Description

TECHNICAL FIELD

[0001] The present application relates to the field of radiotherapy, more particularly, to a treatment bed anti-winding device. BACKGROUND

[0002] Cantilever type treatment bed is very common in gamma knife and medical linear accelerator, which generally uses screw nut transmission with high precision. Since the gap between the upper bed plate connected by nut and the screw rod fixing seat is relatively large (generally more than 50mm), the patient cover on the surface of the upper bed plate (such as a drape, etc.) often has a bed sheet passing through the gap and being wound into the screw rod during treatment, which is very dangerous.

[0003] After searching, the patent document with the publication number CN115154940A provides a radiotherapy bed linear motion mechanism. The device sets the guide rail and electric screw rod in the groove type structure of the base, sets the sliding plate driven by the electric screw rod between the groove type structure and the thin plate, covers the groove type structure, the guide rail and the electric screw rod in the groove type structure with the thin plate, which can not only move the treatment bed normally through the sliding plate, but also avoid exposing the electric screw rod, providing good protection for the electric screw rod.

[0004] The above scheme needs to improve the structure of the existing equipment, which is high in cost and cannot be applied to the improvement of the existing equipment. In view of this, we propose a treatment bed anti-winding device. CONTENT OF THE INVENTION

[0015] As an optional solution of the technical scheme of the present application file, the height of the opening is greater than the height of the baffle.

[0016] As an optional solution of the technical scheme of the present application file, the width of the shielding curtain is greater than the spacing between the two baffles.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present application are:

[0019] 1) The present application can prevent the bed sheet from being rolled onto the transmission screw by setting the baffle and the shielding curtain to shield the side surface and the upper surface of the transmission screw, thereby increasing the safety of the treatment bed in use.

[0020] 2) The baffle and the shielding curtain are installed on the support plate by screws, which facilitates the improvement of the existing treatment bed and enables the baffle and the shielding curtain to be disassembled, thereby realizing the maintenance of the transmission screw.
