Mechanical Design for Medical Devices

Engineering the Mechanism Behind the Device

Powered surgical tools live or die by their mechanics: a drill that runs at 120,000 RPM, a saw that holds millimeter accuracy on a robot arm. Zlinemed’s mechanical design service brings that level of engineering to client devices — the same discipline that produced our own surgical power tool platforms.

What the Service Covers

Mechanical Principle Architecture Development

System-level functional decomposition and mechanical concept definition based on product requirements — deciding how the device works before deciding how it looks inside.

Transmission System Design

Design of gear trains, linkages, cam systems, precision shafts, and high-speed drive mechanisms tailored to performance targets.

Engineering Simulation & Verification

Structural strength, deformation, fatigue life, and dynamic response analysis using FEA and related validation tools — failure modes found in simulation, not in the field.

3D Mechanical Design

Parametric modeling, tolerance stack-up design, and assembly architecture optimization, producing models that manufacturing can trust.

2D Engineering Drawings

Complete production drawings with GD&T, tolerance control, and manufacturing standards — unambiguous instructions for any qualified supplier.

Functional Prototype Development

Rapid prototyping and functional sample validation for performance, durability, and manufacturability assessment.

Part of an Integrated Development Chain

Mechanical design works hand-in-hand with industrial design upstream and circuit design downstream, under one roof. For full product programs, see medical device development.
