Abstract

A minimally invasive medical stapling device comprises a housing that contains spring-loaded staples for use in a minimally invasive medical stapling procedure. When the physician pulls a shutter the springs are sequentially released causing the staples to be fired. The device provides the user with tactile and audible feedback as the staples are fired.

Claims

1. A staple cartridge of a minimally invasive medical stapling device comprising:

a cartridge body complementary to and removably attachable to a housing of a full thickness resectioning device, the cartridge body defining staple containing cavities containing staples; and

staple drivers slidably retained in the cartridge body, the staple drivers having a staple end to propel staples from the staple containing cavities when the staple drivers are displaced, and a driven end adapted to cooperate with springs disposed in the housing when the cartridge body is attached to the housing, wherein successive staple drivers are sequentially displaced by shutter release of the springs.

2. The staple cartridge according to claim 1, wherein the staple drivers are adapted to slide in guides formed in the cartridge body to push staples out of the staple containing cavities.
