Abstract
An instrument for holding a surgical tool or bone implant includes a handle with a bearing surface formed in one end for engaging the surgical tool. An elastically deformable plate is mounted on the handle body the plate having a catch element formed on a leading end thereof adapted to engage a coupling element formed on the surgical tool. The elastically deformable plate includes a cam follower formed in a recess thereon and includes a deformable spring section intermediate the can elements and the plate end with the catch element. An elongated pivotable loading member is rotatably mounted on the handle body. The loading member includes a cam surface for engaging the cam follower surface on the deformable plate. The cam surface on the loading member is shaped to elastically deform the elastically deformable plate section in a direction away from the plate catch element to thereby load and maintain a connecting force between the plate and the surgical tool or bone implant.
