Abstract
A hand-held surgical stapler is provided having a reduced distal profile due to a unique feeding means. A combination of features allows the reduced distal profile. The staple storage cover can be of reduced distal thickness due to the slope effect. The staple pusher has the capability at its distal end to push and by pushing lift all of the staples, including the last, into the staple track. Provisions are made on the staple pusher to allow the form tool to displace it out of the staple track to allow forming of the last staple. Nose assemblies are disclosed which can be interchangeably mounted to various trigger assemblies. The pre-load on the stored staples can be varied. A ratchet feature requires full depression of the trigger before it can be returned to a neutral or extended position and full extension of the trigger to its neutral position prior to initiation of the next staple feed cycle.
