Background
Currently, haptic systems ignore the varying impedance of the human hand with its countless configurations and thus cannot recreate the complex haptic interactions. The literature does not reveal a comprehensive survey on the methods proposed and this study is an attempt to bridge this gap.
Methods
The paper includes an extensive review of human arm impedance modeling and control deployed...
Background
In image‐guided robotic interventions, an error component is related to the positioning error of the manipulator. Therefore, measuring the kinematic error is required during robot development. However, no specialized measurement device exists for this task. This study explores the possibility of using optical tracking for robot measurement.
Methods
A CNC machine is used to position an...
Background
A Baker's cyst is a pathological structure located near a kneepit, which causes discomfort and reduces mobility of the knee. It is commonly treated with aspiration, which often requires MRI scanning and US guidance. The aim of this study was to propose a novel planning solution for semi‐autonomous aspiration of the Baker's cyst using only MRI imaging.
Methods
The proposed method requires...
Background
A surgeon's tactile sense can contribute to intraoperative tumor detection, but it is limited by laparoscopic surgery.
Methods
We have developed a simple and biocompatible tactile sensor. This study aimed to design and evaluate visual and tactile feedback from the sensor for laparoscopic tumor detection. A line graph was offered through a monitor as the visual feedback. A normal force...
Background
The success of tumour neurosurgery is highly dependent on the ability to accurately localize the operative target, which may shift during the operation. Performing intraoperative brain imaging is crucial in minimally invasive neurosurgery to detect the effect of brain shift on the tumour's location, and to maximize the efficiency of tumour resection.
Method
The major objective of this...
Background
The implantation of the acetabular cup essentially determines the clinical outcome of total hip arthroplasty. To address this issue, the aim of this study was to build patient‐specific instruments (PSIs) with various reference surfaces, followed by in vitro investigations to examine the inter‐ and intra‐operator reliability as well as the overall precision of these patient‐specific templates...
Background
While endoscopic skull base surgery (ESBS) has emerged as an alternative surgical option, the limited field of view of the endoscope may lead to the surgeon's fatigue and discomfort.
Methods
The developed navigation system includes extended augmented reality (AR), which can provide an extended viewport to a conventional endoscopic view by overlaying 3D anatomical models generated from...
Background: Common surgical procedures on the mitral valve of the heart include modifications to the chordae tendineae. Such interventions are used when there is extensive leaflet prolapse caused by chordae rupture or elongation. Understanding the role of individual chordae tendineae before operating could be helpful to predict whether the mitral valve will be competent at peak systole. Biomechanical...
Objective
Recent studies with robot‐guided stereotaxy use computed tomography (CT) scans for referencing. We will provide evidence that using preoperative MRI datasets referenced with a laser scan of the patient's face is sufficient for sEEG implantation.
Methods
In total, 40 sEEG electrodes were implanted in five patients by the robotic surgical assistant (ROSA). The postoperative CT scan for...
Background
Reconstruction of the mandible with autologous transplants is a challenging task and current computer‐aided surgical planning remains cumbersome. Thus, the aim of the present study was to create an automated computational approach for this procedure.
Methods
The developed algorithm is based on curves following characteristic anatomical features. Geometrical data from a physiological...
Background
In orthopaedic trauma surgery, image‐guided procedures are mostly based on fluoroscopy. The reduction of radiation exposure is an important goal. The purpose of this work was to investigate the impact of a camera‐augmented mobile C‐arm (CamC) on radiation exposure and the surgical workflow during a first clinical trial.
Methods
Applying a workflow‐oriented approach, 10 general workflow...
