Long bone fracture traction reduction navigation apparatus

Abstract

The invention discloses a fracture traction reduction guiding device of a long bone. The device comprises a driving mechanical arm, a driven mechanical arm, a photoelectric tracer, an end effector, a trolley, a tracking mark component and a spatial point acquisition unit. The tracking mark component is installed on the fracture position of the long bone. The spatial point acquisition unit is held by a doctor. A prop A of the driving mechanical arm and a prop B of the driven mechanical arm are installed on the upper panel of the shell of the trolley respectively. The photoelectric tracer is installed on the end cover of a rocker A of the driving mechanical arm. The end effector is installed on the end cover of a rocker B of the driven mechanical arm. A computer system is arranged in the wagon box of the trolley. The driving mechanical arm has the same structure with the driven mechanical arm. The fracture traction resetting guiding device of the long bone can assist the doctor to finish the reduction operation of 3D geometry of a wounded limb and the mechanical arm is used for fixing the distant end of the wounded limb to improve the accuracy of reduction and to reduce the radiation of X-ray. The tracking mark component is arranged on the fractured bone that needs to be operated, so the position of a characteristic point marked by the tracking mark component is easier to be tracked by the photoelectric tracer.

AI Technical Summary

Benefits of technology

This technology helps reduce pain caused by broken or damaged parts of longer bones called femurs when they heal from injury. It uses an optically tracked camera that captures data about these areas while still being able to see them clearly through lenses attached to cameras. These imaging techniques help medical professionals accurately locate where their damage has been located without exposing themselves to harmful rays like x-rays.

Problems solved by technology

Technics: In this type of treatment for long bony fracture patients, reducing tension with external devices can help reduce pain or improve healing outcomes by allowing the patient's body to move back into its normal position before being fixed permanently. However, current methods are limited because they require multiple x- ray exposing sessions at different locations on the subject's skin surface while also requiring manual adjustment steps from outside the procedure itself due to lack of accurate 3 - dimensional measurement tools.
