Description

Technical Field

[0001] This utility model relates to the field of adjustment structure technology, specifically a freely adjustable structure for reading medical images. Background Technology

[0002] Medical image interpretation is a crucial step in clinical diagnosis. Doctors rely on various medical imaging data, such as CT scans, MRIs, and X-rays, to meticulously observe lesion characteristics and tissue morphology, providing core evidence for disease diagnosis. The accuracy of this interpretation directly impacts subsequent treatment plans and patient outcomes. In this process, the image interpretation equipment, as the core carrier of the image, plays a vital role. Whether its orientation and angle are suitable for the doctor's viewing posture and perspective significantly affects the doctor's comfort, concentration, and diagnostic efficiency.

[0003] To meet the different usage habits of doctors, the viewing needs of different image reading scenarios, and to avoid physical fatigue caused by doctors maintaining a fixed posture for a long time, it is usually necessary to use a medical image reading adjustable structure to flexibly adjust the orientation and position of the reading equipment so that the reading equipment can be presented to the doctor at a better angle, creating favorable conditions for efficient and accurate image reading.

[0004] Currently available medical image viewing adjustment mechanisms still have significant shortcomings in practical applications. Most adjustment mechanisms can only achieve preliminary adjustment of the viewing device's angle. After adjusting the viewing device to the doctor's desired angle, there is a lack of a reliable position locking mechanism to fix the adjusted state. When the viewing device is pushed by external forces (such as accidental bumping or environmental vibration), its adjusted angle is easily changed, causing the image presentation angle to deviate from the doctor's optimal viewing angle.

[0005] This variable angle issue brings many inconveniences to doctors' image interpretation work: on the one hand, if the equipment angle shifts due to external force during image interpretation, the doctor needs to interrupt the current interpretation process to readjust the angle, disrupting the treatment rhythm and affecting diagnostic efficiency; on the other hand, when using the image interpretation equipment again, doctors often need to spend time adjusting the equipment angle again, and cannot directly use the previously adapted angle, which increases unnecessary operation steps, not only reducing work efficiency, but also potentially affecting the consistency of the image interpretation perspective due to errors in the repeated adjustment process, which may have a potential impact on the accuracy of diagnosis. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a freely adjustable structure for medical image reading.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A freely adjustable structure for reading medical images, comprising:

[0009] U-shaped base;

[0010] The film viewing device is rotatably mounted on the inside of the U-shaped base via a rotating shaft;

[0011] A pair of limiting plates are fixed to the circumference of the rotating shaft, and the pair of limiting plates are arranged horizontally;

[0012] A pair of limiting pins pass through the U-shaped base and are inserted into both sides of the limiting piece. The limiting pins are provided with a non-insertion end and an insertion end.

[0013] Multiple pin holes are arranged in a circumferential array on the U-shaped base and located on the rotation path of the limiting piece;

[0014] The projection of the pin hole on the film reading device is located within the rotation path of the limiting piece, and the tilt angle of the film reading device is adjusted by inserting the pair of limiting pins into different pin holes.

[0015] Furthermore, the center of gravity of the film reading device is located above the rotating shaft, so that when the film reading device is touched and rotated, it can automatically return to the angle limited by the limiting pin.

[0016] Preferred options also include:

[0017] A paramagnetic sheet is fixed to the non-plug end of the pair of limiting pins;

[0018] A permanent magnet sheet is fixed on the outside of the U-shaped base at the position corresponding to the rotating shaft. After a pair of limiting pins are inserted, the paramagnetic sheet and the permanent magnet sheet are arranged opposite to each other.

[0019] When the pair of limiting pins are inserted into the pin holes, the permanent magnet generates an attractive force on the paramagnetic sheet, forming a structure that restricts the axial direction of the limiting pins.

[0020] Preferably, a counterweight is connected to the top of the rear end of the film viewing device via a traction rope. The traction rope extends and passes through the top of the front end of the film viewing device. A movable image clip is installed inside the film viewing device via the traction rope. A fixed image clip is provided at the bottom of the front end of the film viewing device. The counterweight changes the center of gravity of the film viewing device to be above the rotating shaft. The counterweight forms tension on the film through the traction rope and the movable image clip.

[0021] Preferably, an elastic element is provided at the contact position between the limiting piece and the pair of limiting pins.

[0022] Preferably, the elastic element is an elastic sheet or rubber.

[0023] Preferably, a limiting block is installed on the top of the front end of the U-shaped base. The limiting block is located on the path of the viewing device rotating toward the observer, forming a limiting structure for the viewing device rotating toward the observer.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. The counterweight structure at the top rear of the film reading device ensures that the center of gravity of the film reading device is above the rotating shaft. When the device is touched and rotated and the external force is removed, it can automatically rotate around the rotating shaft to reset under the action of gravity until it is limited to the initial angle by the limit pin. No manual intervention is required, which can quickly restore the normal use of the device, reduce the cumbersome operation, and improve the convenience and efficiency of use.

[0026] 2. By changing the center of gravity of the film viewing device through the counterweight, the film viewing device can have a restoring force to return to its original position by its own weight after rotation. At the same time, the counterweight can also work with the traction rope and the moving image clamp to pull the top of the film, while the fixed image clamp pulls the bottom of the film. The clamping force of the fixed image clamp is greater than the tension force of the film pulled by the counterweight, so that the film is in a taut state, which makes it easier for the operator to observe.

[0027] 3. The elastic element (elastic sheet or rubber) structure at the contact point between the limiting piece and the limiting pin: on the one hand, it buffers the impact force when the limiting pin and the limiting piece come into contact, reduces collision wear, and extends the service life of the components; on the other hand, the elasticity enhances the fit between the two, improves the fixing effect, and prevents the reading equipment from angular displacement due to slight vibration.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0036] Example

[0037] like Figure 1-5 As shown, a freely adjustable structure for reading medical images includes:

[0038] U-shaped base 1: Serves as the supporting foundation of the entire structure, providing an installation carrier for other components and ensuring the stability of the overall structure; a limit block is installed at the top front end of the base, which is located on the path of the viewing device 2 rotating toward the observer, effectively restricting the viewing device 2 from rotating toward the observer and limiting the viewing device 2 to only rotating in the vertical direction toward the observer.

[0039] Image viewing device 2: Used to place and display medical images for medical staff to review. It is rotatably mounted on the inside of the U-shaped base 1 via a rotating shaft 3, and its tilt angle can be adjusted around the rotating shaft 3. A counterweight is provided at the top of the rear end of the image viewing device 2. The center of gravity of the image viewing device 2 is located above the rotating shaft 3. This design allows the image viewing device 2 to automatically return to the angle limited by the limit pin 5 when it is touched and rotated, reducing manual reset operations and improving ease of use.

[0040] Rotating shaft 3: A key component connecting the U-shaped base 1 and the film reading device 2, providing support for the rotation of the film reading device 2, ensuring the smoothness and stability of the film reading device 2 during rotation, and is the core rotating component for realizing the tilt angle adjustment of the film reading device 2.

[0041] A pair of limiting plates 4: fixed circumferentially to the rotating shaft 3, and horizontally arranged. An elastic element is provided at the contact point between the limiting plates 4 and the pair of limiting pins 5; the elastic element can be made of elastic sheet or rubber. The elastic element acts as a buffer when the limiting pins 5 and limiting plates 4 contact, reducing collision and wear between them, while also enhancing the fixing effect of the limiting pins 5 on the limiting plates 4, ensuring the stability of the reading device 2 after angle adjustment.

[0042] A pair of limiting pins 5: passing through the U-shaped base 1 and inserted into both sides of the limiting piece 4. The limiting pins 5 have non-insertion ends and insertion ends. The limiting pins 5 are key components for fixing the angle of the film reading device 2. By inserting them into different pin holes 6, the position of the limiting piece 4 can be limited, thereby fixing the tilt angle of the film reading device 2.

[0043] Multiple pin holes 6 are arranged in a circumferential array on the U-shaped base 1 and located on the rotation path of the limiting piece 4. The projection of the pin holes 6 on the reading device 2 is located within the rotation path of the limiting piece 4. By inserting a pair of limiting pins 5 into different pin holes 6, the fixed position of the limiting piece 4 can be changed, thereby adjusting the tilt angle of the reading device 2 to meet the different reading angle needs of medical staff.

[0044] Paramagnetic sheet 7: Fixed to the non-insertion end of a pair of limit pins 5, used in conjunction with permanent magnet sheet 8, to enhance the fixing effect of limit pins 5.

[0045] Permanent magnet 8: Fixed on the outside of the U-shaped base 1 at the position corresponding to the rotating shaft 3. When a pair of limiting pins 5 are inserted into the pin hole 6, the paramagnetic sheet 7 and the permanent magnet 8 are arranged opposite each other. The permanent magnet 8 generates an attraction force on the paramagnetic sheet 7, forming a limiting structure for the axial movement of the limiting pin 5. This can effectively prevent the limiting pin 5 from loosening or falling off during use, and further ensure the stability of the angle of the reading device 2.

[0046] A counterweight 9 is connected to the top of the rear end of the film viewing device 2 via a traction rope. The traction rope extends and passes through the top of the front end of the film viewing device 2. A movable image clip 10 is installed inside the film viewing device 2 via the traction rope. A fixed image clip 11 is provided at the bottom of the front end of the film viewing device 2. The counterweight 9 changes the center of gravity of the film viewing device 2 so that it is located above the rotating shaft 3. The counterweight 9 forms a tension force on the film through the traction rope and the movable image clip 10. By changing the center of gravity of the film viewing device 2 through the counterweight 9, the film viewing device 2 has a restoring force that can return to its original position by its own weight after rotation. At the same time, the counterweight 9 can also work with the traction rope and the movable image clip 10 to pull the top of the film, while the fixed image clip 11 pulls the bottom of the film. The clamping force of the fixed image clip 11 is greater than the tension force of the film pulled by the counterweight 9, so that the film is in a taut state, which is convenient for the operator to observe.

[0047] I. Angle Adjustment Trigger and Preparation: When medical staff need to adjust the tilt angle of the image reading device 2 to adapt to different image reading needs, the current fixed angle must first be released. At this time, the operator holds the non-insertion end of the limit pin 5 and applies outward pulling force. Since the non-insertion end of the limit pin 5 is fixed with a paramagnetic piece 7, and the outer side of the U-shaped base 1 is fixed with a permanent magnet piece 8 corresponding to the position of the rotating shaft 3, in the initial state, the permanent magnet piece 8 generates an attraction force on the paramagnetic piece 7, forming an axial restriction on the limit pin 5. Therefore, the operator must overcome this attraction force to pull the limit pin 5 out of the currently inserted pin hole 6, so that the limit pin 5 is disengaged from the insertion cooperation with the limit piece 4, releasing the position restriction on the limit piece 4, and preparing for the rotation adjustment of the image reading device 2.

[0048] II. Angle Adjustment Process of the Reading Device: After the limiting pin 5 releases the limiting piece 4, the operator can gently push the edge of the reading device 2 to drive it to rotate around the rotating shaft 3. Since the rotating shaft 3 is a key component connecting the U-shaped base 1 and the reading device 2, it provides stable support for the rotation of the reading device 2, ensuring smooth rotation without significant jamming. Simultaneously, a pair of horizontally arranged limiting pieces 4 fixed to the circumference of the rotating shaft 3 will rotate synchronously with the rotating shaft 3 and the reading device 2. The limiting pieces 4 are always within the rotation path range of the multiple circumferentially arrayed pin holes 6 on the U-shaped base 1, providing a suitable basis for the insertion of the limiting pin 5 when fixing the angle later.

[0049] During this process, the limiting block installed at the top front end of the U-shaped base 1 restricts the rotation range of the film reading device 2. When the film reading device 2 rotates towards the observer, the limiting block prevents it from rotating further, ensuring that the film reading device 2 can only rotate vertically towards the observer, avoiding damage to the equipment or affecting the film reading operation due to excessive rotation, and ensuring the safety and rationality of the adjustment process.

[0050] III. Angle Fixation and Stability Enhancement: After the image reading device 2 is rotated to the tilt angle required by the medical staff, the operator aligns the limiting pin 5 with the corresponding pin holes 6 on both sides of the limiting plate 4 at the current angle, and pushes the limiting pin 5 inward so that it passes through the U-shaped base 1 and is re-inserted into the pin holes 6 on both sides of the limiting plate 4. At this time, the limiting pin 5 limits the position of the limiting plate 4. Since the limiting plate 4 is fixedly connected to the rotating shaft 3, the rotation of the rotating shaft 3 is restricted, ultimately limiting the image reading device 2 between the target tilt angle and the vertical direction.

[0051] Meanwhile, an elastic element (elastic sheet or rubber material) is provided at the contact position between the limiting piece 4 and the limiting pin 5. The elastic element will undergo slight deformation during the insertion of the limiting pin 5. On the one hand, it can buffer the impact force when the limiting pin 5 and the limiting piece 4 come into contact, reduce the collision and wear between the two, and extend the service life of the components. On the other hand, the elastic force of the elastic element will enhance the fit between the limiting pin 5 and the limiting piece 4, further improve the fixing effect of the limiting piece 4, and prevent the viewing device 2 from angular displacement due to slight vibration during use.

[0052] In addition, after the limit pin 5 is inserted, the paramagnetic plate 7 at its non-insertion end and the permanent magnet plate 8 on the outside of the U-shaped base 1 are repositioned relative to each other. The permanent magnet plate 8 once again generates a stable attraction force on the paramagnetic plate 7, forming a strong axial restriction structure for the limit pin 5. This effectively prevents the limit pin 5 from becoming axially loose or falling off due to accidental contact during use. It ensures the stability of the angle fixation of the image reading device 2 from multiple dimensions, ensuring that medical staff can perform image reading work with peace of mind.

[0053] IV. Automatic Reset Mechanism After Contact: During film reading, if the film reading device 2 is accidentally touched and rotates, a counterweight at the top rear end ensures that the center of gravity of the film reading device 2 falls precisely above the rotating shaft 3. When the external force disappears, under the influence of gravity, the film reading device 2 will automatically rotate around the rotating shaft 3 in the direction of stable center of gravity until the limiting plate 4 and the limiting pin 5 re-contact and are positioned by the limiting pin 5, ultimately automatically resetting the film reading device 2 to the initial angle fixed by the limiting pin 5. This automatic reset mechanism requires no manual intervention, quickly restoring the film reading device to its normal operating state, reducing the tediousness of manual reset operations, and further improving the convenience and efficiency of equipment use.

[0054] Through the cooperative structure of the limiting pin 5, the paramagnetic plate 7, and the permanent magnet plate 8: during the angle adjustment preparation stage, the permanent magnet plate 8 generates an attractive force on the paramagnetic plate 7, which restricts the axial direction of the limiting pin 5, ensuring that the limiting pin 5 is stably inserted in the non-adjustment state and preventing the angle of the reading device 2 from shifting; during adjustment, the operator can overcome the attractive force to pull out the limiting pin 5 to release the fixation, realizing flexible switching between fixed states and providing a convenient triggering method for angle adjustment.

[0055] Through the coordinated structure of the rotating shaft 3 and the limiting piece 4: the rotating shaft 3 provides stable support for the rotation of the image reading device 2, ensuring smooth rotation without jamming; the limiting piece 4 rotates synchronously with the rotating shaft 3 and is within the rotation path of the pin hole 6, providing a suitable foundation for the subsequent insertion and fixing of the limiting pin 5, together realizing the flexible adjustment of the tilt angle of the image reading device 2 to meet the different image reading angle needs of medical staff.

[0056] The limiting block structure at the top front of the U-shaped base 1 can prevent the film reading device 2 from rotating excessively towards the observer, ensuring that it can only rotate to the vertical direction. This avoids damage to the device or interference with the film reading operation due to excessive rotation, and ensures the safety and rationality of the angle adjustment process.

[0057] Through the insertion and fixing structure of the limiting pin 5, pin hole 6 and limiting piece 4: when the reading device 2 is adjusted to the target angle, the limiting pin 5 is inserted into the corresponding pin hole 6 and the position of the limiting piece 4 is limited, thereby restricting the rotation of the rotating shaft 3 and fixing the reading device 2 between the target tilt angle and the vertical direction, so as to achieve precise angle fixing.

[0058] The elastic element (elastic sheet or rubber) at the contact point between the limiting piece 4 and the limiting pin 5 serves two purposes: firstly, it buffers the impact force when the limiting pin 5 contacts the limiting piece 4, reducing collision wear and extending the service life of the components; secondly, it enhances the fit between the two through elasticity, improving the fixing effect and preventing the reading device 2 from shifting at an angle due to slight vibration.

[0059] Through the attraction structure of the paramagnetic sheet 7 and the permanent magnet sheet 8 (after the angle is fixed): After the limiting pin 5 is inserted, the permanent magnet sheet 8 generates a stable attraction to the paramagnetic sheet 7, forming a strong axial restriction on the limiting pin 5, effectively preventing the limiting pin 5 from axial loosening or falling off due to accidental contact, ensuring the stability of the angle of the image reading device 2 from multiple dimensions, allowing medical staff to read images with peace of mind.

[0060] The counterweight structure at the top rear of the film reading device 2 ensures that the center of gravity of the film reading device 2 falls above the rotating shaft 3. When the device is touched and rotated and the external force disappears, it can automatically rotate around the rotating shaft 3 and reset under the action of gravity until it is limited to the initial angle by the limit pin 5. No manual intervention is required, and the device can quickly return to normal operation, reducing the complexity of operation and improving the convenience and efficiency of use.

[0061] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
