At present, major brands in the field of ultrasound abroad include "GPS", and domestic ultrasound has also risen in recent years. Kaikai Medical, established in 2002, has entered the top 10 global ultrasound companies. Thanks to its advanced probe technology, it is able to stand out in the fiercely competitive ultrasound field. Kaikai is renowned for its high technological content, complete variety, and excellent quality in the field of independent research and manufacturing of probes. This is also the confidence that Kaikai can compete with domestic and foreign peers in the field of ultrasound. Today, this article takes Kaikai as an example to take an inventory of ultrasound probes.
Different probes correspond to different clinical fields, and different probe frequencies are also applied to different human tissues. The attenuation of ultrasound in the human body is related to the probe frequency. The higher the probe frequency, the weaker the penetration force and the higher the resolution, while the lower the probe frequency, the stronger the penetration force and the lower the resolution. Therefore, high-frequency probes should be used when examining superficial organs, while low-frequency probes with strong penetration should be used when examining deep organs.

Mark point:
Mark point: Each probe has a mark point, which is used for positioning direction. One side of the mark point always corresponds to the side of the image S point (indicated by the image arrow).

Usage of ultrasound probe:
(1) Pen holding style: Similar to holding a brush, held with the thumb, index finger, and middle finger.
The main basic movements are completed through finger joint movements, with the ulnar or little finger of the palm touching the patient's chest as the fulcrum to maintain image stability.
(2) Grip style: commonly used for obtaining the lower section of the xiphoid process.

Techniques and techniques for obtaining ultrasound planes
(1) Sliding: The entire ultrasound probe plane is tightly attached to the skin of the tested area, sliding in a certain direction.
(2) Shake: The entire ultrasound probe plane is closely attached to the skin of the test area, and the contact point between the ultrasound probe and the chest wall is used as the fulcrum. The ultrasound probe is swung left and right to observe the entire section.
(3) Tilt: The entire ultrasound probe plane is closely attached to the skin of the tested area, with the contact point between the ultrasound probe and the chest wall as the fulcrum. Tilt the ultrasound probe back and forth to observe different sections.
(4) Rotation: The entire plane of the ultrasound probe is tightly attached to the skin of the tested area, with the contact point between the ultrasound probe and the chest wall as the fulcrum. The ultrasound probe rotates clockwise or counterclockwise at a certain angle along its own central axis.
Kind reminder:
In order to obtain an ideal image, in addition to paying attention to instrument adjustment, it is also necessary to pay attention to the following basic procedures and techniques:
1. To avoid interference from gas, such as filling liquid in certain hollow organs and deep tissues during detection, such as filling the stomach after drinking water to clear gas in the stomach, making it easier to observe lesions in the stomach or using it as a "translucency window" to observe the pancreas, etc; At the same time, it is necessary to fully apply coupling agent to remove the thin layer of gas between the probe and the skin, reducing the attenuation of sound energy;
2. Utilize certain physiological and anatomical characteristics for observation. For example, on an empty stomach, the gallbladder is filled with bile, making it easier to observe lesions inside the gallbladder; For example, in respiratory coordination, if necessary, Valsalva maneuver can be used to increase the pressure in the lungs and chest, reducing venous reflux and allowing for clear visualization of the hepatic vein and inferior vena cava.
3. Use different sections to continuously scan organs and lesions.
