Surgical system pump and method therefor
First Claim
1. A method of automatically controlling a pump and supplying pressurized fluid via an output line to a fluid control valving system and to a surgical site, said pump adapted to be coupled to a fluid source and adapted to be disposed at an elevated position with respect to said fluid control valving system, the method comprising the steps of:
- providing a battery powered motor mechanically coupled to said pump;
monitoring fluid flow at or near the pump'"'"'s output and turning ON said motor and pumping fluid based upon fluid flow above a predetermined amount in said output line coupled thereto, said predetermined amount being greater than a system minimal flow; and
, permitting fluid flow at or below said system minimal flow without turning ON said motor and pump.

Abstract
The automatically controlled pump supplies pressurized irrigation fluid to a surgical site. The pump system includes a motor in a housing and a pump in a housing defining input and output ports. The pump has a rotatable impeller. The motor is powered by batteries. The system operates in conjunction with a downstream manual suction/irrigation control valve. In one system, an ON/OFF motor switch is controlled by fluid flow above a nominal flow by a sensor typically mounted downstream of the pump. In another, flow is detected by a negative buoyancy poppet having a “leaky” valve seat. When the poppet moves, its position is sensed and the switched motor is ON. In a remote control system, the motor is remotely controlled by a switch integrated into the manual control valve. One method automatically controls a pump by monitoring fluid flow above a system minimal flow and turning ON/OFF the motor based upon flow above the minimum.
