Accurate positioning and monitoring are crucial in neurosurgery. With the development of medical technology, ultrasonic scanners have become increasingly widely used in neurosurgery, becoming an indispensable auxiliary tool. This article will explore the application of ultrasound scanners in guiding and monitoring neurosurgery operations.

1、 Principles and advantages of ultrasonic scanners

Ultrasonic scanner is a device that uses the echo of ultrasound to detect and image human tissue. It generates images by emitting ultrasonic pulses and then receiving and analyzing the reflected sound waves. Compared to other imaging technologies such as CT and MRI, ultrasound has the following advantages:

1. No radiation: Ultrasound is radiation free and harmless to patients and medical staff.

2. Real time imaging: Ultrasound can provide real-time imaging, enabling doctors to dynamically monitor and guide the surgical process.

3. Low cost: Compared to other imaging technologies, the cost of ultrasound equipment is relatively low.

2、 The guiding role of ultrasound scanner in neurosurgery surgery

1. Preoperative planning: Ultrasound scanners can help doctors determine the surgical path and target area before surgery. Doctors can accurately measure the location and size of lesions through real-time imaging through ultrasound scanning, providing reference for the formulation of surgical plans.

2. Intraoperative positioning: Ultrasound scanners can guide doctors' surgical instrument positioning in real-time during surgery. Doctors can guide the accurate positioning and operation of surgical instruments through the images of ultrasound scanners, ensuring the accuracy and safety of the surgery.

3. Vascular localization: Neurosurgery surgery requires avoiding important blood vessels, and ultrasound scanners can help doctors accurately identify and locate blood vessels during surgery, avoiding accidental damage during surgery.

3、 The monitoring role of ultrasound scanner in neurosurgery surgery

1. Lesion monitoring: During the surgical process, ultrasound scanners can monitor changes in the size and location of lesions in real-time. Doctors can make timely adjustments and decisions based on the results of ultrasound scans to improve the success rate and safety of surgery.

2. Neuromonitoring: Ultrasound scanners can help doctors monitor changes in neural function in real-time. For example, in brain tumor surgery, doctors can monitor the blood flow and perfusion status of brain tissue through ultrasound scanner images, as well as changes in nerve conduction function, to avoid nerve damage.

3. Liquid monitoring: Ultrasound scanners can help doctors monitor the condition of liquid in the body cavity in real-time. For example, in ventriculocentesis, doctors can monitor the discharge of fluid from the ventricles of the brain using ultrasound scanner images to avoid problems caused by fluid accumulation.

4、 The limitations and development direction of ultrasonic scanners

Despite the widespread application of ultrasound scanners in neurosurgery, there are still some limitations. For example, the image resolution is relatively low and small details cannot be observed; The imaging effect is poor for special tissues such as bones and gases. In addition, the operator's proficiency in ultrasonic scanners can also affect their application effectiveness.

In the future, with the continuous development and improvement of technology, the application of ultrasound scanners in neurosurgery surgery will be further expanded. For example, the imaging resolution of ultrasound will be improved, allowing for clearer display of tissue and vascular details; By applying artificial intelligence and machine learning algorithms, ultrasonic scanners can perform automatic analysis and recognition, providing more accurate detection results.

In summary, ultrasound scanners play an important guiding and monitoring role in neurosurgery surgery. It can help doctors locate, monitor lesions, and protect important structures in real-time during the surgical process, improving the success rate and safety of surgery. With the development of technology, the application of ultrasound scanners will continue to improve, bringing more convenience and breakthroughs to neurosurgery surgery.
