BackgroundForce feedback in robotic minimally invasive surgery allows the human operator to manipulate tissues as if his/her hands were in contact with the patient organs. A force sensor mounted on the probe raises problems with sterilization of the overall surgical tool. Also, the use of off‐axis gauges introduces a moment that increases the friction force on the bearing, which can easily mask off...
BackgroundMedical simulators with vision and haptic feedback techniques offer a cost‐effective and efficient alternative to the traditional medical trainings. They have been used to train doctors in many specialties of medicine, allowing tasks to be practised in a safe and repetitive manner. This paper describes a virtual‐reality (VR) system which will help to influence surgeons' learning curves in...
BackgroundBariatric laparoscopic surgery has been shown to lead to sustainable weight‐loss in obese individuals. Robotic‐assisted laparoscopic surgery is proposed as the next major evolution in minimally invasive surgery. This study systematically reviews the literature regarding the feasibility and safety of robotic‐assisted bariatric surgery in obese patients.
MethodsA comprehensive search of electronic...
BackgroundCentral pancreatectomy (CP) is increasingly being used to treat selected lesions of the central pancreatic segment. A step‐by‐step technique for robotic CP is described and a literature review provided for this minimally invasive approach.
MethodsA 55‐year‐old woman was referred to the authors' center for the treatment of a single 4 cm lesion located at the proximal part of the pancreatic...
BackgroundTransurethral resection of the prostate (TURP) is a challenging operation for residents with limited endoscopic experience. A number of virtual TURP simulators have been validated in the past. This study is the first description and preliminary evaluation of a non‐virtual, low‐cost TURP trainer as a teaching tool for residents in urology.
MethodsDr K. Forke's prostatic resection trainer...
BackgroundThis paper presents a novel tactile sensing robot designed to characterize the viscoelastic behaviour of breast tissue during clinical breast examination (CBE). The robot, named the ‘robotic tactile breast mass identifier’ (Robo‐Tac‐BMI), mainly consists of an indentation probe controlled by a robotic system and a visualization interface to manipulate the end‐effector. Major high order mechanical...
BackgroundCompared with conventional minimally invasive surgery and open surgery, robotic‐assisted minimally invasive surgery can overcome or eliminate drawbacks caused by operator restrictions, motion limitation by the trocar and the image system, such as fatigue, trembling, low precision, constrained degree‐of‐freedom, poor hand–eye coordination and restricted surgical vision. In this paper, a novel...
BackgroundTraditional endoscopy may cause tissue trauma and discomfort to patients because of the use of relatively long and semi‐rigid scopes.
MethodsA wireless robotic endoscope has been designed based on minimally invasive locomotion and wireless techniques for energy, monitoring, and telecontrol.
ResultsThe robotic endoscope can move forward or backward effectively in a smooth synthetic glass...
BackgroundMR elastography (MRE) is an emerging technique for tumor diagnosis. MRE actuation devices require precise mechanical design and radiofrequency engineering to achieve the required mechanical vibration performance and MR compatibility.
MethodA method of designing a general‐purpose, compact and inexpensive MRE actuator is presented. It comprises piezoelectric bimorphs arranged in a resonant...
BackgroundBased on the background of minimally invasive surgery and applications of medical robots, a vascular interventional robotic system has been developed that can be used in the field of vascular intervention.
MethodsThe robotic system comprises a propulsion system, an image navigation system and a virtual surgery training system. Integration of the three systems constitutes a vascular intervention...
BackgroundSince the introduction of robotics, relatively few series have been published evaluating its role for right colectomy. The aim of this study was to report our preliminary experience with totally robotic right colectomy (TRRC).
MethodsBetween 2009 and 2010 we performed three TRRCs, using a hand‐sewn intracorporeal anastomosis. Data were retrospectively reviewed.
ResultsTwo women and one...
BackgroundAlthough the use of robotic laparoscopic surgery has increased in popularity, training protocols for gaining proficiency in robotic surgical skills are not well established. The purpose of this study was to examine a fundamental training program that provides an effective approach to evaluate and improve robotic surgical skills performance using the da Vinci™ Surgical System.
MethodsFifteen...
BackgroundFemoroacetabular impingement (FAI) is increasingly recognized as a potential cause of hip osteoarthritis. A system capable of pre‐operatively simulating hip range of motion (ROM) by given surface models from either healthy or FAI diseased bone is desirable.
MethodsAn impingement detection system using bounding sphere hierarchies was first developed. Both precision and accuracy of the impingement...
ObjectiveTo compare the surgical and pathological outcomes of patients with right‐sided colon cancers operated on by means of open and robotic surgery with extracorporeal anastomosis.
MethodsThirty‐three consecutive patients who underwent robotic right hemicolectomy due to right‐sided colon cancer were retrospectively well matched with 102 patients operated on by the open approach. Data were included...
BackgroundOptical assistance in laparoscopic surgery is essential for an optimal procedure. Unlike conventional surgery, it requires new systems to reduce spatial location time, navigation and cleanliness without compromising surgical quality. This article shows the kinematic analysis of a new bio‐mechatronic design to assist laparoscopic visual perspective in real time, either during training or...
