BackgroundA surgeon performs various surgical actions with the help of teleoperation technology during robot assisted minimally invasive surgery. The slave manipulators reproduce every movement of the surgeon's hands, completely and faithfully. However, in some cases, unexpected collisions between surgical instruments and fragile organs might occur around the lesion, causing further injury.

BackgroundThere are several complications associated with Stent‐assisted Coil Embolization (SACE) in cerebral aneurysm treatments, due to damaging operations by surgeons and undesirable mechanical properties of stents. Therefore, it is necessary to develop an in vitro simulator that provides both training and research for evaluating the mechanical properties of stents.
MethodsA new in vitro simulator...
BackgroundHigh‐frequency electricity is used in the majority of surgical interventions. However, modern computer‐based training and simulation systems rely on physically unrealistic models that fail to capture the interplay of the electrical, mechanical and thermal properties of biological tissue.
MethodsWe present a real‐time and physically realistic simulation of electrosurgery by modelling the...
BackgroundThe existing methods in dental clinical operations for hard tissue removal have several drawbacks which affect the long‐term success of the dental treatment.
MethodsIn this paper, we introduce a miniature robotic device called LaserBot, which can manipulate a femtosecond laser beam to drill/burr a decayed tooth to realize clinical tooth crown preparation. In order to control the 3D motion...
BackgroundThe objective of this study was to describe our early experience with robot‐assisted partial nephrectomy (RAPN) incorporating selective arterial clamping, using an image overlay navigation system.
MethodsThree‐dimensional images were reconstructed from computed tomography using open source processing software, OsiriX, and were directly visualized on the screen of a da Vinci surgeon's console...
BackgroundThere is scanty experience concerning robot‐assisted Ivor–Lewis oesophagectomy, so every new experience is helpful.
MethodsWe describe the techniques and short‐term results of Ivor–Lewis oesophagectomy using a laparoscopic approach and robot‐assisted thoracoscopy, and an observational study of prospective surveillance of the first 14 patients treated for oesophageal cancer. A gastric tube...
BackgroundA transanal approach for total mesorectal excision (TME) using a single incision port is feasible. The disadvantages are technical difficulties associated with limited manoeuvrability.
MethodsWe present our first experience with robotic‐assisted transanal total mesorectal excision. A 48 year‐old woman with a tumour 8 cm from the anal verge was successfully operated using a transanal approach...
BackgroundThe objective of this study was to evaluate the safety and feasibility of robot‐assisted thoracoscopic surgery (RATS).
MethodsFrom May 2009 to May 2013, 48 patients with intrathoracic lesions underwent RATS with the da Vinci® Surgical System was reported (11 lobectomies, 37 mediastinal tumour resections).
ResultsRATS was successfully and safely completed in all 48 patients. Conversion of...
BackgroundAccurate localization of bone surfaces remains a challenge hampering adoption of ultrasound guidance in computer‐assisted orthopaedic surgery. Local phase image features have recently been proven efficacious for segmenting bone surfaces from ultrasound images, but the quality of the processing depends on numerous filter parameters that are currently set through a trial and error process...
BackgroundRobotic‐assisted minimally invasive surgery (MIS) can benefit both patients and surgeons. However, the learning curve for robotically assisted procedures can be long and the total system costs are high. Therefore, there is considerable interest in new methods and lower cost controllers for a surgical robotic system.
MethodsIn this study, a knife‐master and a forceps‐master, shaped similarly...
BackgroundPharyngeal stenosis is a complication of head and neck cancer and sleep apnea treatment that results in functional impairment. Due to the location of the stenosis and tendency to recur, surgical management is challenging. Robotic surgery may allow these areas to be treated with surgical technique that would be difficult using traditional approaches.
MethodsA retrospective chart review was...
BackgroundFemoral tunnel positioning is a difficult, but important factor in successful anterior cruciate ligament (ACL) reconstruction. Computer navigation can improve the anatomical planning procedure besides the tunnel placement procedure.
MethodsThe accuracy of the computer‐assisted femoral tunnel positioning method for anatomical double bundle ACL‐reconstruction with a three‐dimensional template...
BackgroundCosmesis is of increasing importance to the otolaryngology patient population. This is the first report of clinical outcomes of robot‐assisted neck dissection by North American groups.
MethodsThis is a retrospective case‐control study. Cases included three patients who underwent isolated, ipsilateral robot‐assisted neck dissection. Operative time, estimated blood loss, lymph node retrieval,...
BackgroundSurgical robotic systems have been proven to be accurate and dexterous during minimally invasive surgery (MIS). However, single incision laparoscopic surgery (SILS) requires more compact robotic arms with sufficient dexterity and output.
MethodsA shape memory alloy (SMA)‐actuated instrument was adopted to assist operations. The instrument fixed at the slave site had three degrees of freedom...
BackgroundOur main aim was to evaluate the value of medical image three‐dimensional visualization system (MI‐3DVS) in pancreaticoduodenctomy patients with hepatic artery variance.
Methods114 patients who had undergone pancreatoduodenectomy were retrospectively summarized and analyzed. Clinical data of 64‐slice multidetector CT angiography (64‐MDCTA) scanning was introduced into MI‐3DVS for procedural...
