The lack of haptic feedback in robotics-assisted surgery can result tissue damage or accidental tool-tissue hits. This paper focuses on exploring the effect via direct force reflection and visual presentation magnitudes performance during suturing minimally invasive (RAMIS). For this purpose, a haptics-enabled dual-arm master-slave teleoperation system capable measuring interaction forces all seven Degrees-of-Freedom (DOFs) was used. Two tasks, puncturing knot-tightening, were chosen to...

Minimally invasive surgery (MIS) has been limited from its inception by insufficient haptic feedback to surgeons. To address this, various force sensing methods have developed that can provide information about tool-tissue interaction forces. However, the results unreliable in most of these studies, since there are many sources error and uncertainty acquisition method. Furthermore, none devices described literature be fully cleaned or sterilized for use surgery. a sterilizable needle-driver...

Smart textile sensors have been gaining popularity as alternative methods for the continuous monitoring of human motion. Multiple fabrication these proposed, but simpler ones include stitching or embroidering conductive thread onto an elastic fabric to create a strain sensor. Although multiple studies demonstrated efficacy using technique, there is almost little no information regarding embroidery method. In this paper, design guide embroidered resistive sensor presented. All required steps...

Minimally invasive surgery (MIS) is carried out using long, narrow instruments and significantly reduces trauma to the body, postoperative pain, recovery time. Unfortunately, restricted access conditions, limited instrument motion, degraded sense of touch inherent in MIS result new perceptual-motor relationships, which are unfamiliar surgeon require training overcome. Current methods do not adequately address needs surgeons interested acquiring these skills. Although a significant amount...

Distribution of species Echinococcus (E. multilocularis, E. granulosus, oligarthrus, and patogonicus) was reviewed with special reference to the American continent. Human domestic animal populations susceptible echinococcosis are strikingly different in distribution. In Americas, human disease is most prevalent areas intensive sheep husbandry, but pattern occurrence hydatidosis may be altered as changes structure industry introduced developing countries. Recently published information...

Current treatments for parkinsonian tremor, such as medication and brain surgery, have shown varying levels of effectiveness carry the risk significant side effects complications. Studies on wearable tremor suppression devices positive results in use mechanical electrical management upper limbs. Wearable technology is a promising solution patients who do not respond to present severe enough symptoms undergo surgery. Available are mainly elbow wrist tremor. Devices finger been developed...

Abstract Background Localizing lung tumours during minimally invasive surgery is difficult, since restricted access precludes manual palpation and pre‐operative imaging cannot map directly to the intra‐operative lung. This study analyses force‐sensing performance that would allow an instrumented kinaesthetic probe localize based on stiffness variations of parenchyma. Methods Agar injected into ex vivo porcine lungs produced a model approximating commonly encountered tumours....

The complexity of minimally invasive surgery (MIS) requires that trainees practice MIS skills in numerous training sessions. goal these sessions is to learn how move the instruments smoothly without damaging surrounding tissue and achieving operative tasks with accuracy. In order enhance efficiency sessions, proficiency should be assessed using an objective assessment method. Several performance metrics have been proposed analyzed for tasks. differentiation various levels expertise limited...

Recent progress in wearable technology has made tremor suppression devices (WTSDs) for Parkinson's patients a potentially viable alternative solution management. So far, contrast to wrist and elbow tremor, finger tremors have not been studied depth despite the huge impact that they on patient's daily life. In addition, more evidence found showing performance of current estimators may be limited by their model order due multiple harmonics present tremor. The aim this paper is characterize...

The study of the mechanical characteristics tremor for patients suffering from Parkinson's disease (PD) is an important first step to design suppression orthoses. So far, researchers have interpreted in both time and frequency domains. A number devices been developed on basis these interpretations tremor. However, most studies only focused at wrist elbow, neglected finger despite huge impact that it has a patient's daily life. aim present was determine tremor, which may be used provide...

Wearable suppression devices (WTSD) provide an alternative approach, however, in the fingers has been given as much attention elbow and wrist. Therefore, objective this study is design a wearable glove that can suppress simultaneously, but independently, multiple hand joints without restricting user's voluntary motion. Methods: A WTSD was designed for managing index finger...
