  • Background: Minimally invasive cardiac surgery appears to offer certain advantages such as earlier postoperative recovery and a greater cosmetic effect than that achieved through conventional sternotomy. However, this approach has not yet been widely adopted in Korea to replace complex open heart surgery such as mitral valve reconstruction. This study compared the results of robot assisted minimally invasive mitral valve repair with those results of conventional sternotomy. Material and Method: From December 1993 to December 2005, 520 consecutive patients underwent mitral valve reconstruction for mitral regurgitation in our institution. These patients were subdivided according to those whose surgery used the conventional sternotomy approach (Group S, n=432) and those who underwent minimally invasive right anterior thoracotomy (Group M, n=88); we then compared the clinical results of both groups. When we performed minimally invasive right thoracotomy, we used a robot (AESOP 3000) and made an incision less than 5 cm. Result: Our study patients in both groups were similar for their age, gender and preoperative ejection fraction. There were two hospital mortalities in group S. but there was no mortality in the group M patients. Significant reductions in the ICU stay and the postoperative hospital stay were observed in the group M patients compared with the group S patients. However, both the bypass time and the aortic cross-clamp time were significantly longer in the group M patients. In spite of the confined incision in the group M patients, there were no limitations on the mitral valve repair techniques. There was a similar frequency of postoperative significant residual mitral regurgitation in both groups. Conclusion: In this study, the minimally invasive mitral valve repair showed comparable early results with the conventional sternotomy patients. We will now need long-term follow-up of these patients who underwent minimally invasive mitral valve repair, but we anticipate that based on the results of this study, we will begin to routinely perform minimally invasive cardiac surgery as out primary approach for mitral valve reconstruction.

  • The da Vinci telemanipulator system (Intuitive Surgical, Sunnyvale, CA USA) is the most advanced robotic surgical system and has been increasingly used for cardiac surgical procedures. We report out first clinical experience of use of the da Vinci telemanipulator system for endoscopic harvesting of the bilateral thoracic artery andmulti-vessel small thoracotomy off pump CABG for 3-vessel disease. The da Vinci telemanipulator system has been previously utilized primarily for mitral valve surgery.

  • The aim of this review was to evaluate minimally invasive lateral lumbar interbody fusion on the latest update. Lumbar interbody fusion was introduced recently. This study performed, a literature review of the indications, clinical outcomes, fusion rate, and complications regarding recently highlighted minimally invasive lateral lumbar interbody fusion. The indications of lateral lumbar interbody fusion are similar to the conventional anterior and posterior interbody fusion in degenerative lumbar diseases. In particular, lateral lumbar interbody fusion is an effective minimally invasive surgery in spinal stenosis, degenerative spondylolisthesis, degenerative adult deformity, degenerative disc disease and adjacent segment disease. In addition, the clinical outcomes and fusion rates of lateral lumbar interbody fusion are similar compared to conventional lumbar fusion. On the other hand, non-specific complications including hip flexor weakness, nerve injury, vascular injury, visceral injury, cage subsidence and pseudohernia have been reported. Lateral lumbar interbody fusion is a very useful minimally invasive surgery because it has advantages over conventional anterior and posterior interbody fusion without many of the disadvantages. Nevertheless, nonspecific complications during lateral lumbar interbody fusion procedure remain a challenge to be improved.

  • Background: In general, cardiac surgery has been performed via median sternotomy. During the past decade, improvements in endoscopic equipment and operative techniques have resulted in development of minimally invasive cardiac operation using small incisions. With the advent of a voice controlled camera-holding robotic arm (AESOP 3000, Automated Endoscope System for Optimal Positioning), cardiac surgery entered the robotic age. Material and Method: Between April 2004 and December 2004, a total of seventy eight patients underwent robotic cardiac surgery, of whom sixty four patients underwent robot-assisted minimally invasive cardiac surgery via 5cm right lateral minithoracotomy using voice controlled robotic arm, femoral vessels cannulation, percutaneous internal jugular cannulation, transthoracic aortic cross clamp. Other fourteen patients underwent MIDCAB via internal mammary artery harvesting using AESOP. Result: Robotic cardiac surgery were mitral valve repair in 37 cases, mitral valve replacement in 10 cases, aortic valve replacement in 1 case, MIDCAB in 14 cases, ASD operation in 9 cases, and isolated Maze procedure in 1 case. In mitral operation, mean CPB time was $165.3\pm43.1$ minutes and mean ACC time was $110.4\pm48.2$ minutes. Median length of hospital stay was 6 days (range 3 to 30) in mitral operation, 4 days (range 2 to 7) in MIDCAB, and 4 days (range 2 to 6) in ASD operation. For complications, 3 patients were required by reoperation for bleeding. There was no hospital mortality. Conclusion: Our experience of robot cardiac surgery suggests that many cardiovascular surgeons will be able to perform minimally invasive cardiac operations through small incisions with robot-assisted video-direction. Well-designed studies and close long-term follow-up will be required to analyze the benefits of robot-assisted operation.

  • Three dogs were presented with diaphyseal fracture of the tibia following separate motor vehicle accidents. On physical and orthopedic examinations, the dogs were noted to have soft-tissue swelling and a closed fracture in these tibia sites. Radiographs revealed a simple, short oblique fracture (case 1), a comminuted, spiral fracture (case 2), and a simple, spiral fracture (case 3) in tibia. Minimally invasive percutaneous plate osteosynthesis (MIPO) using a veterinary cuttable plate or locking plate was applied for the treatment of these fractures. The surgery was successful, and the fractures healed without any complications by 7 weeks (case 1), 10 weeks (case 2) and 8 weeks (case 3) after surgery. Our patients showed fast bone healing times and early weight-bearing during the treatment of their tibia fractures. Therefore, MIPO was a useful procedure for diaphyseal fracture of the tibia in veterinary orthopedics.

  • The senses that a doctor can feel is limited in MIS(Minimal Invasive Surgery) which guarantees the fast recovery of the patient and minimal incision for going in and out of instruments through the tissue of the patient. In particular, the surgical robotic teleoperation system developed recently serves with only the information of eyesight and auditory sense. Therefore force-reflection is the most demanded element of the senses in manipulating surgical instruments. In this paper, we designed the Master system and the 2 D.O.F grasper for the robotic teleoperation system(Slave) that has two force sensors on the grasper. Particularly, we focused on serve to master's handle with the contact force between tissue and the grasper of Slave.

  • Recently, robots have been used in surgical area. Robotic surgery in Minimally Invasive Surgery gives many advantages to surgeons and patients both. This study introduce a robotic assistant to improve the safety of telerobotic Minimally Invasive Surgical procedures. The master-slave system is applied to the telerobotic surgical system with the master arm, which control the system, and slave robot which operates the surgery on the patient body. By using a 3-DOF master arm, the surgeon can control the 6-DOF surgical robot under the constraint of fulcrum point. This paper explains the telerobotic surgical system and confirms the system with the precision of the robot control related to the fulcrum point to enhance the safety.
