Abstract

The invention discloses a personalized lightweight medical splint and a design method thereof, and relates to the field of medical splints. It includes the following steps: Step 1: constructing a model of the affected limb through three-dimensional scanning; Step 2: determining the design domain of the splint; Step 3: performing biomechanical analysis on the splint and the affected limb to construct a biomechanical model; 4: Designing the porous lightweight splint by using the generative design method; Step 5: Manufacturing the splint by adding materials; Step 6: Monitoring and improving the performance of the splint. The personalized lightweight medical splint disclosed by the present invention not only has the advantages of light weight and good air permeability, but also can realize personalized splint design, precise fixation and regulation of the splint according to the individual differences of patients, thereby improving the treatment effect of bone injuries .

Description

technical field [0001] The invention relates to the field of medical splints, in particular to a personalized lightweight medical splint and a design method thereof. Background technique [0002] In hospital fracture treatment, the most important link and basic method is splinting treatment based on biomechanics. This non-surgical method using fixed structure auxiliary treatment will be adopted as the mainstream treatment method for a long time. The current splints for fracture rehabilitation mainly include plaster splints and small traction splints. In 1982, according to the "static" and "dynamic" balance principles, Shang Tianyu and others composed a local external fixation mechanical system with cloth belts, splints, paper pads, traction and other devices to maintain the reduction of the fracture end and stimulate the compressive stress. In 2004, Wang Yajun and Zhao Jiyin invented the automatic detection small splint. The "Medical Automatic Detection Small Splint" deve...
