Title: METHOD AND DEVICE FOR LOADING A STAPLE GUIDE
Abstract:
A method of loading a staple guide (20) into a shell assembly (18) of a stapling device (10) includes clamping the stapling device to a loading station (60); actuating a first press (74) to operate a firing trigger (26) to advance a pusher back (38) of the shell assembly to a partially fired position; manually placing the staple guide adjacent a distal end of a shell housing (30) such that fingers (44) of the pusher back are received within staple receiving slots (28) of the staple guide; and actuating a second press (76) to advance a press tool (92) into the distal end of the shell housing to load the staple guide into the shell housing and returning the pusher back to its retracted position. A device for loading a staple guide into a shell assembly of a circular stapling device includes a loading station (60) having a base member (100), a clamp mechanism (62, 64, 66) configured to secure the stapling device to the base member, a first press (74) that can be actuated to operate a firing trigger (26) of the stapling device, and a second press (76). The second press when actuated simultaneously advances a press tool (92) into a shell housing (30) of the shell assembly to insert the staple guide into the shell housing and retracts a pusher back (38) of the shell assembly to a retracted position to maintain alignment between the pusher back and the staple guide.
