Front Robot AI 2024; 11:1400017. [PMID: 38899064 PMCID: PMC11186318 DOI: 10.3389/frobt.2024.1400017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Accepted: 05/13/2024] [Indexed: 06/21/2024] Open
Abstract
The Expanded Endoscopic Endonasal Approach, one of the best examples of endoscopic neurosurgery, allows access to the skull base through the natural orifice of the nostril. Current standard instruments lack articulation limiting operative access and surgeon dexterity, and thus, could benefit from robotic articulation. In this study, a handheld robotic system with a series of detachable end-effectors for this approach is presented. This system is comprised of interchangeable articulated 2/3 degrees-of-freedom 3 mm instruments that expand the operative workspace and enhance the surgeon's dexterity, an ergonomically designed handheld controller with a rotating joystick-body that can be placed at the position most comfortable for the user, and the accompanying control box. The robotic instruments were experimentally evaluated for their workspace, structural integrity, and force-delivery capabilities. The entire system was then tested in a pre-clinical context during a phantom feasibility test, followed up by a cadaveric pilot study by a cohort of surgeons of varied clinical experience. Results from this series of experiments suggested enhanced dexterity and adequate robustness that could be associated with feasibility in a clinical context, as well as improvement over current neurosurgical instruments.

Abstract
BACKGROUND An accurate and objective measuring tool is lacking for laparoscopic suture accuracy assessment in simulation training. We designed and developed the suture accuracy testing system (SATS) and aimed to determine its construct validity in this study. METHODS Twenty laparoscopic experts and 20 novices were recruited to perform a suturing task in three sessions using traditional laparoscopic instruments (Tra. session), a handheld multi-degree-of-freedom (MDoF) laparoscopic instrument (MDoF session) and a surgical robot (Rob. session), respectively. The needle entry and exit errors were calculated using the SATS and compared between the two groups. RESULTS No significant difference of the needle entry error was found in all comparisons. As for the needle exit error, the value of the novice group was significantly higher than that of the expert group in Tra. session (3.48 ± 0.61 mm vs. 0.85 ± 0.14 mm; p = 1.451e-11) and MDoF session (2.65 ± 0.41 mm vs. 1.06 ± 0.17 mm; p = 1.451e-11) but not in Rob. session (0.51 ± 0.12 mm vs. 0.45 ± 0.08 mm; p = 0.091). CONCLUSIONS The SATS demonstrates construct validity. Surgeons' experience in conventional laparoscopic instruments could be transferred to the MDoF instrument. Surgical robot helps to improve suture accuracy and may bridge the experience gap between laparoscopic experts and novices in basic exercises.

Abstract
Abstract
Because of the increasing use of laparoscopic surgeries, robotic technologies have been developed to overcome the challenges these surgeries impose on surgeons. This paper presents an overview of the current state of surgical robots used in laparoscopic surgeries. Four main categories were discussed: handheld laparoscopic devices, laparoscope positioning robots, master–slave teleoperated systems with dedicated consoles, and robotic training systems. A generalized control block diagram is developed to demonstrate the general control scheme for each category of surgical robots. In order to review these robotic technologies, related published works were investigated and discussed. Detailed discussions and comparison tables are presented to compare their effectiveness in laparoscopic surgeries. Each of these technologies has proved to be beneficial in laparoscopic surgeries.

Abstract
Background: Enhanced laparoscopic instruments are filling the gap between straight-stick laparoscopic equipment and robotic platforms. We sought to evaluate the performance and cost of the HandX™ device during mesh fixation and peritoneal flap closure of transabdominal preperitoneal (TAPP) inguinal hernia repairs. Methods: The video recordings of a consecutive series of TAPP surgeries using the articulated needle driver device were compared with a series of surgeries on the DaVinci robotic platform by a single surgeon. Two critical steps of the procedure were analyzed: mesh fixation and peritoneal closure. A cost analysis between the two platforms was completed. Results: We analyzed 27 cases using the new needle driver and 27 cases using the DaVinci Surgical Robotic system. To evaluate the learning curve (LC) with the HandX device, we created three groups (G1, G2, and G3). The two latter groups were combined and called after LC. Mean fixation time using the DaVinci system was 258.1 seconds (±100.4) compared with 391.5 (±95.9) using the articulating handheld laparoscopic needle driver after LC (P < .001). The average time for peritoneal closure was 418.6 (±192.1) seconds for DaVinci and 634.5 (±159.5) seconds for HandX (P < .001). When comparing the after-LC HandX cases and the DaVinci system stratified by side, there was no significant difference in peritoneal closure in the right side (520.1 seconds (84.3) with the HandX versus 444.2 seconds (229.7) using the DaVinci system (P = .353). When evaluating direct cost of the instruments, HandX cases had a lower cost (310 USD) when compared with the cost of using DaVinci (973 USD). Conclusions: The new smart articulating needle driver may be a cost-effective means of bringing some of the benefits of the robotic platform to laparoscopy.

Abstract
Endoscopic endonasal skull base surgery is a promising alternative to transcranial approaches. However, standard instruments lack articulation, and thus, could benefit from robotic technologies. The aim of this study was to develop an ergonomic handle for a handheld robotic instrument intended to enhance this procedure. Two different prototypes were developed based on ergonomic guidelines within the literature. The first is a forearm-mounted handle that maps the surgeon's wrist degrees-of-freedom to that of the robotic end-effector; the second is a joystick-and-trigger handle with a rotating body that places the joystick to the position most comfortable for the surgeon. These handles were incorporated into a custom-designed surgical virtual simulator and were assessed for their performance and ergonomics when compared with a standard neurosurgical grasper. The virtual task was performed by nine novices with all three devices as part of a randomised crossover user-study. Their performance and ergonomics were evaluated both subjectively by themselves and objectively by a validated observational checklist. Both handles outperformed the standard instrument with the rotating joystick-body handle offering the most substantial improvement in terms of balance between performance and ergonomics. Thus, it is deemed the more suitable device to drive instrumentation for endoscopic endonasal skull base surgery.

Abstract
Technology is one of the pillars of surgery in the 21st century and is a key factor in achieving better surgical results. The current surgical process involves not only surgical techniques, but also a very high degree of specialisation and the knowledge and use of techniques and devices from other fields. In Spain, there are no studies published at a national level in this regard. From the Minimally Invasive Surgery and Technological Innovation section of the Spanish Association of Surgeons we have designed a study whose main objective is to evaluate the degree of technological implantation in the specialty of General Surgery in Spain, as well as to analyze the devices available in the different centres of the country. We propose to make a detailed description of the applications of these devices and techniques by areas of interest, pointing out the pathologies and procedures in which this technology is used.

Abstract
BACKGROUND Handheld robotic laparoscopic instruments fill the gap between robotic and conventional instruments, combining the advantages of degrees of freedom and low price. The difficulty and value in learning these new instruments require detailed investigation. METHODS Forty novice surgeons with no laparoscopic experience were randomly assigned to two groups: conventional instrument group (Group Conv) and robotic instrument group (Group Rob). The same training protocol was used in both groups: after viewing a standard operation film, laparoscopic suture training was administered using the corresponding instruments. After each training period, surgeons were tested using a force-sensing test platform. Maximum force (MF) and impulse (IMP) of operators through each ring were recorded. Learning curves based on MF and IMP for both instruments were compared. Institutional review board approval is not needed for this study. RESULTS MF and IMP of both groups decreased with increased training time; the learning curve of Group Conv decreased faster than that of Group Rob. When training time reached 13 h, the MF of Group Rob was significantly lower than that of Group Conv (P < 0.05), while IMP showed no significant difference between the two groups. CONCLUSIONS Effective training reduces operator MF and IMP, possibly decreasing damage to tissues with both conventional and handheld robotic needle holders. Group Rob took longer to reach a plateau, but subsequently had lower suture tension than did Group Conv. MF is more sensitive than IMP for measuring performance progress.
