Surgical irrigation apparatus and methods for use
First Claim
1. An irrigation system for use in surgery, said system comprising:
- a pump housing having a pump therein for pumping irrigation fluid to a patient;
a passage connected to said pump housing for conducting the irrigation fluid from said pump;
a hand piece connected to said passage, said hand piece having a mechanism for initiating a flow of the irrigation fluid from said pump to said hand piece;
a motor housing having a variable speed motor therein for operating said pump, said motor housing being operatively connected to said pump housing;
a power supply for energizing said motor;
a controller operatively connected to said motor and said power supply for regulating power to said motor; and
a pressure transducer housed within at least one of said pump housing and said motor housing, said pressure transducer being operatively connected to said controller for providing pressure data for use in regulating the power supplied to said motor.

Abstract
A surgical irrigation apparatus includes a disposable assembly and a reusable assembly. The disposable assembly includes an irrigation fluid pump and a hand piece having a supply passage for delivery of irrigation fluid to the surgical site. The reusable assembly includes a motor, a power source, and a pressure detector. The pressure detector assists in changing the power being supplied to the motor. The power is transferred from the motor to the pump with a magnetic coupler or other suitable device. The reusable assembly may alternatively include a sound receiver for picking up voice commands or other sounds to change the power being supplied to the motor. The reusable assembly may also alternatively include a controller that is operatively connected to a switch on the hand piece to permit a user to manually change the power being supplied to the motor. Related methods for surgical irrigation are also described.
