Embodiment Construction

[0010] In this example, refer to figure 1 As shown, a urethral dilator with a catheter includes a dilation tube 1, a handle 5 and a catheter 3, the dilation tube 1 is provided with a through hole 2, and the handle 5 is provided with an inflation hole 4, so The catheter 3 is set in the expansion tube 1, the through hole 2 is set on the top of the expansion tube 1, the handle 5 is connected to the bottom of the expansion tube 1, and the catheter 3 is set in the expansion tube 1 through the through hole 2, so that The diameter of the catheter 3 is smaller than the diameter of the through hole 2, and the expansion tube 1 is a sealed hollow expansion tube.

[0011] The catheter 3 is divided into a head end (not shown) and a tail end (not shown), the head end passes through the through hole 2 from the top of the expansion tube 1, and the tail end is arranged outside the handle 5, so The diameter of the catheter 3 increases sequentially from the head end to the tail end.

Abstract

The invention discloses a urethral dilator with a catheter. The urethral dilator comprises a dilation tube, a grab handle and the catheter. A through hole is formed in the dilation tube, an inflation hole is formed in the grab handle, the catheter is arranged in the dilation tube, the through hole is formed in the top of the dilation tube, the grab handle is connected with the bottom of the dilation tube, the diameter of the catheter is smaller than that of the through hole, and the dilation tube is a sealed hollow dilation tube. The urethral dilator with the catheter has the advantages that the urethral dilator is provided with the arc-shaped catheter and accordingly can be easily fed into the urethra of a patient; the dilation tube can be easily fed into the urethra of the patient under the traction effect of the catheter; the diameter of the catheter is smaller than that of the through hole, so that a urethral catheterization hole can be omitted; the urethral dilator is provided with the sealed hollow dilation tube, the inflation hole is formed in the grab handle, and air can be inflated into the dilation tube, so that the diameter of the dilation tube can be increased, the urethra of the patient can be dilated at one step without replacing dilators with different diameters, the urethral dilator can be inserted into the urethra of the patient advantageously, and the urethra dilation safety can be effectively guaranteed.

Description

technical field [0001] The invention relates to a urethral dilator with a catheter. Background technique [0002] Urethral dilatation is a common method in urology for the treatment of urethral stricture. The traditional urethral dilator is a hollow urethral dilator, which includes a series of metal rod dilators with different diameters. For the pain of the patient, it is necessary to first dilate the urethra with a dilator with a smaller diameter. In order to avoid retraction of the urethra after the initial dilation, the diameter of the dilator must be gradually increased to achieve complete dilation of the urethra. In the second process, the dilator is inserted into the urethra completely by experience and feel, and gradually replacing the dilator with a larger diameter will bring pain to the patient many times. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a urethral dilator with a catheter that facilitat...
