Using Digital Twins for Surgical Simulation
The digital twin technology paradigm shift is upon us, and the medical field will never be the same again. A digital twin in the operating room is a real-time virtual model of the patient's anatomy created from imaging data such as MRI, CT, or ultrasound. These models can be used by the surgeons to rehearse the procedures before the actual operation. In robotic surgery, digital twins play a significant role in planning, risk evaluation, and training that occur in a virtual environment closely resembling the patient's actual anatomy. Digital twins differ from existing models in that they do not require recalibration and updates, as they are continually reshaped and refreshed with new data, such as changes in organ or tumor size. With robotic systems, they become a support for surgical guiding decisions; hence, the tool movements are more precise and cause less tissue damage.
A recent online study offered an example of a virtual-reality digital twin simulator for robotic minimally invasive surgery (VRDT-RMIS) launch. This simulator not only demonstrated the significant difference in skill levels between experts and novices but also highlighted its usefulness in training and assessment. The training has become more immersive and realistic with the addition of haptic feedback and visual cues. This approach simultaneously makes the surgeries more accurate and less bloody, especially in cases of the brain, spine, or heart which are complex surgeries. Additionally, digital twins are helping hospitals develop personalized treatment algorithms and enabling continuous monitoring. With the simultaneous development of AI and real-time data integration, digital twins are expected to play a vital role in the future of advanced robotic surgery.
Robotic Endoscopy and Capsule Navigation
Robotic endoscopy and capsule navigation have made significant progress in gastrointestinal diagnostics, providing an alternative that is both less invasive and more accessible for patient psychologists than conventional endoscopy. The tiny, robot-controlled capsules are usually the size of a vitamin pill and can be swallowed to traverse the gastrointestinal tract, producing high-quality images or videos in real-time and sending them to the doctor. Patients do not have to be sedated and can be more compliant with the procedure, as well as less anxious, thanks to the capsule and endoscope, which are less intrusive and thorough, respectively. Modern types have a magnetic control system or micro-motors that enable doctors to remotely direct the capsule to the desired location. Some of the models even possess pH, temperature, and pressure measuring instruments as their additional diagnostic aids.
In a recent study, wireless capsule endoscopy (WCE) was found to be a non-invasive method for examining the intestinal tract, which does not necessitate sedation and reduces the risks associated with traditional endoscopy. WCE is primarily used to detect conditions in the small intestine, such as bleeding, inflammation, tumors, and polyps in hard-to-reach areas. The rapid development of technology for wireless communication, imaging, and robotic control has made the capsule endoscope a likely candidate for increased use as a gastroenterology tool.
