The Effects of Ultrasonic Cutting Vibration on Bone Tissue
Description
In this presentation, Nisreen Al-Namnam from the University of Edinburgh details a significant research project involving ultrasonic technology in bone surgery. The primary focus is on how precision is critical in surgical settings, particularly when dealing with delicate bone structures surrounded by important anatomical features. Al-Namnam discusses challenges associated with the use of ultrasonic tools, specifically the heat generated through friction, which can lead to cell damage, particularly affecting osteocytes responsible for bone health.
During the presentation, Al-Namnam describes an in vitro experiment conducted on fresh rat femoral shafts to assess the effects of varying ultrasonic frequencies and displacement amplitudes on bone cutting. The results indicated varying degrees of cell viability and surface damage, highlighting the importance of frequency and amplitude in minimizing surgical impact on surrounding cells.
The findings were validated through histological examinations and confocal microscopy, confirming that using a higher frequency (35 kHz) at a lower displacement amplitude led to significantly less cellular damage compared to other settings. Al-Namnam expresses gratitude for the opportunity to engage with the international research community during a recent trip to North America and acknowledges the collaborative learning experiences it provided.
Overall, this presentation not only showcases promising advancements in surgical technologies but also emphasizes the significance of multidisciplinary research in guiding future innovations.
