Interactive Augmented Reality for Robot-Assisted Surgery
Maria Paola Forte, Katherine J Kuchenbecker, PhD. Max Planck Institute for Intelligent SystemsObjective: Most robotic surgery applications of augmented reality (AR) focus on bringing pre-operative images (e.g., MRI) into the surgeon’s intra-operative workspace. We are exploring alternative uses and interaction methods of AR. In collaboration with laparoscopic surgeons, we identified five possible AR tool categories:… Continue Reading
Laparoscopic Surgery Trainer for Low and Middle-Income Countries: A Pilot Study in Rural Ethiopia
Jonathan Jou. University of Illinois College of MedicineObjective: Laparoscopic surgeries allow for shorter hospitalizations, earlier mobility, and decreased surgical site infections, advantages well-published in the literature and crucial in rural, agrarian communities. Surgeons practicing in low and middle-income countries (LMIC), where patients stand to benefit from these techniques the most, are often faced with difficult… Continue Reading

MeshLock Device Simple Suture Mesh Fixation for Laparoscopic Hernia Repair
Michael Kia. Mclaren Regional Medical CenterEvery year approximately 175,000 laparoscopic ventral hernia procedures are performed. There are significant benefits including shorter length of stay and significantly lower infection rates, significant post-operative pain is still an issue with the procedure. Current fixation methods include tacks, absorbable and non-absorbable, along with transfascial fixation. Typically at least… Continue Reading
Modeling and Simulation of Stress Distribution on Deformable Tissue for a Magnetic Actuated Laparoscopic Camera
Ning Li, Jindong Tan, PhD. The University of TennesseeBackground and Objective: Fully insertable laparoscopic cameras, compared to conventional trocar-based laparoscopes, feature more locomotive flexibility in a larger workspace and thus represent a promising trending of laparoscopic imaging devices. These cameras, typically anchored against the interior abdominal wall and manipulated through magnetic coupling, although have shown their… Continue Reading
Modified Endoloop
