Detailed Description
The urinary catheter introducer of the present application will be described in detail with reference to the accompanying drawings.
The utility model provides a ureter director, it includes: a guide body 10 and a moving handle 30.
The introducer body 10 is made of a flexible wire for insertion into the inside of the urinary catheter 20 with its rear end exposed outside the urinary catheter 20.
The moving handle 30 includes an upper operation plate, a lower operation plate, a first bending spring 37, and a second bending spring 38; the upper operating plate is positioned above the lower operating plate; a first bending spring 37 and a second bending spring 38 are installed between the upper operation plate and the lower operation plate; a first bending spring 37 is supported at first ends of the upper and lower operation plates, and a second bending spring 38 is supported at second ends of the upper and lower operation plates; the first and second bending springs are respectively formed into a ring shape, as shown in fig. 11, and the included angle between the upper part and the lower part of the ring shape is 120-; the moving handle 30 is fitted over the outside of the urinary catheter 20 with the introducer body 10 inserted, as shown in fig. 12 and 13, so that the urinary catheter 20 with the introducer body 10 inserted is positioned between the upper and lower operation plates and passes through the first and second bending springs 37 and 38.
The upper operating plate comprises a first outer pressing plate 31, a first middle connecting plate 32 and a first inner pressing plate 33 which are connected in sequence; the first intermediate connecting plate 32 has a left end formed with a first through hole 32a and a right end formed with a second through hole 32 b.
Similarly, the lower operation plate includes a second inner pressing plate 36, a second intermediate connecting plate 35, and a second outer pressing plate 34, which are connected in this order; the left end of the second middle connecting plate forms a third through hole, and the right end forms a fourth through hole.
The upper and lower operation plates are symmetrically designed. The first and second outer pressing plates may be formed shorter than the first and second inner pressing plates.
The first bending spring 37 passes through the first through hole 32a and the third through hole, thereby being mounted on the upper and lower operation plates; the second bending spring 38 passes through the second through hole 32b and the fourth through hole, thereby being mounted on the upper and lower operation plates.
The surfaces of the first and second inner pressing plates 33, 36 facing each other are formed as arc-shaped curved surfaces.
The surfaces of the first and second inner pressing plates 33, 36 facing each other are formed with a plurality of ridges, such as teeth-like ridges, perpendicular to the extending direction of the ureter, to increase the holding force for the ureter.
When in use, the first end of the guider body is inserted into the urinary catheter, and the second end is exposed out of the urinary catheter, which is the same as the urinary catheter guider in the prior art; the moving handle is then sheathed outside the urinary catheter as shown in figures 3, 4 and 13. Moving the moving handle to the vicinity of the first end of the ureter, about 5cm from the first end of the ureter, the penis of the patient being pinched by the first hand, and the moving handle being gripped by the second hand, so that the first and second operating plates move towards each other until the ureter and the introducer body therein are merely clamped, at which point the first and second full springs are compressed, i.e. the angle between the upper and lower portions of the first and second full springs becomes smaller; the second hand moves in the direction of the first hand after gripping the moving handle, thereby inserting the urinary catheter into the urethra of the patient; when the second hand is released, the first bending spring and the second bending spring restore to the original state, the upper operating plate and the lower operating plate are also separated from the urinary catheter which is clamped between the upper operating plate and the lower operating plate, the movable handle is moved towards the second end direction of the urinary catheter, so that the distance between the movable handle and the urethral orifice is kept about 5cm, the above operation is repeated, the movable handle is gripped, and the urinary catheter outside the urethral orifice is pushed into the urethra; this is repeated until the urinary catheter is inserted to a predetermined depth. The introducer body is withdrawn from the second end of the urinary catheter and the removal handle is withdrawn from the second end of the urinary catheter (the space between the upper and lower operation plates and the loop shape of the first and second springs are formed large enough to allow the removal of the removal handle from the second end of the urinary catheter), ending the intubation procedure.
