Background
Remote‐controlled robotic vascular interventional surgery can reduce radiation exposure to interventional physicians and improve safety. However, inconvenient operation and lack of force feedback limit its application.
Materials and Methods
A new wearable robotic system for vascular interventional surgery is designed, which is more flexible in operation. It ensures the safety of surgery...
Background
This study aims to develop a new dental implant robotic system (DIRS) to relieve the burden and enhance the quality of dental implant surgery.
Methods
The implanting actuator and system controller are two parts. The implanting actuator is designed on the basis of the RCM mechanism, with its kinematics modelled. Besides, a multi‐DOF admittance control strategy and a hybrid position‐admittance...
Background
Cochlear‐implant electrode arrays (EAs) are currently inserted with limited feedback, and impedance sensing has recently shown promise for EA localisation.
Methods
We investigate the use of impedance sensing to infer the progression of an EA during insertion.
Results
We show that the access resistance component of bipolar impedance sensing can detect when a straight EA reaches key...
Background
No consensus has been reached on operative procedures since a limited case series of robot‐assisted inferior vena cava thrombectomy (RA‐IVCT) and robot‐assisted radical nephrectomy (RA‐RN) have been described.
Methods
The clinical data of 21 patients who underwent RA‐IVCT and RA‐RN were retrieved from the database. Preoperative preparation was used for assessment of the tumour. Surgical...
Background
In order to provide accurate and reliable image guidance for augmented reality (AR) spinal surgery navigation, a spatial registration method has been proposed.
Methods
In the AR spinal surgery navigation system, grayscale‐based 2D/3D registration technology has been used to register preoperative computed tomography images with intraoperative X‐ray images to complete the spatial registration,...
Background
Ureteral injury is common during gynaecological laparoscopic surgery. Real‐time auto‐segmentation can assist gynaecologists in identifying the ureter and reduce intraoperative injury risk.
Methods
A deep learning segmentation model was crafted for ureter recognition in surgical videos, utilising 3368 frames from 11 laparoscopic surgeries. Class activation maps enhanced the model's interpretability,...
Background
Robotic puncture system (RPS) consists of an optical tracking system (OTS) and a robotic arm gripping the puncture needle. Typically, the RPS requires hand‐eye calibration before the surgery in order to obtain the relative position between the OTS and the robotic arm. However, if there is any displacement or angular deviation in either the robotic arm or the OTS, the calibration results...
Background
Minimal invasive surgery in hepatobiliary and pancreatic (HBP) surgery has been accepted worldwide in recent years. However, applications of single‐site laparoscopic surgery in complex HBP surgery have been limited due to difficulty in manoeuvring instruments and the limited range of motion resulting from clashing instruments.
Methods
To overcome the limitations, we have used the Da...
Background
The main objective of this study was to investigate the impact of robot‐assisted laparoscopic resection on paravertebral tumours using the anterior peritoneal approach.
Methods
A retrospective analysis to identify patients with paravertebral tumours. A total of 21 patients, who underwent robot‐assisted laparoscopic transabdominal anterior approach surgery from March 2012 to August 2020...
Introduction
Little information is known regarding the energy expenditure of the surgeon during total hip arthroplasty (THA). We sought to compare the energy expenditure associated with femoral broaching using two techniques: manual and automated.
Methods
We recorded energy expenditure, minute ventilation, heart rate, and total broaching time of a single surgeon while broaching the femoral canal...
Background
To summarise the application of minimally invasive surgery for female primary pelvic retroperitoneal tumours (PPRTs).
Methods
The clinical data of PPRT in a hospital between January 2017 and August 2022 were retrospectively collected. Surgical outcomes for cystic and solid tumours and two minimally invasive techniques were compared.
Results
99 patients were included. Cystic tumours...
Background
This study aimed to assess clinical results in terms of intraoperative outcomes, recovery and recurrence of our robotic technique for the treatment of patients affected by simultaneous inguinal and umbilical hernia, providing technical details to facilitate multiquadrant surgery in robotic hernia repair.
Methods
Data from patients affected by simultaneous primary inguinal and umbilical...
Objective
This study evaluates the precision of a commercially available spine planning software in automatic spine labelling and screw‐trajectory proposal.
Methods
The software uses automatic segmentation and registration of the vertebra to generate screw proposals. 877 trajectories were compared. Four neurosurgeons assessed suggested trajectories, performed corrections, and manually planned pedicle...
Introduction
Understanding surgical workflow is critical for optimizing efficiencies and outcomes; however, most research evaluating workflow is impacted by observer subjectivity, limiting its reproducibility, scalability, and actionability. To address this, we developed a novel approach to quantitatively describe workflow within robotic‐assisted lobectomy (RL). We demonstrate the utility of this...
Background
Central pancreatectomy (CP) is an ideal parenchyma‐sparing procedure. The experience of r robotic central pancreatectomy (RCP) is very limited.
Materials and Methods
Patients undergoing CP were included. Comparisons were made between RCP and open central pancreatectomy (OCP) groups.
Results
The most common lesion in patients undergoing CP was serous cystadenoma (35.5%). The median...
Background
The aim of this study was to present our initial experience of gasless robotic single‐port cholecystectomy (RSPC).
Methods
We reviewed 48 patients who underwent gasless RSPC with a da Vinci SP Robotic Surgical System. Demographic data, intra‐operative results, and postoperative outcomes were evaluated.
Results
Gasless RSPC was successfully performed in 48 of 53 patients. Five patients...
Purpose
The Da Vinci SP robot system was recently introduced, but its safety and feasibility for rectal cancer compared with the currently used robot system have not been reported.
Methods
This was a single‐centre retrospective study. Data from patients who underwent abdominal total mesorectal excision (TME) from October 2015 to October 2022 were analysed. After propensity score matching, the short‐term...
Sinaflex robotic telesurgery system has been introduced recently to provide ergonomic postures for the surgeon along with dexterous workspace for robotic telesurgery. The robot is described, and the forward and inverse kinematics are derived and validated by an experiment. The robot and operational workspaces and their dexterity are investigated and compared using the data collected during a dog vasectomy...
Background
To assess the accuracy of robot‐assisted Magerl screw placement and explore the factors affecting the accuracy.
