Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a diagnostic curettage model. Background Art

[0002] Diagnostic curettage is the abbreviation of diagnostic curettage, which is the most commonly used method for diagnosing intrauterine diseases. Its purpose is to scrape the endometrium and endometrial lesions, perform biopsy, and make a pathological diagnosis. Diagnostic curettage is divided into general diagnostic curettage and segmented diagnostic curettage. General diagnostic curettage is suitable for the diagnosis of abnormal uterine bleeding, anovulatory dysfunctional uterine bleeding, residual tissue in the uterine cavity for infertility, etc. Segmented diagnostic curettage is mostly performed during bleeding. It is suitable for postmenopausal uterine bleeding or elderly patients who are suspected of endometrial cancer or need to know whether the cervical canal is involved. Diagnostic curettage generally requires a doctor with certain experience to perform. As an intern, in addition to the theoretical explanations in textbooks, more teaching practices are carried out with the help of corresponding models.

[0003] The utility model patent with application number CN202222168958.4 discloses a gynecological teaching and training model, including: a vulva model, an abdominal model and at least one color of plasticine; the abdominal model is provided with pelvic and genital anatomical structures, and the genital anatomical structures include vagina, uterus, fallopian tubes and ovaries; the abdominal model and the uterus are openable structures; the uterus includes a uterine body and a cervical canal, and the plasticine is stuck in the uterus. This model can realize the teaching and simulation training of segmented diagnostic curettage. Although this model can judge the different parts of the curettage according to the color of the plasticine, thereby testing the correctness of the student's curettage technique; however, it cannot simulate the diagnostic curettage under bleeding state, which is quite different from the actual operation.

[0025] See also Figure 1-Figure 3 In a preferred embodiment of the utility model, a curettage model includes a uterus model 1, a vaginal opening 4 is opened on the uterus model 1, and a plurality of simulated blood vessels 2 are arranged on the uterus model 1, one end of the simulated blood vessel 2 is connected to a simulated blood storage device arranged on the outside of the uterus model 1, and the other end is located on the inner wall of the uterus model 1 and is connected to the inside of the uterus model 1, and each simulated blood vessel 2 is provided with a blood vessel closing mechanism 21 on one end of the inner wall of the uterus model 1, and the blood vessel closing mechanism 21 is slidably connected to the uterus model, and opens and closes the simulated blood by sliding. The tube mouth, each blood vessel closing mechanism 21 can be detachably mounted with a content model 3 for simulating uterine contents; the uterus model 1 can be detachably mounted with a diagnostic curettage tool 5 for scraping the content model 3 from the inner wall of the uterus model 1, and the diagnostic curettage tool 5 is movably connected to the uterus model 1; the diagnostic curettage tool 5 includes a scraping head 51 and an operating rod 52, one end of the operating rod 52 is connected to the scraping head 51, and the scraping head 51 extends into the interior of the uterus model 1 through the vaginal opening 4 under the action of the operating rod 52, and the end of the operating rod 52 that is not connected to the scraping head 51 is located outside the uterus model 1. The simulated blood can be injected into the uterine model 1 through the simulated blood vessel 2, and the simulated blood flows out from the vaginal opening 4, thereby simulating the bleeding state to perform the diagnostic curettage training. In the bleeding state, the scraper head 51 is extended from the vaginal opening 4 into the uterine model 1, and the content model 3 is scraped off by operating the operating rod 52 located outside the uterine model 1. In the process of scraping off the content model 3, the blood vessel closing mechanism 21 will be driven to slide, thereby closing the simulated blood vessel 2 and stopping the bleeding, thereby being able to perform the diagnostic curettage simulation training closer to the actual situation. Preferably, the content model 3 is detachably connected to the closing mechanism by Velcro or magnetic attraction, and the structure is simple, and it is convenient to scrape off the content model 3. Moreover, the colors of several of the content models 3 are different, and the content models 3 of different colors can be placed in different parts according to the needs of the assessment, and the different parts of the curettage are judged according to the color of the scraped content model 3, thereby testing the correctness of the trainee's curettage technique.

[0026] Preferably, the uterus model 1 is composed of two detachable parts. After the uterus model 1 is disassembled into two parts, it is more convenient to place the content model 3 at the designated position of the uterus model 1. In this embodiment, the uterus model 1 is specifically disassembled into an upper and lower part, wherein the simulated blood vessel 2 is located in the upper part 11 of the uterus model, and the vaginal opening 4 is located in the lower part 12 of the uterus model. Such a setting will not affect the direction of the simulated blood vessel 2, and the structure is simpler and more convenient to use. More preferably, the two parts of the uterus model 1 are detachably connected by magnetic attraction. In addition, several simulated blood vessels 2 are connected to the main pipe, and the main pipe is connected to the simulated blood storage device through a suction pump. A valve is provided at one end of each simulated blood vessel 2 close to the main pipe, and the simulated blood in the simulated blood storage device is introduced into the simulated blood vessel 2 through the suction pump. The valve on each simulated blood vessel 2 can be used to control whether the simulated blood needs to be introduced into the simulated blood vessel 2 to adapt to different methods of curettage tests.

[0027] Preferably, a first placement groove 13 is provided on the inner wall of the uterine model 1, the simulated blood vessel 2 is placed on the bottom of the first placement groove 13, and the blood vessel closing mechanism 21 is accommodated in the first placement groove 13; the blood vessel closing mechanism 21 includes two slide grooves 211, a slider 212 and a blocking block 213, the slide grooves 211 are provided on the groove walls on opposite sides of the first placement groove 13, the two slide grooves 211 are both provided on the inner wall of the uterine model 1, and are respectively arranged on both sides of the radial direction of the simulated blood vessel 2; the slider 212 is slidably connected to the two slide grooves 211, and a blocking block 213 is provided on the slider 212, and the blocking block 213 opens and closes the simulated blood vessel 2 under the drive of the slider 212; the content model 3 is detachably installed on the slider 212, and the content model 3 and the blocking block 213 are respectively arranged on opposite sides of the slider 212. When it is necessary to perform curettage training in a bleeding state, the blocking block 213 is away from the simulated blood vessel 2, and the simulated blood vessel 2 is in an open state, and blood can be injected. When the scraper head 51 scrapes the content model 3, it will drive the slider 212 to slide along the slide groove 211, thereby driving the blocking block 213 to move. When the blocking block 213 is facing the simulated blood vessel 2, the simulated blood vessel 2 can be blocked, thereby closing the simulated blood vessel 2 to stop bleeding. At this time, the slider 212 reaches the groove wall of the slide groove 211 and cannot continue to slide. The content model 3 is scraped off from the inside of the uterus model 1 under the action of the scraper head 51. In addition, the blood vessel closing mechanism 21 does not protrude from the inner wall of the uterus model 1, only the content model 3 protrudes from the inside of the uterus model 1, which is closer to the real situation.

[0028] More preferably, a second placement groove 2121 is opened on the slider 212, and the blocking block 213 is connected to the compression spring 2122 in the second placement groove 2121. When the compression spring 2122 is in a natural state, one end of the blocking block 213 is located in the second placement groove 2121, and the other end of the blocking block 213 is located outside the second placement groove 2121, and the simulated blood vessel opening is inserted when the placement groove 2121 is opposite to the simulated blood vessel opening; when the compression spring 2122 is in a compressed state, one end of the blocking block 213 can be detachably inserted with the content model 3, and the other end is located in the second placement groove 2121. When the second placement groove 2121 is not facing the simulated blood vessel 2, the end of the blocking block 213 close to the inner wall of the uterus model 1 is squeezed by the bottom groove wall of the first placement groove 13, and the compression spring 2122 is in a compressed state. The end of the blocking block 213 away from the inner wall of the uterus model 1 can be detachably inserted with the content model 3. When the scraper head 51 scrapes the content model 3, the content model 3 drives the slider 212 to slide on the slide groove 211 under the action of the Velcro or magnetic attraction and the blocking block 213. At this time, the content model 3 cannot be removed by the action of the scraper head 51 alone. The simulated blood vessel opening 2 is scraped off to avoid the situation where only the contents are scraped off without closing the simulated blood vessel opening 2; when the slider 212 moves to the second placement groove 2121 facing the simulated blood vessel opening 2, the extrusion force on the blocking block 213 disappears, and the compression spring 2122 is in a natural state. The end of the blocking block 213 close to the inner wall of the uterus model 1 is inserted into the simulated blood vessel opening, and the end of the inserted content model 3 is located in the second placement groove 2121. At this time, the simulated blood vessel opening 2 is closed, and the content model 3 can be easily scraped off under the action of the scraper head 51.

[0029] In this embodiment, preferably, a pull-out block 2131 for pulling out the block 213 from the simulated blood vessel opening is provided on the side wall of the blocking block 213. One end of the pull-out block 2131 is connected to the blocking block 213, and the other end is movably provided with a slider 212, and is located outside the slider 212 and accommodated in the first placement groove 13. The pull-out block 2131 is slidably connected to the slider 212, and the sliding direction of the pull-out block 2131 is perpendicular to the sliding direction of the slider 212. When it is necessary to remove the block 213 inserted in the simulated blood vessel opening, the pull-out block 2313 can be moved to slide on the slider 212, thereby driving the block 213 to be separated from the simulated blood vessel opening. At this time, pushing the slider 212 can drive the block 213 away from the simulated blood vessel 2, so that the simulated blood vessel opening is in an open state, and the next diagnostic curettage test can be performed. In addition, a pull ring can be provided on the pull-out block 2331 to facilitate the pulling of the pull-out block 2131.
