567e Breast augmentation is the most common aesthetic surgical procedure, with more than 300,000 performed in 2011.1 Choices of incisions, pocket plane, and implant characteristics, including shape, texture, filler, and volume, constitute the key decisions in surgical planning. Thoughtful analysis of physical characteristics and patient participation in the process are the most important factor...

Surgery is one of the fields where robots have been introduced due to their positioning accuracy which exceed the human capabilities. Parallel robots offer higher stiffness and smaller mobile mass than serial ones, thus allowing faster and more precise manipulations that fit medical applications. In the paper is presented the modeling and simulation of a new parallel robot, based on an innovati...

Background Considerable resources have been invested in both low- and high-fidelity simulators in surgical training. The purpose of this study was to investigate if the Fundamentals of Laparoscopic Surgery (FLS, low-fidelity box trainer) and LapVR (high-fidelity virtual reality) training systems correlate with operative performance on the Global Operative Assessment of Laparoscopic Skills (GOAL...

Endoscopic surgery as a less invasive method of surgery, is more di cult to perform. The associated problems are visual issues, hand/tool's movement, and force/tactile sensing. To overcome some of these di culties, in this paper new design concepts are reviewed and proposed such as tools with exible stem, suturing device, positioning stand, and robotic ende ectors for master-slave systems.

Abstracz This paper addresses the modeling and control of a compliant micromanipulator for use in such$elh as microsurgery, telesurgery, and microassembly, The unique flexure-based manipulator utilizes revolute flexure joints in achieving well-behaved kinematic characteristics, without the backlash and stick-slip phenomena that would otherwise impede precision control. A mathematical model of t...

jeremy shiffman’s editorial appropriately calls on making all forms of power more apparent and accountable, notably productive power derived from expertise and claims to moral authority. this commentary argues that relationships based on productive power can be especially difficult to reveal in global health policy because of embedded notions about the nature of power and politics. yet, it is e...

OBJECTIVES Surgical simulation has been shown to enhance the training of general surgery residents. Since catheter-based techniques have become an important part of the vascular surgeon's armamentarium, we explored whether simulation might impact the acquisition of catheter skills by surgical residents. METHODS Twenty general surgery residents received didactic training in the techniques of c...

Due to their fast response, high accuracy and non-friction force, piezo-actuators have been widely employed in multiple degree-of-freedom (DOF) stages for various nano-positioning applications. The use of flexible hinges in these piezo-actuator-driven stages allows the elimination of the influence of friction and backlash clearance, as observed in other configurations; meanwhile it also causes ...

Background and purpose: Obesity is a major global health problem today and the only evidence-based method leading to a long-lasting weight reduction is bariatric surgery. Physical activity improves health, decreases the incidence of several diseases and may influence weight loss outcome after bariatric surgery. Knowledge regarding how patients experience physical activity after bariatric surger...

introduction : the aim of this study is to define the trend of the orthodontists and the surgeons in the borderline class iii patients and assess their satisfaction after the surgery. materials and methods : the study population consisted of 31 patients (16 female and 15 male) with the average age of 21 years, whose final occlusion 2 months after the surgery was perfect. the amount of reverse o...
