Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a uterus prolapse teaching mould. BACKGROUND

[0002] The uterus is located in the middle of the pelvis, and the bladder is in front of it, the rectum is behind it, the vagina is below it, the bottom of the pelvis has tough muscles and fascia support, the uterus is connected to the pelvic wall by ligaments on both sides and behind it, so that the uterus is slightly forward flexion when standing, therefore, even when abdominal pressure is increased, the external cervical os is still above the ischial spine level, and the uterus will not prolapse in the direction of the vagina, but when the pelvic floor muscles and uterine ligaments are torn due to injury, or other reasons cause the tension to decrease, the supporting function of the pelvic floor is weakened, the uterus may prolapse, that is, the uterus descends from its normal position along the vagina, and in severe cases, it can protrude outside the vaginal opening, at present, the learning of uterine prolapse is mainly through text, video and picture analysis, but students cannot easily establish a three-dimensional impression through text, video and pictures, so they cannot fully understand and remember the knowledge related to uterine prolapse, and the teaching quality cannot be guaranteed. SUMMARY

[0003] The utility model solves the technical problem that, in view of the above-mentioned defects, provide a kind of uterus prolapse teaching mould, not only can the different prolapse of uterus degree be more clearly demonstrated, guarantee teaching quality, and it is convenient to be stored when not being used.

[0004] The utility model solves its technical problem and adopts the technical scheme: a uterus prolapse teaching mould, including pelvic cavity organ model, the pelvic cavity organ model includes vaginal anterior wall, vaginal posterior wall and uterus, the pelvic cavity organ model is divided into first model and second model along vertical direction, the first model and second model can rotate relative, the vaginal anterior wall and vaginal posterior wall are located in the side of first model and second model and are close to each other, and the first model and second model are arranged in the initial state and are close to each other, the uterus is located between the passageway formed by vaginal anterior wall and vaginal posterior wall and can move along the passageway, and the vaginal anterior wall and vaginal posterior wall are equipped with scale line for showing the prolapse degree of uterus.

[0005] Compared with the prior art, the working principle and beneficial effects of the present scheme are that: when teaching demonstration is not needed, i.e. in the initial state, the first model and the second model are arranged in parallel, i.e. the anterior vaginal wall and the posterior vaginal wall are arranged in parallel, so that the whole uterine prolapse teaching mold can be conveniently stored; when teaching demonstration is needed, the two mounting seats are rotated in the direction away from each other, so that the anterior vaginal wall and the posterior vaginal wall are separated and the uterus located between the two is exposed, after being opened, the uterus is located in the half-channel of the anterior vaginal wall or the posterior vaginal wall, the uterus is moved along the channel and is sequentially moved to different scale lines, so that different uterine prolapse degrees are demonstrated, and the different uterine prolapse degrees can be clearly demonstrated through the scale lines arranged on the anterior vaginal wall and the posterior vaginal wall, thereby achieving better teaching effect.

[0006] As a preferred embodiment of the present application, the anterior vaginal wall and the posterior vaginal wall are both made of elastic material, and the channel located between the two has elasticity.

[0007] Explanation: The upper end of the uterus is wide and is called the fundus, which is the uppermost part of the uterus; the lower end of the uterus is narrow and is called the cervix, which connects the uterine body and the vagina, and the overall shape of the uterus is similar to an inverted pear shape.

[0008] The beneficial effect of the present scheme is that: the fundus is wide and the cervix is relatively narrow, if the channel is too small, the fundus cannot be moved forward along the channel, and if the channel is too large, the uterus cannot be fixed after being moved along the channel, and a limiting structure needs to be additionally arranged, therefore, the channel with elasticity can adapt to the shape of the uterus and cannot be moved along the channel or cannot be fixed after being moved.

[0009] As a preferred embodiment of the present application, the scale lines are located on the upper part of the channel.

[0010] The beneficial effect of the present scheme is that: since half of the uterus is located in the channel on one side and the other half is suspended when the anterior vaginal wall and the posterior vaginal wall are separated, compared with arranging the scale lines on the lower part of the channel, arranging the scale lines on the upper part of the channel can avoid that the half of the uterus which is suspended covers the scale lines on the lower part of the channel during the movement of the uterus, thereby avoiding affecting the demonstration effect.

[0011] As a preferred embodiment of the present application, the two ends of the uterus are both provided with ropes.

[0012] The beneficial effect of the present scheme is that: when the uterus needs to be moved along the channel for demonstration of uterine prolapse, the position of the uterus in the channel is adjusted by pulling the rope at the front end of the uterus, which corresponds to the scale lines one by one, and after the demonstration is completed, the uterus can be moved into the channel by pulling the rope at the rear end of the uterus, which is convenient to operate.

[0013] In a preferred embodiment of the present invention, the first model and the second model are respectively mounted on a first mounting base and a second mounting base that can rotate relative to each other. The upper front part of the first mounting base and the lower front part of the second mounting base are respectively provided with an L-shaped first connecting block and a second connecting block. Both the first connecting block and the second connecting block are provided with connecting holes for the locking member to pass through.

[0014] The beneficial effects of this solution are: by setting both the first connecting block and the second connecting block to an L-shape, it can be ensured that the first model and the second model can be rotated to a closed state when the uterine prolapse teaching mold is not used, and will not be blocked by the rotational connection of the first connecting block and the second connecting block.
