Research progress of magnetic anchor assist technology in surgery / 国际生物医学工程杂志

ABSTRACT

With the development of magnetic materials more widely used in surgical instruments, the development of magnetic surgery technology has continuously made breakthroughs and innovations. Magnetic anchor assist technology has become an important surgical method due to its precise positioning and non-contact traction. The majority of clinical magnetic anchor system consist a target magnet in vivo and a traction magnet in vitro. The non-contact traction and anchoring of the target can be achieved through the mechanical interaction of the anchor magnet and the traction magnet. This method not only can prevent the entanglement and collision between surgical instruments, but also can provide a good surgical field of vision for the surgical area, making the surgical process safer and more efficient. In this paper, 69 articles related to the application of magnetic anchor assist technology in surgical procedures were retrieved by conducting searches in the Chinese Journal Full-text Database(CNKI), Wanfang Database, VIP Chinese Sci-tech Journal Database, PubMed and other databases. After analysis and evaluation, a total of 36 papers were screened. The research progress and application status of magnetic anchor assist technology in combination with laparoscopy, thoracoscopy, and endoscopy in surgical operations were introduced. The results show that the magnetic anchor assist technology can greatly promote the development of minimally invasive surgery, but there are still problems in the application process, such as mutual interference of magnets and instability of the magnetic force, which still need to be further studied and improved.
