PCT No. PCT/EE97/00001 Sec. 371 Date Sep. 24, 1998 Sec. 102(e) Date Sep. 24, 1998 PCT Filed Mar. 21, 1997 PCT Pub. No. WO97/35521 PCT Pub. Date Oct. 2, 1997The method and device for recording mechanical oscillations in soft biological tissues consists of the following: biological tissue is mechanically influenced by means of the testing end (6) of the device and its mechanical responses are subsequently recorded as a graph representing the evoked oscillations. Prior to that, an inflexible plane means (12) is fastened onto the biological tissue in order to designate the area under investigation and connect the testing end with the tissue, causing no harm to the latter. After that the testing end will be inflexibly connected with the inflexible plane means for the time period it takes to influence the tissue mechanically and record its mechanical response. The device consists of a frame (1), a pivotable double-armed lever (2), an electromechanical transducer (3), a shutter (4), a grip, an electromechanical pickup (5), a testing end (6), a pivot (7), a testing end driver (8, 9), a control switch (11), a control panel (10), and an inflexible plane means (12) for marking on the tissue the area under investigation and for connecting the testing end with the tissue permanently and inflexibly, causing no harm to the biological tissue. The length of the testing end (6) is adjustable by means of, for instance, a bayonet joint. |
