The invention discloses a
spinal nerve injury preventing aspirator for a
spinal operation, and belongs to the field of
medical instruments. Comprising a collecting
bottle, the upper end of the collecting
bottle is in threaded connection with a sealing cover, the top end of the sealing cover is fixedly connected with a connector, the inner wall of the connector is fixedly connected with a connecting
pipe, the upper end of the sealing cover is fixedly connected with a liquid inlet
pipe, and a semicircular block is pulled to drive a connecting
rope to slide in a hollow rod and a second hollow grip. The connecting
rope drives the fixing ring to rotate, the angle of the suction head is adjusted while the fixing ring rotates, the suction head makes contact with liquid in the narrow area of the inner wall of the
spinal cord, then the liquid in the narrow area of the inner wall of the
spinal cord is sucked away through negative pressure equipment, and the liquid enters the hollow rod through the suction head. Then the blood is sucked into the collecting
bottle through the second hollow grip, the first hollow grip and the hose to be collected, and the suction head is beneficial to reducing friction and damage of the device to spinal nerves, so that the definition of the visual field of a worker in the operation process is improved.
