Description
Technical field
The present invention relates to prostate dilation operation medical instruments field, more particularly to a kind of adjustable compound columnar water of convex
Capsule prostate dilator.
Background technology
Hyperplasia of prostate (BPH) is the common benign lesion of elderly men.The incidence of disease of more than 60 years old accounts for 65%, 25%
Clinical symptoms, which occurs, in patient needs medicine or surgical intervention.It is traditional through urinary bladder prostate gland enucleation or TURP, laser surgey effect
It is to determine, but it is larger to patient's strike to perform the operation, and the elderly is to body ability to bear and psychological bearing capability phases of operation
To poor, therefore many gerontal patients fear operation.It is long-term to be maintained by inserting urinary catheter, or even suprapubic cystotomy is only done come the row of solution
Urine is difficult.Quality of life extreme difference.Hyperplasia of prostate is treated using Posterior urethral dilation operation, is that current medical field answers valuing researches to treat
The method of hyperplasia of prostate.
The adjustable composite columnar aqueous capsule prostate dilation catheter of convex of the prior art is roughly divided into following three class：
1st, for the ease of insertion, most of adjustable composite columnar aqueous capsule prostate dilation catheter of convex in the prior art
External capsule is rounded, spherical, arc or streamlined etc., its structure is as shown in Figure 1.
2nd, the adjustable compound column water pocket of the apllied Application No. CN201010578449.8 of the applicant convex
