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)
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)
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)
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)
A technique of orthotopic liver transplantation using a segmental graft from living donors was developed in the dog. Male mongrel dogs weighing 25-30 kg were used as donors and 10-15 kg as recipients. The donor operation consists of harvesting the left lobe of the liver (left medial and left lateral segments) with the left branches of the portal vein,(More)
