Various arrangements of fluidics systems are disclosed. In one arrangement, an aspiration circuit for a fluidics system is disclosed that selectively controls aspiration. The aspiration circuit comprises an aspiration line operatively connected to a surgical instrument, an aspiration exhaust line operatively connected to a waste receptacle; an aspiration vent line connected at a first end to the aspiration line; and a selectively variable vent valve operatively connected to the aspiration vent line. The variable vent valve may be selectively moved to vary aspiration pressure within the aspiration line. Other fluidics systems are disclosed that include a selectively positionable irrigation valve that may also be incorporated into a fluidics system that includes a variable vent valve.

Selectively moveable valve elements for aspiration and irrigation circuits

A surgical system comprises a pressurized irrigation fluid source; an irrigation line fluidly coupled to the pressurized irrigation fluid source; a hand piece fluidly coupled to the irrigation line; and a controller for controlling the pressurized irrigation fluid source. The controller controls the pressurized irrigation fluid source based on an estimated flow value modified by a compensation factor.

Pressure control in phacoemulsification system

A surgical system comprises a pressurized irrigation fluid source; an irrigation line fluidly coupled to the pressurized irrigation fluid source; a hand piece fluidly coupled to the irrigation line; an irrigation pressure sensor located at or along the pressurized irrigation fluid source or irrigation line; and a controller for controlling the pressurized irrigation fluid source. The controller controls the pressurized irrigation fluid source based on a reading from the irrigation pressure sensor and an estimated flow value modified by a compensation factor.

A stationary exercise cycle. The stationary exercise cycle includes a frame, a crank rotatably connected to the frame, a driven wheel rotatably connected to the frame, and a frame stiffener. The frame includes a down tube and a fork. The crank and the driven wheel are in operative communication via a continuous flexible member. The frame stiffener is connected to the down tube and the fork and encircled by the continuous flexible member.

Apparatus, system, and method for cycle improvements

A surgical system comprises a pressurized irrigation fluid source; an aspiration pressure sensor associated with an aspiration line; and a controller for controlling the pressurized irrigation fluid source. The controller controls the pressurized irrigation fluid source based on a reading from the aspiration pressure sensor and an estimated flow value modified by a compensation factor.

A cycle with tapered drivetrain connections. The cycle includes a frame, a crank rotatably connected to the frame, and a driven wheel rotatably connected to the frame. The crank includes a crank arm and a crank spindle rotatably connected to the frame and non-rotatably connected to the crank arm. The crank spindle includes a crank mating surface to interface with the crank arm. The diameter of the crank spindle continuously decreases along at least a portion of the crank mating surface in a lateral direction. The crank arm includes a crank bore to interface with the crank mating surface. At least a portion of the crank bore has a diameter that continuously decreases in lateral direction. At least a portion of the crank bore taper has a taper rate and diameter equal to a taper rate and diameter of at least a portion of the crank spindle taper.

A surgical system with a variable controller that allows the user to selectively vary the level of venting performance.

Surgical system

A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines an approximate temperature of the eye using an irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip.

A surf disc has a planar bottom surface and parallel top surface with an upwardly extending hemispherical dome. An annular thumb recess is formed in the top surface and a frusto-conical rocker is formed in the bottom surface.

Irrigation solution bag

An irrigation source identification system includes an irrigation source, an imaging device, and a processor. The irrigation source includes a container for holding a quantity of irrigation fluid and a port fluidly coupled to the container. The port has an outlet end and a neck. The neck has a plurality of protrusions selected from a grouping of protrusions. The plurality of protrusions provides a unique identifier for the container. An imaging device images the neck and the plurality of protrusions of the irrigation source, and the processor determines which identifier is associated with the image.
