Abstract

The tractor is introduced closed into the bladder, through a slit in the membranous urethra, and is then opened by turning the thumb-screw five or six times to the left. Then slide the large nut back to the thumbscrew, and hold it with the right hand while the shaft is turned to the left with the left hand until the groove on the nut is in line with the groove on the shaft. Then slide the large nut back to its place and lock by turning the thumbscrew to the right. The end of the tractor is now elevated and the instrument is used as a lever; the pubes being the fulcrum of the lever and the prostate the body moved. This maneuver brings the broad flat surfaces of the blades of the instrument in contact with the bladder wall through which the force must be applied to the prostate. The tractor is taken apart for cleaning by simply removing the thumbscrew.
