Abstract

Abstract The present invention is directed to a surgical suture instrument specifically designed for suturing body tissues in enclosed surgical operations. The instrument includes a casing with a slot or housing a suture needle. The needle includes a first puncture end and a second manipulation end. The needle is pivotally positioned on an axis within the casing, such that the puncture end may be exposed or retracted as needed. The casing also includes equipment to manipulate the needle within the casing.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 107 words
A surgical suture instrument, which comprises: a) a shaft; b) a suture needle having a tapered portion and a base portion, said base portion extending from the shaft and being generally longitudinally fixed relative thereto; and c) means disposed on the shaft for shielding the tapered end portion, whereby the shielding means and the tapered end portion are relatively positionable from a first orientation to shield the tapered end portion to a second orientation to expose the tapered end portion such that said needle base portion remains generally radially fixed relative to the shield means during such relative positioning from said first orientation to said second orientation.
Claim 2
Dependent Claim 107 words
A surgical suture instrument, which comprises: a) a shaft; b) a suture needle having a tapered portion and a base portion, said base portion extending from the shaft and being generally longitudinally fixed relative thereto; and c) means disposed on the shaft for shielding the tapered end portion, whereby the shielding means and the tapered end portion are relatively positionable from a first orientation to shield the tapered end portion to a second orientation to expose the tapered end portion such that said needle base portion remains generally radially fixed relative to the shield means during such relative positioning from said first orientation to said second orientation.
Claim 3
Dependent Claim 13 words
A surgical suture instrument according to claim 1, wherein said needle is curved.
Claim 4
Dependent Claim 13 words
A surgical suture instrument according to claim 2, wherein said needle is C-shaped.
Claim 5
Dependent Claim 13 words
A surgical suture instrument according to claim 1, wherein said needle is pivotable.
Claim 6
Dependent Claim 26 words
A surgical suture instrument according to claim 1, wherein said needle is oriented with said puncture end portion directed toward said proximal end of said shaft.
Claim 7
Dependent Claim 183 words
A surgical suture instrument, comprising: a) an elongated housing defining an opening; b) a suture needle connected to said elongated housing and having a puncture end and a manipulation end, said needle being movable along an arcuate path from a first position to a second position, wherein when in the second position the needle is connected to the elongated housing and the puncture end is directed toward a proximal end of the elongated housing and is capable of piercing body tissue in such position; c) an actuator positioned within the elongated housing and longitudinally slidable in a distal direction to move the needle along such arcuate path from said first position to said second position; and d) means disposed on the housing for shielding the puncture end whereby the shielding means and the puncture end are relatively positionable from a first orientation to shield the puncture end to a second orientation to expose the puncture end such that the needle manipulation end remains generally radially fixed relative to the shield means during such relative positioning from said first orientation to said second orientation.
Claim 8
Dependent Claim 183 words
A surgical suture instrument, comprising: a) an elongated housing defining an opening; b) a suture needle connected to said elongated housing and having a puncture end and a manipulation end, said needle being movable along an arcuate path from a first position to a second position, wherein when in the second position the needle is connected to the elongated housing and the puncture end is directed toward a proximal end of the elongated housing and is capable of piercing body tissue in such position; c) an actuator positioned within the elongated housing and longitudinally slidable in a distal direction to move the needle along such arcuate path from said first position to said second position; and d) means disposed on the housing for shielding the puncture end whereby the shielding means and the puncture end are relatively positionable from a first orientation to shield the puncture end to a second orientation to expose the puncture end such that the needle manipulation end remains generally radially fixed relative to the shield means during such relative positioning from said first orientation to said second orientation.
Claim 9
Dependent Claim 19 words
A surgical suture instrument according to claim 6 wherein said suture needle is pivotably connected to said elongated housing.
Claim 10
Dependent Claim 21 words
A surgical suture instrument according to claim 6 wherein said suture needle includes a suture opening formed at said puncture end.
Claim 11
Dependent Claim 25 words
A surgical suture instrument according to claim 6, further comprising a finger grip portion extending from said elongated housing adjacent a proximal end portion thereof.
Claim 12
Independent Claim 197 words
A method of closing trocar puncture wounds, comprising the steps of: a) positioning a surgical suturing instrument at a suture site, the surgical suturing instrument including a shaft, a suture needle having a tapered portion and a base portion and an opening for receiving suture material, said base portion extending from the shaft and being longitudinally fixed relative thereto; b) inserting the surgical instrument into the wound to be sutured; c) retracting the surgical instrument toward the wound opening to urge the tapered portion of the needle to penetrate the body tissue such that the needle exits the tissue surrounding the wound and exposes the opening in the suture needle; d) inserting a suture material through the opening in the suture needle; e) reinserting the instrument into the wound opening to be sutured; f) rotating the instrument approximately 180°; g) retracting the surgical instrument from the wound to urge the tapered portion of the needle to penetrate the body tissue such that the needle exits the tissue surrounding the wound and exposes the opening in the suture needle; h) removing the instrument from the wound; and i) tying off the suture material to form a suture knot.
Claim 13
Independent Claim 197 words
A method of closing trocar puncture wounds, comprising the steps of: a) positioning a surgical suturing instrument at a suture site, the surgical suturing instrument including a shaft, a suture needle having a tapered portion and a base portion and an opening for receiving suture material, said base portion extending from the shaft and being longitudinally fixed relative thereto; b) inserting the surgical instrument into the wound to be sutured; c) retracting the surgical instrument toward the wound opening to urge the tapered portion of the needle to penetrate the body tissue such that the needle exits the tissue surrounding the wound and exposes the opening in the suture needle; d) inserting a suture material through the opening in the suture needle; e) reinserting the instrument into the wound opening to be sutured; f) rotating the instrument approximately 180°; g) retracting the surgical instrument from the wound to urge the tapered portion of the needle to penetrate the body tissue such that the needle exits the tissue surrounding the wound and exposes the opening in the suture needle; h) removing the instrument from the wound; and i) tying off the suture material to form a suture knot.
