Mobile C-arm CT is commonly known in the industry as “intraoperative CT“.Perlove’s mobile C-arm CT system provides high-definition 2D and 3D images in the operating room. Through scanning, it quickly generates three-dimensional imaging of bones during surgery, and provides cross-section, sagittal, and coronal CT-like views to help physicians more accurately diagnose lesions and plan surgical treatment programs.
In the National Medicines Management Agency’s (NMPA) Classification of Medical Devices catalog, “mobile C-arm X-ray machines” are classified as C-arms with the function of “digital tomography” or “digital subtraction angiography“, and the C-arms with the function of “digital tomography” or “digital subtraction angiography” are classified as “C-arms” with the function of “digital tomography” or “digital subtraction angiography“. C-arms with the function of “digital tomography” or “digital subtraction angiography” are managed according to the registration certificate of Class III. Other C-arms used for surgical fluoroscopy and photography, and obtaining images for clinical diagnosis are managed under Class II II registration.
Digital tomosynthesis (DTS) is based on the geometric principles of traditional tomosynthesis (CT), combined with flat-panel detector technology and digital image reconstruction algorithms to develop a new body imaging method. The digital tomography function applied to C-arm products is also commonly known in the industry as “mobile C-arm CT” technology.
At present, foreign brands of mobile C-arm CT (Siemens, Ziehmu) are Class III medical device registration certificate. Perlove Medical is the first domestic brand to get the C-arm Class III medical device registration certificate.
Application of mobile C-arm CT in joint surgery
Joints are an important anatomical basis for limb movement and play a decisive role in limb function. Therefore, in surgical treatment, not only to ensure the accuracy of fracture reset or the stability of prosthesis, but also need to restore the complete function of the joints as much as possible, so as to improve the quality of life of the patients. In the joint surgery, the mobile C-arm CT system is mainly used in the shoulder, elbow, hip, and knee joints, joint replacement and anatomical reset of the localization. The system can assist in accurate placement of prosthesis and reduce radiation time and radiation dose.
Application of mobile C-arm CT in spine surgery
In orthopedic surgery, spine surgery requires high surgical precision based on the complex anatomical structure of the spine. The mobile C-arm CT system can visualize the process and provide the operator with precise 2D and 3D images during the operation, which improves the accuracy of screw placement, shortens the surgical time, and reduces the incidence of intraoperative and postoperative complications.
Application of Mobile C-arm CT in Trauma Surgery
Mobile C-arm CT system is also widely used in trauma surgery. As most of the patients in trauma surgery are emergency and serious patients, so the preoperative preparation time is shorter, and many of them need to undergo emergency surgery, mobile C-arm CT can reconstruct three-dimensional images in real time during the operation, so that the surgeon can have a fuller understanding of some complex fractures, and be able to instantly correct the position of the screws during the operation, and place the fixation devices more accurately, reducing the number of intraoperative and postoperative complications. It also enables the surgeon to correct the position of the screws immediately during the operation and place the fixation devices more accurately, which reduces the chance of intraoperative and postoperative complications and shortens the screw placement time to a greater extent.
In previous surgeries, there may be a situation that a certain surgical effect needs to be adjusted in the postoperative CT examination of the imaging department, which often needs to be returned to the table or refurbished in order to solve the problem. The intraoperative 3D imaging function provided by the mobile C-arm CT system can merge this step into the surgical process, effectively reducing the risks for both doctors and patients and escorting the surgery.
