Objectives
To investigate the safety of robotic surgery during COVID‐19 pandemic concerning new‐acquired COVID‐19 infections for patients and healthcare workers.
Patients
We performed a retrospective single‐centre cohort study of patients undergoing robotic surgery in initial period of COVID‐19 pandemic. Patients and healthcare workers COVID‐19 infection status was assessed by structured telephone...
Background
In the transrectal ultrasound (TRUS)‐guided transperineal prostate biopsy, doctors determine the biopsy target by observing the prostate region in TRUS images. However, ultrasound images with low imaging quality make doctors easy to be interfered when determining the biopsy route, which reduces the biopsy success rate.
Methods
This paper introduces the guidance method of magnetic resonance...
Background
Intraocular surgery is one of the most challenging microsurgeries. Unintended movements of human hand and lack of force feedback can seriously affect surgical safety.
Methods
We developed a novel master–slave robotic system with force feedback to assist intraocular surgeries. Isomorphism design was adopted to achieve intuitive control of the system. Contact force between instrument tip...
Objective
This study aimed to evaluate the difference of two various robotic technology applied in R‐ Total mesorectal excision (TME).
Methods
From May 2017 to December 2018, consecutive patients with rectal cancer who underwent da Vinci R‐TME or Micro Hand S R‐TME were enrolled. The comparative study was conducted on Short‐term Operative, Oncological, and Functional Outcomes between two type of...
Background
In this study, we aimed to compare the stability of traditional tension band wiring (TBW) and screw combined TBW (SC‐TBW) fixation methods performed for a transverse olecranon osteotomy‐fracture during different degrees of elbow movement by using finite element analysis.
Methods
Three‐dimensional solid modeling of the olecranon was obtained by computed tomography images. Transverse olecranon...
Background
Optical tracking systems (OTSs) are essential components of many modern computer assisted orthopaedic surgery (CAOS) systems but patient movement is often neglected in the evaluation of the accuracy. The aim of this study was to develop a representative test to assess the accuracy of OTSs including patient movement and demonstrate the effect of pointer design and OTS choice.
Method
A...
Background
Robotic‐assisted techniques in colorectal surgery have dramatically increased. Comparative data on the management of uncomplicated and complicated diverticulitis using robotics is lacking. The purpose of this study is to examine outcomes of patients who underwent robotic‐assisted resection in diverticulitis.
Methods
A prospectively maintained database performed by a single surgeon was...
Background
The hysteretic forces arising from the electric cables that externally run along the robotic joints are the main disturbance to the precise parameter estimation of gravity compensation model, for the Master Tool Manipulator (MTM) of the da Vinci Research Kit (dVRK). Because such nonlinear disturbance forces and the gravitational forces are often hybrid and in the same magnitude.
Methods...
Background
Pancreaticoduodenectomy (PD) is one of the most demanding interventions for digestive surgeons. R0 resection is a key point for the overall survival and disease‐free survival. Total mesopancreas excision (TMpE) has been described by laparotomy but laparoscopy did not provide good results probably because of the technical difficulties of the approach. We propose a standardised total robotic...
Background
The Senhance® robotic surgery system is a novel robotic platform used in several European and World centres. We present our experience in urologic surgery using this platform.
Patients and Methods
From May 2019 to December 2020, we performed 30 operations of upper urinary tract (UUT) and 70 extraperitoneal radical robotic prostatectomies (RRP). Relevant data were prospectively collected...
Background
Needle insertions have been used in several minimally invasive procedures for diagnostic and therapeutic purposes. Real‐time position of the needle tip is an important information in needle steering systems.
Methods
This work introduces a robot‐assisted ultrasound tracking (R‐AUST) system integrated with a needle shape prediction method to provide 3D position of the needle tip. The tracking...
Background
Poor reduction can lead to complications such as deformity and delayed fracture healing. We introduce a 3D printed external fixator technology that can assist in fracture reduction and fixation.
Methods
A fractured long bone was first fixed by a temporary external fixator and then scanned with computed tomography. Three‐dimensional reconstruction of the contour and bone fragments of...
Background
The conventional hand‐held minimally invasive surgical devices commonly suffer from non‐intuitive manipulability and restricted flexibility for operation.
Methods
A hand‐held surgical device with enhanced intuitive manipulability and stable grip force was proposed for minimally invasive surgery (MIS). The dexterous instrument and isomorphic handle were designed, and the cable transmission...
Background
During flexible ureteroscopy (FURS), surgeons may lose orientation due to intrarenal structural similarities and complex shape of the pyelocaliceal cavity. Decision‐making required after initially misjudging stone size will also increase the operative time and risk of severe complications.
Methods
A intraoperative navigation system based on electromagnetic tracking (EMT) and simultaneous...
Background and Aim
Most of the mixed reality models used in the surgical telepresence are suffering from the discrepancies in the boundary area and spatial–temporal inconsistency due to the illumination variation in the video frames. The aim behind this work is to propose a new solution that helps produce the composite video by merging the augmented video of the surgery site and virtual hand of the...
Objective
An objective assessment of robotic assistance in colorectal surgery.
Background
There is a lack of objective evidence behind the claims of superior optics and improved ergonomics with robotics. This study introduces a novel method of assessing how robotics facilitates colorectal surgery.
Methods
Operative videos of laparoscopic and robotic surgeries were reviewed. Two components were...
Background
This study aimed to compare the surgical outcomes and cost of robotic single‐site radical hysterectomy (RSSRH) versus robotic multiport radical hysterectomy (RMPRH) with pelvic lymph node dissection in early stage cervical cancer.
Methods
Sixty‐two patients with early stage cervical cancer were recruited between November 2011 and July 2017 and underwent RSSRH (20 patients) and RMPRH...
Background
Robotic‐assisted laparoscopic Heller myotomy has been proposed as an alternative minimally invasive approach to traditional laparoscopy for the treatment of achalasia. This systematic review aims to compare the safety and post‐operative outcomes of the two procedures.
Methods
Systematic literature search was performed in MEDLINE through Ovid, Scopus and Cochrane to identify clinical...
Background
The purpose of this study was to compare the accuracy of this new HURWA robotic‐assisted total knee arthroplasty (TKA) technique to the accuracy of the conventional technique in a sawbone model.
Methods
The HURWA robotic‐assisted TKA system was applied in the robotic group. After bone resection, all of these sawbones were scanned by the use of a structured light scanning system. Measurements...
