Tegra Medical Is Using Automation to Transform Tissue Shaver Manufacturing
As minimally invasive procedures continue to grow across orthopaedics, gynecology and other specialties, tissue shavers have become indispensable surgical instruments. Their ability to precisely remove diseased or damaged tissue while preserving surrounding healthy anatomy helps support improved clinical outcomes.
According to Strait Research, the global market for arthroscopic shavers alone is projected to grow from USD 1.42 billion in 2026 to USD 1.87 billion by 2034.
As manufacturers ramp up to meet demand, they grapple with the following challenge: How do you scale production of highly engineered devices without sacrificing precision, consistency or quality?
What Makes Tissue Shavers Challenging To Manufacture?
Understanding what makes tissue shavers difficult to manufacture starts with understanding how they work.
A tissue shaver comprises a hollow inner tube that rotates within a hollow outer tube. Each tube has a closed distal tip with a window where a geometrically designed blade cuts and removes tissue. During surgery, with each rotation of the inner tube, the cutting geometry removes tissue and sucks it through the hollow tube and out of the body to repair tissues and joints while preserving healthy structures.
Although tissue shavers may appear deceptively simple, they combine multiple precision-manufactured components that must work together flawlessly.
The manufacturing of these shavers share a common key feature: A machined tip is laser welded onto a tube. Joining the precision-machined cutting tip to the tube is one of the most critical manufacturing steps. Any variation in alignment, weld integrity or straightness can affect rotational performance, cutting efficiency and device reliability.
How Tegra Medical Leveraged Automation To Scale Production and Ensure Precision
Traditional manufacturing approaches often rely on skilled manual operations for alignment, welding and inspection. While effective at lower volumes, these methods become increasingly difficult to scale while maintaining consistency.
To meet increasing demand while maintaining precision, Tegra Medical’s Automation Engineering team, in close collaboration with the customer, developed an innovative automated welding solution.
Value Engineering Principles at Work
From design-for-manufacturability through product delivery, Tegra Medical is guided by the three pillars of value engineering. The proprietary tissue shaver automation cell exemplifies these principles while integrating automated component feeding, precision fixturing, laser welding and digital inspection into a streamlined manufacturing flow.
- Optimizing the product: Tips and tubes are automatically loaded and positioned for welding, supporting consistency along the full 360o seam. Improving the fitment between the two parts eliminates the chances of failure in field, such as breakage of the weld or seizing of the device during a medical procedure. Uniformly high manufacturing standards support reliability and durability, while reducing vibration at high RPMs.
- Improving the processes: Three simultaneous laser tack welds improve alignment and straightness. Automated digital inspection verifies critical quality characteristics before completed parts are sorted, reducing manual intervention while increasing throughput and process consistency.
- Leveraging advantages of digitization: The automated welding solution leverages digital technologies, including 3D printing, tooling and fixture simulations, and automated inspection.
Our satisfied customers enjoy the following benefits:
- Better on-time delivery due to manufacturing improvements
- Cost reduction through automated, stabilized processes
- Improved sustainability thanks to reduced scrap and reduced CO2 emissions
