越南采购需求：手术室设备，包括手术灯、手术台和医用吊塔

I'm looking for an operating table with specific requirements. The minimum height should be 635 mm, with a max height of 1090 mm. It needs to meet water resistance standard IP-X4. Dimensions for the tabletop are 495–540 mm in width and 2030–2150 mm in length, with a max load capacity exceeding 250 kg and a total weight greater than 360 kg. The table must allow for various positions and movements, including significant angles for Trendelenburg positions, head-up and head-down adjustments, and lateral tilts. The back, head, and leg sections must have specific upward/downward angles for optimal positioning. Height reset functions are essential for all specified sections.
