“…Performance outcomes were measured using a quantitative and qualitative score, and skills outcomes were measured by the number of movements and the path length traveled by the instrument. The RULA method was used for the surgeon's postural analysis [2,25]. Muscular activity was assessed by means of electromyography of six muscular groups.…”

“…The use of surgical ports creates a pivot point for the instruments in the body wall, which reduces the degrees of freedom (DoF) of the surgical instruments, from six (free motion) in conventional surgery to four in laparoscopic surgery, as illustrated in Figure 1. Besides, laparoscopic instruments suffer from ergonomically inadequate handle designs and inefficient transmission of force and tactile feedback from the handle to the instrument tip [1,2].…”

“…All the aforementioned restrictions of surgeons' dexterity, in conjunction with the performance of repetitive tasks and the adoption of awkward and static postures during surgery, contribute to the onset of muscular fatigue and other musculoskeletal problems [2][3][4].…”

Despite the well-known benefits of minimally invasive surgery (MIS) to the patients, this surgical technique implies some technical challenges for surgeons. These technical limitations are increased with the introduction of laparoendoscopic single-site (LESS) surgery. In order to overcome some of these technical difficulties, new handheld devices have been developed, providing improved functionalities along with precision-driven and articulating instrument tips. In this chapter, we will review the current status of handheld devices for laparoscopy and LESS surgery. Devices that provide additional and innovative functionalities in comparison with conventional surgical instruments will be considered. Results will be based on studies published in the scientific literature and our experience. These surgical devices will be organized into two main groups, mechanical devices and robotic-driven devices. In general, these instruments intend to simulate the dexterity of movements of a human wrist. Mechanical devices are cheaper and easier to develop, so most of the available handheld instruments fall into this category. The majority of the robotic-driven devices are needle holders with an articulating tip, controlled by an interface implemented on the instrument handle. In general, these handheld devices claim to offer an enhancement of dexterity, precision, and ergonomics.

Summary. Aim of work: to determine and compare the level of visualization, comfort, safety and effectiveness of simultaneous technique of laparoscopic surgery of gallstone disease and concomitant hiatal hernia and standard «baseball diamond» technique of laparoscopic surgery of only hiatal hernia. Materials and methods: the study was performed based on data developed in MISU VRCH. 359 patients were treated and divided on two groups, of which the group №1 — patients who underwent simultaneous laparoscopic cholecystectomy and cruroraphy with Toupet fundoplication (n=155), and group №2 — patients who underwent only laparoscopic crurography with with Toupet fundoplication. The level of visualization, comfort, frequency of «fencing», duration of operation, length of hospital stay, complication frequency were determined. The method with the null hypothesis, Pearson’s analysis, Mann-Whitney method were used. The results of the study: the approach distance of the laparoscope was (8,11 ± 0,917) and (8,71 ± 0,256) cm for 30°-optics while (6,55 ± 0,491) and (6,66 ± 0,485) cm for 0°-optics in two groups, respectively. The frequency of fencing was just about 4 episodes in both groups and did not differ statistically significantly. The frequency of the need to change the viewing area` and the frequency of the need to change the position of the instruments did not differ statistically significantly in both groups. The operation time was longer in the group of simultaneous operations by 10 % or 4,24 minutes. The level of complications was comparable in both groups, no correlation was found. The length of hospital stay was (3,64 ± 0,71) days (2-8 days) versus (3,58 ± 0,67) days (2-8 days) for both groups, respectively (p = 0.967).

“…In order to address some of these technical limitations, new surgical instruments and devices have been developed aiming to enhance the dexterity, accuracy, and ergonomics of laparoscopic instruments [5]. In addition, new methodological approaches and instrumental techniques for ergonomic analysis have been implemented to improve the working conditions of surgeons, as well as the design of the laparoscopic material [6].…”
