Full process visualization of surgery: An intelligent visualization system robot from a hospital in the city completes minimally invasive surgery for complex pelvic fractures. HoloSight | Team | Robot
Recently, Lin Haodong, Director of the Trauma Clinical Medical Center at Shanghai First People's Hospital, and Wang Jiandong, Chief Physician, completed a closed reduction minimally invasive internal fixation surgery for a complex pelvic fracture and a femoral neck fracture with the assistance of a new "HoloSight intelligent visualization system" robot. This is also the first appearance of HoloSight robots in Shanghai. It is reported that the system combines mixed reality and high-precision optical positioning and tracking technology, which can fully monitor the process of pelvic fracture reduction, instantly build a visual three-dimensional model, and help surgeons accurately complete various minimally invasive orthopedic surgeries. At the same time, it can also shorten surgical time, reduce intraoperative bleeding and radiation damage, make trauma treatment more minimally invasive, precise, and intelligent, and achieve the modern medical concept of accelerated rehabilitation surgery.
Mr. Xu, who is 68 years old this year, was sent to Shanghai First People's Hospital for emergency treatment due to an accidental fall from a height. After examination, Mr. Xu suffered a serious pelvic fracture. Since there are many important blood vessels, nerves and visceral organs around the pelvis, and Mr. Xu's pelvic fracture type is the most serious type C vertical fracture, he also suffers from type II diabetes, hypertension, coronary heart disease and other basic diseases, so it is difficult to operate. After multidisciplinary consultations to stabilize vital signs and sufficient communication with the patient's family, the trauma clinical medical center team decided to implement minimally invasive "pelvic fracture closed reduction and hollow nail internal fixation surgery" for Mr. Xu with the assistance of a new "HoloSight intelligent visualization system" robot.
Traditional minimally invasive surgery for pelvic fractures requires the surgeon to perform the surgery within a limited field of vision, relying on memory and spatial conception of deep anatomical tissues, and in conjunction with intraoperative X-ray fluoroscopy. Due to the complex anatomy of the hip and pelvis, surgery is prone to nerve and vascular damage, and both patients and doctors are exposed to significant radiation from the fluoroscopy machine.
The "HoloSight Intelligent Visualization System" robot, with the support of optical positioning technology, can achieve intelligent and accurate matching between bone models and spatial tracking data through intelligent feature recognition and automated registration algorithms, and complete real-time 3D modeling. Doctors can visually observe the bone condition on the screen and complete the entire process of fracture reduction, intelligent planning, and assisted nail placement based on this.
On the day of the surgery, the trauma center team placed a locator at the patient's pelvic iliac crest and installed R-shaped and L-shaped trackers. HoloSight robots perform high-precision tracking of patient bones in a closed environment, displaying real-time spatial position and posture. The fracture morphology of the patient is presented on the screen in the form of a 3D animated model, and the surgical team can observe in real-time from multiple views and any angle. The surgery only required a few small incisions of 1 centimeter to complete minimally invasive internal fixation, effectively fixing the fracture while avoiding risks such as major bleeding and vascular and nerve damage.
In addition, the trauma center team also accurately implanted the femoral neck dynamic cross nail system in a patient with a femoral neck fracture using HoloSight robot navigation. This minimally invasive surgery was completed with only a 3cm incision.
It is reported that the HoloSight trauma robot can provide accurate and visual treatment plans for various surgeries such as closed reduction of fractures, internal fixation of pelvic and acetabular fractures, and internal fixation of limb fractures. The trauma center team of a hospital in Shanghai will continue to practice the concept of accelerated rehabilitation surgery, continue to carry out minimally invasive surgery, embedded postoperative rehabilitation and other measures, and provide patients with efficient and high-quality diagnosis and treatment services.
