An Improved Shot Compressor. By JOHN S. MILLER, M.D., SURGEON TO ST. JOSEPH'S HOSPITAL, PHILADELPHIA, PA. Reprinted from the Medical Record, December io, 1892. Complicated surgical instru- ments, even if efficient, are not generally welcome to the surgeon. Simplification of all details in mechanism favors their aseptic prepara- tion which is most desira- ble. If an instrument can be made to do the work of two, and its mechanism is not complicated thereby, we would believe this to be an effort in the right direction. In gynecological operations where silkworm gut-or any other form of suture-is used with shot, a shot compres- sor is required, and also a pair of scissors to cut off the ends of the sutures. The instrument depicted in the woodcut is simply an ordi- nary shot compressor with semi - circular cutting edges at the points of both jaws. After the shot is compressed the instrument is slightly withdrawn and the suture is cut off, thereby saving time and lessening the number of instruments. 1917 Girard Avenue.
