Abstract:
1. A medical knife assembly, comprising: a neonatal clamping arrangement having a cutting blade pivotally attached thereto; a maternal clamping arrangement, said maternal clamping arrangement being releasably secured to said neonatal clamping arrangement by a plurality of shear pins; said shear pins being aligned in a parallel plane and perpendicular to said cutting blade to facilitate their shearing to affect separation of said neonatal clamping arrangement from said maternal clamping arrangement; said neonatal clamping arrangement includes an inner clamping member and an outer clamping member; and said maternal clamping arrangement includes another inner clamping member and another outer clamping member; said inner clamping member and said another inner clamping member being temporarily secured together by an individual one of said plurality of shear pins; said outer clamping member and said another outer clamping member being temporarily secured together by at least another one of said plurality of shear pins; wherein said inner clamping member and said another inner clamping member are pivotally connected to said outer clamping member and said another outer clamping member to effect relative pivotal motion therebetween; wherein said cutting blade is pivotally mounted and releasaibly secured between said inner clamping member and said another inner clamping member; wherein said cutting blade includes a base member having a circular spline on an outer face thereof; said circular spline interlocking with another spline disposed on an adjacent inner clamping member to permit pivotal motion between said cutting blade and said adjacent inner clamping member in one rotational direction only.
