The invention provides a spine
tractor which comprises a main body support, a sliding part, a lifting mechanism, a
molar tooth supporting plate and a first
bandage, and the sliding part is slidably connected with the main body support in the vertical direction; the lifting mechanism is used for driving the sliding piece to slide; the
molar supporting plate is fixedly connected with the sliding piece, and the
molar supporting plate is provided with a supporting part which is used for being placed in an
oral cavity to support molar teeth; the first binding band is fixedly connected with the sliding piece and used for binding the head of a user to the sliding piece. The fixing tube, the sliding part and the molar supporting plate are arranged, the traction force application point is changed into a molar area from the neck, compression of neck blood vessels and muscles is avoided, it is ensured that a patient with angiosclerosis can also safely use the device, and due to the fact that the requirement for stability of stress at the molar is high, stable upward traction force can be provided through a telescopic structure, and the traction effect is good. The damage to the head caused by shaking or inclination of the molar supporting plate is avoided.
