Two-Segment Flexible Macintosh Laryngoscope to Improve Glottic Visualization During Endotracheal Intubation
(The American Society of Mechanical Engineers (ASME), 2021)Endotracheal intubation is a frequently performed life-saving procedure in medicine. Obtaining view of glottic structures is essential for successful completion of endotracheal intubation. Most frequently used devices ... -
Workflow-Based Design and Evaluation of a Device for CBCT-Guided Biopsy
(The American Society of Mechanical Engineers (ASME), 2021)Biopsies for personalized cancer care can be performed with cone beam computed tomography (CBCT) guidance, but manual needle manipulation remains an issue due to X-ray exposure to physicians. Modern CBCT scanners integrate ... -
Research on Biomechanical Compatibility for the Artificial Anal Sphincter Based on Improved Actuator
(The American Society of Mechanical Engineers (ASME), 2021)Anal incontinence, also known as fecal incontinence, refers to the loss of the body's ability to accumulate and control the liquid, solid, and gas contents in the rectum, increasing the frequency of bowel movements. It is ... -
A Proof-of-Principle Study of the Design and Optimization of a Novel Fluid-Driven Automated Retracting Needle System
(The American Society of Mechanical Engineers (ASME), 2021)The cannulation of blood vessels is one of the most basic and essential interventions in medical practice. A common adverse event of this procedure is miscannulation with infiltration of the second part of the vessel wall, ... -
The Design and Development of an Eye Drop Aid for Glaucoma Patients
(The American Society of Mechanical Engineers (ASME), 2021)Visual impairment is an important public health problem. A cataract is the most common eye disease, and surgical methods are mostly used. Unlike a cataract, glaucoma may lead to permanent loss of vision and can be treated ... -
Clinical Translation of an Insertion Tool for Minimally Invasive Cochlear Implant Surgery
(The American Society of Mechanical Engineers (ASME), 2021)The objective of this paper is to describe the development of a minimally invasive cochlear implant surgery (MICIS) electrode array insertion tool concept to enable clinical translation. First, analysis of the geometric ... -
Generic Implant Positioning Technology Based on Hole Projections in X-Ray Images
(The American Society of Mechanical Engineers (ASME), 2021)Implant placement plays a key role in trauma and orthopedics. In this paper, a generic technological concept for implant positioning assistance is outlined. The system utilizes conventional radiographic devices for imaging ... -
Design Synthesis and Preliminary Evaluation of a Novel Tool to Noninvasively Characterize Pressurized, Physiological Vessels
(The American Society of Mechanical Engineers (ASME), 2020)A prolonged increase in intra-abdominal pressure (IAP) is life-threatening, yet commonly seen in intensive care units (ICUs). Despite this, existing clinically accepted IAP measurement techniques are invasive and not ... -
A Novel Suction-and-Irrigation Laparoscopic Surgical Instrument: Internal Design and Preclinical Performance Evaluation
(The American Society of Mechanical Engineers (ASME), 2021)Objective: Laparoscopic instruments with suction and irrigation functions often lead to tissue damage during removal of the aspirated tissues, owing to the presence of aspiration into the side holes of their catheters. To ... -
Design and Fabrication of Custom-Fit BiPAP and CPAP Masks Using Three-Dimensional Imaging and Three-Dimensional Printing Techniques
