Abstract
The utility model relates to a three-cavity high pressure air sac expansion and dilation catheter for prostate, which belongs to a medical apparatus for treating hyperplasia of prostate. The utility model is composed of a three-cavity soft catheter (6), a high pressure air sac (3) and a positioning air sac (5); the three-cavity soft catheter (6) is provided with the cavity of an urethral catheter (1), the cavity of the high pressure air sac (2) and a positioning cavity (4). The high pressure air sac (2) and the positioning cavity (4) are arranged in the catheter wall of the soft catheter (6) of the periphery of the cavity of the urethral catheter (1) in latent way. The utility model has large expansion range, and thus the dilation of the membranous part of urethra can be carried out; the outer surface of the catheter is smooth, and when the catheter is inserted into the urethra, the pain of the patient can be lightened; the inner diameter of the cavity of the urethral catheter is larger, which is favorable for discharging urine liquid, blood clots or thick clots; the utility model also has the advantages of good curative effect, convenient operation, simple positioning, low cost, etc.
Description
This utility model relates to a kind of three chamber high-pressure gasbag prostate expansion dilators, belongs to the medical apparatus and instruments for the treatment of hyperplasia of prostate.
At present, adopt the technology of urethral dilatation treatment hyperplasia of prostate that the sacculus shaping catheter is arranged, the metal tube hidden is withstand voltage air bag prostate dilator, its common drawback is that the expansion scope is little, classify all as expansion with middle period glandular hyperplasia person and prohibit disease, the expansion back is changed Foley catheter and can not be finished expansion back urethral catheterization, and when operation, need X-ray machine or anus to examine the location, the operation sequence complexity.Though the four chamber high-pressure gasbag prostate dilating catheters that patent documentation CN2088875N is provided have solved the shortcoming that said two devices exists, but the expansion scope is still little, the counterweight glandular hyperplasia and and to have middle period glandular hyperplasia and detrusor function to lose compensatory person's therapeutic effect undesirable, in urethral catheterization lumen, be provided with the flushing chamber, the urethral catheterization lumen internal diameter is reduced, be unfavorable for urine, clot or dense discharge, and show that an air bag and positioning gasbag are rough with the interface of conduit, when operation, bring misery to patient.
The purpose of this utility model provide big, the practicable membranous part of urethra of a kind of expansion scope expand split, conduit smooth in appearance, bigger, simple to operate, the eutherapeutic three chamber high-pressure gasbag prostate expansion dilators of urethral catheterization lumen internal diameter.
The purpose of this utility model is achieved in that it is made up of the three chamber soft body catheters (6) that contain urethral catheterization lumen (1), high pressure gas blister cavities (2), positioning chamber (4) and high-pressure gasbag (3) and positioning gasbag (5), and high pressure gas blister cavities (2), positioning chamber (4) are dived and be located in the tube wall of the peripheral soft body catheter (6) of urethral catheterization lumen (1).Outer cover at soft body catheter (6), high-pressure gasbag (3) and positioning gasbag (5) is provided with flexible rubber hose (10), and tube head one side is provided with the opening (7) of urethral catheterization lumen (1).
Behind urethral catheterization lumen opening (7), be provided with positioning gasbag (5), the opening (8) of positioning chamber (4) is arranged in the positioning gasbag (5), behind positioning gasbag (5), be provided with high-pressure gasbag (3), the opening (9) of high pressure gas blister cavities (2) is arranged in the high-pressure gasbag (3).
Diameter was 2.6-3.8cm after high-pressure gasbag of the present utility model (3) expanded, and length is 6-12cm.
Three chamber high-pressure gasbag prostate expansion dilators described in the utility model can be moulded or other soft material is made by silicon.Be furnished with metal inner core and the gas injection tube that has Pressure gauge and air valve in use.
This utility model compared with prior art has the following advantages:
1. expansion scope is big, and the practicable membranous part of urethra expands and splits, make heavy glandular hyperplasia and and have middle period glandular hyperplasia and detrusor function to lose compensatory tradition expansion contraindication to become indication of the present utility model, therapeutic effect is good;
2. owing to the outer cover at soft body catheter, positioning gasbag and high-pressure gasbag is provided with flexible rubber hose, so whole conduit smooth in appearance when inserting urethra, has alleviated patient's misery;
3. the urethral catheterization lumen internal diameter is bigger, helps urine, clot or dense discharge;
4. easy to operate, the location is simple, cost is low.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of the A-A direction of Fig. 1.
Below in conjunction with accompanying drawing this utility model is further described.
As Fig. 1, shown in Figure 2, this utility model is by containing urethral catheterization lumen (1), high pressure gas blister cavities (2), three chamber soft body catheters (6) of positioning chamber (4) and high-pressure gasbag (3) and positioning gasbag (5) are formed, urethral catheterization lumen (1) is the main chamber of soft body catheter (6), periphery in urethral catheterization lumen (1), dive in the tube wall of soft body catheter (6) and be provided with high pressure gas blister cavities (5) and positioning chamber (4), in soft body catheter (6), the outer cover of high-pressure gasbag (3) and positioning gasbag (5) is provided with flexible rubber hose (10), tube head one side of soft body catheter (6) is provided with the opening (7) of urethral catheterization chamber (1), it is positioning gasbag (5) thereafter, be provided with the opening (8) of positioning chamber (4) in the capsule, positioning gasbag (5) back is high-pressure gasbag (3), be provided with the opening (9) of high pressure gas blister cavities (3) in the capsule, diameter was 2.6-3.8cm after high-pressure gasbag (3) expanded, length is 6-12cm, the rear portion diameter is less, becomes certain tapering.
The method of manipulating of the present utility model is: press surgery asepsis routine operation, patient's integral body clinostatism of making even, with the divulsor dilating urethra to 24F, continue the metal inner core is inserted urethral catheterization lumen (1), with the outer lubricant that is coated with of soft body catheter (6), per urethra inserts bladder, the gas injection tube is connected with positioning chamber (4) and gas injection, positioning gasbag (5) gas injection is expanded, leading soft body catheter (6) outward makes positioning gasbag (5) be butted on bladder neck, then the gas in the positioning gasbag (5) is bled off, again soft body catheter (6) depth is inserted 2cm, then the gas injection tube is connected with high pressure gas blister cavities (2) and gas injection, the rear portion of open high-pressure gasbag (3) tapering should stride across membranous part and produce to expand and split at this moment, continue 1-5 minute, extract the metal inner core out, urine flows out unobstructed, can take over by the icarceration air flue, remove the gas injection tube, on penis, connect Drainage urine bag with immobilization with adhesive tape conduit (6).
