Description
. . . . 1:. . . . one:
; Изобретение относитс к об астн медицинской техники и может быть использовано в травматологии и ортопедии .; This invention relates to medical technology and can be used in traumatology and orthopedics.
: Известен остеостимул тор, содержа щий корпус, источник питани , стабилизатор токи и электроды Cl : An osteostimulator is known, containing a body, a power source, a stabilizer currents and Cl electrodes
. Недостатком да нного остеостимул тора вл етс несоответствие электрического воздействи посто нным токе нормальнсму физиологическому электрогенеэу, в.силу которого потенциалы действи , обусловленшле наличием у кость пьезоэлектрических свойств, распредел ютс по кости, подчин сь апериодическому характеру механических воздействий. Дл имплантируемого остеостимул тора характерно наличие электрохимического источника тока, что предполагает дополнительные меры по обеспечению его герметичности и изол ции. Кроме того , в услови х имплантадаи устройства оказываетс невозможньм контроль параметров стимул даи.. The disadvantage of this osteostimulator is the incompatibility of the direct current with the normal physiological electrogenesis, the strength of which is due to the potentials of the piezoelectric properties that are distributed over the bone, subject to the aperiodic nature of the mechanical effects. The implanted osteostimulator is characterized by the presence of an electrochemical power source, which implies additional measures to ensure its tightness and isolation. In addition, in the conditions of implantation and device, it is impossible to control the parameters of the stimulus.
Целью изобретени вл етс сокращение сроков извлечени .The aim of the invention is to reduce the time of extraction.
Указанна цель достигаетс тем, что в о.стеостимул торе, содержащем корпус с отверсти ми дл его фикса223292This goal is achieved by the fact that in a steostimulator, comprising a housing with openings for fixing it.
цйи, покрытый биоинертным изол ционным материалом, и электроды, расположенные на рабочей поверхности, корпус снабжен стержневыми элемента5 ми из пьезоэлектрического материала, один из торцов которых соединен с электродом.bio-inert insulated material and electrodes located on the working surface, the housing is equipped with rod elements 5 of piezoelectric material, one of the ends of which is connected to the electrode.

В процессе остеосинтеза пластинку закрепл ют на костных отломках, при этом в процессе сращени под действием осевых нагрузок костныеIn the process of osteosynthesis, the plate is fixed on the bone fragments, while in the process of adhesion under the action of axial loads the bone
20 отлсмки испытывают микродеформации, что приводит к радиальным деформаци м пьезоэлектрических стержней и возникновению в результате наличи поперечного пьезоэффекта на торцо5 вых поверхност х разностей потенциалов . Так как величина воздействукдцих усилий выражаетс в виде функции рассто ни от места дефекта, этому функциональному закону подчинено и рас0 пределение потенциалов на стержн х.20 microscopes experience microdeformations, which leads to radial deformations of piezoelectric rods and the appearance of a transverse piezoelectric effect on the end faces of potential differences. Since the magnitude of the impact force is expressed as a function of the distance from the location of the defect, the distribution of potentials on the rods is subject to this functional law.
