Abstract

Claims (11)

1. A method of operating a fastener applicator, the method comprising:

repositioning a first trigger of the fastener applicator with respect to a handle from a first position to a second position;

closing a jaw assembly coupled to the handle of the fastener applicator due to movement of the first trigger to the second position;

preventing repositioning of a second trigger between an initial position and an actuated position relative to the first trigger by an interlock coupled to the second trigger until the first trigger is moved to the second position, wherein the interlock includes a cam follower engaged with a cam channel, and wherein the handle includes the cam channel and the second trigger includes the cam follower;

repositioning the second trigger to the actuated position relative to the first trigger after the first trigger is moved to the second position; and

retracting one or more fastener supporting structures comprising at least one protrusion movably extendable and retractable with respect to at least one jaw of the jaw assembly of the fastener applicator due to repositioning of the second trigger to the actuated position.

2. The method of claim 1 wherein the fastener applicator comprises a second interlock coupled to the first trigger, the method further comprising preventing movement of the first trigger from the second position to the first position with the second interlock until the second trigger is moved to the actuated position relative to the first trigger, and repositioning the first trigger from the second position back to the first position after the second trigger is moved to the actuated position relative to the first trigger.

3. The method of claim 1 , wherein rotating the first trigger from the first position to the second position includes traversing the cam follower along a first leg of the channel.

4. The method of claim 3 , wherein the first leg is formed concentrically with respect to a pivot about which the first trigger rotates.

5. The method of claim 1 , wherein rotating the second trigger to the actuated position relative to the first trigger includes traversing the cam follower along a portion of the channel transverse to the first leg.

6. The method of claim 1 , wherein rotating the first trigger from the first position to the second position includes moving the second trigger in tandem with the first trigger.
