Abstract:
1. A stapling apparatus for performing anastomosis on hollow organs, comprising: an L-shaped clip retainer tool including an elongated clip retainer handle with a clip retaining foot extending laterally from a bottom distal end of said handle; said clip retaining foot having a C-shaped clip jaw disposed in a plane transverse to said clip retainer handle and defining a first organ exit gap and with a side face thereof providing an upwardly facing top face, a clip retainer provided in said C-shaped clip jaw and having a series of staple receiving and retaining clips received in and arranged circumferentially along an upwardly facing top face of said clip retainer corresponding with said upwardly facing top face of said C-shaped clip jaw whereby a hollow organ end to be stapled is able to be circumferentially surrounded by said staple receiving and retaining clips; an L-shaped staple retainer tool guidably detachable from and engageable with said L-shaped clip retainer tool by a guide for stapling registration therewith, and including an elongated staple retainer handle with a staple retaining foot extending laterally from a bottom distal end of said staple retaining handle; said staple retaining foot having a C-shaped staple jaw disposed in a plane transverse to said staple retainer handle and defining a second organ exit gap and with a side face thereof providing a downwardly facing bottom face, a staple retainer provided in said C-shaped staple jaw and having a series of staple sockets arranged circumferentially along a downwardly facing bottom face thereof for retaining a series of staples with penetrating tips of said staples exposed from said bottom face of said C-shaped staple jaw whereby a hollow organ end to be stapled is able to be circumferentially surrounded by said staples, said staples positioned in stapling registration with respective of said staple receiving and retaining clips in said clip retainer and said organ exit gaps aligned with said bottom face of said C-shaped staple jaw aligned with and positioned in stapling registration over said top face of said C-shaped clip jaw when said L-shaped clip retainer tool and said L-shaped staple retainer tool are guidably engaged by said guide with each other in stapling registration; a spaced series of pins extending from said C-shaped clip and staple jaws for piercing and retaining respective hollow organ ends by respective of said C-shaped clip and staple jaws with the organ ends respectively stretched over said top and bottom faces of said clip and staple retainers for stapling; a clamp for clamping said clip retainer and staple retainer tools together when guidably engaged with said guide with said top and bottom faces respectively of said C-shaped clip and staple jaws facing each other in stapling registration and with the hollow organ ends respectively applied over said clip and staple retainer top and bottom faces; a staple firing mechanism for engaging said staples from a top face of said staple retainer and pushing said staples downwardly in said staple sockets into stapled engagement with respective of said staple receiving and retaining clips.
