Embodiment

[0034] A method for inserting a flexible ureteroscope sheath, comprising the following steps:

[0035] (1) Insert the D-J tube into the ureter and leave it in place for 2 weeks to pre-dilate the ureter;

[0036] (2) Insert the rigid ureteroscope from the urethral opening, pass through the urethra and bladder in sequence, and then direct the imaging probe of the rigid ureteroscope toward the ureter to provide visibility for the removal of the D-J tube and place the guide wire and safety guide wire provide visibility and orientation;

[0037] (3) Take out the DJ tube indwelling in the ureter from the urethra under the direct vision of the ureteroscope;

[0038] (4) Pass the guide wire and safety guide wire through the sheath of the rigid ureteroscope and enter the ureter, then withdraw the rigid ureteroscope, so that both the guide wire and the safety guide wire remain in the ureter, which is the end point of the rigid ureteroscope. Re-entry and initial entry of the flexible u...

Abstract

The invention discloses a method for inserting a soft sheath of a ureteroscope, belonging to the technical field of medical instruments. A guide wire is inserted before inserting the ureteroscope sheath, the guide wire guides the insertion of the ureteroscope, Ureteroscopic sheath can be easily inserted into the ureter at a predetermined position under the support, pointing and visual function ofthe ureteroscope and the guidance of the guide wire, so that the insertion process of the ureteroscopic sheath is not easy to be accidentally damaged, and the accuracy and success rate of the ureteroscopic sheath insertion are improved. In addition, the support of ureteroscope can eliminate the influence of urethral length and physiological curvature on the sheath insertion of ureteroscope.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for inserting a flexible ureteroscope sheath. Background technique [0002] At present, with the development of minimally invasive technology, flexible ureteroscopic holmium laser lithotripsy is widely used in the treatment of upper ureteral calculus and kidney stones, and the insertion of flexible ureteroscopic sheath is a key step in determining the success of the operation. [0003] At present, there are mainly two methods for inserting flexible ureteroscope sheaths: [0004] The first method is to rely on the experience and feel of the operator to insert blindly along the guide wire from the external opening of the urethra. This method has the following problems: 1. The length of the flexible ureteroscope sheath is relatively long, generally 35 cm for female patients, and more for male patients. Long, in the process of transurethral insertion, the middle par...
