颈椎牵引复位装置与颈椎牵引复位系统
By combining a multi-bar drive mechanism and an arc-shaped guide rail, along with a controller and a magnetic navigation sensor, a wide range of posture adjustments for cervical spine fractures and dislocations is achieved. This solves the problems of inconvenient adjustment in three-dimensional space and large structure of existing devices, and improves the safety and success rate of repositioning.

AI Technical Summary
Existing traction reduction devices for cervical spine fractures and dislocations suffer from inconvenience in three-dimensional spatial adjustment and are structurally bulky, making it difficult to achieve a wide range of adjustments to the cervical spine's posture.
The system employs a combination of a multi-bar drive mechanism and an arc-shaped guide rail mechanism. The multi-bar drive mechanism is connected in parallel through multiple telescopic drive components, which, combined with the sliding component of the arc-shaped guide rail, enables multi-degree-of-freedom adjustment of the cervical spine. The controller generates traction parameters and paths, and coordinates with the magnetic navigation sensor for real-time adjustment.
It enables a wide range of cervical spine posture adjustments, has a compact structure, and can precisely control traction force and path, reducing the risk of secondary injury and improving the success rate and safety of repositioning.
