Description

The invention relates to the medical field and can be used for cleaning the inner walls of blood vessels.

There is a known ultrasound catheter consisting of an ultrasonic source consisting of a high frequency oscillator with a piezo-transducer, a serially connected mechanical vibration concentrator, a metal wire probe, wherein the free end of the metal wire probe is helical, and a mechanical oscillator and metal wire probe having a free end Spiral forms made of a single material of the same high elasticity, such as stainless steel, nickel, or their alloys (see LT patent No. 5248, A61 B 17/20, 2005).

The above-mentioned ultrasound catheter generates ultrasonic high-frequency oscillations, which cause an uncontrolled cavitation process in the liquid, which results in the formation of clots or cholesterol plaques on the walls into microparticles of varying size. The movement of particles is uncontrolled and can block the walls of further blood vessels.

There is a known method and apparatus for vascular cleaning comprising a cylindrical body having a ring with at least one permanent magnet or an electromagnet, a table sliding on a substrate into a blood vessel, a catheter or a microcatheter, a fluid consisting of paramagnetic nanoparticles imparted by a magnetic field a generator containing the entire human body, or otherwise only a part of the body (U.S. Patent No. 0142630 Al, 2006).

In the device referred to, the human body is placed on a movable table with a base, or part thereof, inside the cylindrical frame of a magnetic field generator, where the magnetic field is generated by permanent magnets or electromagnets rigidly fixed in or on the ring . A colloidal fluid introduced into a catheter or microcatheter, containing paramagnetic nanoparticles up to 100 nm in size, is controlled by an external magnetic field generator, providing the fluid with rotary or linear motion. The device is limited by the large size of the structure and the permanent magnets or electromagnets. In both stationary and portable embodiments, the magnetic field generated must be particularly strong to compensate for the distance between the magnetized ring in the cylindrical portion of the device and the patient's blood vessels. There is no way to change this distance. In the case of permanent magnets, the magnetic field generated can pose a risk to the environment, especially in the case of a portable device, as it cannot be switched off at the end of the cleaning operation and also prevents effective removal of cleaning fluid from the cleaning area by catheter or other intravenous device. , because all paramagnetic particles, along with abrasive and miscible thrombus particles in the cleaning fluid, would be exposed to a magnetic field, and when removed from the patient's magnetic field, all of said particles would be transported by a blood stream. In the case of electromagnets, the bulky size required to provide a sufficiently strong magnetic field in the cleaning area would require additional apparatus to cool them, and high power may pose an environmental hazard. For both unit models, the cleaning process can be time consuming. In the case of a portable device model with only a limb, the size of the device should be maximized to accommodate limbs of different diameters, which increases the power of the magnets.

The object of the invention is to increase the efficiency and reliability of vascular cleaning.

This object is achieved by providing a device for internal vascular cleaning consisting of a cylindrical body with circular drop-down cases with electromagnets movably attached to the body locking elements acting on the human limb in a cleaning area which is enclosed within a cylindrical body. in a cavity embedded with centering rods lowered by a centering ring, with centering rods rigidly attached on its outside, capable of rotating around an object at either end of the device, or fixed directly by centering rods at both ends of the device, in a blood vessel (chemically) nanoparticles (metal oxides) of the material, and an ultrasonic catheter with a helical working part, create a cavitation effect and a rotating electromagnetic field that acts on the blood vessels as paramagnetic nanoparticles less than 100 nm introduced by catheter or microcatheter.

The invention is explained in the figures, which show a device for internal vascular cleaning.

The device consists of a cylindrical body 1 with circular folding cases 2 with electromagnets 3 movably secured to the body by means of locking elements 4 acting in a cleaning area 5 which is enclosed in a cavity 6, a human limb 7 centered in a cylindrical cavity 8. by means of centering rods 9, lowered by centering ring 10, with centering rods firmly attached on its outside, capable of rotating around the object, either at the ends of the device or directly centered on both ends of the device, in a vessel aligned with the environment of the cleaning area (blood vessel) (chemically) nanoparticles 11 (metal oxides), and ultrasound catheter 12, with helical part

13. The housing 1 may be mounted on a solid support using brackets 14 at both ends or secured to an object, a human limb 7, by centering bars 9.

The device works as follows.

The device, which is mounted on a solid substrate using brackets 14 at both ends, or is mounted on a centering member of a cylindrical cavity 8 containing a human limb 7 or directly on a human limb 7 having a closed cavity 6 (vessel) containing a cleaning area 5. rods 9, at least three, all of which are lowered on one side by simultaneously rotating a centering ring 10 on that side. Electromagnet cases 2 (at least 3) with electromagnets 3 (at least 3) located in the cylindrical housing 1 to the cylindrical cavity 8 is a human limb 7 with a cleaning area 5 in a vessel 6, or directly down to a human limb 7 with a cleaning area 5 in the vessel 6 is lowered by means of the locking members 4 of the electromagnet tray 2 on at least one side of the electromagnet cases. The electromagnets are turned on. A special controller (not shown) is used to create a running electromagnetic wave to control the electromagnet. Nanoparticulate cleaning fluid 5 is introduced into the cleaning area 5 by means of a catheter or microcatheter (not shown). oscillations generated by the piezo converter cause cavitation. During the cavitation process, microbubbles are formed in the liquid, whose bursting energy destroys the plaque 15 on the inner walls of the vessel 6 into fine, non-uniform microparticles and partially removes the occlusion of the vessel. Exposure of paramagnetic nanoparticles 11 to the electromagnetic field increases the fluidity of the cleaning area. Due to the increased fluidity, fracture plaque fractions remain within the operating range of the dispersed paramagnetic nanoparticles and the magnetic field. The variable electromagnetic field creates a rotational motion of diffused paramagnetic nanoparticles which, when in contact with the splinters, crush them and clean the surface of the vessel more cleanly. Thrombus clumps and cleaning fluid with particles in the treatment area may be removed by catheter, microcatheter or other intravenous suction (not shown).

Compared to the prototype, a new set of structural elements, using an electromagnetic field generator, to create a variable electromagnetic field using an ultrasound catheter spiral working part to cause cavitation to shred the blood vessels to a nano size and to finally cleanse .
