Abstract

A fastener applying device including a staple housing having a proximal end attached to a handle, a distal end, and a longitudinal axis therebetween. There is at least one fastener within the housing. The device also includes an anvil movable within the staple housing. The anvil has a proximal position and a distal position, wherein when in the distal position a distal end of the anvil extends distal to the distal end of the staple housing by a distance. The device also includes an adjustment nut connecting the staple housing to the handle. Rotation of the adjustment nut changes the distance.

Claims

1. A fastener applying device comprising:

a. a staple housing having a proximal end attached to a handle, a distal end and a longitudinal axis therebetween;

b. at least one fastener within said housing;

c. an anvil movable within said staple housing, said anvil having a proximal position and a distal position, wherein when in said distal position a distal end of said anvil extends distal to said distal end of said staple housing by a distance; and

d. an adjustment nut connecting said staple housing to said handle, wherein rotation of said adjustment nut changes said distance.
