Problems solved by technology

When the working distance is long, the nesting of multi-layer casing can effectively reduce the reduction of the working distance, but it will cause the problem of thicker outer diameter and complex processing
These problems limit the further development of robot-assisted minimally invasive surgery technology

Abstract

The disclosure provides a robot operated flexible ureteroscope anti-bending mechanism comprising a sliding sleeve, a sliding sleeve fixing member, a polished rod, a distance measuring substrate, a distance measuring shaft, a distance measuring wheel, a first belt wheel, a linkage device and a clamping device; the sliding sleeve fixing member is nested on the sliding sleeve; the polished rod is nested in one end of the sliding sleeve, the polished rod is slidingly connected with the sliding sleeve, the distance measuring substrate is connected with the polished rod, the distance measuring shaftis connected with the distance measuring substrate, the distance measuring wheel is arranged on the distance measuring shaft in a sleeving manner and is connected with the distance measuring substrate, the first belt wheel is arranged on the distance measuring shaft in a sleeving manner and is connected with the distance measuring substrate, the linkage device is connected with the distance measuring wheel and the sliding sleeve, and the clamping device is connected with the first belt wheel via a synchronous belt. Via the mechanism disclosed in the disclosure, a flexible ureteroscope can beprevented from being bent during push processes, and the mechanism can be combined with a robot system; the mechanism is high in precision, stable in motion and high in safety and reliability.

Description

Technical field [0001] The present disclosure relates to the field of soft mirror anti-bending structures, and in particular to a robot-operated ureter soft mirror anti-bending mechanism. Background technique [0002] Flexible ureteroscopy is a natural cavity operation, which is characterized by using a flexible ureteroscope to go through the urethra-bladder-ureter-kidney to perform related operations in the kidney, such as the use of laser for kidney stone treatment and the use of stone baskets for stone removal Wait. Compared with percutaneous nephroscopy and open kidney surgery, flexible ureteroscopy has the advantages of less bleeding, less trauma, shorter hospital stay, and faster postoperative recovery. It has been more and more widely used in clinical surgery. With the development of science and technology, flexible ureteroscopy has been widely carried out at home and abroad in recent years. However, due to the slender, flexible, and non-linear characteristics of the fle...
