Background
The implementation of lateral ventricle puncture (LVP) operation is challenging due to the complex anatomy structure of human brains. Surgical simulator has been proved to be effective in surgical training. However, few works consider the integration of visual and haptic feedback.
Methods
Aim at achieving a realistic haptic interaction, this paper proposes a haptic‐based virtual reality...
Objective
To summarize our initial experience with robot‐assisted complete mesocolic excision (R‐CME) using a domestically produced Chinese surgical robot by a short‐term evaluation.
Methods
From March 2018 to December 2018, 25 patients with colon cancer underwent Micro Hand S R‐CME. The operative findings, morbidities and oncological findings were analysed.
Result
The median operative duration...
Background
A magnetic resonance imaging (MRI) compatible robotic system for focused ultrasound was developed for small animal like mice or rats that fits into a 9.4 T MRI scanner (Bruker Biospec 9420, Bruker Biospin, Ettlingen, Germany). The robotic system includes two computer‐controlled linear stages.
Materials and Methods
The robotic system was evaluated in a mouse‐shaped, real‐size agar‐based...
Background
Robot‐assisted pedicle screw insertion has gained popularity in the spinal surgery field. Due to high cost, these spinal robots are not extensively applied in clinical surgeries. Developing an effective robot system with low cost and high clinical acceptability is one of the future trends.
Methods
We developed a novel fluoroscopy‐based robot system for pedicle screw insertion. Four live...
Background
During minimally invasive surgery (either robotic or traditional laparoscopic), vascular injuries may occur because of inadvertent surgical tool movements or actions. These vascular injuries can lead to arterial or venous bleeding with varying degrees of severity that may be life‐threatening.
Materials and Methods
Given that a bloody spot is characterized by homogenous and uniform texture,...
Objectives
To report the 5‐year survival rates of patients undergone surgery for endometrial cancer, within a 10‐year study.
Methods
Single institution series with a minimum 2‐year follow‐up. The 5‐year survival outcomes of patients managed by robotics, laparoscopy and open surgery during the same period were compared. Multivariable analyses were performed to identify prognostic factors.
Results...
Background
Minimally invasive hepatectomy has well‐known advantages over the traditional open approach. Inherent limitations of laparoscopy make major hepatectomies and the resection of upper and posterior segments a great technical challenge. The robotic approach overcomes most of these limitations, and this technology is most useful in the resection of the deeply located caudate lobe.
Methods...
Background
Tubal anastomosis has similar pregnancy rates regardless of approach. Historically, robotic anastomosis has been associated with increased cost and operative time. We sought to perform a contemporary study of these metrics.
Methods
One hundred and nine patients were identified who underwent robotic‐assisted laparoscopic tubal anastomosis. Retrospective analysis of medical records was...
Background
We hypothesized that the total operative time of robot myomectomy (RM) is shorter than that of laparoscopic myomectomy (LM) in cases where numerous myomas are removed, due to the faster suturing time of the robotic system. To verify this, we compared the surgical outcomes of RM vs LM for the number of myomas removed.
Methods
The medical records of 144 women underwent LM and 121 women...
Background
Distal nasolacrimal duct stenosis is usually treated by head and neck surgeons with transnasal endoscopic dacryocystorhinostomy (DCR). The presented clinical study discusses advantages and drawbacks of a robot‐assisted endoscope positioning system, which allows for hands‐free visualization of the surgical field.
Material and Methods
Two patients were treated by surgical DCR. The endoscopic...
Purpose
Novel thyroidectomy techniques have been described to minimize the visible scar. Hereby, we aim to present our experience with transoral robotic thyroidectomy (TORT) without axillary access.
Material and Methods
Between August 2018 and March 2019, six eligible patients were enrolled to undergo TORT. Procedures were performed by using the Da Vinci Xi platform under intermittent intraoperative...
Background
Current laparoscopic surgical robots are teleoperated, which requires high fidelity differential motions but does not require absolute accuracy. Emerging applications, including image guidance and automation, require absolute accuracy. The absolute accuracy of the da Vinci Xi robot has not yet been characterized or compared to the Si system, which is now being phased out. This study compares...
Background
Data regarding the outcomes of pure minimally invasive techniques of radical gastrectomy are scarce. We aimed to compare short‐term post‐operative outcomes in patients undergoing totally minimally invasive radical gastrectomy with the da Vinci Xi® robotic system versus straight laparoscopy for gastric adenocarcinoma.
Methods
Between December 2013 and March 2018, robotic and laparoscopic...
Background
Fine needle insertion in the lower abdomen is difficult because of complex deflections and few image feedbacks. We aim to develop an approach for generating a straight insertion path by minimizing the needle deflection robustly based on a preoperative computer tomography (CT) image.
Method
This study presents two approaches: an insertion control strategy that performs both vibration...
Background
Training surgeons to use surgical robots are becoming part of surgical training curricula. We propose a novel method of training fine‐motor skills such as Microscopic Selection Task (MST) for robot‐assisted surgery using virtual reality (VR) with objective quantification of performance. We also introduce vibrotactile feedback (VTFB) to study its impact on training performance.
Methods...
Background
This study aimed to compare short‐ and long‐term outcomes after robotic versus laparoscopic approach in patients undergoing curative surgery for rectal cancer.
Methods
Patients undergoing elective robotic and laparoscopic resection for rectal cancer were included. Perioperative clinical characteristics, postoperative short‐ and long‐term outcomes were compared between groups.
Results...
Background
Patient‐specific instrumentation (PSI) improves accuracy of surgical operations. PSI needs software for preoperative planning and instrument design. In this study, we explain the methodology of developing a software tool for PSI guide design and preoperative planning in reverse shoulder arthroplasty (RSA).
Methods
Approaches used to prepare input data, transform them into meaningful...
Background
The improvement of the steerability and controllability of catheters is highly required because catheter‐based interventional diagnosis and therapy have become increasingly popular. However, active catheters are often complex and expensive.
Methods
This study attempts to control catheter tip by a twisted string actuator. Experiments are carried out to analyze the full actuation and bending...
Background
This study aimed to evaluate rectal pain and bowel function of the patients following robot‐assisted radical prostatectomy (RARP).
Methods
We divided 296 patients who underwent RARP into two groups depending on the intervention: NS (nerve‐sparing) group (bilateral NS, unilateral NS and bilateral partial NS) and non‐NS group (unilateral partial NS, bilateral non‐NS). Bowel function was...
In this paper, a new matrix‐based method is proposed to real‐time determine, the guidewire position inside an arterial system. The guidewire path is obtained by the optimal path method, particularly, the fusiform ternary tree method according to the principle of minimum output value of root node. An adaptive sampling strategy, and an optimization strategy based on the proximal end and distal end of...
