System for Connecting a Connecting Device, in Particular a Distractor, to a Bone

System according to any of the preceding claims, wherein the opening comprises, seen along the longitudinal axis of the opening, a first section having a first diameter and a second section having a second diameter corresponding to the outer diameter of the guiding tube, wherein the first diameter is larger than the second diameter.

System according to any of the preceding claims, wherein the opening of the connection device and the locking device are provided with cooperating connecting means for interconnecting the locking device and the connection device.

System according to any of the preceding claims, further comprising a guiding element for guiding the guiding tube, wherein the guiding element is arranged to be received in the opening of the connection device, wherein the guiding element has an outer diameter corresponding to the diameter of the opening and wherein the guiding element has an inner diameter corresponding to the outer diameter of the guiding tube, wherein the guiding element and the guiding tube are removable from the combination of the bone pin and the connection device.

System according to any of the preceding claims, further comprising a second locking device, wherein the connection device comprises a second opening for receiving a second bone pin, wherein the longitudinal axes of the first and the second openings are substantially parallel and wherein the second locking device is arranged to lock the second bone pin after removal of a guiding tube from the second opening.

External orthopaedic device arranged to be connected between a first bone part and a second bone part, wherein the orthopaedic device comprises a first connection device as defined in any of the preceding claims and a second connection device, preferably as defined in any of the of the preceding claims.

External distractor arranged to gradually enlarge the distance between a first bone part and a second bone part, wherein the distractor comprises a first connection device as defined in any of the preceding claims and a second connection device, preferably as defined in any of the of the preceding claims, wherein the first connection device is arranged to be connected to the first bone part with at least one first bone pin and wherein the second connection device is arranged to be connected to the second bone part with at least one second bone pin, wherein the first and second connection devices are interconnected via at least a distraction device, the distraction device having an adjustable length for adjusting the distance between the first and the second connection devices along an adjustment axis.

External distractor according to any of the preceding claims, wherein at least one of the connection devices is arranged to be connected to the bone part with two substantially parallel bone pins.
