摘要：
The invention relates to medical engineering and can be used in the tests of the hip joint prosthesis in traumatology and orthopedics, which are carried out hip replacement surgery. This high-tech surgical intervention to replace one or all (total) hip components with artificial parts called endoprosthesis, with a view to restoring its function and pain relief.The technical result of the use of the claimed technical solution is the establishment of an effective testing device hip endoprosthesis in the axial compression by expanding the functionality of it by determining the critical forces in which the endoprosthesis cup swivel component installed with varying degrees nedopokrytiya loses load-bearing capacity under compression, that allows you to accurately judge the degree nedopokrytiya cup endoprosthesis, as one of the factors affecting the mechanical stability and load-bearing capacity of the implant, and to be more free in the choice of surgical approach when implanted acetabular cup endoprosthesis.The device is mounted in the clamps of the testing machine 110M CF-100, creating axial compression up to 100 kN, with varying loading rate. The lower clamping plate 1 is attached, which has reinforcing ribs and slots, which is set and fixed cylindrical sleeve 2. The glass is inserted into the leg prosthesis 2 and 5 is filled with a low-melting alloy Wood. The slot in the plate 1 allows the positioning of the glass 2 in the radial direction. The upper clamp is attached flat sector 4 with a slot in which the fixed cylindrical head 5. This connection allows the head tilted with respect to the compression axis. By the cylindrical head 5 mounted cylinder with an oblique cut 6, consisting of a set of detachable parts, sectors 9, in a plane oblique cut is made spherical recess, which houses the head of the endoprosthesis 10, the liner 8 and the cup 7, which form the acetabulum component. 4 ill.Полезная модель относится к медицинской технике и может быть использована при испы
