Abstract:
1. A clamping pin intended to be inserted into and held in an opening of a medical device, wherein the clamping pin comprising: a screw having a longitudinal axis; a clamping section being complementary to an opening in a medical device; a first clamping element having an inclined surface that is inclined to the longitudinal axis and a first part of the clamping section, and a second clamping element having an inclined surface that is inclined to the longitudinal axis and a second part of the clamping section, the second clamping element having an internal threaded section; wherein the inclined surface of the first clamping element is in contact with the inclined surface of the second clamping element; wherein the screw extends only partly through an inner bore of the second clamping element and entirely through an inner bore of the first clamping element and wherein the screw engages the threaded section of the second clamping element inner bore such that the axial distance between the clamping elements and the diameter of the clamping section that can come in contact with a surface of the opening in the medical device will be changed upon actuation of the screw, the second clamping element inner bore receiving a connection module for connecting the clamping pin to a further element; wherein the clamping pin comprises a compression spring with several windings, which is arranged such that it provides an axial force onto the first clamping element such that said first clamping element is pushed away from the second clamping element such that the diameter (D) of the clamping section decreases, wherein movement of the first clamping element towards the second clamping element against the spring force causes an increased diameter (D) wherein the increased diameter (D) comes into contact with said surface of the opening in order to provide a spring-biased connection between the medical device and the clamping pin and wherein the diameter (D) can be increased further by actuating said screw in order to provide a clamping force.
