Problems solved by technology

[0003] At present, the method for minimally invasive surgery training for doctors is mainly to use virtual simulator training composed of 3D animation and force feedback system. Although 3D simulator is relatively convenient, human tissue is a complex multi-layer material, and its nature depends on Due to the number of layers, the thickness of layers, the direction of muscle fibers, humidity, temperature, etc., the tactile feel of 3D simulation has not been able to meet clinical needs
Therefore, the training effect of the existing above-mentioned minimally invasive surgery training device is not ideal

Abstract

The invention provides an organ model body, a preparation method and application thereof in preparation of a resectoscope resection training model, and relates to the technical field of medical teaching molds. The organ model body comprises a simulated organ cavity and a simulated organ pipeline, wherein one end of the simulated organ pipeline is connected with a closed passage of the simulated organ cavity, and meanwhile, the simulated organ cavity is mainly prepared from the heart of a livestock animal, so that the operation touch feeling and the force feedback of a doctor in minimally invasive surgery training are ensured, and the effect that a training scene is more real is achieved; moreover, the livestock animal heart serving as an in vitro animal organ has the advantages of being convenient to obtain, economical and practical. Therefore, the organ model body not only saves investment of places, cost, labor and the like, but also can routinize minimally invasive surgery training,ensures that doctors can perform repeated training for many times, and achieves sufficient skill proficiency.

Description

technical field [0001] The invention relates to the technical field of medical teaching moulds, in particular to an organ model body, a preparation method thereof and an application thereof in preparing a resectoscope resection training model. Background technique [0002] With the rapid development of contemporary science and technology, medical technology is changing with each passing day, and public health protection has been strengthened in recent years. Documents issued by various competent departments have emphasized the importance of education and training for medical quality. , The teaching mode of "using skills to practice" has led to a serious shortage of opportunities for doctors to practice. Only by changing the traditional mode of training skills on patients can we provide doctors with sufficient opportunities to accumulate skills and reduce the risk of practicing medicine. Surgery has extremely high requirements for doctors' operational proficiency. If doctors ...
