Background
The purpose of this study was to compare short‐ and long‐term outcomes of modified robot‐assisted duodenum‐preserving pancreatic head resection (RA‐DPPHR) versus robot‐assisted pancreaticoduodenectomy (RA‐PD).
Methods
Matched for age, sex, ASA classification, tumour size, history of abdominal surgery and pathological type, 34 patients undergoing RA‐DPPHR and 34 patients undergoing RA‐PD...
Background
Intramedullary nail (IMN) fixation improves functional outcomes for the diaphyseal fractures of long bones. However, locking the distal holes of the IMN is challenging. Although several navigation methods have been proposed, an intuitive, radiation‐free and accurate navigation method that does not suffer from problems of hand–eye coordination has not yet been described.
Methods
This...
Background
The cost‐effectiveness of robot‐assisted partial nephrectomy (RAPN) vs. the open procedure is not established.
Methods
We estimated in‐hospital complications and the cost of RAPN vs. open partial nephrectomy (OPN) using an economic model. Costs incurred both intraoperatively and in hospital were considered. US data were extracted from existing literature.
Results
Mean in‐hospital costs...
Background
The purpose of this study was to compare the clinical outcome of surgery using robot‐assisted posterior interbody fusion with that using freehand posterior interbody fusion in patients with degenerative spinal disease.
Methods
78 participants with degenerative spinal disease were randomly allocated (1:1) to the minimally invasive (MIS), posterior lumbar interbody fusion (Robot‐PLIF)...
Background
Robot‐assisted joint replacement surgery is becoming increasingly more common worldwide, therefore it is important to characterize and improve the bone‐cutting mechanics of surgical tools.
Methods
Linear coefficients relating cutting force and chip thickness were derived for a surgical spindle. The cutting coefficients were integrated into an analytical simulation which calculated cutting...
Background
We investigated the outcomes of morbidly obese patients after robotic beating heart totally endoscopic coronary artery bypass (BH‐TECAB).
Methods
This is a retrospective single center study. From July 2013 to December 2016, the outcomes of patients undergoing BH‐TECAB were reviewed.
Results
A total of 234 patients underwent BH‐TECAB (172 male, mean age 65.2 years). There were 43 morbidly...
Accurate planning transfer is a prerequisite for successful operative care. For different applications, diverse computer‐assisted systems have been developed and clinically evaluated. This paper presents the implementation and evaluation of a new modular concept. The approach is based on passive application specific kinematics that are semi‐automatically adjusted using a universal hand‐held computer...
Background
Surgical instruments greatly impact the performance of robot‐assisted minimally invasive surgery (RMIS) because they operate on tissues.
Methods
A snake‐like surgical instrument, designed with 4 degrees of freedom (DOFs), is proposed for RMIS. The DOFs are as follows: opening and closing motions of the forceps, rotation of the forceps and bi‐directional bending of the instrument. The...
Background
Surgical robot systems have been used in laparoendoscopic single‐site surgery (LESS) to improve patient outcomes. A magnetic anchoring surgical robot system for LESS can effectively extend the operation space.
Methods
A robot system based on visual servo control for LESS is proposed. It includes a magnetic anchoring robot and a control subsystem, in which an uncalibrated visual servo...
Background
Median Arcuate Ligament Syndrome (MALS) is a rare clinical condition.
Methods
Through the analysis of a case report and a review of the international literature, we examined whether robotic and laparoscopic MAL release are safe and feasible.
Results
Of 354 and 19 patients who underwent laparoscopic MAL release (LMALr) and robotic‐assisted MAL release (RMALr), respectively, conversion...
Robotic cardiac surgery was FDA‐approved in 2002 and since then several different procedures have been performed to facilitate a truly minimally invasive approach. The use of robotics in aortic valve surgery, however, is still in its infancy. In this article, we report our clinical experience and chronological development with robot‐assisted aortic valve surgery. This includes a description of how...
Background
The purpose of this study was to report minimum 2‐year outcomes and complications for robotic‐arm‐assisted total hip arthroplasty (THA).
Methods
Data were prospectively collected and retrospectively reviewed between June 2011 and April 2014. Inclusion criteria were primary robotic‐arm‐assisted THAs treating idiopathic osteoarthritis with ≥ 2‐year follow‐up. Demographics, operating time,...
Introduction
Since the introduction of wearable head‐up displays, there has been much interest in the surgical community adapting this technology into routine surgical practice.
Methods
We used the keywords augmented reality OR wearable device OR head‐up display AND surgery using PubMed, EBSCO, IEEE and SCOPUS databases. After exclusions, 74 published articles that evaluated the utility of wearable...
Background
Organ‐mounted robots address the problem of beating‐heart surgery by adhering to the heart, passively providing a platform that approaches zero relative motion. Because of the quasi‐periodic deformation of the heart due to heartbeat and respiration, registration must address not only spatial registration but also temporal registration.
Methods
Motion data were collected in the porcine...
Skull reconstruction is an important and challenging task in craniofacial surgery planning, forensic investigation and anthropological studies. Existing methods typically reconstruct approximating surfaces that regard corresponding points on the target skull as soft constraints, thus incurring non‐zero error even for non‐defective parts and high overall reconstruction error. This paper proposes a...
Background
The EndoMaster is a novel robot‐assisted surgical system originally designed for endoscopic resection of gastrointestinal polyps and tumours. It incorporates two robotic arms (a grasper and a probe for monopolar diathermy) into the end of a flexible endoscope, creating improved manoeuvrability, with two arms allowing for 9 degrees of movement and triangulation; this enables fine manipulation...
