Description

Technical Field

[0001] This invention relates to the field of medical trauma orthopedic training technology, and in particular to a simplified modular blind orthopedic training model. Background Technology

[0002] Since ancient times, traumatologists have trained by touching and identifying bones from cadavers with their eyes closed, developing their tactile sense and creating a three-dimensional mental model of the skeleton to achieve the ability to understand bones by touch. Because cadaver bones are scarce, this method is difficult to apply widely. Traumatologists mostly train by touching and identifying bones from living patients in clinical practice, requiring a large number of patients to practice bone setting and reduction before developing the ability to diagnose and treat bone injuries by touch.

[0003] Currently, with the production and use of artificial bone simulation models, clinical teaching can utilize artificial bone models, thus popularizing and promoting bone model teaching methods. Most currently designed and produced fracture training models focus on training and testing reduction techniques such as traction, manipulation, and compression. There are no teaching models specifically designed for training manual palpation and tactile feedback skills. Existing training and evaluation devices used in orthopedic clinical teaching are relatively expensive, complex in structure, costly to teach, and inconvenient to carry, hindering daily classroom teaching. Therefore, this paper proposes to design and invent a simple, easy-to-use, relatively inexpensive model that facilitates widespread and convenient daily teaching for training manual palpation and tactile feedback skills, thereby addressing the shortcomings of existing teaching and training devices. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a simplified, modular, blind orthopedic training model.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A simple modular bone setting blind method training model includes a bone model and a blind bag. The bone model has a fracture section. The two bone models on both sides of the fracture section are connected by a connecting cylinder. Multiple elastic rubber strips that mimic the traction of muscles and ligaments are provided between adjacent bone models.

[0007] The blind bag covers the skeleton model, and the inside of the blind bag is lined with a lining. The blind bag also has a side opening with an adhesive strip on the outside.

[0008] Preferably, the skeleton model has multiple fixing holes, and the ends of the elastic rubber strips are connected to the fixing holes.

[0009] Preferably, connecting grooves are provided on both sides of the fractured portion on the bone model.

[0010] Preferably, the connecting groove is a cylindrical cavity, and the connecting cylinder is inserted into two opposite connecting grooves.

[0011] Preferably, the blind bag is cylindrical, and the material of the outer surface is leather or cloth, and the inner lining is sponge or soft rubber.

[0012] Preferably, one side of the side opening is sewn with a sticking part on the outer surface of the blind bag.

[0013] Preferably, one end of the sticking strip is fixed by sewing between the outer surface of the blind bag, and the other end is fixed by magic tape between the sticking part.

[0014] The beneficial effects of the present application are:

[0015] 1. The present application can meet the standardized clinical skill training simulation teaching requirements of the orthopedic department of traditional Chinese medicine colleges and hospitals, is simple to use, has relatively low teaching cost, is easy to obtain materials, can be self-made, is convenient to carry, is beneficial to classroom teaching and skill assessment, is easy to popularize and apply, is beneficial to medical students and resident physicians to quickly learn, understand and master the skills of eight bone setting methods, is beneficial to train students' diagnosis and treatment skills of touching the heart, makes up for the shortcomings of the existing bone setting teaching models, and fills the gap of certain products.

[0016] 2. In actual use, when different difficulty bone touching training is performed, the fractured ends of the simulated bones of the bone model part are connected to form complete bones by the built-in connecting cylinder, are placed in the blind bag, and the trainer touches the bones in the bag through the blind bag to distinguish what human body part the bones are and the anatomical characteristics of the bones. Different thickness of the blind bag can be used for different difficulty training. If examination is needed, the blind bag is opened to check the correctness of the bone touching in the blind bag.

[0017] 3. The assembly of the bone fracture model can enable students to perceptually understand the anatomical morphology of the bones, the fracture types, the attachment points of the muscles attached to the bones, and the recognition of the fracture displacement types caused by the mutual pulling force of the muscles, can simulate the learning of the trauma mechanism of the fracture displacement and the principle of the reverse trauma mechanism reduction, and thus understand and master the eight bone setting methods.
