Abstract
Magnetic microrobotics is a promising technology for improving minimally invasive surgery (MIS) with the ambition of enhancing patient care and comfort. The potential benefits include limited incisions, less hemorrhaging and postoperative pain, and faster recovery time. To achieve this, a key issue relies on the design of a proper electromagnetic actuation (EMA) setup which is based on the use of magnetic sources. The magnetic field and its gradient generated by the EMA platform is then used to induce magnetic torque and force for microrobot manipulations inside the human body. Like any control systems, the EMA system must be adapted to the given controlled microrobot and customized for the application. With great research efforts on magnetic manipulating of microrobots, the EMA systems are approaching commercial applications, and their configurations are becoming more suitable to be employed in real medical surgeries. However, most of the proposed designs have not followed any specific rule allowing to take into account the biomedical applications constraints. Through reviewing the different proposed EMA systems in the literature, their various specifications and configurations are comprehensively discussed and analyzed. This study focus on EMA platforms that use electromagnets. From this review and based on the biomedical application specifications, the appropriate EMA system can be determined efficiently.

Fan X, Duan K, Zhang C, Guan X. Feasibility of two robotic single-site surgery techniques for adolescent endometriosis: Focal versus butterfly. Int J Med Robot 2021; 18:e2339. [PMID: 34661960 DOI: 10.1002/rcs.2339] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 09/24/2021] [Accepted: 10/08/2021] [Indexed: 11/07/2022]
Abstract
OBJECTIVE This study examined the feasibility of robotic laparoendoscopic single-site surgery (LESS) for the treatment of adolescent endometriosis (n = 36). Additionally, we assessed a novel technique known as butterfly resection for severe cases. METHODS This was a retrospective study of women from 12 to 21 years old who received therapeutic robotic LESS for symptomatic endometriosis by a single experienced surgeon. RESULTS There were 32 cases of peritoneal and four cases of deep infiltrating endometriosis (DIE). Focal resection was performed in 9/32 peritoneal and all DIE cases; butterfly resection was performed in the remaining 23/32 peritoneal. At 3 months, 16/23 had complete resolution of pelvic pain in the butterfly group versus 10/13 in the focal group (P = 0.64). CONCLUSION Robotic LESS produces safe outcomes with low complication rates. Butterfly resection may be considered for extensive lesions, with similar levels of pain relief compared to traditional focal resection techniques. CAPSULE Single-site robotic surgery produces safe outcomes with low complication rates in adolescents with endometriosis, with techniques customized based on disease severity.

Application of robotic single-site surgery with optional additional port for endometriosis: a single institution's experience. J Robot Surg 2021; 16:127-135. [PMID: 33651315 DOI: 10.1007/s11701-021-01217-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Accepted: 02/20/2021] [Indexed: 10/22/2022]
Abstract
To evaluate the safety and feasibility of treating stage I-IV endometriosis patients with robotic single-site surgery (RSSS). A retrospective chart review was conducted on 334 patients with endometriosis treated by a single surgeon at a university hospital from January 2015 to November 2019. Surgeries were performed in a single institution between 2015 and 2019. All patients presented with pelvic pain and underwent surgical resection of the lesion. American Society of Reproductive Medicine (ASRM) standards were used to classify endometriosis. The primary goal of this study is to investigate the feasibility and safety of RSSS for surgical resection of stage I-IV endometriosis patients. We will compare patient characteristics and surgical parameters, such as blood loss, operating time, and postoperative complications, across different endometriosis stages to evaluate the effectiveness of this novel technique. RSSS was used for all cases, with no conversions to laparotomy or traditional laparoscopy. One to two additional ports were placed in 41 patients with deeply infiltrating endometriosis (DIE) involving the colorectal and urinary tract and/or extensive pelvic adhesions. Across patient groups, there were no significant differences in age, BMI, fertility history, abdominal surgery history, and hysterectomy ratio (P > 0.05). The median operation time was 140.25 min (range: 85.50-260.00 min, P < 0.05) and median blood loss was 31.25 mL (range: 15-100 mL, P < 0.05). Histopathology supported the diagnosis in 259/334 patients. The undiagnosed patients were associated with lower ASRM scores. For 83.3% of patients (295/334), the length of hospital stay was < 24 h. The postoperative complication rate was 6.0% (20/334), although only two cases were severe. Our results indicate that RSSS is an alternative, safe, and acceptable platform for the surgical treatment of all stages of endometriosis.

Abstract
PURPOSE The development of surgery is to be minimally invasive and collaborative with robot systems, which has caught increasing attention in recent years. However, the narrow access routes and confined working spaces in vivo usually make distal end-effectors of surgical systems not easy to operate. To overcome this problem, a novel cable-driven distal end-effector mechanism designed for single-port robotic surgery was proposed. METHODS A cable-driven joint structure and the corresponding methods of threading cables were proposed which can maintain the length and even the tension force of cables constant during operation. Based on the proposed joint structure, the cable-driven distal end-effector mechanism consists of a parallelogram mechanism and a snake mechanism. The parallelogram mechanism is used to enlarge its reachable workspace through establishing the triangulation of operation. The snake mechanism is used to achieve the expected pose through providing sufficient bending degrees of freedom. All of the degrees of freedom can be decoupled at the expense of a slightly more tedious process of threading cables. RESULTS The primary prototype and its miniature assembled and threaded manually performed as expected regardless of bend, translation and their combination. But the inadequate tension force of cables and assembly errors affect the load capacity and accuracy, which need to be improved by automatic assembly. CONCLUSION A cable-driven distal end-effector mechanism composed of a parallelogram mechanism, and a snake mechanism used for single-port robotic surgery was proposed. The mechanism adopts a novel cable-driven joint structure and corresponding methods of threading cables to keep the length and even the tension force of cables constant during surgery.

Abstract
While laparoendoscopic single-site surgery (LESS) appears to be feasible and safe, instrument triangulation, tissue handling, and other bimanual tasks are difficult even for experienced surgeons. Novel technologies emerged to overcome LESS' procedural and ergonomic difficulties of "tunnel vision" and "instrument clashing." Surgeon kinematics, self-reported workload and upper body discomfort were used to compare straight, bent and two articulating instruments while performing two basic surgical tasks in a LESS simulator. All instruments resulted in bilateral elevation and rotation of the shoulders, excessive forearm motion and flexion and ulnar deviation of wrists. Surgeons' adopted non-neutral upper extremity postures and performed excessive joint excursions to compensate for reduced freedom of movement at the single insertion site and to operate the instrument mechanisms. LESS' cosmetic benefits continue to impact laparoscopic surgery and by enabling performance through improved instruments, ergonomic improvement for LESS can reduce negative impact on surgeon well-being and patient safety.

Abstract
Nowadays robots play an important role in society, mainly due to the significant benefits they provide when utilized for assisting human beings in the execution of dangerous or repetitive tasks. Medicine is one of the fields in which robots are gaining greater use and development, especially those employed in minimally invasive surgery (MIS). However, due to the particular conditions of the human body where robots have to act, the design of these systems is complex, not only from a technical point of view, but also because the clinical needs and the normativity aspects are important considerations that have to be taken into account in order to achieve better performances and more secure systems for patients and surgeons. Thus, this paper explores the clinical needs and the technical requirements that will trace the roadmap for the next scientific and technological advances in the field of robotic surgery, the metrics that should be defined for safe technology development and the standards that are being elaborated for boosting the industry and facilitating systems integration.

Abstract
Robotic-assisted laparoscopic surgery in urology is an ever progressing field, and boundaries are constantly broken with the aid of new technology. Advancements in instrumentation have given birth to the era of robotic laparoendoscopic single-site technique (R-LESS). R-LESS however, has not gained widespread acceptance due to technical hurdles such as adequate triangulation, robotic arm clashing, decreased access for the bedside assistant, lack of wrist articulation, continued need for an axillary/accessory port, lack of robust retraction, and ergonomic discomfort. Many innovations have been explored to counter such limitations. We aim to give a brief overview of a history and development of R-LESS urologic surgery and outline the latest advancements in the realm of urologic R-LESS. By searching PubMed selectively for relevant articles, we concluded a literature review. We searched using the keywords: robotic laparoscopic single incision, robotic laparoendoscopic single-site, single incision robotic surgery, and R-LESS. We selected all relevant articles in that pertained to single-site robotic surgery in urology. We selected all relevant articles that pertained to single-site robotic surgery in urology in a table encompassed within this article. The development of the R-LESS procedures, instrumentations, and platforms has been an evolution in progress. Our results showed the history and evolution toward a purpose-built single-port robotic platform that addresses previous limitations to R-LESS. Even though previous studies have shown feasibility with R-LESS, the future of R-LESS depends on the availability of purpose-built robotic platforms. The larger concern is the demonstration of the definitive advantage of single-site over the conventional multiport surgery.

Abstract
OBJECTIVES We compared perioperative results and complications of reconstructive surgery of the urinary tract performed using a multichannel platform through the umbilicus and one additional 3.5-mm with a cohort of patients simultaneously treated with conventional 4-port laparoscopy. MATERIALS AND METHODS Matched-pair study comparing perioperative outcomes, postoperative visual analogue pain scale (VAPS) and morbidity of 2-port (n = 20) and 4-port (n = 10) laparoscopic reconstructive urological surgery. Preoperative and perioperative data compared included demographics, type of surgery, operative time, blood loss, decrease in serum hemoglobin, operative complications, length of stay and postoperative complications according to Clavien-Dindo classification. RESULTS There was no significant difference between groups regarding age, gender, body mass index, American Society of Anesthesiologists score, type of surgery, operative time, operative complications and intraoperative or postoperative transfusion. Estimated blood loss was lower using reduced-port approach. VAPS at postoperative day one was significantly lower for 2-port approach and so was the length of stay. Patient satisfaction with the wound was higher for 2-port surgery. Differences were not observed in number and severity of postoperative complications. CONCLUSIONS Urological reconstructive operations can be safely performed using the hybrid laparoendoscopic single-site umbilical approach, resulting in lower blood loss, higher patient satisfaction and lower postoperative pain, which also facilitate earlier hospital discharge, than the same reconstructive procedures performed through multiport conventional laparoscopy.

Abstract
CONTEXT Robotic surgery is rapidly evolving and has become an essential part of surgical practice in several parts of the world. Robotic technology will expand globally and most of the surgeons around the world will have access to surgical robots in the future. It is essential that we are updated about the outcomes of robot assisted surgeries which will allow everyone to develop an unbiased opinion on the clinical utility of this innovation. OBJECTIVE In this review we aim to present the evolution, objective evaluation of clinical outcomes and future perspectives of robot assisted urologic surgeries. ACQUISITION OF EVIDENCE A systematic literature review of clinical outcomes of robotic urological surgeries was made in the PUBMED. Randomized control trials, cohort studies and review articles were included. Moreover, a detailed search in the web based search engine was made to acquire information on evolution and evolving technologies in robotics. SYNTHESIS OF EVIDENCE The present evidence suggests that the clinical outcomes of the robot assisted urologic surgeries are comparable to the conventional open surgical and laparoscopic results and are associated with fewer complications. However, long term results are not available for all the common robotic urologic surgeries. There are plenty of novel developments in robotics to be available for clinical use in the future. CONCLUSION Robotic urologic surgery will continue to evolve in the future. We should continue to critically analyze whether the advances in technology and the higher cost eventually translates to improved overall surgical performance and outcomes.
