Subepidermal staple connecting device and method for body tissue

PURPOSE: To connect to both parts to each other of a medium by mutually two end parts of a medium by an engaging device to produce irregular or wavy shape at the time of mutually moving a jaw to be engaged with the respective opposite parts of a mediuym like a body skin tissue. CONSTITUTION: Extention parts 18, 20 are arranged in contact with the upper surface of the skin and generally parallel thereto. In order to close an opening of the skin, the extention parts 18, 20 are moved downward to the skin, and piercing chips 22, 24, 26 are a little pierced through the skin.
