What is intraoperative C-arm machine?


With the development of science and technology, patients’ requirements for doctors are increasing day by day, and the demand for surgical risk and rapid rehabilitation is also increasing day by day, which not only requires doctors to have rich theoretical knowledge and excellent technical level, but also needs the support of powerful medical equipment. Intraoperative C-arm machine, also known as three-dimensional C-arm, can collect intraoperative three-dimensional images and quickly generate intraoperative sectional, sagittal and coronal tomography and three-dimensional images, providing surgeons with a more complete observation Angle and accurately determining the conditions of bone tissue and implants.

Take Perlove Medical’s PLX7500 series flat three-dimensional C-arm for example. It can automatically and continuously rotate 190°, collect 100 frames or 380 frames of images by means of pulse perspective, and reconstruct three-dimensional images by volume, as well as corresponding sagittal plane, coronal plane and cross section. Real-time 3D images are presented in 1 minute. Doctors can choose the window they are interested in, browse the image information in different sections layer by layer, and observe the conditions of bone tissue and implants. Surface occlusion and point occlusion are not required to guide the implant to the ideal site, achieving minimally invasive surgical treatment.

One of the advantages of intraoperative C-arm is that it can optimize the surgical process. By replacing the traditional postoperative CT examination with intraoperative CT tomography, “intraoperative CT” can be replaced with “postoperative CT” in a real sense, effectively reducing the probability of revision surgery, improving surgical efficiency and optimizing resource allocation.

The following figure is a comparison of surgical procedures using intraoperative C-arm machine and traditional two-dimensional C-arm machine:

Use intraoperative C-arm machine: X-ray examination during operation, operation is performed, intraoperative three-dimensional examination is carried out, and if any adjustment is found, timely correction is made, and then out of the operating room.

The use of two-dimensional C-arm: The same X-ray examination was performed during the operation before, and the CT examination was performed after the operation. If the effect of the operation was not satisfactory, such as the location of the screw implantation was out of alignment, revision surgery was needed to adjust it.

Through the flow comparison diagram, we can intuitively see that the intraoperative C-arm machine can effectively assist the intraoperative positioning of implants and the examination of implantation results. For example, is the location of the screw implantation out of alignment? Is it in the bone tissue? This intraoperative examination can greatly improve the success rate of surgery, reduce the risk of surgery, and avoid unnecessary postoperative revision surgery.

Compared with intraoperative mobile CT, intraoperative C-arm machine can enter the scanning area from the side through the C-arm opening, so it can be compatible with the type of operating bed in each operating room of the hospital. In addition, the C-arm machine can be easily propelled by electric power during the operation, so as to serve multiple operating rooms. On the contrary, mobile CT uses a completely closed frame during the operation, so the layout of the operating bed and the operating room have high requirements, and it is not easy to move in the operating room.

As an intraoperative imaging device, C-arm machine provides a powerful help for the further rapid development of orthopedic technology. For orthopedics, scoliosis correction, emergency trauma, minimally invasive percutaneous surgery can be quickly carried out. At the same time, C-arm machine can be combined with orthopedic surgery robot to carry out robot-assisted spinal surgery. High-definition three-dimensional image is one of the preconditions to ensure the accurate operation of robotic spinal surgery.

For the hospital, intraoperative C-arm machine can help the hospital to carry out high-end surgical methods, improve the level of clinical scientific research in the department, and help the doctors in the department to collect high-definition surgical data. Intraoperative C-arm machine can also help hospitals carry out minimally invasive surgery, improve surgical efficacy and accelerate the turnover of hospital beds
