OBJECTIVES: To compare oncological outcomes and complication rates based on the Clavien classification between laparoscopic radical prostatectomies (LRP) and robot-assisted laparoscopic radical prostatectomies (RALP). MATERIAL AND METHODS: In a prospective quality registry clinical data were consecutively entered for 544 LRP and 1081 RALP patients operated from 2003 to the end of 2012. Complications within 90 days postoperatively were assessed according to the Clavien classification and compared between LRP and RALP patients...

Developing soft devices for invasive procedures bears great importance for human health. The softness and large strain actuation of responsive hydrogels promise the potential to fabricate soft devices, which can attach on and assist to the function of organs. The key challenges lie in the fabrication of soft devices with robust actuating ability and biocompatibility to the attached organ. This paper presents a solution that integrates the thermoresponsive hydrogel membrane with flexible electronics and silk scaffold into a balloon-like soft device...

Liquid crystal elastomers (LCEs) are soft materials capable of large, reversible shape changes, which may find potential application as artificial muscles, soft robots, and dynamic functional architectures. Here, the design and additive manufacturing of LCE actuators (LCEAs) with spatially programed nematic order that exhibit large, reversible, and repeatable contraction with high specific work capacity are reported. First, a photopolymerizable, solvent-free, main-chain LCE ink is created via aza-Michael addition with the appropriate viscoelastic properties for 3D printing...

Jeffery A Hall, Hui Ming Khoo
BACKGROUND: Stereoelectroencephalography has been in regular use at the Montreal Neurological Institute since 1972. The technique has been in constant evolution to incorporate advances in materials, imaging, and robotics technology. MRI-compatible electrodes were introduced in 2007 and robotics in 2011. Here we report on the technique, safety, and advantages of our current method of stereoelectroencephalography implantation. METHODS: We retrospectively reviewed all patients who underwent stereoelectroencephalography by the senior author...

Hae-Jin Kim, Anish Thukral, Cunjiang Yu
There is a growing interest in developing stretchable strain sensors to quantify the large mechanical deformation and strain associated with the activities for a wide range of species, such as humans, machines, and robots. Here, we report a novel stretchable strain sensor entirely in a rubber format by using a solution processed rubbery semiconductor as the sensing material to achieve high sensitivity, large mechanical strain tolerance, hysteresis-less and highly linear responses. Specifically, the rubbery semiconductor exploits π-π stacked poly(3-hexylthiophene-2,5-diyl) nanofibrils (P3HT-NFs) percolated in silicone elastomer of polydimethylsiloxane (PDMS) to yield semiconducting nanocomposite with a large mechanical stretchability, although P3HT is a well-known nonstretchable semiconductor...

Accurate force simulation is essential to haptic simulators for surgical training. Factors such as tissue inhomogeneity pose unique challenges for simulating needle forces. To aid in the development of haptic needle insertion simulators, a handheld force sensing syringe was created to measure the motion and forces of needle insertions. Five needle insertions were performed into the neck of a cadaver using the force sensing syringe. Based on these measurements a piecewise exponential needle force characterization, was implemented into a haptic central venous catheterization (CVC) simulator...

This paper reports the design, development, and initial evaluation of a robotic laparoscopic clipping tool for single manipulator wound closure and anastomosis (tubular reconnection). The tool deploys biodegradable clips and clasps with the goal of (i) integrating grasping and suturing into a single device for single hand or manipulator use, (ii) applying the equivalent of interrupted sutures without the need of managing suture thread, and (iii) allowing for full six degrees-of-freedom (DOFs) laparoscopic control when mounted on a robot arm...

BACKGROUND Robot-assisted radical prostatectomy (RARP) is increasingly used worldwide, but comparisons of perioperative, functional, and oncologic outcomes among RARP, laparoscopic radical prostatectomy (LRP), and open radical prostatectomy (ORP) remain inconsistent. MATERIAL AND METHODS Systematic literature searches were conducted using EMBASE, PubMed, the Cochrane Library, CNKI, and Science Direct/Elsevier up to April 2017. A meta-analysis was conducted using Review Manager and Stata software. RESULTS We included 33 studies...

Robotics is continuously being integrated in animal behaviour studies to create customizable, controllable, and repeatable stimuli. However, few systems have capitalized on recent breakthroughs in computer vision and real-time control to enable a two-way interaction between the animal and the robot. Here, we present a "closed-loop control" system to investigate the behaviour of zebrafish, a popular animal model in preclinical studies. The system allows for actuating a biologically-inspired 3D-printed replica in a 3D workspace, in response to the behaviour of a zebrafish...

The incidence of endometrial cancer (EC) is steadily increasing due in large part to an aging world population and rise in rates of obesity. Patients with obesity and advancing age can be seen as vulnerable populations, as they are both often subject to physician bias regarding surgical choices and assumptions regarding long-term outcomes. As we operate on an older and/or obese patient population, it is increasingly important that we adopt peri-operative management strategies and surgical techniques to best serve this complex patient population...

Despite the benefits introduced by robotic systems in abdominal Minimally Invasive Surgery (MIS), major complications can still affect the outcome of the procedure, such as intra-operative bleeding. One of the causes is attributed to accidental damages to arteries or veins by the surgical tools, and some of the possible risk factors are related to the lack of sub-surface visibilty. Assistive tools guiding the surgical gestures to prevent these kind of injuries would represent a relevant step towards safer clinical procedures...

BACKGROUND: This study presents oncologic outcomes after transoral robotic surgery (TORS) ± adjuvant therapy for oropharyngeal squamous cell carcinoma (SCC). METHODS: Three hundred fourteen patients undergoing TORS ± adjuvant therapy for oropharyngeal SCC from May 1, 2007, to May 31, 2015, are analyzed. RESULTS: Median follow-up was 3.3 years (interquartile range [IQR] 1.8-5.3 years; range 1 day to 9.3 years). Estimated locoregional recurrence-free survival, distant metastasis-free survival (DMFS), overall survival (OS), and cancer-specific survival (CSS) rates (95% confidence interval [CI] number still at risk) at 5 years after surgery were 92% (88-95; 92), 90% (86-94; 92), 86% (82-92; 98), and 94% (91-97; 98), respectively...

Eagle's syndrome is characterised by focal pain in the tonsillar fossa on wide mouth opening or head rotation and various accompanying symptoms. While the syndrome is difficult to diagnose, shortening the styloid process via a transoral or transcervical surgical approach has been shown to be the most effective treatment. The aim of this article was to document our experience with a transoral robotic approach to treat Eagle's syndrome and to present the outcomes of four patients. We reviewed the cases of four patients with Eagle's syndrome who underwent transoral robotic surgery (TORS)...

INTRODUCTION: Despite advances in treatment, notably in systemic therapy, the prognosis of pancreatic adenocarcinoma (PADC) remains dismal. Stereotactic body radiotherapy (SBRT) is an emerging tool in the complex management of PADC. We review outcomes of SBRT for PADC at our institution. METHODS: We reviewed patients treated with SBRT for either unresectable PADC or locally recurrent PADC after surgery. Treatment was delivered using a robotic radiosurgery system with respiratory tracking...

BACKGROUND: Partial nephrectomy is widely used for surgical management of small renal masses. Use of robotic (RPN) versus open partial nephrectomy (OPN) among various populations is not well characterized. OBJECTIVE: To analyze trends in utilization of RPN and disparities that may be associated with this procedure for management of cT1 renal masses in the USA. DESIGN, SETTING, AND PARTICIPANTS: Patients who underwent RPN or OPN for clinical stage T1N0M0 renal masses in the USA from 2010 to 2013 were identified in the National Cancer Data Base...
