Abstract
The utility model discloses a prostate hyperplasia high-energy focusing ultrasound therapy catheter which comprises a catheter body (11), a fixed water sac (2) is arranged on the front part of the catheter body (11), a catheter (10) and a water outlet pipe (9) of a fixed water sac (2) are arranged in the catheter body (11), and the front end of the catheter (10) and the front end of the water outlet pipe (9) are respectively provided with an urethral catheterization opening (1) and a water inlet hole (3). The catheter is characterized in that a therapy water sac (5) is arranged on the middle front part of the catheter body (11), a water inlet pipe (8) and a water outlet pipe (7) of the therapy water sac are arranged in the catheter body (11), the front end of the water inlet pipe (8) and the front end of the water outlet pipe (7) of the therapy water sac are respectively provided with a water inlet hole (4) and a water outlet hole (6) of the therapy water sac, and the utility model has the advantages that catheter ultrasound positioning is accurate, and the damage of the inner film of the urethra prostate segment can be avoided.
Description
Technical field:
This utility model relates to technical field of medical instruments, is a kind of prostatic hyperplasia energy focusing ultrasonic-high treatment catheter specifically.
At present, along with the health of people level improves, the life-span prolongs and the aging of population structure, the prostatic hyperplasia of elderly men is more and more, has a strong impact on its quality of life.When the prostatic hyperplasia symptom is obvious, most patients have been worn with age, medication effect is not good, operative treatment has misery, also to consider people's whole body tolerance situation, though non-operative treatment can not fundamentally solve the hypertrophy problem, its safety, misery are less, short-term effect is good, and that carries out in recent years is more.Energy focusing ultrasonic-high (HIFU) treatment prostatic hyperplasia is a kind of emerging Therapeutic Method, and as emerging minimally-invasive treatment technology, development in recent years is rapid.HIFU treatment prostatic hyperplasia has following method: 1, body inner focusing type: per rectum placement in the treatment probe; 2, external focusing type: 1) through the stomach wall treatment, suitable filling bladder, external emission focus supersonic through preceding stomach wall incident, focuses on the prostate treatment zone; 2) through the perineum treatment, external generation is assembled ultrasonic, through perineal position incident, focuses on the prostate treatment zone.HIFU external focusing treatment prostatic hyperplasia was not plugged in catheter in the past, advocated to insert catheter in recent years, avoided postoperative urine pool to slip, rebuild the effect of prostate-urethra section to play.But the existing catheter location difficulty, the effect of unprotect urethra prostate section inner membrance.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of prostatic hyperplasia energy focusing ultrasonic-high treatment catheter is provided, and mainly solves problems such as existing catheter location difficulty, the interior membrane interaction of unprotect urethra prostate section.
In order to achieve the above object, this utility model is achieved in that prostatic hyperplasia energy focusing ultrasonic-high treatment catheter, it comprises the urethral catheterization body, establish fixedly water pocket in the front portion of urethral catheterization body, in the urethral catheterization body, establish catheter and fixing water pocket outlet pipe, front end at catheter is established catheterizing port, establish fixedly water pocket inlet opening at the fixing front end of water pocket outlet pipe, fixedly the water pocket inlet opening is in fixing water pocket, its special character is to establish the treatment water pocket at the middle front part of urethral catheterization body, in the urethral catheterization body, establish treatment water pocket water inlet pipe and treatment water pocket outlet pipe, establish treatment water pocket inlet opening and treatment water pocket apopore respectively at the front end of treatment water pocket water inlet pipe and treatment water pocket outlet pipe, treatment water pocket inlet opening and treatment water pocket apopore are in the treatment water pocket.
Compared with the prior art prostatic hyperplasia energy focusing ultrasonic-high treatment catheter described in the utility model has following good effect: 1, adopt the treatment water pocket, normal saline fills water pocket, water is the ultrasonic good medium of passing through, be beneficial to the demonstration of urethra prostate section, convenience for ultrasonic is accurately located, and avoids damaging urethra prostate section inner membrance; 2, normal saline be beneficial to the treatment focused ultrasound beams pass through; 3, low-temperature normal saline circulation in the treatment water pocket rises to reducing urethra prostate section temperature, and heat is transmitted to the urethra inner membrance when preventing the HIFU treatment, and protection urethra inner membrance is beneficial to post-operative recovery, avoids postoperative hemorrhage; When 4, HIFU treats,, make treatment water pocket internal pressure reach 3-5 atmospheric pressure, persistent period 10-20 minute, play the effect of inflated prostate urethra section by the temperature, pressure controller that outreaches; 5, the HIFU treatment finishes the back indwelling catheter, treatment water pocket pressure reduces to zero, after 3 days, the treatment water pocket pressurizes by normal saline, and hydraulic pressure is kept 0.5-1 atmospheric pressure, water temperature is kept 37 degrees centigrade, reach local physical therapy, the effect of blood circulation promoting, twice of every day, each lasting 1 hour, urethra prostate section is played the effect of plastotype, typing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe this utility model prostatic hyperplasia energy focusing ultrasonic-high treatment catheter in detail.
Prostatic hyperplasia energy focusing ultrasonic-high treatment catheter described in the utility model, during treatment, fixedly the water pocket water-filling is treated water pocket and is charged into degassing evacuation low-temperature normal saline, and the temperature, pressure controller by connecting outward, forms the low-temperature normal saline pressures cycle; With the ultrasonic probe location, carry out the HIFU treatment behind the location.
