Device Prototype for Vaginal Delivery of Extremely Preterm Fetuses in the Breech Presentation
(The American Society of Mechanical Engineers (ASME), 2020)Vaginal delivery is typically avoided in the extremely preterm breech population due to the concern of entrapment by the cervix of the aftercoming head. A mechanical device concept is presented to enable vaginal delivery ... -
Characterization of Acetabular Cup Insertion Forces in Cancellous Bone Proxy for Validation of an Invasive Sensing Model and Development of Automatic Prosthesis Installation Device: A Preliminary Study
(The American Society of Mechanical Engineers (ASME), 2020)Total hip replacement is a widespread medical procedure, with over 300,000 surgeries performed each year in the United States alone. The vast majority of total hip replacements utilize press fit fixation. Successful seating ... -
A Double-Walled Assistive Holder Used in Peritoneal Dialysis Connection
(The American Society of Mechanical Engineers (ASME), 2021)When compared with conventional kidney hemodialysis, peritoneal dialysis (PD) has advantages such as maintaining stable physiological blood status and blood pressure, alleviating anemia, and improving mobility, which make ... -
RailBot: A Novel Assistive Device for Stair Climbing
(The American Society of Mechanical Engineers (ASME), 2021)For most older adults, their own homes is the overwhelmingly preferred environment for living and growing older. However, for those living in homes with stairs, the difficulty and risk of injury in stair ascent/descent is ... -
Application-Specific Learning Curve With a Modern Computer-Assisted Orthopedic Surgery System for Joint Arthroplasty
(The American Society of Mechanical Engineers (ASME), 2021)A commonly acknowledged barrier for the adoption of new computer-assisted orthopedic surgery (CAOS) technologies relates to a perceived long and steep learning curve. However, this perception has not been objectively tested ... -
