The application of a ligature to control hemorrhage from a blood vessel in a deep cavity, such as the throat, the chest or the abdomen, is sometimes no easy matter to the surgeon. To facilitate easier ligation of bleeding points of tissues in these relatively inaccessible regions, as in operations pertaining to the tonsils, the gallbladder, the spleen, the kidneys or the lungs, instrumental methods of tying knots are often resorted to.
The knot-tying instrument here presented is simple in construction. It is inexpensive, practical and efficient. It is made of a long slender rod with two eyes on the nose at one end of it. The partition between the two eyes on the nose of this knot-tyer acts as the fulcrum, and all the force to be exerted in an easier knot-tying is being borne by this device, which eliminates simultaneously the posibility of tearing tissue free from the
