| dc.description.abstract | The cauterization process is a method for heating a portion of tissue to close the wound and mitigate the bleeding by tissue coagulation prior to the tissue’s cutting. In this study, a new concept of Thermomechanical Cautery was proposed through the idea of combining the thermal element (Kanthal A-1 Wire) and mechanical element (DC Motor) as one complete system. Thermal cautery and Ultrasonic cautery are commercially used for the surgery for tissue cutting and hemostasis. The lateral thermal spread across these 3 cautery devices was compared. The development of the Thermomechanical Cautery was designed in SolidWorks, followed by the Finite Element Analysis in ANSYS Workbench. A thermal element was first tested on the chicken skin sample to determine its minimum baseline for cauterization and cutting in a static condition. Once the fabrication of the Thermomechanical Cautery is done, a testing with the complete system was carried out in a dynamic manner due to the presence of the mechanical element. By using light microscopy, the image of the dissection site was captured, and the image will undergo an image processing technique in MATLAB to measure its lateral thermal spread. The minimum baseline for cauterization and dissection is 180.1°C with power supply of 10.96 W for the thermal element and 0.69 W for the mechanical element. It took about 30 seconds for a 10 mm cut length. After the dissection, the mean of the thermal spread on one side for Themomechanical Cautery, existing Thermal Cautery and Ultrasonic Cautery were 0.712 mm, 1.436 mm and 1 mm, respectively. Thus, the Thermomechanical Cautery recorded the lesser degree of thermal spread in tissue. | |
