The multi-functional minor surgery training toolbox consists of the following main functional modules:

 Normal skin module: This module is mainly used to simulate various surgical operations of normal human skin, such as incision, suture, knot, thread cutting, suture removal, etc., which is a key part of the basic training of surgical operation. Through this module, students can master various basic surgical skills and lay the foundation for subsequent more complex surgical operations [1].

Sebaceous cyst excision Exercise module: Sebaceous cyst, also known as powderoma, is a common skin disease. This module simulates the whole process of sebaceous cyst resection, enabling students to perform surgery in a simulated environment, so as to familiarize themselves with and master surgical procedures and techniques [2].

Lipoma excision Exercise module: Lipoma is a subcutaneous mass, common in all parts of the human body. This module simulates the operation process of lipoma resection, and students can conduct operation training on this module to improve their surgical skills [2].

Common skin Lesions Management training module: This module includes a variety of common skin lesions management training, such as skin exfoliation, skin nevus excision, skin seborrheic keratosis curettage, etc. By simulating the management of these lesions, trainees can learn and master surgical techniques and strategies for different lesions [1].

In addition, the multi-functional minor surgery training Kit is also equipped with a rich training guide CD-ROM to provide trainees with detailed surgical instructions and explanations. At the same time, the tool box also contains a set of commonly used small surgical instruments, so that students can better understand and use surgical instruments in actual operation [1][2].

It is worth noting that each functional module can be replaced to suit different teaching and training needs. This design makes the multi-functional minor surgery training toolbox highly flexible and scalable to meet the training needs of different trainees and institutions [1].

To sum up, the multi-functional minor surgery training toolbox includes several major functional modules such as normal skin module, sebaceous cyst excision practice module, lipoma excision practice module and treatment training module for common epidermal lesions, providing students with a comprehensive and systematic surgical operation training platform.
