“…After pre‐operative teaching, preparation of the equipment and set‐up was perceived to be simple and straight‐forward. The mean time from start to introduction of Magnetic Gasper Device (MGD) was 10 minutes, 7–24 and the mean MGD position and release time was 1 (1–2 min). The mean MGD first coupled time was 9 (1–65 min), and the mean MGD removed time was 39 (21–57 min).…”

Background Magnetic technologies have been introduced to reduce invasiveness of surgical procedures. This study was aimed to analyse the performance of a novel combined magnetic‐robotic controller as an enhanced accessory to the Magnetic Surgical System in laparoscopic cholecystectomy (LC). Methods This was a prospective study of 10 consecutive patients undergoing LC with this novel surgical system. Results Ten patients were included, nine were female. The mean age was 30.3 ± 9 years. All patients had chronic cholecystitis. Procedures were completed successfully. The median operative time was 50 ± 11 min. The system performed effectively in all cases with no need of additional interventions. There were no device‐related complications or side effects. All patients were discharged the same day. Recovery was uneventful during follow‐up. Conclusions This study demonstrates the first in‐human successful performance of surgeries utilizing a novel combination of magnetic and robotic technologies in one integrated system.

“…The concept of magnetic surgery (MS) has been developed to increase the benefits of MIS, as this technology reduces the invasiveness of procedures by decreasing the number of trocar access sites needed 11 . Additionally, robotic surgery (RS) enhances; flexibility, precision, and control during delicate and complex procedures.…”

“…Most obese patients are complicated with fatty liver, and exposure to the liver has always been the innovative direction pursued by weight-loss doctors [11,12] . Although there are many methods, such as abdominal cavity blocking of liver with Kirschner's needle xiphoid process, glue adhesion to liver suspension, liver puncture, and purse-needle suspension, each method has advantages and disadvantages [14,13] .…”

Objective To investigate the safety and effectiveness of ultra-minimally invasive surgical instruments in laparoscopic sleeve gastrectomy (LSG). Methods A total of 134 patients, including 67 patients who underwent 4-hole LSG, 29 patients who underwent 3-hole LSG, and 38 patients who underwent ultra-minimally invasive laparoscopic sleeve gastrectomy (ULSG), from July 2018 to December 2022 were included in this study. The operation times, bleeding volumes, and pain scores among the three groups (4-hole LSG group, 3-hole LSG group, ULSG group) were compared. Results The bleeding volumes in the 4-hole LSG group, 3-hole LSG group, and ULSG group were 6.6 ± 5.1 ml, 10.0 ± 4.9 ml, and 5.6 ± 3.3 ml, respectively. The operation times in the 4-hole LSG group, 3-hole LSG group, and ULSG group were 103.8 ± 21.3 min, 122.9 ml ± 24.0 min, and 110.7 ± 30.0 min, respectively. The pain scores in the 4-hole LSG group, 3-hole LSG group, and ULSG group were 5.0 ± 2.0, 4.0 ± 1.5, and 3.9 ± 1.6, respectively. However, one case each of gastric leakage (1.49%), gastric stenosis (3.45%), and severe vomiting (2.63%) were reported in the 4-hole LSG, 3-hole LSG group, and ULSG group, respectively (P = 0.909). Conclusion Ultra-minimally invasive instrument-assisted LSG (ULSG) is a safe and convenient operation that enhances skin beauty. Besides, the method of picking, blocking, and pulling can better expose the visual field and cut the gastric tissue.

“…A similar use of an internal–external paired magnet system is also being studied in obstructive sleep apnea treatment—as an alternative to continuous positive airway pressure (CPAP)—by advancing the hyoid bone forward to maintain airway patency during sleep ( Figure 3 ) [ 102 , 133 ]. Other surgical applications of an internal–external paired magnetic system include the use of internal detachable magnetic graspers manipulated by external magnets to aid in organ retraction during laparoscopic gallbladder surgery and bariatric surgery to decrease the number of incisions ( Table 3 ) [ 91 , 92 , 93 , 95 , 96 , 134 ]. These multiple uses highlight the potential and versatility of magnetic surgical systems that can manipulate internal tissues via an external source.…”

The Evolving Use of Magnets in Surgery: Biomedical Considerations and a Review of Their Current Applications

The novel use of magnetic force to optimize modern surgical techniques originated in the 1970s. Since then, magnets have been utilized as an adjunct or alternative to a wide array of existing surgical procedures, ranging from gastrointestinal to vascular surgery. As the use of magnets in surgery continues to grow, the body of knowledge on magnetic surgical devices from preclinical development to clinical implementation has expanded significantly; however, the current magnetic surgical devices can be organized based on their core function: serving as a guidance system, creating a new connection, recreating a physiologic function, or utilization of an internal–external paired magnet system. The purpose of this article is to discuss the biomedical considerations during magnetic device development and review the current surgical applications of magnetic devices.
