Negative-pressure fastening correction-type skull traction device capable of being intelligently regulated and controlled

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an intelligently adjustable negative pressure fastening and correction type skull traction device. Background technique [0002] At present, people and animals in the world are treated with traction for cervical instability injuries (cervical fractures, dislocations, odontoid process fractures, atlantoaxial dislocations, cervical dislocations with interlocking articular processes, etc.) and the resulting pathological conditions , Most of them follow the skull traction method. Cranial traction is a necessary measure for the early treatment of cervical trauma, and the cranial traction device needs to be used for continuous traction of the skull during treatment. The structure of the traditional skull traction bow is similar to a clamp-type bow. The main body of the clamp-type bow is two hinged arc-shaped clamping rods. The clamping parts of the clamping rods ar...

Problems solved by technology

[0004] Although the cranial traction and fixation has been carried out for many years with the external fixator of the clip-type bow body, the whole traction course takes a long time, and this process is more painful for the patient. Tends to loosen during activity, which can leave the patient vulnerable to needle tract infections, anorexia, depression, cartilage damage, and other side effects that delay recovery
