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.

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.

Treatment instrument includes an operation button for receiving a user operation provided in a housing. The housing has a pair of first surfaces spaced apart at predetermined intervals and a sliding portion of the operation button, provided with a curved second surface having a predetermined curvature, is located in the space between the pair of first surfaces and configured for rotation and to press a switch element in response to a user operation to affect an associated treatment operation.

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.

Provided is a robotic system that includes 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.

A method for attaching a drive rod to a knife includes: forming a knife having proximal and distal ends; forming an aperture within the proximal end of the knife, the aperture including a series of fins disposed therein; weaving a distal end of a knife rod through the series of fins in an alternating manner; and engaging a cap onto the distal end of the knife drive rod to secure the knife drive rod within the aperture of the knife.

A surgical instrument includes a housing, a shaft extending from the housing, an end effector assembly extending from the shaft and configured to rotate and/or articulate relative to the housing, a motor disposed within the housing and operably coupled to the end effector assembly to rotate and/or articulate of the end effector assembly relative to the housing, and a sensing assembly configured to sense movement of the housing relative to a reference position and to drive the motor to rotate and/or articulate of the end effector assembly relative to the housing based upon the sensed movement. The sensing assembly is configured to operate in each of a standard mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in a similar direction, and a reversed mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in an opposite direction.

Various systems and methods for controlling the activation of energy surgical instruments are disclosed. An advance energy surgical instrument, such an electrosurgical instrument or an ultrasonic surgical instrument, can include one or more sensor assemblies for detecting the state or position of the end effector, arm, or other components of the surgical instrument. A control circuit can be configured to control the activation of the surgical instrument according to the state or position of the components of the surgical instrument.

An ultrasonic device may include an electromechanical ultrasonic system defined by a predetermined resonant frequency, in which the system may include an ultrasonic transducer coupled to an ultrasonic blade. A method of estimating a state of an end effector of the ultrasonic device may include applying a drive signal defined by a magnitude and a frequency to the ultrasonic transducer, sweeping the frequency of the drive signal from below a first resonance to above the first resonance of the electromagnetic ultrasonic system, measuring and recording, impedance/admittance circle variables R.sub.e, G.sub.e, X.sub.e, and B.sub.e, comparing, the measured impedance/admittance circle variables R.sub.e, G.sub.e, X.sub.e, and B.sub.e to reference impedance/admittance circle variables R.sub.ref, G.sub.ref, X.sub.ref, and B.sub.ref, and determining, a state or condition of the end effector based on the result of the comparison. An electromechanical ultrasonic system may include a control circuit to effect the method.
