State recognition of decompressive laminectomy with multiple information in robot-assisted surgery
Publication date: Available online 16 November 2019Source: Artificial Intelligence in MedicineAuthor(s): Yu Sun, Li Wang, Zhongliang Jiang, Bing Li, Ying Hu, Wei TianAbstractThe decompressive laminectomy is a common operation for treatment of lumbar spinal stenosis. The tools for grinding and drilling are used for fenestration and internal fixation, respectively. The state recognition is one of the main technologies in robot-assisted surgery, especially in tele-surgery, because surgeons have limited perception during remote-controlled robot-assisted surgery. The novelty of this paper is that a state recognition system is proposed for the robot-assisted tele-surgery. By combining the learning methods and traditional methods, the robot from the slave-end can think about the current operation state like a surgeon, and provide more information and decision suggestions to the master-end surgeon, which aids surgeons work safer in tele-surgery. For the fenestration, we propose an image-based state recognition method that consists a U-Net derived network, grayscale redistribution and dynamic receptive field assisting in controlling the grinding process to prevent the grinding-bit from crossing the inner edge of the lamina to damage the spinal nerves. For the internal fixation, we propose an audio and force-based state recognition method that consists signal features extraction methods, LSTM-based prediction and information fusion assisting in monitoring the drilling process to preven...
CONCLUSION: Using an example of GART for HIV, this study demonstrates comparative analysis of previously published cost effectiveness models yields critical information which can be used to inform the structure and specifications of new models. PMID: 31835974 [PubMed - as supplied by publisher]

Lumbar spinal stenosis is a common condition in the elderly for which costs vary substantially by region. Comparing differences between surgeons from a single institution, thereby omitting regional variation, could aid in identifying factors associated with higher costs and individual drivers of costs. The use of decision aids (DAs) has been suggested as one of the possible tools for diminishing costs and cost variation.
CONCLUSION: We have obtained important findings about older people's experiences of living with NC and preferences for physiotherapy treatment and outcomes. These will be incorporated into an evidence-based intervention and evaluated in a randomized controlled trial. Implications for rehabilitation Older people living with NC want to get back to meaningful activities and learn how to live with the threat of pain. Allied health professionals (AHPs) should be sensitive to the complex and ambiguous ways in which older people live with ageing and age-related decline. AHPs are in a position to support patients' successful trans...
