement of movable handle includes first movable range and second movable range. The second movable range occurs when a second gripping piece, e.g. a jaw, is in contact with respect to a first gripping piece, e.g., a vibration transmission member, and the movable handle is then further moved in a direction toward the fixed handle to a fully closed position. In the second movable range, attraction forces associated with the assist system are smaller than biasing force from the biasing member so that, upon release of a gripping force by an operator, the movable handle moves away from the fixed handle.

An articulating ultrasonic surgical end effector for use with a hand-held surgical instrument or a robotic surgical system includes an articulation assembly, a clevis operably coupled to the articulation assembly, and a transducer assembly pivotably coupled to the clevis. The transducer assembly includes a transducer housing and an ultrasonic transducer and a waveguide disposed within the transducer housing. The waveguide is coupled to the ultrasonic transducer and extends distally from the ultrasonic transducer. The transducer assembly also includes an ultrasonic blade disposed at the distal end of the waveguide and extending from the transducer housing and a clamp arm pivotably coupled to the transducer housing and movable relative to the ultrasonic blade between an open position and a clamping position. Ultrasonic energy produced by the ultrasonic transducer is transmitted along the waveguide to the ultrasonic blade for treating tissue.

Provided is a surgical dissector instrument including a pair of arms pivotably connected intermediate their ends, with each arm having a handle at one end, and a tooth formation at the other, wherein the tooth formations are mutually opposable and asymmetrical in profile.

An ultrasonic blade is provided along a convexly arcuate distal edge and at least one longitudinal edge with a continuous array of teeth including a first subset of teeth along the convexly arcuate distal edge and a second subset of teeth along the at least one straight longitudinal edge. The teeth along the convexly arcuate distal edge differ in tooth length and optionally in inter-tooth separation or pitch from the teeth along one or both of the longitudinal edges.

An ultrasound treatment tool includes a handle 6, a vibration transmitting member 13 that is formed in an elongated shape, the vibration transmitting member being configured to transmit an ultrasound vibration generated by a vibration generation source, a holder 112 configured to hold the vibration transmitting portion 13, and a rotary knob 9 configured to rotate about a longitudinal axis Ax1 of the vibration transmitting portion 13 in accordance with a user operation. 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.

A catheter for debulking of an undesired deposit from an inner surface of at least one of a blood vessel wall and a stent located in a blood vessel, the catheter having a tip section comprising: circumferentially-directed laser optics; and a circular-action cutter, wherein said circumferentially-directed laser optics is configured to transmit laser radiation for modifying an area of the undesired deposit thereby preparing said area for penetration of said cutter, wherein said cutter is configured to cut through said modified area and thereby debulk at least a part of the undesired deposit. In addition, a catheter for pacemaker and ICD (Implantable Cardioverter Defibrillator) lead extraction is disclosed.

A method of displaying an operational parameter of a surgical system is disclosed. The method includes receiving, by a cloud computing system of the surgical system, first usage data, from a first subset of surgical hubs of the surgical system; receiving, by the cloud computing system, second usage data, from a second subset of surgical hubs of the surgical system; analyzing, by the cloud computing system, the first and the second usage data to correlate the first and the second usage data with surgical outcome data; determining, by the cloud computing system, based on the correlation, a recommended medical resource usage configuration; and displaying, on respective displays on the first and the second subset of surgical hubs, indications of the recommended medical resource usage configuration.

An electrosurgical probe for ablating tissue includes an elongated shaft having an axis and a distal end. An electrically insulating housing at the distal end of the shaft has a window, and an interior channel in the shaft extends through the housing to the window. The window faces laterally relative to the axis, and a moveable member with a blade-like electrode edge is disposed within the window. A motor drives the energized electrode edge axially in the window to ablate tissue.

A surgical instrument includes a shaft defining an axis, an end effector coupled to a distal portion thereof, a fixed handle coupled to a proximal portion thereof, a drive bar, a movable handle, and a linkage. The drive bar is disposed within the shaft and operably coupled to the end effector. The movable handle is movable relative to the fixed handle between open and closed positions and is coupled to the drive bar via a first pin on the axis. The linkage includes a first end portion coupled to the movable handle via a second pin and a second end portion coupled to the shaft via a third pin on the axis. In the closed position of the movable handle, the second pin is disposed in a near-over-center position relative to the axis to reduce a force necessary to maintain the movable handle in the closed position.
