Abstract

The invention discloses a force feedback device and a lung puncture robot.The force feedback device is provided with a linear guide rail, a spring supporting base plate, a pressure spring, an operating lever and a fixing frame; the linear guide rail is arranged between a baffle on the top of the fixing frame and a supporting platform on the lower portion; the spring supporting base plate is fixedly arranged on the linear guide rail;the operating lever is arranged on the upper portion of the baffle and is elastically connected with the spring supporting base plate through the pressure spring. The force feedback to the operating lever is achieved by means of combination of the linear guide rail and the pressure spring; meanwhile, by means of the force feedback device, following movement of amanipulated mechanical arm can be achieved, and then the purpose of establishing the relationship between the positions of an operating end and a driven end and the force is achieved; therefore, existence of the feedback force felt by componentsin a large range is achieved, and the technical effect of improving the accuracy and real-time performance of the response is achieved.

Description

technical field [0001] The present application relates to the technical field of force feedback, in particular, to a force feedback device and a lung puncture robot. Background technique [0002] The force feedback device represents an innovation in human-computer contact and interaction technology. In the past, computer users could only interact with it through vision. Obviously, the sense of touch, as the most important perception method in many applications, has not been added. The six-degree-of-freedom force feedback device The emergence of the computer has changed all this, just as the display enables the user to see the image generated by the computer, and the speaker enables the user to hear the sound synthesized by the computer, and the force feedback device makes it possible for the user to touch and operate the virtual object generated by the computer. [0003] The force feedback devices currently used in the market have the disadvantages of small motion range and ...
