Surgical Instruments – Safe, Effective & Compliant Precision Tools

Robust, Simple and Reliable Quality Control (QC) Solutions

Surgical instruments (scissors, stethoscopes, scalpels, forceps, clamps, retractors, etc.) are high-precision tools engineered and manufactured in compliance with stringent quality specifications.

New instruments designed for advanced minimal-invasive and single-incision surgeries – and made of different materials (such as stainless steel, titanium, nylon, teflon, silicon or fiberglass) must make smaller incisions in favor of smaller scars and fewer post-operative complications.

Long-lasting quality and robust performance with low susceptibility to retain bioburden are among the many elements to consider while designing these instruments. During manufacturing, many components must be refined, surface-treated and sometimes assembled by hand. 

Stringent QC is a key factor for successful commercialization of surgical instruments. It offers the potential to de-risk projects, increase success rates, significantly reduce costs and accelerate time-to-market. Deviations or fluctuations can be detected in time to avoid higher production costs, downtimes or product recalls.

Raw Material Testing

The quality of the final product depends on the quality of the raw materials. To ensure device performance and patient safety, your raw materials must be stable and safe for use and meet stringent ISO, USP, EP, ChP, JP, and ARTG testing standards. 

Discover the Raw Material Testing solutions for your application:

  • Density Check of Solid Material & Liquids
  • Moisture Determination of Raw Material
  • Particulate Matter Analysis
  • Chemical Characterization - Biocompatibility
  • Microbial Testing: Water & Bioburden Testing

Frequently Asked Questions

You may have heard the term Six Sigma used in conjunction with lean manufacturing, a Kaizen approach or continuous quality improvement. Six Sigma is not only applicable to large-scale business operations.

If you're looking for a way to improve production processes or solve a quality control problem, Six Sigma might be the answer. Discover more in our Science Snippets Blog.

Prior to sterilization, bioburden testing to determine total number of viable microorganisms on all or part of a medical device surface, is one of the most-used microbiological tests in the Medical Device industry.

As required by industrial standards such as ISO 11737-1, microorganisms should be suspended in the proper liquid, captured using membrane filtration and grown on a culture medium. Thus, using the right products and procedures to determine bioburden is essential and helps reduce risks which could impact patient safety.
