Description
Field of Invention:
The present invention relates to remote real time operative procedures video collaboration for the telestration purposes. More particularly, the present invention relates to real time telestration on operative procedures video for effective mentoring of group of mentees by group of mentors by bringing the experts and the learners together on a virtual platform to provide real time, precise and focused audiovisual feedback complemented with digital markers which can be added as a layer over the real time streaming of operative procedures.
Background of Invention
Procedural Learning in medicine and in operative procedures has been following the traditional ways of since physicians and surgeons still practice some variation of “see one - do one - teach one” methodology. These currently practiced methods have many inherent flaws and most of the complications of a learner happens during and under the learning curve. All seasoned and trainee proceduralists have to learn new procedures while patients undergo the challenges such as slower pace of operative procedures, since the learning curves of the learner is slow and possibly unsafe ways to teach the learners. Larger health systems face the challenges of standardizing techniques and maintaining high quality and safety across the system. Having access to experts enhances the access to these procedures in many areas of the globe in emergency situations as well as elective procedures. Today’s learners are technologically savvy but the traditional method of learning does not allow them to innovate their learning process.
A paper published in Journal of Neurosurgery (JNS) titled “Virtual interactive presence for real time, long-distance surgical collaboration during complex microsurgical procedure” on August 2014 highlights the development of novel technologies that geographically extend the capabilities of individual surgeons and enhance surgical skills. The authors have developed “Virtual Interactive Presence” (VIP), a platform that allows remote participants to simultaneously view each other's visual field, creating a shared field of view for real-time surgical telecollaboration and concludes that participants were able to visually and verbally interact while identifying anatomical structures, guiding surgical maneuvers, and discussing overall surgical strategy. The paper recites the importance of telecollaboration while performing an operative surgery in the situations when there
is shortage of surgeons performing the actual surgery and finds its application in surgical training programs, remote proctoring for proficiency and expert support for rural settings.
“5G-assisted telementored surgery” is review literature published on 4 September 2019 in Wiley Online Library recites both the safety and effectiveness of this form of surgical training and supervision, as well as the technical aspects, applicability and cost/benefit ratio of this technological solution.
The same concepts of telementored surgery may be applied to all types of procedures be it operative or diagnostic in nature.
Different stakeholders have been trying to find out a cost-effective solution to the existing problem of imparting the knowledge by proceduralists as well as incorporate the relevant experience in the operative procedures, new as well as prevailing, while the patient is being operated remotely. However, the drawbacks in these solutions are that the accurately pin pointing the area in a given field of view with the help of digital markers that could be actually added while the real time streaming of the operative surgery is happening such that the learners receive the real-time audio visual feedback complemented with digital markers which can be added as a layer over the real time streaming of operative procedures. The digital markers can be selected from text markers, shape markers, color markers and other critical situation markers.
Hence there is an unmet need for a platform to make these learning curves shorter, faster and safer by bringing the experts and the learners together on a virtual platform to provide real time, precise and focused audiovisual feedback complemented with digital markers which can be added as a layer over the real time streaming of operative procedures and also create a community of experts and learners to make the procedures safer, quicker and accessible.
The present invention overcomes the drawbacks of the existing practices and allows seamless standardization to maintain high standards of safety and quality by providing instant access to experts and providing key performance data points to improve the deficiencies.

Another object of the present invention is to provide a faster and efficient system and method for bringing experts and the learners together on a virtual platform to provide real time, precise and focused audio-visual feedback on operative procedures.
Yet another object of the present invention is to provide a system and method for real-time two- way communication on the virtual platform with the help of audio-visual feedback, digital markers and critical situation markers.
Still another object of the present invention is to provide a system and method for real-time streaming of the operative procedures for learning purposes.
