Patent number: 7959052Abstract: The invention is a stapler device comprising an anvil and staple cartridge located in the distal tip of an endoscopic device. The staple cartridge is comprised of a fixed proximal portion and a moveable distal portion, which slides into said fixed portion. Means are provided for moving the anvil back and forth, such that the anvil pushes against the distal face of the staple cartridge thereby pushing the moveable portion of the staple cartridge into the fixed portion and causing the staples to be ejected from said staple cartridge passively without said staples moving. The stapler of the invention has two embodiments, a side fastening embodiment and a front fastening embodiment. The endoscopic device that comprises the stapler can be used to perform many different stapling tasks, e.g. closure of a hole in the wall of an internal organ.Type: GrantFiled: May 31, 2007Date of Patent: June 14, 2011Assignee: Medigus Ltd.Inventors: Elazar Sonnenschein, Amir Govrin

Patent number: 7753249Abstract: The invention is a stapling device comprised of an articulation section having a staple cartridge containing staples and parts of a staple-firing mechanism located at one end and an anvil portion located at the other end. The front surfaces of the anvil and the cartridge are curved. When the articulation section is bent the curved front surfaces of the anvil and the cartridge are brought opposite each other. As the distance between said curved surfaces is reduced, their curvature helps to correct transverse misalignment and to bring the anvil and the cartridge into the correct working relationship.Type: GrantFiled: February 15, 2005Date of Patent: July 13, 2010Assignee: Medigus Ltd.Inventors: Minelu Sonnenschein, Elazar Sonnenschein, Amir Govrin
