Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a precise radiotherapy positioning device for head and neck tumors. Background Art

[0002] During the radiotherapy of head and neck tumors, it is crucial to precisely fix the patient's body position. However, the existing radiotherapy positioning devices have some obvious deficiencies.

[0003] In actual operation, due to the patient's possible involuntary body movement during treatment caused by nervousness, discomfort or other reasons, this leads to inaccurate positioning. Such inaccuracy will directly affect the radiotherapy effect, possibly causing the radiation to fail to accurately irradiate the tumor area, not only reducing the treatment effectiveness but also potentially causing unnecessary damage to the surrounding normal tissues.

[0004] When the existing positioning devices fix the patient, they often fail to fully consider the body type differences of different patients and lack an effective adjustment and adaptation mechanism, thus making it difficult to achieve personalized and precise fixation of the patient. In addition, the existing devices also have problems in terms of the convenience of connection and fixation, with complex operations and time-consuming processes, which affect the treatment efficiency.

[0005] In summary, the existing radiotherapy positioning devices for head and neck tumors need to be improved in terms of the stability, adaptability and operation convenience of fixing the patient to meet the requirements of precise radiotherapy. Summary of the Invention

[0006] In order to overcome the existing problems, the embodiments of the present application provide a precise radiotherapy positioning device for head and neck tumors. This device includes a support assembly, a wrapping assembly and a limiting assembly. The wrapping assembly is arranged above the support assembly and is connected to each other, capable of wrapping the patient. The limiting assembly arranged inside the wrapping assembly passes through the wrapping assembly and is connected to the support assembly, limiting the patient while limiting the wrapping assembly, effectively reducing the problem of inaccurate positioning caused by the patient's involuntary movement, improving the positioning accuracy. Through the coordinated action of the wrapping assembly and the limiting assembly, the adverse impact of the patient's involuntary movement on positioning is effectively suppressed, ensuring that the radiotherapy rays can irradiate the tumor area with high precision, greatly enhancing the treatment effect, reducing the risk of tumor recurrence, and bringing greater hope for the patient's recovery.

[0007] The technical solution adopted by the embodiments of the present application to solve its technical problems is: A precise radiotherapy positioning device for head and neck tumors, including a support component. The support component is made of high-strength medical carbon fiber material with good biocompatibility. Its shape is carefully designed according to the physiological curve of the human head and neck, presenting a certain arc, which can perfectly fit the patient's head and neck, providing stable and comfortable support. An anti-slip pad is provided on the lower surface of the support component to avoid the problem of the support component sliding. A wrapping component is provided above the support component, and the wrapping component is connected to the support component; Among them, a limiting component is provided inside the wrapping component. The wrapping component is made of soft and elastic medical silicone material. The texture of the silicone is delicate, which can closely and gently fit the skin of the patient's head and neck, providing a good wrapping effect. When the wrapping component protects the patient, the limiting component passes through the wrapping component and is connected to the support component. Under the joint limitation of the wrapping component and the limiting component, the patient is limited to avoid position deviation due to shaking. Cover the wrapping component on the patient's head and neck. The soft material of the wrapping component can closely fit the patient's skin, providing an initial fixing and wrapping effect. Then, according to the patient's body type and possible shaking situation, select a suitable limiting hole and insert the limiting rod of the limiting component into it. At this time, the connecting column and the protection plate contact the protection net, and through the connection of the limiting rod and the support component, further limitation of the patient is achieved.

[0008] Preferably, the limiting component includes a limiting rod. A connecting column is provided above the limiting rod. A protection plate is provided on the outer wall of the connecting column. A limiting column is provided at the bottom end of the limiting rod. The limiting rod in the limiting component is made of durable stainless steel material, and the surface is treated with rust prevention to ensure that it is not easy to rust and damage during long-term use. The connecting column and the protection plate are made of lightweight and durable engineering plastic material, having a certain toughness and strength. When the limiting column at the bottom end of the limiting rod is connected to the limiting hole, the connecting column and the protection plate above contact the protection net, so that the limiting component contacts the protection net for limitation.

[0009] Preferably, the support component includes a base. The surface of the base is specially treated, having anti-slip and sweat-absorbing functions, ensuring the patient's stability during the treatment process. A head pad is provided on the upper surface of the base at the bottom end of the through hole. Through the setting of the head pad, the patient's head can be better supported. A limiting plate is provided around the base. The size of the base is the same as that of the wrapping component. When the wrapping component corresponds to the base, the limiting plate limits the wrapping component.

[0010] Preferably, a number of limiting holes are provided inside the base. The size of the limiting holes is the same as that of the limiting column. By changing the connection between the limiting column and the limiting holes at different positions, the positional relationship of the limiting component can be changed, so as to adapt to different patients.

[0011] Preferably, the wrapping component includes side plates, and a protective net is arranged inside the side plates. The shape of the protective net is the same as that of the side plates. The protective net has good air permeability, and a through hole is formed at one end of the protective net.

[0012] Preferably, a plurality of connecting pieces are arranged at the periphery of the side plates. A plurality of connecting holes are formed at the corresponding positions on the upper surface of the base. When the wrapping component corresponds to the supporting component, the connecting pieces inside the wrapping component are connected to the connecting holes inside the supporting component at this time.

[0013] The advantages of the embodiments of the present application are as follows: 1. The device of the present application includes a supporting component, a wrapping component and a limiting component. The wrapping component is arranged above the supporting component and connected to each other, and can wrap a patient. The limiting component arranged inside the wrapping component passes through the wrapping component and is connected to the supporting component. While limiting the wrapping component, the patient is also limited, effectively reducing the problem of inaccurate positioning caused by the involuntary shaking of the patient, improving the accuracy of positioning. Through the synergistic effect of the wrapping component and the limiting component, the adverse impact of the involuntary shaking of the patient on the positioning is effectively suppressed, ensuring that the radiotherapy rays can irradiate the tumor area with high precision, greatly enhancing the treatment effect, reducing the risk of tumor recurrence, and bringing greater hope for the recovery of the patient.

[0014] 2. The limiting component is composed of a limiting rod, a connecting column and a protective plate. The limiting rod is connected to a plurality of limiting holes inside the supporting component. By changing the connection of the limiting rod to different limiting holes, the position of the limiting component can be flexibly adjusted. The adjustable limiting component can flexibly adjust the position according to the body type differences of different patients. Whether it is a patient with a petite build or a patient with a relatively burly build, they can all be fixed just right, thereby broadening the application range of the device and meeting the needs of various patients.

[0015] 3. A limiting plate is arranged on the outer side of the supporting component. When the wrapping component corresponds to the supporting component, the wrapping component is limited by the limiting plate, making the connection between the supporting component and the wrapping component more convenient and fast, significantly shortening the treatment preparation time, enabling more efficient utilization of medical resources, and increasing the number of patients received by the hospital.

[0020] Embodiments of the present application provide a precise radiotherapy positioning device for head and neck tumors to solve the problems in the prior art. The device includes a support assembly, a wrapping assembly, and a limiting assembly. The wrapping assembly is arranged above the support assembly and connected to each other, capable of wrapping the patient. The limiting assembly arranged inside the wrapping assembly passes through the wrapping assembly and is connected to the support assembly, limiting the patient while limiting the wrapping assembly, effectively reducing the problem of inaccurate positioning caused by the involuntary shaking of the patient, improving the accuracy of positioning. Through the synergistic effect of the wrapping assembly and the limiting assembly, the adverse impact of the involuntary shaking of the patient on positioning is effectively suppressed, ensuring that the radiotherapy rays can irradiate the tumor area with high precision, greatly enhancing the treatment effect, reducing the risk of tumor recurrence, and bringing greater hope for the patient's recovery. The limiting assembly is composed of a limiting rod, a connecting column, and a protective plate. The limiting rod is connected to multiple limiting holes inside the support assembly. By changing the connection between the limiting rod and different limiting holes, the position of the limiting assembly can be flexibly adjusted. The adjustable limiting assembly can flexibly adjust the position according to the body type differences of different patients. Whether it is a patient with a petite build or a patient with a more burly build, they can be properly fixed, thus broadening the application range of the device and meeting the needs of various patients. The outer side of the support assembly is provided with a limiting plate. When the wrapping assembly corresponds to the support assembly, the wrapping assembly is limited by the limiting plate, making the connection between the support assembly and the wrapping assembly more convenient and fast, significantly shortening the treatment preparation time, enabling more efficient utilization of medical resources, and increasing the hospital's patient reception volume.

[0021] The technical solutions in the embodiments of the present application for solving the above problems are generally as follows: Embodiment 1 This embodiment gives the specific structure of a precise radiotherapy positioning device for head and neck tumors, as Figures 1-4 shown, including a support assembly 1. The support assembly 1 is made of high-strength medical carbon fiber material with good biocompatibility. Its shape is carefully designed according to the physiological curve of the human head and neck, presenting a certain arc to perfectly fit the patient's head and neck, providing stable and comfortable support. The lower surface of the support assembly 1 is provided with an anti-slip pad to avoid the problem of the support assembly 1 sliding. Above the support assembly 1 is provided with a wrapping assembly 2, and the wrapping assembly 2 is connected to the support assembly 1; Among them, a limiting component 3 is arranged inside the wrapping component 2. The wrapping component 2 is made of soft and elastic medical silicone material. The texture of the silicone is delicate, which can closely and gently fit the head and neck skin of the patient, providing a good wrapping effect. When the wrapping component 2 protects the patient, the limiting component 3 passes through the wrapping component 2 and is connected to the support component 1. Under the joint limitation of the wrapping component 2 and the limiting component 3, the patient is limited to avoid position deviation due to shaking. Cover the wrapping component 2 on the head and neck of the patient. The soft material of the wrapping component 2 can closely fit the patient's skin, providing a preliminary fixing and wrapping function. Then, according to the patient's body type and possible shaking situation, select a suitable limiting hole 13 and insert the limiting rod 31 of the limiting component 3 into it. At this time, the connecting column 34 and the protection plate 33 are in contact with the protection net 22. Through the connection of the limiting rod 31 and the support component 1, further limitation of the patient is achieved.

[0022] The limiting component 3 includes a limiting rod 31. A connecting column 34 is arranged above the limiting rod 31. A protection plate 33 is arranged on the outer wall of the connecting column 34. A limiting column 32 is arranged at the bottom end of the limiting rod 31. The limiting rod 31 in the limiting component 3 is made of durable stainless steel material and its surface is treated with rust prevention to ensure that it is not easy to rust and damage during long-term use. The connecting column 34 and the protection plate 33 are made of lightweight and durable engineering plastic material, with a certain toughness and strength. When the limiting column 32 at the bottom end of the limiting rod 31 is connected to the limiting hole 13 and the connecting column 34 and the protection plate 33 above are in contact with the protection net 22, the limiting component 3 is in contact with the protection net 22 for limitation.

[0023] The support component 1 includes a base 11. The surface of the base 11 is specially treated, with anti-slip and sweat-absorbing functions, ensuring that the patient remains stable during the treatment process. A head pad 4 is arranged on the upper surface of the base 11 at the bottom end of the through hole 23. Through the setting of the head pad 4, the patient's head can be better supported. A limiting plate 12 is arranged around the base 11. The size of the base 11 is the same as that of the wrapping component 2. When the wrapping component 2 corresponds to the base 11, the limiting plate 12 limits the wrapping component 2.

[0024] A number of limiting holes 13 are arranged inside the base 11. The size of the limiting holes 13 is the same as that of the limiting column 32. By changing the connection of the limiting column 32 to the limiting holes 13 at different positions, the positional relationship of the limiting component 3 can be changed, so as to adapt to different patients.

[0025] The wrapping component 2 includes side plates 21. A protection net 22 is arranged inside the side plates 21. The shape of the protection net 22 is the same as that of the side plates 21. The protection net 22 has good air permeability. A through hole 23 is opened at one end of the protection net 22.

[0026] There are several connecting pieces 24 provided around the side plate 21. At the corresponding positions on the upper surface of the base 11, there are several connecting holes 14. When the wrapping assembly 2 corresponds to the support assembly 1, the connecting pieces 24 inside the wrapping assembly 2 are connected to the connecting holes 14 inside the support assembly 1 at this time.

[0027] By adopting the above technical solution: In a specialized tumor hospital, a middle-aged patient with head and neck tumors is about to receive radiotherapy.

[0028] Medical staff use the positioning device of the present invention to position the patient. After the patient lies on the support assembly 1, the medical staff cover the wrapping assembly 2 well. According to the patient's body type, a suitable limiting hole 13 is selected to insert the limiting rod 31. Through the limiting plate 33, the connection between the wrapping assembly 2 and the support assembly 1 is quickly completed. When the wrapping assembly 2 corresponds to the support assembly 1, the limiting plate 12 can make the wrapping assembly 2 quickly and accurately snap into the predetermined position, effectively limit and fix the wrapping assembly 2. During the entire radiotherapy process, the patient's head and neck remain stable, the positioning is accurate, and the radiotherapy proceeds smoothly with good treatment effects.

[0029] Embodiment 2 This embodiment provides a specific structure of a precise radiotherapy positioning device for head and neck tumors, as Figures 1-4 shown, including a support assembly 1. The support assembly 1 is made of high-strength medical carbon fiber material with good biocompatibility. Its shape is carefully designed according to the physiological curve of the human head and neck, presenting a certain arc to perfectly fit the patient's head and neck, providing stable and comfortable support. The lower surface of the support assembly 1 is provided with an anti-slip pad to avoid the problem of the support assembly 1 sliding. Above the support assembly 1 is provided a wrapping assembly 2, and the wrapping assembly 2 is connected to the support assembly 1; Among them, a limiting assembly 3 is provided inside the wrapping assembly 2. The wrapping assembly 2 is made of soft and elastic medical silicone material. The texture of the silicone is delicate, which can closely and gently fit the skin of the patient's head and neck, providing a good wrapping effect. When the wrapping assembly 2 protects the patient, the limiting assembly 3 passes through the wrapping assembly 2 and is connected to the support assembly 1. Under the joint limitation of the wrapping assembly 2 and the limiting assembly 3, the patient is limited to avoid position deviation due to shaking. The wrapping assembly 2 is covered on the patient's head and neck. The soft material of the wrapping assembly 2 can closely fit the patient's skin, providing a preliminary fixing and wrapping effect. Then, according to the patient's body type and possible shaking conditions, a suitable limiting hole 13 is selected, and the limiting rod 31 of the limiting assembly 3 is inserted into it. At this time, the connecting column 34 and the protection plate 33 are in contact with the protection net 22. Through the connection of the limiting rod 31 with the support assembly 1, further limitation of the patient is achieved.

[0030] The limiting component 3 includes a limiting rod 31. Above the limiting rod 31, there is a connecting column 34. On the outer wall of the connecting column 34, there is a protective plate 33. At the bottom end of the limiting rod 31, there is a limiting column 32. The limiting rod 31 in the limiting component 3 is made of durable stainless steel and its surface is treated against rust to ensure that it is not prone to rusting and damage during long-term use. The connecting column 34 and the protective plate 33 are made of lightweight and durable engineering plastic materials, which have a certain toughness and strength. When the limiting column 32 at the bottom end of the limiting rod 31 is connected to the limiting hole 13, and the connecting column 34 and the protective plate 33 above are in contact with the protective net 22, the limiting component 3 contacts the protective net 22 for limiting.

[0031] The supporting component 1 includes a base 11. The surface of the base 11 is specially treated to have anti-slip and sweat-absorbing functions to ensure that the patient remains stable during the treatment process. On the upper surface of the base 11, at the bottom end of the through hole 23, there is a head pad 4. Through the setting of the head pad 4, the patient's head can be better supported. There is a limiting plate 12 around the base 11. The size of the base 11 is the same as that of the wrapping component 2. When the wrapping component 2 corresponds to the base 11, the limiting plate 12 limits the wrapping component 2.

[0032] Inside the base 11, there are several limiting holes 13. The size of the limiting holes 13 is the same as that of the limiting column 32. By changing the connection between the limiting column 32 and the limiting holes 13 at different positions, the positional relationship of the limiting component 3 can be changed, so as to adapt to different patients.

[0033] The wrapping component 2 includes side plates 21. Inside the side plates 21, there is a protective net 22. The shape of the protective net 22 is the same as that of the side plates 21. The protective net 22 has good air permeability. One end of the protective net 22 is provided with a through hole 23.

[0034] There are several connecting pieces 24 around the side plates 21. At the corresponding positions on the upper surface of the base 11, there are several connecting holes 14. When the wrapping component 2 corresponds to the supporting component 1, at this time, the connecting pieces 24 inside the wrapping component 2 are connected to the connecting holes 14 inside the supporting component 1.

[0035] By adopting the above technical solutions: In the radiotherapy department of a large general hospital, an elderly patient with head and neck tumors used this device.

[0036] Since the patient is relatively thin, the medical staff adjusts the position of the limiting component 3 to make it closely fit the patient's head and neck. According to the patient's body shape and swaying situation, a suitable limiting hole 13 on the supporting component 1 is selected, and the limiting rod 31 is accurately inserted and fixed. At this time, the limiting rod 31 exerts appropriate pressure on the patient through the connecting column 34 and the protection plate 33 to limit its swaying. During radiotherapy, although the patient was initially a bit nervous, the device effectively limited his involuntary swaying, ensuring the accuracy of radiotherapy, and the patient was also satisfied with the comfort of the treatment process.

[0037] The working principle is as follows: First of all, the patient lies flat on the supporting component 1, and the head and neck fit the shape of the supporting component 1 to obtain basic support.

[0038] Then, the wrapping component 2 is covered on the patient's head and neck. The soft material of the wrapping component 2 can closely fit the patient's skin to provide preliminary fixation and wrapping. Then, according to the patient's body shape and possible swaying situation, a suitable limiting hole 13 is selected, and the limiting rod 31 of the limiting component 3 is inserted into it. At this time, the connecting column 34 and the protection plate 33 contact the protection net 22, and through the connection between the limiting rod 31 and the supporting component 1, further limitation of the patient is achieved.

[0039] In this process, the limiting plate 12 on the outer side of the supporting component 1 plays a role in positioning and fixing the wrapping component 2 to ensure the accurate and stable connection between the wrapping component 2 and the supporting component 1.

[0040] Through the coordinated action of the above-mentioned components, the involuntary swaying of the patient's head and neck is effectively limited, thereby realizing accurate radiotherapy positioning and ensuring the accuracy and effectiveness of radiotherapy.

[0041] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
