Skin stapler

Claim 2

A surgical stapler comprising a housing, means for forming a staple, said forming means having an anvil surface terminating in a movable flange and a staple forming track movable containing a forming blade, said anvil surface having a boss and said forming blade having an opening, said anvil surface boss having an arcuate motion dependent on the linear motion of said forming blade opening such that said boss moves into said opening as said forming blade approaches said flange, and said boss moves out of said opening as said forming blade retracts from said flange, a staple feed track movably containing a plurality of staples in a point-to-crown configuration, the holding portion of said feed track being substantially parallel to said forming track and the distal, escaping, portion of said feed track being in substantial alignment with the distal portion of said forming track, and means for activating said forming means said activating means being cooperatively attached to said forming means.

Claim 3

A surgical stapler as in claim 1 further comprising a formed staple stripping surface adjacent at least two opposing sides of said anvil flange and wherein said stationary stripping surface is contained on said housing.

Claim 4

A surgical stapler as in claim 1 wherein said housing has a handle.

Claim 5

A surgical stapler as in claim 3 wherein said anvil surface and flange is biased relative to said forming blade.

Claim 6

A surgical stapler as in claim 4 wherein said anvil surface and flange is cantilevered.

Claim 7

A surgical stapler as in claim 5 wherein said boss moves into said opening essentially after zero travel of said forming blade toward said anvil flange such that said anvil flange is in substantial alignment with said forming blade before or as the distal portion of said forming blade contacts the proximal staple from said plurality of staples.

Claim 8

A surgical stapler as in claim 3 wherein said boss moves into said opening essentially after zero travel of said forming blade toward said anvil flange such that said anvil flange is in substantial alignment with said forming blade before or as the distal portion of said forming blade contacts the proximal staple from said plurality of staples.

Claim 9

A surgical stapler comprising means for forming a staple, said forming means having an anvil surface terminating in a movable flange and a staple forming track movably containing a forming blade, said anvil surface having a boss and said forming blade having an opening, said anvil surface boss having an arcuate motion dependent upon the linear motion of said forming blade opening such that said boss moves into said opening as said forming blade approaches said flange, and said boss moves out of said opening as said forming blade retracts from said flange so that said anvil flange is in substantial alignment with said forming blade when said boss is in said opening so that a staple can be formed on said anvil flange by said forming blade, a staple feed track movably containing a plurality of staples in a point-to-crown configuration, the holding portion of said feed track being in substantial alignment with the distal portion of said forming track, and means for activating said forming means, said activating means being cooperatively attached to said forming means.

Claim 10

A surgical stapler comprising means for forming a staple, said forming means having an anvil surface terminating in a movable flange and a staple forming track movably containing a forming blade, said anvil surface having a boss and said forming blade having an opening, said anvil surface boss having an arcuate motion dependent upon the linear motion of said forming blade opening such that said boss moves into said opening as said forming blade approaches said flange, and said boss moves out of said opening as said forming blade retracts from said flange so that said anvil flange is in substantial alignment with said forming blade when said boss is in said opening so that a staple can be formed on said anvil flange by said forming blade, a staple feed track movably containing a plurality of staples in a point-to-crown configuration, the holding portion of said feed track being in substantial alignment with the distal portion of said forming track, and means for activating said forming means, said activating means being cooperatively attached to said forming means.

Claim 11

A surgical stapler as in claim 8 wherein said boss moves into said opening essentially after zero travel of said forming blade toward said anvil flange such that said anvil flange is in substantial alignment with said forming blade before or as the distal portion of said forming blade contacts the proximal staple from said plurality of staples.

Claim 12

A surgical stapler as in claim 8 wherein said anvil surface and flange are biased relative to said forming blade.

Claim 13

A surgical stapler as in claim 10 wherein said anvil surface and flange are cantilevered.

Claim 14

A surgical stapler as in claim 11 wherein said boss moves into said opening essentially after zero travel of said forming blade toward said anvil flange such that said anvil flange is in substantial alignment with said forming blade before or as the distal portion of said forming blade contacts the proximal staple from said plurality of staples.
