    摘要： An apparatus for use in assisted parturition of livestock. The apparatus comprises a single synthetic rope formed to have two small loops and one large loop. The small loops are adjustable when the loops are not under tension, and fixed when under tension. The small loops are for attachment to a fetus' forelimbs within its mother's uterus. The large loop remains outside of the birth canal and serve to transmit a traction force to the small loops for pulling the fetus through the birth canal. The fixed size of the small loops during use of the apparatus and the non-abrasive, synthetic rope reduces danger of injury to fetus and mother during assisted parturition.
