Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a detachable modular three-dimensional angle-corrected treatment bed panel accessory. Background Art

[0002] In precision radiotherapy, accurate patient positioning is crucial. Radiotherapy positioning errors include translation and rotation angle errors. In order to ensure that the tumor target is accurately aligned with the expected position, the treatment bed needs to have the ability to perform six-dimensional corrections, including corrections for translation errors and rotation angle errors.

[0003] Currently on the market, many new and old models and high-end and low-end models are still using three-dimensional treatment beds.

[0004] On the one hand, the three-dimensional treatment beds equipped in many hospitals' older or low-end models can only be translated and adjusted in the X, Y, and Z directions, and are unable to correct angle errors, making it difficult to meet the requirements of precise radiotherapy. Directly replacing the three-dimensional treatment bed with a six-dimensional treatment bed is expensive and requires modification, limiting its widespread application.

[0005] On the other hand, some high-end radiotherapy equipment based on O-shaped frames, such as TOMO knife and nuclear magnetic resonance radiotherapy accelerator, cannot directly use the existing six-dimensional treatment bed for six-dimensional positioning correction due to their special mechanical structure.

[0006] To address the above issues, medical staff can only roughly adjust the patient's positioning angle based on their senses, but it is often difficult to adjust it in one go. This requires medical staff to repeatedly scan the patient's image and enter the shielded room to manually adjust the patient's position, which increases the positioning time and unnecessary imaging dose, increasing the burden on medical staff. So far, there has not been a solution on the market that can correct the positioning angle error and can be used with various types of existing radiotherapy equipment without requiring large-scale modification. Utility Model Content

[0007] The utility model aims to solve the deficiencies of the prior art and provides a detachable modular three-dimensional angle-corrected treatment bed panel accessory, which can provide six-dimensional correction capabilities on the basis of the existing three-dimensional treatment bed without making major modifications to the bed structure. It can be plug-and-play on existing medical equipment, and at the same time can improve the strength of the bed panel, reduce deformation, and ensure the smooth implementation of precise radiotherapy.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0009] A detachable modular three-dimensional angle-corrected treatment bed panel accessory comprises a carbon fiber bottom plate and a carbon fiber top plate. The carbon fiber bottom plate is placed on the treatment bed panel. The carbon fiber bottom plate is symmetrically provided with a plurality of bottom plate index holes front and back. The bottom plate index holes are provided with fixing buckles matching the index holes of the treatment bed panel. The fixing buckles are inserted into the corresponding bottom plate index holes and the treatment bed panel index holes. An angle correction adjustment device is provided between the four corners of the bottom of the carbon fiber top plate and the four corners of the top of the carbon fiber bottom plate. The angle correction adjustment device is connected to a control module. The control module is connected to an external data switch via a communication module. An accordion protective cover is provided around the angle correction adjustment device between the carbon fiber bottom plate and the carbon fiber top plate.

[0010] Each angle correction and adjustment device includes a mechanical execution module and a measurement module.

[0011] The mechanical execution module includes a lower support plate fixed on the top of the carbon fiber bottom plate and an upper support plate fixed on the bottom of the carbon fiber top plate. A plurality of electric telescopic rods are hinged between the lower support plate and the upper support plate through ball joint hinges, and the electric telescopic rods are connected to the control module.

[0012] The measuring module comprises a distance measuring sensor installed on the electric telescopic rod, and the distance measuring sensor is connected with the control module.

[0013] A communication module interface is provided on the side wall of the carbon fiber bottom plate, and the communication module interface is internally connected to the communication module and externally connected to a data switch.

[0014] The carbon fiber top plate is symmetrically provided with a plurality of top plate index holes at the front and rear sides.

[0015] The beneficial effects of the utility model are as follows: the utility model adopts a modular design and can be directly inserted into the index hole of the existing three-dimensional treatment bed panel. Without modifying the existing equipment, the ordinary three-dimensional treatment bed can be upgraded to a six-dimensional treatment bed, and the patient positioning angle error can be corrected instantly and accurately, thereby improving the accuracy and safety of radiotherapy.

[0027] like Figures 1 to 4 As shown, a detachable modular three-dimensional angle-corrected treatment bed panel accessory includes a carbon fiber base plate 1, a carbon fiber top plate 2, a base plate index hole 3, a fixing buckle 4, an angle correction adjustment device 5, an accordion protective cover 6, a communication module interface 7, and a top plate index hole 8.

[0028] A carbon fiber base plate 1 is placed on a treatment bed panel 9. A plurality of base plate index holes 3 are symmetrically provided on the carbon fiber base plate 1 front and back. The base plate index holes 3 are provided with fixing buckles 4 that match the index holes 10 of the treatment bed panel.

The angle correction adjustment device 5 is connected to a control module, which is connected to an external data switch through a communication module. An accordion protective cover 6 is provided around the angle correction adjustment device 5 between the carbon fiber base plate 1 and the carbon fiber top plate 2.

[0029] The model of the control module can be Omron PLC--CPM1A-V1 series.

[0030] The carbon fiber top plate 2 is provided with a plurality of top plate index holes 8 symmetrically arranged front and rear.

[0031] The carbon fiber bottom plate 1 is made of a lightweight and high-strength carbon fiber material, and has a plurality of bottom plate index holes 3 for docking with the existing treatment bed panel index holes 10 .

[0032] The carbon fiber top plate 2 is also made of carbon fiber material, connected to the carbon fiber bottom plate 1 , and has a mounting interface for the angle adjustment device 5 .

[0033] A communication module interface 7 is provided on the side wall of the carbon fiber bottom plate 1 . The communication module interface 7 is internally connected to a communication module and externally connected to a data switch.

[0034] Communication module: connected to the data switch, used to receive the positioning correction data of the radiotherapy image guidance system and transmit the angle information of the carbon fiber top plate 2 to the radiotherapy implementation system. In order to avoid radiation damage and interference to the communication module by the beam, the communication module is placed at the head and tail ends of the treatment bed.

[0035] The angle correction adjustment device 5 is installed between the carbon fiber bottom plate 1 and the carbon fiber top plate 2 to achieve precise adjustment of the pitch angle, yaw angle and roll angle of the carbon fiber top plate 2. In order to avoid radiation damage and interference of the beam to the angle adjustment device 5, the angle adjustment device 5 is placed at the head and tail ends of the treatment bed.

[0036] Each angle correction and adjustment device 5 includes a mechanical execution module and a measurement module.

[0037] The mechanical execution module includes a lower support plate 51 fixed to the top of the carbon fiber bottom plate 1 and an upper support plate 52 fixed to the bottom of the carbon fiber top plate 2. A plurality of electric telescopic rods 53 are hinged between the lower support plate 51 and the upper support plate 52 through ball joint hinges, and the electric telescopic rods 53 are connected to the control module.

[0041] The working principle and working process of the utility model are as follows:

[0042] When the patient's positioning angle needs to be corrected, the control module calculates the adjustment of the pitch angle, yaw angle and roll angle of the cover according to the positioning correction value of the radiotherapy image guidance system. These adjustments are sent to the mechanical execution module of the angle adjustment device 5. The mechanical execution module is responsible for adjusting the angle of the carbon fiber top plate 2 to ensure its rotation on the three axes of X, Y and Z. The real-time monitoring function is completed by the measurement module of the angle adjustment device 5. The measurement module monitors the angle of the carbon fiber top plate 2 in real time and transmits the angle information to the control module to ensure the accuracy of the angle correction. Finally, the angle of the carbon fiber top plate 2 will be sent to the radiotherapy implementation system through the communication module.

[0046] Improved compatibility: It can be adapted to existing three-dimensional treatment beds on the market without large-scale modifications, thus improving the compatibility of the equipment.

[0047] Cost reduction: There is no need to replace the entire treatment bed, which solves the need to upgrade the three-dimensional treatment bed to a six-dimensional treatment bed, reduces the cost of equipment upgrades, and saves money for hospitals and clinics.

[0048] Plug and Play: The unique design allows it to be directly inserted into the existing three-dimensional treatment bed panel index hole 10, achieving plug and play without the need for a complicated installation process, thus improving the ease of use and convenience of operation of the device.

[0049] Improved positioning accuracy: By correcting the angle error of the patient's positioning, the accuracy of radiotherapy positioning is improved, ensuring the accuracy of the treatment target, improving the treatment effect and patient safety.

[0050] Increased structural strength: not only can the angle be corrected, but also the strength of the treatment bed panel 9 can be increased, the deformation of the treatment bed panel 9 can be reduced, and the stability and durability of the equipment can be improved.

[0051] Adding non-coplanar radiotherapy capabilities to O-gantry-based accelerators: The angle of the treatment table can be adjusted during treatment to achieve precise application of non-coplanar radiotherapy.
