INDUSTRIES  Medical Devices |
| |
InDepth has had the opportunity to contribute towards healthcare system by applying our design, engineering and simulation knowledge to the development of following modern-day medical devices.
|
| |
SURGICAL STAPLER |
| |
- These staplers are used in minimally invasive robot-assisted surgical systems
- Our scope was to assess the durability performance of Drive Cam and Pivot Mechanism
- Finite Element Model setup was done using Hypermesh and solved in Abaqus/Standard, while accounting for material and geometric nonlinearities
- Evaluated various drive cam and pivot designs subjected to abuse load cases
- Alternate material choices were also explored and provided design direction to improve performance
|
| |
SURGICAL GRIP |
| |
- These grips are also used in minimally invasive robot-assisted surgical systems
- Our scope was to investigate cracking issues in over-molded plastic on a Metal Injection Molded (MIM) grip
- For quick turnaround, SolidWorks simulations was implemented
- Proposed/compared performance of various design options and directed client’s design team towards promising solutions
|
| |
HOME EXTERNAL COUNTER-PULSATION (ECP) DEVICE |
| |
- Typically, ECP is a non-invasive outpatient therapy to treat Angina
- The focus of this project was to develop a compact/portable ECP device for home usage
- Our approach was to explore following three pneumatic system concepts:
- Complete metal (Aluminum and steel) design
- Metal and high strength plastic design
- Complete high strength plastic design
- Achieved about 30% mass savings (compared to complete metal design) by using advanced simulation/optimization tools such as Nastran and OptiStruct
