The invention discloses an endoscope zoom adjustment driving device and method and an endoscope. According to the scheme, the endoscope zoom adjustment driving device comprises an input module, a control module and a movement module, wherein the input module is arranged on an operation handle of the endoscope; the input module is in data connection with the control module, the control module is in control connection with the movement module, and the movement module is in driving connection with a zoom optical module in the endoscope; the control module is used for automatically controlling the movement module to drive the zoom optical module in the endoscope to perform zoom movement according to an input signal of the input module, and acquiring the action state of the movement module and / or the movement state of the zoom optical module to form limiting control. According to the endoscope zoom adjustment scheme provided by the invention, the reliability and efficiency of the whole endoscope zoom adjustment can be effectively improved.
Description
technical field [0001] The present invention relates to endoscopic technology. In particular, the invention relates to an endoscope zoom adjustment driving device, an operation method and the endoscope. Background technique [0002] In recent years, endoscopes have been widely used in the field of medical diagnosis. During endoscopic diagnosis, it is often necessary to insert the endoscope into the body cavity in order to see the problems in the patient's lesion area more clearly. To obtain a magnified or wide-angle image of the inspected part, a zoom lens is usually provided on the lens unit provided at the front end of the endoscope insertion part, and the observer realizes the zoom function by moving the zoom lens in the direction of the imaging optical axis. The zoom lens is generally held by a zoom lens frame, and the zoom lens advances and retreats in the direction of the optical axis as the zoom lens frame moves in the direction of the optical axis. In such an endo...
