Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments of the specification.

[0029] Such as figure 1 As shown, in the embodiment of the present invention, the double J tube extractor in the male body mainly includes the following components:

[0030] 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 (the front part of the inner tube), with a diameter of about 1.5mm. Handle adjustment.

[0031] 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 matches the head of the forceps, which is convenient for insertion into the urethra.

[0032] 3. The circular baf...

Abstract

The invention discloses a remover for pulling a double-J catheter out of a male body. The remover comprises a meshed basket, openable forceps, an outer silicon rubber hose, an inner silicon rubber hose, a bendable elastic guide wire, operating handles and a tail-end operating rod. The forceps are mounted at the front end of the outer hose and in linkage with the operating handles, the inner hose is embedded in the outer hose, the rear section of the inner hose is exposed outside, the meshed basket is arranged at the front end of the inner hose, and the tail-end operating rod is plugged to the tail end of the inner hose. The bendable elastic guide wire is arranged in the inner hose, one end of the bendable elastic guide wire is connected with a guide wire of the meshed basket, and the other end of the bendable elastic guide wire is connected with the tail-end operating rod. The remover for pulling the double-J catheter out of the male body has the advantages of structural ingenuity, convenience in operation and easiness in popularization and utilization.

Description

technical field [0001] The invention belongs to the field of clinical medicine and medical devices, and relates to a puller suitable for pulling out double J tubes in males. 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.
