However, to ensure that the X-rays can accurately irradiate the target area, the positioning accuracy of the X-ray machine is extremely high. Traditional X-ray machine positioning methods usually rely on the doctor's experience and visual judgment, which is largely limited by the doctor's skills and external environment.
[0003] In recent years, with the rapid development of laser technology, laser positioning has been widely used in the medical field due to its high precision and intuitiveness. The high directionality and high brightness of the laser beam enable it to be accurately projected at the target location, providing doctors with an intuitive and accurate positioning reference.
[0004] Although laser positioning technology has been applied in the field of medical imaging, there are still some technical challenges. For example, how to achieve fast and accurate alignment between the X-ray machine and the laser emitter while ensuring positioning accuracy to improve detection efficiency is still a major problem in current medical imaging technology.
[0005] To address this problem, some X-ray machine laser alignment devices have appeared on the market, which have improved positioning accuracy and efficiency to a certain extent. However, the existing devices still have many deficiencies in structural design and function, such as cumbersome adjustment process and unstable positioning accuracy, which limits their wide application in the medical field.
[0006] In the prior art, the laser emission positioner and the X-ray machine body are set separately, so additional positioning and calibration steps may be required before X-ray irradiation, which increases the time from laser positioning to X-ray irradiation.
[0007] To this end, we proposed a laser alignment device for an X-ray machine without the need for additional positioning steps, which can significantly reduce the time between laser positioning and X-ray irradiation, thereby improving work efficiency. Utility Model Content

[0029] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0030] like Figure 1-4As shown, the technical solution adopted by the present invention is specifically as follows: an X-ray machine laser alignment device, comprising a base 1, a left-right moving component is arranged on the base 1, an electric telescopic rod 2 is arranged on the left-right moving component, a rotating component is installed on the telescopic end of the electric telescopic rod 2, a hollow shell 3 is arranged on the rotating component, a fine-tuning component is arranged inside the hollow shell 3, the fine-tuning component is provided with a symmetrically arranged first threaded block 4 and a second threaded block 5, an X-ray machine body 6 is arranged on the first threaded block 4, a laser emission locator 7 is arranged on the second threaded block 5, and the X-ray machine body 6 and the laser emission locator 7 are symmetrically arranged.
[0031] Its working principle is as follows: when performing X-ray detection, in order to ensure accuracy, the doctor will first carefully mark the cross mark on the patient's body part, which provides a key reference for subsequent positioning operations. Then, the laser emission locator 7 is started, and the laser beam it emits is accurately projected on the cross mark on the patient. Due to its strong directionality and high brightness, the laser beam allows the doctor to clearly identify the relative position relationship between it and the cross mark. If the position of the laser beam and the cross mark does not completely match, the doctor can easily adjust the laser emission locator 7 horizontally by moving the component left and right to ensure that it is aligned with the cross mark. In addition, the doctor can also use the electric telescopic rod 2 to accurately adjust the height of the laser emission locator 7 so that it perfectly matches the height of the detection part. When the position and height of the laser emission locator 7 are adjusted in place, the fine adjustment function of the fine adjustment component becomes particularly important. It can further optimize the position of the laser emission locator 7 to ensure that it is completely consistent with the cross mark. Subsequently, the doctor rotates the hollow shell 3 to the specified position by rotating the component. Since the X-ray machine body 6 and the laser emission locator 7 are symmetrically arranged, when the laser emission locator 7 is rotated into place, the X-ray machine body 6 will also rotate to the appropriate position accordingly. Since the X-ray machine body 6 and the laser emission locator 7 are symmetrically arranged, once the laser alignment device completes the positioning of the patient, the X-ray machine body 6 can be immediately rotated to the corresponding position without the need for additional positioning steps, which can significantly reduce the time from laser positioning to X-ray irradiation, thereby improving work efficiency.
[0032] Compared with the prior art, the advantages of the utility model are as follows:
[0033] 1. Reduce positioning time:
[0034] In the prior art, the laser emission positioner 7 and the X-ray machine body 6 may not be symmetrically arranged, so additional positioning and calibration steps may be required before X-ray irradiation, which increases the time from laser positioning to X-ray irradiation.
[0035] The symmetrical setup reduces these extra steps, significantly shortening positioning time and improving work efficiency.
[0036] For a clearer comparison with the prior art, the prior art adjustment steps are as follows: First, a laser beam is emitted using the laser emission locator 7. The doctor or operator determines the approximate position of the X-ray target area to be irradiated by observing the projection of the laser beam on the patient's body. According to the indication of the laser beam, the doctor may need to adjust the patient's body position to ensure that the patient is in the most suitable position for X-ray irradiation. After the initial positioning, the doctor may need to further adjust the angle or position of the laser emission locator 7 to ensure that the laser beam is accurately aligned with the target area. This may require repeated adjustment and confirmation of the position of the laser beam. After the laser positioning is completed, the X-ray machine needs to be moved to the position indicated by the laser beam. This may involve moving the X-ray machine, adjusting its height, angle, and rotation, etc., to ensure that the X-ray machine can accurately align with the target area. In addition, internal calibration of the X-ray machine may also be required to ensure the accuracy and consistency of the X-ray beam.
[0037] 2. Maintain positioning accuracy:
[0038] In the prior art, the positioning between the laser emission positioner 7 and the X-ray machine body 6 may not be completely consistent, which may lead to positioning errors.
[0039] The symmetrical setting ensures the precise correspondence between the laser emission positioner 7 and the X-ray machine body 6, thereby reducing the potential errors introduced by the movement or repositioning of the equipment and improving the accuracy of positioning.
[0040] 3. Improve the flexibility of equipment use:
[0041] In the prior art, the laser emission positioner 7 and the X-ray machine body 6 may not serve as backup for each other, so once one of the devices fails, the entire workflow may be affected.
[0042] The symmetrical configuration allows the laser emission positioner 7 and the X-ray machine body 6 to be used interchangeably, thereby improving the availability and flexibility of the equipment and reducing downtime caused by equipment failure.
[0043] 4. Optimize space layout:
[0044] In the prior art, the laser emission positioner 7 and the X-ray machine body 6 may need to occupy different working spaces respectively, resulting in a large overall space requirement.
[0045] The symmetrical configuration enables two devices to share the same working space, optimizing the layout of medical equipment, reducing the overall space required, and making medical processes more compact and efficient.
[0046] 5. Enhanced Security:
[0047] In the prior art, frequent movement and repositioning of equipment may increase risks during operation, such as equipment collision or misoperation.
[0048] The symmetrical setup reduces movement and repositioning of equipment, reducing these risks and thus enhancing the safety of medical procedures.
[0049] 6. Simplify the operation process:
[0050] In the prior art, the operation process of the laser emission locator 7 and the X-ray machine body 6 may be relatively complicated, requiring the operator to have a high level of skills.
[0051] The symmetrical setup simplifies the process, reduces reliance on operator skills, reduces the potential for errors and confusion, and makes the process simpler and more intuitive.
[0052] In summary, by comparing with the prior art, the symmetrically arranged laser alignment device and the X-ray machine body 6 have obvious advantages in reducing positioning time, maintaining positioning accuracy, improving equipment flexibility, optimizing spatial layout, enhancing safety and simplifying operation procedures. These advantages jointly improve the overall performance and efficiency of medical equipment and provide a more convenient, safe and efficient solution for medical work.

[0054] The base 1 is provided with a first slide groove 11 , and a third threaded block 10 is arranged inside the first slide groove 11 , so that the entire left-right moving assembly can work.
[0055] like Figure 4 As shown, the fine-tuning assembly includes a second motor 12 arranged on the hollow shell 3, and a second threaded rod 13 is installed at the output end of the second motor 12. The end of the second threaded rod 13 away from the second motor 12 passes through the hollow shell 3, and the second threaded rod 13 is provided with opposite threads, and the opposite threads are sleeved with a first thread block 4 and a second thread block 5.
[0056] The second motor 12 drives the second threaded rod 13 to drive the first threaded block 4 and the second threaded block 5 to respectively drive the X-ray machine body 6 and the laser alignment device to perform relative movement or opposite movement, so that the moving distances therebetween are the same, thereby achieving accurate positioning.
[0057] The hollow shell 3 is provided with a second slide groove 14 , and the first thread block 4 and the second thread block 5 are arranged inside the second slide groove 14 so that the first thread block 4 and the second thread block 5 can move inside the second slide groove 14 .
[0058] At the same time, a limiting block is arranged at the center of the second slide groove 14, and the limiting block can be used for positioning.
[0059] The rotating assembly includes a third motor arranged on the electric telescopic rod 2, the output end of the third motor is connected to the hollow shell 3, and the hollow shell 3 is driven to rotate by the third motor.
[0060] The third motor is connected to the center of the hollow shell 3 so that the position can be positioned and stabilized during rotation.
[0061] The laser emission locator 7 comprises:
[0062] 1. A laser transmitter, used to emit a laser beam;
[0063] 2. A laser guide, used to reflect the laser beam to the position to be photographed;
[0064] 3. A laser receiver, used to receive the reflected laser beam;
[0065] 4. A controller, used for receiving laser beam information;
[0066] Working principle:
[0067] When in use, start the laser transmitter to generate a laser beam, guide the laser beam to the part to be photographed through the laser guide, the part to be photographed emits a laser beam to be received by the laser receiver, and transmits the received laser beam information to the controller, calculates the position information of the part to be photographed, and then achieves precise focus and positioning through the left and right moving components, the electric telescopic rod 2 and the fine-tuning component.
[0068] The working principle of this utility model is as follows: when performing X-ray detection, in order to ensure accuracy, the doctor will first carefully mark the cross mark on the patient's body part, which provides a key reference for the subsequent positioning operation. Then, the laser emission locator 7 is started, and the laser beam it emits is accurately projected on the cross mark on the patient. Due to its strong directionality and high brightness, the laser beam allows the doctor to clearly identify the relative position relationship between it and the cross mark. If the position of the laser beam and the cross mark does not completely match, the doctor can easily adjust the laser emission locator 7 horizontally by moving the component left and right to ensure that it is aligned with the cross mark. In addition, the doctor can also use the electric telescopic rod 2 to accurately adjust the height of the laser emission locator 7 so that it perfectly matches the height of the detection part. When the position and height of the laser emission locator 7 are adjusted in place, the fine adjustment function of the fine adjustment component becomes particularly important. It can further optimize the position of the laser emission locator 7 to ensure that it is completely consistent with the cross mark. Subsequently, the doctor rotates the hollow shell 3 to the specified position by rotating the component. Since the X-ray machine body 6 and the laser emission locator 7 are symmetrically arranged, when the laser emission locator 7 is rotated into place, the X-ray machine body 6 will also rotate to the appropriate position accordingly. Since the X-ray machine body 6 and the laser emission locator 7 are symmetrically arranged, once the laser alignment device completes the positioning of the patient, the X-ray machine body 6 can be immediately rotated to the corresponding position without the need for additional positioning steps, which can significantly reduce the time from laser positioning to X-ray irradiation, thereby improving work efficiency.
