Description
Technical Field
The invention relates to the technical field of auxiliary exercise models, in particular to a 3D printing-based parotid palpation model.
Background
Visual touch percussion and auscultation are basic physical examination skills necessary for clinicians, and due to the characteristics of the tissue structure of the maxillofacial region, percussion and auscultation are very limited, so that visual touch and palpation play an important role in obtaining the impression of diagnosis of pathological changes of the maxillofacial region, and judging the types and development stages of diseases. In the medical teaching activities, the medical students reappear the visual diagnosis scenes through high-definition pictures and demonstration documents, so that the main points of the visual diagnosis can be rapidly mastered. Palpation requires touching and pressing the tissues and organs of a patient, and determines the position, size, shape, hardness, boundary and activity of a lesion according to hand tactile feedback, which is always a key and difficult point in the body examination teaching of the department of maxillofacial surgery. Especially for parotid diseases, the lesion positions are deep, and the visual diagnosis has almost no specific difference, so that the palpation plays a crucial role in the clinical preliminary diagnosis of the diseases. The traditional palpation teaching has the following disadvantages: 1. the lesion area and the healthy tissue of the patient need to be touched and pressed repeatedly in the early stage of palpation exercise, so that the patient feels the characteristics of the lesion and is uncomfortable. 2. The privacy and right-maintaining consciousness of the patient are gradually improved and matured, and medical students can reduce the number of exercise cases. 3. The number of medical students is increased, the practice classmates of a single patient are gradually increased, and the discomfort and the pain of the patient are further aggravated. 4. There are many kinds of parotid diseases, and even the same kind of diseases have large component variation, and palpation shows a difference, which sometimes results in the lack of typical patients.
