ABSTRACT:
A ligature tool, of the type having a handle carrying an elongate body defining a fastening clip chamber in its forward part with ligature tubing holding and tensioning means carried on the body, provides improved crimping and tubing holding means. The crimping element provides a single pivotally mounted crimping dog that contacts a slit portion of an annular ligation tube clip carried in the fastening clip chamber and is movable into that chamber to crimp the sides defining the slit toward the adjacent inner surfaces of the annular clip body to fasten ligation material therebetween. The tubing holding means provide a body supporting similar laterally opposed tubing holders each having a headed vertical post about which the end portion of tubing is wound under tension before placement in an adjacent wedge-shaped slot for releasable fastening. The tubing holding body also provides tubing cutting structure.
