(54) TESTING DEVICE FOR LOWER HOSPITAL PROTESTS

4 in arc-shaped grooves, 3 are placed in the middle, and the spread: then outside the mazhdu kolykhamv was equal around the entire circumference and reached 25-ZO mm. A metal receiving sleeve is inserted into the composite ring, and a metal cup 12 of the knee assembly, the height of the prosthesis, is turned into the ring 5 - metal cup 12 of the knee assembly. The screws 6 fix the device to the prosthesis so that the connecting pads

The receptacle and the cups of the knee knot were located at equal distances from each Other (no more than 3 mm), and the axis was in the sagittal plane. In this position, a pencil is put at risk on the receiving sleeve and cup of the knee knot against one of the screws 6 of the proximal and distal rings, then the screws are released and the rings are installed so that the hole of the conductor sleeve 13 is against the risks. This position is fixed with screws, holes are drilled through conductor sleeves into the receiving sleeve and the cup of the knee knot, into which the screws are then screwed. When fitting a prosthesis, a search is carried out for the spatial location of the receiving sleeve, which is typical for this patient, after which, without removing the adjustment device, the receiving sleeve is welded to the knee head cup at three four points. The device is then removed and the prosthesis is again tested during trial walking. Thereafter, the connecting portion is finally welded. In the all-wood prosthesis, the device is used similarly with some features of fixing the device and final fixing the receiving sleeve. For reliable fixation of the device, the screws 6 are wrapped in pre-mounted washers with teeth (not shown). After adjustment between connecting ends

: The receiving sleeve and knee assembly usually forms a shell, which, in accessible places, is filled with wooden pads on glue. The device is removed only after the adhesive has hardened, and the final connection of the receiving sleeve with the knee is made with the help of keys. Putties and wrapping around this area with a double layer of the web-, on nitrolac. Alternatively, you can apply a seal of the shell between the receiving sleeve and the rut node with cotton wool impregnated with polyester resin.

An adjustment device for lower limb prostheses, containing 10 basic planes with longitudinal and arcuate grooves and a mechanism of linear and angular mixing in three planes, retaining screws and fastening elements, about which I in order to improve the quality of prosthetics at the stump of the tibia or hip of any length, increase stability when walking, reduce trauma to the stump, the basic planes in it are made in the form of two rings, one of which is detachable, ugoobraznymi grooves forming with locking screws rotating mechanism hydrochloric horizontal plane, and the mechanism of the linear and corner lauryl mixings in the frontal and SYgittalnoy SH1OSKOST5SH formed as a soe-. screw fasteners connecting both rings and consisting of screws located in the longitudinal grooves of one ring having spherical ends, and sliders located in the longitudinal grooves of the other ring.
