Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a CyberKnife five-dimensional treatment bed extension device. Background Art

[0002] At present, due to the high price of the original CyberKnife six-dimensional treatment bed, general treatment centers will choose domestic carbon fiber five-dimensional treatment beds as replacements.

[0003] However, the 5D treatment couch has a limited range of motion. For patients with pelvic tumors, if the target volume spans the thoracoabdominal or abdominopelvic regions, accurate tumor tracking requires the tumor center of mass to be positioned within the registration center. However, the couch's limited head-to-head movement makes it impossible to adjust the position using the bed's movement mode. Position deviations exceeding the threshold ultimately prevent the treatment plan from being executed. Furthermore, the 5D treatment couch is susceptible to deformation. Made of carbon fiber, the 5D treatment couch has low rigidity and is prone to deformation under high forces. When forward movement of the couch is limited, the patient's position fixation device is typically pushed forward head-to-head to achieve positional image registration. However, the headside of the couch lacks support. Excessive head-to-head movement of the 5D couch can cause the couch to sink and deform due to gravity, compromising tracking accuracy and increasing treatment risk.

[0004] Therefore, how to provide a CyberKnife five-dimensional treatment bed extension device has become a technical problem that urgently needs to be solved in this field. Utility Model Content

The operator can adjust the length of the extension main plate 1 that slides into the connecting assembly 2 based on the actual required movement distance. This allows for precise tumor tracking through the extension main plate 1, ensuring that positioning deviations are within a threshold and that the treatment plan can be executed.

[0034] Extension board 1 is rectangular in design and matches the five-dimensional treatment bed body, making it easy to connect and operate. The dimensions of the extension board 1 are 800mm long and 600mm wide.

[0035] During use, the operator first fixes the connecting component 2 on the five-dimensional treatment bed, and then fixes the extension main board 1 on the connecting component 2, thereby connecting the extension main board 1 to the five-dimensional treatment bed. The operator can adjust the connection length between the extension main board 1 and the connecting component 2 according to actual needs to adjust the length of the extension main board 1, which is suitable for radiotherapy of different parts and target areas of different lengths.

[0036] Then, the support legs 3 provide support to the extension main board 1, so that the patient can lie stably on the extension main board 1, thereby increasing the movement range of the five-dimensional treatment bed through the extension main board 1 and providing support for the five-dimensional treatment bed.

[0037] The present invention connects the first end of the connecting component 2 to the extension main board 1 by sliding, and the second end of the connecting component 2 is connected to the five-dimensional treatment bed; the support legs 3 are arranged at the bottom of the extension main board 1.

When not in use, the support leg 3 is accommodated in the installation groove 12, which facilitates the storage of the extension main board 1 and ensures the supporting effect on the extension main board 1. It can also improve the stability of the end area where the extension main board 1 is connected to the five-dimensional treatment bed, and avoid tracking uncertainty and error caused by deformation of the five-dimensional treatment bed.
