A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Surgical instrument with selectively actuated gap-setting features for end effector

The present application provides a dispensing nozzle assembly for mixing a first fluid and a second fluid. The dispensing nozzle assembly may include a target assembly with a number of fins and a number of channels and a static mixer positioned about the fins.

Dispensing nozzle assemblies with static mixers

An automatic injection device is provided, where the device includes a syringe carrier and a retraction assembly. The syringe carrier may include two identical parts that are discrete from one another and interlock with one another. Carrier includes a cushion to support the syringe. Protrusions may be provided on cushion to further support syringe. The retraction assembly includes a shuttle and a follower, the follower having a moveable latch. The follower has a coupled configuration in which the latch is biasedly coupled to the shuttle, and a decoupled configuration in which the latch is in sliding engagement with a curvilinear surface of the shuttle.

Medication injection system

A surgical instrument includes an ultrasonic waveguide extending through a body assembly. An ultrasonic blade connects to the ultrasonic waveguide. A clamp arm assembly of the surgical instrument is able to move from an opened position for receiving a tissue toward a closed position for clamping the tissue. The clamp arm assembly includes a clamp body and a clamp pad facing the ultrasonic blade. A clamp arm actuator of the surgical instrument is able to move from a first position toward a second position to direct the clamp arm assembly from the opened position toward the closed position. A modular coupling of the surgical instrument connects to the clamp pad such that at least the clamp pad can be disconnected relative to the ultrasonic blade for replacement thereof.

Surgical instrument with removable end effector components

An apparatus includes a body assembly, an acoustic waveguide, an ultrasonic blade, a liquid dispensing feature, and a control module. The liquid dispensing feature is positioned distally relative to the body assembly. The liquid dispensing feature is positioned adjacent to the ultrasonic blade. The liquid dispensing feature is configured to deliver a flow of cooling liquid to the ultrasonic blade. The control module is operable to regulate fluid flow through the liquid dispensing feature.

Features and methods to control delivery of cooling fluid to end effector of ultrasonic surgical instrument

An automatic injection device is provided, where the device includes a syringe carrier and a retraction assembly. The syringe carrier includes two identical parts that are discrete from one another and interlock with one another. The retraction assembly includes a shuttle and a follower, the follower having a moveable latch. The follower has a coupled configuration in which the latch is biasedly coupled to the shuttle, and a decoupled configuration in which the latch is in sliding engagement with a curvilinear surface of the shuttle.

Automatic injection system

The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.

Method of manufacturing a flexible circuit electrode for electrosurgical instrument

A surgical instrument has a first modular assembly and a second modular assembly. The first modular assembly has a body, an ultrasonic waveguide, an ultrasonic blade connected to a distal end of the ultrasonic waveguide, and a coupling member that movably couples with the body. The second modular assembly has a clamp arm assembly with a first pivot coupling, a clamp pad assembly with a second pivot coupling, and a distal outer sheath that selectively couples to the body of the first modular assembly via the coupling member. The distal outer sheath has an interior surface that houses a portion of the ultrasonic waveguide, and this interior surface also houses the first pivot coupling and the second pivot coupling.

Surgical instrument with removable clamp arm assembly

Various ultrasonic instruments are disclosed. The ultrasonic instruments include structures configured to indicate the cutting length of the instruments, detect when grasped tissue has extended beyond the cutting length of the instrument, and prevent tissue from extending beyond the cutting length. Several techniques for each types of structures are disclosed.

Tissue loading of a surgical instrument

Various ultrasonic instruments are disclosed. The ultrasonic instruments include an ultrasonic waveguide acoustically coupled to an ultrasonic transducer. Several techniques for acoustically coupling the ultrasonic transducer to the ultrasonic waveguide are disclosed.

Ultrasonic transducer to waveguide acoustic coupling, connections, and configurations

An ultrasonic surgical instrument includes a body, a shaft, an ultrasonic transducer, a waveguide, and an end effector coupled to a distal end of the shaft. A rotation knob is rotatably coupled to the body and is configured to rotate the shaft, the waveguide, and the end effector together relative to the body. A torque transfer structure is positioned radially outwardly of and in direct contact with the waveguide at an acoustic node thereof. The torque transfer structure is rotationally fixed relative to the waveguide and is configured to rotationally couple the waveguide with the shaft and the rotation knob. The waveguide includes a first axial constraining feature defining a distally facing surface, and the torque transfer structure includes a second axial constraining feature defining a proximally facing surface configured to abut the distally facing surface to constrain the waveguide axially relative to the torque transfer structure and the body.

Acoustic drivetrain with external collar at nodal position

Aspects of the present disclosure include various ultrasonic surgical instruments. At least one disclosed surgical instrument includes a waveguide including a blade and a transducer base plate. The transducer base plate may be coupled to the waveguide to define a tapered joint at an interface between the waveguide and the transducer base plate. The transducer base plate may include first and second sides defining corresponding first and second flat faces configured to receive first and second piezoelectric elements. The first and second piezoelectric elements are configured to operate in a D31 mode.
