Because of the remarkable developments in robotics in recent years, technological convergence has been active in this area. We focused on finding patterns of convergence within robot technology using network analysis of patents in both the USPTO and KIPO. To identify the variables that affect convergence, we used quadratic assignment procedures (QAP). From our analysis, we observed the patent network ecology related to convergence and found technologies that have great potential to converge with other robotics technologies...

PURPOSE OF REVIEW: Although open ureteral reimplantation remains the gold standard for surgical correction of vesicoureteral reflux (VUR), robotic-assisted laparoscopic ureteral reimplantation (RALUR) holds promise and is becoming more widely utilized. The present article outlines primary operative techniques for RALUR, summarizes the current literature with respect to surgical outcomes and costs, and discusses early applications of RALUR to complex and reoperative cases. RECENT FINDINGS: Intravesical and extravesical techniques for RALUR have been described...

Visual odometry estimates the ego-motion of an agent (e.g., vehicle and robot) using image information and is a key component for autonomous vehicles and robotics. This paper proposes a robust and precise method for estimating the 6-DoF ego-motion, using a stereo rig with optical flow analysis. An objective function fitted with a set of feature points is created by establishing the mathematical relationship between optical flow, depth and camera ego-motion parameters through the camera's 3-dimensional motion and planar imaging model...

PURPOSE: Youth with disabilities are under-represented in science, technology, engineering, and math (STEM) in school and in the workforce. One encouraging approach to engage youth's interest in STEM is through robotics; however, such programs are mostly for typically developing youth. The purpose of this study was to understand the development and implementation of an adapted robotics program for children and youth with disabilities and their experiences within it. METHOD: Our mixed methods pilot study (pre- and post-workshop surveys, observations, and interviews) involved 41 participants including: 18 youth (aged 6-13), 12 parents and 11 key informants...

PURPOSE: The integration of sufficient cardiovascular stress into robot-assisted gait (RAG) training could combine the benefits of both RAG and aerobic training. The aim was to summarize literature data on the immediate effects of RAG compared to walking without robot-assistance on metabolic-, cardiorespiratory- and fatigue-related parameters. METHODS: PubMed and Web of Science were searched for eligible articles till February 2016. Means, SDs and significance values were extracted...

CONTEXT: Recently, locomotor training with robotic assistance has been found effective in treating spinal cord injury (SCI). Our case report examined locomotor training using the robotic suit hybrid assistive limb (HAL) in a patient with complete C4 quadriplegia due to chronic SCI. This is the first report examining HAL in complete C4 quadriplegia. FINDINGS: The patient was a 19-year-old man who dislocated C3/4 during judo 4 years previously. Following the injury, he underwent C3/4 posterior spinal fusion but remained paralyzed despite rehabilitation...

BACKGROUND: Although effective, duodenal switch can be a complicated and time-consuming operation for surgeons. PURPOSE: The purpose of this article is to present our technique of biliopancreatic diversion and vertical sleeve gastrectomy, creating a 150-cm common channel and a 100-cm alimentary limb. MATERIAL AND METHODS: A robot-assisted technique was utilized in creating a biliopancreatic diversion and vertical sleeve gastrectomy. RESULTS: Laparoscopy was used for marking stitches and then the robot was docked...

The aim of this paper was to evaluate the current technology and designs of flexible ureterorenoscopes. We will review contemporary fiberoptic and digital ureteroscopes, including a discussion on ureteroscope damage and repair, and lastly present the projected future of flexible ureterorenoscopy. Ureterorenoscopy has evolved dramatically over the past several decades, which has led to landscape reshaping of stone disease treatment and upper tract pathology. Advancements in tip control, miniaturization of scopes, introduction of a digital chip on the tip, disposable devices to augment surgery, surgical experience/familiarity and most recently single use scopes are all independent factors that have increased flexible ureterorenoscopy adoption and success...

Open ureterolithotomy and pyelolithotomy used to be first line therapy for treating kidney and ureteral stones. With the advent of shockwave lithotripsy, open stone surgery became less prevalent, but once ureteroscopy became more prevalent, open stone surgery became all but extinct. Advances in smaller, more flexible endoscopes and improvements in intracorporeal lithotripters, ureteroscopy has become a mainstay of therapy for kidney stones. The holmium:YAG laser can be utilized through flexible instruments and fragments any stone no matter what it is composed of...

INTRODUCTION: With healthcare reform, cost and patient satisfaction will directly affect hospital reimbursement. We present data on same day discharge (SDD) for patients who underwent robot assisted laparoscopic radical prostatectomy (RALP). METHODS: Patient data were gathered in an IRB approved database. In April 2015, surgeon (SJ) began SDD. The SDD protocol for RALP includes multimodal anesthesia/analgesia and extended recovery. Interim analysis revealed that government insurance (CMS) refused hospital reimbursement for SDD...

BACKGROUND: Open posterior spinal procedures involve extensive soft tissue disruption, increased hospital length of stay, and disfiguring scars. Our aim was to demonstrate the feasibility of using robotic-assistance for minimally invasive exposure of the posterolateral spine with and without carbon dioxide (CO2 ) insufflation. METHODS: Sheep specimens underwent minimally invasive subperiosteal dissection of the spine during three trials. The da Vinci S Surgical system was used for access with and without working space support via CO2 insufflation...

The concept of complete mesocolic excision and central vascular ligation for colonic cancer has been recently introduced. The paper describes a technique of right-sided complete mesocolic excision and intracorporeal anastomosis by using a single-port robotic approach with an additional conventional robotic port. We performed a single-port plus an additional port robotic surgery using the Da Vinci Single-Site platform via the Pfannenstiel incision and the wristed robotic instruments via an additional robotic port in the left lower quadrant...

INTRODUCTION: The aim of this study was evaluating if the presence of a humanoid robot could improve the efficacy of a game-based, nutritional education intervention. STUDY DESIGN: This was a controlled, school-based pilot intervention carried out on fourth-grade school children (8-10 years old). A total of 112 children underwent a game-based nutritional educational lesson on the importance of carbohydrates. For one group (n = 58), the lesson was carried out by a nutritional educator, the Master of Taste (MT), whereas for another group, (n = 54) the Master of Taste was supported by a humanoid robot (MT + NAO)...

INTRODUCTION: Knee muscles are commonly labelled as flexors or extensors and aptly stabilize the knee against sagittal plane loads. However, how these muscles stabilize the knee against adduction-abduction and rotational loads remains unclear. Our study sought to: (1) classify muscle roles as they relate to joint stability by quantifying the relationship between individual muscle activation patterns and internal net joint moments in all three loading planes, and (2) determine if these roles change with increasing force levels...

The aim of this study was to explore the application of the IROMEC (Interactive social RObotic Mediators as Companions) robot to support play for children with severe physical disabilities in rehabilitation and special education. Within a 2-month pilot study, physically disabled children with a developmental age between 2 and 8 years participated in sessions with the robot. A combination of qualitative and quantitative outcome measures was used to collect data on aspects of feasibility, usability, barriers for the child as well as the therapist and an indication of the effects on playfulness and the achievement of therapeutic and educational goals...
