The invention is directed to a device for the coupling of surgical instruments and/or implants such as a drive shaft and a reamer head. The device comprises a longitudinal male connector, and a hollow coupling shank having a first bore extending therethrough for receiving the male connector. The lateral portion of the male connector includes a plurality of flat surfaces, and the first bore shank includes a plurality of wall surfaces corresponding to the flat surfaces, so that the male connector can be inserted into the first bore to form a connection which is resistant to twisting about the longitudinal axis. The male connector defines a second bore extending coaxially therethrough and includes at least one radial slot, and defining a radially elastic, compressible holding element extending from the distal end. The male connector includes at least one radially protruding latch finger; and the first bore includes at least one latch finger recess to engage the latch finger so that the male connector can be axially fixed with respect to the shank. The latch finger and recess comprise disengagement means which permit disengagement by applying a disengagement tensile force on the male connector in the proximal direction. |
