Introduction
To date, no anti‐reflux operations have been reported with the new da Vinci Single‐Port (single port (SP)) robotic platform. We aimed to describe this novel surgical approach and evaluate its safety and feasibility.
Methods
All robotic SP operations were performed under an Institutional Review Board approved protocol.
Results
Two patients underwent robotic SP anti‐reflux surgery...
Background
We present an artificial intelligence framework for vascularity classification of the gallbladder (GB) wall from intraoperative images of laparoscopic cholecystectomy (LC).
Methods
A two‐stage Multiple Instance Convolutional Neural Network is proposed. First, a convolutional autoencoder is trained to extract feature representations from 4585 patches of GB images. The second model includes...
Background
This preclinical study emulating the clinical environment quantitatively analysed the accuracy of pedicle screw insertion using a navigated robotic system.
Methods
Pedicle screws were placed from T7 to L5 in the whole‐body form of a cadaver. After the insertion of multiple artificial markers into each vertebra, errors between the planned insertion path and the inserted screw were quantified...
Purpose
Vision‐based tissue tracking is a significant component for building efficient autonomous surgical robot system. While the methodology involves various challenges caused by occlusion, deformation and appearance changes.
Methods
We propose a novel correlation filter tissue tracking framework for minimally invasive surgery. Our model contains the innovative design of synthetic features, a...
Background
The purpose of this study was to compare component alignment using two‐dimensional (2D) and three‐dimensional (3D) measurements following total knee arthroplasty (TKA) with a new robotic system.
Methods
A total of 38 patients underwent TKA with the robotic system. Cutting errors were measured. Errors in 2D and 3D component alignments from the planned angle, validated cutting angle, and...
Background
The sentinel lymph node (SLN) procedures using indocyanine green (ICG) have recently been performed worldwide. The aim of this study was to emphasise the safety of robot‐assisted modified radical hysterectomy (RAMRH) with removal of the lymphatic vessels (RLV) using ICG in endometrial cancer according to a single surgeon's experience.
Methods
Robot‐assisted modified radical hysterectomy...
Background
This systematic review aims to critically appraise the intraoperative use of augmented and mixed reality technology to improve surgical outcomes.
Method
A literature search of PubMed, Scopus, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and WHO ICTRP was performed in accordance with Cochrane Handbook for Systematic Reviews of Interventions.
Results
This review...
Background
To provide appropriate surgical training guidance, some skill evaluation and safety detection methods have been developed. However, these methods are difficult to provide predictive information for trainees. This paper proposes a new approach for real‐time trajectory prediction of the laparoscopic instrument tip to improve surgical training and the patient safety.
Methods
This paper...
Background
Continuous curvilinear capsulorhexis (CCC) requires surgeons to manipulate fragile eye tissue at the microscale. The limited perceptual accuracy of surgeons makes it difficult to precisely position the forceps. Robot technology provides a feasible way to improve the performance of CCC.
Methods
To provide real‐time and high‐precision forceps position feedback to the robot, and extract...
Background
Accurate and real‐time biomechanical modelling of the liver is a major challenge in computer‐assisted surgery. Finite element method is often used to predict the deformation of organs for its high modelling accuracy. However, its high computation cost hinders its application in real time, such as virtual surgery simulations.
Method
A liver model with biomechanical properties similar...
Background
Prostate Cancer screening based on manual palpation is subjective. Robotic palpation systems can objectively acquire stiffness conditions of the prostate.
Methods
A 2DoF cable driven robotic system for prostate palpation is proposed. An indirect method to estimate the contact force based on cable tension observation is presented. Kinematic models and a joint angle estimation method to...
Background
Percutaneous vertebroplasty (PVP) is one of the most effective treatments for patients with vertebral fracture that need surgical treatment, and surgical robotics are promising tools to provide surgeons with improved precision, surgical efficiency and reduce radiation exposure. However, there are currently few robotics that are developed to help assist with PVP.
Methods
A new spinal...
Background
The method of MRI (Magnetic Resonance Imaging) image‐guided robot for prostate seed implantation has developed rapidly in recent years. During the operation, although the puncture effect guided by MRI is very good, it is difficult for conventional robots driven by motors to work normally in this environment, which reduces the accuracy of seed implantation and affects the treatment effect...
Introduction
Robotic surgery has expanded on it's surgical application and it is also noted an increase in surgical procedures complexity. Occurrence of emergency situations that require conversion of the minimally invasive access route to open access routes is uncommon. The urgent undocking of the robotic platform is a complex and neglected process in robotic surgery training.
Objective
To establish...
Background
In robotic surgery, a surgeon controls a surgical robot through a master manipulator in motion scaled teleoperation environment. However, there are no clear criteria for the master's workspace.
Methods
From the user experiment, we proposed an Ergonomic Comfort Workspace considering ergonomics and performed a verification experiment using the actual surgeons' dataset.
Results
From the...
Background
We lack data regarding the economic cost of robot‐assisted surgical procedures in urology. We aimed to assess the medico‐economic impact of onco‐urological robot‐assisted surgery.
Methods
All patients who underwent robot‐assisted radical prostatectomy (RARP) or robot‐assisted partial nephrectomy (RAPN) in 2019 were included. Cost assessment included the costs of surgery, hospital stay,...
Background
The gold standard workflow for targeting structures in the brain involves manual path planning. This preoperative manual path planning is very time‐intensive and laborious, especially when some outcome measures such as maximum ablation and penetration depth has to be optimised.
Methods
Our novel path planner generates an optimal path which maximises the hippocampus penetration and distance...
Background
We aim to analyse the safety and feasibility of the DaVinci Single Port (SP) platform in general surgery.
Methods
A prospective series of robotic SP transabdominal pre‐peritoneal inguinal hernia repairs (SP‐TAPP) and cholecystectomies (SP‐C) (off‐label) were analysed. Primary endpoints were safety and feasibility defined by the need for conversion and incidence of perioperative complications...
Background
Epidural anaesthesia is a Percutaneous Procedure (PP) which plays a crucial role in surgical procedures, where accurate needle insertion is still challenging. The objective of this work is to present a Tuohy needle path planning, which allows an anaesthesiologist to drive semiautonomously, with the assistance of a teleoperated robot, the tip of the needle during this PP.
Methods
We capture,...
