“…The expert surgeons displayed lower hand tremor, VF, IF, and operation force values than the novice surgeons. These findings are consistent with results in 20,21 and seem to indicate that the operation behaviours of experts is more stable than novice surgeons. In terms of hand tremor, the MAX amplitude of novices are 35.18 μm ( X S ), 39.14 μm ( Y S ), and 38.24 μm ( Z S ) larger than experts.…”

Background Continuous curvilinear capsulorhexis (CCC) is a delicate ophthalmic procedure which may benefit from robot technology. Measuring the behaviours (physiological tremor, operation force) of surgeons provides baseline data to develop assistive CCC robot. Methods A forceps with fibre bragg grating and inertial sensors is used to measure the surgeons' behaviours while experts/novices perform CCC on ex‐vivo pig eyes, in‐vivo rabbit eyes and ex‐vivo human lens. Results In pig/rabbit tests, the root‐mean‐square (RMS) tremor amplitude is 35.26/59.04 μm (expert/novice, transverse), 13.3/20.55 μm (axial). The RMS voluntary force (VF) and involuntary force (IF) are 8.97/17.16 mN, and 0.66/1.90 mN, respectively. In human lens test, the RMS tremor amplitude is 24.0 μm (transverse, expert only), 9.88 μm (axial). The RMS VF and RMS IF are 9.04 mN (expert only) and 0.17 mN, respectively. Conclusions The expert surgeons have better precision and less operation force.

ArtiSential® Articulated Wrist-Like Instruments and Their First Application in Pediatric Minimally Invasive Surgery: Case Reports and Literature Review of the Most Commonly Available Robot-Inspired Devices

et al. 2021

Background: Robotic surgery is currently a reality in surgical practice, and many endeavors have been made to extend its application also in pediatric surgery. In the absence of easy access to a robotic surgical system, new devices have been developed to offer a valid alternative such as wristed instruments. These differ from conventional laparoscopic instruments owing to a wrist-like mechanism at the tip, which faithfully reproduces the movements of the surgeon’s hands, regaining more movement’s degrees; Methods: We present two case reports in which the patients were subjected to minimally invasive procedures with aid of wristed instruments, followed by a review of the literature regarding the devices commonly marketed; Results: Articulated or wristed instruments render the same features seen in robotic surgery, such as major dexterity in smaller spaces, restitution of more natural movements and the ability to get over obstacles in a direct visual line. Our center recently equipped with ArtiSential® articulated instruments and so far, they have proven to be of great value; Conclusions: wristed instruments could represent a standpoint for surgeons wanting to benefit from the advantages of robotic surgery with a cost-sensitive perspective.

“…These notable technical difficulties also led to longer learning curves, which surgeons should consider when SILS procedures will be adopted, as opposed to the multiport techniques. The use of articulating instruments was described to reduce intraoperative difficulties [ 49 ]. However, flexible and steerable laparoscopic instruments need to be managed properly, and a learning curve should be expected by both novice and expert surgeons [ 50 ].…”

In veterinary surgery, single incision laparoscopic surgery (SILS) techniques have been described since 2009, and, in recent decades, many authors have reported the application of SILS in small animals, thus, promoting the wide dissemination of this novel approach among veterinary laparoscopists. The aim of this literature review is to provide a critical evaluation of the scientific reports on SILS in the field of small animal laparoscopic surgery. A comprehensive literature review was performed including from 1 January 2009 to 1 July 2020. The following data were recorded from each study: the design, year of publication, surgical procedure, species, number of animals included, and surgical time. The type of SILS technique and type of control group technique were evaluated. In total, 90 articles were identified through database searches and manual searches. The qualitative analysis showed that most of the articles were retrospective studies, without a control group or case series. A meta-analysis was performed on the eight controlled studies, showing that SILS ovariectomy and gastrointestinal procedures had a comparable surgical time to multiport techniques. The study of the articles available in the veterinary literature did not allow for an adequate meta-analysis of the published results, especially regarding post-operative pain, evaluations of surgical times, and post-operative complications in comparison to multiport techniques. Therefore, veterinary surgeons who want to employ these techniques must consider the real advantages of SILS techniques.
