Description

Technical Field

[0001] This invention relates to the field of imaging equipment technology, specifically to an optical imaging swing arm structure. Background Technology

[0002] Medical imaging refers to the techniques and processes used to obtain images of internal tissues of the human body or a part of the human body in a non-invasive manner for medical treatment or medical research. It includes two relatively independent research directions: medical imaging system and medical image processing. As a science, medical imaging belongs to biological imaging and includes imaging diagnostics, radiology, endoscopy, medical thermal imaging technology, medical photography and microscopy. In addition, it includes techniques such as brain wave imaging and magnetoencephalography.

[0003] When imaging internal organs, patients often need to lie on a special imaging bed. However, this imaging method only obtains a frontal image of the internal organs and cannot capture images from the patient's back or sides, resulting in incomplete image data in some cases. Therefore, this application proposes an optical imaging swing arm structure that can capture images of the patient's internal organs from all angles. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an optical imaging swing arm structure that offers advantages such as omnidirectional imaging. This solves the problem that traditional methods cannot capture images from the patient's back and sides when the patient is lying flat, resulting in incomplete image data in some cases.

[0005] To achieve the aforementioned omnidirectional shooting objective, this invention provides the following technical solution: an optical image swing arm structure, comprising a base plate, a standing plate fixedly mounted on the top of the base plate, columns fixedly mounted on the top of the base plate and around the perimeter of the standing plate, a top ring track fixedly mounted on the top of each column, top ring teeth fixedly mounted on the outer side of the top ring track, a driving device slidably mounted on the surface of the top ring track, a hanging plate fixedly mounted on the bottom of the driving device, an imager fixedly mounted on the bottom of the hanging plate, and a radiation protection device slidably mounted on the standing plate and fixedly connected to the hanging plate. The driving device includes a sleeve frame movably mounted on the surface of the top ring track. A motor is fixedly mounted on the top of the sleeve frame. A drive shaft extending into the inside of the sleeve frame is fixedly mounted on the output end of the motor. A drive toothed roller that meshes with the teeth of the top ring is fixedly mounted on the surface of the drive shaft. A driven roller is rotatably mounted on the inner wall of the sleeve frame and located inside the top ring track. An inner roller that contacts the inner wall of the sleeve frame is fixedly mounted on the surface of the driven roller. The radiation protection device includes an outer plate slidably mounted on a standing plate. An inner plate is fixedly mounted on the inner side of the outer plate. An imaging port penetrating the inner plate is opened on the outer plate.

[0006] Furthermore, both the substrate and the standing plate are circular plates, the centers of the substrate and the standing plate coincide, a circular ring groove is formed at the top of the standing plate, and the cross section of the ring groove is in a "convex" shape.

[0007] Furthermore, a limiting sliding plate extending into the interior of the ring groove is fixedly installed at the bottom of the outer plate. Both the outer plate and the limiting sliding plate are arc-shaped, the central angles of both the outer plate and the limiting sliding plate are 100 - 110 degrees, and the centers of the outer plate, the inner plate and the limiting sliding plate coincide with the center of the standing plate.

[0008] Furthermore, the outer plate is an iron plate, the inner plate is a lead plate, nylon cloth sleeves are wrapped on the surfaces of both the outer plate and the inner plate, and a connecting arm fixedly connected to the hanging plate is fixedly installed on the front surface of the outer plate.

[0009] Furthermore, the photographing port is aligned with the photographing device. The photographing port is rectangular, and the length of the photographing port is 2 - 3 centimeters smaller than the width of the outer plate.

[0010] Furthermore, both the top ring track and the top ring teeth are circular rings. The centers of the top ring track and the top ring teeth and the center of the standing plate are on the same vertical line, and the inner wall of the top ring track is a polished surface.

[0011] Furthermore, the side view shape of the sleeve frame is in a "C" shape. The inner top wall and the inner bottom wall of the sleeve frame are respectively in contact with the top wall and the bottom wall of the top ring track. The top view shape of the sleeve frame is arc-shaped. The central angle of the sleeve frame and the center of the top ring teeth are on the same vertical line. A shaft hole adapted to the driving shaft is formed at the top of the sleeve frame, and the motor is located outside the top ring track.

[0012] Furthermore, bearings are fixedly installed at the bottom end of the driving shaft and at both ends of the driven roller. The outer rings of the bearings are fixedly connected to the inner wall of the sleeve frame, and the driven roller is rotationally connected to the sleeve frame through the bearings.

[0013] 更多信息,请访问https: / / www.patentguru.com / Furthermore, a docking plate fixedly connected to the photographing device is fixedly installed at the bottom of the hanging plate, and a data transmitter is fixedly installed on the outer surface of the photographing device.

[0014] Furthermore, the photographing device includes a body. A lens is fixedly installed at the output end of the body. The lens is aligned with the same vertical line where the center of the top ring track and the center of the standing plate are located. A protective lens is fixedly installed on the surface of the body and on the surface of the lens.

[0015] Compared with the prior art, the present invention provides an optical imaging swing arm structure, which has the following beneficial effects:

[0016] 1. This optical imaging swing arm structure, through a drive device, drives the hanging plate and the camera at the lower end of the hanging plate to move in a circular motion around the top ring track, so as to take pictures of the patient standing on the standing plate from all directions. This shooting method can achieve 360-degree imaging of the patient's internal organs without blind spots, which greatly improves the comprehensiveness and accuracy of the patient's imaging data.

[0017] 2. This optical imaging swing arm structure, by rotating and installing an anti-radiation device on the standing plate, allows the patient to stand behind the anti-radiation device during imaging, leaving only the imaging port located in the direction of the patient's abdomen or chest. This allows the imaging device to only image the patient's internal organs, thereby significantly reducing the radiation impact on the patient's body. At the same time, because a connecting arm fixedly connected to the hanging plate is added to the outer side of the outer plate, the anti-radiation device will also rotate synchronously when the imaging device is moved by the hanging plate, thus ensuring that the anti-radiation device can always intercept excess radiation from the imaging device.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-5, An optical imaging swing arm structure, including a substrate 1, a standing plate 2 is fixedly installed on the top of the substrate 1, columns 3 are fixedly installed around the standing plate 2 on the top of the substrate 1, a top ring track 4 is fixedly installed on the top of the column 3, a top ring gear 5 is fixedly installed on the outside of the top ring track 4, a driving device 6 is slidably installed on the surface of the top ring track 4, a hanging plate 7 is fixedly installed at the bottom of the driving device 6, and a camera 8 is fixedly installed at the bottom of the hanging plate 7.

[0026] Please refer to Figure 5 , both the substrate 1 and the standing plate 2 are circular plates, and the centers of the substrate 1 and the standing plate 2 coincide. An annular groove 21 is opened on the top of the standing plate 2, and the cross-section of the annular groove 21 is "convex" shaped.

[0027] Among them, both the top ring track 4 and the top ring gear 5 are circular, and the centers of the top ring track 4 and the top ring gear 5 and the center of the standing plate 2 are on the same vertical line. The inner wall of the top ring track 4 is a polished surface to reduce the resistance with the driving device 6.

[0028] The driving device 6 is used to drive the hanging plate 7 and the camera 8 at the bottom of the hanging plate 7 to perform a circular motion around the patient, so as to achieve a 360-degree dead-angle-free shooting of the patient's internal organs, so as to obtain a comprehensive and reliable image of the patient's internal organs.

[0029] Please refer to Figure 2 , the driving device 6 includes a sleeve frame 61 movably installed on the surface of the top ring track 4, a motor 62 is fixedly installed on the top of the sleeve frame 61, a driving shaft 63 extending into the sleeve frame 61 is fixedly installed at the output end of the motor 62, a driving gear roller 64 meshing with the top ring gear 5 is fixedly installed on the surface of the driving shaft 63, and a driven roller 65 is rotatably installed on the inner wall of the sleeve frame 61 and inside the top ring track 4, and an inner roller 66 contacting the inner wall of the sleeve frame 61 is fixedly installed on the surface of the driven roller 65.

[0030] The sleeve frame 61 is stably installed on the top ring track 4 through the driving gear roller 64 and the inner roller 66. When the motor 62 rotates, the driving gear roller 64 can be driven to rotate, and the relationship between the driving gear roller 64 and the top ring gear 5 is used to drive the sleeve frame 61 to move on the top ring track 4.

[0031] Among them, the side view shape of the sleeve frame 61 is "匚" shaped, and the inner top wall and the inner bottom wall of the sleeve frame 61 are respectively in contact with the top wall and the bottom wall of the top ring track 4. The top view shape of the sleeve frame 61 is arc-shaped, and the central angle of the sleeve frame 61 and the center of the top ring gear 5 are on the same vertical line, so as to ensure that the sleeve frame 61 will make a circular motion with the center of the top ring gear 5 as the center point.

[0032] Secondly, a shaft hole adapted to the driving shaft 63 is opened on the top of the sleeve frame 61, and the motor 62 is located outside the top ring track 4.

[0033] In addition, bearings are fixedly installed at the bottom end of the drive shaft 63 and at both ends of the driven roller 65. The outer ring of the bearing is fixedly connected to the inner wall of the sleeve frame 61, and the driven roller 65 is rotatably connected to the sleeve frame 61 through the bearing.

[0034] A radiation shielding device 10 is slidably installed on the standing board 2 and fixedly connected to the hanging board 7 to block the radiation generated by the camera 8 from affecting other parts of the patient.

[0035] The radiation protection device 10 includes an outer plate 101 that is slidably mounted on a standing plate 2, an inner plate 102 that is fixedly mounted on the inner side of the outer plate 101, and a shooting port 103 that penetrates the inner plate 102 on the outer plate 101.

[0036] The outer plate 101 is made of iron, while the inner plate 102 is made of lead. The double interception of iron and lead plates is used to shield the X-rays from affecting other parts of the human body. Both the outer plate 101 and the inner plate 102 are covered with nylon cloth.

[0037] Secondly, a connecting arm 11, which is fixedly connected to the hanging plate 7, is fixedly installed on the front of the outer panel 101 and above the shooting port 103. There are three connecting arms 11, and the three connecting arms 11 form a tripod to improve the strength of the connection between the connecting arm 11 and the hanging plate 7.

[0038] When the frame 61 moves on the top ring track 4, the anti-radiation device 10 can be rotated synchronously through the hanging plate 7 and the connecting arm 11, so that no matter where the camera 8 moves, the anti-radiation device 10 can always intercept the radiation generated by the anti-radiation device 10 in a positive direction.

[0039] A limiting slide plate 104 extending into the annular groove 21 is fixedly installed at the bottom of the outer plate 101. Both the outer plate 101 and the limiting slide plate 104 are arc-shaped, and the central angle of both the outer plate 101 and the limiting slide plate 104 is 100-110 degrees. The centers of the outer plate 101, the inner plate 102, and the limiting slide plate 104 coincide with the center of the standing plate 2. This ensures that the radiation shielding device 10 can make standard circular movements.

[0040] In addition, the imaging port 103 is aligned with the imaging device 8, and the imaging port 103 is rectangular. The length of the imaging port 103 is 2-3 cm smaller than the width of the outer plate 101, ensuring that the imaging device 8 can completely image the patient's internal organs.

[0041] A docking plate 71, which is fixedly connected to the camera 8, is fixedly installed at the bottom of the hanging plate 7. A data transmitter 9 is fixedly installed on the outer surface of the camera 8. The images captured by the camera 8 are synchronized to the terminal equipment outside the camera room through the data transmitter 9.

[0042] Please see Figure 3The camera 8 includes a body 81, and a lens 82 is fixedly installed at the output end of the body 81. The lens 82 is aligned with the center of the top ring track 4 and the center of the standing plate 2 on the same vertical line. A protective lens 83 is fixedly installed on the surface of the body 81 and on the surface of the lens 82.

[0043] Working principle:

[0044] 1. First, the patient stands on the standing board 2 from the outside and remains standing.

[0045] 2. Then start motor 62 via terminal;

[0046] 3. When the motor 62 rotates, it drives the drive toothed roller 64 to rotate. The relationship between the drive toothed roller 64 and the top ring tooth 5 is used to drive the sleeve frame 61 to move on the top ring track 4.

[0047] 4. Then, the drive device 6 drives the hanging plate 7 and the camera 8 at the lower end of the hanging plate 7 to make circular motion around the patient;

[0048] 5. The imaging device 8 is aligned with the imaging port 103 to image the patient's internal organs;

[0049] 6. During the imaging process, the patient stands behind the radiation shielding device 10, leaving only the imaging port 103 located in the direction of the patient's abdomen or chest. The outer iron plate 101 and the inner lead plate 102 are used to achieve double interception of X-rays, shielding the effects of X-rays on other parts of the human body, thereby greatly reducing the radiation impact on the patient's body.

[0050] 7. By having the camera 8 move in a circular motion around the patient, a 360-degree all-around image of the patient standing on the standing board 2 can be captured without any blind spots, thereby greatly improving the comprehensiveness and accuracy of the patient's image data.

[0051] 8. Since the outer panel 101 is equipped with a connecting arm 11 that is fixedly connected to the hanging plate 7, when the camera 8 is moved by the hanging plate 7, the anti-radiation device 10 will also rotate synchronously, so that the anti-radiation device 10 can always ensure the interception of excess radiation from the camera 8.

[0052] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
