Continuing with our theme of surgical handles, we know the fit matters! That means there should be no gap between the back end of the blade and the front end of the surgical handle where they come together.

But do you know what handle you need for your blade? Does the terminology #3 fitment or #4 fitment mean anything, or does it sound like a foreign language?

Let us help clear up any confusion!

The fitment refers to the die-cut opening in the blade and the corresponding attachment portion of the surgical handle.  All of the blades and handles in our portfolio are manufactured according to the international specs, which means they will fit correctly together every time.

Some blades and surgical handles in the market today have been designed specifically for use together and are not compatible with any other brands.

Not here at Cincinnati Surgical!  Our blades,  even including our special safety KLEEN Blade Management System, are designed to work with both conventional #3 and #4 fitment surgical handles.  This means our blades fit on most conventional handles available in the market – as long as they are manufactured to the correct fitment standards and have not been worn down or damaged.

In addition to the conventional handles listed above, we have more handle option available.  The grip portion of the handle may be thicker or longer.  No matter what the handle looks like the fitment is still consistent with the measurements of # 3 and #4 fitment blades.
