Summary
A novel laparoscopic ultrasound probe (type 8555) enables real-time imaging and color-flow Doppler of intra-abdominal organs. This new technology facilitates detailed examination of the biliary tree, liver, pancreas, and spleen during minimally invasive procedures.
Area of Science:
- Medical Devices
- Surgical Technology
- Diagnostic Imaging
Background:
- Laparoscopic surgery requires specialized instruments for visualization.
- Existing ultrasound probes may have limitations in maneuverability and scope for intra-abdominal imaging.
Purpose of the Study:
- To introduce and evaluate a new ultrasound probe specifically designed for laparoscopic sonography.
- To assess the probe's capability in visualizing key intra-abdominal organs.
Main Methods:
- Development of a new laparoscopic ultrasound probe (type 8555) with specific dimensions and features.
- The probe incorporates a 5-7.5-MHz convex scanner with 90-degree upward and 45-degree downward angulation.
- Utilized real-time sonography and color-flow Doppler capabilities for imaging.
Main Results:
- The probe, measuring 9.5 mm in diameter and 39 cm in length, demonstrated successful application in initial trials.
- Facilitated sonographic examination of the biliary tree.
- Enabled visualization of the liver, pancreas, spleen, and other intra-abdominal organs.
Conclusions:
- The new laparoscopic ultrasound probe (type 8555) is a valuable tool for minimally invasive intra-abdominal diagnostics.
- It enhances the ability to visualize critical organs, improving diagnostic capabilities in laparoscopic surgery.
- Further clinical adoption is warranted to explore its full potential in surgical settings.
