A novel metamorphic anthropomorphic hand is for the first time introduced in this paper. This robotic hand has a reconfigurable palm that generates changeable topology and augments dexterity and versatility of the hand. Structure design of the robotic hand is presented and based on mechanism decomposition kinematics of the metamorphic anthropomorphic hand is characterized with closed-form solut...

BACKGROUND To ensure safe performance in robotic surgery, the Minimal Invasive Surgery Center (MISC) is composed of the anesthesiology department, five surgery departments and co-medical staff in our institution. The objective of this study was to evaluate the outcomes of different types of robotic surgeries for cancer treatment (n = 326) from different surgery departments in the MISC. METHOD...

Purpose: To compare outcomes of robotic adrenalectomy with conventional laparoscopic adrenalectomy. Materials and Methods: This retrospective study included 63 patients who underwent robotic or laparoscopic adrenalectomy between March 2005 and April 2016, with all operations performed using a transperitoneal approach. Outcomes were compared in the 29 patients who underwent robotic adrenalectomy...

BACKGROUND AND PURPOSE Robotic devices that provide passive guidance and stabilization of the legs and trunk during treadmill stepping may increase the delivery of locomotor training to subjects with neurological injury. Lower-extremity guidance also may reduce voluntary muscle activity as compared with compliant assistance provided by therapists. The purpose of this study was to investigate di...

BACKGROUND Resection of malignancies in the head and uncinate process of the pancreas (Whipple procedure) using a robotic approach is emerging as a surgical option. Although several case series of the robotic Whipple procedure have been reported, detailed descriptions of operative techniques and a clear pathway for adopting this technology are lacking. METHODS We present a focused review of t...

PURPOSE OF REVIEW To present the recent advances in needle guidance and robotic ultrasound technology which are used for prostate cancer (PCa) diagnosis and management. RECENT FINDINGS Prostate biopsy technology has remained relatively unchanged. Improved needle localization and precision would allow for better management of this common disease. Robotic ultrasound and needle guidance is one s...

Robotic-assisted microsurgery can be utilized for either intracorporal or extracorporeal surgical procedures. Three-dimensional high-definition magnification, a stable ergonomic platform, elimination of physiologic tremor, and motion scaling make the robotic platform attractive for microsurgeons for complex procedures. Additionally, robotic assistance enables the microsurgeon to take microsurge...

Robotic radical prostatectomy is a new innovation in the surgical treatment of prostate cancer. The technique is continuously evolving. In this article we demonstrate The Ohio State University technique for robotic radical prostatectomy. Robotic radical prostatectomy is performed using the da Vinci surgical system. The video demonstrates each step of the surgical procedure. Preliminary results ...

In this paper motion analysis on a winding stair-climbing is investigated using our proposed rotational arm type of robotic wheelchair. For now, the robotic wheelchair is operated in an open mode to climb winding stairs by a dynamic turning, therefore, the dynamics model is required to ensure a passenger’s safety. Equations of motion based on the skid-steering analysis are developed for the tra...

PURPOSE To compare the relative merits among robotic surgery, laparoscopy, and laparotomy for patients with endometrial cancer by conducting a meta-analysis. METHODS The MEDLINE, Embase, PubMed, Web of Science, and Cochrane Library databases were searched. Studies clearly documenting a comparison between robotic surgery and laparoscopy or between robotic surgery and laparotomy for endometrial...
