Technical Field

[0001] The utility model relates to the technical field of teaching tools, in particular to an abnormal developmental uterus model component for teaching. Background Art

[0002] Uterine malformation is the most common type of reproductive malformation and is of considerable clinical significance. During the evolution of the bilateral mesonephric ducts, influenced and disrupted by certain factors, development may cease at different stages, resulting in various uterine malformations. Some patients with uterine malformations may experience no symptoms, with no abnormalities in menstruation, sexual intercourse, pregnancy, or childbirth, leading to their condition remaining undetected throughout their lives or only occasionally discovered during physical examinations. However, in some patients, reproductive system function is affected to varying degrees, and symptoms are not discovered until sexual maturity, after marriage, or during pregnancy or childbirth.

[0003] There are many forms of uterine developmental abnormalities, such as double uterus and double vagina, double uterus and single vagina, unicornuate uterus and rudimentary horn uterus, etc. Students are easily confused during the learning process, and it is difficult for teachers to have a deep memory in students by teaching through flat diagrams in books.

[0004] Based on the above problems, the present invention proposes a uterine dysplasia model assembly for teaching. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model is further described below:

[0027] See also Figure 1-7 ,

[0028] The utility model discloses a model assembly of an abnormal developmental uterus for teaching, comprising a left unicornuate uterus model 1 and a right unicornuate uterus model 2. The left unicornuate uterus model 1 comprises a left vaginal part 11, a left uterine part 12 and a left fallopian tube part 13. The left vaginal part 11 is a square structure, and its front wall forms a square vaginal groove 15; the left uterine part 12 is an L-shaped structure, the bottom of which is connected to the top of the left vaginal part 11, the left end of the left uterine part 12 is connected to the right end of the left fallopian tube part 13, the front wall of the left uterine part 12 forms a uterine groove 16, the bottom of the uterine groove 16 forms a cervical canal groove 17 for communicating with the top of the vaginal groove 15; the middle part of the front wall of the left fallopian tube part 13 forms a slender fallopian tube groove 18, and the left fallopian tube part 13 has a uterine groove 16 formed therein. The right end of the fallopian tube groove 18 is connected to the left end of the uterine groove 16; the right unicornuate uterus model 2 is mirror-imaged to the left unicornuate uterus model 1, and the right side wall of the left unicornuate uterus model 1 and the left side wall of the right unicornuate uterus model 2 can be connected by a connecting mechanism 3. In this case, the left vaginal part 11, the left uterine part 12, the left fallopian tube part 13 and the ovarian part 14 are provided on the left unicornuate uterus model 1, so that teachers can introduce the various structures of the uterus during teaching. The left unicornuate uterus model 1 or the right unicornuate uterus model 2 can be taken out separately to form a unicornuate uterus form in uterine abnormal development; the right side wall of the left unicornuate uterus model 1 and the left side wall of the right unicornuate uterus model 2 can be connected by a connecting mechanism 3 to form a double uterus and double vagina form in uterine abnormal development.

[0029] Furthermore, a cylindrical ovarian ligament 19 is connected to the bottom of the left end of the transverse section of the left uterine part 12, and the outer end of the ovarian ligament 19 is connected to the right end of the ovarian part 14, and the left end of the ovarian part 14 is connected to the right inner wall of the left fallopian tube part 13. By connecting one end of the ovarian part 14 to the ovarian ligament 19 and the other end to the right inner wall of the left fallopian tube part 13, the model of the ovarian part 14 is more stable, avoiding the problem of easy breakage during teaching use when only the ovarian ligament 19 is used for connection.

[0030] Furthermore, the connecting mechanism 3 includes a limiting rod 31, a connecting groove 32 and an insertion groove 33. The limiting rod 31 is in an L-shaped structure, and its right end is fixed on the left side wall of the right unicornuate uterus model 2. The height of the limiting rod 31 is smaller than the connecting groove 32 and is in a square structure and is arranged on the right side wall of the left unicornuate uterus model 1. The bottom inner end of the connecting groove 32 is provided with the insertion groove 33 for inserting the bottom end of the limiting rod 31. When the left unicornuate uterus model 1 and the right unicornuate uterus model 2 need to be connected, the limiting rod 31 on the right unicornuate uterus model 2 is inserted into the connecting groove 32 on the right side wall of the left unicornuate uterus model 1. After that, the bottom end of the limiting rod 31 is inserted into the insertion groove 33 to complete the connection between the two.

[0031] Furthermore, an automatic limiting mechanism 4 is provided at the top of the inner wall of the insertion slot 33, and the automatic limiting mechanism 4 includes a limiting slot 41, a limiting block 42 and a compression spring 43. The top of the inner wall of the insertion slot 33 is provided with a square limiting slot 41, and a limiting block 42 that slides therewith is provided between the inner walls of the limiting slot 41.

The outer wall of the right-angled triangle structure at the bottom of 42 is a slope, and its cross-sectional width gradually decreases from the top to the bottom. By setting an automatic limiting mechanism 4, it is possible to prevent the left unicornuate uterus model 1 and the right unicornuate uterus model 2 from accidentally detaching during use after being connected. Specifically, when the limiting rod 31 is inserted into the connecting groove 32, its inner end contacts the slope of the limiting block 42. The inward thrust of the limiting rod 31 acts on the slope to generate a partial upward component of force to push the limiting block 42 into the limiting groove 41. After the bottom end of the limiting rod 31 is inserted into the insertion groove 33, the outer end of the limiting block 42 presses the top end of the limiting rod 31 tightly through the action of the compression spring 43.

[0032] Furthermore, the right side wall of the vaginal groove 15 of the left unicornuate uterus model 1 and the left side wall of the vaginal groove of the right unicornuate uterus model 2 both form openings, and a partition 5 is provided at the opening. The inner end of the left side wall of the partition 5 on the left is hinged to the inner wall of the vaginal groove 15 through a hinge 6, and the inner end of the right side wall of the partition 5 on the right is hinged to the inner wall of the vaginal groove 15 through a hinge 6. The partition 5 can be hinged by the hinge 6 and flipped to fit the inner wall of the vaginal groove 15, and can also be flipped to close the opening. When the left unicornuate uterus model 1 and the right unicornuate uterus model 2 are connected, the partition 5 is flipped to fit the inner wall of the vaginal groove 15, that is, the vaginal grooves 15 on both sides are merged into one vaginal groove, thereby forming a double uterus and single vagina morphology with abnormal uterine development.

[0033] Furthermore, it also includes a rudimentary uterine horn model 7, which includes a rudimentary uterine horn part 71, a rudimentary fallopian tube part 72, a rudimentary ovary part 73 and a connecting piece 74. The rudimentary uterine horn part 71 is an elliptical structure, and its front wall forms an elliptical rudimentary uterine horn trough 75. The front wall of the rudimentary fallopian tube part 72 forms a slender rudimentary fallopian tube trough 76. The right end of the rudimentary uterine horn trough 75 is connected to the left end of the rudimentary fallopian tube trough 76. The rudimentary ovary part 73 is connected to the lower right side wall of the rudimentary uterine horn part 71; the lower left side wall of the rudimentary uterine horn part 71 is connected to the top of the connecting piece 74, and the left side wall of the connecting piece 74 is connected to the left unicornuate uterine model 1 through the connecting mechanism 3. The connecting piece 74 of the rudimentary uterine horn model 7 is connected to the left unicornuate uterine model 1 through the connecting mechanism 3 to form a rudimentary uterine horn morphology with abnormal uterine development.

[0034] Furthermore, it also includes a model base 8, which includes a base 81, a support rod 82, a connecting sleeve 83 and an introduction card placement seat 84. The base 81 has a square structure, and two support rods 82 are connected to the middle of its top. The introduction card placement seat 84 is provided in the middle of the top rear end of the base 81. The introduction card placement seat 84 has a square structure, and a square slot 85 for inserting the introduction card is provided in the middle of the top along the length direction.
