Background
Endovascular interventional surgery (EIS) is performed under a high radiation environment at the sacrifice of surgeons' health. This paper introduces a novel endovascular interventional surgical robot that aims to reduce radiation to surgeons and physical stress imposed by lead aprons during fluoroscopic X‐ray guided catheter intervention.
Methods
The unique mechanical structure allowed...
Background
Evidence suggests that transoral robot‐assisted surgery is becoming increasingly common, yet current systems are incapable of sufficiently reaching the glottis or subglottic areas. This paper presents a teleoperated tubular continuum robot prototype for laryngeal surgery in a feasibility study.
Methods
A tubular continuum robot prototype is used to perform basic surgical examination...
Background
A virtual guidance framework is used to assist the conventional method of virtual implant planning system (VIPS). The study null hypothesis was that its screw placement accuracy is equal to that of conventional VIPS.
Methods
In 34 distal radius sawbone models, 3D implant planning was performed. A camera attached to the surgical drill was used to support screw positioning. Differences...
Background: 3D reconstruction algorithms are of fundamental importance for augmented reality applications in computer‐assisted surgery. However, few datasets of endoscopic stereo images with associated 3D surface references are currently openly available, preventing the proper validation of such algorithms. This work presents a new and rich dataset of endoscopic stereo images (EndoAbS dataset).
Methods:...
Background
Human–computer interaction (HCI) is an important feature of augmented reality (AR) technology. The naturalness is the inevitable trend of HCI. Gesture is the most natural and frequently used body auxiliary interaction mode in daily interactions except for language. However, there are often meaningless, subconscious gesture intervals between the two adjacent dynamic gestures. So, continuous...
Background
The continuum robot is widely used in minimally invasive surgery (MIS) because of its flexibility, dexterity and safety. However, because of the friction in the transmission system, backlash, and shape error from nominal kinematics, the tracking accuracy of the continuum robot is low, which may damage the tissues and organs during surgery. A novel error compensation method is presented...
Background
With the development of laser‐assisted platforms, the outcomes of cataract surgery have been improved by automating several procedures. The cataract‐extraction step continues to be manually performed, but due to deficiencies in sensing capabilities, surgical complications such as posterior capsule rupture and incomplete cataract removal remain.
Methods
An optical coherence tomography...
Background
Physics‐based vascular modelling is an essential issue to be addressed in the development of the endovascular interventional surgery training system, which helps to shorten the training period of novice surgeons to obtain dexterous skills of surgical operation.
Methods
A blood vessel model based on tensor‐mass method (TMM) is formulated and implemented in this context. A multimodel representation...
Background
In cerebrovascular intervention (CVI), the use of robots has considerable advantages over conventional surgery. This study introduces a remote‐controlled robotic system, including the first in vivo proof‐of‐concept trial.
Methods
The robotic system uses a master–slave control strategy. Omega 3 was selected as the master manipulator, and the slave side executed the procedure of inserting...
Background: Respiratory‐induced motion (RIM) causes uncertainties in localizing hepatic lesions, which could lead to inaccurate targeting during interventions. One approach to mitigate the problem is respiratory motion estimation (RME), in which the liver motion is estimated by measuring external signals called surrogates.
Methods: A learning‐based approach has been developed and validated to estimate...
Background
Unlike a manual surgical instrument, a surgical instrument used in robot‐assisted minimally invasive surgery (MIS) is configured with a wrist to improve flexibility in surgical operation. However, this configuration has a shortcoming that leads to coupled motion between the wrist and end‐effector.
Methods
Three methods are presented to eliminate the coupled motion between the wrist and...
Background
The quantitative morphological analysis of the trochlear region in the distal femur and the precise staging of the potential dysplastic condition constitute a key point for the use of personalized treatment options for the patella‐femoral joint. In this paper, we integrated statistical shape models (SSM), able to represent the individual morphology of the trochlea by means of a set of...
Purpose/Background
In 2017, an estimated 39 910 people will receive a new diagnosis of rectal cancer. Current surgical guidelines limit transanal excision of early rectal neoplasia to 8 cm from the anal verge. We report that R0 resection of higher rectal cancers is possible using transanal robotic microsurgery.
Methods/Interventions
Ten cases of robotic assisted transanal surgery for early stage...
In the last 15 years, hip arthroscopy has become increasingly popular in addressing femoroacetabular impingement (FAI) because of its minimally invasive approach. However, assessing the adequacy of bone resection when correcting FAI can be difficult because visualisation and spatial awareness of the joint are poor. Recent advances in technology in the field of computer‐assisted surgery and navigation...
Background
The development of technology in robotic surgery is typically presented from a technical perspective. This study considers the user perspective as an input to the development of technology by exploring potential solutions within and beyond the field of robotic surgery.
Methods
Advanced technological solution concepts were selected based on a technology review and an ethnographic study...
Background
This study compared the surgical and urinary functional outcomes in patients with muscle‐invasive bladder cancer (MIBC) who underwent robot‐assisted radical cystectomy (RARC) followed by intracorporeal ileal neobladder reconstruction (ICNB) to those in patients who underwent minimum incision endoscopic radical cystectomy (MIE‐RC) followed by extracorporeal ileal neobladder reconstruction...
Background
Flexible endoscopes have become an important tool for the diagnosis and treatment of gastric cancer. However, there are several limitations to the use of endoscopes in rural areas, including their high cost, poor portability, and unstable platform.
Methods
This paper presents a novel low‐cost outer sheath for stomach screening. The sheath uses braided shape memory polymer (SMP) tubes...
