Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical equipment, and in particular relates to a hand and foot ultrasonic mold sleeve component. Background Art
[0002] High-frequency ultrasound examination has the advantages of no radiation damage, non-invasive, low-cost, repeatable examination in a short period of time, real-time imaging and high soft tissue resolution. At the same time, since ultrasound examination can be performed dynamically and in real time under various patient movements and postures, and bilateral comparison can be performed, these characteristics of ultrasound examination have been continuously recognized and valued in clinical practice. However, in some diseases involving small joints, especially interphalangeal joint ultrasound examination, it is often difficult to control the distance between the probe and the skin and the degree of coupling. Especially for the diagnosis of some early lesions or hemodynamics and the monitoring of disease changes, the examination effect is often unsatisfactory, and even misdiagnosis occurs. Due to the limitation of the probe shape, the ultrasound probe is still limited to hand-held type. In clinical use, it is found that the doctor holds the ultrasound probe with one hand, that is, the traditional interphalangeal joint examination relies on the examiner to control the direction and strength of the probe. There is a lack of effective fulcrum, and it is difficult to achieve good control of the distance between the probe and the skin and the degree of coupling. The image quality is poor, and it affects the hemodynamic judgment. It is also a physical consumption and fatigue injury for the examiner.
