1. A surgical apparatus comprising:
- a handle;
an elongate shaft connected at a proximal end thereof to said handle and extending distally from said handle, said elongate shaft defining a longitudinal axis and supporting at a distal end thereof a cartridge assembly containing surgical staples and defining a tissue contacting surface having openings through which said surgical staples are ejected, said tissue contacting surface extending parallel to said longitudinal axis of said elongate shaft;
an anvil assembly including an elongate anvil body having an anvil surface with a plurality of staple deforming depressions for receiving and forming surgical staples and a spring member extending longitudinally from said elongate anvil body, said anvil assembly adapted to pivotally engage said elongate shaft adjacent the distal end thereof.

Abstract
A surgical stapler for placing lateral lines of staples and making an incision, all through an endoscopic tube, includes an anvil member which is mounted to the distal end of an elongated housing. A tubular collar disposed around the arm of the anvil member is movable to a distal position to bias the anvil member and a cartridge assembly into cooperative alignment, thereby clamping body tissue to be fastened between the anvil member and cartridge assembly.

8. A surgical stapler apparatus comprising:
-
a handle section; an elongate shaft connected at a proximal end thereof to said handle section and extending distally from said handle section, said elongate shaft defining a longitudinal axis and including a movable camming tube having a transverse camming surface and said elongate shaft supporting at a distal end thereof a cartridge assembly containing surgical staples and defining a tissue contacting surface having openings through which said surgical staples are ejected, said tissue contacting surface extending parallel to said longitudinal axis of said elongate shaft; an anvil assembly including an elongate anvil body having a camming surface and an anvil surface with a plurality of staple deforming depressions for receiving and forming surgical staples and a spring member extending longitudinally from said elongate anvil body and angled relative thereto, said anvil assembly having a pair of pivots adjacent the end of said spring member distal to said elongate anvil body for pivotally engaging said elongate shaft adjacent the distal end thereof, said transverse camming surface of said camming tube contacting said anvil camming surface to pivot said anvil assembly relative to said elongate shaft to position said anvil surface opposite said cartridge assembly. - View Dependent Claims (9, 10, 11, 12, 13)
