Da Vinci Surgery

When people talk about Da Vinci Surgery, it is not a special surgery performed by him. Reason simply because he is an artist, not surgeon.....haha...lame joke...However, why robotic surgery still name under Da Vinci? According to the manufacture of Da Vinci Surgical System, Da Vinci Surgical system is so called "Da Vinci" in part because Leonardo Da Vinci invented the first robot, used anatomical accuracy and three-dimensional details to bring his work to life.

Da Vinci Surgical sytem is a type of Robotic Surgical system designed to facilitate and complete a complex surgery using a minimally invasive approach. The system is controlled by a surgeon from a console. Previously, it was commonly used for prostatectomy. Now, it is increasingly used in cardiac valve repair, coronary artery diseases, gynaecological problems and oncology, colon cancer, kidney disorders and kidney cancer.

The da Vinci System consists of a surgeon’s console that is typically in the same room as the patient and a patient-side cart with four interactive robotic arms controlled from the console. Three of the arms are for tools that hold objects, act as a scalpel, scissors, bovie, or unipolar or dipolar electrocautary instruments. The fourth arm is for an endoscopic camera with two lenses that gives the surgeon full stereoscopic from the console. The surgeon sits at the console and looks through two eye holes at a 3-D image of the procedure, meanwhile maneuvering the arms with two foot pedals and two hand controllers. The da Vinci System scales, filters and translates the surgeon's hand movements into more precise micro-movements of the instruments, which operate through small incisions in the body.

To perform a procedure, the surgeon uses the console’s master controls to maneuver the patient-side cart’s three or four robotic arms (depending on the model), which secures the instruments and a high-resolution endoscopic camera. The instruments’ jointed-wrist design exceeds the natural range of motion of the human hand; motion scaling and tremor reduction further interpret and refine the surgeon’s hand movements. The da Vinci System incorporates multiple, redundant safety features designed to minimize opportunities for human error when compared with traditional approaches. At no time is the surgical robot in control or autonomous; it operates on a "Master:Slave" relationship, the surgeon being the "Master" and the robot being the "Slave." Da Vinci Surgical System

Erm, why i am so eager to talk about Da Vinci surgery in this lovely morning?? Partly is because i am impressed by National Heart Centre of Singapore. Since imported this high-tech surgical system in December 2006, cardiothoracic surgeons from NHC of Singapore have been performed varous operations by using Da Vinci Surgery. Cases operated were Mitral Valve repair, CABG, VSD and resection of mediastinal tumour. Really impressive!! Luckily, we still have Prince Court Medical Centre that make Malaysia proud of Da Vinci. They started Da Vinci surgery on urological patient

This make me wonder, while Singapore National Heart Centre is so excellent in clinical and research, where is our beloved Institute Jantung Negara(IJN)??

Click on National Heart Centre website! You notice that various excellent clinical researches and trials have been carried out in NHC such as Percutanous Aortic Valve Replacement, Retrogade technique for total chronic obstructio etc..The most recent was the combine heart and liver transplant in NHC. This is the Asian's 1st combine heart and liver transplantation which jointly performed by the cardiothoracic surgeon from NHC and transplant surgeon from Singapore Genaral Hospital. Heart transplantation was led by Dr C. Sivathasan, Dr Lim Chong Hee and Dr Lim Yeow Phang whereas the liver transplantation was led by Dr Tan Yu Meng, Dr Chew Peng Chung and Dr Alexander Chung.

Now click on our beloved Institute Jantung Negara! Yes, you will find "First in Malaysia" here and "first in malaysia" there....haha...
