Abstract
A surgical stapler can comprise: a housing having side walls an end wall, a front wall, and a upper side that define a channel; a trigger; and a thermoplastic leaf spring having a proximal end and a distal end, the leaf spring comprising a non-corrugated portion and a corrugated portion. The leaf spring is attached to the trigger at the proximal end. The leaf spring extends from the trigger, through the channel toward the upper side. In an embodiment, a method for using a surgical stapler can comprise: creating relative motion between a housing and a trigger of a surgical stapler by placing a load on the surgical stapler; contacting a surface of the trigger with a cartridge comprising staple pins; releasing a staple pin from the cartridge and folding ends of the staple pin; releasing the load; and biasing the housing and trigger apart with the thermoplastic leaf spring.
