Description

[Technical Field]

[0001] The present invention relates to the field of nuclear medicine external radiation therapy, and in particular to a beta radiation therapy device and method of use thereof. [Background technology]

[0002] β-rays emitted from radionuclides can be used to effectively treat various skin diseases, especially cutaneous hemangiomas and keloids. For treatment, the β-ray applicator must be placed in close contact with the surface of the lesion.

[0003] Currently, there are two types of beta ray applicators in common use: the first type is a small dose applicator; 32 Although the P applicator can be taken home by the patient after application, there are problems such as slippage, falling off, insufficient protection, loss, and environmental pollution. For example, the Chinese utility model patent with registration disclosure number CN212416081U is for radioactive nuclides. 32 The present invention discloses an applicator based on P, which includes a carrier and a base that can be snapped onto the carrier, and a carrier layer for carrying a drug is provided on the top of the carrier, and the carrier can be closely attached to the lesion area. 32 Although the problems of the P applicator's lack of radiation protection and poor adhesion have been solved, to achieve the above goals, the sealing layer, carrier layer, base layer, and base are all 3D printed, and are printed after 3D scanning and data analysis of the lesion morphology. Therefore, this solution needs to be individually tailored to each lesion area and cannot be universally adjusted.

[0004] The second type is a fixed-shape, fixed-dose 90 Sr- 90 It is a Y applicator and cannot provide different doses of beta-ray therapy depending on the shape, thickness, and condition of the lesion. For example, the Chinese patent with application disclosure number CN102049098A 90This patent discloses a strontium applicator, which includes a handle and a protective screen, a groove in the center of the handle, an applicator at the bottom, and a clamping bead and spring on the protective screen, which is placed in the groove at the bottom of the handle and can be fixed by the clamping bead. The purpose of this solution is to make the protective screen detachable, which facilitates operation and reduces radiation exposure time, but in practice, it does not solve the problem that this type of applicator cannot be adjusted to fit its shape.

[0005] As described above, current applicators cannot be adapted to shapes, have poor adaptability, or must be adapted using a 3D printer, making it impossible to use the same device to adapt to different lesion shapes, thicknesses, conditions, etc., and therefore lack versatility and adjustability.

[0020] The following provides a clear and complete description of the technical solutions in the embodiments of the present invention with accompanying drawings, but it is clear that the described embodiments are only some of the embodiments of the present invention and do not represent all of the embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without any creative work fall within the scope of protection of the present invention.

[0021] The object of the present invention is to provide a beta ray therapy device and a method for using the same that solves the problems existing in the prior art described above. By moving the shape-conforming pieces on the shape-conforming frame to different positions, shape-conforming areas of different shapes can be formed according to the different shapes of the treatment target areas. The beta rays emitted by the beta ray source are then irradiated onto the treatment target area through the shape-conforming area, thereby allowing the same treatment device to be used to treat treatment target areas of different shapes, thereby providing versatility and adjustability.

[0022] In order to make the above objects, features and advantages of the present invention more clear and understandable, the present invention will be described in more detail below with reference to the drawings and specific embodiments.

[0023] As shown in Figures 1 to 8, the present invention provides a beta ray therapy device, which includes a therapy device body and a shape-conforming structure, where the therapy device body is mainly used to irradiate beta rays, and the shape-conforming structure is used to limit the irradiation range of beta rays. Specifically, the therapy device body includes a beta ray source 3 and a beta ray shielding structure 2, and the beta ray shielding structure 2 is provided with a mounting cavity and a window communicating with the mounting cavity. The beta ray source 3 is installed in the mounting cavity, and the beta ray source 3 is: 90 Sr- 90 Sealed source of Y, 32β-ray shielding structures (2) can be made of lightweight materials such as aluminum, resin, or plastic. They are used to shield radiation emitted from the β-ray source in directions other than the lesion, protecting surrounding people. The conformable structure includes a conformable frame (6) and multiple conformable pieces (7). A transparent area for β-rays is defined in the center of the conformable frame (6). The conformable pieces (7) are attached to the conformable frame (6). Handles are attached to the ends of the conformable pieces (7) away from the conformable frame (6). The handles can be used to pull or push the conformable pieces (7) toward or away from the transparent area, thereby adjusting the area and position of the shielded transparent area. When multiple conformable pieces (7) are present, the lengths of the different conformable pieces (7) within the transparent area can be adjusted (i.e., the shielding areas and positions can be varied). The positions of the conformable pieces (7) can be adjusted according to the shape of the area to be treated, forming a conformable area surrounding the area to be treated within the transparent area. The shape of the conformable area is approximately the same as the shape of the area to be treated. The more shape-conforming pieces 7 there are and the smaller their sizes, the finer the shape-conforming region can be achieved. However, the specifications and size of the shape-conforming pieces 7 are not limited. The shape of the beta-ray shielding structure 2 and the shape of the window are not particularly limited and may be circular, rectangular, or other shapes. The window opening range can cover the area of ​​the treatment target, so after adjusting the shape-conforming region, the treatment target can be covered. The beta-ray source 3 emits beta-rays within the mounting cavity, which pass through the window and are emitted toward the shape-conforming region, thereby irradiating and treating the lesion. As described above, the present invention can form shape-conforming regions of different shapes according to different shapes of treatment target regions by moving the shape-conforming pieces 7 on the shape-conforming frame 6 to different positions. Then, the beta-rays emitted by the beta-ray source 3 irradiate the treatment target region through the shape-conforming region. This allows the same treatment device to be used to accommodate different shapes of treatment target regions, resulting in versatility and adjustability.

[0024] 7 and 8, the conformal frame 6 may be an annular frame, the main body of which is annular (the term "annular" here refers to a rectangular, circular, or other shape that can form a ring, and does not specifically refer to a circular ring), the hollow area of ​​the annular frame being the transparent area, and the multiple conformal pieces 7 being divided into two sets, each set including multiple parallel conformal pieces 7, the two sets of shape conformal pieces 7 being slidably disposed on opposite sides of the annular frame, and the shape and area of ​​the blocked area of ​​the transparent area can be changed by relatively inserting or removing the shape conformal pieces 7. Alternatively, the conformal frame 6 may be a rectangular frame as shown in FIG. 8, the shape conformal pieces 7 being elongated rectangular sheets, the two sets of rectangular sheets being located on opposite sides of the rectangular frame.

[0025] As shown in Figures 1, 3, 7 and 8, a plurality of first fastening buckles 8 are provided on the outer periphery of the beta ray shielding structure 2, and a plurality of second fastening buckles 11 are provided on the outer periphery of the form-fitting frame 6, the first fastening buckles 8 and the second fastening buckles 11 are spaced apart, with at least two on each side, and the first fastening buckles 8 and the second fastening buckles 11 are each configured to be connected to an elastic bandage, which fixes the treatment device to the human body via the elastic bandage, thereby fixing the form-fitting structure and the treatment device body respectively and realizing secondary fixation, which improves the fixing effect, better fixes the treatment device, and prevents the treatment device from being misaligned and affecting the radiation effects.

[0026] As shown in FIGS. 1 and 4 , the beta ray therapy device includes a beta ray radiation window, which is installed in a window of a beta ray shielding structure 2. The beta ray radiation window includes one or more shielding pieces 4, which are made of a lightweight material such as aluminum, resin, or plastic. The shielding pieces 4 may be installed directly through the beta ray shielding structure 2, or may be installed in the window structure and attached to the window through the window structure. When the shielding pieces 4 move relative to the window, they can move horizontally or vertically, preferably using a vertical movement method for insertion or withdrawal. A handle can be installed on one end of the shielding pieces 4 away from the beta ray shielding structure 2, and the handle can be used to guide the movement of the shielding pieces 4. When the therapy device main body is not performing irradiation, the shielding pieces 4 can completely seal the window, preventing accidental beta ray irradiation. When only one shielding piece 4 is provided, the size of the window can be changed by moving the shielding piece 4 back and forth in one direction. When multiple shielding pieces 4 are provided, the size of the window can be changed to match the shape of the treatment area by moving different shielding pieces 4. By changing the window, the irradiation range of the beta rays emitted from the beta ray source 3 can be adjusted. Thus, based on forming a shape-conforming area using an existing shape-conforming structure, the present invention forms a two-stage adjustment method to adjust the irradiation range of beta rays, more accurately control the beta rays, irradiate the treatment area, reduce the amount of irradiation to non-lesion areas, and better protect normal tissue.

[0027] Specifically, the beta ray shielding structure 2 may have a through hole or groove, and the shielding piece 4 may be drilled into the through hole or groove, and may move toward or away from the window to shield or open the window.

[0028] When multiple shielding pieces 4 are installed, the multiple shielding pieces 4 are divided into two sets, each set including multiple shielding pieces 4 arranged in parallel, and the two sets of shielding pieces 4 are slidably arranged on opposite sides of the beta ray shielding structure 2. When a rectangular frame is used as the beta ray shielding structure 2, rectangular sheets are used as the shielding pieces 4, and the rectangular sheets are installed on opposite sides of the rectangular frame.

[0029] Two sets of shielding pieces 4 are installed in a one-to-one correspondence to form multiple pairs, one of the shielding pieces 4 in each pair having a V-shaped protrusion and the other having a V-shaped groove that matches the V-shaped protrusion, the V-shaped protrusion and the V-shaped groove extending in the direction of the expanding area of ​​the window. When the shielding pieces 4 are close to each other, the V-shaped protrusion is inserted into the V-shaped groove to form upper and lower shielding, reducing the gap and improving the beta ray shielding effect.

[0030] As shown in Figures 1 and 2, the beta ray therapy device includes a control unit 1, which is attached to the outside of a beta ray shielding structure 2, and which includes a display unit 9, operation buttons 10, a dose measurement unit, and a notification unit or alarm unit. The dose measurement unit is used to measure the radiation dose received by the lesion site, the display unit 9 is used to display the measured radiation dose received by the lesion site, and when the required dose or time is about to be reached, a notification sound or alarm can be emitted through the notification unit or alarm unit, and the operation buttons 10 can control the operation of the control unit 1, such as starting, stopping, and setting the value of the notification dose.

[0031] As shown in Figures 5, 6, 9, and 10, the beta ray therapy device includes a support device, which includes a base 5, a host 14, and a robotic arm 13. The base 5 has a groove in which the therapy device body is placed, and can support the therapy device body when the therapy device is idle. The robotic arm 13 is fixedly attached to the host 14, which supports the movement of the robotic arm 13. The host 14 also has a sealed storage area 15, which can be used to store the base 5 and the conformable structure, as well as the therapy device body, and both the base 5 and the conformable structure can be arranged laterally within the sealed storage area 15.

[0032] The robot arm 13 is provided with a clamp 12 for clamping the treatment device body. By installing the robot arm 13 and the clamp 12, the treatment device body can be moved to the treatment target area using the robot arm 13 and held in the corresponding position for irradiation. Meanwhile, the treatment device body can be returned to the sealed storage area 15 after use.

[0033] When using the device of the present invention to treat proliferative diseases such as scars, hemangiomas, tumors, and localized scleroderma, the position of the shielding piece 4 can be adjusted to obtain beta-ray irradiation windows with different opening sizes, and the shape-conforming piece 7 can be adjusted to obtain shape-conforming areas with different opening sizes, allowing the application shape to be selected according to the shape, thickness, and condition of the lesion, thereby adjusting the irradiation range of the beta-ray source 3. The treatment device body and the shape-conforming structure can be fixed to the surface of the human body via an elastic bandage, making them less likely to fall off. The treatment position of the treatment device can be fixed using the clamp 12 and robotic arm 13, and the treatment device can be stored in the sealed storage area 15, making it convenient to use and retrieve.

[0034] As shown in FIGS. 1 to 10, the present invention further provides a method for applying the above-mentioned beta ray therapy device, which includes the following contents: The shape-conforming frame 6 is placed on the area to be treated and fixed using the second fastening buckle 11 and an elastic bandage, and the position of the shape-conforming piece 7 is adjusted according to the shape of the area to be treated to form a shape-conforming area surrounding the area to be treated, thereby achieving a shape adjustment effect.

[0035] A burn plaster, scar plaster or gel is applied to the area to be treated, and uneven lesions are applied horizontally, with the area after application being placed so that it is approximately flush with the surface of the shape-matching piece 7. Areas with thicker lesions (thinner application thickness) can receive a higher radiation dose, and areas with thinner lesions (thicker application thickness) can receive a lower radiation dose, allowing lesions of different degrees to be irradiated with different intensities, thereby achieving the effect of intensity modulation.

[0036] The treatment device body can be snapped onto the shape-conforming frame 6 and clamped with the robotic arm 13, or secured using the first fastening buckle 8 and an elastic bandage, and a beta-ray source is used to emit beta-rays, which pass through the shape-conforming area and irradiate the area after application.

[0037] To better illustrate how to use the present invention, the following specific examples are provided. When a patient has a scar on their forearm that requires treatment, the radiation dose required for treatment is calculated based on the size of the scar and set as the notification threshold of the control unit 1. The position of the shielding piece 4 is adjusted to adjust the shape of the beta-ray irradiation window to match the shape of the scar. The shape-conforming structure is used to surround the scar area and fixed with an elastic bandage. The shape-conforming piece 7 is adjusted to form a shape-conforming area that is approximately the same shape and size as the scar. Gel is used to create a flat surface on the uneven scar area. After that, the treatment device main body is fixed to the patient's forearm with the elastic bandage and radiation treatment begins. When the radiation dose required for treatment is reached, the control unit 1 emits a notification sound, the elastic bandage can be loosened, and the treatment device main body can be stored in the sealed storage area 15 using the clamp 12 and the robotic arm 13.

[0038] The present invention has been described by applying specific examples to explain the principles and embodiments of the present invention, but the description of the above examples is only used to understand the method of the present invention and its core concept, and at the same time, those skilled in the art may make changes to the specific embodiments and application scope based on the idea of ​​the present invention. Therefore, the contents of this specification should not be interpreted as limiting the present invention. [Explanation of symbols]
