Validation of Machine Learning-Based Automated Surgical Instrument Annotation Using Publicly Available Intraoperative Video.
Operative neurosurgery (Hagerstown, Md.)
May 26, 2022
BACKGROUND: Intraoperative tool movement data have been demonstrated to be clinically useful in quantifying surgical performance. However, collecting this information from intraoperative video requires laborious hand annotation. The ability to automa...
Evaluation of user-interfaces for controlling movements of virtual minimally invasive surgical instruments.
The international journal of medical robotics + computer assisted surgery : MRCAS
May 5, 2022
BACKGROUND: Recent tele-mentoring technologies for minimally invasive surgery (MIS) augments the operative field with movements of virtual surgical instruments as visual cues. The objective of this work is to assess different user-interfaces that eff...
Click-on fluorescence detectors: using robotic surgical instruments to characterize molecular tissue aspects.
Journal of robotic surgery
Apr 9, 2022
Fluorescence imaging is increasingly being implemented in surgery. One of the drawbacks of its application is the need to switch back-and-forth between fluorescence- and white-light-imaging settings and not being able to dissect safely under fluoresc...
Transfer of learned dynamics between different surgical robots and operative configurations.
International journal of computer assisted radiology and surgery
Apr 6, 2022
PURPOSE: Using the da Vinci Research Kit (dVRK), we propose and experimentally demonstrate transfer learning (Xfer) of dynamics between different configurations and robots distributed around the world. This can extend recent research using neural net...
Lightweight Deep Neural Network for Articulated Joint Detection of Surgical Instrument in Minimally Invasive Surgical Robot.
Journal of digital imaging
Mar 9, 2022
Vision-based detection and tracking of surgical instrument are attractive because it relies purely on surgical instrument already in the operating scenario. The vision knowledge of the surgical instruments is a crucial piece of topic for surgical tas...
Surgical assistant manipulator with diagonal joints and multi-stage telescopic screws for laparoscopic solo surgery.
International journal of computer assisted radiology and surgery
Jan 6, 2022
PURPOSE: A surgeon in a sterilized area can perform robotically assisted laparoscopic solo surgery while controlling a laparoscope-holding robot for view stabilization and a forceps robot for pulling organs. At present, no locally operated surgical a...
Analysis of tendon tension and hysteresis by tendon twisting and development of anti-twist tendon mechanism of robotic surgical instruments.
The international journal of medical robotics + computer assisted surgery : MRCAS
Jan 5, 2022
BACKGROUND: Control of the joints of robotic surgical instruments is difficult owing to hysteresis, and tendon twisting due to axial rotation of surgical tools also causes hysteresis. Therefore, a new mechanism is needed to prevent tendon twisting.
Initial Experience of Robot-Assisted Laparoscopic Nephroureterectomy in Japan: A Useful Technique Using a Vessel Sealing Device for Securing a Good Surgical Field and Efficient Sealing.
Asian journal of endoscopic surgery
Dec 7, 2021
INTRODUCTION: Although robot-assisted nephroureterectomy (RANU) has been increasingly used worldwide, the history of RANU remains short, and the optimal surgical method for performing RANU has yet to be established. Here we introduce the ideal approa...
Automated recognition of objects and types of forceps in surgical images using deep learning.
Scientific reports
Nov 19, 2021
Analysis of operative data with convolutional neural networks (CNNs) is expected to improve the knowledge and professional skills of surgeons. Identification of objects in videos recorded during surgery can be used for surgical skill assessment and s...
Design of a dexterous robotic surgical instrument with a novel bending mechanism.
The international journal of medical robotics + computer assisted surgery : MRCAS
Sep 28, 2021
BACKGROUND: The robot-assisted minimally invasive surgery (RMIS) has developed rapidly in recent years, requiring highly articulated instruments to enable surgeons to perform complicated and precise procedures.
