Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an inflatable mouthpiece used for oral cancer radiotherapy. Background Art

[0002] The inflatable mouthpiece is an innovative auxiliary tool designed for oral cancer patients undergoing radiotherapy, aiming to improve the accuracy and comfort of radiotherapy. The mouthpiece is made of medical-grade silicone material, has good biocompatibility and flexibility, and can be individually adjusted according to the patient's oral morphology. Through the inflatable device, the mouthpiece can form a stable support structure in the mouth, effectively fix the tongue and cheek, reduce the exposure of healthy tissue during radiotherapy, and thus reduce the risk of side effects.

[0003] The inflatable mouthpiece for oral cancer radiotherapy in the prior art can open the patient's mouth during use, making it easier for medical staff to perform oral treatment operations. However, most traditional inflatable mouthpieces are integral airbag structures when in use, which takes up a large space and is not conducive to the operation of medical staff.

[0004] When applying for the present invention, the applicant found through search that a Chinese patent disclosed an "inflatable mouthpiece for oral cancer radiotherapy", and its application number is "202010521748.1". This patent mainly records the scale and inflation capacity of the tongue depressor, which can be used for position confirmation each time to ensure positioning repeatability. In addition, the drainage side holes on both sides of the tongue depressor can also effectively absorb saliva to keep the patient's mouth clean and comfortable, but the tongue depressor is large in size, which will reduce the surgical space in the mouth, so it may be inconvenient for medical staff to operate. Therefore, according to the applicant's invention, an inflatable mouthpiece for oral cancer radiotherapy was invented, which solves the problem that most traditional inflatable mouthpieces are integral airbag structures when in use, which will cause a large space to be occupied and is not conducive to the operation of medical staff. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment:

[0033] Such as Figure 1-7As shown in the figure, an inflatable mouthpiece for radiotherapy of oral cancer provided by an embodiment of the present invention includes: a lower support dental brace 1 and an upper support dental brace 2. The upper surface of the lower support dental brace 1 is provided with the upper support dental brace 2. Open slots 104 are provided at both front ends between the lower support dental brace 1 and the upper support dental brace 2. Through the setting of the open slots 104, it is convenient to rotate the support rod 703, complete the angular expansion, and rotate and support at different angles. A rotating rod is fixedly connected inside the open slot 104. A support rod 703 is arranged inside the open slot 104. The support rod 703 plays a supporting role, pushing and supporting the upper support dental brace 2 and the lower support dental brace 1 around the rotating shaft 3 to expand the patient's oral cavity, facilitating subsequent treatment operations of medical staff on oral cancer. A through hole 701 is provided at the end of the support rod 703. Through the sleeving of the through hole 701 and the rotating rod, the rotating function is realized. The through hole 701 and the rotating rod are sleeved and matched. A buffer sleeve 7 is sleeved between the support rods 703. Through the buffer sleeve 7, the support of the support rod 703 can be achieved, facilitating the support and compression effects. An airbag 702 is fixedly connected between the support rods 703 inside the buffer sleeve 7. Through the elastic support of the airbag 702, the support and compression effects on the support rod 703 can be achieved. Concave grooves 101 are provided on the upper and lower surfaces of the lower support dental brace 1 and the upper support dental brace 2. Through the setting of the concave grooves 101, the patient's teeth can be cooperated to achieve firm contact, increasing stability and making it not easy to shake and loosen. The patient wears the lower support dental brace 1 and the upper support dental brace 2, and then cooperates with the teeth through the concave grooves 101. When the tooth spacing of different people is different, the spacing between the lower support dental brace 1 and the upper support dental brace 2 can be adjusted by support. A plurality of support springs 103 are fixedly connected inside the concave grooves 101. Through the elastic support provided by the support springs 103, a buffering effect is achieved during the patient's tooth biting process, increasing the comfort of use. The top of the support spring 103 is fixedly connected with a buffer plate 102, and the buffer plate 102 is made of rubber material. When the patient needs to swallow, by compressing the buffer plate 102, the support spring 103 elastically returns, which can facilitate the patient's swallowing action;

[0034] There is a regulating screw 402 rotatably connected between the upper supporting dental appliance 2 and the lower supporting dental appliance 1. Through the threaded fit between the regulating screw 402 and the threaded sleeve 4, the threaded movement can be realized. There is a threaded sleeve 4 threadedly connected between the regulating screws 402. Through the setting of the threaded sleeve 4, the threaded recovery and threaded extension with the regulating screw 402 can be completed, facilitating the precise adjustment of the spacing during use. The convex block 502 meshes with the tooth groove 401. Subsequently, the tooth groove 401 rotates, and after rotation, it drives the threaded sleeve 4 to rotate. Since the threads on both sides inside the threaded sleeve 4 are reverse threads, the regulating screw 402 connected and matched with the internal thread will extend bidirectionally at both ends, supporting and expanding the upper supporting dental appliance 2 and the lower supporting dental appliance 1, and enabling accurate cooperation with the patient's teeth. There is a tooth groove 401 provided in the middle of the threaded sleeve 4, and the two regulating screws 402 on both sides have reverse threads. The threaded structures of the regulating screws 402 between the lower supporting dental appliance 1 and the upper supporting dental appliance 2 are oppositely arranged. There is a regulating rod 501 provided between the two tooth grooves 401. Convex blocks 502 are fixedly connected to both the upper and lower sides of the regulating rod 501. Through the meshing of the convex block 502 and the tooth groove 401, the rotation of the tooth groove 401 can be achieved, and the convex block 502 meshes with the tooth groove 401. One end of the regulating rod 501 is fixedly connected to a hand-held rod 5. Medical staff can horizontally insert one end of the regulating rod 501 between the tooth grooves 401 through the hand-held rod 5, and by pulling the hand-held rod 5. Moreover, the end of the hand-held rod 5 is flat-shaped. Through this flat-shaped setting, it is convenient to hold. Fixed plates are fixedly connected to the rear ends of both the lower supporting dental appliance 1 and the upper supporting dental appliance 2. A rotating shaft 3 passes through between the fixed plates. Through the rotating shaft 3, the rotation can be coordinated, facilitating the adjustment of the angle during rotation;

[0035] A flow-through pipe 6 is fixedly connected to the middle part of the inner side of the lower brace 1. A number of sputum suction covers 601 are fixedly connected to the bottom end of the flow-through pipe 6. Sputum is sucked out through the sputum suction covers 601 and flows through the flow-through pipe 6 to the sputum suction tube 802, which facilitates the discharge of sputum, can reduce the number of times the patient swallows saliva, and discharges the sputum, facilitating the medical staff to perform oral treatment operations. A corrugated pipe 602 is fixedly connected between the flow-through pipes 6. Through the setting of the corrugated pipe 602, it can correspond to the stretching effect of the braces on both ends of the flow-through pipe 6 and the corrugated pipe 602. A flow-through branch pipe 8 is fixedly connected to the middle part of the front side of the lower brace 1. Through the flow-through branch pipe 8, it is convenient for the separate flow of gas and liquid and reduces the clutter of pipelines. A sputum suction tube 803 is fixedly connected to one side inside the flow-through branch pipe 8, and a trachea 801 is fixedly connected to the other side inside the flow-through branch pipe 8. Through the trachea 801, it is convenient to fill gas to support the airbag 702 and for exhaust. One end of the trachea 801 is fixedly connected to the airbag 702, one end of the sputum suction tube 803 is fixedly connected to the flow-through pipe 6, the end of the sputum suction tube 803 away from the flow-through pipe 6 is fixedly connected to a sputum discharge pipe 804, and the end of the trachea 801 away from the airbag 702 is fixedly connected to a pump body 802. Driven by the pump body 802, external gas is inhaled and flows through the trachea 801 into the inside of the airbag 702, thereby playing a supporting role for the support rod 703.

[0036] Working principle: When in use, the patient wears the lower brace 1 and the upper brace 2. Then, it is fitted with the teeth through the concave groove 101. When the tooth spacing of different people is adjustable by supporting and adjusting the spacing between the lower brace 1 and the upper brace 2. At this time, the medical staff can horizontally insert one end of the adjusting rod 501 between the tooth grooves 401 through the handheld rod 5. By pulling the handheld rod 5, the convex block 502 meshes with the tooth groove 401 after pulling. Then, the tooth groove 401 rotates, driving the threaded sleeve 4 to rotate. Since the threads on both sides inside the threaded sleeve 4 are reverse threads, the adjusting screw 402 connected and fitted with the internal threads will extend bidirectionally at both ends, supporting and expanding the upper brace 2 and the lower brace 1, and being able to accurately fit with the patient's teeth. And because the threaded sleeves 4 between the lower brace 1 and the upper brace 2 are arranged with reverse threads, when the handheld rod 5 is pulled, the same extension and retraction effects can be achieved for the upper and lower tooth grooves 401. The length of the adjusting rod 501 can be controlled according to the usage situation, such as 1 - 2 cm, to prevent damage to the patient's oral cavity during the insertion process. After the adjustment is completed, the handheld rod 5 is taken out. At this time, it can be driven by the pump body 802 to inhale external gas, and the gas flows through the trachea 801 into the inside of the airbag 702, thus playing a supporting role for the support rod 703, supporting and pushing open the upper brace 2 and the lower brace 1 around the rotating shaft 3, completing the expansion of the patient's oral cavity, and facilitating the subsequent treatment operations of the medical staff for oral cancer. During the treatment process, there will be sputum in the patient's oral cavity. At this time, the sputum suction device can be fixed to the sputum outlet pipe 804, and then the sputum is sucked out through the sputum suction cover 601 and flows through the circulation pipe 6 to the sputum suction pipe 802, facilitating the discharge of the sputum. Then, when the patient needs to swallow, by compressing the buffer plate 102, the support spring 103 elastically returns, which can facilitate the patient's swallowing action.
