An Intelligently Adjustable Negative Pressure Fastening Corrective Skull Traction Device

Abstract

The invention discloses an intelligently regulated negative pressure fastening and correction type skull traction device. Including the central connection part, traction bow, connector, negative pressure generator, fixing screws, fixed pads, the central connection part includes a cylindrical shell, MCU chip, connection interface, built-in wifi module, battery, and the connector is located above the central connection part , the negative pressure generator is connected to the outside of the connector, the upper end of the traction bow is connected to the connection interface respectively, the fixed pad is connected to the lower end of the traction bow, a pressure sensor is arranged inside the fixed pad, the fixing screw runs through the fixed pad horizontally, and the fixing screw The interior is hollow, and the side wall is provided with a suction hole and connected to the connector through a hose. The present invention achieves the purpose of fastening the fixing screws through negative pressure suction, and can also monitor the internal pressure through a pressure sensor to judge whether the fixing screws are loose.

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
