| Summary: | 碩士 === 國立高雄第一科技大學 === 機械與自動化工程所 === 96 === The primary use of traction by a physical therapy is to decompress the distance between bone sections of the vertebra in order to alleviate pressure on nerves. The traction can provide precise and modulated pull strength to ease pain and discomfort of the human body created by long term tension; therefore, the traction is widely applied in clinical treatment as well as research. The domestic development of traction devices has produced similar devices under strain of cost-benefit limitations. The purpose of this study is based on how one can provide a safe and effective traction output pull that is clinically effective and lucrative.
This study uses the Dynamic Taguchi Method to determine the traction’s output pull stability, along with the use of Parallel Motion Mechanism to improve the traction’s output pull precision. Experimental results confirm that the output pull strength can be controlled within the commonly used range for cervical vertebra (below 20 kg) target value of ±0.5 kg and for lumbar vertebra (below 40 kg) target value of ±1.0 kg. These results substantiate the improvements and effective safety of the traction output.
The conclusion of this study supports the safety in the clinical use of traction in treatment of the vertebra and further provides an objective evaluation of the traction’s clinical efficacy for reference. The successful application of methods in design and improvement may be transferred for usage in the medical industry as a tool to improve quality and to reduce cost in the development of a quality traction device.
