Problems solved by technology

[0003] The catheterization of existing expansion catheters all depends on the personal skills of medical staff, and whether the catheter has been placed in place is judged by subjective intuition and experience, so the operation of catheterization is complicated, requiring high skills of doctors and the deviation rate of catheterization However, inaccurate catheter placement will cause part of the prostatic hyperplasia to be unexpanded, thereby reducing the effect of the operation. It may also cause urinary continence damage and urethral damage due to excessive expansion of the non-prostatic urethra, which will bring harm to the use. Inconvenience

Embodiment 1

[0035] like Figure 1-4 As shown, a kind of prostatic dilatation catheter comprises a main catheter 1; the diameter of the main catheter 1 is generally 5-8mm, and the length is 300-500mm, and the diameter of the front end opening of the main catheter 1 is 2-4mm; the main catheter 1 is provided with a ball The balloon water injection cavity 2 and the catheter main cavity 3; the back ends of the balloon water injection cavity 2 and the catheter main cavity 3 are respectively provided with a balloon water injection joint 20 and a catheter water inlet joint 10; the balloon water injection joint 20 and the catheter inlet The water connector 10 communicates with the balloon water injection cavity 2 and the catheter main cavity 3 respectively in sequence.

[0036] The outer diameter of the balloon 4 of the present invention is Φ6.36±0.05mm. After the expansion of the balloon 4, the cross-section of the balloon is a columnar structure with a length of 44 mm. The length of the balloo...

Embodiment 2

[0059] Both the balloon 4 and the main catheter 1 are made of fully transparent material, and the main catheter 1 is interspersed with an endoscope 5; and in this embodiment 2, the main catheter 1 is interspersed with an endoscope 5; the balloon 4 and the main catheter The tube 1 is made of fully transparent material. By controlling the endoscope 5 to look back, the position of the scale 13 on the surface of the main tube 1 can be observed. By determining the position of the scale 13, the precise positioning of the prostate expansion tube can be realized to avoid In the prior art, the positional deviation of the prostatic dilation catheter can be judged by touching the positioning protrusion or touching the positioning protrusion by pressing the perineum, which can improve the positioning accuracy and ensure the surgical effect.

[0060] For other contents of this embodiment, refer to Embodiment 1.

Abstract

The invention relates to a prostate dilation catheter, which comprises a main catheter, a balloon water injection cavity and a catheter main cavity are formed in the main catheter; a balloon water injection connector and a catheter water inlet connector are sequentially arranged at the rear end of the balloon water injection cavity and the rear end of the catheter main cavity respectively. The balloon water injection connector and the catheter water inlet connector are respectively communicated with the balloon water injection cavity and the catheter main cavity in sequence; a balloon is arranged at the front ends of the balloon water injection cavity and the catheter main cavity; the balloon and the main catheter at the front end of the balloon are made of transparent materials; the prostate dilation catheter is simple in structure and convenient in use, the balloon and the main catheter at the front end of the balloon are made of transparent materials, an endoscope is inserted into the main catheter in a penetrating mode, the main catheter and the balloon are matched with the endoscope, the use convenience of the endoscope is guaranteed, the thought of the observation view fieldof the endoscope is improved, the discomfort of the product in use is greatly reduced, the endoscope is used in cooperation, and the operation risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a method for using a prostate dilation catheter. Background technique [0002] Prostatic hyperplasia is one of the more common diseases in male elderly. With the increasing incidence of global aging population, the incidence of benign prostatic hyperplasia increases with age clinically, but clinical symptoms may not be manifested when hyperplasia occurs. In the early stage of benign prostatic hyperplasia, due to compensation, the clinical symptoms are not typical. With the aggravation of lower urinary tract obstruction symptoms, the clinical manifestations gradually become more obvious. The course of the disease progresses relatively slowly, and the onset time is difficult to determine. Clinically, the technique of transurethral balloon dilatation of the prostate is relatively mature for patients with benign prostatic hyperplasia. Transurethral columnar water...
