Fracture manipulation reduction training device, and preparation method and training method thereof

Abstract

The invention provides a fracture manipulation reduction training device, and a preparation method and a training method thereof. The fracture manipulation reduction training device sequentially comprises a skin tissue component, a subcutaneous tissue component and a bone tissue component from outside to inside. The bone tissue component comprises a first bone tissue unit, a second bone tissue unit, at least two elastic bands and a universal hinge component. The first bone tissue unit is provided with a first fracture broken end, the second bone tissue unit is provided with a second fracture broken end, the first fracture broken end and the second fracture broken end are matched with the fracture end of a patient, and the first bone tissue unit is connected with the second bone tissue unitthrough the universal hinge component and the elastic bands. Various complex fracture end forms of various fracture parts in clinic can be truly restored, clinical teaching, training and evaluation are facilitated, and the restoration technology of young doctors is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of fracture reduction, and in particular relates to a fracture manipulation reduction training device, a preparation method and a training method. Background technique [0002] Fracture is one of the most common diseases in orthopedic clinic, accounting for about 16% of all musculoskeletal system injuries. Fracture reduction and fixation are the key to fracture treatment. Manipulative reduction refers to the reduction of the fracture end by the doctor with bare hands, which is an effective method for fracture reduction. Good manual reduction and external fixation have the advantages of less trauma and less pain, and can effectively promote fracture healing. Improper manual reduction and fixation can easily lead to damage to the fracture end, soft tissue, blood vessels, and nerves, resulting in complications such as fracture redisplacement, which seriously affects fracture healing. Therefore, it is of grea...

AI Technical Summary

Problems solved by technology

However, the existing simulation devices for manipulative reduction and fixation training are insufficient, and have the following defects: 1) Most of them are simple transverse fractures, and it is difficult to truly restore the fracture ends with different shapes in clinical practice; 2) There are few fractures for training, and it is difficult to Meet the clinical requirements; 3) The mechanical properties of the simulated bone are single, unable to simulate the bone status of patients of different ages and different basic disease states; 4) It is difficult to systematically evaluate the fracture reduction, especially after fixation, it is difficult to determine whether the fracture has redisplaced, Unable to evaluate the training effectiveness of young physicians
