Embodiment Construction

[0042] Fig. 1 illustrates an apparatus 1 for measuring elasticity of a human or animal organ according to a first method of an embodiment of the present invention.

[0043] Said measuring device 1 is used in particular to measure the elasticity of the human or animal organs located behind the ribs 2 of said human or animal.

[0044] The measuring instrument 1 described has a housing 3 in which an electric actuator (not shown) is housed. A mobile ultrasound transducer 4 is mounted at the end of the actuator, a part of the distal end 5 extending outside the body 3 of said measuring instrument 1 . The measuring instrument 1 is also connected to an energy source via a wired connection 6 .

[0045] Since the purpose of the present invention is to improve an existing measuring instrument (the measuring instrument described in patent application WO2004 / 016176), its structure will not be described in more detail here. For the manufacture of said measuring instrument 1 and for an und...

Abstract

The invention relates to an instrument (1) for measuring the elasticity of a human or animal organ located behind the ribs (2). The inventive instrument is of the type that consists of a casing (3) comprising an actuator, the end of which is equipped with a transducer (4) that is actuated in order to measure the elasticity of the organ. The invention is characterised in that the measuring instrument (1) also comprises a means (7) for centring the transducer (4) between the ribs (2).

Description

technical field [0001] The present invention relates to the field of measuring soft tissue viscoelasticity. [0002] More specifically, the present invention relates to an instrument for measuring the elasticity of human or animal organs located behind the ribs of a human or animal. [0003] In particular, but not exclusively, the instrument is used to measure the elasticity of the liver of a human or animal, which measurement has the advantage that the elasticity is related to the amount of fibrosis present in the liver. Indeed, chronic hepatitis caused by alcohol, viruses, or other causes produces a fibrotic effect that needs to be determined in order to choose the best time to treat the disease. Background technique [0004] The prior art already contains such measuring instruments. [0005] In fact, in the previous international patent application WO2004 / 016176 filed by the applicant of the present application, a device for measuring the elasticity of human or animal o...
