Interactive virtual fractional curettage teaching system and method

Abstract

The invention discloses an interactive virtual fractional curettage teaching system and method. The interactive virtual fractional curettage teaching system comprises an integrated shell, a simulating curettage spoon, a two-dimensional motion positioning system, a universal component, a data information processor and a displayer. All the components are arranged in the integrated shell. The simulating curettage spoon is inserted in the universal component. The universal component has sensory and tactile feedback and is clamped in the front center of the integrated shell. The data information processor is fixed to the two-dimensional motion positioning system and used for establishing a virtual environment and user interaction. The simulating curettage spoon has three rotational degrees of freedom and one displacement degree of freedom and is used for simulating fractional curettage operation. According to the technical scheme, a simulative surgery operation simulating device and the teaching method are provided for a teacher and learners, the function of real-time curettage spoon pressure calculation is achieved, the operation strength can be sensitively captured, timely tactile feedback can be provided, visual learning can be achieved, and learning efficiency can be improved.

Description

technical field [0001] The invention relates to the field of medical teaching, in particular to an interactive virtual segmental curettage teaching system and teaching method. Background technique [0002] Segmental diagnostic segmental curettage (referred to as segmental curettage) is one of the clinical skills that all clinical medicine students must master, and it has strong clinical practicability. The teaching work of traditional segmental curettage relies on rubber molds to complete. The instructor can only guess the operation of the students through the operation steps of the students and the exposed part of the curettage instrument, and then conduct assessment and guidance, which not only increases the difficulty of teaching, reduces the efficiency of teaching, but also makes it impossible for students to know whether their operation is correct and how strong they are. Is it appropriate. Therefore, the existing teaching equipment and teaching methods make students ...

AI Technical Summary

Problems solved by technology

The instructor can only guess the operation of the students through the operation steps of the students and the exposed part of the curettage device, and then conduct assessment and guidance, which not only increases the difficulty of teaching, reduces the efficiency of teaching, but also makes it impossible for students to know whether their operation is correct and how strong they are. Is it appropriate

Therefore, the existing teaching equipment and teaching methods make students encounter two problems after entering clinical practice. On the one hand, they cannot accurately implement segmental curettage, which confuses cervical or uterine cavity specimens, which brings difficulties to clinical diagnosis; On the one hand, the strength is not appropriate. In mild cases, it will cause strong discomfort to the patient. In severe cases, it will cause medical accidents such as endometrial damage and uterine perforation, which will bring trauma to the patient's body and mind, and the expected effect of clinical teaching cannot be achieved.
