Description

Technical Field

[0001] The utility model relates to a rectum and anal canal lesion teaching model, belonging to the technical field of teaching tools. Background Art

[0002] Anorectal diseases refer to diseases that occur in the anorectal area, and common ones include hemorrhoids, anal fistulas, perianal abscesses, anal fissures, and rectal prolapse. At present, clinical teaching focuses on the mechanism of hanging thread for anal fistulas, the method of tightening thread, the location of perianal abscesses and the operation of puncture and drainage, and the difference between hemorrhoids and anal papilloma. In the process of medical teaching, if students only learn by looking at pictures or explaining without demonstration models, it is difficult to learn and cannot be remembered well. In order to enable students to understand the body structure and treatment steps more intuitively and clearly, teachers often use teaching models for teaching. For example, the Chinese utility model patent with the authorization announcement number CN214541280U discloses an intelligent teaching mold for complex anal fistula, and specifically discloses a model body, the bottom end of which is fixedly connected to a column, the bottom end of which is connected to the transmission output end of a forward and reverse motor, the motor box is sleeved on the outside of the forward and reverse motor, the bottom end of which is fixedly connected to the surface of a gear seat, one side of which is meshed with a gear plate, the bottom end of which is connected to the middle position of the base surface through a shaft seat, a battery is installed inside the base, and a rubber pad is bonded to the middle position of the lower surface of the base. However, the teaching components of the model are all fixed on the model body, and teaching can only be done through oral description and the appearance of the model, and it is impossible to show students the specific process of thread-cutting treatment.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0022] Embodiment: A teaching model of rectal anorectal lesions, comprising: Figure 1-3 As shown, the model body 1 includes some anatomical structures of the rectum and anal canal, such as anal sphincter, mucosa, venous vascular network, etc. The lower part of the model body 1 has an anus 12, and an anal fistula simulation mechanism 2 is detachably connected to the inner wall of the anus 12. Figure 2As shown, the anal fistula simulation mechanism 2 includes a linear section 3, on which three lamp beads 4 are installed. The lamp beads 4 are distributed longitudinally and divide the linear section 3 into three areas. In this embodiment, the lamp beads 4 can change three colors. Before the simulation starts, the lamp beads 4 are red to indicate that the treatment has not started. When the lead wire passes through the corresponding position, the position will turn yellow to indicate which position has been treated. After that, the treated position will turn green after a period of time to indicate that the part has healed itself after a period of time. Three sensors 5 connected and fixed to the linear section 3 are placed on the side of the lamp beads 4. The sensors 5 correspond to the lamp beads 4 one by one. The sensors 5 use light sensors. When the lead wire touches different positions, the sensor 5 at the position controls the corresponding lamp beads 4 to turn yellow. The sensor 5 and the lamp bead 4 are connected to a control board and a power supply, and the control board and the power supply are placed outside or inside the model body 1. Since the control board and the power supply are conventional components in this field and can be obtained commercially, they are not described in detail. Three first magnetic blocks 6 are placed on the other side of the lamp bead 4. The first magnetic block 6 is embedded in the linear section 3 so that the outer surface of the first magnetic block 6 coincides with the outer surface of the linear section 3. The first magnetic block 6 magnetically attracts the second magnetic block 7. The outer side of the second magnetic block 7 is bonded with an anal fistula lesion mold block 8. The second magnetic block 7 is embedded in the anal fistula lesion mold block 8 so that the outer surface of the second magnetic block 7 coincides with the surface of the anal fistula lesion mold block 8, which will not affect the sliding of the lead wire. The first magnetic block 6 and the second magnetic block 7 are used to make the anal fistula lesion mold block 8 fit again after being separated during the resection simulation process without falling off. A threading groove 9 for inserting the lead wire is formed between the anal fistula lesion mold block 8 and the side wall of the line section 3; the anal fistula lesion mold block 8 is made of transparent material so that the light of the lamp bead 4 can pass through the anal fistula lesion mold block 8 and appear; the outer side of the lower part of the model main body 1 is detachably connected to the perianal abscess mold block 10. The anal fistula lesion mold block 8 has two first lead wire grooves 13 located between the second magnetic block 7; the line section 3 has a second lead wire groove 25 corresponding to the first lead wire groove 13, and the first lead wire groove 13 and the second lead wire groove 25 are used to allow the lead wire to be stuck in the first lead wire groove 13 during the simulation explanation, so as to prevent the anal fistula lesion mold block 8 from protruding, so as to facilitate the teacher to explain the anal fistula lesion mold block 8 in different areas. Figure 1As shown, the anus 12 has a raised portion 17 and a recessed portion 18, and the raised portion 17 and the recessed portion 18 are continuously and alternately distributed; the lower end of the raised portion 17 is connected and fixed with a triangular anal papilloma mold block 19. The inner side of the anus 12 is fixedly connected with an intra-anal abscess mold block 20. The inner wall of the model body 1 is connected and fixed with an internal hemorrhoid mold block 21; the lower end of the model body 1 is connected and fixed with an external sore mold block 22. The lower end of the model body 1 is connected with a support rod 23, and the other end of the support rod 23 is connected with a base 24, so that the model body 1 can be placed on the desktop for explanation and display. Therefore, in this embodiment, the lead wire is inserted into the threading groove 9, and then the ends of the lead wire are knotted, and then the lead wire is pulled outward so that the lead wire passes between the anal fistula lesion mold block 8 and the wire section 3. At the same time, the lead wire slides from top to bottom on the sensor 5, and the sensor 5 changes the color of the corresponding position of the lamp bead 4 according to the position of the lead wire. At the same time, the anal fistula lesion mold block 8 is made of transparent material, and the light is displayed through the anal fistula lesion mold block 8 to clearly show the position of the lead wire removal. The model body 1, anal papilloma mold block 19, intraanal abscess mold block 20, internal hemorrhoid mold block 21 and external sore mold block 22 are all made of plastic material. Figure 4 As shown, when the lead wire is just inserted into the threading groove and tied, the lamp beads 4 emit red light. Figure 5 After the lead wire is pulled to the position shown in the figure, the top lamp bead 4 is yellow, and after a period of time, the lamp bead turns green; Figure 6 As shown, the middle lamp bead 4 is yellow, and after a period of time, the lamp bead turns green; then the lead wire is completely pulled out, the lamp bead 4 at the bottom is yellow, and after a period of time, the lamp bead turns green.

[0023] Preferably, if Figure 3 As shown, the perianal abscess mold block 10 includes a first magnetic joint 14 arranged on the outer side of the lower part of the model body 1, the first magnetic joint 14 is connected to a second magnetic head 15 and cooperates with each other, and an abscess cavity 16 is connected and fixed to the outer side of the second magnetic head 15, and the abscess cavity 16 is made of rubber. A simulated liquid is placed in the abscess cavity 16, so that students can simulate the treatment of the abscess cavity 16. The first magnetic joint 14 and the second magnetic head 15 connect the abscess cavity 16 with the model body 1, so that the abscess cavity 16 can be easily replaced after being damaged during teaching.

[0024] How it works

[0025] The model body 1 has some anatomical structures of the rectum and anal canal. Anal papilloma mold block 19, anal abscess mold block 20, internal hemorrhoid mold block 21 and external sore mold block 22 are fixed on the model body 1, so that students can observe and understand them. Then, the anal fistula simulation mechanism 2 is used to simulate the wire cutting treatment method for students. At the beginning, the lamp bead 4 is all red. The lead is inserted into the threading groove 9, and then the ends of the lead are knotted. Then the lead is pulled outward so that the lead passes between the anal fistula lesion mold block 8 and the wire section 3. At the same time, the lead slides on the sensor 5, and the corresponding sensor 5 turns the corresponding lamp bead 4 yellow, so that students know which position is treated. After that, the treated position will turn green after a period of time, indicating that the part has healed by itself after a period of time. After the lead passes between the anal fistula lesion mold block 8 and the wire section 3, the first magnetic block 6 and the second magnetic block 7 re-adsorb and connect the anal fistula lesion mold block 8 and the wire section 3.
