The invention discloses a negative-pressure fastening correction-type
skull traction device capable of being intelligently regulated and controlled. The device comprises a center connection part, a traction bow, a communicating vessel, a negative pressure generator, a fixing screw and a fixing
cushion block. The center connection part comprises a cylindrical shell, an MCU
chip, connection ports, abuilt-in wifi module and a battery, the communicating vessel is located above the center connection part, and the negative pressure generator is connected to the exterior of the communicating vessel;the upper end of the traction bow is connected with the connection ports separately, the fixing
cushion block is connected to the lower end of the traction bow, and a
pressure sensor is arranged in the fixing
cushion block; the fixing screw horizontally penetrates through the fixing cushion block, the interior of the fixing screw is hollow, and a suction hole is formed in the inner wall and connected with the communicating vessel through a hose. According to the device, the aim of fastening the fixing screw is achieved through negative-pressure suction, the
internal pressure can also be monitored through the
pressure sensor in real time, and accordingly whether or not the fixing screw is loosened is judged.
