We developed a simple, light, and cheap 3-D visualization device based on mixed reality that can be used by physicians to see preoperative radiological exams in a natural way. The system allows the user to see stereoscopic "augmented images," which are created by mixing 3-D virtual models of anatomies obtained by processing preoperative volumetric(More)
Minimally invasive surgery (MIS) has become very common in recent years, thanks to the many advantages it provides for patients. Since it is difficult for surgeons to learn and master this technique, several training methods and metrics have been proposed, both to improve the surgeon's abilities and also to assess his/her skills. This paper presents the use(More)
BACKGROUND It has recently been demonstrated that zinc oxide nanoparticles (ZnO NPs) induce death of cancerous cells whilst having no cytotoxic effect on normal cells. However, there are several issues which need to be resolved before translation of zinc oxide nanoparticles into medical use, including lack of suitable biocompatible dispersion protocols and(More)
— Some phases of laparoscopic interventions, such as suturing, require precise and dexterous movements that are difficult to perform by means of rigid instruments. Multi-DOF hand-held instruments and teleoperated systems have been developed to increase movement dexterity. In this paper, we present the design of a novel hand-held robotic instrument that can(More)
Boron nitride nanotubes (BNNTs) have generated considerable interest within the scientific community by virtue of their unique physical properties, which can be exploited in the biomedical field. In the present in vitro study, we investigated the interactions of poly-l-lysine-coated BNNTs with C2C12 cells, as a model of muscle cells, in terms of(More)
In the recent decades robotics and computer science have been gaining more and more relevance in all aspects of our lives. In surgery, for example, they gave birth to procedures, impossible to perform otherwise, like the tele-surgery or the nano-surgery. On this regard, these applied sciences already play an important role in assisting the surgeon both in(More)

An inchworm-like robot is a mobile robot that imitates the locomotion pattern of a natural inchworm. This type of robots usually consist of a series of interconnected actuating modules that can either deform in the direction of travel (extensors) or produce friction against the environment (grippers). The gait of an inchworm robot is a sequence of actuator(More)
BACKGROUND Using practical examples, this report aims to highlight the clinical value of patient-specific three-dimensional (3D) models, obtained segmenting multidetector computed tomography (MDCT) images, for preoperative planning in general surgery. METHODS In this study, segmentation and 3D model generation were performed using a semiautomatic tool(More)
BACKGROUND The STAR System (Ekymed SpA) is a novel multipurpose sponge developed for conventional manual laparoscopic surgery. MATERIALS AND METHODS Between December 2012 and December 2014, we successfully used the sponge in ten robot-assisted and ten direct manual laparoscopic operations to achieve haemostasis, for blunt dissections, for atraumatic(More)
