Description

Ultrasound Probe Assembly

technical field

The utility model belongs to the technical field of ultrasonic equipment, in particular to an ultrasonic probe assembly.

Background technique

Like ordinary sound, ultrasound can propagate in a certain direction and can penetrate objects. If it encounters an obstacle, it will generate an echo. Different obstacles will generate different echoes. People collect this echo through instruments. And displayed on the screen, can be used to understand the internal structure of the object.

Ultrasound examination is a non-invasive examination method commonly used in clinical practice. It is painless, non-invasive, and non-radioactive to the subject. It has obvious advantages in the precise positioning and guidance of some internal tissues and structures in the body, and it has been applied in more and more fields. including the field of anesthesiology.

In clinical work, the anesthesiologist first uses an ultrasound probe to observe the target site to understand the tissue structure of the site, mainly the shape of blood vessels and nerves, and then performs vascular puncture or nerve block under the guidance of ultrasound. However, in actual operation, it is difficult to grasp the essentials of operation in the ultrasound plane, and it is difficult for inexperienced physicians to ensure that the puncture needle is always in the ultrasound plane, making it difficult to guarantee the position and path of needle insertion.

In addition, once the puncture needle is inserted, it is constrained by human skin tissue, fat tissue, and muscle tissue, and the needle body can only be adjusted in depth. If the position of the puncture needle is misplaced, it is difficult to adjust the needle body outside the body to change the needle insertion route. The only way is to pull the needle head under the skin first, then adjust the position and insert the needle again. Repeating this many times will inevitably damage the patient's body, increase the pain of the patient, prolong the operation time, and also increase the chance of the patient's infection.
