RISAn Analytical Model for Pitch Moment Stiffness of Bolted Connections and Its Application in Ballscrew Bearing Support Block Selection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bolted joints are commonly used structural connections as they provide a strong secure joint along with ease of assembly/disassembly. While analytical models for the axial stiffness of bolted joints are well developed, ...
A Buckling Flexure-Based Force-Limiting Mechanism
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: A force-limiting buckling flexure has been created which can be used in a wide range of applications where excessive force from an implement can cause harm or damage. The buckling flexure is monolithic, contains no ...
A C-3 Clamp for Improved Connection Between Catheter Tube and Barbed Connector Together With Its Evaluation Using a Maximum Pull-Off Force Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The majority of hospitalized patients require the insertion of a catheter as part of their medical treatment. For catheters to be connected to external devices, barbed connectors are often employed. If this connection is ...
Ring-Based Stiffening Flexure Applied as a Load Cell With High Resolution and Large Force Range
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper applies linear elastic theory and Castigliano's first theorem to design nonlinear (stiffening) flexures used as load cells with both large force range and large resolution. Low stiffness at small forces causes ...
A Retractable Six-Prong Laparoscopic Grasper for Laparoscopic Myomectomy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fixation and manipulation of fibroids during laparoscopic myomectomy is a persistent issue for gynecologic surgeons. In this paper, we present a laparoscopic grasper that, through a sheath-based deployment mechanism, ...
Device Prototype for Vaginal Delivery of Extremely Preterm Fetuses in the Breech Presentation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
Toolpath Planning for Manufacturing of Complex Parts Through Incremental Sheet Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Incremental sheet forming (ISF) offers great flexibility in producing complex sheet parts as compared with conventional sheet forming processes where part-specific die sets are required to form a product. While there are ...
Design of a Device to Ease and Improve the Diagnosis of Popliteal Artery Entrapment Syndrome
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Popliteal artery entrapment syndrome (PAES) is a condition affecting blood flow in the back of the leg, which can have a significant impact on the patient's life. It is often misdiagnosed due to a lack of standardized ...
LesionAir: An Automated, Low-Cost Vision-Based Skin Cancer Diagnostic Tool
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current techniques for diagnosing skin cancer lack specificity and sensitivity, resulting in unnecessary biopsies and missed diagnoses. Automating tissue palpation and morphology quantification will result in a repeatable, ...
A Novel Approach to Open Reduction and Internal Fixation of Distal Radius Fractures Utilizing a Multi-Degree-of-Freedom Traction and Stabilization Device
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Open reduction and internal fixation (ORIF) is a surgical procedure performed with the objectives of restoring normal alignment and providing stability to broken bone fragments after a fracture. This procedure is increasingly ...
