Description

Technical Field

[0001] The utility model belongs to the technical field of medical training teaching aids, and in particular relates to a training teaching aid for maxillofacial local skin flap marking transplantation. Background Art

[0002] Oral and maxillofacial regions often suffer from tissue defects due to trauma, deformity, tumors, and other reasons. Currently, large complex tissue defects are mostly treated with free flaps for labeling and transplantation, while common small and medium defects are treated with pedicled tissue flaps for labeling and transplantation. This type of flap labeling is a transfer of adjacent tissues, with less trauma and better results. However, there are many types of oral and maxillofacial local pedicled tissue flap labeling and transplantation. Different types of local flap labeling and transplantation are suitable for different defects, which is difficult to learn.
