Embodiment 1

[0027] see Figure 1-3 , the present embodiment provides a urethral dilator for urethral stricture, including urethral probe 1, medical metal guide wire 2, fascia dilator 3, thin skin sheath 4 and urinary catheter 5, thin skin sheath 4 and corresponding type of tendons Membrane dilator 3 sockets.

[0028] In this embodiment, by setting the urethral probe 1, the hollow urethral probe 1 is inserted first when the urethra is expanded. Thin, generally can easily pass through the stenosis of the urethra, insert the medical metal guide wire 2 along the urethral probe 1, take out the urethral probe 1, and then follow the medical metal guide wire 2 to dilate the urethra with fascial dilators 3 from small to large models , and then use the thin skin sheath 4 with the fascia dilator 3 inserted on the inner wall, insert it into the posterior urethra, pull out the fascia dilator 3 and the medical metal guide wire 2, so that the passage from the urethral surgery to the bladder is establis...

Embodiment 2

[0030] see figure 1 or Figure 4 , made further improvements on the basis of Example 1: the urethral probe 1 is a hollow metal catheter, one end of the urethral probe 1 is inclined upward, and the upper side of the inclined end of the urethral probe 1 is provided with a wire outlet 6, and the wire outlet The mouth 6 enables the medical metal guide wire 2 to protrude from the wire outlet 6, and one end of the urethral probe 1 is inclined upward, and the direction can be adjusted by swinging the tail to facilitate finding the weakest part and narrow passage of the urethral atresia end.

[0031] Wherein, one end of the fascia dilator 3 communicates with the cannula, and the other end of the fascia dilator 3 is provided with a pointed expansion head, and the material of the fascia dilator 3 is a soft non-metallic material, and the fascia dilator 3 has a variety of models, the sleeve can limit the insertion position of the fascia dilator 3, and the soft texture of the fascia dilat...

Embodiment 3

[0033] see figure 2 or image 3 , on the basis of Example 1, a further improvement is made: one end of the thin leather sheath 4 is provided with an eversion portion 7, and the eversion portion 7 is sleeved on the surface of the thin leather sheath 4, and the eversion portion 7 is torn from the middle to both sides. After the catheter 5 is installed and fixed, when the thin skin sheath 4 is removed, the thin skin sheath 4 is torn along the eversion 7, and the thin skin sheath 4 can be quickly removed without the catheter 5. After fixing, the situation that the thin skin sheath 4 covers on the urinary catheter 5 cannot be taken off.

[0034] Wherein, the surface of the thin-skin sheath 4 is smooth, and the thin-skin sheath 4 is a non-metal member with high hardness and softness. Since the urethra is curved, and the narrow urethra compresses the tube wall of the thin-skin sheath 4, the pipeline will be deformed and flattened. It is difficult to insert the urinary catheter 5, ...

Abstract

The invention discloses a urethral dilator for urethral stricture and a use method of the urethral dilator. The urethral dilator for urethral stricture comprises a urethral probe, a medical metal guide wire, a fascia dilator, a thin sheath and a urinary catheter, the urethral probe is a hollow metal catheter, one end of the urethral probe is inclined upwards, a wire outlet is formed in the upper side of one inclined end of the urethral probe, the thin sheath is in sleeve connection with the fascia dilator with the corresponding model, one end of the thin sheath is provided with an outward turning portion sleeving the surface of the thin sheath, the outward turning portion is torn from the middle to two sides, and the outer diameter of the urinary catheter is smaller than the inner diameterof the thin sheath. The urethral dilator solves the problems that in practical application, the operative treatment period of urethral stricture is long, a patient has to withstand great pain withina period of time, and medical cost is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a urethral dilator for urethral stricture. Background technique [0002] Urethral stricture after hypospadias surgery is a common complication. Urethral stricture mostly occurs at the urethra of the head of the penis and the anastomosis of the proximal urethra. The main reason for the stenosis of the proximal urethral anastomosis is the poor blood supply of the formed urethra. The anastomosis is not anastomotic For other reasons, about 1 month after hypospadias is the most severe period of scarring, which can cause transient urethral stricture, and in severe cases, urethral diverticulum may develop. Urethral diverticulum often has accumulation of urine scale and stones, which is easy to cause urinary tract infection. For those with obvious urethral stricture, urethral dilatation can be used for the early stricture within 3 months after operation. If it is ineffective or s...
