Description

Technical Field

[0001] The utility model relates to the technical field of demonstration models, in particular to a light-enabled demonstration model of anal fistula and perianal abscess. Background Art

[0002] There are several funnel-shaped anal crypts with cups facing upwards at the junction of the anorectum. The anal glands enter the anal crypts through the anal ducts and secrete mucus that is discharged from the anal crypts. Under normal circumstances, they play a role in lubricating feces and protecting the anal canal. However, under some pathological reasons, such as intestinal bacteria causing anal gland infection through the anal crypts, primary lesions are formed, and the corresponding anal crypts are the primary internal openings of the infection lesions. The inflammation further spreads to the gaps in the anal canal and the surrounding tissues of the rectum, forming lesions of various types and shapes, such as perianal abscesses and anal fistulas.

[0003] Perianal abscesses and anal fistulas require surgical treatment, and the surgical method needs to be designed according to the location, range and relationship of the lesion with the surrounding tissue structure. At present, the overall preoperative evaluation of the lesion is mainly carried out through imaging examinations such as anal magnetic resonance imaging. Surgeons form a three-dimensional impression in their minds based on the image reading, which is used to design surgical methods, talk with patients before surgery, discuss with colleagues, academic exchanges, teach students, and guide junior doctors. At present, in order to visualize these lesions, surgeons draw schematic diagrams based on the image reading, but the graphics are flat, while the lesions are three-dimensional and often have complex shapes. Therefore, the use of plane drawings for designing surgical methods, preoperative conversations with patients, discussions with colleagues, academic exchanges, teaching students, and guiding junior doctors has great limitations.

[0036] A light-enabled demonstration model of anal fistula and perianal abscess provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings. Example 1

[0037] Combination Figure 1-4 As shown, the utility model provides a light demonstration model of anal fistula and perianal abscess, including an levator ani muscle module 100, a rectal end module 200, an internal anal sphincter module 300 and an external anal sphincter module 400. The levator ani muscle module 100 includes a levator ani muscle 1 110 and a levator ani muscle 2 120 bonded to the levator ani muscle 1 110.

[0038] Among them, the levator ani muscle module 100 and the external anal sphincter module 400 are fitted together, and the internal anal sphincter module 300 is usually installed in the inner cavity of the external anal sphincter module 400, with a certain gap between the two, which is convenient for marking the lesion or placing it between the two layers in the later stage, so as to facilitate the later demonstration.

[0039] The rectal end module 200 includes a rectal end 1 210 that fits with the inner wall of the levator ani muscle 1 10 and a rectal end 220 that fits with the inner wall of the levator ani muscle 2 120 . The rectal end 1 210 and the rectal end 220 fit with each other.

[0040] The anal internal sphincter module 300 includes an internal sphincter 1 310 integrally formed with the rectal end 1 210 and an internal sphincter 2 320 integrally formed with the rectal end 220 , and the internal sphincter 1 310 and the internal sphincter 2 320 are in contact with each other.

[0041] The external anal sphincter module 400 includes an external sphincter 1 410 that is attached to the outer wall of the internal sphincter 1 310, an external sphincter 2 420 that is attached to the outer wall of the internal sphincter 2 320, and an anal skin model 500 that is attached to the bottom of the internal sphincter 1 310 and the bottom of the internal sphincter 2 320. The external sphincter 1 410 and the external sphincter 2 420 are attached to each other; the external anal sphincter module 400 and the anal skin model 500 are in contact with each other.

[0042] Furthermore, the shape of the external sphincter 1 410 is equal to the shape of the external sphincter 2 420 , and the outer edge of the top of the external sphincter 1 410 is chamfered. This shape design facilitates the separation of the external sphincter 1 410 and the external sphincter 2 420 .

[0043] Furthermore, two insertion rods are installed on one side of the internal sphincter 2 320 and one side of the external sphincter 2 420. The internal sphincter 2 320 is plugged with the internal sphincter 1 310 through the insertion rods thereon, and the external sphincter 2 420 is plugged with the external sphincter 1 410 through the two insertion rods thereon. The use of this structural design can improve the structural firmness of the device. Example 2

[0044] Combination Figure 4 As shown, on the basis of the first embodiment, a plurality of short shafts 600 are installed on the top of the perianal skin model 500. The plurality of short shafts 600 are arranged in a ring shape at equal intervals. The short shafts 600 are provided to provide conditions for strengthening the internal sphincter 1 310 and the internal sphincter 2 320.

[0045] Specifically, a plurality of short shafts 600 are respectively inserted into the internal sphincter 1 310 and the internal sphincter 2 320 in an interference fit manner, and the short shafts 600 are made of plastic material. With this structural design, the internal sphincter 1 310 and the internal sphincter 2 320 can be firmly connected. Example 3

[0046] Combination Figure 3 As shown, in the above embodiment, two magnets 700 are embedded on one side of the internal sphincter 310 and one side of the external sphincter 410. The magnet 700 is provided to facilitate the merging of the internal sphincter 310 with the internal sphincter 2 320 and the merging of the external sphincter 410 with the external sphincter 2 420.

[0047] Specifically, two magnets 2 800 are embedded on one side of the internal sphincter 2 320 and one side of the external sphincter 2 420. The magnet 1 700 and the magnet 2 800 are magnetically attracted to each other. The magnet 2 800 is provided to ensure that the internal sphincter 1 310 and the internal sphincter 2 320 are combined, and the external sphincter 1 410 and the external sphincter 2 420 can be flexibly spliced.

[0048] The working principle and use process of the utility model are as follows: based on the normal anatomical structure related to the range of perianal abscess and anal fistula, an assemblable, modular perianal anatomical model is established, including: anal levator muscle module 100, rectal end module 200, internal anal sphincter module 300, external anal sphincter module 400 and perianal skin model 500, and can be further refined according to the anatomy, for example, external sphincter 1 410 and external sphincter 2 420 can be split into two parts.

[0049] The green module is used as the lesion mark, and the green module can be made of green adhesive strips, plasticine and other materials. According to the specific conditions of each patient, in the above model, the parts that mark the detailed status of the lesion are made of flexible and transparent materials and can be dyed to distinguish. After the lesion is marked with the green module, the scalpel, scissors and other instruments can be used to simulate the operation on the model.

[0050] In combination with the above, in the above embodiment, the green module can be placed in the gap or around the modules, or can be marked in the inner cavity of each module, wherein each module can form a hollow structure, which is detachable and convenient for embedded filling, thereby facilitating lesion identification.

The power module can be an external power supply or an embedded battery, preferably an external power supply. The light control of the multi-color LED lamp beads 900 is achieved through an external power supply controller, wherein the light control of the multi-color LED lamp beads is a light control circuit commonly used in the prior art. The multi-color LED lamp beads 900 are usually red, yellow and blue three-color lamp beads, which can form a variety of color changes, which is convenient for simulating different diseases.

[0052] The above components are usually made of plastic materials, and can also be made of flexible materials such as rubber, silicone and other related materials.
