A fluid flow controller includes a first body portion defining a receiving surface, a second body portion, and a fluid transfer device. The second body portion includes a controller engagement member, and is configured to couple to the first body portion such that the controller engagement member faces and is spaced from an engagement point of the receiving surface. The controller engagement member is configured to be adjusted from a first distance to a second distance closer to the engagement point than the first distance based on a force applied by a foot pedal apparatus. The fluid transfer device defines a flow channel configured to be adjusted from defining a first cross sectional area to a second, lesser cross sectional area while the controller engagement member is in contact with the first fluid transfer device and adjusted towards the second distance in response to the applied force.

Methods and apparatus for end effector control and calibration are described. The method may include detecting a signal in response to movement of a first tube relative to a second tube, the first tube driving movement of a clamp arm of the end effector. The method may further include determining a clamp arm position of the end effector relative to a ultrasonic blade of the end effector based on the signal. The method may also include adjusting a power output to the ultrasonic blade of the end effector based on the clamp arm position.

The disclosed apparatus, system and method may include at least a phacoemulsification surgical console having a customizable non-linear custom phacoemulsification mode. The apparatus, system and method may include an ultrasonic delivery tip; a foot pedal; and non-transitory computing code resident on a computing memory associated with a computing processor which, when executed by the processor, causes to be executed the steps of: receiving a percentage actuation of the foot pedal; calculating, including from a non-linear algorithm, a percentage actuation for the ultrasonic delivery tip corresponded to the received percentage foot pedal actuation; and dictating the calculated percentage actuation for the ultrasonic delivery tip actuation to the ultrasonic delivery tip.

An apparatus, system and method for providing a may include at least a phacoemulsification surgical console having a customizable non-linear custom aspiration mode. The console may include at least an aspirator; a foot pedal; and a non-transitory computing code resident on a computing memory associated with a computing processor which, when executed by the processor, causes to be executed the steps of: receiving a percentage actuation of the foot pedal; calculating, including from a non-linear algorithm, a percentage actuation for the aspirator corresponded to the received percentage foot pedal actuation; and dictating the calculated percentage aspirator actuation to the aspirator.

A dental device is disclosed comprising a dental handpiece, a controller including a microcontroller and a foot control pressure sensor, and a foot pedal. The foot pedal is in communication with the controller and controls the dental handpiece. The dental device is arranged to configure between at least two of a speed limiting mode, a feathering mode, and a standard mode. In the speed limiting mode, the controller proportions air flow so as to limit the speed of the dental handpiece to a specified speed. In the feathering mode, the foot pedal proportions air to the controller which then transmits the air to the dental handpiece such that the foot pedal controls the speed of the dental handpiece. In the standard mode, the speed of the dental handpiece is set without limiting by the controller and without feathering by the foot pedal.

A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. A delivery sleeve may be selectively provided that is configured to be disposed about the outer cannula for delivery of a variety of devices.

A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described, as well as alternative systems for tissue preservation and transport. The cutting device includes an outer cannula in which a reciprocating inner cannula is disposed. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A temperature control sleeve may be disposed around the tissue collector to control the temperature of the tissue samples. A preservation system may be supplied that is configured to deliver fluids to tissue samples in the tissue collector. A fluid supply sleeve may be disposed about the outer cannula and is selectively positionable along the length of the outer cannula.

The disclosed apparatus, system and method may include at least an adjustable platform for a surgical footpedal, such as may be associated with a phacoemulsification surgical console. The adjustable platform for a surgical footpedal may include a bearing arm having a mount; a pedal, having associated therewith one or more sensors indicative of at least one surgical setting; and a platform at a first end of the bearing arm distal from the mount, comprising a mating surface for receiving the pedal.
