چکیده
فناوری‌های جراحی نوین با هدف افزایش راحتی و قابلیت کنترل عملیات حین عمل و کاهش صدمات حاصل از عمل جراحی در حال توسعه می‌باشند. ابزار جراحی لاپاراسکوپی فراصوتی یک فناوری نوین جهت کاهش صدمات حاصل از عمل جراحی می‌باشد. دستیابی به پارامترهای ورودی مناسب در ابزار جراحی فراصوتی، باعث افزایش قابلیت اطمینان عمل و کاهش صدمات حاصل می‌شود. در پژوهش حاضر با ثابت نگه داشتن نیروی اعمالی بر بافت رگ، اثر تغییر معیار توان و زمان اعمال ارتعاشات فراصوتی و معادل آن انرژی ورودی به رگ در عمل جراحی، بر استحکام مکانیکی اتصال بافت و اثرات حرارتی عمل مورد ارزیابی قرار گرفته است. بدین منظور قابلیت تحمل فشار خون در سرخرگ کاروتید مشترک گوسفند و آسیب حرارتی (سوختگی) ناحیه تحت عمل به ترتیب توسط آزمون فشار و بررسی تصویر اثر حرارتی مورد بررسی قرار گرفته است. نتایج پژوهش نشان داده است که در یک زمان مشخص، یک توان بهینه برای دستیابی به بیشترین قابلیت تحمل فشار بدست آمده است. اما با ثابت نگه داشتن توان، معیار زمان تاثیر یکسانی بر قابلیت تحمل فشار رگ نداشته است. بیشترین مقدار تحمل فشار رگ برابر با 1100 میلیمتر جیوه در توان 44 وات و زمان 10 ثانیه در نیروی 10 نیوتن بدست آمد. نتایج نشان داد با افزایش انرژی ورودی، میزان آسیب حرارتی به بافت اطراف نیز افزایش می‌‌یابد.

چکیده English

New surgical technologies are continuously being developed to enhance control during operations and mitigate injuries resulting from surgical procedures. One such advancement is the ultrasonic laparoscopic surgical tool known as the ultrasonic scalpel, which is designed to minimize surgery-related injuries when used alongside conventional tools. Establishing optimal input parameters for this ultrasonic instrument not only enhances operational reliability but also decreases the risk of resultant injuries. Ongoing research investigates the impact of varying power and duration of ultrasonic vibrations, along with the equivalent energy input into the blood vessel during surgery, on tissue mechanical characteristics and thermal effects. This study assesses the ability of sheep carotid artery tissues to withstand blood pressure within the vessel and examines thermal damage through pressure testing and optical imaging. Findings indicate that maintaining constant time at specific power yields maximum pressure tolerance at optimal power levels. However, varying the time at specific power settings produces different effects. For instance, the highest blood pressure resistance, at 1100 mmHg, was observed at 44 Watt of power over a 10 second duration at 10 newton. Furthermore, results demonstrate that increased energy input correlates with heightened thermal damage to surrounding tissues during the operation.
