Support convenient for apparatus to enter urethra for treatment or detection

Abstract

The invention relates to a support convenient for an instrument to enter a urethra for treatment or detection, and belongs to the technical field of medical instruments, the support comprises a tube body, the tube body comprises an outer wall and an inner wall, the outer wall and the inner wall are sealed to form an annular cavity, the outer wall and the inner wall are both elastic films made of elastic materials, and the outer wall and the inner wall are made of elastic materials. An expansion structure is arranged in the annular cavity and comprises a plurality of supporting pieces fixed to the outer wall, the supporting pieces are arranged in the annular cavity in the circumferential direction at equal intervals, and an elastic piece is connected between any two adjacent supporting pieces. Through special design, the tube body has contraction capacity, the diameter can be increased to expand the visual field for treatment or detection during medical operation, and the diameter can be reduced to reduce the adhesive force to the urethral wall after the operation is completed, so that the tube body is easily withdrawn, and damage to the urethra is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a supporter with adjustable size for facilitating the device to enter the urethra for treatment or detection. Background technique [0002] The urethra is the passage through which urine is excreted. Irregular life may lead to urinary tract diseases such as frequent urination, urgency, and dysuria. For severe urinary tract diseases, the symptoms and causes can be confirmed by urethroscopic or urethrography, and finally treated by drugs or surgery. In the process of detection and treatment, it is necessary to insert the device into the urethra. In this process, because the size of the urethra is different, and the device is of a fixed size, it will inevitably cause discomfort. [0003] At the same time, detection or treatment usually takes a period of time. Because the outer wall of the device and the urethral mucosa are adhered to each other for a long time to gradually...

Problems solved by technology

[0005] In view of this, the purpose of the present invention is to propose a supporter for conveniently inserting instruments into the urethra for treatment or detection. The outer diameter of the supporter is adjustable and can shrink after use without causing damage to the urethra. To solve the problem that the existing technology may cause damage to the urethra due to the inability to adjust the size
