Description

A training model for surgical knotting and suturing

technical field

The invention relates to a medical teaching appliance, in particular to a training model for knotting and suturing in operations.

Background technique

The country and medical colleges and universities have paid more and more attention to the teaching of clinical skills year by year, and have continuously increased the investment in the construction of clinical skills in medical colleges and universities. The teaching of clinical skills, especially the teaching of basic surgical skills, has developed rapidly. We have found a problem in the course of many years of surgical skills teaching: although the hardware strength of medical schools has been strengthened, the effect of students learning surgical skills and the clinical work of young doctors have not been significantly improved.

Through the communication with medical students and clinical surgeons, it is found that the main reason for the poor learning effect of students is the lack of surgical skills practice. Due to the increase in the number of medical students year by year, the limited resources of medical schools cannot meet the training needs of medical students. In the past, a medical school trained very few medical students, which belonged to elite education. Most of the training for surgical knotting and suturing skills was performed on experimental animals. use. Now some medical schools enroll thousands of students in medical related majors a year. The original training methods can no longer adapt to the current teaching environment. Only through model training can the quality of students' learning be improved. Due to the current medical environment, it is impossible for young clinical surgeons to practice basic operations on patients, and the training models can be purchased, which is expensive and requires a huge investment in consumables in the later stage. These problems directly affect the quality and effect of surgery. There are few manufacturers of surgical knotting and suturing training models, with poor selection and high prices. It will be a huge investment to achieve one model training for each medical student. In order to cope with the growing demand for teaching and training, it is determined that the model should be multifunctional, miniaturized, simplified, and practical.
