Description

Technical Field

[0001] This application relates to a medical demonstration instrument, specifically a gastric lesion demonstration device. Background Art

[0002] Currently, the tools or means for the popularization and teaching of gastric diseases mainly include textbook illustrations, multimedia displays, etc., lacking more intuitive tools and teaching means. In order to more intuitively and effectively display, observe and learn about gastric diseases, various gastric disease display models or devices are provided in the existing patent literature.

[0003] For example, patent document CN113077693A discloses a display device for a gastric cancer model. The device includes a cabinet body, a gastric cancer model and a camera device. A turntable is rotatably arranged between a first plate body and a second plate body on the upper end surface of the cabinet body. A snake tube is vertically fixed on the slider. A connecting ring is erected between the first plate body and the second plate body. A plurality of placement grooves are formed on the front surface of the second plate body. A lower connecting rod and an upper connecting rod are arranged on the gastric cancer model. The lower connecting rod is threadedly connected to the turntable. The upper connecting rod is inserted into the connecting ring. The camera device includes a camera and a display. The camera is fixedly arranged on the snake tube.

[0004] Another example is patent document CN209625585U, which discloses a gastric pathology demonstration model. The model includes a gastric demonstration model body, which is composed of a left gastric demonstration model and a right gastric demonstration model. Pyloric part models and esophageal models are arranged on both the left gastric demonstration model and the right gastric demonstration model. From the inside to the outside, the left gastric demonstration model and the right gastric demonstration model are successively provided with a mucosal layer model, a submucosal layer model, a muscular layer model and a serous layer model. The muscular layer model includes an oblique fiber layer model, a circular fiber layer model and a longitudinal fiber layer model.

[0005] Another example is patent document CN203433725U, which discloses a gastric resection display model. The model is composed of an upper part of the stomach, a resected part of the stomach, the duodenum, a bracket and a base. The upper end of the resected part of the stomach is connected to the upper part of the stomach, and the lower end is connected to the duodenum. The whole gastric model is fixed on the base through the bracket. The lower end of the upper part of the stomach and the upper end of the duodenum are made of elastic silica gel. After removing the resected part of the stomach, the lower end of the upper part of the stomach can be connected to the upper end of the duodenum, thereby showing the morphology after gastric resection.

[0006] The above existing gastric or gastric disease display models or devices generally have only a model with a single morphology, which mainly shows the normal, or a certain pathological stage, or the stomach after surgery. It is difficult to compare the diseased stomach with the normal stomach during the display process, and it is also difficult to compare the stomachs in different pathological stages with each other. The demonstration effect is poor, it is difficult to leave a deep impression, and it is also difficult to achieve good popularization and teaching effects. Summary of the Invention

These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0027] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present application.

[0028] As Figures 1 to 4 shown, the gastric lesion demonstration device of the embodiment of the present application includes a box body 100, a rotating assembly 200 and several gastric models 300. A concave display window 110 is provided on the front surface of the box body 100. The rotating assembly 200 includes a turntable 210 and a motor 220 for driving the turntable 210 to rotate; during the rotation of the turntable 210, part of the disk surface is exposed in the display window 110, and the other part is hidden inside the box body 100. The several gastric models 300 include models respectively showing different stages of gastric lesions, which are fixedly arranged around the disk surface of the turntable 210 and are successively displayed in the display window 110 as the turntable 210 rotates.

[0029] For the box body 100, its shape is usually selected as a square box, but it is not limited to this shape; box bodies of other shapes that can be used to accommodate the rotating assembly 200 and the gastric models 300 can also be adopted. The material of the box body 100 is not limited to a certain material. Relatively speaking, a plastic material with light weight and easy processing is more likely to be adopted.

[0030] For the display window 110, its function is to sequentially display each gastric model 300. During the display process, the models that are not to be displayed should also be blocked to avoid confusion. In a more specific solution, a first opening 120 is provided in the middle of the front surface of the box body 100, and a second opening 130 is provided at the middle position of the front end of its top surface. The first opening 120 and the second opening 130 are connected to form the display window 110; a partition 140 distributed in an "n" shape is surrounded inside the display window 110 to separate the display window 110 from other parts of the box body 100; a first through opening 141 is provided at the lower part of the partition 140, and second through openings 142 are provided at the two turning positions respectively. The first through opening 141 is used to pass through a part of the turntable 210, and the gastric model 300 can pass through the second through opening 142 during rotation.

[0031] Among them, a first window door 121 that can be opened is provided at the first opening 120, and a second window door 131 that can be opened is provided at the second opening 130; the first window door 121 shown in the figure is a double-door structure, and the second window door 131 is an upward-opening door structure. A limiting block 150 is provided at the inner edge of the display window 110, which is used to block the first window door 121 and the second window door 131 when they are closed, so as to ensure that the first window door 121 and the second window door 131 are flush with the outside of the box body 100 after closing and remain stable at the same time. Of course, the first window door 121 and the second window door 131 can also be directly made of transparent materials. In this case, the gastric model 300 in the display window 110 can be seen whether it needs to be opened or not. In order to increase the viewing angle, the front half parts on both sides of the box body 100 can be made transparent into the display window 110; that is, the front half parts on both sides of the box body 100 and the parts of the partition 140 located on both sides are made transparent.

[0032] In addition, a supplementary light 160 can be provided at the bottom of the display window 110; the turntable 210 is made of a transparent material, or several light-transmitting openings 211 are provided on the turntable 210. During the demonstration, the supplementary light 160 can be used for lighting to clearly display the gastric model 300. The supplementary light 160 can be an LED lamp, and can also share the same switch or control circuit with the motor 220 to start and stop synchronously.

[0033] For the rotating assembly 200, in a more specific solution, the rotating assembly 200 further includes a rotating shaft 230, a bearing block 240, a stop switch 250, and a contact piece 260. The bearing block 240 is fixed to the bottom inside the box body 100; the lower end of the rotating shaft 230 is vertically fixed on the bearing block 240; the bottom of the turntable 210 is fixed to the top of the rotating shaft 230; the motor shaft of the motor 220 and the rotating shaft 230 are in gear transmission or belt transmission; the stop switch 250 is mounted inside the box and close to the rotating shaft 230, and is electrically connected to the motor 220; the contact piece 260 is fixed to the side of the rotating shaft 230, and is used to touch the stop switch 250 after rotating one circle with the rotating shaft 230, so as to control the motor 220 to stop.

[0034] Among them, the motor 220 can be a reduction motor with a slower speed, or a speed reducer can be added to the output end of a conventional motor, or a stepper motor that is easier to accurately control through a circuit can also be selected, so that the turntable 210 rotates at a lower speed, or the rotation control of the turntable 210 is set to intermittent rotation, and each gastric model 300 stays for a period of time during the stop period. The stop switch is also called a micro switch. The stop switch 250 of the present application is not limited to a certain model. Generally, a driving rod or a driving piece is provided at the front end of the stop switch. The driving rod or the driving piece is turned on or off after being touched by the contact piece 260, so as to control the motor 220 to stop. The touched driving rod or driving piece quickly resets and waits for the next round of stop control.

[0035] In addition, a start switch 270 for starting the motor 220 can also be provided on the box body 100 to further control the rotation of the turntable 210 through it. Of course, the start process of the present application is not limited to this method. For example, the start switch can be integrated on the first window 121. When the window is opened, the motor 220 can be immediately started. Another example is that voice control can also be used for control, and a voice broadcast function can also be added to assist in introducing relevant knowledge about different stages of gastric lesions. Obviously, these control methods and the voice broadcast method are all mature technologies in the field, and their control principles, control circuits, etc. are all existing technologies, and the present application will not elaborate on them here. Moreover, the electrical components involved in the present application are not limited to the above-mentioned components. For example, it can also include a battery for power supply, a circuit connecting the motor and the supplementary light, etc. Since these are all conventional settings and do not involve the core functions of the present application, they will not be elaborated on either.

[0036] Regarding the gastric model 300, it should be noted that the gastric model 300 in the specification drawings is only a schematic diagram, not a specific diagram that completely corresponds to the actual normal or diseased stomach. In actual products, models that conform to the actual situation and clearly show the characteristics of the stomach should be made according to the morphology of the stomach in different pathological stages.

[0037] To clearly display the stomach at each pathological stage separately, the stomach model 300 preferably has five models, namely, models for displaying the normal stomach, superficial gastritis, atrophic gastritis, intestinal metaplasia of the stomach, and gastric cancer. In addition, the five stomach models 300 can be arranged according to the evolution process of the pathological changes, so that during the rotation of the turntable 210, the five stages of the normal stomach, superficial gastritis, atrophic gastritis, intestinal metaplasia of the stomach, and gastric cancer are demonstrated in sequence.

[0038] It should be understood that all of the above embodiments are exemplary rather than restrictive. Those skilled in the art, under the concept of this application, any modifications or deformations made to the specific embodiments described above should be within the protection scope of this application.
