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.
ABSTRACT
As a physical method, electromagnetic therapy has been widely used in clinical treatment of various human diseases. In this paper, a total of 123 research papers related to the clinical application of electromagnetic therapy were retrieved from the Chinese Journal Full-text Database also known as China National Knowledge Infrastructure (CNKI), WANFANG Database, Chinese Science and Technology Journal Database (CSTJ), PubMed, Europe PMC, etc. All papers were analyzed and evaluated, and 58 effective articles were selected. The clinical application and therapeutic effects of electromagnetic therapy on several diseases were reviewed, including hypertension, diabetes, insomnia, depression and osteoporosis. The categories of commonly used electromagnetic therapy were sorted out and summarized, including magnetization at acupoints, pulsed electromagnetic fields, gyromagnetic, repetitive transcranial magnetic stimulation, and wearing magnetic items. The results show that electromagnetic therapy has a wide range of applications and small side effects, it has significant effects on some medical diseases, neurological diseases, and orthopedic diseases.
ABSTRACT
Objective To evaluate the effect of surgical management of primary venous reflux disease in lower extremity. Methods Literatures about the surgical management of venous reflux disease in lower extremity were collected and reviewed. Results In patients with primary venous reflux disease,comprehensive surgical management of concomitant superficial,deep and perforating veins might greatly improve the clinical effect.Conclusion Comprehensive surgical management will be the direction of surgical management of primary venous reflux disease in lower extremity.
