Description

Technical Field

[0001] This invention relates to the field of oral medicine teaching and surgical training equipment, and more specifically to a highly realistic oral model for simulating pulp revascularization surgery. Background Technology

[0002] Pulp revascularization is now an important technique for treating pulp necrosis in young permanent teeth and promoting continued root development. The key step of this procedure involves puncturing the apex of the tooth with instruments to induce bleeding in the apical region, allowing blood to enter the root canal and form a blood clot, which then serves as a scaffold for subsequent tissue regeneration.

[0003] Currently, teaching and practice for the aforementioned surgical procedures mostly utilize extracted teeth for practice. However, extracted teeth cannot simulate realistic and controllable periapical bleeding, resulting in limited training effectiveness. Furthermore, while some existing simulation models can mimic root canal morphology, they still cannot realistically simulate the "post-puncture bleeding" process, thus requiring improvement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an oral teaching and training model for pulp blood supply reconstruction. This model can highly simulate the entire process of periapical puncture and bleeding, facilitating intuitive observation by operators and enabling repeated training.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An oral teaching and training model for pulp revascularization includes: The model body is provided with a puncture channel simulating a root canal; A puncture seat, wherein the puncture seat is disposed at the lower end of the puncture channel, and the puncture seat is provided with a bleeding hole communicating with the puncture channel; A simulated membrane is disposed between the puncture channel and the bleeding hole; A driving mechanism is connected to a simulated membrane and is used to drive the simulated membrane to move in order to adjust the simulated membrane to the puncture area corresponding to the bleeding hole. A liquid supply device is connected to a bleeding hole and is used to deliver simulated plasma into the bleeding hole, or to deliver simulated plasma from the bleeding hole to the outside.

[0006] As a further improvement of the present invention, the puncture seat is provided with a sealing groove in the circumferential direction corresponding to the bleeding hole, and the lower end of the puncture channel is provided with a locking block corresponding to the sealing groove. A drive source is used to drive the card block to move up and down to contact and press the simulated film against the sealed card slot.

[0007] As a further improvement of the present invention, the driving source is an electromagnet disposed at the puncture seat, and the end of the locking block is provided with an elastic ring and is connected to the lower end of the puncture channel through the elastic ring.

[0008] As a further improvement of the present invention, the driving mechanism includes a motor and take-up rollers symmetrically arranged on both sides of the puncture seat. The two ends of the simulated film are wound on the two take-up rollers. The output end of the motor is connected to the take-up rollers and is used to drive the take-up rollers to rotate.

[0009] As a further improvement of the present invention, the model body is provided with an absorption mechanism on one side corresponding to the puncture seat. The absorption mechanism includes sponge blocks symmetrically arranged on both sides of the simulation film. The sponge blocks on both sides are used to abut against both sides of the simulation film and to absorb the simulated plasma on the surface when the simulation film moves.

[0010] As a further improvement of the present invention, the sponge is provided with an arc-shaped groove on the side near the puncture seat.

[0011] As a further improvement of the present invention, the liquid supply device includes a liquid storage tank and a liquid supply pump. The liquid storage tank is connected to the bleeding hole through the liquid supply pump, and a pressure sensor is provided in the bleeding hole.

[0012] As a further improvement of the present invention The beneficial effects of this invention are: 1. By using a simulated membrane and setting up bleeding holes, a high degree of simulation of "post-puncture bleeding" can be achieved. At the same time, a fluid supply device can be used to achieve dynamic simulation of different bleeding volumes.

[0013] 2. The drive mechanism and the simulated membrane work together to achieve rapid switching of the puncture area corresponding to the simulated membrane, so as to facilitate repeated training.

[0014] 3. Through the cooperative design of the card block and the sealing slot, an effective seal is formed around the puncture point to prevent simulated blood plasma from seeping out from the edge of the membrane, thus ensuring the reliability of the simulation effect and the cleanliness of the model.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0018] like Figure 1-3 As shown, the present invention provides an oral teaching and training model for pulp blood supply reconstruction, including a model body 1, a puncture seat 3, a simulation membrane 5, a drive mechanism 6, and a liquid supply device 7.

[0019] Specifically, the model body 1 is made of high-strength resin and its appearance simulates the mandibular first molar. In another embodiment, the model body 1 also includes the surrounding alveolar bone and gingival morphology. Inside, there is a puncture channel 2 that simulates a curved root canal. The upper end of the puncture channel 2 is located on the occlusal surface of the crown, and the lower end of the puncture channel 2 extends to the periapical region.

[0020] Furthermore, the puncture seat 3 is fixedly installed at the lower end of the puncture channel 2, and there is a gap between the puncture seat 3 and the puncture channel 2 for the simulated membrane 5 to pass through, and it is positioned corresponding to the external position of the root apex of the tooth. The upper end of the puncture seat 3 is provided with a bleeding hole 4 corresponding to the puncture channel 2, and the bleeding hole 4 is connected to the puncture channel 2. Furthermore, a ring-shaped sealing groove 8 is machined around the circumference of the bleeding hole 4 on the upper surface of the puncture seat 3.

[0021] Furthermore, the simulated film 5 is a thin, highly elastic silicone film, which is horizontally positioned between the lower end of the puncture channel 2 and the bleeding hole 4. The simulated film 5 forms a puncture area corresponding to the overlapping area of ​​the puncture channel 2 and the bleeding hole 4.

[0022] Furthermore, at the lower end of the puncture channel 2, an annular elastic ring 11 made of elastic rubber is provided, and an annular locking block 9 is connected to the elastic ring 11. The shape and position of the locking block 9 correspond to the sealing groove 8. An electromagnet is installed in the puncture seat 3 as a driving source 10, so that the electromagnet can generate magnetic force after being energized, so as to attract the locking block 9 to move downward, thereby causing the locking block 9 to contact the simulated film 5 and press the simulated film 5 into the sealing groove 8. At this time, a seal is formed between the bleeding hole 4 and the simulated film 5. After the locking block 9 moves, the elastic ring 11 is stretched, and after the locking block 9 contacts the sealing groove 8, the seal between the locking block 9 and the puncture channel 2 is maintained. Thus, when the operator punctures the simulated film 5, the simulated blood plasma in the bleeding hole 4 can enter the puncture channel 2 normally without leaking to the outside.

[0023] The drive mechanism 6 is connected to the simulated film 5. The drive mechanism 6 is used to drive the simulated film 5 to move, so as to adjust the puncture area of ​​the simulated film 5 corresponding to the bleeding hole 4. Specifically, the drive mechanism 6 consists of two take-up rollers symmetrically arranged on both sides of the puncture seat 3. The left and right ends of the simulated film 5 are respectively wound on the two take-up rollers 12. The drive mechanism 64 also includes a motor. The output end of the motor is connected to one of the take-up rollers 12 for driving, so as to precisely control the horizontal translation of the simulated film 5 and change the area of ​​the simulated film 5 relative to the bleeding hole 4.

[0024] Furthermore, an absorption mechanism is provided on the side of the puncture seat 3. This absorption mechanism is used to absorb the simulated blood plasma on the surface when the simulated film 5 moves, so as to avoid subsequent entanglement.

[0025] Specifically, the absorption mechanism includes two sponge blocks 13, with one side of each sponge block 13 attached to each other, and the simulated film 5 passing between the two sponge blocks 13, so that the two sponge blocks 13 can be in close contact with the two sides of the simulated film 5, thereby cleaning the simulated blood plasma left on the two sides when the simulated film 5 moves.

[0026] Furthermore, due to the tight adhesion between the sponge block 13 and the simulated film 5, the simulated film 5 is prone to poor adsorption at the initial contact position with the sponge block 13 when it moves, causing simulated blood plasma to drip. Therefore, an arc-shaped groove 14 is cut on the side of the sponge block 13 that contacts the puncture seat 3. The groove 14 can accept and absorb the dripping simulated blood plasma to ensure the cleaning effect of the sponge block 13 on the simulated film 5.

[0027] Furthermore, the fluid supply device 7 includes a storage tank 15 and a fluid supply pump 16. The storage tank 15 stores red simulated blood plasma. The fluid supply pump 16 is specifically a peristaltic pump to ensure fluid supply accuracy. The input end of the fluid supply pump 16 is connected to the storage tank 15, and the output end of the fluid supply pump 16 is connected to the bleeding hole 4 through a pipeline.

[0028] Furthermore, a miniature pressure sensor 17 is embedded in the inner wall of the bleeding hole 4, which is used to sense the pressure inside the bleeding hole 4.

[0029] The operation procedure of the oral teaching and training model for pulp blood supply reconstruction in this embodiment is as follows: During the initialization phase, the electromagnet is energized to attract the card block 9, causing the card block 9 to move down and press against the simulated membrane 5 and the sealing groove 8. The liquid supply pump 16 then delivers simulated plasma into the bleeding hole 4, and the pressure sensor 17 detects the pressure inside the bleeding hole 4. During this phase, the simulated membrane 5 is in a relaxed state, meaning that even if the simulated membrane 5 is punctured, simulated plasma will not leak out.

[0030] During the puncture phase, the infusion pump 16 continues to deliver a small amount of simulated plasma into the bleeding orifice 4. At this time, the pressure inside the bleeding orifice 4 increases, causing the simulated membrane 5 to bulge slightly. The operator then uses a root canal file or a special puncture needle to probe and puncture downwards through the puncture channel 2. When the instrument tip punctures the simulated membrane 5, a breakthrough sensation is felt, and the simulated plasma flows out rapidly after the membrane 5 is punctured. The pressure inside the bleeding orifice 4 drops sharply, which is detected by the pressure sensor 17 to complete the detection of the puncture step. At this time, the infusion pump 16 again slowly delivers a small amount of simulated plasma to the bleeding orifice 4. Through multiple deliveries by the infusion pump 16, a high degree of simulation of the blood outflow posture after puncture is achieved.

[0031] During the reset phase, after a single puncture training is completed, the supply pump 16 re-draws simulated plasma. After the re-drawing is completed, the electromagnet is turned off, and the locking block 9 rebounds and separates from the sealing slot 8 under the action of the elastic ring 11. The motor then drives the take-up roller to rotate, removing the punctured and contaminated simulated film 5 area. The new clean area is moved above the bleeding hole 4, and during the movement, the sponge blocks 13 on both sides automatically wipe the film surface clean.

[0032] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
