Abstract

A surgical smoke evacuator synchronizing system includes a smoke evacuator system; a smoke or debris generating surgical device having a power cord with a plug for connection to a power source; and a monitoring system including a first receptacle for receiving the plug of the power cord; a cable connected to the first receptacle having a number of lines and having a second plug for connection to a power source receptacle; a current sensing loop for receiving at least one line of the cable; a detector circuit for sensing the current level in the cable; and a control device, responsive to a level of current in the cable, representing that the surgical device is operating, for enabling the smoke evacuator system and responsive to a level of current in the cable representing that the surgical device has completed operating for disabling the smoke evacuator system.

Claims

1. A surgical smoke evacuator synchronizing system, comprising:

a smoke evacuator system;

a smoke or debris generating surgical device having a power cord with a plug for connection to a power source;

a monitoring system including a first receptacle for receiving said plug of said power cord;

a cable connected to said first receptacle and having a number of lines and having a second plug for connection to a power source receptacle;

a current sensing loop for receiving at least one line of said cable;

a detector circuit for sensing the current level in said cable; and

control means, responsive to a level of current in said cable, representing that said surgical device is operating, for enabling said smoke evacuator system and responsive to a level of current in said cable representing that said surgical device has completed operating for disabling said smoke evacuator system.

2. The surgical smoke evacuator synchronizing system of claim 1 in which said control means includes a control circuit in said monitoring system and an actuator circuit in said smoke evacuator system, said actuator circuit controls power to said smoke evacuator system and said control circuit operates said actuator circuit.

3. The surgical smoke evacuator synchronizing system of claim 1 in which said control means includes means for directly controlling the power to energize said smoke evacuator system.

4. The surgical smoke evacuator synchronizing system of claim 1 further including delay means for disabling said smoke evacuator system a predetermined time after said surgical device has completed operating.
