Problems solved by technology

Although this system overcomes the arbitrariness of manual loading, it still cannot overcome the limitations of the A-super system
In 2000, Italy’s Scalari, G et al. developed a non-invasive soft tissue mechanical property testing microsystem. Through a vacuum chamber pasted on the surface of the human body, the surface of the soft tissue is lightly sucked to deform it. The pressure of the vacuum chamber can be obtained by a pressure measuring instrument. Tissue deformation can be obtained by a laser measuring instrument placed above the vacuum chamber, this device is only suitable for analyzing the biomechanical properties of superficial skin tissue

Embodiment Construction

[0029] 1. System composition

[0030] The structure and working principle of the present invention—the acquisition system of dynamic load response parameters of soft tissues in the body are shown in Fig. 1 ,

[0031] The acquisition system consists of five parts: host computer, ultrasonic-mechanical composite probe, stepper motor dynamic loading device, B / M type ultrasonic diagnostic instrument and universal mobile positioning workbench. The host is composed of PC, data acquisition card and video acquisition card. While controlling the dynamic loading, it can track and collect the B / M two-dimensional image signal from the ultrasonic diagnostic instrument and the mechanical signal from the composite probe in real time, and display it on the screen and storage.

[0032] Before the system performs data collection work, firstly, adjust the universal mobile positioning workbench so that the ultrasonic-mechanical composite probe is accurately aligned with the soft tissue of the mea...

Abstract

A dynamic load response parameters acquiring system for the on-body soft tissue is composed of a universal moxing-locating bench, a composite ultrasonic-mechanical probe consisting of B / M-type linear-array ultrasonic probe and mechancial probe, and a loading / unloading system with step motor. They are respectively connected to master computer and B / M-type ultrasonic diagnosing instrument.

Description

technical field [0001] The invention belongs to medical auxiliary equipment, in particular to a system for collecting dynamic load response parameters of in-body soft tissue. Background technique [0002] Non-invasive, objective, quantitative, in vivo evaluation of the biomechanical properties of human soft tissue is of great significance for the diagnosis and research of clinical diseases, the evaluation of curative effect, and even the development of rehabilitation aids. Such as: early identification of pressure sore sensitive soft tissue, changes in characteristics of cervical soft tissue in patients with cervical spondylosis before and after intervention such as traction and physical therapy, using viscoelastic parameters measured in vivo to optimize the design of anti-pressure by finite element analysis Sore products and prosthetic sockets, changes in the characteristics of the plantar soft tissue of diabetics, etc. For a long time, the completion of the above work mai...
