Description

Technical Field

[0001] The utility model belongs to the technical field of dental operation and training, and particularly relates to an oral operation and training model. Background Art

[0002] With the development of more than half a century, oral implant technology has become a conventional technology for tooth restoration and has been widely applied in clinics. The key to the successful implementation of oral implant technology lies in the operation of doctors. However, for a long time, oral implant still mainly relies on implant manufacturers to lead the training of implant technology in the form of study classes, and in the process of training, it also more relies on methods such as instructor demonstration, students' viewing, and operation on a three-dimensional oral model. There is a large difference between this kind of operation and actual clinical operation. The main reasons are as follows: When observing, since the traditional three-dimensional oral model can only realize basic tooth planting operations, on the one hand, once the dental alveolus is damaged, a new model is directly replaced, resulting in increased costs, which leads to a decrease in the frequency of training and demonstration, and further compresses the practice time of students. On the other hand, when operating on the surface of the dental alveolus in reality, there is bleeding of the surface skin texture, while the traditional oral model does not have this function, and the simulation degree is obviously poor. In addition, since the inferior alveolar nerve and vascular bundle runs through the alveolar process of the mandible, once the drill or tool is operated improperly, resulting in surgical errors, it is also possible to damage or even cut off the inferior alveolar nerve and vascular bundle, leading to accidental bleeding, numbness and loss of sensation of the skin and lips in the lower part of the face after the operation, and even directly necrosis of multiple teeth connected to the inferior alveolar nerve and vascular bundle; obviously, this is not shown in the traditional oral model either, which makes students gradually reduce or even lose the sense of vigilance and urgently needs to be solved. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide an oral operation and training model that can achieve the purpose of implanting teeth operation and training with high simulation degree.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An oral operation and training model, including a dental alveolus, the area on the dental alveolus for implanting teeth training or intraoral suture constitutes an operation area, and is characterized in that: a first balloon is arranged in the surface area of the operation area, and a first colored liquid for simulating blood at the surface of the dental alveolus is filled in the first balloon.

[0006] Preferably, the operation area includes a matrix whose hardness matches that of the alveolar bone, and a simulation layer simulating the surface of the dental alveolus is covered on the matrix, and the first balloons are densely arranged in the simulation layer.

[0007] Preferably, the color of the first colored liquid is red.

[0008] Preferably, along the gum direction, a second balloon for simulating the inferior alveolar neurovascular bundle is further arranged in the operation area in the mandibular region, and the second balloon is filled with a second colored liquid for simulating the blood at the inferior alveolar neurovascular bundle. There is a color difference between the second colored liquid and the first colored liquid or a difference in the maximum simulated blood loss between the two.

[0009] Preferably, the second balloons are linearly distributed in sequence along the direction of the inferior alveolar neurovascular bundle in the operation area, and the volume of the second balloon is larger than that of the first balloon.

[0010] Preferably, the color of the second colored liquid is red.

[0011] Preferably, threaded holes are arranged at the bottom of the operation area, and blind hole-shaped installation holes for the operation area to be inserted into are recessed in the corresponding areas of the gum. After the operation area is inserted into the installation hole, fastening screws penetrate the bottom of the installation hole from bottom to top and are threadedly engaged with the threaded holes, so as to form a detachable fit between the operation area and the gum.

[0012] Preferably, both sides of the simulation layer extend to both sides of the base and protrude from both sides of the base to form eaves. Corresponding fitting notches are recessed at the hole ends of the installation holes. After the operation area is fixed at the installation hole, a surface fitting state is formed between the eaves and the fitting notches on both sides of the gum.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1) Through the above solution, the present utility model utilizes the liquid-containing property of the balloon. After filling the first colored liquid into the first balloon, it is buried in the surface area of the simulated operation area. In this way, once the drill or tool touches these balloons, the balloons will burst and the colored liquid will seep out, which can vividly show the bleeding scene on the surface of the gum during the operation, and the simulation degree is extremely high.

[0015] Of course, since the present utility model relates to the operation occasion of the surface area of the gum or the gingival area, the actual operation situations such as oral suture and using a scalpel to cut the epidermis are applicable to the present utility model.

[0016] 2) When designing the first balloon, several can be arranged, and even the volume sizes can be different. In this way, multiple first balloons will not affect the simulated bleeding of drilling at other positions in the same operation area after the current drilling simulation bleeding, enabling multiple tooth implantations in the same operation area. At the same time, the volumes of the first balloons can also be different, which can make the simulated blood loss at each tooth implantation point different and also improve the vividness, which will not be elaborated here. In addition, the number of the first balloons should be as dense as possible, that is, as many as possible, to maximize the simulation effect. The same applies to the oral suture operation.

[0017] 3) The present utility model also arranges a second balloon for simulating the inferior alveolar neurovascular bundle in the operation area at the mandibular region, aiming to simulate the inferior alveolar neurovascular bundle. As an important nerve area of the human body, the inferior alveolar neurovascular bundle must not be damaged, so it is strictly prohibited for the drill bit or tool to touch it. Through the additionally arranged second balloon in the present utility model, once it is touched and ruptured, more bleeding will occur to improve the simulation effect; or pigments of different colors from the first balloon can be arranged to achieve a visual reminder effect. The number of the second balloons arranged is theoretically denser, which not only ensures continuity to form a line but also meets the requirements of multiple punctures.

[0022] The actual corresponding relationship between each label and the component name of the present utility model is as follows:

[0023] 10 - dental alveolus; 11 - operation area; 11a - simulation layer; 11b - matrix; 11c - cornice; 11d - threaded hole; 12 - mounting hole; 12a - fitting notch;

[0024] 20 - first balloon; 30 - second balloon. Detailed Description of the Preferred Embodiments

[0025] For the convenience of understanding, in combination with Figures 1-4 , the following further describes the specific structure and working mode of the present utility model:

[0026] The actual structure of the present utility model refers to Figures 1-2 shown. Its overall structure still follows the current oral model structure, and the difference is that operation areas 11 are arranged at both ends or a single end area of the upper jaw and / or the lower jaw. Among them:

[0027] The outer shape of the operation area 11 refers to Figures 3-4 shown. The upper surface of the simulation layer 11a presents an arc shape that matches the overall trend of the dental alveolus 10. Below the simulation layer 11a is the matrix 11b. Both sides of the simulation layer 11a slightly protrude from both sides of the matrix 11b and form Figure 1 and Figure 3 shown cornices 11c, so as to be used for matching Figure 2The mating notch 12a shown is used to make the adhesion stronger after the operation area 11 is installed, and the overall appearance is more beautiful. In addition, to ensure the disassembly and assembly of the operation area 11 for repeated use, the detachable threaded fastening effect can be achieved through the cooperation of fastening screws, mounting holes 12 and even threaded holes 11d.

[0028] Inside the base body 11b, the first balloon 20 and the second balloon 30 are also arranged respectively in the present utility model; during design, the liquid output amounts of the second balloon 30 and the first balloon 20, that is, the simulated blood loss amounts, should be different, so that the operator can clearly know which balloon is damaged at present. Of course, if the colors of the colored liquids in the two balloons are already distinguishable, there is no need to pay attention to the difference in the liquid output amounts. During design, it is preferably to distinguish the two by the maximum liquid output amount, so that the colors of the internal liquids are all red, which can better achieve the effect of simulation operation.

[0029] The positions of the first balloon 20 and the second balloon 30 are also particular. The first balloon 20 is located in the simulation layer 11a and is used to simulate the normal bleeding of the gum when it bursts. Only the operation area 11 at the mandibular part is provided with the second balloon 30, and the second balloon 30 is arranged in sequence along the direction of the mandibular neurovascular bundle and is used to simulate the bleeding of the mandibular neurovascular bundle when it bursts and play a prompting function to prompt the operator that an illegal operation has occurred.
