Abstract:
1. A medical clamp comprising: a first half clamp body having an internal semicircular, axial cross section and a first planar flange extending therefrom said body that resides along a longitudinal axis thereof, and a first set of hinge arms formed thereon said flange with a hinge pin orifice formed therethrough; a second half clamp body having an internal semicircular, axial cross section and a second planar flange extending therefrom said body that resides along a longitudinal axis thereof and a second set of hinge arms formed thereon said second planar flange with a hinge pin orifice formed therethrough; a compression spring; a pivot pin; and a thumbscrew for adjusting the minimum closed internal diameter of the clamp without interfering with the opening of the clamp; wherein said first set of hinge arms are interleaved with said second set of hinge arms, and said pivot pin passes through said first set of hinge arm's a hinge pin orifices and through said second set of hinge arm's hinge pin orifices, wherein said first and said second half clamp bodies each have a longitudinal axis and a diameter of said axial cross section that decreases along the longitudinal axis of said bodies so as to form an internal tapered bore, wherein said pivot pin lies between said spring and said clamp's internal bore, and wherein said compression spring is positioned about said thumbscrew, between said first planar flange and said second planar flange so as to exert pressure on said flanges and cause said first half clamp body and said second half clamp body to pivot about said hinge pin, and wherein said first planar flan e has a threaded bore formed therethrough, said second planar flange has an orifice formed therethrough and said threaded thumbscrew passes through said orifice and matingly engages said threaded bore.
