The invention provides a steel wire driven bearing arc-shaped guide rail. The steel wire driven bearing arc-shaped guide rail comprises a guide rail, a sliding block and driving steel wires, wherein the guide rail comprises two guide plates which are arranged in parallel, the guide rail is bent in an arc shape with a preset radius, the circle center of the guide rail is a fixed point, a plurality of arc motion bearings are arranged at the two ends of the sliding block, the two ends of the sliding block are arranged between the two guide plates in a sliding mode through the arc motion bearings, limiting mechanisms are arranged between the sliding block and the guide plates, and the driving steel wires comprise the first driving steel wire and the second driving steel wire, and the first driving steel wire and the second driving steel wire are connected to the two sides of the sliding block through guide wheel assemblies correspondingly. The arc-shaped guide rail is high in adjusting precision, friction resistance among structures is small, the high-precision movement requirement of a surgical robot can be met, a balance weight mechanism is arranged and is not affected by gravity, the sliding block does not deviate in movement, and operation safety is high.
Description
technical field [0001] The invention relates to the technical field of motion guide rails, in particular to a steel wire driven bearing arc guide rail. Background technique [0002] Minimally invasive surgery is generally also called interventional surgery. It cuts several small incisions on the body surface (or relies on the natural official cavity of the human body), and with the help of the image guidance of the visual display system, inserts surgical instruments through the incisions on the body surface. The operation completed by entering the body for treatment or diagnosis. Minimally invasive surgical technology has made most surgical operations bid farewell to the open surgical mode. The application of robot technology to medical surgery has become more and more popular. The stability of robots in operation It has significant advantages in terms of speed, speed and accuracy. Integrating robotics into surgical operations can improve the operating environment for doctor...
