Abstract
A holder assembly for a surgical blade includes a handle assembly and a wrench for loosening/tightening the blade from/to the handle of the handle assembly. The handle assembly includes a collet having two longitudinal slits that enable the collet to secure the blade in a first and second direction to prevent slippage during operation. The collet fits in the handle and is secured by a retaining member that fits over the collet with the blade intact. The retaining member is loosened/tightened by a wrench that is part of the holder assembly. The wrench is configured to cover the blade completely when the wrench is placed in operation. Part of the cover is removable for cleaning by inserting the closed end of the wrench into the wrench body and pushing the cover's cap off.
