Precision Improvement and Delay Reduction in Surgical Telerobotics

Abstract

The field of medicine is greatly benefited by telerobotic surgeries. It allows the surgeon to reach the patient remotely. Traditional surgical telerobotic techniques had several drawbacks mainly due to communication delay and lack of precision. Signal latency also causes significant delay in operations. This also causes the risk of increased human errors. The surgical workflow can be altered by the addition of features like self-correction and self-automation. In this paper, we reduce the delay in telerobotic surgery using supervisory control approach and apply a haptic feedback to regulate safety. Motion scaling technique is used to combat responses in delayed environment as well as to improve the accuracy of the system. Augmented reality, improved functional design, comfort and skills along with the ability to reach the patient remotely promotes the wide use of surgical telerobotics.

Current applications and future trends of artificial senses in fish freshness determination: A review

“…Computer vision is a field of artificial intelligence that electronically mimics human vision by automatically extracting useful information from the observed images by analyzing the theoretical algorithmic bases (Kulcu & Kulcu, 2018). Computer vision is a subfield of artificial intelligence, and the evolution of artificial intelligence and machine learning is causing more improvements and upgrades in computer vision technology (Manoharan & Ponraj, 2019; Wang, 2019).…”

Typing Eyes: A Human Computer Interface Technology

“…et al [14] S. Smys et al [15] provides the use of the "big data analytics for smart cloud-fog based applications." in the hospitals and the author Manoharan et al [16] address the necessity in the improving the precision and the delay reduction in the surgical robots. The above references from [10][11][12][13][14][15][16] are to be utilized in the future scope of the paper and the references [17][18][19][20][21] provides the basic steps in developing the proposed typing eyes for the dis abled and the elderly.…”
