Hip-joint endoprosthesis system - Google Patents

The endoprosthesis of the hip joint, containing the cavity, head, neck, leg, lining, consisting of movable elements, separated from each other by gaps placed between the surface of the head and the bottom of the trench, and corrugated cover made of elastic material, the sealing joint cavity filled with lubricating fluid, wherein the strip elements are made in the form of rings, stacked on top of each flat contact between the surfaces parallel to the end face of the cavity, the outer surfaces of the rings congruent inner surface of the cavity, the inner surface is the surface of the head element and the strip located between the p is lucumi heads and depression, made in the form of concave-convex meniscus spherical concentrically arranged surfaces, the upper, convex surface of this element congruent inner surface of the trench, and concave in the middle part of the bottom surface is the surface of the head, the flat bottom edge of the meniscus associated with flat edges of the underlying annular element, the gaps allow for the swinging movement of the elements of the strip between the surfaces of the head and depression, among themselves, as well as rotational movement around its own axis, while the elements of the gasket and head are held in a hollow flange flared, attached to the end of the depression, through a sealing gasket, corrugated cover is fixed on the edge of the flange and on the collar of the neck and the cavity of the pouch filled with the lubricating fluid through the openings in the flared flange is connected with the joint cavity formed by the gaps.

The device is used as follows. One of the known approaches reach the region of the hip joint and frees him from the capsule. Produce resection of the proximal femur. Prepare a bed in the bone-marrow channel under the leg 4 of the endoprosthesis, which are immersed in that bed, zakolachival or locking cement. After resection of the acetabulum establish and fix it pre-selected by the head 1, the prosthesis depression. Produce repositioning of the head of the endoprosthesis 1 in the prosthesis depression. The wound is sutured in layers.

Hip Replacement -Bipolar Endoprosthesis

The closest in terms of its technical solution claimed is hip replacement [5]. The device comprises a hollow head, separated from the trough lining, cervix, vertelney Department and leg. The seal is made of double-layer. The first layer is fixed on the bottom of the basin, made of elastic material has a microporous structure, and a second layer attached to the first, made in the form of polygonal plates of tribological resistant material, separated by a capillary cracks. The surface of the wafer adjacent to the first layer of strips, congruent its surface, and Mgr is suggesting to the head - congruent surface of the latter. Between the inner edge of the end face of the cavity and the cervical collar is placed fixed on them, elastoplastic case, forming a sealed cavity filled with lubricating fluid and a built-in through the micropores of the first layer strip with capillary slits separating plate. Through these cracks lubricating fluid is supplied to the friction surfaces.

This things is ity is the endoprosthesis of the hip joint includes a hollow head, neck, leg, lining, consisting of movable elements, separated from each other by gaps placed between the surface of the head and the bottom of the trench, and corrugated cover made of elastic material, the sealing joint cavity filled with lubricating fluid. The elements of the gaskets are made in the form of rings, stacked on top of each flat contact between the surfaces parallel to the end face of the depression. The outer surfaces of the rings congruent inner surface of the cavity, the inner surface of the head element and the strip located between the poles of the head and hollows made in the form of concave-convex meniscus spherical, concentrically arranged surfaces. The upper, convex surface of this element, congruent inner surface of the trench, and concave in the middle part, the bottom surface is the surface of the head. The flat bottom edge of the meniscus associated with flat edges of the underlying annular element. The gaps allow for the swinging movement of the elements of the strip between the surfaces of the head and depression, among themselves, as well as rotational movement around its own axis. Moreover, the elements of the strip and the head is held in a hollow flange flared, attached to the end of vPad the us through a sealing gasket. Corrugated plastic is fixed on the edge of the flange and the collar at the neck. The cavity of the pouch filled with the lubricating fluid through the openings in the flared flange is connected with the joint cavity formed by the gaps.

Hip endoprosthesis for in vivo ..

The data of Figure 2 show that in the studied period, the most demanded prostheses were
total prostheses (34 925 operations), representing 66.69% of the total number, followed by Moore prostheses (14 303 operations), 27.31%, and bi-polar prostheses (3145 operations), representing only 6% of the total number. In the evolution in time, during the eight years, an annual increase in the number of total hip endoprostheses, a slight decrease in the number of Moore prostheses, and a relatively constant number of bipolar prostheses can be seen.

The endoprosthesis of the hip joint that contains the head, neck, vertelney part, the stem and the axis, characterized in that it contains elastic elements and housings with internal conical surface, the axis is made variable cross-section with grooves on the surface located at an angle in the Department tubular legs evenly along the length of the fixed housing, and the axle is installed in the buildings with the possibility of longitudinal movement transmitted cylindrical part vertaling Department, the elastic elements are in the form of hollow bodies of revolution of an arc with longitudinal slots, equipped with end flanges, one of which is rigidly fixed n the area of the axis of the smaller diameter, and the other movable with fingers can move along the grooves, while the elastic elements cover axis on plots larger diameter and interact with internal conical surfaces of buildings.

For arthrosis of the hip joint, both the ball and the socket of the joint have to be replaced with an artificial joint, known as a total hip replacement (THR).Continuous improvement in both surgical techniques and the quality of implants since the 1960s make this procedure one of the most common and most successful routine operations in orthopaedic surgery, with a total of about 400,000 operations a year in Europe as a whole.The prosthesis is modelled on the actual human joint, i.e.
