Abstract
Abstract A surgical forceps moulded from plastic material having two arms forming a generally U-shaped configuration having a closed end and an open end, the arms extending in a longitudinal direction in a given plane and movable toward and away from each other in said plane, the arms being generally T-shaped in cross-section, the arms being joined at the closed end of the forceps by a thin hinge strip of resilient plastic material moulded integrally with the arms, said thin strip having a small thickness dimension extending in said longitudinal direction in said given plane, a width dimension, and a length dimension extending in and parallel to said given plane, said length being small in comparison to the width of the strip.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
A surgical forceps moulded from plastic material having two arms forming a generally U-shaped configuration having a closed end and an open end, the arms extending in a longitudinal direction and movable toward and away from each other, the arms being generally T-shaped in cross-section, the arms being joined at their inner ends at the closed end of the forceps by a thin hinge strip of resilient plastic material which resiliently holds the outer ends of the arms in spaced-apart relationship moulded integrally with the arms, said thin strip haVing a small thickness dimension extending in said longitudinal direction, a width dimension, and a length dimension connecting together the inner ends of the arms, said length dimension being small in comparison to the width of the strip and said thickness dimension being less than the thickness of one of said T-shaped arms.
Claim 2
Dependent Claim
142 words
A surgical forceps moulded from plastic material having two arms forming a generally U-shaped configuration having a closed end and an open end, the arms extending in a longitudinal direction and movable toward and away from each other, the arms being generally T-shaped in cross-section, the arms being joined at their inner ends at the closed end of the forceps by a thin hinge strip of resilient plastic material which resiliently holds the outer ends of the arms in spaced-apart relationship moulded integrally with the arms, said thin strip haVing a small thickness dimension extending in said longitudinal direction, a width dimension, and a length dimension connecting together the inner ends of the arms, said length dimension being small in comparison to the width of the strip and said thickness dimension being less than the thickness of one of said T-shaped arms.
Claim 3
Dependent Claim
25 words
A pair of surgical forceps as claimed in claim 1 wherein the web of said T-shaped cross-section tapers towards the closed end of said forceps.
Claim 4
Dependent Claim
20 words
A pair of surgical forceps as claimed in claim 1 or claim 2 including reinforcing means at said closed end.
Claim 5
Dependent Claim
30 words
A pair of surgical forceps according to claim 3 wherein said reinforcing means comprises integrally moulded blocks of plastic material on each side of each web adjacent said closed end.
Claim 6
Dependent Claim
63 words
A pair of surgical forceps as claimed in claim 1 wherein the web of each arm, adjacent the open end of said forceps, is provided with two projections displaced one to each side of the plane of said web, the arrangement being such that, as the forceps close, said projections interlock to prevent relative lateral displacement of the free ends of said arms.
Claim 7
Dependent Claim
81 words
A pair of surgical forceps as in claim 1 wherein the web of the T-shaped cross sections taper toward the closed end of the forceps and wherein reinforcing means for resisting sideways deflection of the arms are provided at the closed end, said reinforcing means comprising an integrally moulded block filling in the space on either side of each web adjacent the closed end of the forceps, each block being integral with its respective web and with said thin hinge strip.
Claim 8
Dependent Claim
24 words
A pair of surgical forceps as in claim 1 wherein the thickness dimension of the hinge strip is about equal to the length dimension.
