Background
The operation object of robot‐assisted fracture reduction surgery is the musculoskeletal tissue with rigid‐compliance coupling characteristics. It is necessary to improve the interactive compliance and safety between the reduction robot and the musculoskeletal tissue.
Method
An adaptive variable impedance position/force tracking control strategy based on friction compensation is proposed...
Background
During the robot‐assisted pelvic fracture reduction process, the clamping instrument are subjected to the large reduction force from the robot, resulting in inevitable great stress concentration and deformation of the bone pins, affecting the fracture reduction accuracy.
Method
A compact and easily‐to‐adjust clamping instrument with active variable stiffness is designed. The relationship...
Background
Magnetic resonance imaging (MRI)‐guided biopsies are an accurate, but technically challenging, method for screening and diagnosis of breast lesions. This study assesses the safety and efficacy of an Image Guided Automated Robot (IGAR) in performing breast biopsies compared to manual procedures.
Methods
Safety was determined from adverse events (AEs) and device deficiencies. Efficacy...
Background
Ultrasound (US) imaging for scoliosis assessment is challenging for a non‐experienced operator. The robotic scanning was developed to follow a spinal curvature with deep learning and apply consistent forces to the patient's back.
Methods
Twenty three scoliosis patients were scanned with US device both, robotically and manually. Two human raters measured each subject's spinous process...
Purpose
Endoscopic sinus surgery (ESS) has been recognized as an effective treatment modality for paranasal sinus diseases. Over the past decade, continuum robots (CRs) for ESS have been studied, but there are still some challenges. This paper presents a review on the scientific studies of CRs for ESS.
Methods
Based on the analysis of the anatomical structure of the paranasal sinus, the requirements...
Background
We aimed to evaluate the accuracy and safety of a novel self‐tapping bone fiducial as a registration technique for stereoelectroencephalography (SEEG) implantation.
Methods
Each patient was installed with five bone fiducial markers. All procedures were performed using the same Sinovation robot system. The accuracy was determined by calculating the target point error (TPE) and the entry...
Background
How to precisely protect and preserve anterior and posterior vagal trunks and all their branches during the procedure of splenectomy and azygoportal disconnection is studied rarely. We firstly developed a vagus nerve‐guided robotic‐assisted laparoscopic splenectomy and azygoportal disconnection (VGRSD). The aim of this study was to evaluate whether VGRSD is feasible and safe and to determine...
The usual Lewinnek orientation for cup positioning in total hip arthroplasty is not suitable for all patients as it does not consider the patient mobility. We propose an ultrasound‐based approach to compute a Functional Safe Zone (FSZ) considering daily positions. Our goal was to validate it, and to evaluate how the input parameters impact the FSZ size and barycentre. The accuracy of the FSZ was first...
Background
The single port surgical robot causes only one incision and brings many benefits to patients. It is very challenging to design a single port surgical robot that causes a smaller incision than current products.
Methods
This paper presents a highly compact single port laparoscopy surgical robot, which makes full use of the space of the port and only needs a 15 mm‐diameter port. The robot...
Background
Neonate patients have a reduced thoracic cavity, making thoracoscopic procedures even more challenging than their adult counterparts.
Methods
We evaluated five control strategies for robot‐assisted thoracoscopic surgical looping in simulations and experiments with a physical robotic system in a neonate surgical phantom. The strategies are composed of state‐of‐the‐art constrained optimization...
Background
The purpose of this study was to access the accuracy of cortical bone trajectory screw placement guided by spinous process clamp (SPC).
Methods
Eight formalin‐treated cadaveric lumbar specimens with T12‐S1 were used. A total of 96 screws were implanted in eight lumbar specimens.
Results
In the freehand (FH) group, clinically acceptable placement (grade A and B) was 40 screws (83.3%),...
Duplex kidney and ureter is a congenital malformation. Few patients present with hydronephrosis caused by obstruction of the ureteropelvic junction of the duplex kidney, but lower kidney calculi caused by a duplex kidney abnormality is rare. This study reports a case of a duplex kidney and ureter complicated by multiple calculi in the duplex lower kidney. Percutaneous nephrolithotomy combined with...
Background
Robotic scope assistant systems are used to visualise and navigate the operative field during a laparoscopic surgery. The objective of this work is to design a surgical scope adapter that enables control of different scope types (zero‐degree, angulated, and articulated), and can be connected to any six degree‐of‐freedom robotic manipulator for usage as a robotic scope assistant system...
Background
Robot‐assisted pelvic fracture closed reduction (RPFCR) positively contributes to patient treatment. However, the current path planning suffers from incomplete obstacle avoidance and long paths.
Method
A collision detection method is proposed for applications in the pelvic environment to improve the safety of RPFCR surgery. Meanwhile, a defined orientation planning strategy (OPS) and...
Background
Computer‐assisted Surgery system (CAS) is an effective medical imaging simulation tool, which is widely used in preoperative planning of surgery. The objective of this study is to investigate the clinical application of CAS in pediatric mediastinal tumor resection.
Methods
This retrospective study investigated 74 children who underwent mediastinal tumor resection between June 2008 and...
Background
The aim of this study was to compare the intraoperative and postoperative outcomes between a robot‐assisted versus a navigated transpedicular fusion technique.
Methods
This retrospective analysis included patients who underwent transpedicular posterior fusion of the spine due to trauma, pyogenic spondylodiscitis and osteoporosis. Surgery was done either with a robot‐assisted or a percutaneous...
Background
The operative microscope (OM) represents, to date, the standard for neurosurgical procedures. However, new technologies have been proposed during the latest years to overcome its limitations, from high‐quality exoscopes to complex robotised visualisation systems. We report our preliminary experience with a novel digital robotised microscope, the BHS RoboticScope (RS), for minimally invasive...
Background
Several automated skill‐assessment approaches have been proposed for robotic surgery, but their utility is not well understood. This article investigates the effects of one machine‐learning‐based skill‐assessment approach on psychomotor skill development in robotic surgery training.
Methods
N = 29 trainees (medical students and residents) with no robotic surgery experience performed...
Background
To explore the clinical application of robotic‐assisted surgery in paediatric solid tumours and to explore its feasibility.
Methods
From 2015 to 2022, 53 children with solid tumours underwent robotic‐assisted surgery in our centre were retrospectively analysed.
