Abstract
The urethra valve consists of two parts, built-in part and outer controller part. The built-in part is a tubular one with a clamp at one end and locking lid at the other end, three communicated cavities, and one screwed shaft at the center of cavities. Of the three cavities, the upper one has ball valve and spring; the middle one has a slip block nut connected to the screw shaft and its runner and reset spring acting onto partition and slip block nut respectively at the two ends; and the lower one has bearing holder and rotary magnet. The outer controller part has a magnet connected to reducing motor and a bi-directional power switch on the casing.
Description
The present invention relates to a kind of medical device (device), especially a kind of rotary magnet type urethra valve.
In actual life, urinary incontinence is that human urinary tract is comparatively common, but a unusual class disease of refractory.Often by congenital or posteriority brain, myeleterosis, factors such as male prostate postoperative and female bladder pressure cause, it causes great misery not only for patient's spirit, and might cause severe complications, even jeopardize patient's life, settling artificial urethra to expand about flesh is one of the main method that can at all deal with problems at present, but expand the implantation of all need performing the operation of about flesh at the artificial urethra of clinical practice in the world, complex structure, cost an arm and a leg, the plant failure rate is higher, and success rate only has about 80%, have in addition can cause serious sequela such as urethra necrosis.The normal closed gate that United States Patent (USP) 4909785 and the 5112306 urethra valves of introducing are made up of the liquid capsule and a cover drainage arrangement of mutability, when compressing liquid capsule, valve is open, and after delaying after a while, valve is closed automatically, so that the bladder emptying.But its structure of this device is too complicated, and volume is big, and may maloperation take place and leakage of urine when the improper pressurized of liquid capsule.3812841,5004454 and 5140999 of United States Patent (USP)s belong to magnetic driven, their common feature is the switching of its normal closed gate effect of body internal magnet to external magnetic field that place one's entire reliance upon, difference mainly is the difference of the model of action between its magnet valve door and controlling magnetic field, in 3812841, the opening of its magnet valve door is by the strength of external controlling magnetic field direct " pulling out ", for obtaining to resist the spring powered of normal closed gate, it is enough big that Magnet volume in the valve is wanted, and making it can't make maybe can't load and unload.5004454 simple in structure than 3812841, and volume is much smaller, opens normal closed gate for obtaining bigger strength, and it has utilized the principle of " lever ", so its valve internal magnet volume obviously reduces.But because its " lever " part is in valve, and valve has limited the sphere of action of " lever ", cause its valve open very for a short time, make urine stream very little, 5140999 and 5004454 is very alike, it mainly improves is to have to stretch out " frizzen " that valve enters bladder, thereby makes the opening of normal closed gate obtain bigger moment and range of opening.But the problem of bringing is owing to a Magnet " frizzen " is arranged than length and at its top, in time, may be trembleed in patient strenuous exercise (as running, jumping), and causing leakage of urine, its " frizzen " that stretches into bladder also may form because of foreign body stimulates the calculus that causes patient's bladder in addition.
The objective of the invention is a kind of be intended to solve the urinary incontinence due to the aforementioned a variety of causes and the rotary magnet type urethra valve of the illness such as dysuria due to the prostatic hyperplasia.
Technical solution of the present invention, it comprises the built-in part of urethra and the outer body 2 big parts of tube-like envelope, built-in part shell two ends are not of uniform size, its major part outer rim has the smart hole of letting out more than 2, two ends are respectively arranged with loading and unloading card and fore shaft lid, its type of attachment adopts screw thread, loading and unloading card and fore shaft lid, and the center has arcuate socket (how much holes).Built-in part is provided with cavity, big cavity i.e. (following cavity) is bigger, act on the major part part, little head part has 2 cavitys, be upper plenum and cavity, 3 cavitys are communicated with each other, middle 2 dividing plates and the nut fore shaft of adopting is separated by, have the hole that differs in size on the dividing plate, screw shaft (5) acts on the central authorities of 3 cavitys, and it is provided with specific spacing length screw thread, to prevent valve opening or lock-up condition when closing, ball valve and spring that its top has locating hole act directly on upper plenum (proximal part), and spring action is between ball valve and fore shaft lid.The slider nut that is connected on the screw shaft is arranged on the cavity, slider nut is bearing in the chute on the shell, slide block number on it is corresponding with chute, chute also can claim the spermatorrhea groove, the urinating when setting of slider nut can guarantee that valve working that any reason causes is unusual, the back-moving spring two ends act on respectively on dividing plate and the slider nut, following cavity (distal end) is provided with the support of bearing and rotary magnet, support of bearing center is provided with a garden platform and a center drilling, adopt the female thread of screw thread and shell to be connected, have four along the round platform symmetry and be with arcual hole.External control section is connected with motor with coaxial reduction gearing by Magnet, power supply is subjected to the two-way switch control break-make on shell and changes rotation direction, because whole device has utilized rotating excitation field screw rod principle, making rotatablely moves changes rectilinear motion into, thereby obtained bigger straight-line strength by rotatablely moving of causing of less strength, realized that this big strength obtains effective control of valve and minimizing valve volume and weight very important by energy delivery and effective control of external control section to the non-direct contact type the built-in part of urethra.
The present invention has following advantage compared to existing technology:
1, utilizes the rotating excitation field principle, guaranteed the energy delivery of non-direct contact type and effectively control between 2 big parts in external and the body; Utilize the screw rod principle, making rotatablely moves changes rectilinear motion into, thereby has obtained big rectilinear motion strength by rotatablely moving of causing of less strength.
2, this device is provided with the spacing anti-locking device of screw thread, has avoided valve opening or the lock-up condition when closing the time, has guaranteed the timely unlatching of valve again or closes, and has realized the effective control to valve.
3, this device is provided with emergency set, thereby guarantees to urinate when the valve working that causes in any reason is unusual.
4, this device is provided with and lets out hard-cover and put, thereby does not influence male patient's ejaculation process.
5, this device reliable design, urinate conveniently, simple in structure, cheap, volume is little, in light weight, easy installation, advantage such as detachable, is a kind of state-of-the-art urethra valve both at home and abroad at present.
