Urethra catheter for expansion of urethral canal and manufacturing method thereof

Abstract

The invention discloses a urethra catheter for expansion of a urethral canal and a manufacturing method thereof. The manufacturing method comprises the following steps of; (1) preparing a urethra catheter; (2) preparing a positioning device; and (3) preparing an expansion device. The invention also discloses a produced manufactured in the above method. The method is simple and can be realized easily, and the cost is low. The urethra catheter has a delicate design and reasonable structure. After the urethra catheter inserted into the urethral canal, the positioning device and the expansion device in a narrow state can be tightly attached to the outer wall of the urethra catheter, the outside diameter of the urethra catheter can be reduced effectively, and pains of patients can be eased; the urethra catheter can be effectively positioned in the bladder by the positioning device to facilitate positioning and expansion operations of the expansion device for a part to be expanded, an intermittent inflation or liquid filling method is adopted during expansion, the urethral canal can be expanded, urethral stricture can be treated, mucosal ischemic necrosis can be avoided, the surgical safety and effectiveness can be improved greatly, and the large-scale promotion and application can be facilitated.

Description

technical field [0001] The invention relates to the technology in the field of medical devices, in particular to a method for manufacturing a urinary catheter for dilating the urethra and products implementing the method. Background technique [0002] Urethral stricture is a difficult and common disease in urology, and urethral dilatation is an important means of examination and treatment. For this reason, design a kind of treatment equipment that can not only catheterize, but also can treat urethral stricture simultaneously more conveniently treat. At present, the catheters used in hospitals are usually made of latex or silicone tubes. Since the outer diameter of the catheter cannot be changed, if the design is too small, a gap will be formed between the outer wall of the tube and the urethra, resulting in urine leakage; The size is equivalent to the inner wall of the urethra, and it causes pain for the patient during insertion, especially for patients with urethral strict...

AI Technical Summary

Problems solved by technology

At present, the catheters used in hospitals are usually made of latex or silicone tubes. Since the outer diameter of the catheter cannot be changed, if the design is too small, a gap will be formed between the outer wall of the tube and the urethra, resulting in urine leakage; It is about the same size as the inner wall of the urethra, and it causes pain for the patient during insertion, especially for patients with urethral stricture or obstruction, and it is also difficult for medical staff to operate
