La Universidad Técnica Federico Santa María, a través de su Departamento de Electrónica, les invita cordialmente a participar de la charla "Enhancing Surgery Through Proximal Vibro-acoustic Sensing of Tool-Tissue Interactions".
Esta actividad se realizará el 14 de agosto, a las 12:30 hora, en modalidad online.
Minimally invasive surgical procedures, such as laparoscopic and robotic surgery, needle insertions, and catheter or guidewire navigation, present challenges related to navigation and haptic perception. Conventional approaches, including optical or electromagnetic tracking and force or haptic sensors embedded in instruments, can be complex, expensive, and may interfere with the mechanical properties or clinical usability of the tools.
This work explores a sensing methodology based on proximal vibroacoustic measurement to extract information on tool-tissue interactions. When a surgical instrument contacts tissue, mechanical vibrations propagate through the instrument. By placing a vibroacoustic transducer at the proximal end of the tool, outside the patient’s body, these signals can be recorded and processed to provide information on interactions occurring at the distal end. This approach does not require modifications to the instrument’s tip or shaft, allowing it to function as an ext
