Title
(EN) TESTER FOR MICROMECHANICAL PROPERTIES OF BIOLOGICAL SOFT TISSUE
(FR) TESTEUR DE PROPRIÉTÉS MICROMÉCANIQUES DE TISSU MOU BIOLOGIQUE

Abstract
(EN) A tester for micromechanical properties of a biological soft tissue, comprising: a support, the support being provided thereon with a sample test platform (21), a pressure test head (22) facing the sample test platform (21) and a drive mechanism driving the pressure test head (22) to move towards/away from the sample test platform (21); a miniature force testing assembly, the miniature force testing assembly comprising a first conduit (31), a first piston (32) actively connected to the first conduit (31) and supporting the sample test platform (21), a second conduit (33), a second piston (34) actively connected to the second conduit (33), a pressure-amplifying platform (35) connected to the second piston (34), and a force sensor (36) for testing the force of the pressure-amplifying platform (35), the first conduit (31) and the second conduit (33) being connected by means of a hose, and the cross-sectional area of the sample test platform (21) being smaller than the cross-sectional area of the pressure-amplifying platform (35). A micro force is amplified using the principle of hydraulic amplification, and a micro displacement is amplified using the principle of lever amplification so as to test the micro force and the micro deformation of a biological soft tissue.
(FR) L'invention concerne un testeur de propriétés micromécaniques d'un tissu mou biologique, comprenant : un support dont le dessus est pourvu d'une plateforme de test d'échantillon (21), une tête d'essai de pression (22) faisant face à la plateforme de test d'échantillon (21) et un mécanisme d'entraînement entraînant la tête de test de pression (22) pour se rapprocher/s'éloigner de la plateforme de test d'échantillon (21); un ensemble de test de force miniature comprenant un premier conduit (31), un premier piston (32) relié activement au premier conduit (31) et soutenant la plateforme de test d'échantillon (21), un deuxième conduit (33), un deuxième piston (34) relié activement au deuxième conduit (33), une plateforme d'amplification de pression (35) reliée au deuxième piston (34), et un capteur de force (36) destiné à tester la force de la plateforme d'amplification de pression (35), le premier conduit (31) et le second conduit (33) étant reliés au moyen d'un tuyau souple, et la zone de section transversale de la plateforme de test d'échantillon (21) étant inférieure à la surface de section transversale de la plateforme d'amplification de pression (35). Une micro-force est amplifiée selon le principe d'amplification hydraulique, et un micro-déplacement est amplifié selon le principe d'amplification par levier de manière à tester la micro-force et la micro-déformation d'un tissu mou biologique.
(ZH) 一种生物软组织微观力学特性测试仪,包括支座,支座上设有样本测试台(21)、朝向样本测试台(21)的压力测试头(22)以及驱动压力测试头(22)朝向/背向样本测试台(21)移动的驱动机构;微型力测试组件,微型力测试组件包括第一导管(31)、与第一导管(31)活动连接且支撑样本测试台(21)的第一活塞(32)、第二导管(33)、与第二导管(33)活动连接的第二活塞(34)、与第二活塞(34)连接的放大压力台(35)及对放大压力台(35)进行受力测试的力传感器(36),第一导管(31)与第二导管(33)通过软管连通,样本测试台(21)的截面积小于放大压力台(35)的截面积。采用液压放大原理对微小力进行放大,采用杠杆放大原理对微位移进行放大,从而对生物软组织的微小型力与微小变形进行测试。
