Technical Data

No-Play Ratcheting Screwdrivers with Molded Silicone Handles

First to develop and patent the No-Play technology, today, all Gauthier Biomedical ratcheting screwdrivers are available with our proprietary, all stainless, No-Play ratcheting mechanism. This original and exclusive design limits axial and side-to-side "play" or "wobble" between the shaft and handle. The result is a smooth, precise and strong ratchet feel. Gauthier Biomedical’s No-Play Ratcheting handles are protected by US Patent numbers 6,817,458; 6,948,605; 7,014,023; 7,156,216; 7,413,065; and other patents pending.


    • Ratcheting body is machined into the handle – it is NOT glued into the handle
    • No adhesives or lubricants
    • No axial movement between handle
    • No side-to-side movement
    • All stainless steel construction
    • Fully autoclavable
    • Re-useable
    • 36 clicks/per revolution 10 degrees of motion to actuate the mechanism
    • Very low back torque, for small torque applications
    • Allows for very large cannulations
    • High torque capacity >250 in-lbs of torque can be applied to this design
    • Dual Bearing Design provides a very smooth and consistent feel
    • Can be configured into any of our handles or custom instruments


Gauthier Biomedical offers custom silicone molded handles in virtually any color under the sun. Utilizing the Pantone Matching System (PMS), we can provide you with the handle color you need. Use the color chart below to select one of our many standard colors. Identify your handle color by indicating the color code (letter) following the handle part number(eg. G100552_A, where "_A" identifies Blue PMS 285). If you don't see the color you're looking for please contact us and we'll work with you to get you exactly what you need.

These colour chips are screen values only and intended for general reference only. Printed colours may vary. To ensure accurate color communication please reference an up-to-date Pantone formula guide.

Instrument Care

Maintenance Guide

Use of instruments other than their intended purpose, such as cutting, holding, clamping, retracting, torqueing, etc., should be avoided to prevent undue stress or strain which could break or damage the instruments. All instruments are shipped in a NON‐STERILE condition and must be cleaned, lubricated, and autoclaved prior to use.


Clean instruments as quickly as possible after use. Do not allow blood and debris to dry on the instruments. If cleaning must be delayed, place groups of instruments in a covered container with appropriate detergent or enzymatic solution to delay drying. After surgery, open all box locks and disassemble instruments with removable parts. This will limit blood drying on instruments that may cause them to corrode. Do not use abrasive pads or cleansers, which will scratch the surface allowing dirt and water deposits to collect. Abrasive cleaning will remove the protective passive layer. Do not use high concentrations of chlorine bleach or disinfect stainless steel instruments, as pitting will occur. Sort instruments by similar metal for subsequent processing so that electrolytic deposition (galvanic corrosion) due to contact between dissimilar metals will not occur. Ultrasonic cleaners are very effective when used with hot water per manufacturer’s recommended temperature and specially formulated detergents. It is recommended that all visible debris and blood be removed from the instrument prior to ultrasonic cleaning. Sort instruments by similar metal for subsequent processing so that electrolytic (galvanic corrosion) due to contact between dissimilar metals will not occur. It is not recommended to clean plated instruments in an ultrasonic cleaner since the ultrasonic vibration and the presence of other sharp instruments may crack or rupture the plating.

Corrosion Resistance

Stainless steel surgical instruments are made of corrosion resistant high‐grade specialty steels. The key word here is “resistant” and we are emphasizing this feature to make the user aware that corrosion resistant does not mean corrosion proof. One of the special characteristics of these steels is that they form a passive oxide layer on the surface, which protects them against corrosion. Every effort has been made to make your instruments as corrosion resistant as possible. It is imperative that you, as the user, must do your part by treating them properly. If this is not done the steel can rust or stain which can reduce the life of the instrument or render it useless. One further note is that not all stainless steel has the same corrosion resistance. When strength and hardness requirements are important factors for instrument function, corrosion resistance is generally lower.


To protect instruments from staining and rusting during sterilization and storage, they should be lubricated with a water‐soluble, preserved lubricant after each cleaning. Since effective ultrasonic cleaning removes all lubricant, relubrication is important. The lubricant should contain a chemical preservative to prevent bacterial growth in the lubricant bath. The bath solution should be made with demineralized water. A lubricant containing a rust inhibitor helps prevent electrolytic corrosion of points and edges. Immediately after cleaning, instrument should be immersed for 30 seconds and allowed to drain off, not wiped off. A lubricant film will remain through the sterilization to protect them during storage.


Staining and spotting may result if residual chemicals are not completely rinsed from instruments that are subjected to steam sterilization. Following proper drying cycles, and the equipment manufacturer’s recommendations are vital to preventing the formation of excess moisture and the resultant water spotting.

These guidelines were written to give a general understanding of the nature and concerns associated with the care and cleaning of surgical instruments. Attention has been paid to chemical and corrosion contacts that may inadvertently degrade, corrode, or otherwise shorten the expected life of hand held surgical instruments. These guidelines are not intended to be a complete or precise document with regard to all possible chemical contacts or reactions that may occur in a particular situation.
