The invention provides a congenital hypertrophic pyloric stenosis treating electrocoagulation pyloric chisel. The congenital hypertrophic pyloric stenosis treating electrocoagulation pyloric chisel comprises a pyloric chisel body, a high-frequency electrotome and an electric wire; one end of the electric wire is electrically connected with the high-frequency electrotome, and the other end of the electric wire is electrically connected with the pyloric chisel body; the pyloric chisel body comprises a chisel handle module and a chisel rod module, the chisel handle module comprises a chisel handle body, an electric plug and a conductive core, the chisel rod module comprises a chisel head, a chisel rod and an insulating layer, the insulating layer is used for covering the outer surface of thechisel head and the chisel rod, the outer end of the chisel head is not covered by the insulating layer, one end of the chisel rod is electrically connected with the conductive core, and the other endof the chisel rod is connected with the chisel head. Through optimization design, the congenital hypertrophic pyloric stenosis treating electrocoagulation pyloric chisel structurally combines the pyloric chisel body with the electrotome and enables the pyloric chisel body to achieve electrosurgical cutting, electrocoagulation hemostasis and nondestructive separation of the chisel head, thereby reducing replacement of medical equipment during operation, shortening the time of operation and improving the success rate of operation and the therapeutic effects.
