Abstract: Embodiments of the invention include drive units and other effective types of movement inducing devices that include load sensing mechanisms capable of giving feedback to a user when a force is being applied to the devices during use. The applied force for which monitoring is provided may be one or more of a lateral force transverse to a longitudinal rotating axis of a surgical blade, burr, or other mechanism, a force applied along the longitudinal rotating axis, and other forces.

Abstract: Featured is a closed loop surgical system including one or more control units that are configured to form a fluid control subsystem for fluid control and a device control subsystem for controlling a surgical device. The two control subsystems in combination provide an automatic self-managed closed loop system for the control of fluid into and out of the surgical site by means of intelligent communication and for maintaining a preselected pressure desired by the surgeon. In particular embodiments, this is accomplished by utilizing empirically correlated motor speed and load measurements, based on supplied current, from the surgical resection device when using its specific resection capability. For example, automatically adjusting fluid flow responsive to changes in loading of a surgical device or automatically sensing a load change for the surgical device during a surgical procedure and automatically changing (increasing or decreasing) fluid flow responsive to the load change.

Abstract: A surgical drive apparatus includes a rotating shaft of a sectioning device and a drive unit having a motor disposed in a motor chamber, in which the motor rotationally couples to the rotating shaft as the rotating shaft extends through an end of the motor chamber. A suction chamber is defined by an interior of a cap, in which the end of the motor chamber is receptive to the cap for sealing engagement with the drive unit, and a rotary tool such as the sectioning device extends through the cap for rotational movement relative to the cap while maintaining fluid communication with the suction chamber. For evacuation of surgical material, an outflow tube is in fluid communication with the suction chamber for providing a fluid path to the suctioning device via the suction chamber. The drive protrudes from the motor chamber which is sealed to allow cleaning and sterilization.

Abstract: A hand tool comprises: a handle, a cavity, and a drive adapter. The handle is disposed at a proximal end of the hand tool. The cavity is disposed at a distal end of the hand tool. The drive adapter is disposed in the cavity to rotate about an axis of the hand tool. In one embodiment, the drive adapter includes a hollowed volume extending through the drive adapter from a first opening at a tip of the drive adapter to a second opening (such as an a sidewall) of the drive adapter into the cavity. According to one configuration, the hollowed volume extends from the tip of the drive adapter to multiple openings disposed on a respective sidewall of the drive adapter. A respective sidewall of the drive adapter including one or more openings is free from contacting a circumferential surface in the hand tool defining the cavity.

Abstract: According to one configuration, a hand tool attachment assembly includes a cap, an outer tube, and an inner tube. The cap includes a hollowed volume to matably secure the cap to a distal end of a hand tool. The outer tube is affixed to the cap opposite the hollowed region. The inner tube is disposed in the outer tube and rotates with respect to the outer tube. A fastening resource disposed on an inner surface of the cap enables securedly attaching of the cap to the distal end of the hand tool.

Abstract: A fluid flow device includes a housing configured to releasably mate with a surgical control unit for controlling fluid flow during a surgical procedure. First and second ports measure fluid pressure within a fluid path provided within the housing. The fluid flow device includes a restrictor for restricting fluid flow at a restriction location along the fluid path. The first port is located upstream of the restriction location and the second port is located downstream of the restriction location. A fluid pump is provided within the housing.
