Background
Outcomes after robotic distal pancreatectomy with spleen preservation (RDP‐SP) by the Warshaw technique and with splenectomy (RDP‐S) were compared.
Methods
All the data for patients undergoing robotic distal pancreatectomy (RDP) were prospectively collected.
Results
A total of 66 patients were included, with 33 in each group. The console time was significantly shorter in the RDP‐SP...
Background: The limited field of view of the X‐ray image intensifier makes it difficult to cover a large target area with a single X‐ray image. X‐ray image stitching techniques have been proposed to produce a panoramic X‐ray image.
Methods: This paper presents an efficient intensity‐based X‐ray image stitcher, which does not rely on accurate C‐arm motion control or auxiliary devices and hence is ready...
Background
Full‐thickness local excision (FTLE) for rectal cancer showing clinical complete remission (cCR) after neoadjuvant chemoradiation therapy (NCRT) is associated with good oncological results. The purpose of this study was to report the results of robotic transanal minimally invasive surgery for such patients.
Methods
Patients were treated with a 5‐fluorouracil‐based NCRT regimen. The determination...
Purpose
The purpose of this study was to investigate the safety and efficacy of the combination of robot‐assisted percutaneous screw placement and pelvic internal fixator (INFIX) for minimally invasive treatment of unstable anterior and posterior pelvic ring injuries.
Methods
From September 2016 to June 2017, twenty‐four patients with unstable anterior and posterior pelvic ring injuries were treated...
Background
Virtual cutting of deformable objects has been a research topic for more than a decade and has been used in many areas, especially in surgery simulation.
Methods
We refer to the relevant literature and briefly describe the related research. The virtual cutting method is introduced, and we discuss the benefits and limitations of these methods and explore possible research directions....
Background
Applying transrectal ultrasound to robot‐assisted laparoscopic radical prostatectomy has attracted attention in recent years, and it is considered as a proper method to provide real‐time subsurface anatomic features. A precise registration between the ultrasound equipment and robotic surgical system is necessary, which usually requires a fast and accurate recognition of the registration...
Background
We previously developed an image‐guided navigation system (IG‐NS) using augmented reality technology for hepatobiliary and pancreatic (HBP) surgery. This system superimposed a 3D model onto a stereoscope‐captured surgical field (i.e., the scope method). Unfortunately, this method requires an expensive stereoscope, surgeons have to shift their eyesight away from the surgical field, and...
Background
Tunnel misplacement is a common cause of failed anterior cruciate ligament (ACL) reconstruction. In this study, the accuracy of the femoral tunnel position was evaluated in robot‐assisted ACL reconstruction using a magnetic resonance imaging (MRI)‐based navigation system. We hypothesized that a difference of less than 2 mm between the planned femoral tunnel position and the created one...
Background
Natural orifice transluminal endoscopic (NOTES) and single incisional laparoscopic surgeries (SILS) have been gaining importance over the last two decades. Due to improper instrumentation, small workspace and the imperceptibility of body structures, suturing and knot‐tying are difficult to perform in both.
Methods
An intracorporeal suture‐passing device with two manipulator arms is proposed...
Background
Its relatively low incidence and its surgical complexity mean that a standardized technique for left colectomy has not yet been established for splenic flexure and descending colon cancer (SF‐DCC).
Methods
Seventy‐three patients (robot‐assisted left colectomy with complete mesocolectomy [R‐LCCM], n = 20; laparoscopic left colectomy with complete mesocolectomy [L‐LCCM], n = 53) with SF‐DCC...
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...
