BackgroundSingle‐access laparoscopic splenectomy can offer patients some advantages. It has many difficulties, such as instrument clashing, lack of triangulation, odd angles and lack of space. The Da Vinci Single‐Site® robotic surgery platform could decrease these difficulties. We present a case of single‐access robotic splenectomy using this device.
MethodsA 37 year‐old female with idiopathic thrombocytopenic...
BackgroundAccurate needle placement is crucial for the success of percutaneous radiological needle interventions. We compared three guiding methods using an optical‐based navigation system: freehand, using a stereotactic aiming device and active depth control, and using a stereotactic aiming device and passive depth control.
MethodsFor each method, 25 punctures were performed on a non‐rigid phantom...
BackgroundTransoral laser microsurgery (TLM) is a mature approach to supraglottic cancer, while transoral robotic surgery (TORS) is emerging. The present study compared these approaches.
MethodsThe first 10 patients (2002–2005) given TLM were compared with the first 10 (2007–2011) given TORS for cT1‐3 cN0‐cN2c supraglottic cancer.
ResultsA feeding tube was used in four TLM and seven TORS patients...
BackgroundRobotic telemanipulation systems have emerged as facilitating tools that enhance minimally invasive cardiac surgery.The purpose of this study was to evaluate graft patency by a combination of invasive and non‐invasive coronary angiography methods in robotic‐assisted coronary artery surgery(CABG) for optimal quality control.
MethodsBetween April 2004 and February 2012, patients who had robotic‐assisted...
BackgroundPerforming minimally invasive interventions under direct MRI guidance offers significant advantages. Required accessibility to the patient inside the MRI scanner is fairly limited, and employment of robotic assistance has been proposed. The development of MR‐compatible robotic systems entails engineering challenges related to geometric constraints and the magnetic nature of the scanning...
BackgroundRobotic‐assisted minimally invasive surgery systems not only have the advantages of traditional laparoscopic instruments but also have other important advantages, including restoring the surgeon's hand–eye coordination and improving the surgeon's precision by filtering hand tremors. Unfortunately, these benefits have come at the expense of the surgeon's ability to feel. Various solutions...
BackgroundVR‐based surgery simulation provides a cost‐effective and efficient method to train novices. In this study, a virtual training system for maxillofacial surgery (VR‐MFS), which aims mainly at the simulation of operations on mandible and maxilla, was developed and demonstrated.
MethodsThe virtual models of the anatomic structures were reconstructed from CT data, and the virtual instruments...
BackgroundAccurate patient to image registration is the core for successful image‐guided neurosurgery. While skin adhesive markers (SMs) are widely used in point‐matching registration, a proper implementation of anatomical landmarks (ALs) may overcome the inconvenience brought by the use of SMs.
MethodsUsing nine ALs, a set of three configurations of different combinations of them is proposed. These...
BackgroundA prototype magnetic resonance imaging (MRI)‐compatible positioning device that navigates a high intensity focused ultrasound (HIFU) transducer is presented. The positioning device has three user‐controlled degrees of freedom that allow access to brain targets using a lateral coupling approach. The positioning device can be used for the treatment of brain cancer (thermal mode ultrasound)...
BackgroundProximal tibial open wedge osteotomy (PTO) is a corrective operation used in the surgery of lower extremities and is applied to patients with varus deformities for sufficient correction. The aim of the study was to evaluate whether the PTO can achieve decreased stress‐bearing on the tibia and tarsal bones in addition to correcting the mechanical axis of the lower limb in patients with tibia...
BackgroundThe expanding use of robotic technology has introduced a requirement to incorporate this technology into traditional training programs. The goal of this study is to demonstrate the safe introduction of the robotic surgical system during residency programs, using robotic cholecystectomy as the basic procedure.
MethodsA total of 170 patients who underwent robotic cholecystectomy at a tertiary...
BackgroundOne of the main sources of error in commercial surgical navigation systems is the tracking of surgical tools. Mainstream systems typically use optical or electromagnetic tracking technologies, which exhibit accuracies of the order of 1 mm. The objective of this study was to introduce a lightweight high‐precision passive coordinate measurement arm into an augmented reality‐based surgical...
BackgroundThe validation of patient‐specific surgical guides (PSGs) by their design and the comparison of planned and actual PSG setting in total hip arthroplasty (THA) have not previously been reported.
MethodsThe errors between preoperative planning and computed tomography (CT)‐based PSG setting (E1), and between preoperative planning and implantation (E2) were evaluated using CT in 16 fresh cadaveric...
BackgroundThe management of advanced cervical cancer is challenging. The administration of neoadjuvant chemotherapy (NACT) followed by radical hysterectomy has proved to be safe in selected cases. Nevertheless, data on the use of minimally invasive surgery is lacking with this clinical application.
MethodsA 31 year‐old woman was diagnosed with a FIGO stage IIIB squamous cell cervical carcinoma. During...
BackgroundIntervention on small targets in the lung is difficult, leading our team to develop a highly accurate respiratory correlated image guided surgery (RCIGS) system.
MethodsSimulated point source targets were implanted into ex vivo porcine and human cadaver lungs attached to a ventilator. The RCIGS system was utilized to guide intervention in the presence of respiratory motion using a commercially...
BackgroundThe study was performed to establish a level of practice needed for newly‐trained residents to maintain robotic surgical skills during periods of robotic inactivity.
MethodsTen surgical residents were trained to a standardized level of robotic surgery proficiency with inanimate models. At the end of two, four and six weeks, the residents practiced with the models for a total of one hour...
ObjectiveTo compare the initial surgical outcomes of robotic and laparoscopic myomectomy in patients with symptomatic uterine myomas.
Study DesignRetrospective chart review of 86 patients undergoing robotic (RM) (n = 43) or laparoscopic (LM) (n = 43) myomectomy. Data included fibroid characteristics (number, weight, location) layers of uterine reconstruction, operating time, blood loss, complications,...
BackgroundDorsal cervical spinal fusion is a challenging procedure in fracture fixation. There is limited information in the literature about computer navigation using lateral mass screws in cases of spinal trauma.
