Abstract
Abstract A surgical instrument is provided for suturing hollow organs in infants and comprises an oblong tubular body with an open tapered front end with staple slots spaced around the periphery thereof and an oblong hollow rod passes inside the body and is capable of axial movement therealong. A cylindrical staple ejector is loosely mounted on the rod and is provided with toothlike pins spaced around its periphery to fit into the slots in the body. An elastic member is mounted between the rod and the ejector so that a constant travel rate is obtained for the staple ejector. A stem is mounted inside the hollow rod so as to be free to move axially and to rotate around its own axis when extended all the way out of said body, the front end of the stem being pointed and supporting a detachable tapered head having a surface facing the body with staple bending depressions spaced around the periphery of the head.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
255 words
An instrument for suturing hollow organs in infants, said instrument comprising an elongated tubular body with an open tapered forward end having staple slots spaced along the periphery thereof; an elongated hollow rod passing inside said body and capable of axial movement with respect thereto; a cylindrical staple ejector freely mounted on said rod and including a plurality of peripherally arranged pins engaged in said slots in the body; a spring member between said rod and ejector to provide for relative movement between the rod and the ejector; a stem disposed inside said rod for axial movement, and for rotation about its axis in a fully extended position relative to the body, said stem having a pointed forward end extending out of the open forward end of the body and a rear portion; a supporting head detachably mounted on said pointed forward end of said stem and having a broad end portion facing rearward in the direction of the body, said end portion of the head having a cylindrical recess and staple bending depressions. said depressions being provided peripherally on the end portion of said head; means on said rod and said head for cutting tissues placed in said recess; means coupling said stem with the body for holding the stem in the body and manually actuated means for axially moving said rod and ejector in said body so that staples in said slots are pushed out of said slots to puncture the tissues to be sutured and be bent in said staple bending depressions.
Claim 2
Dependent Claim
255 words
An instrument for suturing hollow organs in infants, said instrument comprising an elongated tubular body with an open tapered forward end having staple slots spaced along the periphery thereof; an elongated hollow rod passing inside said body and capable of axial movement with respect thereto; a cylindrical staple ejector freely mounted on said rod and including a plurality of peripherally arranged pins engaged in said slots in the body; a spring member between said rod and ejector to provide for relative movement between the rod and the ejector; a stem disposed inside said rod for axial movement, and for rotation about its axis in a fully extended position relative to the body, said stem having a pointed forward end extending out of the open forward end of the body and a rear portion; a supporting head detachably mounted on said pointed forward end of said stem and having a broad end portion facing rearward in the direction of the body, said end portion of the head having a cylindrical recess and staple bending depressions. said depressions being provided peripherally on the end portion of said head; means on said rod and said head for cutting tissues placed in said recess; means coupling said stem with the body for holding the stem in the body and manually actuated means for axially moving said rod and ejector in said body so that staples in said slots are pushed out of said slots to puncture the tissues to be sutured and be bent in said staple bending depressions.
Claim 3
Dependent Claim
49 words
An instrument as claimed in claim 17 wherein the means for cutting tissues comprises a puncher disposed inside the body and attached to the rod at the forward end thereof and interacting in operation with an edge of said cylindrical recess in the end portion of the supporting head.
Claim 4
Dependent Claim
45 words
An instrument as claimed in claim 2 wherein the spring member comprises a split washer freely mounted on the puncher and disposed inside said body between the forward end of said rod and the staple eJector, the latter also being freely mounted on the puncher.
Claim 5
Dependent Claim
32 words
An instrument as claimed in claim 2 wherein the puncher includes a cylindrical projection at the forward end thereof for forcing the sutured tissues into said cylindrical recess of the supporting head.
Claim 6
Dependent Claim

An instrument as claimed in claim 1 comprising a manually actuated knob on said rear portion of the stem with a roughened surface for moving the stem in said rod.
Claim 7
Dependent Claim
26 words
An instrument as claimed in claim 1 wherein said supporting head has flat regions on opposite sides thereof to allow reliable holding by a clamping means.
Claim 8
Dependent Claim
