Title
(EN) SPINOUS METAL PARTICLE
(FR) PARTICULE MÉTALLIQUE ÉPINEUSE
(ZH) 棘状金属颗粒体
Abstract
(EN)
An spinous metal particle(1), has spherical, cylindrical, polyhedral shaped outer profile which has sea urch in like or dendritic spinous structure and whose size is of about 2 to 15mm. When used, doctors can mix spinous metal particle having suitable quantity, size and shape with autologous or allogenetic broken bone particle and bone cement(3) and stir the mixture to make filler, then fill the defected site of bone with pressure to obtain the initial stability of the filler. In the recovery time after operation, the surrounding bone can be integratedly fused with the bone cement(3) and broken bone particle around the spinous metal particle(1) to form a support structure which has relative stability and biological activity, and the support structure can stimulate the flow of blood around the bone to promote the reparation of defected cartilage.
(FR)
La présente invention concerne une particule métallique épineuse (1), qui possède un profil externe polyédrique cylindrique sphérique ayant une structure épineuse dendritique ou en forme d'oursin, et dont la taille va d'environ 2 à 15 mm. Lors de son utilisation, les médecins peuvent mélanger une particule métallique épineuse, présentant une quantité, une taille et une forme adaptées, avec des particules autologues ou allogènes d'os fracturé et du ciment osseux (3), et remuer le mélange pour former une charge, puis remplir le site osseux atteint sous pression afin d'obtenir la stabilité initiale de la charge. Durant le temps de récupération après l'opération, l'os environnant peut être intégré par fusion au ciment osseux (3) et aux particules d'os fracturé autour de la particule métallique épineuse (1), afin de former une structure de support qui présente une activité biologique et une stabilité relative. La structure de support peut stimuler le débit sanguin autour de l'os pour favoriser la réparation du cartilage défectueux.
(ZH)
一种棘状金属颗粒体(1),其外部轮廓为球形、圆柱形、多面体形,具有类似海胆状或树枝状的棘突结构(2),其外部轮廓尺寸为2-15mm,使用时由医生根据需要选择适当数量、大小和形状的棘状金属颗粒体(1)与患者自体或异体碎骨颗粒及骨泥(3)混合搅泮成混合填充物,装填于骨缺损处加压捣实以获得填充体的初始稳定,术后恢复期时周围的骨质与棘状金属颗粒体(1)周围的骨泥(3)、碎骨颗粒融合生长成一体后即可形成一相对稳定并具有生物活性的支撑结构,同时这种支撑结构还可造成对周围血运的刺激以促进受损软骨的修复。
