Only open a keyhole-sized mouth in the chest, bleeding only 100 ml, can successfully complete a coronary artery bypass surgery within two hours, and still complete under the premise of the heart beating, you will not think this is A miracle?
On June 22nd, at the 4th Beijing International Robotic Surgery Demonstration and Symposium, the surgical team led by Prof. Gao Changqing, the deputy dean of the PLA General Hospital, demonstrated the coronary artery bypass surgery without a cardiopulmonary bypass. Win the unanimous praise of the experts present.
"By the heartbeat surgery means to perform surgery on a two-millimeter blood vessel, to cut the coronary artery, and finally to perform vascular anastomosis. The difficulty is conceivable. This is the minimally invasive limit of robotic heart surgery. Several cardiac surgeons are able to perform this procedure.†The foreign experts commented that “the robot allows the doctor to break through the limitations of the human eye. Through robotic surgery, the patient’s trauma is minimized and the surgery is more precise.â€
Robotic surgery makes patients less traumatic
In the 20th century, the formation and development of minimally invasive surgery in the medical field, laparoscopic technology is a typical representative, but the instruments used by the surgeon at this stage are still traditional common thoracoscopy equipment, it is difficult for surgeons to master precise operation, and operation It is very uncomfortable, and true intracardiac operation still requires the auxiliary incision of the chest wall to complete.
Until the end of the 1990s, research and development of medical surgical robot systems came into being to overcome the defects of endoscopic techniques and to pursue more perfect minimally invasive surgery.
The earliest concept of robotic surgery was the first automatic endoscope positioning system developed by Computer Motion in 1994 to assist minimally invasive surgery. However, it was not able to perform instructions alone for surgery, but only a mirror. "Electronic manipulator."
The robotic surgical instrument used in the operating room of the hospital is the da Vinci system of Intuitive Surgical of the United States. The advent of robotic systems has made it possible for some of the original surgeons to be technically difficult or even impossible to solve.
“Through the video manipulation system, the operator and the robot arm are connected by circuit. The doctor console is equipped with a three-dimensional vision system and an action calibration system. The movement of the doctor's arm, wrist and fingers is accurately recorded in the computer by sensors and simultaneously translated. Give the robot arm. The operator moves away from the operating table, and directs and controls the bedside robot to realize the complete imitation of the operation in the patient's body." Intuitive Surgical staff introduced.
"The advantages of robotic manipulation of surgical instruments are many. For example, accurate positioning of medical images can eliminate manual vibration to perform continuous movements, and it can work in an environment that is unfavorable to doctors," said Dr. Yang Ming, Department of Cardiovascular Surgery, PLA General Hospital.
Compared with traditional heart surgery, the incision is usually less than 1 cm in the sternum, and the robotic incision is generally less than 1 cm. The trauma is very small and the bleeding is less. In general, traditional thoracotomy surgery takes about 3 months to recover, and robotic cardiovascular surgery, the patient's postoperative recovery time is only about 1 week. Even in the case of heart bypass, major surgery such as heart valve repair, patients can get out of bed the next day after surgery.
