Abstract
A verification method of an osteotomy guide tool, a verification system and a detection element are disclosed. The verification method includes obtaining a pose parameter of a feature portion of an osteotomy guide tool in a coordinate system of a trackable element; then comparing the obtained pose parameter of the feature portion of the osteotomy guide tool with a corresponding standard value to obtain an offset between the pose parameter of the feature portion of the osteotomy guide tool and the standard value; if the offset is greater than an expected value, the osteotomy guide tool is determined as deformed. With this configuration, the osteotomy guide tool can be verified to avoid deformation of the osteotomy guide tool during repeated use or transportation, affecting its positioning accuracy and affecting the operation.
