Description

Technical Field

[0001] The present invention relates to a medical robot, in particular to an automated plaster fixation device, belonging to the technical field of medical equipment. Background Art

[0002] Currently, cast immobilization is performed manually by doctors, but this can present several challenges: 1. Variability in doctor experience can lead to complications during cast immobilization. For example, a cast that is too tight can compromise circulation, potentially leading to distal ischemic necrosis in severe cases; a cast that is too loose can be ineffective. 2. Manual cast application is time-consuming and labor-intensive, requiring significant human resources. Therefore, designing a robotic device that can automate cast immobilization and other procedures holds promise for clinical application. Summary of the Invention

[0038] The connection method between the fixing belt and the functional position recovery plate includes but is not limited to rivet connection, screw connection, Velcro connection, buckle connection, and lacing.
