Abstract
The invention provides a synchronous hydraulic system of a surgical bed. The synchronous hydraulic system comprises an oil pump system, a first hydraulic cylinder, a second hydraulic cylinder and a third hydraulic cylinder; the oil pump system, a second two-position three-way valve, a second hydraulic-control check valve, a first throttle valve, the first hydraulic cylinder, a first two-position two-way valve, a first hydraulic-control check valve and a first two-position three-way valve are sequentially and serially connected with one another; the oil pump system, the second two-way three-position valve, the second hydraulic-control check valve, a second throttle valve, the second hydraulic cylinder, the first two-position two-way valve, a first hydraulic-control check valve and the first two-position three-way valve are sequentially and serially connected with one another; the oil pump system, a fourth two-position three-way valve, a fourth hydraulic-control check valve, a third throttle valve, the third hydraulic cylinder, a third two-position two-way valve, a third hydraulic-control check valve and a third two-position three-way valve are sequentially and serially connected with one another. The synchronous hydraulic system has the advantages that the synchronous hydraulic system is simple in operation, a back plate and a hip plate can synchronously rotate in the same directions or in opposite directions by the aid of the hydraulic system, so that a complicated surgical position of a patient can be reached by the aid of single action; the hydraulic-control check valves are used with the two-position three-way valves, so that the stability and the reliability of the hydraulic system can be guaranteed.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a hydraulic system for an operating bed. Background technique [0002] As one of the basic medical device products, the operating bed occupies a very important position in medical device products such as orthopedics, flukes, and surgery. The operating table is not only an essential tool for doctors during surgery, but also an important tool that patients often use during postoperative recovery. With the continuous advancement of medical technology, the types and functions of operating beds are becoming more and more abundant. From the most basic lifting function, extending to local lifting, rotation, suspension, tilting and other functions, there can also be more combined functions, such as sliding when needed, fixing when not needed; lifting the legs when needed When you don't need it, you can put the legs on the same level, and combine different functions according to differe...
