Abstract：The utility model provides an auxiliary medical instrument for dredging a fallopian tube. The auxiliary medical instrument comprises a body, supporting legs and trundles. The body is rectangular, andsupporting legs are fixed to the bottom of the body through bolts. Trundles are fixed to the bottoms of the supporting legs through bolts. Sliding rails are arranged on the front side and the rear side of the bottom of the body correspondingly, and the two sliding rails are symmetrical front and back. Sliding rail supports are embedded in the left end and the right end of the sliding rail correspondingly and fixed to the bottom face of the body through bolts. A headrest is placed on the left side of the top of the body; an n-shaped hip bracket is arranged at the top of the body, and the body is arranged on the inner side of the hip bracket in a sleeving mode in a clearance fit mode. The hip bracket is connected with the sliding rail through the sliding seat; the hip support has the advantages of being simple and reasonable in structure, flexibly adjusting the position of the hip support in a sliding mode and providing convenience for a patient, thereby effectively solving the problemsand defects in an existing device.
