Description

Technical Field

[0001] This invention relates to the field of CT scanning technology, and in particular to a standing CT scanning auxiliary device for radiology. Background Technology

[0002] When the human body is standing, organs and bones are affected by gravity. For example, in patients with lumbar disc herniation, the lesion may be hidden when lying down, but when standing, the pressure on the lesion is obvious. Therefore, standing CT scanning equipment is widely used in the fields of orthopedics and spinal surgery.

[0003] Generally, the patient's posture during a standing CT scan includes: standard standing, single-leg weight-bearing standing, and functional posture. The single-leg weight-bearing standing posture requires the patient to shift their weight onto one leg, with the other leg slightly off the ground or lightly touching the ground. This assesses the condition of a specific lower limb under primary weight-bearing or simulates the single-leg support phase of gait. The functional posture mainly includes spinal extension (head tilted back and back straight) and spinal flexion (bending over), assessing spinal stability during activity and used to detect spinal stenosis or vertebral displacement that only occurs in specific postures. Both of these postures require a high degree of coordination from the patient, especially for patients with underlying medical conditions. Positioning them is challenging and often requires assistance from others or a support system. Furthermore, during the CT scan after positioning, the patient is prone to swaying, and even slight swaying can lead to blurred images.

[0004] To address the aforementioned issues, current methods involve installing auxiliary supports next to CT scanners to help patients position themselves. However, most of these support structures are overly complex, occupy a large area, and have high production costs. Furthermore, the supports are not only difficult to adjust during use, but their bulky structure can also interfere with X-rays during scanning, affecting the imaging quality of the CT scanner. Therefore, this invention provides a standing CT scanner auxiliary device for radiology to meet these needs. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide a standing CT scan auxiliary device for radiology. By setting a second adjustment mechanism, the patient's arms can be supported and limited by the handles during use. Based on the support effect of the handles on the patient's arms, the device helps stabilize the patient's body, reducing the pressure on different parts of the body during positioning and improving the stability of the patient's body after positioning. This avoids the phenomenon of the patient's body swaying during CT scans. The auxiliary device provided by this application can meet the needs of standard standing position, single-leg weight-bearing standing position, and functional position, improving the practicality of the device. Through the above settings, the problems of difficulty in positioning and poor stability after positioning during standing CT scans can be solved.

[0012] Optionally, a third insert rod is symmetrically slidably connected to the inner wall of the handle, and the same third spring is fixedly connected to one end of the two third insert rods that are close to each other.

[0013] Optionally, a handle is fixedly connected to the bottom of the third insertion rod, the end of the handle has an outwardly curved arc shape, and an avoidance groove is provided at the bottom of the handle.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting a second adjustment mechanism, the auxiliary device can be adaptively adjusted according to the patient's body position during use, ensuring that the patient's arms can be supported and limited by the handle.

In addition, the adjustment structure of the first adjustment mechanism and the second adjustment mechanism is simple and the adjustment operation is convenient. Accidental touches will not easily occur during use, ensuring the convenience and safety of the device. Attached Figure Description

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0022] The present invention provides a standing CT scan auxiliary device for radiology, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0023] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0024] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0025] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0026] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0027] like Figures 1 to 6 As shown, an embodiment of the present invention provides a standing CT scanning auxiliary device for radiology, including a base plate 1, a base 2 fixedly connected to one side of the base plate 1, support rods 3 symmetrically installed on the top of the base 2, a plurality of limiting plates 4 fixedly connected to the outer wall of the support rods 3, reinforcing ribs 5 fixedly connected to the outer wall of the support rods 3, a top seat 6 fixedly connected to the top of the support rods 3, a horizontal arm 17 rotatably connected to the bottom of the top seat 6, vertical arms 20 rotatably connected to both ends of the horizontal arm 17, and a handle 28 slidably connected to the inner wall of the vertical arm 20.

[0028] In the above structure, the base 2 is fixed to one side of the base plate 1 with screws. The arc-shaped contour of the base 2 is consistent with the contour of the side of the base plate 1, ensuring the overall stability of the base plate 1 and the base 2 after they are fixed. Furthermore, several limiting plates 4 are provided on the outer wall of the support rod 3. The limiting plates 4 at the bottom and top of the support rod 3 are used to fix the relative positions between the support rod 3 and the base 2, and between the support rod 3 and the top seat 6, respectively. Four limiting plates 4 are provided at the middle position of the support rod 3. These four limiting plates 4 are divided into two groups of two. Each group of limiting plates 4 is fixed to the top and bottom of the reinforcing rib 5, respectively. This arrangement allows two reinforcing ribs 5 to be fixed at the middle position of the support rod 3. The reinforcing ribs 5 are used to improve the strength and stability of the overall structure of the support rod 3, so that the top seat 6 can bear a greater weight. Meanwhile, it avoids the problem of excessively long support rods 3 causing bending during use. Furthermore, the top seat 6 has a "T"-shaped profile. This profile not only allows both support rods 3 to be fixed to the bottom of the top seat 6 simultaneously, but also allows the cross arm 17 to be installed on a relatively long plate of the top seat 6, providing sufficient space between the cross arm 17 and the support rods 3 to accommodate the patient standing at the bottom of the cross arm 17. In summary, the base plate 1, base 2, support rods 3, reinforcing ribs 5, and top seat 6 constitute the support system of this auxiliary device. The support system has a reasonable structure, high structural strength, and a large capacity to accommodate different patient positions. In addition, the structure is simple, easy to assemble, and will not cause any scanning interference to the CT scanning equipment during use.

[0029] As one implementation method in this embodiment, such as Figures 6 to 12As shown, the first adjustment mechanism is used to adjust the relative position between the top seat 6 and the cross arm 17. The first adjustment mechanism is connected to the top seat 6 and the cross arm 17 respectively. The first adjustment mechanism includes a first adjustment plate 7 fixedly connected to the bottom of the top seat 6 and a first turntable 11 fixedly connected to the top of the cross arm 17. A first connecting rod 8 is fixedly connected to the top of the first adjustment plate 7. A first rotating shaft 12 and a second connecting rod 13 are fixedly connected to the top and bottom of the first turntable 11 respectively. A first positioning seat 14 is fixedly connected to the bottom outer wall of the first turntable 11. The first rotating shaft 12 is rotatably connected to... Inside the first connecting rod 8, a ball bearing 10 is rotatably connected to the top of the first connecting rod 8. The ball bearing 10 is located between the first connecting rod 8 and the first rotating shaft 12. The first adjusting plate 7 has several first adjusting holes 9 arranged in a circumferential array. The first positioning seat 14 is slidably connected to the first insert rod 15. The first insert rod 15 is inserted through and into both the first rotating plate 11 and the first adjusting holes 9. The inner wall of the first positioning seat 14 is fixedly connected to the first spring 16. One end of the first spring 16 is fixed to the inner wall of the first positioning seat 14, and the other end is fixed to the first insert rod 15.

[0030] The above structure specifically describes how the relative position between the top seat 6 and the cross arm 17 is adjusted by means of the first adjustment mechanism. Specifically, the top seat 6 and the cross arm 17 are mainly connected together by the first adjustment plate 7 and the first turntable 11. The first adjustment plate 7 and the first turntable 11 are rotatably connected together by the first connecting rod 8 and the first rotating shaft 12. In order to ensure the stability and smoothness of the rotation process, a ball bearing 10 is provided at the top of the first connecting rod 8. During the mutual rotation of the first connecting rod 8 and the first rotating shaft 12, the ball bearing 10 limits the movement while changing the sliding friction between the first connecting rod 8 and the first rotating shaft 12 into the rolling friction between the ball bearing 10 and the first connecting rod 8 and the first rotating shaft 12. This improves the smoothness of the rotation between the first connecting rod 8 and the first rotating shaft 12 and reduces wear and abnormal noise generated during the friction process.

[0031] Furthermore, since the first insert rod 15 is inserted through the first turntable 11 and the first adjustment hole 9, and the first adjustment plate 7 has several first adjustment holes 9 arranged in a circular array, the first adjustment plate 7 and the first turntable 11 can be connected and fixed by the first insert rod 15 and the first adjustment holes 9. At the same time, the user can change the position of the first insert rod 15 in the first adjustment holes 9 to adjust the relative angle between the first adjustment plate 7 and the first turntable 11. This adjustment method is not only simple in structure but also convenient to operate. After the first adjustment plate 7 and the first turntable 11 are fixed, the structure has high strength and there will be no slippage or misalignment. In addition, since a first spring 16 is provided inside the first positioning seat 14, the first insertion rod 15 is always inserted into the first adjustment hole 9 under the elastic force of the first spring 16. When the user needs to change the insertion position of the first insertion rod 15, he only needs to pull the first insertion rod 15 down to disengage it from the first adjustment hole 9 and then rotate the first turntable 11 to change the usage angle. When the user stops pulling the first insertion rod 15 down, the first insertion rod 15 automatically resets and re-inserts into the first adjustment hole 9 under the elastic force of the first spring 16. This structural design further improves the efficiency and convenience of adjusting the relative position between the first adjustment plate 7 and the first turntable 11.

[0032] As one implementation method in this embodiment, such as Figure 13 and Figure 14 As shown, the second adjustment mechanism is used to adjust the relative position between the horizontal arm 17 and the vertical arm 20. The second adjustment mechanism is connected to the horizontal arm 17 and the vertical arm 20 respectively. The second adjustment mechanism includes a second adjustment disk 18 fixedly connected to both ends of the horizontal arm 17 and a second turntable 21 fixedly connected to the top of the vertical arm 20. The second adjustment disk 18 and the second turntable 21 are rotatably connected together by a second rotating shaft 25. A second positioning seat 19 is fixedly connected to the outer wall of the second adjustment disk 18. A plurality of second adjustment holes 22 distributed in a circular array are opened on the second turntable 21. A second insertion rod 23 is slidably connected inside the second positioning seat 19. The second insertion rod 23 is inserted through the second adjustment disk 18 and the second adjustment hole 22. A second spring 24 is fixedly connected to the inner wall of the second positioning seat 19. One end of the second spring 24 is fixedly connected to the inner wall of the second positioning seat 19, and the other end is fixed to the second insertion rod 23.

[0033] The above structure describes how the relative position between the horizontal arm 17 and the vertical arm 20 is adjusted using the second adjustment mechanism. Specifically, the two vertical arms 20 are rotatably connected to the second adjustment discs 18 at both ends of the horizontal arm 17 via the second turntable 21 and the second rotating shaft 25, respectively. The second turntable 21 has several second adjustment holes 22 arranged in a circular array. Since the second insertion rod 23 is simultaneously inserted into the second adjustment disc 18 and the second adjustment hole 22, the second turntable 21 and the second adjustment disc 18 can be fixed together using the second insertion rod 23. Simultaneously, the user can adjust the position of the second insertion rod 23. The vertical arm 20 is inserted into different second adjustment holes 22 to adjust the relative angle between the vertical arm 20 and the second adjustment disk 18. It is worth mentioning that the adjustment method between the second adjustment disk 18 and the second turntable 21 is the same as the adjustment method between the first adjustment disk 7 and the first turntable 11. Therefore, the operation used by the user when adjusting this device is the same. This design can further improve the efficiency of the user in adjusting this device. Similarly, the adjustment principle between the second adjustment disk 18 and the second turntable 21 can be referred to the adjustment principle between the first adjustment disk 7 and the first turntable 11, which will not be elaborated here.

[0034] In this embodiment, as Figures 13 to 17 As shown, a limiting groove 26 is provided on the inner wall of the vertical arm 20, and the handle 28 is slidably connected in the limiting groove 26. A third insert rod 29 is symmetrically slidably connected on the inner wall of the handle 28. The two third insert rods 29 are fixedly connected to the same third spring 31 at their close ends. Several third adjustment holes 27 are provided through the vertical arm 20 in a linear arrangement. The third insert rods 29 are inserted into the third adjustment holes 27. A handle 30 is fixedly connected to the bottom of the third insert rod 29. The end of the handle 30 has an outwardly curved arc shape. An avoidance groove 32 is provided at the bottom of the handle 28.

[0035] The above structure mainly describes the relative sliding adjustment method between the handle 28 and the vertical arm 20. Specifically, the third rods 29 at both ends of the handle 28 are simultaneously inserted into the third adjustment holes 27 on the vertical arm 20. The relative position between the handle 28 and the vertical arm 20 is fixed by means of the third rods 29 and the third adjustment holes 27. Since several linearly arranged third adjustment holes 27 are provided on the vertical arm 20, the user can change the position of the third rods 29 within the third adjustment holes 27 to adjust the relative position between the handle 28 and the vertical arm 20. Furthermore, since the same third spring 31 is installed at the ends of the two third rods 29 that are close to each other, the spring force of the third spring 31 ensures that the third rods 29 are always inserted into the third adjustment holes 27. Inside the hole 27, the user can pry the handles 30 at the bottom of the two third rods 29 inward to bring them closer together and disengage them from the third adjustment hole 27, thereby releasing the fixing effect between the handle 28 and the vertical arm 20. Once the fixing effect is released, the user can slide the handle 28 to change the relative position between the vertical arm 20 and the handle 28. When the user stops prying the handles 30 inward, the third rods 29 automatically reset under the elastic force of the third spring 31 and re-insert into the third adjustment hole 27 to continue fixing the handle 28 and the vertical arm 20. The above adjustment method is not only simple in structure but also convenient to operate, and will not easily cause accidental touches. Moreover, the structure for adjusting the relative position between the handle 28 and the vertical arm 20 is installed on the handle 28 itself, which makes it convenient for the user to operate.

[0036] In summary, the auxiliary device provided in this application mainly consists of a support system and two parts: a horizontal arm 17 and a vertical arm 20 mounted on the support system. During a CT scan, the patient can use the handle 28 to provide stable support for their upper limbs. The patient can then use the support of their upper limbs to correct their posture. Specifically, during a CT scan, the patient stands on top of the base plate 1, holds the handle 28 with both hands, and adjusts the height of the handle 28 on the vertical arm 20 according to the required posture so that the height of the hands is suitable for the required posture. The relative angle between the vertical arm 20 and the horizontal arm 17 can be adjusted so that the patient's upper limbs can be extended or retracted to a suitable angle, making it convenient for the patient to use their hands to stabilize their body. This structural design not only meets the requirements of different postures but is also convenient and efficient to operate during adjustment.

[0037] Optionally, by setting a first adjustment mechanism, the relative angle between the cross arm 17 and the top seat 6 can be adjusted, thereby allowing the overall direction of use of the auxiliary device to be adjusted. This setting is to ensure that the auxiliary device will not block the X-rays of the CT scanning equipment during use, making it suitable for patients to be placed in different positions and improving the practicality of the device.

[0038] The working principle of the technical solution provided by this invention is as follows: When it is necessary to adjust the angle between the top seat 6 and the cross arm 17, the user pulls down the first insert rod 15 so that the end of the first insert rod 15 is disengaged from the first adjustment hole 9, and then rotates the cross arm 17 to change the angle. When the angle is determined, the user stops pulling the first insert rod 15. Under the elastic force of the first spring 16, the first insert rod 15 automatically resets and re-inserts into the first adjustment hole 9 to achieve the effect of fixing the cross arm 17.

[0039] When it is necessary to adjust the relative position between the horizontal arm 17 and the vertical arm 20, the user pulls the second insert rod 23 outward so that the end of the second insert rod 23 disengages from the second adjustment hole 22, and then rotates the vertical arm 20 to change the angle. When the angle is determined, the user stops pulling the second insert rod 23. Under the elastic force of the second spring 24, the second insert rod 23 automatically resets and re-inserts into the second adjustment hole 22 to achieve the effect of fixing the vertical arm 20.

[0040] When it is necessary to adjust the relative position between the handle 28 and the vertical arm 20, the user first pries the handles 30 at the bottom of the two third rods 29 inward so that the two third rods 29 move closer to each other and disengage from the third adjustment hole 27, thereby releasing the fixing effect between the handle 28 and the vertical arm 20. After the fixing effect is released, the user can slide the handle 28 to change the relative position between the vertical arm 20 and the handle 28. When the user stops prying the handles 30 inward, the third rods 29 automatically reset under the elastic force of the third spring 31 and re-insert into the third adjustment hole 27 to continue fixing the handle 28 and the vertical arm 20.

[0041] When the patient assumes a standard standing position (e.g.) Figure 1 (As shown): The patient stands with both feet on top of the base plate 1, with their head aligned with the center of the first adjustment disc 7. At this time, the patient's arms hang naturally. The user first adjusts the relative angle between the vertical arm 20 and the horizontal arm 17 so that the vertical arm 20 is perpendicular to the horizontal arm 17. After adjustment, the vertical arm 20 is parallel to the patient's upper arm. Then, the user adjusts the height of the handle 28 on the vertical arm 20 so that the patient's hands can just hold the handle 28. At this time, with the support of the handle 28 for the patient's arms, the patient's body can be stabilized, allowing the patient to stand steadily on the base plate 1, ensuring that the patient will not shake during the CT scan.

[0042] When the patient is in a single-leg weight-bearing standing position (such as...) Figure 18(As shown): The patient stands with both feet on top of the base plate 1, with their head aligned with the center of the first adjustment disc 7. At this time, the patient's arms hang naturally. The user first adjusts the relative angle between the vertical arm 20 and the horizontal arm 17 according to the position of the patient's weight-bearing leg, so that both vertical arms 20 are tilted towards the direction of the weight-bearing leg. After the angles of both vertical arms 20 are adjusted, the height of the handle 28 on the vertical arm 20 is adjusted so that the patient's hands can just hold the handle 28. At this time, the patient slightly raises the leg that does not need to bear weight, and the whole body tilts towards the direction of the leg that needs to bear weight. Then, the patient holds the handle 28 with both hands, using the support of the handle 28 on the upper arms to stabilize the body. Since the tilt direction of the two vertical arms 20 is the same as the tilt direction of the patient's body, the patient's body can remain stable during the CT scan with the help of the support of the handle 28 on both arms, and the body will not sway due to weight-bearing on one side.

[0043] When the patient is in a functional position with spinal extension (e.g.) Figure 19 As shown), the patient stands with both feet on top of the base plate 1, with their head positioned in front of the center of the first adjustment disc 7. At this time, the patient's arms hang naturally in front of the vertical arm 20. Then, the patient tilts their head back and straightens their back according to the required posture, while extending their arms outward and tilting them backward (extending their arms and tilting them backward helps the patient open their chest cavity, making it easier for them to exert force to straighten their back). After the patient's posture is adjusted, the user first adjusts the relative angle between the vertical arm 20 and the horizontal arm 17 so that the angle of the two vertical arms 20 is consistent with the angle of the patient's arms when they are extended outward. Then, the user adjusts the height of the handle 28 on the vertical arm 20 according to the position of the patient's hands so that the patient's hands can just hold the handle 28. At this time, the patient's body can be supported by the handle 28, which not only prevents the patient from leaning backward excessively during the spinal extension process, but also prevents the patient from experiencing fatigue due to maintaining the posture for a long time, and prevents the patient's body from swaying during the CT scan.

[0044] When the patient performs a functional position of forward flexion (e.g.) Figure 20As shown), the patient stands with both feet on top of the base plate 1, with their head positioned behind the center of the first adjustment disc 7. At this point, the patient's arms hang naturally behind the vertical arm 20. The patient then bends over according to their desired posture, with their arms hanging naturally and moving towards each other in front of their body (this helps open the spine during bending). After the patient's posture is adjusted, the user first adjusts the relative angle between the vertical arm 20 and the horizontal arm 17 so that the angle between the two vertical arms 20 and the angle of the patient's arms when they are close together is consistent. Then, the user adjusts the height of the handle 28 on the vertical arm 20 according to the position of the patient's hands, so that the patient's hands can comfortably grip the handle 28. With the support of the handle 28 on the patient's arms, the pressure on the patient's upper body is concentrated on the handle 28, thus reducing the pressure on the spine during bending over and preventing the patient from leaning forward or backward, thereby improving the stability of the patient's body during the CT scan.
