Abstract:

Tendon-driven endoscopes are mainly used in the current practice. Their flexible bodies may change frequently during the processes of biopsy, endoscopic mucosal resection or endoscopic submucosal dissection. These changes lead to backlash hysteresis and nonlinear friction effects, which make it difficult to achieve accurate control. To address this problem, a mixed control scheme based on the combination of discrete and continuous models was proposed and quantitatively compared with a conventional feedback control scheme, a feedforward control scheme and an adaptive control scheme. These exper

Abstract:

Abstract The manipulation of flexible endoscopes is a procedure that requires great dexterity since it requires the synchronization and use of both hands in parallel. Imprecise handling during gastroendoscopy could harm the digestive tract. Our solution allows the physician to use only one hand to wirelessly control the forward, backward, and tip bending motion. The proposed system provides endoscopic vision and tactile impact force sensing at the tip to detect the force applied to tissue and thus avoid damage. We experimentally evaluate the handling of the robotic system in open space and ins

Abstract:

Due to the technical improvements in endoscopes and armamentarium, flexible ureterorenoscopy (fURS) has increased in the management of nephrolithiasis over the last decade. fURS is a challenging procedure and therefore limited in some regions. To overcome these challenges, a master-slave robotic system might help dominate fURS. As with other robotic systems, the ergonomic deficits of fURS play an important role in the development of a new robot. All ureterorenoscopy (URS) robots thus far consist of a surgeon’s console and the manipulator of a flexible ureterorenoscope. Handling and maneuverabi

Abstract:

Variable rigidity materials that are safe, controllable, reversible, and repeatable have potentially widespread implications in robotic technologies. This paper presents a method for controlling the stiffness of materials for compliant tools, such as grippers, soft robots, and endoscopes. The force of electromagnetic suction transforms two structures from their relaxed-state into a more rigid state. The system presented here has the ability of quickly increasing the stiffness with increased current in the coils that create electromagnetic suction, wherein the stiffness can be controlled by the

Abstract:

Objectives: The hybrid supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCPL-CHEP, that is, open partial horizontal laryngectomies OPHL Type IIa) has been described using a flexible next generation robotic surgical platform for manipulation. We sought to evaluate the feasibility of performing this procedure using endoscopic transoral (EndoT) surgical techniques without robotics. Methods: Preclinical cadaveric study using two human cadavers. Hybrid SCPL-CHEP was performed with a flexible endoscope for visualization and hand-held instruments for manipulation (SILS Hook monopolar

Abstract Purpose of Review Gastrointestinal endoscopy includes a wide range of procedures that has dramatically evolved over the past decades. Robotic endoscopy and artificial intelligence are expanding the horizons of traditional techniques and will play a key role in clinical practice in the near future. Understanding the main available devices and procedures is a key unmet need. This review aims to assess the current and future applications of the most recently developed endoscopy robots. Recent Findings Even though a few devices have gained approval for clinical application, the majority o

Abstract:

318 Background: Effective traction and counter-traction for visualizing the dissection plane in endoscopic submucosal dissection (ESD) is difficult to be achieved with a conventional endoscope. We developed a robotic assistive traction device for flexible endoscopy that provides multi-directional traction during ESD. We compared its safety and efficiency in ESD between experienced and novice endoscopists. Methods: Robotic ESD was performed by experienced and novice endoscopist groups (n = 2, each). The outcomes included time to complete each ESD step, total procedure time, size of the dissecte

Abstract:

Early-stage gastrointestinal cancer is often treated by endoscopic submucosal dissection (ESD) using a flexible endoscope. Compared with conventional percutaneous surgery, ESD is much less invasive and provides a high quality of life for the patient because it does not require a skin incision, and the organ is preserved. However, the operator must be highly skilled because ESD requires using a flexible endoscope with energy devices, which have limited degrees of freedom. To facilitate easier manipulation of these flexible devices, we developed a surgical robot comprising a flexible endoscope a

Abstract:

Flexible colonoscopy remains the prime mean of screening for colorectal cancer (CRC) and the gold standard of all population-based screening pathways around the world. Almost 60% of CRC deaths could be prevented with screening. However, colonoscopy attendance rates are affected by discomfort, fear of pain and embarrassment or loss of control during the procedure. Moreover, the emergence and global thread of new communicable diseases might seriously affect the functioning of contemporary centres performing gastrointestinal endoscopy. Innovative solutions are needed: artificial intelligence (AI)

Abstract:

AbstractSince the introduction of transanal endoscopic microsurgery, local excision of “early” rectal lesions has offered the possibility to reduce the invasiveness of treatment for the limited disease. Flexible endoscopy techniques allow today different alternatives consisting of endoscopic mucosal resection or endoscopic submucosal dissection. The first is a straightforward and relatively easy technique, but it prevents a correct pathological staging of the lesion due to fragmentation and the verification of disease-free margins. The second relies on operators' audacity depending on their in
