The invention relates to a novel multi-functional medical stretcher vehicle. The stretcher vehicle consists of a rolling table top 1, a table top supporting lifting system 2, a rotary bearing base plate 3, a rotary connecting drive structure 4 and a base plate system 5. By the stretcher vehicle, the height of the table top is automatically adjusted, the table top or the base plate is automatically rotated, and the length of the base plate is changed by automatically stretching and contracting the table top, so that the stretcher vehicle can enter a sickroom with a narrow space and a narrow clearance among sickbeds, can have the height consistent with that of the surface of the sickbed, an operating table top, a cart table top and an inspection table top and is parallelly close to the sickbed, an operating table, a cart table and an inspection table; through automatic rolling of the table top, a patient can be moved horizontally, so that the patient can be respectively moved transitionally from the stretcher vehicle to the sickbed, the inspection table, a stretcher vehicle and the operating table; therefore, labor intensity of medical staff is reduced, manpower and time are saved, dignity of the patient is maintained, patient pains are reduced, complication due to carrying is avoided, and the technological level and quality of the modern medical nursing service are improved.
