An apparatus includes a body, a shaft assembly, an end effector, and a control module. The shaft assembly extends distally from the body and includes an acoustic waveguide. The waveguide is configured to acoustically couple with an ultrasonic transducer. The end effector includes an ultrasonic blade, a clamp arm, an electrode, and a sensor. The ultrasonic blade is in acoustic communication with the waveguide. The clamp arm is operable to compress tissue against the ultrasonic blade. The electrode is operable to apply radiofrequency (RF) electrosurgical energy to tissue. The sensor is operable to sense a condition of tissue contacted by the end effector. The control module is operable to control delivery of ultrasonic power and RF electrosurgical energy through the end effector based on data from the sensor.

A surgical instrument includes a housing having a shaft extending distally therefrom, an end effector assembly disposed at a distal end of the shaft, a handle assembly coupled to the housing for manipulating the end effector assembly, a deployable assembly, at least one actuator for deploying and retracting the deployable assembly, and a closure member. The closure member is keyed to the actuator(s) and operably positioned relative to the movable handle of the handle assembly such that, upon rotation of the actuator(s) relative to the housing from an un-actuated position to an actuated position, the closure member is urged into contact with the movable handle to urge the movable handle from an initial position to a compressed position, thereby moving the end effector assembly to an approximated position.

A device comprising: (a) a first working arm; (b) a body; (c) a shuttle, and (d) a bias device; wherein the bias device biases the first working arm relative to the body when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm relative to the body when the shuttle is in a second position.

An electrosurgical instrument includes a housing having a handle and an elongated shaft extending therefrom supporting an end effector assembly. The end effector assembly includes first and second jaw members each having a jaw housing and an electrically conductive tissue engaging surface. The first jaw member includes a U-shaped proximal flange that defines a cuff having sides configured to support a pivot and also that define cradles for securing a pivot bar. The second jaw member defines a U-shaped cuff for receiving the proximal flange the first jaw member. The cuff includes sides that define cradles for supporting the pivot thereon through the range of motion between first and second jaw members.

An improved drive shaft for controlling an end effector of surgical instrument having advantages over the prior art, specifically, the drive shaft includes two separate elongate elements, each including a flange at its proximal end for restricting the lateral movement of the drive shaft when installed within an outer shaft of the instrument. The dimensions of the flanges are such that they fit within the outer shaft with minimal clearance. This allows the drive shaft to be moved longitudinally within the outer shaft to actuate an end effector whilst minimizing any lateral movement. This consequently prevents the end effector from tilting as it is actuated. The drive members are arranged so that the flanges extend in opposite directions perpendicular to the length of the drive shaft. This helps to improve ease of assembly and provides space within the outer shaft for features such as connection wires and the like.

Methods of assembling a medical device including pivotably connecting a coupling link to a first lever. The coupling link including a main body and a tab extending away from the main body. The first lever having a first pivot and a boss. The method further including nesting the first lever and the coupling link with a second lever such that a recess in the second lever is supported by the boss, and such that an inner surface of the second lever is supported by the coupling link to provide a portion of the medical device in a sub-assembled state.

An energy treatment instrument includes a first grasping piece, and a second grasping piece which opens or closes relative to the first grasping piece and which grasps a blood vessel between the first grasping piece and the second grasping piece. In accordance with the kind of blood vessel grasped between the first grasping piece and the second grasping piece, an actuation state of the energy treatment instrument is switched between a first mode to coagulate a blood vessel of a circulatory system, and a second mode to coagulate a blood vessel of a pulmonary circulation in contrast to the first mode.

Provided is a system and medical device that includes self diagnosing control switches. The control switch may be slidable within a slot in order to control activation of some function of the medical device. Due to natural wear and tear of movement of a control switch, the distances along the sliding slot that correspond to how much energy is used for the function may need to be adjusted over time in order to reflect the changing physical attributes of the actuator mechanism. The self diagnosing control switches of the present disclosures may be configured to automatically adjust for these thresholds using, for example, Hall effect sensors and magnets. In addition, in some cases, the self diagnosing control switches may be capable of indicating external influences on the controls, as well as predict a time until replacement is needed.

A medical device may comprise an instrument comprising a shaft and a working end comprising a jaw mechanism, and a translating mechanism movable in a first direction and a second direction relative to the jaw mechanism, the first and second directions opposite to one another. The medical device may further comprise a controller configured to in response to a first input, control movement of the translating mechanism from a proximal position to an intermediate position relative to the jaw mechanism, in response to a second input, control movement of the translating mechanism from the intermediate position to a distal position relative to the jaw mechanism, control movement of the translating mechanism from the distal position back to the proximal position, and monitor a position of the translating mechanism to determine whether the translating mechanism has moved from the distal position back to the proximal position after a predetermined time period.

A surgical instrument is provided and includes a housing having a shaft. An end effector assembly operatively connects to the shaft and has a pair of first and second jaw members. A jaw insert is operably associated with the first and second jaw members. The jaw insert includes one or more cam slots defined therein configured to receive a cam pin that upon movement thereof rotates the first and second jaw members from an open position to a clamping position and an opening defined therein configured to securely house a pivot pin that provides a point of pivot for the first and second jaw members. The jaw insert is manufactured from an insulative medium to dielectrically isolate the first and second jaw members.
