Problems solved by technology

[0004] Due to the difficulty of measuring the mechanical properties of soft tissue, the Young's modulus values ​​of soft tissue reported in different literatures even differ by 2 or 3 orders of magnitude, and the most common difference is about 10 times. These experimental results lack real in vivo measurement data for testing And verification

Abstract

The invention relates to a detection device, in particular to a human body mandibular triangular area force application device in a nuclear magnetic environment. The device comprises a lower jaw supporting frame, an angle-adjustable screw-in force application rod, a resistance-type pressure sensor, a pressure head, a middle connecting body, an upper sliding block and a lower sliding block. The device provided by the invention can be used in an electromagnetic environment, and does not affect the distribution of an original electromagnetic field. The device can be worn and fixed on the head and neck, the size of the device can be accommodated in a nuclear magnetic resonance spectrometer cabin, and a mechanical precession device is adopted to apply an adjustable load. Therefore, a conventional load applying mode of forbidden power supply driving in the nuclear magnetic scanner is avoided.

Description

technical field [0001] The invention relates to a detection device, in particular to a force applying device for the mandibular triangle area of ​​a human body under a nuclear magnetic environment. Background technique [0002] Understanding the in vivo mechanical properties of human soft tissue is of great significance to the study of human physiological functions, but measuring the mechanical parameters of human soft tissue in vivo is always a huge challenge. The traditional stretching method is generally suitable for measuring the mechanical properties of isolated tissues. At present, there are mainly indentation methods for in vivo measurement, which can be used to measure the mechanical properties of skin tissue in vivo, that is, it is suitable for measuring the mechanical properties of superficial human tissue under small deformation. Although ultrasonic elastography can be used to measure the mechanical parameters of deep soft tissues in vivo, the repeatability of ul...
