fetotome

fetotome

an instrument designed for use in cows and mares for the purpose of dissecting a dead fetus in utero when normal delivery is impossible and cesarean section inadvisable. There are a number of special instruments all based on fetotomy wire saws passed through metal tubes about 3 ft long. These are threaded external to the cow by passing the wire saw out of the end of one tube, into the uterus and around the part to be amputated, out of the uterus and into the other tube. The two ends of the saw are brought out of the far ends of the tubes and special handles are attached. The tubes are inserted into the uterus and pushed hard up against the skin. Rapid see-sawing with the saw completes the task.

A good quality Thygesen's fetotome loaded with a strong and flexible fetotomy saw wire (27 interwoven steel wires in a group of 3 x 3 x 3 wires) to cut through soft and bony tissues of fetus.
The fetotome with saw wire was introduced around the one head of the fetus and removed by cutting it.
Sufficient traction was given using long blunt obstestical hook in right eye orbit and over ropes of both fore limbs and neck region but fetus did not progress beyond shoulder region hence it was opted for fetotomy using thygeson's fetotome.
