Abstract: A spindle drive tool for adjusting a position of a head of a spindle relative to a piston of an electro-mechanical automatic lubrication system in which the spindle and piston are connected by complementary screw threads includes a mounting portion and a coupling portion connected to the mounting portion. The mounting portion includes a bearing surface having a spindle head inlet at a first end, a first cavity and a second cavity. The spindle head inlet opens into the first cavity, the first cavity has a cross section configured to couple with the spindle head such that the spindle head cannot rotate relative to the mounting portion while in the first cavity, and the second cavity is coaxially with the first cavity and has a larger cross section than the first cavity such that the spindle head can rotate freely in the second cavity.

Abstract: The present invention relates to a coupling device for a medical instrument, such as an endoscope, comprising a base part and two cooperating engaging elements connected to the base part, wherein the cooperating engaging elements being movable between a clamping position and a receiving position, wherein each of the cooperating engaging elements being linearly translationally movable between the clamping position and the receiving position, and wherein the translations of the cooperating engaging elements are located on a coinciding line. The present invention further relates to a method for coupling the device according to the present invention with a medical instrument and use of the device according to the present invention, as well as to a kit-of-parts and an insert for use in the device according to the present invention.
