Disclosed is a surgical instrument with an end-effector adapted and configured to deliver a plurality of energy modalities to tissue at a distal end thereof. The energy modalities may be applied simultaneously, independently, or sequentially. A generator is electrically coupled to the surgical instrument and is configured to supply a plurality of energy modalities to the end-effector. In one aspect, the generator is configured to supply electrosurgical energy (e.g., monopolar or bipolar radio frequency (RF) energy) and ultrasonic energy to the end-effector to allow the end-effector to interact with the tissue. The energy modalities may be supplied to the end-effector by a single generator or multiple generators.

Method of operating a combination ultrasonic / bipolar RF surgical device with a combination energy modality end-effector

An end-effector is disclosed including an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator and a clamp arm including a clamp jaw and a cantilever electrode fixed to the clamp jaw. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. The clamp arm may include an I-beam shaped clamp arm pad and the cantilever electrode is disposed between the I-beam. The clamp jaw, the cantilever electrode, and the clamp arm pad may define recesses along a length coinciding with the ultrasonic blade. The clamp arm pad may be fixed to the clamp jaw and disposed between the clamp jaw and the cantilever electrode and may extend beyond the surface of the cantilever electrode. The clamp arm may include a stationary gap setting pad and movable floating gap setting pads.

Asymmetric segmented ultrasonic support pad for cooperative engagement with a movable RF electrode

An end-effector is disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw, a clamp arm pad, and a cantilever electrode that is free to deflect. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. Also disclosed are configurations where the clamp arm includes a peripheral cantilever electrode and a clamp arm pad extending beyond the electrode, a floating cantilever electrode and a resilient clamp arm pad, an interlocked cantilever electrode plate and a clamp arm pad configured to receive the plate, a laterally deflectable cantilever electrode and a clamp arm pad extending beyond the electrode, and a flexible cantilever electrode and a clamp arm pad extending beyond the electrode.

Deflectable support of RF energy electrode with respect to opposing ultrasonic blade

An ultrasonic surgical instrument includes a body, an ultrasonic supported by the body, a shaft extending distally from the body and defining a shaft axis, a waveguide extending distally through the shaft, and an end effector arranged at a distal end of the shaft. The end effector includes an ultrasonic blade coupled to a distal end of the waveguide and having a primary blade treatment surface configured to treat tissue, and a clamp arm coupled to the distal end of the shaft. The shaft and the waveguide are selectively rotatable relative to one another about the shaft axis through a predefined range of angular motion between an assembly state and an operational state. In the assembly state, the clamp arm and the primary blade treatment surface are rotationally offset from one another. In the operational state, the clamp arm and the primary blade treatment surface are rotationally aligned.

Ultrasonic surgical instrument with pre-assembled acoustic assembly

A bite block that is inserted into a patient's mouth during an endoscopic diagnostic or surgical procedure that has a channel for receiving an endoscope or other surgical instrument through the patient's mouth and additional channels transmitting a gas to the patient and transmitting expired gas from the patient.

Disclosed is an interface between a drug delivery cassette and a medical effector system. The cassette may be mounted to the medical effector system in such a way that a fluid tube located on the cassette is positioned adjacent to a pump located on the medical effector system. The medical effector system may purge the fluid line of air by activating the pump and forcing fluid through the fluid line until a sensor positioned to monitor the fluid line indicates that fluid and not air is present in the tube. To prevent air purging of the fluid tube when connected to the patient, the medical effector system prohibits air purging unless the drug delivery end portion of the fluid tube is in a designated storage site located on the cassette. This is accomplished with a position sensor at the storage site that monitors the position of the fluid tube.

Drug cassette

Disclosed is a drug-delivery cassette for use with a drug delivery device. The cassette includes a main board and a luer site base portion connected to the main board for positioning a luer on the main board. A drip chamber is included on the main board to collect any drug that exits the luer when the luer is attached to the luer site portion. A deflectable sensor beam is positioned to detect the presence or absence of a luer in the luer site base portion. The drug-delivery cassette further includes a drug vial spike attachable to and detachable from the cassette main board that is connected to the luer by way of a drug delivery tube.

Connector for oral nasal cannula

A linear surgical stapler having clamping and firing triggers pivotally mounted to the frame of the instrument for pivotal rotation toward a hand grip is disclosed. The clamping trigger is positioned between the firing trigger and the hand grip. Each of the triggers are pivotally mounted to pivot pins spaced from each other within the body portion of the frame. Pivotal rotation of the first trigger is independent of pivotal rotation of the second trigger. When the clamping trigger is pivotally rotated toward the hand grip, the clamping and firing transmission assemblies move distally in tandem. Before the first trigger is pivoted, the firing transmission assembly blocks pivotal rotation of the second trigger. When the first trigger is pivoted, the initial distal movement of the firing transmission assembly enables the firing trigger to be in a position to pivotally rotate, and therefore cause the firing of staples. Additionally, a feature enabling the retention of the clamping trigger in intermediate and fully clamped positions is disclosed, where upon release of the retention feature, the clamping trigger can return to its original position by overriding the intermediate position. Finally, although the invention is described with particular reference to a linear stapler containing clamping and firing triggers, it has broader applicability to any surgical instrument which has first and second triggers pivotally actuated to transmit work to an end effector for performing first and second surgical functions during a desired surgical procedure.

Trigger mechanism for surgical instruments

An endoscopic surgical instrument is disclosed which is particularly facilitated for grasping the anvil portion of an circular surgical stapling device. The present instrument includes a generally elongated shaft, with a pair of cooperating jaw members disposed at the distal end of the shaft. The jaw members cooperate in a pincer-like action for gripping the anvil portion of the associated surgical stapler therebetween. The jaw members include cooperating jaw portions, each of which defines a semi-cylindrical gripping surface. The jaw portions are angularly disposed relative to the longitudinal axis of the associated shaft, and are otherwise configured to facilitate gripping and manipulation of the anvil portion of the surgical stapling device, as well as tissue manipulation.
