Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a multi-angle adjustable operating table. Background Art

[0002] The operating table, also called the operating table, is a necessary tool for doctors during surgery. It is the most important tool for placing patients and providing a more convenient operating environment for doctors. Every support surface of a general operating table, including the advanced integrated operating table on the market, is basically flat. When performing surgery, doctors need to place the surgical sheet in front of their eyes for easy observation, and place the surgical instruments directly above the bed through a separately set instrument placement bracket for easy access.

[0003] At present, the structure of the bed frame of an operating table is usually relatively fixed. This brings inconvenience to medical staff in performing surgical treatment on patients. Moreover, it also brings inconvenience to patients receiving surgical treatment. For example: when performing surgical treatment on a patient lying on an operating table including the current bed frame, medical staff usually adopt different postures, techniques, or even constantly move in order to accurately and conveniently perform surgical treatment on the patient. Or, during the surgical treatment, in order to cooperate with medical staff, the patient usually maintains an extremely uncomfortable posture, or even constantly changes posture. Obviously, the current operating table frame is extremely inconvenient to use, and thus cannot fully meet the needs of users. Summary of the invention
