The invention relates to the field of medical equipment in the obstetrics department, in particular to a hemostasis assistance device for an abortion operation. The device comprises a hemostasis bag and an airbag, a sponge layer, a medicine agent layer, a function layer and a medicine agent cavity are arranged between the hemostasis bag and the airbag in sequence from outside to inside, during use, the air bag is inflated through an inflation device, and under supporting of a supporting column, the hemostasis bag is expanded to abut against the endometrium, and hemostasis by compression is achieved; the function layer of the hemostasis assistance device for the abortion operation comprises a plurality of heating assemblies and ultrasonic wave vibration pieces which are arranged at intervals; the ultrasonic wave vibration pieces are controlled by a controller to vibrate and beat the medicine agent layer and the sponge layer, so that a hemostasis medicine on the medicine agent layer andthe sponge layer is atomized and more quickly absorbed by the uterus; meanwhile, the controller controls the heating assemblies to heat the medicine liquid, macromolecules in the atomized medicine liquid are further decomposed into small molecules to form small-particle-size negative ions, and through atomization and ionization, the medicine liquid is more easily absorbed by the uterus. In addition, the temperature control effect can relieve the pains of a patient.
