Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments of the specification.
[0030] Such as figure 1 As shown, in the embodiment of the present invention, the double J tube puller in the female body mainly includes the following components:
[0031] 1. The mesh basket is similar to the "stone basket" for taking stones. It can be shrunk into a long strip. When shrunk, the total length is 5cm, and when it is opened, the shortest is about 3cm. It then sinks into the guide wire, and the guide wire is placed in a thin tube with a diameter of about 1.5mm. The front part of the guide wire is connected to a mesh basket wire and connected to the operating rod at the end, which can be adjusted through the handle at the end.
[0032] 2. The rubber tip is conical and located at the front end of the mesh basket, which can prevent tissue damage after entering the bladder; and when the whole is closed, the rubber tip mat...

Description
technical field [0001] The invention belongs to the field of clinical medicine and medical equipment, and relates to a puller suitable for pulling out double J tubes in women. Background technique [0002] Double J tube, also known as ureteral stent tube, double pigtail catheter or D-J tube, is widely used in urological surgery. It is suitable for the treatment of upper urinary tract operations such as kidney stones, ureteral stones, hydronephrosis, kidney transplantation, benign tumors of the kidney and ureter, as well as lithotripsy and dilation of ureteral strictures. After it is implanted in the ureter, it can play an important role in draining urine and preventing ureteral stricture and adhesion blockage. All indwelling double J tubes need to be removed after a certain period of time. At present, cystoscopy is the main method for removing double J tubes. equipment, and also the physicians and nurses required to operate it. In addition, for patients, the cost of extub...
