Abstract

The utility model relates to a urethral support for hyperplasia of prostate. The shape of the sustainer is matched with the hyperplasia and deformation prostatic urethra. The middle end is round cylinder. The front end and back end of the cylinder are valgus flat or irregular surface in order to be adapted to the various states of the prostate before or after prostatic hyperplasia. The utility model has the advantages of favorable support elasticity, displacement resistance, mesh and net bud hyperplasia prevention, and good histocompatibility, without any rejection, inflammation reaction, carcinogenesis or teratogenicity.

Description

Prostatic hyperplasia urethral support thing

Technical field

This utility model relates to a kind of medical product, is mainly used in the Urology Surgery specialty, and the treatment prostatic hyperplasia causes the patient of blocking, and can support outgrowth prostate-urethra after inserting, and releasing is blocked.

Background technology

Hyperplasia of prostate is commonly encountered diseases, the frequently-occurring disease of middle-aging male, and clinical statistics represents, during 40-79 year, the sickness rate of hyperplasia of prostate is about male's sickness rate more than 50%, 80 years old then up to 80%.At present hyperplasia of prostate is mainly adopted method treatments such as medicine, operation.Drug therapy exists the course of treatment long, and the effect instability can not be effected a radical cure fully; Operative treatment then most patients can not tolerate, and especially suffers from cardiovascular disease and older patient, has certain risk.Placing a supporter at outgrowth prostatic urethra, reach the purpose that treatment is blocked as a kind of permanent stents, is a kind of non-medicine non-operative treatment safe and effective, easy and simple to handle.The supporter that uses mostly is the tubular support of memory alloy wire braiding at present, because the producer does not understand the form of prostate-urethra after the hypertrophy, how can not join with its kiss, its result can not reach effective support, and perhaps postoperative generation support is shifted and affects the treatment in the art; Owing to each elasticity inequality of the improper barrel of weaving method, mesh is too big in addition, and mesh granulation hyperplasia at a specified future date causes blocking also once more happening occasionally.These have all had a strong impact on therapeutic effect.

Summary of the invention

Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, and a kind of permanent supporter prostate-urethra form after the hypertrophy, anti-displacement, anti-mesh granulation hyperplasia that is suitable for is provided.

Supporter of the present utility model is achieved by following technical proposals, the profile that described supporter has the prostate-urethra with the hypertrophy after strain to match; Its middle-end is a rounded cylindrical, and the front end of cylinder is concordant or irregular that turns up with the rear end, to adapt to the variform of prostate after the hypertrophy.

Described cylindric supporter adopts tinsel left and right sides spiral interlacing or colludes with forming, and barrel is the fine mesh structure of tool uniform elastic.Eyed structure can form with rhizoid braiding, and also available multi-filament is knitted system, and the welding of can joining of the initiating terminal of silk and whole end also can dissociate, in order to dismounting.

Described supporter can be made from a variety of materials, and as memorial alloy, stainless steel silk, also can be silicone rubber, silica gel or soluble material, also can be the tinsel plated film and makes.

This utility model supporter has following beneficial effect compared with prior art:

1. configuration design is reasonable, becomes the profile of the prostate-urethra of table after the suitable hypertrophy, can support fully and effectively, and it is reliable to remove the exact efficacy of blocking.

2. the Fixed Design of anti-displacement has guaranteed that late result is good.

3. weaving method is reasonable, makes the barrel uniform elastic, adds that the fine mesh structure has prevented concurrent mesh granulation hyperplasia.

Description of drawings

Accompanying drawing has been described the embodiment of a kind of marmem supporter of this utility model design.

Fig. 1-the 3rd, the side view of three kinds of different end face supporters of this utility model design.

Fig. 4 is the vertical view of a kind of irregular end face supporter of this utility model design.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

As described in Figure, one of architectural feature of the present utility model is to adopt cylinder-shaped bracket two ends pleomorphism structure, to adapt to the variform at prostate-urethra two ends after the hypertrophy, design the projection screen of near-end 1/3 girth as the middle lobe hyperplasia person, middle period adds a lateral lobe and increases the projection screen that the survivor designs two 1/3 girths of near-end, and posterior lobe increases the survivor and designs projection screen of far-end 1/2 girth or the like.Two of architectural feature of the present utility model is that the cylinder two ends all have one one-tenth horn-like flange, prevents the supporter displacement in the prostate in order to embed, and prevents postoperative displacement in the art.Three of architectural feature of the present utility model is supporter employing tinsel left and right sides spiral interlacings or colludes with forming that barrel is the fine mesh structure of tool uniform elastic.Its eyed structure can form with rhizoid braiding, and also available multi-filament is knitted system; The initiating terminal of silk and the welding of can joining of whole end also can dissociate, in order to dismounting.

Claims

1. treat the supporter that hyperplasia of prostate causes urethral obstruction for one kind, it is characterized in that: the profile that described supporter has the prostate-urethra with the hypertrophy after strain to match; Its middle-end (2) is a rounded cylindrical, and the front end of cylinder (1) is concordant or irregular that turns up with rear end (3), to adapt to the variform of prostate after the hypertrophy.

2. a kind of supporter that hyperplasia of prostate causes urethral obstruction for the treatment of according to claim 1, it is characterized in that: said cylindric supporter adopts tinsel left and right sides spiral interlacing or colludes with forming, and barrel is the fine mesh structure (4) of tool uniform elastic.

3. a kind of supporter that hyperplasia of prostate causes urethral obstruction for the treatment of according to claim 2, it is characterized in that: the braiding of the available rhizoid of eyed structure (4) forms, and also available multi-filament is knitted system, the welding of can joining of the initiating terminal of silk and whole end, also can dissociate, in order to removing.

4. according to the described a kind of supporter that hyperplasia of prostate causes urethral obstruction for the treatment of of claim 1 to 3, it is characterized in that: described supporter can be made from a variety of materials, as memorial alloy, stainless steel silk, also can be silicone rubber, silica gel or soluble material, also can be the tinsel plated film and make.
