LAPAROSCOPIC SURGERY
Operations in the abdomen are performed through small incisions (usually 0.5–1.5 cm).
Makes use of images displayed on TV monitors to magnify the surgical elements.
Reduced pain & hemorrhaging.
Shorter recovery time.
Reduced exposure of internal organs to possible external contaminants
Limitations of Standard Endoscope
Paradigm of pushing long sticks into small openings
Narrow angle imaging
Limited workspace.
Assistants needed to control the camera.
Counter intuitive motion
MARVEL System(Miniature Anchored Robotic Videoscope for Expedited Laparoscopy
What we aim to overcome through MARVEL?
Cable-free platform
Better visualisation
Frees a port in multiport access trocar
Greater dexterity for surgeons
Elimination of assistant to control scope
EXPERIMENTAL EVALUATION
Conducted on a porcine animal
To test illumination, image quality, communication, wireless control
Power dissipation
Comparison with in vivo and external measurement
30db difference in signal strength
Central frequency is shifted
FUTURE WORK
Electronics component with low temperature coefficient
Integrate motion detection and image stabilization
CM powered by internal battery
Wireless transmission of HD video
Illumination system with blue and green light
CONCLUSION
Intended to advance MIS in robotic videoscopes
Wireless actuator control
Wireless and cable free videoscope
Wireless illumination control
Enhanced view inside abdominal cavity
Wireless HMI
Software simulation and system characterization
