A New Concept of Needle-Free Jet Injector by the Impact Driven Method
(The American Society of Mechanical Engineers (ASME), 2017)Currently, most of commercial needle-free jet injectors generate the liquid jet by a method called “driving object method” (DOM); however, the reliability and efficiency are still questioned. This paper proposes a new ... -
Design and Evaluation of a Portable Laparoscopic Training System Using Virtual Reality
(The American Society of Mechanical Engineers (ASME), 2017)The ubiquitous nature of laparoscopic surgery and the decreased training time available for surgeons are driving an increased need for effective training systems to help surgeons learn different procedures. A cost-effective ... -
A New Methodology of Finding Optimal Toolpath and Tooling Strategies for Robotic-Assisted Arthroplasty
(The American Society of Mechanical Engineers (ASME), 2017)Robotic total hip arthroplasty is a procedure in which a milling operation is performed on the femur followed by insertion of a prosthetic implant. Although surgeons operate the robots, they do not control the choice of ... -
pneuRIPTM: A Novel Respiratory Inductance Plethysmography Monitor
(The American Society of Mechanical Engineers (ASME), 2017)Objective pulmonary function (PF) evaluation is essential for the diagnosis, monitoring, and management of many pediatric respiratory diseases as seen in the emergency room, intensive care, and outpatient settings. In this ... -
Toward Medical Devices With Integrated Mechanisms, Sensors, and Actuators Via Printed-Circuit MEMS
(The American Society of Mechanical Engineers (ASME), 2017)Recent advances in medical robotics have initiated a transition from rigid serial manipulators to flexible or continuum robots capable of navigating to confined anatomy within the body. A desire for further procedure ... -
Disposable Fluidic Actuators for Miniature In-Vivo Surgical Robotics
(The American Society of Mechanical Engineers (ASME), 2017)Fusion of robotics and minimally invasive surgery (MIS) has created new opportunities to develop diagnostic and therapeutic tools. Surgical robotics is advancing from externally actuated systems to miniature in-vivo robotics. ... -
Hydraulic Robotic Surgical Tool Changing Manipulator
(The American Society of Mechanical Engineers (ASME), 2017)Natural orifice transluminal endoscopic surgery (NOTES) is a surgical technique to perform “scarless” abdominal operations. Robotic technology has been exploited to improve NOTES and circumvent its limitations. Lack of a ... -
Particulate Release From Nanoparticle-Loaded Shape Memory Polymer Foams
(The American Society of Mechanical Engineers (ASME), 2017)Highly porous, open-celled shape memory polymer (SMP) foams are being developed for a number of vascular occlusion devices. Applications include abdominal aortic and neurovascular aneurysm or peripheral vascular occlusion. ... -
A Laparoscopic Morcellator Redesign to Constrain Tissue Using Integrated Gripping Teeth
(The American Society of Mechanical Engineers (ASME), 2017)Laparoscopic hysterectomy is a procedure that involves the removal of the uterus through an abdominal keyhole incision. Morcellators have been specifically designed for this task, but their use has been discouraged by the ... -
Development of Aspiration-Assisted End-Cut Coaxial Biopsy Needles
(The American Society of Mechanical Engineers (ASME), 2017)Needle biopsy procedures, such as fine-needle aspiration and core needle biopsy, are used to extract tissue samples for diagnosis, and collection of larger samples allows for more accurate diagnosis of cancers. The combination ... -
A Novel Approach to Design Lesion-Specific Stents for Minimum Recoil
(The American Society of Mechanical Engineers (ASME), 2017)Stent geometries are obtained by topology optimization for minimized compliance under different stenosis levels and plaque material types. Three levels of stenosis by cross-sectional area, i.e., 30%, 40%, and 50% and three ... -
