The invention discloses a multifunctional rectal lifting device. The multifunctional rectal lifting device comprises a bent guide rod, a bent lifting rod and a movable
handle; the lifting rod is rotationally connected with the guide rod; the guide rod is rotationally connected with the movable
handle; the lifting rod is provided with a
medicine injection hole and a first conveying mechanism for conveying medicines to the
medicine injection hole; the multifunctional rectal lifting device further comprises a transmission mechanism for driving the lifting rod to swing relative to the guide rod; and the transmission mechanism is connected with the lifting rod and the movable
handle, so that the movable handle can drive the lifting rod to swing. The bent lifting rod and guide rod meet a bent physiological status of the
rectum, so that the position is effectively adjusted; the lifting rod can be adjusted by the transmission mechanism in operation to finish up-down and left-right actions on the
rectum so as to reach the best operation position; gaps around the
rectum are fully exposed, so that the effectiveness and reliability are enhanced, the
surgical operation is facilitated, and the operation efficiency is improved; and further, the device has the function of injecting the medicines while adjusting the position of the rectum, so that the rectal injury can be reduced, the usabilityand convenience are enhanced, and the operation risk is lowered.
