35 is activated in the on position all other switches are in the off position when sensor 19 is activated the signal emitted from sensor 19 is transmitted through cysto turp switch 35 which is closed contact point 35 a of cysto turp switch 35 enables the signal to pass directly to a point of activation for suction meanwhile the signal also passes through contact point 35 b of cysto turp switch 35 and proceeds to activate relay 28 which in turn disconnects relay 11 and the irrigation pump however after passing through relay 28 the signal is transmitted to and activates relay 24 which will open either solenoid valve 3 or 4 thereby allowing the fluid to bypass the pump and undergo a gravitational flow in this case the irrigation fluid will be sucked by the suction which will help the flow of the irrigation fluid that would otherwise be determined by gravity only this type of suction irrigation flow will be very safe for cysto turp procedures where fluid pressure is of the utmost importance in carrying out a successful procedure finally with reference to fig2 there is shown a connector 20 that will be used for connecting an automatic electrode retractor for suction irrigation with an electro surgery unit electrode attachment relay 21 will automatically retract the electrode when suction is activated with the suction irrigation device so that the electrode will not be in the way of the suction tip this retraction of the electrode is reversed and will further lock the exposed electrode in place when electro surgery is employed this automatic retraction.
