Abstract

The invention provides a flexible ureteroscope pushing mechanism and a surgical instrument adopting the flexible ureteroscope pushing mechanism. The flexible ureteroscope pushing mechanism comprises afirst pushing assembly, a supporting base, a second pushing assembly and a sliding base, wherein the first pushing assembly comprises a first unthreaded rod group, a first screw rod and a second screw rod, a first end of the first unthreaded rod group is connected with a first unthreaded rod support, and a second end of the first unthreaded rod group is connected with a second unthreaded rod support; a first end of the first screw rod is connected with the first unthreaded rod support, and a second end of the first screw rod is connected with a third unthreaded rod support. The first screw rod is driven by a motor; a first end of the second screw rod is connected with the third unthreaded rod support, and a second end of the second screw rod is connected with the second unthreaded rod support; the first unthreaded rod group and the first screw rod are in embedded connection with the supporting base; the second pushing assembly is connected with a robot installation base; the sliding base is connected with the first pushing assembly and the second pushing assembly. By means of the flexible ureteroscope pushing mechanism, active and passive pushing of a flexible ureteroscope is achieved, the calculus removal time is effectively shortened, and the surgical efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of flexible ureteroscope surgical instruments, in particular to a pushing mechanism of flexible ureteroscope and a surgical instrument using the same. Background technique [0002] As a kind of natural orifice endoscopic surgery, flexible ureteroscopy has developed rapidly in the past ten years. Flexible ureteroscopy is a kind of intrarenal interventional diagnosis and treatment operation carried out through the urethra-bladder-ureter-kidney with a slender flexible ureteroscope, together with various auxiliary tools, such as optical fiber, stone basket, etc., to treat kidney stones and ureteral stones Oriented diagnosis and treatment of renal diseases. Compared with traditional open surgery and percutaneous nephroscopic surgery, flexible ureteroscopy has a series of advantages such as less bleeding, high efficiency, low incidence of complications, and short hospital stay. At present, this technology has bee...
