Lobectomy is the standard treatment for early non-small cell lung cancer. Various surgical techniques for lobectomy have been developed, and minimally invasive thoracic surgery, such as video-assisted thoracic surgery or robot-assisted thoracic surgery, has been considered as an alternative to conventional open thoracotomy. The recently robotic lobectomy technique has developed since the first case series was published in 2002. Several studies have reported that robotic lobectomy has comparable oncologic and perioperative outcomes to those of video-assisted thoracic surgery lobectomy and open lobectomy. However, robotic lobectomy remains a challenge for surgeons because of the steep learning curve, reduced tactile sensation, difficulty in port placement, and challenges in cooperation between the surgeon and assistant. Many studies have reported on robotic lobectomy, but few have presented surgical techniques for robotic lobectomy. In this article, the surgical techniques and optimal performance of robotic lobectomy are described in detail for all 5 types of lobectomy for surgeons beginning with robotic lobectomy.

Recent medical robot systems perform surgery operations, by following the preplanned trajectory and surgical procedures. Depending on the complexity of surgery operations, they are operated in manual, semi-automatic or full automatic mode. To improve the performance of those medical robot systems, development of the simulator and more advanced auto-illumination system, in which intensity of light, direction and focal point can be controlled automatically according to the varied environments during surgical operations. are required. Therefore, in this paper, the simulator for SPINEBOT system which is a computer-intergrated robotic surgery system are developed. And further, an auto-illumination system which will be integrated to the SPINEBOT system is investigated and its preliminary design is described.

Geometry calculation Using Abdominal internal organ image from traditional laparoscopy or robotic surgery system we can make depth informations through measured 3D structure informations is very helpful to doctors, depth information is mare useful then others that use traditional laparoscopy or robotic surgery system to many doctors. however, traditional method are incomplete. less experienced doctors make much mare prohability of mistake. Hence, 3D information of organ is very helpful to the less experienced doctors. it will be greate role of reducing medical accidents and surgical time. We can get 3D informations using geometrical calculation method in robotic surgical system. also suggested method is needed in traditional surgical method without the need to create a new system, finally, We can get 3D information from traditional system without any new system, it take advantage in cost and create high efficiency. mare information will provided to many doctors.

The increased application of the da Vinci robotic platform (Intuitive Surgical Inc.) for microsurgery has led to the development of new adjunctive surgical instrumentation. In microsurgery, the robotic platform can provide high definition $12{\times}-15{\times}$ digital magnification, broader range of motion, fine instrument handling with decreased tremor, reduced surgeon fatigue, and improved surgical productivity. This paper presents novel adjunctive tools that provide enhanced optical magnification, micro-Doppler sensing of vessels down to a 1-mm size, vein mapping capabilities, hydro-dissection, micro-ablation technology (with minimal thermal spread-$CO_2$ laser technology), and confocal microscopy to provide imaging at a cellular level. Microsurgical outcomes from the use of these tools in the management of patients with infertility and chronic groin and testicular pain are reviewed. All these instruments have been adapted for the robotic console and enhance the robot-assisted microsurgery experience. As the popularity of robot-assisted microsurgery grows, so will its breadth of instrumentation.

Background: Robot-assisted repair of atrial septal defect (ASD) can be performed under either beating-heart or non-beating-heart conditions. However, the risk of cerebral air embolism (i.e., stroke) is a concern in the beating-heart approach. This study aimed to compare the outcomes of beating- and non-beating-heart approaches in robot-assisted ASD repair. Methods: From 2010 to 2019, a total of 45 patients (mean age, 43.4±14.6 years; range, 19-79 years) underwent ASD repair using the da Vinci robotic surgical system. Twenty-seven of these cases were performed on a beating heart (beating-heart group, n=27) and the other cases were performed on an arrested or fibrillating heart (non-beating-heart group, n=18). Cardiopulmonary bypass (CPB) was achieved via cannulation of the femoral vessels and the right internal jugular vein in all patients. Results: Complete ASD closure was verified using intraoperative transesophageal echocardiography in all patients. Conversion to open surgery was not performed in any cases, and there were no major complications. All patients recovered from anesthesia without any immediate postoperative neurologic symptoms. In a subgroup analysis of isolated ASD patch repair (beating-heart group: n=22 vs. non-beating-heart group: n=5), the operation time and CPB time were shorter in the beating-heart group (234±38 vs. 253±29 minutes, p=0.133 and 113±28 vs. 143±29 minutes, p=0.034, respectively). Conclusion: Robot-assisted ASD repair can be safely performed with the beating-heart approach. No additional risk in terms of cerebral embolism was found in the beating-heart group.

Robotic thymectomy has been adopted recently and has been shown to be safe and feasible in treating thymic tumors and myasthenia gravis. The surgical indications of robotic technology are expanding, with advantages including an excellent surgical view and sophisticated manipulation. Herein, we describe technical aspects, considerations, and outcomes of robotic thymectomy.

Objective : In the field of spinal surgery, a few laboratory results or clinical cases about robotic spinal surgery have been reported. In vivo trials and development of related surgical instruments for spinal surgery are required before its clinical application. We investigated the use of the da $Vinci^{(R)}$ Surgical System in spinal surgery at the craniovertebral junction in a human cadaver to demonstrate the efficacy and pitfalls of robotic surgery. Methods : Dissection of pharyngeal wall to the exposure of C1 and odontoid process was performed with full robotic procedure. Although assistance of another surgeon was necessary for drilling and removal of odontoid process due to the lack of appropriate end-effectors, successful robotic procedures for dural sutures and exposing spinal cord proved its safety and dexterity. Results : Robot-assisted odontoidectomy was successfully performed in a human cadaver using the da $Vinci^{(R)}$ Surgical System with few robotic arm collisions and minimal soft tissue damages. Da $Vinci^{(R)}$ Surgical System manifested more dexterous movement than human hands in the deep and narrow oral cavity. Furthermore, sutures with robotic procedure in the oral cavity demonstrated the advantage over conventional procedure. Conclusion : Presenting cadaveric study proved the probability of robot-assisted transoral approach. However, the development of robotic instruments specific to spinal surgery must first precede its clinical application.

MMinimally invasive surgery (MIS) for early stage lung cancer has been an important treatment modality. However, the ergonomic discomfort and counterintuitive instruments hindered the application of video-assisted thoracic surgery (VATS) to more advanced procedures. To improve the compliance with MIS, robotic surgery was adopted. This advance aimed to alleviate the shortcomings of VATS by maximizing the comfort of the surgeon while providing instruments that enabled technically demanding operations and three-dimensional views with increased freedom for intrathoracic movement owing to EndoWrist$^{(R)}$. In this session, we introduced the clinical applications and its results of robot-assisted thoracic surgery in the field of lung cancer surgery. In conclusion, robot-assisted pulmonary resection with lymph node dissection for lung cancer is safe as well as feasible, and it results in a satisfying postoperative outcome. Robot-assisted surgery may provide a good alternative to conventional open or thoracoscopic surgery for lung cancer, provided that the cost effectiveness and long-term prognosis are confirmed.
