Abstract
A control lever assembly adapted for use with a powered surgical instrument which prevents the instrument from being inadvertently or accidentally activated. The assembly 10 includes a depressible control lever 20 for controlling the action of the instrument and a second safety lever or latch 30 which engages the trigger pin 6 of instrument only when selectively positioned with respect to control lever 20. Control lever 20 is secured to cutting device 2 by a mounting bracket 12. Safety latch 30 is pivotally carried by control lever 20 for shiftable movement between a safety position and an operational position. In the operational position, safety latch 30 engages trigger pin 6 when control lever 20 is depressed. Safety latch 30 cannot be switched from its safety position to its operational position when control lever 20 is depressed; therefore, the instrument is 'locked-out' and cannot be inadvertently activated even when control lever 20 is depressed. Safety latch 30 can only be manually shifted from the safety position to the operational position when control lever 20 is released, which ensures safe handling of the instrument.
