ABSTRACT:
A handle for a medical instrument having a handle portion. The handle portion is fabricated from metal, preferably stainless steel, and is provided with at least one annular channel disposed completely around the handle portion. An elastomer material, preferably silicone rubber, is molded on the handle portion to completely cover the handle portion, where the elastomer material extends into and fills the channel. The elastomer material provides pressure within the channel when the medical instrument is heated during steam sterilization thereof so that the elastomer material defines a seal within the channel to prevent moisture from passing between the covered handle portion and the elastomer material. Additionally, the handle portion may be provided with holes extending therethrough which are filled with the elastomer material to additionally secure the elastomer material to the handle portion.
