Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of radiotherapy equipment, and more specifically, to an arm positioning support device and a radiotherapy positioning device. Background Technology
[0002] At present, radiotherapy has become an important technical means for cancer treatment in major hospitals. Tumor radiotherapy mainly uses high-energy rays to precisely destroy tumor cells, causing cancer cells to die. Some patients need to undergo radiotherapy in the chest and abdomen areas. The treatment time is mostly between 10 and 30 minutes. During this period, the arms need to be kept raised and the treatment area needs to remain still.
[0003] In existing technologies, to ensure patient comfort during treatment and to facilitate initial positioning of the patient's head, neck, and shoulders, the head, neck, and shoulder area of the bed board is typically designed with an arc-shaped structure that conforms to the natural curve of the human head, neck, and shoulders. If an arm positioning support device is included, it needs to be detachably connected to the bed board. When treating the head and neck, the arm positioning support device needs to be disassembled; when treating areas requiring the patient's arms to be raised, it needs to be installed on the bed board. Currently, the mounting surface of existing arm positioning supports is generally flat, which results in poor ease of installation and connection stability between flat and arc-shaped surfaces. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing arm positioning support devices, which are difficult to connect conveniently and stably to the bed board, and to provide an arm positioning support device and a radiotherapy positioning device, wherein the arm positioning support device can be conveniently and stably connected to the bed board.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] An arm positioning support device is provided, including an arm positioning support plate. The arm positioning support plate includes an arc-shaped mounting part that mates with an arc-shaped mounting surface, a support part for supporting the arm, and a connecting part disposed between the arc-shaped mounting part and the support part. The support part is located on both sides of the arc-shaped mounting part and is higher than the arc-shaped mounting part.
[0007] In this utility model, the arm positioning and support device is used by placing the arc-shaped mounting part of the arm positioning and support plate on the arc-shaped mounting surface of the bed board, and then fixing the arm positioning and support plate to the bed board using a fixing component. The arc-shaped mounting part allows for convenient and stable connection between the arm positioning and support device and the support part, providing support for the arm and improving the patient's comfort in maintaining a fixed position during treatment.
[0008] Furthermore, the support portion is provided with a support groove. By providing the support groove, it is convenient to provide support for the arm.
[0009] Furthermore, it also includes a first connecting assembly for connecting to the curved mounting surface, the first connecting assembly being disposed on the support portion. Providing a connecting assembly facilitates the mounting of the arm positioning support plate onto the bed board.
[0010] Furthermore, the first connecting assembly includes a fixing member and a locking block. The fixing member is mounted on the arm positioning support plate, and the locking block is rotatably connected to the fixing member. A clamping space exists between the locking block and the arm positioning support plate. When installing the arm positioning support plate, simply rotating the locking block to position the bed board within the clamping space completes the installation of the arm positioning support plate, which is convenient and quick.
[0011] Furthermore, the first connecting assembly is provided in two sets, with the two sets of the first connecting assembly located on both sides of the arc-shaped mounting portion. When fixing the arm positioning support plate, only two locking blocks need to be rotated, and the two sets of first connecting assemblies and the arc-shaped mounting portion form a triangular support, which facilitates the stable fixing of the arm positioning support plate.
[0012] Furthermore, it also includes a handle and a second connecting component, the handle being slidably mounted on the bottom surface of the support portion via the second connecting component. By providing the handle, the patient can grip it with both hands after supporting their arms on the arm positioning support plate. The second connecting component allows the handle to be adjusted to a suitable position for the patient to grip according to different arm shapes, making the arm placement more comfortable and providing appropriate fixation force and position. This improves the patient's comfort in maintaining a fixed position during treatment, reduces the possibility of abnormal movement, ensures the accuracy of treatment, and further guarantees the smooth progress of treatment.
[0013] Furthermore, the second connecting assembly includes a fixing component and a sliding seat. The sliding seat is slidably mounted on the bottom surface of the support via the fixing component, and the sliding seat can be fixed by the fixing component. The handle is mounted and connected to the sliding seat. When adjusting the position of the handle, the sliding seat is slid in the fixing component, and after the handle is adjusted to a suitable position for the patient, the position of the sliding seat is fixed using the fixing component.
[0014] Furthermore, the fixing component includes a fixing block and a first positioning member. The fixing block is disposed on the arm positioning support plate, and the first positioning member is connected to the fixing block. The sliding seat is provided with a plurality of second positioning members for connecting with the first positioning member. After the sliding seat is moved to the desired position, the first positioning member and the second positioning member cooperate to fix the sliding seat in the desired position.
[0015] Furthermore, the grip is designed as an M-shaped grip, comprising a connecting part, a holding part, and a fixing part. The holding part is located at both ends of the connecting part and between the connecting part and the fixing part, with an acute angle between the holding part and the fixing part. By designing the grip as an M-shape and making the angle between the holding part and the fixing part acute, the patient's hands naturally curl inward when holding the grip, improving the patient's grip comfort.
[0016] This utility model also provides a radiotherapy positioning device, including a bed board and the arm positioning support device described above, wherein the arc-shaped mounting part is mounted and connected to the bed board.
[0017] The radiotherapy positioning device of this utility model allows the patient to raise both arms. When the patient needs to raise both arms, the arc-shaped mounting part of the arm positioning support plate is placed on the arc-shaped mounting surface of the bed board, and the arm positioning support plate is fixed to the bed board. This allows the arm positioning support device to be easily and stably connected to the bed board. After the patient lies face up on the bed board, the arm positioning support plate can support and fix both arms, providing appropriate fixation force and position for the arms.

[0031] Example 1
[0032] This embodiment is the first embodiment of the arm positioning and support device, such as Figure 1 and Figure 2 As shown, the device includes an arm positioning support plate 100. The arm positioning support plate 100 includes an arc-shaped mounting portion 110 that mates with an arc-shaped mounting surface, a support portion 120 for supporting the arm, and a connecting portion 130 located between the arc-shaped mounting portion 110 and the support portion 120. The support portion 120 is located on both sides of the arc-shaped mounting portion 110 and is higher than the arc-shaped mounting portion 110, meaning the arc-shaped mounting portion 110 is recessed towards the bed board 500. By providing the arc-shaped mounting portion 110, the patient's head is limited, thereby further improving the accuracy of repeated positioning. Simultaneously, by providing the arc-shaped mounting portion 110, it is easy to connect the arm positioning support plate 100 to other mounted objects. In this embodiment, the arc-shaped mounting portion 110 is a curved surface conforming to the human head, neck, and shoulders. The outer periphery of the arm positioning support plate 100 is also provided with a flange, and the curved surface of the arm positioning support plate 100 is provided with reinforcing ribs, increasing the rigidity of the proton arm positioning support plate 100 when fixing the patient. The end of the arm positioning support plate 100 near the bed board is designed as an arc shape that is recessed towards the curved mounting part 110. The arm positioning support plate 100 is installed and connected above the bed board. When the patient lies on the bed board, the patient's neck is located at the connection between the arm positioning support plate 100 and the bed board. By designing the connection as an arc shape that is recessed towards the curved mounting part 110, it is easier to avoid gaps between the patient and the connection, thus improving the patient's comfort when lying flat.
[0033] The support part 120 is provided with a support groove. The support groove facilitates the provision of support for the arm.
[0034] like Figure 2 As shown, it also includes a first connecting component 200 for connecting to the curved mounting surface, the first connecting component 200 being disposed on the support portion 120. The first connecting component 200 facilitates the mounting of the arm positioning support plate 100 onto the bed board.
[0035] like Figure 3 As shown, the first connecting assembly 200 includes a fixing member 210 and a locking block 220. The fixing member 210 is mounted on the arm positioning support plate 100, and the locking block 220 is rotatably connected to the fixing member 210. There is a clamping space between the locking block 220 and the arm positioning support plate 100. When installing the arm positioning support plate 100, it is only necessary to rotate the locking block 220 to place the bed board within the clamping space, which completes the installation of the arm positioning support plate 100, which is convenient and quick. In this embodiment, the locking block 220 is set as an L-shaped locking block that fits the bottom curved surface of the bed board 500. When the L-shaped locking block abuts against the bottom of the bed board 500, the L-shaped locking block fits the bottom curved surface of the bed board 500.
[0036] like Figure 2 As shown, there are two sets of first connecting components 200, located on opposite sides of the arc-shaped mounting portion 110. When fixing the arm positioning support plate 100, only two locking blocks 220 need to be rotated, forming a triangular support with the arc-shaped mounting portion 110, facilitating stable fixing of the arm positioning support plate 100. In this embodiment, the two sets of first connecting components 200 are located at the end of the arm positioning support plate 100 closest to the bed board.
[0037] The working principle of the arm positioning and support device in this embodiment is as follows:
[0038] In use, the curved mounting part 110 of the arm positioning support plate 100 is placed on the curved mounting surface of the bed board, and then the arm positioning support plate 100 is fixed to the bed board by the fixing components. By setting the curved mounting part 110, the arm positioning support device can be easily and stably connected to the bed board; by setting the support part 120, support is provided for the arm, improving the patient's comfort in maintaining a fixed position during treatment.
[0039] Example 2
[0040] This embodiment is a second embodiment of an arm positioning support device. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 2 and Figure 4As shown, it also includes a handle 300 and a second connecting assembly 400. The handle 300 is slidably mounted on the bottom surface of the support portion 120 via the second connecting assembly 400. Two sets of the second connecting assembly 400 are provided. When there is only one handle 300, the two sets of second connecting assemblies 400 are respectively connected to both ends of the handle 300; when there are two handles 300, the two sets of second connecting assemblies 400 are respectively connected to the two handles 300. In this embodiment, only one handle 300 is provided. The end of the handle 300 is provided with a mounting hole. The sliding seat 420 is provided with a mounting block, which is inserted into the mounting hole. The mounting block and the mounting hole are then fixedly connected by a fixing pin. By setting the handles 300, the patient can grasp the handles 300 with both hands after supporting their arms on the arm positioning support plate 100. By setting the second connecting component 400, the handles 300 can be adjusted to a suitable position for the patient to grasp according to different arm shapes, making the arm position more comfortable and providing appropriate fixation force and position for the arm. This improves the patient's comfort in maintaining a fixed position during treatment, reduces the possibility of abnormal movement, ensures the accuracy of treatment, and further ensures the smooth progress of treatment.
[0041] like Figure 5 As shown, the second connecting assembly 400 includes a fixing assembly 410 and a sliding seat 420. The sliding seat 420 is slidably mounted on the bottom surface of the support portion 120 via the fixing assembly 410. The sliding seat 420 can be fixed by the fixing assembly 410, and the handle 300 is mounted and connected to the sliding seat 420. When adjusting the position of the handle 300, the sliding seat 420 is slid in the fixing assembly 410, and after the handle 300 is adjusted to a suitable position for the patient, the position of the sliding seat 420 is fixed using the fixing assembly 410.
[0042] like Figure 5 As shown, the fixing component 410 includes a fixing block 411 and a first positioning member 412. The fixing block 411 is disposed on the arm positioning support plate 100, and the first positioning member 412 is connected to the fixing block 411. The sliding seat 420 is provided with a plurality of second positioning members 421 for connecting with the first positioning member 412. After the sliding seat 420 is moved to the desired position, the first positioning member 412 and the second positioning member 421 cooperate to position and fix the sliding seat 420 in the desired position.
[0043] Specifically, in this embodiment, the fixing block 411 includes a fixing seat 411a and a cam structure 411b. The fixing seat 411a is mounted on the arm positioning support plate 100. The cam structure 411b is rotatably connected to the fixing seat 411a. The first positioning member 412 is slidably connected to the fixing seat 411a and abuts against the cam structure 411b. The sliding seat 420 is slidably connected to the fixing seat 411a. After the sliding seat 420 is moved to the desired position, the cam structure 411b is rotated. The cam structure 411b drives the first positioning member 412 to slide in the fixing seat 411a. The first positioning member 412 moves toward the second positioning member 421, allowing the first positioning member 412 to connect with one of the second positioning members 421, thus fixing the sliding seat 420 in the desired position. This simplifies the process of fixing patients for medical workers and reduces the difficulty of treatment for medical workers.
[0044] The sliding seat 420 is provided with multiple scale markings 422, with each second positioning element 421 corresponding to one scale marking 422. This improves the ease, accuracy, and stability of the sliding seat 420's repeatability, thereby improving the accuracy of the grip 300's repeatability and ensuring that the patient remains in the same position during each treatment.
[0045] In this embodiment, the cam structure 411b is configured as a locking handle with a cam. The locking handle has two annular grooves at both ends of the cam. After the locking handle is inserted into the fixed seat 411a, the two limiting buckles are respectively inserted into the two annular grooves, and the locking handle and the fixed seat 411a are rotatably connected. When the far end of the locking handle abuts against the first positioning member 412, the first positioning member 412 is connected to the second positioning member 421. The locking handle is also provided with a small-angle boss to limit the rotation range of the handle to 90 degrees. The first positioning element 412 is a positioning plate with spherical protrusions, and the second positioning element 421 is a spherical recess. The contact surface between the sliding seat 420 and the first positioning element 412 is provided with a plurality of evenly arranged spherical recesses. When the sliding seat 420 is locked, the spherical protrusions on the positioning plate will automatically slide and align into the spherical recesses, thereby improving the ease, accuracy and stability of repeated positioning of the sliding seat 420. Different locking positions can be adjusted for patients with different arm shapes to make the arm more comfortable.
[0046] like Figure 6As shown, the handle 300 is designed as an M-shaped handle, comprising a connecting portion 310, a gripping portion 320, and a fixing portion 330. The gripping portions 320 are located at both ends of the connecting portion 310 and between the connecting portion 310 and the fixing portion 330, with an acute angle between the gripping portion 320 and the fixing portion 330. By designing the handle 300 as an M-shape and making the angle between the gripping portion 320 and the fixing portion 330 acute, the patient's hands naturally clench inward when holding the handle 300, improving the patient's grip comfort. In this embodiment, the cross-sectional area of the gripping portion 320 gradually decreases from the middle to both ends, improving grip comfort and providing a clearer grip position.

Figure 2 As shown, the device includes a bed board 500 and an arm positioning support device, with an arc-shaped mounting part 110 mounted on the bed board 500. In this embodiment, the bed board 500 has a curved surface that conforms to the human shoulder, neck, and head, and a flat plate that supports the body. The curved surface is connected to the flat plate. The arm positioning support plate 100 is placed on the curved surface of the bed board 500, and the curved surface of the arc-shaped mounting part 110 is in contact with the curved surface of the bed board 500.
[0049] The working principle of a radiotherapy positioning device in this embodiment is as follows:
[0050] When it is necessary to raise the patient's arms, place the arc-shaped mounting part 110 of the arm positioning support plate 100 on the arc-shaped mounting surface of the bed board, fix the arm positioning support plate 100 to the bed board 500, so that the arm positioning support device can be easily and stably connected to the bed board. After the patient lies face up on the bed board 500, the arm positioning support plate 100 can support and fix the arms, so as to provide appropriate fixation force and position for the arms.
