The integrated operating room effectively integrates the “information islands†inside and outside the operating room by realizing the openness and circulation of information. The medical staff can obtain a large amount of patient-related information in a convenient and real-time manner, and implement it with the help of a precise navigation system. Precise surgery to improve the efficiency and success rate of surgery. A research report shows that even in the United States, the efficiency of traditional operating rooms has been at a relatively low level, with an average of only 68% of the potential. The integrated operating room can greatly improve the operating efficiency of the operating room, shorten the operation time and reduce the number of personnel, and can bring a profit of 4-6 million dollars per year for a medium-sized hospital.
Integrated operating room key technology
In recent years, the construction of integrated operating rooms has been widely spread in domestic hospitals. However, from the current situation that domestic hospitals have been put into use, many of them have only completed some functions of the integrated operating room. There are widespread problems such as the incompatibility of systems with other brands of medical devices, the lack of standard protocols for data storage, the low quality of patient image data for telemedicine communication, lack of image support, and core technology support for surgical navigation.
A complete integrated operating room total solution should include the following main functions: digital recording, digital integration, digital communication, digital control and digital chemical effects.
Figure 1: Main functions of the integrated operating room
The integrated operating room controls all endoscopic equipment, conventional equipment, operating room panoramic cameras, image management equipment, air conditioning and lighting in the operating room through touch screen and voice control. The system integrates the surgical equipment organically, allowing doctors to easily control the surgical equipment directly in the sterile field with a voice or touch screen. The roving nurse can also access up to dozens of devices through a single touch screen outside the sterile field. Manage. The integrated operating room platform is compatible with image navigation surgery techniques, robotic assisted surgery techniques and remote control surgical techniques. In addition, the multimedia communication system can transmit high-quality images, diagnostic images, and live cases of the operating room in real time for teaching observation, telemedicine, on-site monitoring in the operating room, and the patient's family to watch the surgical procedure.
To achieve the above functions, there are a series of key technologies that need to be overcome. Below is a list of the eight key technologies in front of this, for enterprise reference in the development of integrated operating rooms. These eight key technologies refer to: data storage and management technology, network communication and data transmission technology, data conversion and interface technology, image processing and analysis technology, human-computer interaction technology, artificial intelligence technology, surgical planning and optimization technology, and Surgical assistive technology.
Humanization and intelligence are the development direction
Some experts believe that the image navigation system, surgical simulation system and robot system represent the development direction of the integrated operating room based on the integration of indoor and outdoor information.
Image navigation system: ImagingGuaged Surgery (ISS) is a feature of the integrated digital operating room and the core of the modern operating room. At present, imaging technology is rapidly developing, and three-dimensional digital subtraction angiography, computed tomography, intravascular ultrasound, transesophage three-dimensional echocardiography, magnetic resonance imaging and other techniques have successfully entered the operating room. Its real-time, high-definition, intelligent image processing methods and image integration technology enable intraoperative imaging, changing the state of imaging that was previously only available before or after surgery. At the same time, IGS has promoted the organic combination of imaging, radiosurgery and stereotactic technology, and has derived a variety of new treatments, such as cerebral angiography orientation, magnetic resonance directional technology, endoscopic stereotactic surgery.
IGS can reconstruct the patient's CT or MRI images in three dimensions, and accurately position the surgical instruments in the field through the intraoperative positioning system. The surgeon observes the three-dimensional images displayed on the computer monitor and observes the surgical instruments. Actual location. The IGS can also be connected to a surgical microscope or endoscope with navigation function to extend the surgical field of view beyond the microscope and endoscopic field of view, allowing the surgeon to perform surgical operations in the field while taking into account important tissues surrounding the field. structure.

Surgical Simulation System: The surgical simulation system has evolved from a universal three-dimensional human anatomical model to a personalized model. That is, after inputting the physiological data of the patient, the general model can be changed into a model of a specific patient. The simulation of the whole process of different surgical procedures was carried out, and the best surgical plan was selected before being implemented in the operation. It is truly safe to use as little damage as possible to normal tissue for optimal surgical results.
Robotic System: In December 1998, the first Da Vinci surgical robotic system was introduced, which is currently the best surgical robotic system. Nowadays, the Da Vinci surgical robot system has been developed to the 4th generation and was approved for use by the US Food and Drug Administration on April 1 this year. The University of Miami Hospital became the world's first teaching hospital to use the new DaVinci surgery system.
Currently, robotic surgery has become a major trend in minimally invasive surgery. At present, more than 600,000 robotic operations have been successfully carried out in more than 800 hospitals in 33 countries around the world. The types of surgery include urology, obstetrics and gynecology, cardiac surgery, thoracic surgery, hepatobiliary surgery, gastrointestinal surgery, otolaryngology, etc. Subject. The best surgical plan was developed from preoperative scanning, preoperative treatment, surgical simulation, and surgical planning, and the robot was surgically intervened according to the procedure. The whole process of surgery reflects the intelligent development trend of the integrated operating room driven by computer technology, information technology and automatic control technology.
