A surgical stapler for suturing tissue that includes a flat driver slidably mounted in a stapler frame in operative association with a substantially flat anvil rotatably mounted in the frame. The anvil includes a projection, or flange, that is located near the nose of the stapler frame. The driver has a staple-forming recess at the nose area. The anvil is rotated by activation of the driver via a trigger mounted in the frame means. When the anvil is rotated from a non-engaged position to an engaged position by action of the driver, the projection of the anvil drops on the inner side of a staple in the recess. Further outward movement of the driver crimps the staple in the recess between the projection and the driver. De-engagement of the driver from the staple results in forcing the anvil to rotate from the engaged position to the non-engaged position so as to free the crimped staple from its position in the recess.

A surgical stapler for suturing tissue by at least one staple, comprising: frame means adapted to be held by a hand and having a nose, said frame means being for holding the staple and for directing the staple at the tissue site, said frame means having a hand grip, pivot means connected to said frame means, anvil means mounted in said frame means near said nose pivotably movable about said pivot means between non-engaged and engaged positions, driver means movably mounted in said frame means in operative association with said anvil means, said driver means having a crimping recess proximate said nose, the staple being capable of being shaped from an open staple to a crimped staple, said driver means being for forming said crimped staple in association with said anvil means in said crimping recess, said driver means being movable between activated and deactivated positions, wherein in said activated position said driver means has forced said anvil means from said non-engaged position to said engaged position, and wherein in said deactivated position said driver means has forced said anvil means from said engaged position to said non-engaged position, trigger means movable mounted to said frame means for activating said driver means for movement from said deactivated position to said activated position and simultaneously activating said anvil means for pivotable movement about said pivot means between said non-engaged position and said engaged position, said trigger means being adapted to manual activation, first camming means associated with said anvil means and said driver means for camming said anvil means into operative relationship with said driver means about said pivot means so that said anvil means is moved from said non-engaged position to said engaged position upon activation of said driver means for movement from said deactivated position to said activated position, and second camming means associated with said anvil means and said driver means for camming said anvil means about said pivot means so that said anvil means is moved from said non-engaged position to said engaged position upon activation of said driver means for movement from said deactivated position to said activated position.
