Surgical suturing instrument and method

A surgical instrument for joining body tissue within a body cavity, comprising:

• a clip-like or staple-like surgical device having tissue piercing structure, said surgical device having an open condition and being plastically deformable by said surgical instrument from said open condition into a closed condition in which closed condition said device is substantially maintained due to plastic deformation thereof;
• means for holding said surgical device in said open condition and for deforming said device into said closed condition to pierce and join said body tissue together;
• activating means for activating said holding and deforming means to deform said device into said closed condition, said activating means including an activator spaced from said holding and deforming means and elongate movable means for coupling said activator with said holding and deforming means;
• elongate frame means for enclosing at least a substantial part of said coupling means, said coupling means being movable relative to said frame means;
• and
• means for sealing fluid-tight within said frame means one side of said frame means on which said holding and deforming means are disposed from another side of said frame means on which said activator is disposed while permitting movement of said coupling means relative to said frame means.

A surgical instrument for stapling body tissue within a body cavity, comprising:

• an elongate frame;
• staple holding and applying means for holding a plastically deformable surgical staple in a first orientation generally parallel to said frame in an open condition of said staple, for moving said staple to a second orientation transverse to said elongate frame, and for closing said staple to pierce and join said body tissue together;
• activating means for activating said staple holding and applying means to reorient and apply said staple to said body tissue, said activating means including an activator spaced from said staple holding and applying means and movable means for coupling said activator with said staple holding and applying means;
• said elongate frame enclosing at least a substantial part of said coupling means, said coupling means being movable relative to said frame;
• and
• means for sealing fluid-tight within said frame one side of said frame on which said staple holding and applying means are disposed from another side of said frame on which said activator is disposed while permitting movement of said coupling means relative to said frame.

A surgical stapling instrument for stapling body tissue within a body cavity, comprising:

• an elongate frame;
• stapling means for holding a generally U-shaped, plastically deformable surgical staple in a first orientation generally parallel to said frame in an open condition of said staple, for moving said staple to a second orientation transverse to said elongate frame, and for plastically deforming said staple such that ends of said staple pierce the body tissue and staple the body tissue together in cooperation with deformation of said staple;
• activating means for activating said stapling means to reorient and apply said staple to said body tissue, said activating means including an activator spaced from said stapling means and movable means coupling said activator with said stapling means;
• said elongate frame enclosing at lest a substantial part of said coupling means, said coupling means being movable relative to said frame.

A surgical instrument for joining body tissue within a body cavity, comprising:

• a plurality of clip-like or staple-like surgical devices each having tissue piercing structure, said surgical devices each having an open condition and each said device being plastically deformable by said surgical instrument from an open condition into a closed condition in which closed condition said device is substantially maintained due to plastic deformation thereof;
• means for holding a one of said surgical devices in said open condition and for deforming said one device into said closed condition to pierce and join said body tissue together;
• activating means for activating said holding and deforming means to deform said one device into said closed condition, said activating means including an activator spaced from said holding and deforming means and elongate movable means for coupling said activator with said holding and deforming means;
• elongate frame means for enclosing at least a substantial part of said coupling means, said coupling means being movable relative to said frame means;
• means for storing at least another staple in said frame and for selectively moving said staple to said holding and deforming means for engagement thereby;
• and
• means for sealing fluid-tight within said frame means one side of said frame means on which said holding and deforming means are disposed from another side of said frame means on which said activator is disposed while permitting movement of said coupling means relative to said frame means.

A surgical stapling instrument for stapling body tissue within a body cavity, comprising:

• an elongate frame;
• stapling means for holding a generally U-shaped, plastically deformable surgical staple in a first orientation generally parallel to said frame in an open condition of said staple, for moving said staple to a second orientation transverse to said elongate frame, and for plastically deforming said staple such that ends of said staple pierce the body tissue and staple the body tissue together in cooperation with deformation of said staple;
• activating means for activating said stapling means to reorient and applying said staple to said body tissue, said activating means including an activator spaced from said stapling means and movable means coupling said activator with said stapling means;
• means for storing at least another staple in said frame and for selectively moving said staple to said stapling means when a staple is not engaged by said stapling means for engagement thereby;
• said elongate frame enclosing at least a substantial part of said coupling means, said coupling means being movable relative to said frame.
