Mooney Ring Spreader, Single Cut. After a single cut is made, the instrument's gently curving jaws slide easily beneath the strangulating band or ring. Squeezing the handles together spreads the constriction, allowing quick removal with no additional trauma. Fits easily under embedded constrictions. Note: Not for use with Titanium, tungsten or cobalt constrictions. Two cuts must be made with the GEM Ring Cutting System. UOM: 1/EA.
