“…Current clinical examples include rigid retractors, endoscopes, and manipulators. [195][196][197][198][199] Some of these techniques, such as Levita™ Magnetic Surgical System, [195] have received the United States Food and Drug Administration (FDA) approval. Recently, concepts from soft robotics are introduced in this important medical field.…”

A magnetic field has unique advantages in controlling soft robotics inside of an enclosed space, such as surgical catheters or untethered drug‐delivering robots operating in the human body. Soft actuators, made of elastomers and gels functionalized with magnetically active materials, are natural choices to drive magnetically controlled motions of soft robots. Recent innovations in soft material technologies, including 3D printing, origami/kirigami, tough hydrogels, mechanical metamaterials, and liquid metal‐injected elastomers, offer technological foundations to develop soft actuators and robots with significantly enhanced performance. Herein, an overview of magnetic soft actuators and robots from a materials engineer's perspective is provided. First, the historical background and recent trends of magnetic soft actuators are discussed. Second, the motions of tethered or untethered magnetic soft robotics are classified into aquatic swimmers, terrestrial locomotors, and grippers. Herein, preprogrammed motion under patterned magnetic stimuli is achieved by controlled magnetization of elastomeric materials containing hard magnetic particles. Finally, the applications of magnetically controlled soft robotics in surgical and therapeutic medical devices are discussed.

“…On the basis of this principle, a magnetic device can act as a wireless internal grasper to expose the target operation fields in LESS. The magnetic anchoring guidance system (MAGS) includes cameras, retractors, dissectors, scissors, graspers, and electrosurgery devices to facilitate various minimally invasive surgeries through the ability to achieve additional instrumentation and devices despite using a single port [7,8]. Magnetic technology has been successfully used in cholecystectomy, nephrectomy, and appendectomy [4,9−12].…”

Study Objective: To evaluate and report preliminary data after the use of an internal grasper and magnetic anchoring guidance system (MAGS) to allow free movement and optimal triangulation in the abdominal cavity during gynecologic laparoendoscopic single-site surgery (LESS). Design: A prospective, single-center case series. Setting: The First Affiliated Hospital of Xi'an Jiaotong University. Patients: Eighteen female patients underwent MAGS-assisted LESS with an internal grasper. Interventions: A single surgeon performed MAGS-assisted LESS on patients with benign gynecologic diseases while documenting operative time, device insertion time, surgeon assessment of technical adaptation, patient-evaluated pain and cosmetic outcomes, adverse events, and blood loss. Measurements and Main Results: Eighteen patients underwent transumbilical MAGS-assisted LESS using an internal grasper from November 1, 2019, to December 31, 2019. The mean operative time and insertion time were 98.7 minutes and 1 minute, respectively. The use of MAGS was easily mastered by the surgeon and considered consistently useful in overcoming the limitations of LESS. The patients reported average pain scores of 4.8, 2.3, and 0.5 immediately, 24 hours, and 1 week after surgery, respectively. All patients expressed satisfaction with the postoperative cosmetic results. No serious complications were observed. The mean blood loss was 43.6 mL. Conclusion: MAGS-assisted LESS is easy to deploy and use for benign gynecologic disease and seems to result in positive outcomes. Larger randomized controlled trials are warranted.
