Medical model for cervical cerclage simulation teaching

Abstract

The invention belongs to the technical field of medical teaching models, and relates to a medical model for cervical cerclage simulation teaching, which comprises a base module, an assembly module anda cervix model module; the base module is a model from the waist and abdomen to the thighs of a human body and is internally provided with a cavity structure; an open groove is formed in the externalgenital organ part, is communicated with the cavity structure and is connected with the assembly module in a matched manner; the assembly module is provided with a vaginal orifice and a vaginal modelwith a connector; a connecting bolt is arranged on the cervix model module, and the cervix model module is detachably connected with the vaginal model; the cervix can be placed in the vaginal model and can also be exposed at the vaginal orifice, and the assembly module and the cervix model module are both made of high-elasticity materials. The medical model has the advantages that the simulationdegree is high, the cervix can be placed at the port in the vagina and exposed to the vaginal orifice, the clinical environment can be simulated, a beginner can be supported to learn from low difficulty, the assembly is detachable, and different cervix form assemblies or damaged assemblies can be replaced.

Description

technical field [0001] The invention relates to the technical field of medical teaching models, in particular to a medical model for simulating teaching of cervical cerclage. Background technique [0002] The incidence rate of premature birth in my country is about 7-8%, and about 1.17 million premature babies are born every year. Preterm babies have many complications and high mortality. The prevention of premature birth is the focus of clinical work in obstetrics. About two-thirds of premature births are spontaneous premature births. Cervical cerclage is a surgical treatment to prevent spontaneous premature births. However, due to the relative lack of opportunities for clinical operations, this surgical technique has not widely used by obstetricians. Medical simulation training is an effective method for efficient training. In order to achieve better training results, a teaching model of cervical cerclage that is both highly realistic and easy to display is required. At ...

AI Technical Summary

Problems solved by technology

At present, there is no medical model specially used for cervical cerclage in China, and the medical cervical model used for gynecological examination has many limitations, such as the poor elasticity of the vagina material, which cannot meet the needs of cervical cerclage to fully expand the vagina and expose the cervical anatomy The cervix cannot be pulled out of the vaginal opening. It is difficult for beginners to operate, and it is not convenient for teaching and display. The cervix has a single shape and is inconvenient to replace. It cannot simulate different cervix shapes and clinical conditions.

[0003] Chinese patent document: CN108597337A discloses a kind of embryo transfer model and teaching method, the present invention according to the ratio of normal female reproductive system, the length, width, thickness, volume, diameter of each part of the model (uterine body cavity, cervix, vagina) The specific quantitative design, combined with the length of the internal and external catheters for transplantation, enables embryo experimenters and clinicians to have a more intuitive and accurate understanding of the relative distance and space of the transplantation path, so as to have better control over the embryo transfer position, enabling clinical Physicians can fully experience several key difficulties in the transplantation path, and through repeated practice, they can overcome the difficulties in the formal transplantation operation and achieve smooth intubation, that is, this patent document provides a model of embryo transfer and a teaching method for embryo transfer , it mainly solves the problem of embryo transfer teaching, and its model emphasizes specific quantitative design to train students to grasp the distance and position of embryo transfer operation; but it does not solve the above technical problems, and cannot achieve efficient cervical cerclage surgery Teaching function

The advantage of this patent document is that the expansion of the cervix is ​​made into the form of inserts, and multiple slots can simulate various states of cervix expansion. During the palpation process, students can feel real and can fully experience a part of the prenatal cervix. The series of changes can be used for teaching demonstrations and practical exercises, but it does not solve the above technical problems, nor can it realize the efficient teaching function of cervical cerclage surgery, and the technical solution in this patent document is not realistic enough to meet the teaching of simulated clinical operations need
