Problems solved by technology

However, this utility model lacks the function of measuring the length of the urethral stenosis, the diameter of the stenosis and the distance between the stenosis and the external opening of the urethra, and at the same time lacks the function of collecting materials for urethritis secretions and stones

Embodiment 1

[0028] Such as Figure 1-2 As shown, a urethral dilator is composed of a scout 1, a connecting rod 2 and a dilation tube 4 connected in order from left to right. The right end of the connecting rod 2 is sleeved with a tapered dilator 3, and the top of the tapered dilator 3 Towards the scout 1, the bottom faces the expansion tube 4; the cone dilator 3 has a hollow bowl-shaped structure, and its length is shorter than the connecting rod 2. The bottom diameter of the cone dilator 3 is larger than the cross-sectional diameter of the connecting rod 2; the expansion tube 4 is composed of a conical connecting end 4.1 and a cylindrical tube body 4.2 connected sequentially from left to right. The connection point between the connecting end 4.1 and the connecting rod 2 is located at the center of the bottom surface of the conical expander 3. The diameter of the bottom surface of the connecting end 4.1 is the same as the diameter of the bottom surface of the tube body 4.2, and the diamete...

Abstract

The invention discloses a urethral calibrator expander formed by a spherical probe (1), a connection rod (2) and an expansion tube (4) orderly connected from left to right. The right end of the connection rod (2) is covered with a tapered expanding device (3); the top of the tapered expanding device (3) faces the ball probe (1) and the bottom faces the expanding tube (4); the interior of the tapered expanding device (3) is in a hollow-bowl structure; the length of the tapered expanding device (3) is shorter than the connection rod (2); and the diameter of the bottom surface of the tapered expanding device (3) is greater than the diameter of a cross section of the connection rod (2). The narrow part of the urethral stricture can be effectively probed; the diameter and the length of the narrow part can be measured; relative reference information is provided for urethrostenosis surgery treatment and surgical method; meanwhile, pains of a patient and damage to the urethral stricture due to the exchange of various types of urethral calibrator expander can be reduced as possible as can; a material drawing performance for urethral stricture inflammatory excreta and stones can be met; and inspection and clinical treatment guide can be facilitated.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and particularly relates to a urethral dilator. Background technique [0002] Urethral stricture after hypospadias is a common complication. Urethral stricture mostly occurs at the urethra of the head of the penis and the proximal urethral anastomosis. The main cause of the proximal urethral anastomotic stenosis is the poor blood supply of the formed urethra. The anastomosis is not anastomosed. And so on. About 1 month after hypospadias, the scar is the most severe period, which can cause transient urethral stricture. In severe cases, it can be secondary to urethral diverticulum. Urinary scale and stones often accumulate in urethral diverticulum, which can easily cause urinary tract infection. For those with obvious urethral stricture, urethral dilatation can be used for early stenosis within 3 months after surgery. In case of invalid or severe cases, urethral stricture should be incised or the narr...
