A Surgeon Preference-Guided Autonomous Instrument Tracking Method With a Robotic Flexible Endoscope Based on dVRK Platform

RA-L 2022

In minimally invasive surgery, endoscopes serve as the eyes of surgeon. To avoid fatigue in manual endoscope steering, robotic endoscope holders have been developed. Unfortunately, existing robotic endoscope holders are not widely adopted due to the poor surgeon-robot cooperation. In this work, we d

Design and Analysis of a Long-range Magnetic Actuated and Guided Endoscope for Uniport VATS

ICRA 2022poster

This paper presents a long-range magnetic actuated and guided endoscope for uniport video-assisted thoracic surgery (VATS). In VATS, the incision is quite narrow and part of the chest wall may be very thick. So, the magnetic endoscope system is required to produce sufficient attractive force at a co…

Deep Learning Assisted Robotic Magnetic Anchored and Guided Endoscope for Real-Time Instrument Tracking

RA-L 2021

This letter presents the first case of implementing deep-learning based instrument tracking on a magnetic anchored surgical endoscope. The compact magnetic actuated endoscope has a unique structure that allows operations near the anchor surface, ideal for video assisted thoracoscopic surgery (VATS).

Visual Servo Control of a Novel Magnetic Actuated Endoscope for Uniportal Video-Assisted Thoracic Surgery

RA-L 2019

This letter presents the first case of implementing visual servo control on a magnetic anchored endoscope. The novel magnetic actuated endoscope is designed for uniportal video-assisted thoracic surgery (VATS).Itis compact and has a workspace close to the chest wall, which is suitable for operation

A Novel Magnetic Anchored and Steered Camera Robot for Single Port Access Surgery

ICRA 2018poster

This paper presents a novel magnetic anchored and steered camera robot intended for minimally invasive surgery (MIS), particularly for single port access (SPA) surgery. The design aims to achieve both compactness and a planar pan/tilt workspace (instead of hemispheric) to lower robot footprint in ve…

Design and prototyping of a soft magnetic anchored and guidance endoscope system

IROS 2017poster

Minimally invasive surgery (MIS) has seen substantial development in recent decades. In MIS, particularly in laparoendoscopic single site (LESS) surgery, the surgical site is always crowded. One potential solution is the magnetic anchored and guidance system (MAGS), which liberates instruments from…
