An ultrasonic surgical instrument including an ultrasonically actuated blade or end effector having a treatment portion. The blade can define a central axis and at least one axis which is transverse to the central axis, wherein the transverse axis can lie within a plane which is perpendicular, or normal, to the longitudinal axis and can define a cross-section of the treatment portion. Such a cross-section can include a central portion and a step extending from the central portion, wherein the central portion can comprise a width, and wherein the step can comprise a cutting edge. In at least one embodiment, the cutting edge can be defined by first and second surfaces which define an angle therebetween. In various embodiments, the position of the cutting edge and/or the angle between the cutting edge surfaces can be selected in order to balance the blade with respect to the transverse axis.

Ultrasonic surgical instrument blades

In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

End effector coupling arrangements for a surgical cutting and stapling instrument

In some embodiments, a tube portion can be configured to be fluidically coupled to a patient access component. A source of pressurized fluid can be coupled to the tube portion and can be configured to deliver fluid to the tube portion at a source pressure. A fluid pressure regulating device can include an expandable reservoir and can be coupled to the tube portion such that the expandable reservoir is in fluidic communication with the tube portion. The fluid pressure regulating device can be configured such that, when fluid is delivered from the source of pressurized fluid to the lumen of the tube portion at the source pressure, the expandable reservoir of the fluid pressure regulating device can receive fluid such that the expandable reservoir of the fluid pressure regulating device expands and fluid is delivered from the lumen of the tube portion to the patient via the patient access component.

Systems, apparatus, and methods for reducing fluid pressure in a fluid line

A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.

Rapid fluid delivery system

In some embodiments, a system can include a fluid delivery assembly and a drive assembly. The fluid delivery assembly is configured to be releasably mechanically and, optionally, electrically coupled to the drive assembly. When the fluid delivery assembly is releasably coupled to the drive assembly, the drive assembly can control delivery of fluid from the fluid delivery assembly (e.g., to a patient). For example, the drive assembly can be releasably coupled to the fluid delivery assembly to control delivery of fluid from the fluid delivery assembly to provide continuous (e.g., non-pulsatile) fluid flow from the fluid delivery assembly.

Systems, apparatus, and methods for fluid infusion

A surgical instrument is disclosed including a transducer configured to provide vibrations along a longitudinal axis, an end effector operably coupled to the transducer, and a stationary lower jaw extending parallel to the end effector. The end effector extends along the longitudinal axis. The end effector comprises a blade. The stationary lower jaw comprises a clamp face positioned distal to the blade. The end effector is movable relative to the stationary lower jaw to drive the blade distally towards the clamp face. The end effector comprises a hollow lumen. The end effector further comprises at least one member extended across a portion of the hollow lumen.

Surgical instruments

In some embodiments, a housing can define a reservoir. A lower cap can be coupled to the housing and define an outlet, and an upper cap can be coupled to the housing and can define an inlet. The upper cap can include an extending portion extending laterally a distance beyond an outermost extending portion of the lower cap relative to a central axis of the housing such that, when the lower cap and the extending portion of the upper cap contact a horizontal surface, the central axis of the housing is transverse to the surface and a sealing member is configured to sealingly engage a sealing surface of a valve seat prior to a liquid fluid level within a reservoir decreasing below a minimum threshold fluid level.

Systems, apparatus, and methods for filtering air from a fluid line

A loading unit coupleable to a surgical stapling system is disclosed. The loading unit comprises an end effector, a firing system, and a shaft assembly extending proximally from the end effector. The end effector comprises a first jaw and a second jaw movable relative to the first jaw between an open position and a clamped position. The firing system comprises a firing assembly and an indicator. The firing assembly is movable toward a distal position through the end effector in response to a firing motion from the surgical stapling system. The indicator is configured to visually communicate a position of the firing assembly to a user of the surgical stapling system. The shaft assembly is removably couplable with the surgical stapling system and comprises an open slot region aligned with the firing assembly. The open slot region extends proximally with respect to the second jaw.

Loading unit coupleable to a surgical stapling system

An infusion device includes a housing with an interior chamber sized and configured to hold at least a flange and plunger of a syringe, a trigger held by the housing, and a lever in communication with the trigger and including an upwardly extending cam with a cam path having an upper end. The cam is in communication with the flange of the syringe. In response to actuation of the trigger to dispense fluid from the syringe, the upper end of the cam travels upward above the syringe and longitudinally toward a dispensing end of the syringe to linearly translate the plunger of the syringe in a first direction to dispense fluid from the syringe. To refill fluid into the syringe, the upper end of the cam travels downward and longitudinally away from the dispensing end of the syringe to linearly translate the plunger in a second direction to intake fluid.

Apparatus and kits for fluid infusion

A surgical instrument for use with a mechanized surgical system that includes a roll drive unit operable by a motor. The instrument includes an elongate shaft having a longitudinal axis, and an end effector and handle on the shaft. The handle includes an actuator manually operable by a user to mechanically actuate the end effector. The shaft includes a roll joint positioned between proximal and distal shaft portions, such that the distal shaft portion is longitudinally rotatable relative to the proximal shaft portion at the roll joint. The instrument further includes a drive segment on the distal shaft portion, the drive segment including first features rotationally engageable with second features of the roll drive unit such that operation of the motor causes the distal shaft portion to axially roll relative to the proximal shaft portion.

Instruments for mechanized surgical system

An ultrasonic surgical instrument is disclosed. The ultrasonic surgical instrument includes a housing, an ultrasonic transducer assembly to selectively generate ultrasonic motion, a motor within the housing, an outer sheath coupled to the housing, and a blade operably coupled to the ultrasonic transducer assembly and rotatably supported within the outer sheath for rotation with the ultrasonic transducer assembly. The ultrasonic transducer assembly is rotatably supported within the housing. The motor is configured to selectively apply a rotary motion to the ultrasonic transducer assembly. The outer sheath includes a distal tip portion defining a tip cavity. The blade includes a tissue-cutting distal end rotatably supported within the tip cavity. A portion of the tissue-cutting distal end is configured to apply the ultrasonic motion to tissue.

Rotatable cutting implements with friction reducing material for ultrasonic surgical instruments

In one general aspect, various embodiments are directed to systems and methods for controlling a surgical instrument. The surgical instrument may comprise an ultrasonic transducer, a blade extending distally from the ultrasonic transducer along a longitudinal axis, and a motor coupled to the ultrasonic transducer. The motor, when activated, may rotate the ultrasonic transducer and the blade about the longitudinal axis. A control system may receive an indication to operate the surgical instrument according to an ultrasonic-only mode. The control system may instruct the motor to rotate the blade to a park position, and activate the ultrasonic transducer to longitudinally vibrate the blade.

Control systems for ultrasonically powered surgical instruments

A method of balancing an ultrasonic instrument having an ultrasonically actuated blade is disclosed. The blade includes a body portion and a step portion extending from the body portion. The body portion comprises a first side, a second side, and a width defined between the first and second sides. The step portion includes a first surface, a second surface, and a cutting edge situated intermediate the first and second surfaces. The second surface extends between a first plane including the cutting edge and a second plane which is parallel to the first plane. The first and second surfaces are not parallel and are oriented such that there is an angle defined therebetween. The method comprises the steps of configuring at least a portion of the blade such that a relationship is substantially equal to zero.

A motorized surgical system includes at least one support positionable within a sterile field in proximity to a patient positioned on a surgical table. An instrument driver is carried by the support and includes a steerable distal end positionable in a body cavity. A user input device is carried by the support and is configured to generate movement signals in response to manual manipulation of a portion of the user input device by a user. One or more steering motors are operably coupled to the instrument driver and are operable to deflect the steerable distal end of the instrument driver in response to the movement signals.
