Purpose: Radical antegrade modular pancreatosplenectomy (RAMPS) was first introduced in 2003. It has been accepted as an alternative technique for pancreatic cancer of the body and tail. However, robotic RAMPS is not yet popular because of its technical difficulty and lack of standardized technique. This study describes in detail the standard steps of robotic RAMPS using the flip-up approach with the benefit of a robotic view when treating pancreatic cancer of the body and tail.
Method: We took advantage of our single-center experience to provide a step-by-step technique of robotic RAMPS procedure using the da Vinci Si system.
Results: We divided the procedure into 11 key steps. The surgical steps are optimized to achieve margin-negative curative resection and sufficient regional lymphadenectomy. The artery-first approach is usually used to determine tumor resectability early before performing an irreversible operative step. We also determine the borders of surgical resection and divide the splenic artery after dividing the pancreatic neck and the splenic vein, which facilitates a complete lymphadenectomy around the celiac axis with a bottom-up view.
Conclusion: Robotic RAMPS using the flip-up approach is safe and feasible in performing curative resection for well-selected pancreatic cancer of the body and tail. A randomized controlled trial comparing open and robotic RAMPS is needed in the future.

Prosthetic knees represent a prevalent solution for above-knee amputation rehabilitation. However, satisfying the ambulation requirements of users while achieving their comfort needs in terms of lightweight, bionic, shock-absorbing, and user-centric, remains out of reach. Soft materials seem to provide alternative solutions as their properties are conducive to the comfort aspect.

Background And Objectives: Lower-limb wearable devices can significantly improve the quality of life of subjects suffering from debilitating conditions, such as amputations, neurodegenerative disorders, and stroke-related impairments. Current control approaches, limited to forward walking, fall short of replicating the complexity of human locomotion in complex environments, such as uneven terrains or crowded places. Here we propose a high-level controller based on two Support Vector Machines exploiting four surface electromyography (EMG) signals of the thigh muscles to detect the onset (Toe-off intention decoder) and the direction (Directional EMG decoder) of the upcoming step.

Purpose: We describe details and outcomes of a novel technique for optimizing the surgical field during robotic distal pancreatectomy (RDP) for distal pancreatic lesions, which has become common with potential advantages over laparoscopic surgery.
Methods: For suprapancreatic lymph node dissection and splenic artery ligation, we used the basic center position with a scope through the midline port. During manipulation of the perisplenic area, the left position was used by moving the scope to the left medial side.

Understanding the natural biomechanics of walking at different speeds and activities is crucial to develop effective assistive devices for persons with lower-limb impairments. While continuous measures such as joint angle and moment are well-suited for biomimetic control of robotic systems, whole-stride summary metrics are useful for describing changes across behaviors and for designing and controlling passive and semi-active devices. Dynamic mean ankle moment arm (DMAMA) is a whole-stride measure representing the moment arm of the ground reaction impulse about the ankle joint-effectively, how "forefoot-dominated" or "hindfoot-dominated" a movement is.
