[0045] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0046] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Although the illustrations only show components related to this utility model and are not drawn according to the actual number, shape and size of the components, the shape, quantity, positional relationship and proportion of each component can be arbitrarily changed under the premise of realizing the technical solution of this utility model, and the layout of the components may also be more complex.

[0047] Portable collimators, as advanced medical device components, play a crucial role in precisely controlling and adjusting the size and shape of the X-ray beam during X-ray imaging. This technology not only ensures the capture of high-quality X-ray images but also significantly optimizes diagnostic accuracy and efficiency. By finely adjusting the X-ray beam, the collimator effectively reduces scattered radiation, a characteristic essential for improving image clarity and contrast. This allows physicians to observe fine structures within the patient's body more clearly, providing strong support for accurate diagnosis.

[0048] However, existing portable mobile collimators also face several challenges during use. Particularly during the repeated rotation of the collimator along with the host computer's rotating components, the reliability and durability of the wiring harness become critical issues. Due to frequent rotation, the wiring harness may rub against or become stuck with other structural components of the host computer. This can lead to tension on the harness, poor interface contact, and in severe cases, even wire breakage. These problems not only affect the normal operation of the portable mobile collimator and reduce image quality but may also increase maintenance costs and impact the continuity and efficiency of medical services.

[0049] To address the above problems, this utility model provides a portable clamping device, which will now be described in detail with reference to the following embodiments and accompanying drawings.

[0050] Example 1

[0051] This embodiment provides a portable clamp limiter, as shown in the following example. Figures 1 to 6 The limiter 01 includes a limiter body 1, an adapter 2, and a communication component 3.

[0052] Specifically, refer to Figure 1The constraint limiter body 1 includes a top 011 and a bottom 012 disposed opposite to each other, and the constraint limiter body 1 includes at least one handle 10, for example Figure 1 As shown, in order to facilitate operation, a pair of handles 10 are provided on both sides of the bottom 012 of the clamping device body 1. The handles 10 are located at the bottom of the clamping device body 1. The design of the handles 10 makes it easy for users to carry, move or adjust the position of the clamping device, thus improving the convenience of operation.

[0053] Reference Figure 2 and Figure 13 In existing portable mobile clamp limiters, during use, the wiring harness in the clamp limiter 01 may become stuck and pulled against other structural components of the host computer 02 as it repeatedly rotates with the rotating parts of the host computer 02. This can lead to poor interface contact or even wire breakage, affecting the normal operation of the clamp limiter 01. Therefore, this application provides an adapter component 2 and a communication component 3 on the top 011 of the clamp limiter 01, eliminating the need for traditional external system cables. For compatibility with the adapter component 2, refer to... Figure 7 The clamp limiter 01 also includes a limiting block 5, which is located at the top 011 of the clamp limiter body 1 and is positioned opposite to the top plate 21.

[0054] like Figure 2 As shown, the adapter component 2 is located at the top 011 of the clamp limiter body 1. The adapter component 2 includes a top plate 21, which is spaced apart from the top 011 of the clamp limiter body 1. (Refer to...) Figure 8 and Figure 9 The adapter 2 also includes a stop component 23. The stop component 23 is located on the top plate 21 of the adapter 2 and protrudes towards the top 011 of the limiter body 1. The distance the stop component 23 extends from the top plate 21 is not less than the minimum distance between the limiting block 5 and the top plate 21. The stop component 23 is rotatable relative to the limiting block 5. In an optional embodiment of this embodiment, referring to... Figures 7 to 9 Two limiting blocks 5 are provided on the top 011 of the constraint body 1, opposite to the top plate 21. A stop component 23 is provided on the top plate 21, opposite to the top 011 of the constraint body 1. The geometric centers of the two limiting blocks 5 are located on the same circular circumference, and the obtuse angle θ formed by the two radii passing through the geometric centers of the two limiting blocks 5 is 300 degrees. When the constraint 01 is rotated, due to the presence of the limiting blocks 5 and the stop component 23, the constraint 01 of this invention can rotate within a range of 300°.

[0055] refer to Figure 3 , Figure 4 and Figure 13The adapter component 2 also includes a sidewall 22, with a radially outward flange 221 formed at the end of the sidewall 22 away from the top plate 21. A flange mounting seat 4 is fixedly mounted on the top 011 of the clamping device body, and the outer edge of the flange 221 is rotatably connected to the flange mounting seat 4. The top plate 21 of the adapter component 2 is formed into a circular ring structure, and the flange 221 is also formed into a circular ring structure, with the outer diameter of the flange 221 being larger than the outer diameter of the top plate 21. The flange 221 includes a plurality of limiting grooves 2211 evenly distributed along its outer edge. This allows the adapter component 2 to rotate the clamping device 01 or the host computer 02 to different angles, thereby enabling the capture of X-rays at different angles. For example, in an optional embodiment of this example, the number of limiting grooves 2211 is 8. Using the outer edge of the flange 221 as the circumference, straight lines are drawn from any point on the center line of two adjacent limiting grooves 2211 to the center of the circle, and the acute angle formed by the two straight lines is 45 degrees. (Refer to...) Figure 8 A limiting component 41 is provided on the flange mounting base 4. When the beam limiter 01 is rotated, the limiting component 41 can engage with the limiting groove 2211 when rotated to a certain angle, facilitating the capture of X-rays at different angles, thereby allowing adjustment of the X-ray irradiation direction according to the shooting requirements. This flexibility makes it easier for the operator to capture various angles of the object being photographed, thereby obtaining more comprehensive and accurate image information.

[0056] like Figure 5 and Figure 6 As shown, the communication component 3 includes a top plate PCB 31, a flange PCB 32, and a flexible spring 33.

[0057] Reference Figures 2 to 6 and Figure 13The top plate PCB 31 is fixed to the top 011 of the constraint limiter body 1 and is positioned opposite to the top plate 21 of the adapter component 2. The flange PCB 32 is positioned on the top plate 31 of the adapter component 2 and is positioned opposite to the top plate PCB 31. One end of the flexible spring 33 is fixed to the flange PCB 32, and the other end is in contact with the top plate PCB 31. The flexible spring 33 includes multiple pins. The distance between the top plate PCB 31 and the flange PCB 32 is between 3mm and 8mm, and further, the distance between the top plate PCB 31 and the flange PCB 32 is between 4mm and 6mm. Specifically, in this embodiment, the distance between the top plate PCB 31 and the flange PCB 32 is 5mm. Copper plating usually refers to laying copper material on a circuit board or other electronic equipment. Copper is widely used because of its good electrical and thermal conductivity. The top plate PCB 31 is provided with multiple sliding grooves 311, which are copper plating sliding grooves. The pins of the flexible spring 33 are in contact with the sliding grooves 311 one by one. Each sliding groove 311 leads to a wire that exits from the lower surface of the top PCB 31 and connects to the internal circuitry of the limiter 01. That is, each flexible spring 33 has a pin contact corresponding to a sliding groove 311. At this time, the pin contacts of the flexible spring 33 are in a closed contact state with the sliding grooves 311 of the top PCB 31. During the rotation of the limiter 01, the pin contacts of the flexible spring 33 remain in contact with the sliding grooves 311 of the top PCB 31, ensuring that the circuit remains closed and providing a reliable guarantee for stable signal transmission. This closed contact state is crucial for ensuring normal signal transmission.

[0058] Each pin of the flexible spring 33 is covered with a copper wire. These copper wires are led out through solder lines from the upper surface of the top PCB 31, passing through the flange PCB 32 and entering the system of the host computer 02, facilitating power supply and signal transmission with the host computer 02. Furthermore, there are no external system cables. This design not only achieves efficient transmission of electrical signals and power but also greatly simplifies the system's connection structure, avoiding the cumbersome and inconvenient nature of external system cables. This cable-free design not only makes the structure of the limiter 01 more compact and aesthetically pleasing but also improves the overall stability and reliability of the system. Simultaneously, the flexible spring 33 is connected to the host computer 02 system via copper wires. This design not only simplifies the signal transmission path but also improves the speed and efficiency of signal transmission. This efficient signal transmission method is crucial for ensuring the real-time response and stable operation of the system.

[0059] Reference Figures 2 to 6 and Figure 13The communication component 3 also includes a spring mounting bracket 34, which is fixed to the top plate 21 by adhesive and screws. The flexible spring 33 is fixed to the spring mounting bracket 34 by fixing screws. This design not only enhances the stability of the structure, but also ensures the positioning accuracy of the spring mounting bracket 34 during rotation, providing a solid foundation for the installation and operation of the flexible spring 33.

[0060] Reference Figures 1 to 9 as well as Figure 13 The host computer 02 supplies power to the limiter 01 through the communication structure 3, and the internal signals of the limiter 01 are transmitted to the host computer 02 through the communication structure 3. By setting the adapter 2 and the communication structure 3 on the limiter 01, the pin contacts of the flexible spring 33 and the sliding groove 311 are always in contact and closed during the rotation of the limiter 01, realizing the power supply and signal communication between the limiter 01 and the host computer 02. There are no external system cables, the structure is compact, and it is easy to carry.

[0061] Example 2

[0062] This embodiment also provides a portable beam limiter. The portable beam limiter 01 in this embodiment also includes a beam limiter body 1, an adapter component 2, and a communication component 3, and can achieve the same technical effects as in Embodiment 1. (Refer to...) Figure 7 The constrictor body 1 contains an openable lead leaf 15. (Refer to...) Figure 8 and Figure 9 In this embodiment, the portable clamp limiter control system also includes a gear assembly 14 and an angle encoder device 12.

[0063] Reference Figure 1 and Figure 10 The beam limiter 01 of this utility model also includes a lead blade opening and closing knob 13. The lead blade opening and closing knob 13 is set on the outer surface of the beam limiter body 1. This design not only facilitates intuitive observation and quick operation by the operator, but also ensures the stability and durability of the knob. The operator can achieve precise control of the opening and closing state of the lead blade 15 by simply rotating the lead blade opening and closing knob 13. The operator controls the opening and closing of the lead blade 15 by rotating the lead blade opening and closing knob 13. The lead blade opening and closing knob 13 includes a longitudinal lead blade opening and closing knob 131 and a transverse lead blade opening and closing knob 132. The longitudinal lead blade opening and closing knob 131 and the transverse lead blade opening and closing knob 132 control the opening and closing of the lead blade 15 in two different directions (longitudinal and transverse), respectively. This design allows the operator to easily adjust the shape and size of the radiation beam by operating the longitudinal lead blade opening and closing knob 131 and the transverse lead blade opening and closing knob 132 to match the size of the target area. To facilitate understanding of the structure of the longitudinal blade opening and closing knob 131 and the transverse blade opening and closing knob 132, the longitudinal blade opening and closing knob 131 will be described in detail as an example.

[0064] like Figure 10 and Figure 11 As shown, the longitudinal lead blade opening and closing knob 131 includes a connecting rod 1311 and a knob cover 1312. The connecting rod 1311 is connected to the knob cover 1312. One end of the connecting rod 1311 is disposed on the inner surface of the clamping device body 1, and the other end extends outward from the surface of the clamping device body 1 and is connected to the knob cover 1312. The operator rotates the longitudinal lead blade opening and closing knob 131 by rotating the knob cover 1312.

[0065] Reference Figure 2 , Figure 10 and Figure 13 An angle encoder device 12 is disposed within the clamp limiter body 1. The angle encoder device 12 is used to detect the opening and closing information of the lead blade 15 and transmit the opening and closing information of the lead blade 15 to the host computer 02. The angle encoder device 12 uses the clamp limiter 01 (see reference). Figure 1 The internal power supply allows for use in different locations without an external power connection, thus improving the system's flexibility and applicability. The angle encoder device 12 is provided in a one-to-one correspondence with the longitudinal lead blade opening / closing knob 131 and the transverse lead blade opening / closing knob 132. Specifically, in this embodiment, referring to... Figure 10 There are two angle encoder devices 12. One angle encoder device 12 is adjacent to the longitudinal blade opening / closing knob 131 and is used to detect and transmit the longitudinal opening / closing information of the blades. The other angle encoder device 12 is adjacent to the transverse blade opening / closing knob 132 and is used to detect and transmit the transverse opening / closing information of the blades. (Refer to...) Figure 11 The angle encoder 12 includes an encoder gear 121.

[0066] like Figure 10 and Figure 11 As shown, gear assembly 14 is disposed inside the limiter body 1 and connected to lead blade 15 to adjust the opening and closing size of lead blade 15. Gear assembly 14 is meshed with encoder gear 121, and gear assembly 14 is correspondingly provided with longitudinal lead blade opening and closing knob 131 and transverse lead blade opening and closing knob 132. That is, each longitudinal lead blade opening and closing knob 131 and transverse lead blade opening and closing knob 132 corresponds to a specific gear assembly 14. Gear assembly 14 includes sector gear 141 and knob gear 142. Figure 12 As shown, the sector gear 141 is connected to the lead blade 15 to drive the encoder gear 121 to rotate and the lead blade 15 to move. Figure 11 As shown, the knob gear 142 is connected to the connecting rod 1311 of the blade opening and closing knob 13. When the operator rotates the blade opening and closing knob 13, the connecting rod 1311 of the blade opening and closing knob 13 will drive the knob gear to rotate.

[0067] like Figure 1 , Figure 2 andFigure 13 As shown, the beam limiter 01 also includes a Time-of-Flight (TOF) module 11, which is housed inside the beam limiter body 1. The TOF module 11 is small in size and highly integrated. The ranging principle of the TOF module 11 involves continuously sending light pulses to the target, then using a sensor to receive the light returning from the object. The distance to the target is obtained by detecting the round-trip time of the light pulses. The TOF module 11 measures the distance from the target object to the beam limiter body 1 and transmits the distance information to the host computer 02 for further processing and analysis. The TOF module 11 can achieve full-range intelligent ranging (0.3m to 2.5m). The TOF module 11 uses the power supply inside the beam limiter 01, allowing it to be used in different locations without an external power supply, thus improving the system's flexibility and applicability.

[0068] Reference Figure 2 and Figures 10 to 13 The following is a brief description of the working process and principle of the angle encoder device 12. The knob gear 142 and the sector gear 141 are connected by a precise meshing design. When the lead blade opening / closing knob 13 rotates a certain angle, the knob gear 142 drives the sector gear 141 to rotate, and the sector gear 141 further drives the encoder gear 121 to rotate a certain angle. The angle encoder device 12 converts angle information into electrical signals and transmits these signals to the host computer 02. The host computer 02 has a built-in algorithm and program that can process the electrical signals. Through algorithm calculation, the host computer 02 can obtain the accurate position of the lead blade 15 and feeds back the accurate position of the lead blade 15 to the control terminal. The control terminal then fine-tunes or confirms the opening / closing state of the lead blade 15 based on the accurate position information fed back by the host computer 02, thereby achieving precise control of the X-ray irradiation range and reducing the risk of excessive radiation to patients.

[0069] Reference Figure 1 , Figures 2 to 13 and Figures 1 to 13 In this embodiment, by setting an angle encoder device 12 and a gear assembly 14 on the collimator 01, the position information of the lead leaf 15 can be fed back in real time, enabling the operator to accurately control the X-ray irradiation range and reduce the risk of excessive radiation to patients. Simultaneously, a TOF module device 11 is set inside the collimator 01 to measure the distance from the target object to the collimator body 1 and transmit the distance information to the host computer 02 for further processing and analysis. It can display and collect the distance information of the detected object in real time, achieving full-range intelligent ranging (0.3m to 2.5m).

[0070] Reference ​Furthermore, the portable collimator of this embodiment not only achieves power supply and signal communication between the collimator 01 and the host computer 02 by setting the adapter component 2 and the communication component 3 on the collimator 01, ensuring that the pin contacts of the flexible spring 33 and the sliding groove 311 are always in a closed contact state during the rotation of the collimator 01, without external system cables, but also has a compact structure and is easy to carry. Moreover, it achieves precise control of the X-ray irradiation range, reducing the risk of excessive radiation to patients.
