Prostate expanding catheter realizing visual locating

Abstract

The invention provides a prostate expanding catheter realizing visual locating. The prostate expanding catheter realizing visual locating comprises a main catheter, a soft lens and a composite high-pressure bag, wherein a urine guide cavity, a flushing cavity, an inner bag cavity and an outer bag cavity are arranged inside the main catheter, an opening is formed in the front end of the main catheter, the urine guide cavity and the flushing cavity are connected with the opening, and a positioning bulge is further arranged on the main catheter; a composite high-pressure water bag is arranged between the positioning bulge and the opening, the composite high-pressure water bag comprises an inner bag and an outer bag, the inner bag is located in the outer bag, and one or more marking lines with different colors are arranged on the outer bag; the soft lens can be inserted into the urine guide cavity or the flushing cavity of the main catheter. According to the prostate expanding catheter realizing visual locating, the marking line(s) on the outer bag can be observed through the soft lens inserted in the urine guide cavity, then the main catheter is located through the position of the marking line (s), thus the locating accuracy of the main catheter is improved, and meanwhile, the judgment of medical staff for the locating of the catheter is also facilitated.

Description

technical field [0001] The invention relates to the field of medical equipment for prostate dilation, in particular to a visualized and positioned prostate dilation catheter. Background technique [0002] Prostatic hyperplasia is a common disease in middle-aged and elderly men. The so-called benign prostatic hyperplasia is mainly due to the hyperplasia of the prostate tissue, resulting in an increase in its volume, which in turn squeezes the surrounding organs, resulting in a smaller and narrower urinary tract, resulting in dysuria, frequent urination, Prolonged urination and other symptoms. The traditional treatment method is to cut the prostate tissue, but the operation is a big blow to the patient, and the elderly's physical and psychological tolerance to the operation is poor, so they are unwilling to accept the operation. At present, the more advanced treatment method is prostate expansion surgery. This treatment operation is to insert the prostate expansion catheter i...

Problems solved by technology

[0003] However, the problem of inaccurate positioning of the prostate expansion catheter is common. During the operation, the medical staff rely on their supervisor's intuition and experience to judge the expansion by touching the positioning convex at the tip of the prostate through digital rectal examination or by touching the positioning convex on the perineum with finger pressure. Where the catheter is advanced in the body

However, due to the different body shapes of patients, for obese patients, the doctor cannot sense the convex position well during the operation, resulting in inaccurate positioning of the catheter, so that part of the prostatic hyperplasia is not expanded, which reduces the effect of the operation. May also cause urinary continence and urethral damage due to excessive dilation of the non-prostatic urethra
