In order to realize the functions, the technical scheme adopted by the utility model is as follows: a guide wire and a push tube with a positioning function comprise a guide wire and a push tube; the seal wire includes soft head of arc, scale one, soft section core silk, dials the piece, transfers to pole and hard section core silk, soft section core silk is connected in the soft head of arc, goes out the ureter after the guide for guide ureteroscope, ureteral stent tube, hard section core silk is connected in soft section core silk, dial the piece and connect in hard section core silk, it locates to dial on the piece to transfer to the pole, the direction of dialling the piece is unanimous with the direction of the soft head of arc for the direction of the soft first arc part of sign, the location is accurate, scale one is located on the soft section core silk lateral wall, and the scope of being convenient for looks directly down seal wire or ureteral stent tube business turn over degree of depth control.

Further, the push tube comprises a tube body, a second graduated scale and a marking ring, wherein the second graduated scale is arranged on the outer side wall of the tube body, so that the inlet and outlet depth of the ureteral stent tube can be controlled under the direct vision of an endoscope, the marking ring is arranged on the tube body, the marking ring is composed of a slightly thick bump and a radiopaque metal ring, and when the ureteral stent tube is pushed in, the ureteral stent tube is sleeved outside the marking ring.

Furthermore, the guide wire main body part is made of a water-resistant and corrosion-resistant stainless steel alloy material, a hydrophilic coating is arranged on the outer side wall of the guide wire main body, and the hydrophilic coating is made of a medical sterile high polymer material with good biocompatibility and hydrophilic polarity, so that various operations in a urinary tract water environment are facilitated.

Furthermore, the arc-shaped soft head is made of elastic high polymer materials and is used for initial guiding of the ureter and the renal pelvis, and mechanical stimulation and damage to the ureter and the renal pelvis are reduced.

Further, the diameter of the guide wire is matched with the inner diameter of a ureteral stent tube commonly used in urology.

The utility model adopts the structure to obtain the following beneficial effects: the guide wire and the push tube with the positioning function are arranged through the guide wire and the guide tube, are light and portable, have simple and direct vision of the in-and-out depth, obviously shorten the judgment time of the in-and-out depth of the guide wire in the operation, are convenient to control the entering direction of the guide wire through the direction adjusting rod, are accurately positioned, and are convenient for various operations in the urinary tract water environment.
