System capable of enabling difference realignment to be carried out on spinal column under tensile force

Abstract

A system for differential realignment of vertebra under tension is provided. It provides a tensioning device (10) including a patient-positioning means (100), a tension-producing actuator (170), a positioning device (140), a patient interface device (120) and a control system (190). The control system (190) with feedback on the resultant tension vector applied to patient spine allows for adjustment of either tension producing actuator (170) position or patient position or both while applying therapeutic tension levels to the patient spine. The tensioning device (10) automatically adjusts the resultant tension vector angle such that the resultant tension vector magnitude remains ideally constant during the adjustment of the tension producing actuator (170) position or the patient position, facilitating flexion of spinal segments while reducing the risk of eliciting paraspinal muscle contraction due to changes in resultant tension vector magnitude.

Description

technical field [0001] The present invention relates to a system for applying tension to a patient's spine to treat spinal disorders. In particular, the present invention relates to a system for differential realignment (DRV) of a specific spine by oscillating the treatment angle under tension during treatment without changing the desired tension, the purpose of which is to further relax the paravertebral muscles of the spine, Increase disc retraction and stimulate articular cartilage (eg, facet articular cartilage) as a means to promote the benefits of continuous passive motion (CPM). Background technique [0002] Physiotherapists use spinal decompression therapy to treat a variety of spinal conditions, including herniated discs, degenerative disc disease, sciatica, posterior facet syndrome, and post-surgical pain. Decompression therapy derives from traditional traction-based therapy, which places the spine in tension by an external force (eg, the hands of a physical thera...

AI Technical Summary

Problems solved by technology

[0011] However, the current traction or decompression program, even through the comprehensive system positioning calculation results, patient position and feedback information from the patient, can finally determine the correct treatment angle for this particular patient, so that the decompression force can be applied at a relatively precise angle. at the lesion position, but this angle setting is fixed

In the specific treatment, there may still be slight deviations, and if such slight deviations are not corrected, patients will not be able to get the best treatment effect

In addition, since the force application angle is fixed, various curve fluctuations cannot be performed within a fine range, and continuous passive motion (CPM) of vertebral facet joints cannot be achieved while reducing pressure.
