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, 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 at least partly through the second clamping element and at least partly through the first clamping element and wherein the screw engages in one of the clamping elements 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, wherein the clamping pin further comprises a spring, which is arranged such that it provides an axial force onto one of the clamping elements such that said clamping element is pushed against the other clamping element such that the diameter (D) of the clamping section increases, 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, and wherein the at least one of the clamping elements comprises an element protruding over an outer circumferential surface thereof or into the circumferential surface, wherein said element can be used to move said clamping element against or away from the other clamping element.
