Surgical system pump and method therefor
First Claim
1. An automatically controlled pump for supplying pressurized fluid via an output line to a surgical site, said pump adapted to be coupled to a fluid source via an input line, said pump comprising:
- a motor and a motor housing;
a pump disposed within a pump housing, said pump having a rotatably disposed impeller coupled to said motor, said pump housing defining a fluid input and a fluid output port respectively adapted to be coupled to said input and said output line;
said motor powered by at least one battery;
a switch, turning ON and OFF said motor and controlled by fluid pressure at or near said fluid output port; and
, said pump housing attached below said motor housing wherein said motor is powered by at least one battery mounted in a battery housing above said pump housing.

Abstract
The automatically controlled pump includes a battery-powered motor with a housing, a pump in a housing with input and output ports. A switch turns ON and OFF the motor due to fluid pressure at the output. Sometimes, the pump housing is below the motor housing and below the battery housing. The input port is beneath the impeller and the output port. A version also includes a manual ON and OFF switch actuated by an operator and a check valve limiting upstream flow of the pressurized fluid. The fluid pressure sensitive switch is mounted downstream of the check valve. An irrigation surgical kit includes the automatically controlled pump, a spike for a fluid source bag, fluid lines and an operator controlled valve unit disposed at or near the surgical site. The method monitors fluid pressure at or near the pump'"'"'s output and turns ON and OFF the motor.

8. A method of automatically controlling a pump and supplying pressurized fluid via an output line to a surgical site, said pump adapted to be coupled to a fluid source, the method comprising the steps of:
-
providing a battery powered motor mechanically coupled to said pump;
monitoring fluid pressure with respect to the pump'"'"'s output and turning ON and OFF said motor based upon fluid pressure above or below a predetermined value in said output line coupled thereto; and
supplying fluid from said fluid source beneath said pump'"'"'s output; and
supplying battery power to said motor above said pump'"'"'s output. - View Dependent Claims (9, 10, 11)
