The Development and Effectiveness of a Burst Pressure Measurement Tool for Ultrasound Coagulation of Blood Vessels
With the widespread application of ultrasound scalpels in the biomedical field,the burst pressure measurement technology for ultrasound coagulation of blood vessels was mainly used to evaluate the closure ability of ultrasound surgical scalpels on arterial and venous vessels,laying the foundation for its clinical use and research.In this study,a automatic blasting pressure tooling(measuring range:0-3040 mmHg)was designed,and the intelligent operating system was added to this tooling on the basis of traditional tooling,which improved the accuracy of data capture.The experimental results showed that in the same blood vessel diameter bursting pressure test,the difference between the test values of the automatic burst pressure tooling and the traditional burst pressure tooling was±90 kPa,which was not more than 8.1％of the traditional bursting pressure tooling test value;In the testing for same test tooling with different blood vessel diameters,the automatic burst pressure test tooling tested the burst pressure values of blood vessels with different diameters,and the error was smaller than that of traditional burst pressure tooling.Therefore,automatic burst pressure test tooling have high feasibility in replacing traditional burst pressure tooling.
