Description

Изобретение относитс к медицинской технике , а именно к протезам верхних конечностей .The invention relates to medical technology, namely to upper limb prostheses.
Известен захват, содержащий две бранши, узел разведени и креплени их и упругий элемент дл схвата 1.A gripper is known, comprising two branches, a dilution and fixing unit, and an elastic element for gripper 1.
Однако этот захват имеет ограниченные возможности схвата разнообразных по форме и размерам предметов (в частности, цилиндрических предметов больших диаметров), а также отсутствие замка на крючке, вследствие чего при наклоне переносимый предмет может соскользнуть с крючка. Захват не обеспечивает кулачный схват и возможности изменени взаимного расположени в пространстве плоскостей, соприкасающихс с захватываемым предметом, т. е. способностью к формоприспосабливанию, необходимой дл работь и взаимодействи различными предметами окружающей среды. Дл обеспечени возможности захвата предметов различной геометрической формы и размеров в предлагаемом захвате к протезу одна из бранщ захвата снабжена поворотным механизмом с бесступенчатой фиксацией, например в виде черв чной пары, бранщи имеют криволинейные спиральные боковые поверхности, которые облицованы эластичной пластмассой.However, this grip has limited opportunities for gripping objects of various shapes and sizes (in particular, cylindrical objects of large diameters), as well as the absence of a lock on the hook, as a result of which the portable object may slip off the hook when tilted. The grip does not provide the fist-tong and the possibility of changing the mutual arrangement in space of the planes in contact with the captured object, i.e., the ability to adapt to the shape required for the operation and interaction of various environmental objects. In order to enable the capture of objects of various geometrical shapes and sizes in the proposed grip to the prosthesis, one of the gripping arms is equipped with a swivel mechanism with infinitely fixed fixation, for example, in the form of a worm pair, the jaws have curvilinear spiral side surfaces that are lined with elastic plastic.
На фиг. 1 изображен захват к протезу верхней конечности с частичным разрезом; на фиг. 2 - сечение по А-А на фиг. 1.FIG. 1 shows the grip to the upper limb prosthesis with a partial cut; in fig. 2 is a section along A-A in FIG. one.
Захват состоит из двух сегментов 1 и 2, образующих вместе с осью 3 узел разведени The gripper consists of two segments 1 and 2, forming together with axis 3 a dilution node
и креплени бранш. В подвижном сегменте 1 жестко закреплена бранша 4 и установлена серьга 5 дл раскрыти бранш. Неподвижный сегмент 2 имеет хвостовик 6 дл креплени в протезе. В сегменте 2 установлена бранщаand fastening branches. In the moving segment 1, the branch 4 is rigidly fixed and a link 5 is installed to open the branch. The fixed segment 2 has a shank 6 for mounting in the prosthesis. Segment 2 has a branche
7 с поворотным механизмом с бесступенчатой фиксацией, включающим ось 8 с черв чным колесом 9, наход щимс в зацеплении с черв ком 10, св занным осью II с регулирующим колесом 12. Поворотный механизм бранши 7 установлен в двух направл ющих втулках 13 и 14. Бранща 4 установлена в сегменте 1 посредством втулки 15. На втулках 13 и 15 надет упругий элемент 16. Бранщи 4 и 7 имеют криволинейные спиральные боковые7 with a rotary mechanism with stepless locking, including an axis 8 with a worm gear 9, which is engaged with a screw 10, connected with axis II with an adjusting wheel 12. The rotary mechanism of the branch 7 is installed in two guide bushings 13 and 14. Branche 4 is installed in the segment 1 by means of the sleeve 15. On the sleeves 13 and 15 is put on the elastic element 16. Branschi 4 and 7 have curved spiral lateral
поверхности, которые облицованы эластичной пластмассой.surfaces that are coated with elastic plastic.
Захват работает следующим образом. Дл поворота бранши 7 производ т раскрытие захвата при помощи внещней силы,Capture works as follows. To rotate the branches 7, a gripping opening is performed using external force,
приложенной к серьге 5 (например через т гу протеза, в котором установлен захват). Движением от себ инвалид прокатывает регулирующее колесо 12 по плоскости (стола, стены ), вследствие чего св занный с ним черезattached to the earring 5 (for example, through the tube of the prosthesis in which the grip is installed). Moving from itself, the disabled person rolls the regulating wheel 12 on a plane (table, wall), as a result of which it is connected with it through
