Abstract
The invention relates to a model for demonstrating growth patterns of uterine fibroid. The model can vividly demonstrate an expansive growth pattern and an exophytic growth pattern of a benign tumor. The technical scheme includes that the model comprises a uterus model and adnexa uteri, a muscular layer of the uterus model and a lower layer of a mucosa are provided with a myoma model which can be inflated and enlarged, the myoma model is respectively connected with a left ovary inflatable model and a right ovary inflatable model, one end of an inflating catheter of uterus round ligament is communicated with the myoma model, the other end of the inflating catheter is communicated with the ovary inflatable models, and a one-way breather valve is arranged in the inflating catheter. The model has the sense of reality, can intimate and demonstrate corresponding symptoms when the benign tumor blocks and compresses surrounding tissues and organs, guides students to find out and think about problems, and enables the medical students to further know about pathological characteristics of the benign tumor.
Description
Technical field
The present invention relates to a kind of teaching aid, particularly fibroid growth pattern demonstrating model.
Background technology
In the pathology teaching, fibroid is the female reproductive system most common tumor.Majority betides mesometrium, and a part is positioned under the mucous membrane or under the serous coat, the myomata growth pattern is expansive growth and exophytic growth; Expansive growth is because tumor cell growth is slow; Along with gross tumor volume increases gradually,, can push, push surrounding tissue open just like the balloon that expands gradually; But betide the submucosal myoma of uterus exophytic growth, fall in uterine cavity or cervical orifice.In existing teaching aid instrument, also there is not a teaching aid can carcinoid growth pattern visual pattern dynamically demonstrated out.The fibroid sample is static the displaying, can not show the process that swelling property, exophytic growth are blocked the compressing of adjacent tissue.Multimedia animation teaching can only be demonstrated indirectly, the dynamic process that the student can not Direct observation illustrative teaching aid.
Summary of the invention
Summary of the invention:
The technical matters that the present invention will solve provides a kind of model of simple in structure, visual pattern demonstration fibroid growth pattern; For solving the problems of the technologies described above; Said fibroid growth pattern demonstrating model; Comprise uterus and annex, said model of uterus flesh layer is interior, submucosa contains the uterus muscle intramural myoma model and the submucosal myoma of uterus model of inflatable increase, and connects aerating device respectively---left ovary inflation model and right ovary inflation model.Left side round ligament of uterus gas-filled tube one end and left ovary inflation model are connected, and the other end and submucosal myoma of uterus model are connected; Right round ligament of uterus gas-filled tube one end and right ovary inflation model are connected, and the other end and uterus muscle intramural myoma model are connected, and are provided with breather cheek valve in the round ligament of uterus inflating catheter.
Obtain the present invention's realization simple in structure, easy according to technique scheme, the present invention can intuitively demonstrate the mode of fibroid expansive growth, exophytic growth, makes the student to carcinoid pathological characteristic understanding further arranged, and has the following advantages:
(1) simulation is realistic;
(2) but corresponding symptom appears in analog demenstration benign tumour resistance cancer compressing surrounding tissue organ, guiding student is pinpointed the problems, is pondered a problem;
(3) simulated operation is repeatable.

Embodiment:
Be technological means, the creative feature that the present invention is realized, the consistance with effect of achieving the goal is below in conjunction with further proof the present invention of concrete demonstration.
It is the female reproductive system most common tumor that hysteroma becomes.Majority betides mesometrium, and a part is positioned under the mucous membrane or under the serous coat, the myomata growth pattern is expansive growth and exophytic growth; Expansive growth is because tumor cell growth is slow; Along with gross tumor volume increases gradually,, can push the extruding surrounding tissue open just like the balloon that expands gradually; But betide the submucosal myoma of uterus exophytic growth, fall in uterine cavity or cervical orifice.
Based on above-mentioned principle; Existing with reference to accompanying drawing 1; Explain as follows in conjunction with embodiment: fibroid growth pattern demonstrating model of the present invention; Comprise model of uterus 1 and annex 2, in said model of uterus flesh layer 3 with in the submucosa 4, be respectively arranged with the uterus muscle intramural myoma model 5 and submucosal myoma of uterus model 6 of inflatable increase, and connect aerating device respectively---left ovary inflation model 7 and right ovary inflation model 8.Left side round ligament of uterus gas-filled tube 9 one ends and left ovary inflation model 7 are connected, and the other end and submucosal myoma of uterus model 6 are connected, and are provided with breather cheek valve 11 in the inflating catheter; Right round ligament of uterus gas-filled tube 10 1 ends and right ovary inflation model 8 are connected, and the other end and uterus muscle intramural myoma model 5 are connected, and are provided with breather cheek valve 11 in the inflating catheter.
Utilize uterus 1 and annex 2 design demonstration fibroid expansive growths, exophytic growth mode, the ovary model is set to inflatable ball, and round ligament of uterus is set to inflating catheter, and fibroid is set to inflatable and increases, and makes demonstration more true to nature, vivid.
According to the exemplary model of technique scheme, concrete presentation process is following:
During use; At first push right ovary inflatable ball model 8 gases through in the uterus muscle intramural myoma 5 in the 11 entering mesometriums 3 of the breather cheek valve in the right side round ligament of uterus gas-filled tube 10; Myomata is because of inflate the increase of expanding gradually; Surrounding tissue is squeezed and simulates fibroid expansive growth mode, myomata because of inflation gradually outwards expansion can make uterine cavity distortion, hyper-menorrhea or infertile etc.
Pushing left ovary inflatable ball model 7 gases then gets in the submucosal myoma of uterus 6 of uterine mucosa lower floor 4 through the breather cheek valve in the left side round ligament of uterus gas-filled tube 9 11; Myomata is because of inflate the increase of expanding gradually; Surrounding tissue is squeezed and simulates fibroid exophytic growth mode; Fleshy polyp is because of inflation is outwards outstanding gradually, and myomata can influence menses discharge generation dysmenorrhoea and with hyper-menorrhea, fall in uterine cavity or cervical orifice and can cause infertile.
Claims (2)
1. fibroid growth pattern demonstrating model; Comprise model of uterus and annex; It is characterized in that: uterus muscle intramural myoma model and submucosal myoma of uterus model that inflatable increase is arranged respectively with submucosa in the said model of uterus flesh layer; Said uterus muscle intramural myoma model is connected aerating device respectively with the submucosal myoma of uterus model---left and right sides ovary inflation model; Left side round ligament of uterus gas-filled tube one end and left ovary inflation model are connected, and the other end and submucosal myoma of uterus model are connected, and are provided with retaining valve in the inflating catheter; Right round ligament of uterus gas-filled tube one end and right ovary inflation model are connected, and the other end and uterus muscle intramural myoma model are connected.
2. according to claim 1, described fibroid growth pattern demonstrating model is characterized in that, is provided with breather cheek valve in the said round ligament of uterus inflating catheter.
