A Generalized Approach to Impedance Control Design for Robotic Minimally Invasive Surgery [PDF]
arXiv, 2022 Energy based control methods are at the core of modern robotic control algorithms. In this paper we present a general approach to virtual model/mechanism control, which is a powerful design tool to create energy based controllers. We present two novel virtual-mechanisms designed for robotic minimally invasive surgery, which control the position of a ...

Systolic blood pressure estimation using ECG and PPG in patients undergoing surgery [PDF]
arXiv, 2021 Background and Objectives: In a significant portion of surgeries, blood pressure (BP) is often measured non-invasively in an intermittent manner. This practice has a risk of missing clinically relevant BP changes between two adjacent intermittent BP measurements. This study proposes a method to non-invasively estimate systolic blood pressure (SBP) with

Incidence of postoperative acute kidney injury in patients with chronic kidney disease undergoing minimally invasive valve surgery [PDF]
, 2013 BackgroundWe hypothesize that minimally invasive valve surgery in patients with chronic kidney disease (CKD) is superior to a conventional median sternotomy.MethodsWe retrospectively analyzed 1945 consecutive patients who underwent isolated valve surgery.

Segmenting Medical Instruments in Minimally Invasive Surgeries using AttentionMask [PDF]
arXiv, 2022 Precisely locating and segmenting medical instruments in images of minimally invasive surgeries, medical instrument segmentation, is an essential first step for several tasks in medical image processing. However, image degradations, small instruments, and the generalization between different surgery types make medical instrument segmentation ...

Quantification of Robotic Surgeries with Vision-Based Deep Learning [PDF]
arXiv, 2022 Surgery is a high-stakes domain where surgeons must navigate critical anatomical structures and actively avoid potential complications while achieving the main task at hand. Such surgical activity has been shown to affect long-term patient outcomes.

Left atrial anomalous muscular band as incidental finding during video-assisted mitral surgery [PDF]
, 2018 Congenital fibromuscular bands have been described inleft ventricle or right atrium and have been diagnosed by echocardiography and CT scan. The first report of anomalous band in the left atrium was described in 1897 by Rollestone (1).
