[0017] Furthermore, a hand-holding slot is provided on the protective cover.

[0018] Compared with the prior art, the utility model provides a disposable urinary hydrophilic guide wire, which has the following beneficial effects:

[0019] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model can facilitate the delivery of the guide wire body into the ureter through the traction part provided in the device. The straightening part provided in the device can make the guide wire body always in a straight state during the delivery process, reducing the possibility of bending of the guide wire and improving the comfort during delivery. The first curved surface and the second curved surface can reduce the friction between the guide wire and the ureter during the delivery process, thereby further improving the comfort during delivery.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1:

[0026] Reference Figure 1-Figure 3 , a disposable urinary hydrophilic guidewire, comprising:

[0027] Guidewire body 401;

[0028] The sheath tube 4 is connected to the guide wire body 401;

[0029] The straightening portion 2 is fixedly connected to the sheath tube 4;

[0030] The traction part 201 is fixedly connected to the straightening part 2;

[0031] The positioning joint 5 is fixedly connected to the sheath tube 4 , and the positioning joint 5 and the guide wire body 401 are fixedly connected.

[0032] The traction portion 201 defines a first arc surface 2011 .

[0033] The straightening portion 2 and the guide wire body 401 are fixedly connected.

[0034] The straightening portion 2 is provided with a second arc surface 202 , and the traction portion 201 is located above the second arc surface 202 .

[0035] The sheath tube 4 is connected with clips 3 , and multiple groups of clips 3 are evenly connected to the sheath tube 4 .

[0036] The positioning joint 5 is provided with a positioning groove 501 .

[0037] Reference Figure 1-Figure 3 When in use, the staff removes the clip 3 connected to the sheath tube 4, straightens the sheath tube 4, and then holds the straightening part 2 and slowly inserts the traction part 201 into the ureter. After the traction part 201 and the straightening part 2 are inserted into the ureter, the staff holds the positioning joint 5 and slowly inserts the guide wire body 401, and after it is inserted for a distance, it reaches the surgical position.

[0038] It should be noted that, by providing the second arc-shaped surface 202 on the straightening portion 2, the straightening portion 2 can be easily slid in the ureter, thereby reducing the friction between the straightening portion 2 and the ureter, alleviating the pain of the patient and improving the comfort.

[0039] It should also be noted that the first curved surface 2011 provided on the traction part 201 can facilitate the forward pushing of the traction part 201. At the same time, the traction part 201 is a nickel-titanium rod with a certain strength, which can effectively solve the problem in the prior art that the guide wire body 401 is easily blocked and bent by stones during insertion.

[0040] The traction part 201 provided in the device can facilitate the delivery of the guide wire body 401 into the ureter, and the straightening part 2 provided in the device can keep the guide wire body 401 in a straight state during the delivery process, thereby reducing the possibility of guide wire bending and improving the comfort during delivery.

[0041] The traction part 201 is connected with a sheath 1 , and the sheath 1 and the straightening part 2 abut against each other.

[0042] Reference Figure 1 The sheath 1 connected to the traction part 201 can provide a good protective effect on the traction part 201, thereby reducing damage to the traction part 201 and ensuring the subsequent normal use of the traction part 201.

[0043] A hand holding slot 101 is formed on the protective cover 1 .

[0044] Reference Figure 1 Through the hand-holding slot 101 provided on the sheath 1, when used by medical staff, it is more convenient for the staff to hold the sheath 1 with their hands, and then the sheath 1 can be quickly pulled out.

[0045] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
