Swords in Medicine: Ultrasound in Surgery

Continuous advancements in medical technology provide surgeons with additional tools and methods to improve surgical procedures and outcomes. Among them, ultrasound, as a non-invasive medical imaging technology, is more and more widely used in surgery. The high-frequency oscillation and imaging capabilities of ultrasound make it a sharp sword in medicine and play an important role in surgery.

1. Ultrasonic principle and imaging

Ultrasound generates images by sending high-frequency sound waves into human tissue and receiving reflected signals. It uses the difference in the propagation speed of sound waves and the different acoustic impedance of tissues to clearly display the internal structure of the human body. Through ultrasound imaging, doctors can observe and evaluate the patient's organs, blood vessels and lesions, and provide important references for surgery.

2. Ultrasound Navigation and Localization During Surgery

Navigation and positioning during surgery are critical. Ultrasound can provide real-time images to help doctors accurately locate and navigate surgical procedures. For example, in tumor resection surgery, ultrasound can help doctors determine the exact location and boundaries of a tumor so that it can be removed more precisely. In addition, ultrasound can also assist in the positioning and introduction of instruments during surgery, improving the accuracy and safety of surgical operations.

3. Ultrasound Fragmentation and Attraction During Surgery

In addition to its use for imaging and navigation, ultrasound can also be used for fragmentation and suction during surgery. For example, in urinary stone lithotripsy, ultrasound can shatter the stones by vibrating and crushing them, making them easier to attract out of the body. This non-invasive surgical approach reduces surgical risk and recovery time.

4. Application of Ultrasound in Minimally Invasive Surgery

With the development of minimally invasive surgical techniques, the application of ultrasound has also been further expanded. Ultrasound can be used as a visualization tool in minimally invasive surgery to help doctors perform endoscopic operations. At the same time, ultrasound can also be used for blood flow detection, blood vessel positioning and tissue evaluation during minimally invasive surgery, improving surgical safety and effectiveness.

Ultrasound plays an important role in surgery as a non-invasive medical imaging technique. Its high-frequency oscillation and imaging capabilities make it a sharp sword in medicine, providing accurate navigation and positioning for doctors, enabling minimally invasive surgery and comminution of lesions, and reducing surgical risks. With the continuous advancement of technology, ultrasound will continue to expand its application range, and bring more convenience and benefits to surgeons, and bring safer and more accurate surgical treatments to patients.
