SU238090A1 - BALL PROSTHESIS OF ATRIAL VENTRICLE VALVES OF THE HEART WITH A DEVICE FOR MECHANICAL FIXATION - Google Patents

Description

In the autonomic auth. St. No. 180749 describes a ball lobe of the ventricular-ventricular heart valves with a device for mechanical fixia, containing a hollow cylindrical body with closed guide channels for needles, a needle crown with two PIs | Yes, needle needles, ball-throw barriers and internal stops ball. When the Vendian moves along the axis of the broth, the longer needles of the inner row of the needle crown enter the guide channels of the body, and, acquiring a bend of a given radius, Stitch the cuff and the 1 strap, not the cloth; the short needles move in this way. the mA-linearly towards the end of the bending long needles. In the area of fixation of the prosthesis, where there are injured tissues, it is possible that there is increased thrombus formation.

The proposed prosthesis for the purpose of | umansheni thrombosis in the fixation zone of the 1nabnage is encircled with a circular ring made of synthetic material (material, nairi.merflux, hundred-4, with a collar entering into the collar of the double needle weights.

For mounting on the masonry after the installation of Pro, a clause | H containing it (HALF, internal cylindrical measles, a mustache with an annular groove and L-shaped and | slots for SVYaI with an emphasis of the case of the projec, the outer glass moving a cylindrical body and a spring associated with it, and body handles extending into the side slots at the bottom of the glass.

The key that controls the fixture of the fur, the physical fixation of the prosthesis, contains the cylindrical holder of the prosthesis body, which extend from the holder, the tori of the body, the needle crown retainer in the form of a rotary station, a canal, an internal shoulder,

a hollow cylindrical handle reinforced under a direct angle to the holder with an internal control rod for fixing devices embedded in it and a lever for moving the needle clamp, that rim relative to the prosthesis body holder, that is hinged to the handle.

fnksa | TS 1 and a streamlined ring lining; in fig. 3-1KEY for securing the lining; in fig. 4 - key, h for installation of the irothez and control of the mechanical device, fixation.

The prosthesis contains a hollow cylindrical body 1, at the end of which is located the saddle of the valve, the rod, the struts 2 of the ball stroke limiter 3, three -nopa 4, which prevent the ball from seizing in the saddle, and the double needle shaft of the prosthesis have radial guide channels 6 in which long needles of the double needle crown 5 are inserted.

The double needle crown 5 has shoulders 7 for communication with a key (see Fig. 4), a control device for mechanical fi1; sadia prosthesis, and with a ring lining 8 (see Fig 2), preventing thrombosis.

All parts of the nrotez are made of biologically inert materials: titanium alloys, silicone rubber, fluoroplast-4 and polyurethane foam.

The key controlling the fixation of the mechanical fixation of the prosthesis consists of a cylindrical holder 9, on which the irothez body 1 is fitted, the prosthesis fixers 10, for fastened in a cylindrical holder, a double needle crib 5, a movable lever 12, a non-moving handle 13 and an iKHO —Packs 14 of the inner gig 15, controlling the operation of the latches 10 and 11.

The parts of the key that fix the prosthesis and control its operation are located at the right angle to each other.

In the tissues of the heart, the prosthesis is fixed as follows.

The body 1 of the prosthesis is put on the cylindrical holder 9 with the button 14 & contact with the handle 13. In this position, the buttons of the shoulder of the retainer // fall into the slots between the shoulders of the double needle crown 5, and the retainers 10 do not protrude beyond the surface of the cylindrical holder 9. Having put on the button 14, they are pulled upwards.

At the same time, the retainers 10 are pushed out of the holder 9 and the retainer 11 is deployed so that its shoulders are connected to the double needle needle shoulder 7 by a 5-bayonet lock.

The prosthesis on the key is inserted into the heart in such a way that the body / cavity is lagged in the ventricular cavity, and the double needle crown is inserted into the atrium.

Then the lever 12 is pressed against the handle 13. At the same time, the double needle crown 5 moves in the direction to the body 1. Its long needles pass along the guides of the channel 1 M 6 and exit the load with a bend of the radius given by these channels. The short needles of the double needle crown move straight towards them. In this way, the prosthesis is fixed in the tissues of the heart with two rows of needles from the side of the ventricle and atrium.

When the prosthesis is completed, the button, the button 14, presses to the fixed handle 13. In this case, the lock 11 is unfolded and at the same time the screws 10 are hidden inside the cylindrical holder 9. After this, the key is removed.

double needle rims from the bloodstream, after the prosthesis is fixed in the heart tissues, a streamlined annular lining 8 of fluoroplastic-4 with a shoulder is attached to the double needle rim to communicate with the double needle crown. The pack is fixed on the prosthesis with the help of a special key (see Fig. 3), consisting of an inner cylinder 16 and a cup 17, connected

spring / 8 and handles 19 of the inner cylinder 16, inserted into the side slots of glass P.

The inner cylinder 16 has a hole 20 for communication with the stops 4 of the body 1 of the prosthesis and

annular groove for lining 8.

Slip 8 is put on the annular recess of the inner cylinder 16. Then the key is fixed with a bayonet grip on the stops 4. When mixed, the handle 19 with the bottom of the cylinder

18, the latter engages the shoulder of the lining 8 with the shoulders 7 of the double needle crown 5. Then the tread key is removed. If the denture is not properly attached, it can be removed and removed.

To this end, the prosthesis is again secured on the key and the handle 13 and the lever 12 are pushed apart with the blade of the additional handle.

After the implantation of the prosthesis, he will again work.
