Flexible electronic nephroscope with bendable tail end

Abstract

The invention relates to the technical field of electronic nephroscopes, and discloses a flexible electronic nephroscope with a bendable tail end, the flexible electronic nephroscope comprises a nephroscope body, a light source and a camera shooting integrated system, the light source and the camera shooting integrated system are matched with the nephroscope body, the nephroscope body comprises a nephroscope pipe and a handle nephroscope operation part, the nephroscope pipe comprises a main hose, and the left end of the main hose is fixedly connected with a bending part protection pipe; a bending assembly is arranged in the bending part protection pipe, a control mechanism used for controlling the bending assembly is arranged in the handle operation part, the bending assembly comprises a bending snake bone, the left end and the right end of the bending snake bone are fixedly connected with a left end piece and a right end piece respectively, and a turning wheel is driven to rotate by shifting a corner knob. According to the flexible electronic nephroscope with the bendable tail end, the flexible steel wire can pull one end of the left end piece, the bent snake bone drives the nephroscope pipe to be bent, the active bending part of the nephroscope pipe is bent in the front direction and the back direction, the bending angle is 200 + / -10 degrees, bending is free of damping, the nephroscope can conveniently reach the renal pelvis and all renal calyces, and no dead angle is left for stone breaking and removing.

Description

technical field [0001] The invention relates to the technical field of electronic nephroscope, in particular to a flexible electronic nephroscope with a bendable end. Background technique [0002] With the development of science and technology, the instruments used in surgical operations have also undergone rapid changes. Improvements in surgical instruments allow doctors to perform operations better, with shorter operation times and less trauma to patients. Urinary calculi are one of the common diseases in urology and often require surgical treatment. At present, percutaneous nephrolithotomy is the standard treatment for kidney stones with a diameter greater than 2 cm, and can handle almost all kidney stones with a diameter greater than 2 cm. However, staghorn calculi (parallel calculi) are still a difficulty in percutaneous nephrolithotomy, limited by the anatomical shape of the renal collecting system, when treating staghorn calculi (parallel calculi), the existing main...

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the invention provides a bendable end with simple and reliable structure, high degree of freedom, suitable bending angle and bending radius, which can easily reach the renal pelvis and each renal calices, and remove stones without leaving any dead ends. Flexible electronic nephroscope; it solves the problem that the end-bendable combined percutaneous nephroscope in the prior art is easily damaged, and the existing electronic nephroscope has a large bending radius, and the end of the mirror body cannot make a sharp turn, which is inconvenient in complex structure The operation and field of vision in the renal calyces are not clear enough, and the observation of parallel renal calices with punctured renal calices and the technical problems of stone crushing are not good
