Description

Technical Field

[0001] This invention relates to the field of image reading devices, and more specifically, to an adaptive image reading device for medical imaging films. Background Technology

[0002] Medical imaging films are physical films created by recording information about the internal structure of the human body onto photosensitive materials using medical imaging technologies such as X-ray photography, computed tomography, and magnetic resonance imaging. The film consists of a flexible, transparent substrate coated with a photosensitive emulsion layer. After exposure and development, a grayscale image composed of silver particles of varying densities is formed on the film. The differences in density correspond to the different degrees of radiation absorption by the tissue being imaged, thus reflecting its anatomical structure and pathological changes. Reading the films requires a reading device, which is essentially a lightbox. Its core working principle is backlighting. The box contains a uniformly distributed light source, covered by a diffuser plate in front. This diffuser plate transforms point or line light sources into uniform surface light sources. The doctor attaches the film directly to the diffuser plate surface. Light passes through the film from behind, and its intensity attenuates to varying degrees due to the different densities in different areas of the film, allowing the human eye to clearly discern the grayscale image recorded on the film.

[0003] Traditional devices have a rigid plane observation interface, while optical films are prone to bending and curling during storage. Forcing the deformed optical film flattened onto a rigid plane introduces internal stress, causing significant geometric distortion of the image and affecting measurement accuracy. At the same time, the uneven surface can cause reflected glare, which seriously interferes with observation. Moreover, such devices are usually mounted on the wall, requiring the user to tilt their head for extended periods when reading the film, affecting comfort. To solve these problems, this application proposes a novel adaptive optical film reading device for medical imaging. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive medical imaging film reading device to solve the problems mentioned in the background art: by adjusting the distance and angle of the front shell, the film reading is made easier, eliminating the need to tilt the head to view the film; the flexible contact can reduce the bending of the film by squeezing it, and will not cause stress concentration on the film as with rigid squeezing; the distance telescopic rod pulls the shell, thereby adjusting the distance between the shell and the film and improving the image clarity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An adaptive medical imaging film reading device includes an adjustment mechanism, a front shell, two first correction mechanisms and two second correction mechanisms. The front shell end face is provided with two limiting mechanisms, a moving mechanism, and a fixing mechanism. Multiple lighting mechanisms are provided inside the front shell. The adjustment mechanism includes a rear shell and a guide rail. Four main robotic arms are installed inside the rear shell. A slider is installed at the outer end of the guide rail. A universal ball joint is installed inside the slider. An elliptical plate is installed at the outer end of the universal ball joint. The two second correction mechanisms include two support shells and multiple micro stepper motors. Each of the output ends of the multiple micro stepper motors is provided with a compression screw. Each of the outer ends of the multiple compression screws is provided with a nut. Each of the end faces of the multiple nuts is provided with a pressure sensor. Each of the end faces of the multiple pressure sensors is provided with a flexible contact. The multiple lighting mechanisms include multiple housings and multiple baffles. Each of the multiple housings has a distance telescopic rod connected to its end face, and each of the multiple housings has multiple lamp blocks inside.

[0006] By adopting the above technical solution and adjusting the distance and angle of the front shell, reading the film becomes easier, eliminating the need to constantly tilt the head to watch. Flexible contact extrusion of the light sheet can reduce its bending and will not cause stress concentration in the light sheet as in rigid extrusion. The telescopic rod pulls the housing, thereby adjusting the distance between the housing and the light sheet and improving image clarity.

[0007] Preferably, a light-transmitting plate is provided inside the front shell, and both the moving mechanism and the fixing mechanism are disposed between the two limiting mechanisms.

[0008] By adopting the above technical solution, the light film is placed against the light-transmitting plate, and the light source can pass through the light-transmitting plate to illuminate the light film, which makes it convenient for doctors to view the light film. Moreover, the light films of different sizes can be clamped and viewed by the cooperation of the moving mechanism and the fixing mechanism.

[0009] Preferably, the moving mechanism and the fixing mechanism have the same design structure, and the first correction mechanism and the second correction mechanism have the same design structure.

[0010] By adopting the above technical solution, the moving mechanism and the fixed mechanism have the same structure, but the two structures are symmetrically arranged. The moving mechanism can move downward to clamp the light sheet placed on the fixed mechanism. Moreover, the first correction mechanism is fixed on both sides and can correct both sides of the light sheet. The second correction mechanism is set on the fixed mechanism and the moving mechanism and corrects the upper and lower sides of the light sheet. This correction plays the main correction role.

[0011] Preferably, each of the four main robotic arms is connected to a secondary robotic arm, each of the four secondary robotic arms is connected to a connecting rod, each of the four connecting rods is disposed on the inner wall of the elliptical plate, and each of the guide rail end faces is connected to a connecting plate.

[0012] By adopting the above technical solution, the auxiliary robotic arm connected to the main robotic arm can rotate and swing, thus moving with the front shell. The auxiliary robotic arm is connected by a connecting rod and an elliptical plate, which is fitted onto the universal ball joint, so that the elliptical plate can support the front shell.

[0013] Preferably, the two limiting mechanisms include two side plates, each side plate end face is provided with a moving stepper motor, and each moving stepper motor output end is provided with a moving lead screw.

[0014] By adopting the above technical solution, the moving stepper motor can drive the moving screw to rotate. The rotating moving screw will drive the moving mechanism to move in front of the front shell, so that the moving mechanism can approach the light sheet and then realize the clamping and correction of the light sheet. The moving mechanism is restricted to the moving position by the side plate.

[0015] Preferably, each of the two side plates has a movable groove on its end face, and the two movable lead screws are respectively disposed inside the two movable grooves.

[0016] By adopting the above technical solution, the protruding part of the moving mechanism is set inside the moving groove, and can be moved by the moving screw, thereby completing the downward movement of the moving mechanism.

[0017] Preferably, the moving mechanism includes a plate body, an object detection plate is disposed inside the plate body, and the support shell is disposed inside the plate body.

[0018] By adopting the above technical solution, an object detection plate is set inside the moving mechanism, and the same fixed mechanism is also set inside the moving mechanism. The object detection plate can detect whether there is a light sheet placed inside, which facilitates the movement of the moving mechanism.

[0019] Preferably, each of the two support shell end faces is provided with a plurality of placement slots, a plurality of micro stepper motors are respectively disposed on the inner wall of the plurality of placement slots, and a plurality of flexible contacts are respectively disposed inside the plurality of placement slots.

[0020] By adopting the above technical solution, a micro stepper motor drives the extrusion screw to rotate. The rotating extrusion screw drives the flexible contact to move through the nut, thereby extruding the light sheet and smoothing it out without damaging it.

[0021] Preferably, each of the multiple baffle end faces is provided with an adjustment plate, and each of the multiple housing end faces is provided with two miniature telescopic rods.

[0022] By adopting the above technical solution, when it is necessary to adjust the illumination range of the lamp block, the miniature telescopic rod pulls the adjustment plate, which in turn pulls the baffle, thereby forming the control of the baffle by the miniature telescopic rod.

[0023] Preferably, the output ends of the plurality of miniature telescopic rods are respectively connected to the plurality of adjustment plates, and the plurality of baffles are respectively disposed inside the plurality of housings.

[0024] By adopting the above technical solution, the miniature telescopic rod can move the baffle inside the housing through the adjustment plate, thereby blocking the illumination of the lamp block.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1) When using this film reading device, the rear shell is equipped with a main robotic arm. When it is necessary to read the film, place the film on the front shell and manually pull the front shell. The front shell is supported by the robotic arm, allowing it to move outward. Moreover, the angle of the front shell can be swung by the connection of the universal ball and the slider, thereby adjusting the angle of the film reading, making the film reading easier and eliminating the need to tilt the head to watch.

[0026] 2) When using this reading device, the device is equipped with a correction mechanism. When the optical sheet is placed on the front shell, the micro stepper motor will drive the pressure sensor and flexible contact to press on the optical sheet through the nut. The different pressure conditions transmitted by the pressure sensor can indicate where the optical sheet is deformed and bent. The flexible contact can reduce the bending of the optical sheet by squeezing it. Moreover, the flexible contact will not damage the surface of the optical sheet and will not cause stress concentration on the optical sheet like rigid squeezing.

[0027] 3) When this film reading device is in use, it will transmit information to the illumination mechanism when the film is detected to be deformed or bent in front of it. When the illumination mechanism receives the information, it will notify the distance telescopic rod to pull the housing, thereby adjusting the distance between the housing and the film, improving the image clarity. In addition, the illumination range on both sides of the lamp block can be adjusted by the baffle, making it convenient for doctors to view the image of the bent part of the film.

[0030] Example 1, please refer to Figure 1 and Figure 2 An adaptive medical imaging film reading device includes an adjustment mechanism 1, a front shell 2, two first correction mechanisms 4 and two second correction mechanisms 6. Two limiting mechanisms 3 are provided on the end face of the front shell 2, a moving mechanism 5 is provided on the end face of the front shell 2, a fixing mechanism 9 is provided on the end face of the front shell 2, and multiple lighting mechanisms 8 are provided inside the front shell 2. The distance of the front shell 2 can be adjusted through the cooperation of multiple structures, and the film can be smoothed and the illumination of the light source can be adjusted.

[0031] Specifically, a light-transmitting plate 7 is provided inside the front shell 2, and the moving mechanism 5 and the fixing mechanism 9 are both located between the two limiting mechanisms 3. The moving mechanism 5 and the fixing mechanism 9 have the same design structure, and the first correction mechanism 4 and the second correction mechanism 6 have the same design structure.

[0032] Furthermore, two limiting mechanisms 3 are fixedly installed on both sides of the front end face of the front shell 2, a moving mechanism 5 is slidably installed on the upper side of the front end face of the front shell 2, a fixing mechanism 9 is fixedly installed on the lower side of the front end face of the front shell 2, an illumination mechanism 8 is fixedly installed inside the front shell 2, a light-transmitting plate 7 is fixedly installed on the front side of the inner wall of the front shell 2, a moving mechanism 5 is slidably installed between the two limiting mechanisms 3, a fixing mechanism 9 is fixedly installed between the two limiting mechanisms 3, two first correction mechanisms 4 are embedded on both sides of the front end face of the front shell 2, two first correction mechanisms 4 are located on the rear side of the two limiting mechanisms 3, and two second correction mechanisms 6 are embedded in the moving mechanism 5 and the fixing mechanism 9 respectively. The mechanisms inside the device are electrically connected.

[0033] The steps of using this invention are as follows: Place the light sheet on the fixing mechanism 9, and move the moving mechanism 5 downward to the upper edge of the light sheet. At this time, the first correction mechanism 4 and the second correction mechanism 6 are activated simultaneously to clamp the light sheet and correct its bending position. The data generated by the correction is transmitted to the lighting mechanism 8, which changes the intensity and distance of the lamp irradiated by the lighting mechanism 8. After the clamping is stable, the front shell 2 can be pulled out. The front shell 2 can be pulled out and its angle can be adjusted with the support of the rear shell 101.

[0034] Example 2, please refer to Figures 2 to 4 The difference from the basic embodiment 1 is that the adjustment mechanism 1 includes a rear shell 101 and a guide rail 104. The rear shell 101 is equipped with four main mechanical arms 102. The guide rail 104 is equipped with a slider 105 at its outer end. The slider 105 is equipped with a universal ball joint 106 inside its interior. The universal ball joint 106 is equipped with an elliptical plate 107 at its outer end.

[0035] Specifically, each of the four main robotic arms 102 is connected to a secondary robotic arm 109, each of the four secondary robotic arms 109 is connected to a connecting rod 108, each of the four connecting rods 108 is set on the inner wall of the elliptical plate 107, and each of the end faces of the guide rail 104 is connected to a connecting plate 103.

[0036] Furthermore, four main robotic arms 102 are rotatably mounted on both sides of the inner bottom and inner top surfaces of the rear shell 101, respectively. Four auxiliary robotic arms 109 are connected to the four main robotic arms 102 via damping. Four connecting rods 108 are fixedly mounted on the rear end faces of the four auxiliary robotic arms 109, respectively. A connecting plate 103 is slidably mounted inside the rear shell 101 and is fixedly connected to the front shell 2. A guide rail 104 is fixedly mounted in the middle of the rear end face of the connecting plate 103. A slider 105 is slidably mounted on the outer end face of the guide rail 104 via damping. A universal ball joint 106 is rotatably mounted inside the slider 105 via damping. An elliptical plate 107 is fixedly mounted on the rear side of the outer end face of the universal ball joint 106. Connecting rods 108 are fixedly mounted on the upper and lower sides of the outer end face of the elliptical plate 107. All structures are connected by damping and will not shift when no external force is applied.

[0037] The steps of using this invention are as follows: By pulling the front shell 2, the front shell 2 will pull the slider 105 through the connecting plate 103 and the guide rail 104. The slider 105 will pull the elliptical plate 107 through the universal ball joint 106. The elliptical plate 107 will pull the robotic arm through the connecting rod 108, causing the main robotic arm 102 and the auxiliary robotic arm 109 to deform and leave the interior of the rear shell 101. Moreover, by swinging the front shell 2, the front shell 2 will drive the slider 105 on the guide rail 104 to deform through the connecting plate 103. Furthermore, since the universal ball joint 106 used can be changed at multiple angles and can also be rotated, it is convenient to view from multiple angles.

[0038] Example 3, please refer to Figure 2 The difference from embodiment 2 is that the two limiting mechanisms 3 include two side plates 301, each side plate 301 has a moving stepper motor 304 on its end face, and each moving stepper motor 304 has a moving lead screw 303 at its output end.

[0039] Specifically, each of the two side plates 301 has a moving groove 302 on its end face, and two moving screws 303 are respectively set inside the two moving grooves 302.

[0040] Furthermore, the moving stepper motor 304 is fixedly mounted on the upper end face of the side plate 301, and two moving slots 302 are opened on the opposite end faces of the two side plates 301. Two moving screws 303 are respectively rotatably mounted on the bottom and top surfaces of the two moving slots 302. The output end of the moving stepper motor 304 is fixedly mounted on the upper end face of the moving screw 303. The moving mechanism 5 has a protruding block that is located inside the moving slot 302, so that the moving screw 303 can drive the moving mechanism 5 to move. Moreover, the lower end of the moving screw 303 is not threaded to avoid driving the fixed mechanism 9 to move.

[0041] The steps of using this invention are as follows: Start the moving stepper motor 304 to drive the moving lead screw 303 to rotate. The rotating moving lead screw 303 will drive the moving mechanism 5 to move downward, so that the moving mechanism 5 gradually approaches the light sheet and can clamp the light sheet, which is convenient for clamping light sheets of different sizes.

[0042] Example 4, please refer to Figure 5 The difference from embodiment 3 is that the moving mechanism 5 includes a plate body 501, an object detection plate 502 is provided inside the plate body 501, and a support shell 601 is provided inside the plate body 501.

[0043] Furthermore, the object detection plate 502 is embedded in the top surface of the plate body 501. The object detection plate 502 is equipped with an infrared sensor, which enables the object detection plate 502 to detect the presence of the light sheet. Moreover, the support shell 601 is embedded in the inner wall of the front side of the object, so that the internal structure of the support shell 601 can squeeze and correct the light sheet.

[0044] The steps of using this invention are as follows: Place the light sheet on the fixing mechanism 9. When the object detection plate 502 detects the light sheet, the object detection plate 502 on the moving mechanism 5 will not detect the light sheet and will be driven downward by the limiting mechanism 3 so that the moving mechanism 5 reaches the position above the light sheet. At this time, it will be detected by the object detection plate 502 on the moving mechanism 5 and will be notified to stop in time to start the correction work.

[0045] Example 5, please refer to Figure 6 and Figure 7 The difference from the basic embodiment 4 is that the two second correction mechanisms 6 include two support shells 601 and multiple micro stepper motors 604. Each of the multiple micro stepper motors 604 is provided with a compression screw 607 at its output end. Each of the multiple compression screws 607 is provided with a nut 605 at its outer end. Each of the multiple nuts 605 is provided with a pressure sensor 606 at its end face. Each of the multiple pressure sensors 606 is provided with a flexible contact 603 at its end face.

[0046] Specifically, multiple placement slots 602 are provided on the end faces of the two support shells 601, multiple micro stepper motors 604 are respectively disposed on the inner walls of the multiple placement slots 602, and multiple flexible contacts 603 are respectively disposed inside the multiple placement slots 602.

[0047] Furthermore, multiple placement slots 602 are equidistantly opened on the rear end face of the support shell 601. A micro stepper motor 604 is fixedly installed on the inner wall of the front side of the placement slot 602. A compression screw 607 is fixedly installed on the output end of the micro stepper motor 604. A nut 605 is threadedly sleeved on the front side of the outer end face of the compression screw 607. A pressure sensor 606 is fixedly installed on the rear end face of the nut 605. The pressure sensor 606 is sleeved on the outer end of the compression screw 607. A flexible contact 603 is fixedly installed on the rear end face of the pressure sensor 606. The flexible contact 603 is sleeved on the outer end face of the compression screw 607 and slidably sleeved inside the placement slot 602.

[0048] The steps of using this invention are as follows: During correction, the micro stepper motor 604 is started to drive the extrusion screw 607 to rotate. The rotating extrusion screw 607 pushes the pressure sensor 606 through the nut 605, so that the pressure sensor 606 can push the flexible contact 603 to press against the outer end of the optical sheet, thereby smoothing the bent part of the optical sheet. Moreover, the flexible contact 603 will not damage the surface of the optical sheet. Furthermore, the extrusion of multiple flexible contacts 603 can avoid stress concentration on the optical sheet and increase the stability of the optical sheet placement.

[0049] Example 6, please refer to Figures 8 to 10 The difference from embodiment 5 is that the multiple lighting mechanisms 8 include multiple housings 801 and multiple baffles 803, each housing 801 has a distance telescopic rod 804 connected to its end face, and each housing 801 has multiple lamp blocks 802 inside it.

[0050] Specifically, each of the multiple baffles 803 has an adjustment plate 806 on its end face, and each of the multiple housings 801 has two miniature telescopic rods 805 on its end face. The output ends of the multiple miniature telescopic rods 805 are respectively connected to the multiple adjustment plates 806, and the multiple baffles 803 are respectively located inside the multiple housings 801.

[0051] Furthermore, multiple lighting mechanisms 8 are equidistantly placed inside the front housing 2. The output end of the distance telescopic rod 804 is connected to the middle position of the rear end face of the housing 801. The distance telescopic rod 804 is fixedly set in the middle position of the rear inner wall of the front housing 2. Multiple lamp blocks 802 are equidistantly fixedly set in the rear inner wall of the housing 801. The baffle 803 is slidably set in the inner walls on both sides of the housing 801. Two miniature telescopic rods 805 are fixedly set in the upper and lower positions of the rear end face of the housing 801, respectively. The two miniature telescopic rods 805 are symmetrically arranged, and their output ends are both set towards the middle. Two adjusting plates 806 are fixedly set on the two baffles 803, respectively set above and below one of the two baffles 803. The output end of the miniature electric telescopic rod is fixedly set in the end face of the adjusting plate 806.

[0052] The steps of using this invention are as follows: When the correction mechanism receives information, it notifies the lighting mechanism 8 to make adjustments. When adjustment is needed, the distance telescopic rod 804 is activated to pull the housing 801, causing the housing 801 to move inside the front housing 2. This allows adjustment of the distance between the lamp block 802 and the light-transmitting plate 7. By changing the distance, the effect of the light illumination can be changed. Moreover, activating the micro electric telescopic rod can pull the baffle 803 through the adjustment plate 806, so that the baffle 803 can block the front of the lamp block 802, thereby changing the illumination of the lamp block 802. Furthermore, by activating different micro electric telescopic rods, different sides of the baffle 803 can be pulled to achieve different adjustments, which is convenient for adjustment according to the curvature of the light sheet.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
