一款超声凝闭血管爆破压测量工装的研发及效果

The Development and Effectiveness of a Burst Pressure Measurement Tool for Ultrasound Coagulation of Blood Vessels

超声手术刀在生物医学领域中应用广泛。超声凝闭血管的爆破压测量技术主要用于评估超声手术刀对动脉、静脉血管的闭合能力,为其在临床使用与研究奠定基础。该研究设计了一款自动化爆破压工装[测量范围:0~3040 mmHg(1 mmHg=0.133 kPa)],此工装在传统工装的基础上加入了智能化操作系统,提高了捕捉数据的重复性。实验结果表明,在同一血管直径的爆破压测试中,自动化爆破压测量工装与传统爆破压测量工装的测试值相差±90 mmHg,不超过传统爆破压测量工装测试值的8.1%;在同一血管类型、不同血管直径的测试中,自动化爆破压测量工装测试不同直径血管爆破压值的数值波动均小于传统爆破压测量工装。与传统爆破压测量工装相比,该研究设计的工装提升了自动化水平,确保了加压速度的一致性,提升了测量重复性,因此,自动化爆破压测量工装替代传统爆破压测量工装具有较高的可行性。

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.
