| 摘 要: 本文基于自制的射频能量平台，开发了一种管腔组织快速闭合算法，可以达到对管腔组织快速闭合的目 的，探究不同功率对闭合效果的影响。在实验中，选取猪小肠作为实验对象，实验过程中改变不同的功率，实验完成 后通过爆破压和热损伤测试，来评估快速闭合算法下不同功率对猪小肠的闭合效果影响。结果表明：当功率设置分别 为50W、100W、150W时，焊接口的闭合强度两两之间有显著性差异，并且在100W功率下的闭合强度较大，爆破压最 大能达到(86.280±17.264)mmHg，热损伤为(0.327±0.032)cm；当射频输出功率大小为50W时热损伤范围最小，为 (0.2674±0.03727)cm。本文研究表明，在对管腔组织闭合的时候，应该选择适中的射频输出功率，才能在保证管腔组 织吻合口具有较大的爆破压同时，又能将热损伤保持在较小范围内。 |

| Abstract: Based on the self-made RF energy platform,this paper develops a fast closure algorithm for lumen tissue,which can achieve the purpose of rapid closure of the lumen tissue and explore the effects of different powers on the closure effects.In the experiment,the small intestine of a pig is selected as the experimental object,and different powers applied during the experiment.After the experiment is completed,the effects of different powers on the closure of the small intestine of the pig are evaluated by means of the burst pressure and thermal damage test.The results show that when the powers are set at 50W,100W and 150W respectively,there is a significant difference between the closing strength of the welded joints,in which the closing strength at 100W is the largest with the bursting pressure of up to (86.280±17.264) mmHg and the thermal damage of (0.327±0.032) cm; when the RF output power is 50W,the thermal damage range is the smallest,which is (0.2674±0.03727) cm.The research in this paper shows that when the lumen tissue is closed,the moderate RF output power should be selected to ensure that the anastomosis of the lumen tissue has a large burst pressure while keeping the thermal damage within a small range. |
