VIDEO: Caring for Your Surgical Instrument Investment: Introduction

What's the difference between cleaning, disinfecting and sterilizing? Let's take a look. This is the first in a series of four videos to discuss some best practices in caring for your surgical instrument investment.

VIDEO: Guide for Ultrasonic Cleaning of Surgical Instruments

Ultrasonic cleaning is the most effective cleaning method for maintaining your surgical instruments, because of its cavitation. Vibrating sound waves create micron-size bubbles in solution that grow as the pressure in the unit changes.

Guide for Manually Cleaning Surgical Instruments

The proper care and handling of surgical instruments is the simplest way to protect your investment and add years to the life of your instruments. Here is a handy infographics showing the steps for proper surgical instrument cleaning.

VIDEO: Stain Guide for Surgical Instruments

Although stainless steel is corrosion-resistant, it can still rust and stain if it is handled improperly. To determine if a discoloration is rust or just a stain, erase the discoloration with a pencil eraser. If there is pitting in the metal under the discoloration, it is corrosion. If the discoloration is removed, it was just a stain. 

VIDEO: How to use the Celloger® Mini Plus Software

VIDEO: Comparison of Metal for Surgical Instruments

Surgical instruments are designed to perform diagnostic, therapeutic, or investigative operations having specific functions such as to cut or incise, retract, grasp, hold or occlude, dilate or probe, suture or ligate. 

MICRO-ePUMP Injection Sequence Explained

Designed to simplify intracellular injection and a variety of other microinjection tasks, the MICRO-ePUMP uses carefully regulated air pressure for injecting cells with fluid. Injected volumes range from picoliters to nanoliters. Timing, injection pressure and compensation pressure are adjusted independently using the touch screen interface. Time intervals can range from 2 seconds down to 10 ms or less, depending on the injection pressure setting. The injection pressure interval is triggered using the foot switch.

Understanding the Types of Stainless Steel for Manufacturing Surgical Instruments

Two main criteria to be considered when choosing your surgical instruments are the quality of the steel and the manufacturing process itself. Manufacturing quality instruments involves standards for various aspects of the manufacturing process, including the basic requirements for quality steel, as well as vigorous inspection for every step on the process. Here is a handy infographic comparing the various grades of stainless steel.
