Fig. 1 is a schematic structural view of the present utility model.

As shown in the figure, 1, a main rod, 2, a handle, 3 and a hook.

Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

One end of the main rod (1) is connected with a handle (2), and the other end of the main rod (1) is connected with a hook (3).

The main rod (1), the handle (2) and the hook (3) are all made of stainless steel materials.

The length of the handle (2) is 40mm, the width of the handle is 8mm, the thickness of the handle is 1.5mm, the handle is connected with the main rod (1), and the plane of the handle (2) is perpendicular to the bending direction of the hook (3).

The main rod (1) is cylindrical, the length is 150mm, the diameter tail is connected with the handle (2), the front end is slightly bent to be connected with the hook (3) to form an arc, the bending direction is perpendicular to the plane of the handle (2), and the bending angle is 160 degrees with the straight rod.

The hook (3) is connected with the front end of the main rod (1), the diameter is gradually changed from 3mm to 2mm, the bending direction is consistent with the bending direction of the main rod (1), the hook is perpendicular to the plane of the handle (2), the tail end is bent to be in a hook shape, the angle is 210 degrees, the tail end is slightly retracted inwards, the tail end is blunt, and the width of the tail end opening is 3.5mm.

Specific embodiments of the utility model:

the adult female patient performs abdomen flat slice or abdomen ultrasonic examination to ensure that the ureteral stent tube is positioned in the bladder;

The patient empties the bladder lying examination bed, removes the underpants, bends and abducts the two legs by 90-120 degrees to fully expose the perineum;

the operator wears sterile gloves, and the perineum is disinfected by iodophor and a sterile hole towel is paved;

2-4ml of obucaine gel/lidocaine gel is injected into the surface of the mucosa of the urinary tract to be anesthetized and lubricated;

2ml of oxybuprocaine gel/lidocaine gel is smeared on the front end of the metal extraction hook for 10cm to be fully lubricated;

Separating labia majora on both sides, allowing the metal extraction hook elbow to enter the bladder through the urethra upwards, rotating the metal extraction hook 180 degrees to allow the elbow to face downwards after the whole bending section enters the bladder, enabling the front end hook of the metal extraction hook elbow to be attached to the rear wall of the bladder and the tail end circle of the ureteral stent, enabling the ureteral stent pipe hook to be attached to the bladder wall in the hook and moved to the inner opening of the urethra, and finally dragging out through the urethra.

It is noted that some ureteral stents have stones attached after a long time, have resistance when being pulled out, are not pulled out by brute force, and avoid serious sequelae of ureteral avulsion (such as cystoscope extraction), such as that the ureteral stent is not hooked by multiple operations, and then the ureteral stent tube under the conventional cystoscope is extracted.

Contraindications are patients with urethral stricture, patients with ureteral bladder re-implantation, patients with acute urinary tract infection, and patients who cannot cooperate.

In the description of the present utility model, it should be noted that the term "connected" should be interpreted in a broad sense, for example, as a fixed connection, a detachable connection, or an integral connection, unless explicitly stated and defined otherwise, and that the specific meaning of the term in the present utility model may be understood in a specific sense to those skilled in the art.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
