The use of piezoelectric effect to improve instrument quality and patient safety in laparoscopic surgery.

The piezoelectric properties of some natural crystals and polymers can also be used in surgery. For this purpose, a prototype of an endoscopic instrument was constructed with piezoelectric material attached to its working end with the aim of recognizing pulsating blood vessels during laparoscopic surgery. To test the properties of the new instrument in laboratory conditions, simulated blood circulation was used with the possibility of changing pressure and frequency.
