Construction method of forearm curved surface model and forearm fixing brace

The invention discloses a forearm curved surface model construction method and forearm fixing brace. The forearm curved surface model construction method comprises the following steps: S1, carrying out data collection from elbow parts of forearms of a plurality of human bodies to finger ends of four fingers outside the thumb to obtain corresponding forearm data models; S2, the forearm curved surface model construction method comprises: S2, for each forearm data model, intercepting a characteristic plane of the forearm data model to obtain forearm characteristic curves, and obtaining a plurality of corresponding forearm characteristic curves; 3, aligning a plurality of forearm characteristic curves at a preset position, obtain an average value of that plurality of forearm characteristic curves, and obtaining an average forearm characteristic curve; S4: Constructing a standard forearm surface model according to the average forearm characteristic curve. The forearm surface model constructed by the forearm surfac
