distraction mechanism and a drainage mechanism. The support mechanism comprises a U-shaped frame, a
hydraulic cylinder, a bottom plate, an electric push rod, a sleeve, a rotating shaft and a driving motor; the
distraction mechanism comprises an adjusting part and a pair ofdistraction parts, and the adjusting part comprises a U-shaped seat, an L-shaped fixed rod, a stepping motor, a screw rod and a sliding block; and each distraction part comprises a hinge chain, a first sliding cylinder, a first spring rod, a second sliding cylinder, a second spring rod, a sliding rod and a reset spring; and the drainage mechanism comprises a telescopic rod, a drainage tube, an
infusion pump, a catch box, a spring lock bolt and a fixing ring. By adopting the support mechanism, the distraction mechanism and the drainage mechanism, the
surgical incision of a patient can be effectively opened and fixedly supported, the situation that the device
tears the
skin of the patient in the process of opening the
surgical incision of the patient can be effectively avoided, and hydrops in the
