Ureteral stent puller

Abstract

The invention relates to a ureteral stent puller. The ureteral stent puller is provided with a rubber pipe and a solid wire, wherein the rubber pipe is 30cm in length and has a diameter of NO.Fr6; the tail end of the rubber pipe is connected with a water injection pipe; the head end of the rubber pipe is provided with a first small hole and second small hole; the first small hole is positioned in the end part of the rubber pipe; the second small hole is positioned in the side wall of the rubber pipe, and the distance between the second small hole and the first small hole is 1cm; the solid wire enters into the rubber pipe through the second small hole and passes through the second small hole; the solid wire is a nylon wire. The ureteral stent puller has the advantages that the rubber pipe is adopted and the solid wire is an external member; compared with a cystoscope pulling method, a cystoscope is not needed, anesthesia is not needed, and the whole price of the external member is low; due to non-sticky property and good flexibility of the solid wire, the solid wire is in a natural state in a surgery process, so that a ureteral stent can be pulled out conveniently.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a ureteral stent tube puller. Background technique [0002] Hydronephrosis is a common urinary system disease. The most common cause is that the ureteropelvic junction is too narrow, which leads to hydronephrosis and affects kidney function. Surgery is the main method for treating ureteropelvic junction stenosis. By removing the stenosis of the ureter, Re-anastomize the non-stenotic ureter with the renal pelvis to restore the patency of the ureter. During the operation, it is generally necessary to insert a double "J" tube into the ureter (this tube is a flexible tube with both ends curled in a natural state, similar to the letter "J"), and its main function is to prevent anastomotic leakage and anastomosis The mouth is narrow, and the double "J" tube indwelling in the ureter needs to be removed about one month after the operation. The traditional way of taking the tube is to e...

Problems solved by technology

The disadvantages of this method are: 1. Anesthesia is required; 2. The cost is high; 3. The operation is difficult and the technical requirements are high

[0003] In summary, there is an urgent need for a ureteral stent puller that is simple to operate, does not require anesthesia, and is low in cost. There is no report on a ureteral stent puller that can achieve the above functions
