Description

Urethra expansion strip

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a urethra expansion strip.

Background

Urethral stricture is a common urinary system disease mainly occurring in men, urethral dilation is the simplest method for treating urethral stricture, is one of important means for treating urethral stricture at present, and is widely applied to emergency treatment of urinary retention patients with urinary retention. Urethral dilation can also be applied to the complementary treatment of endoluminal or open surgery. The urethra expansion strip applied in the traditional urethra expansion operation is from small to large, the urethra needs to be repeatedly pulled and inserted for exploration and expansion, the process is complicated and time-consuming, the operation difficulty is high, and certain learning curves are needed; and the complications such as urethral mucosa injury, false tract formation and the like of the patient are easily caused, and the pain and the sense of fear of the patient are obvious.

Disclosure of Invention

An object of the utility model is to provide a urethra expansion strip makes urethra expansion operation become simple, easy, reduces the patient damage to can improve operation speed, reinforcing operation security effectively alleviates or alleviates patient's pain and fear and feels.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a urethra expansion strip, its is including expanding a main part, it is by main part and the integrated into one piece that bends to expand a main part, main part and the portion of bending are equipped with the seal wire passageway along its axis direction, can hold the seal wire of guide in the seal wire passageway, the outer wall of main part is equipped with expanding structure, expanding structure's one end is established in the junction of main part and the portion of bending, expanding structure's the other end and the water pocket valve intercommunication of establishing at the main part outer wall, be equipped with a plurality of drainage hole on the lateral wall of the portion of bending, drainage hole and seal wire passageway intercommunication.

Furthermore, the main body part is provided with a handheld part, the handheld part is provided with a first guide wire guide hole for a guide wire to pass through, and the tail end of the bending part is provided with a second guide wire guide hole for the guide wire to pass through.

Further, the aperture of the drainage hole is 2 mm.

The whole urethra main body can expand, and the central guide wire guide hole has the functions of guiding and drainage. The utility model discloses according to human urethra anatomical structure and clinical disease characteristics, design peculiar expandable contraction structure, the main part initial diameter of expansion strip main part is 4mm, and the anatomical features of bending under the urethra can be overcome in the design of the portion of bending, during the use, passes patient's urethra narrow part with tiny seal wire earlier, then can be very safely, conveniently with this novel uninflated urethra expansion strip is put into in the bladder urethra along the seal wire guide. In addition, the outer wall of main part is equipped with expanding structure, expanding structure's one end is established at the junction of main part and the portion of bending, expanding structure's the other end and establishing the water pocket valve intercommunication at the main part outer wall, can make the even inflation of expansion strip main part after leading to water through the water pocket valve, close the valve after the inflation reaches the expected value, the inflation maximum diameter is 9mm, the design accords with human physiological standard, avoids the damage, can play the expansion urethra, the constrictive effect of treatment urethra. After the treatment, the water sac valve is opened and the water is discharged, the expansion front structure can be restored. The center of the handheld part is reserved with a first guide wire guide hole (2mm) which has the dual functions of retaining a guide wire and draining urine. The lateral wall of the bending part is provided with a plurality of drainage holes communicated with the guide wire channel, the drainage holes are not parallel and annular, and the bending part has the function of preventing blockage of blood clots, floccules, cavity walls or other foreign matters. In addition, the expansion strip is arranged on the main body part, because the bent part can enter the bladder cavity after expansion, the length and the position of the narrow section cannot be evaluated when the urethral stricture is initially detected and drained, and the expansion strip is limited in use if only designed on the bent part or a certain local section of the main body.

The utility model discloses can avoid repeatedly pulling out and inserting the expansion strip in the urethra dilatation art, shorten operation time, effectively reduce complication incidence such as urethra mucosa damage, false lane formation, reduce or alleviate patient's pain, fear and feel, the urine is drained to urethra expansion simultaneously, relieves urine retention, has weak point consuming time, the damage is little, safe, convenient, economic advantage.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments;

fig. 1 is a schematic structural view of the urethral dilating strip of the present invention.

Detailed Description

As shown in fig. 1, the utility model relates to a urethra expansion strip, it is including expanding the strip main part, it is by main part 1 and 2 integrated into one piece of portion of bending to expand the strip main part, main part 1 is equipped with seal wire passageway 3 along its axis direction with the portion of bending 2, be equipped with seal wire 4 in the seal wire passageway 3, main part 1's outer wall is equipped with expanding structure 5, expanding structure 5's one end is established at main part 1 and the junction of the portion of bending 2, expanding structure 5's the other end and the water pocket valve 6 intercommunication of establishing at main part 1 outer wall, be equipped with a plurality of drainage hole 7 on the lateral wall of the portion of bending 2, drainage hole 7 and seal wire passageway 3 intercommunication.
