SYSTEMS AND METHODS FOR MINIMALLY INVASIVE SURGICAL PROCEDURES Russian patent published in 2014 - IPC A61B17/88 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. An anchor extension piece comprises an elongated body, the first pair of coupling elements, the second pair of coupling elements, and a locking mechanism. The elongated body extends between a proximal end portion and a distal end portion. The first pair of coupling elements is pivotally connected to the above distal end portion, wherein the above first pair of coupling elements is movable between the first configuration for receiving and releasing the first portion of a bone anchor and the second configuration for coupling with the above first portion of the above bone anchor. The second pair of coupling elements is pivotally connected to the above elongated body by the side of the above distal end portion and opposed to the above first pair of coupling elements, wherein the above second pair of coupling elements moves between the first configuration for receiving and releasing the second portion of the above bone anchor and the second configuration for coupling with the above second portion of the above bone anchor. The locking mechanism displaces axially in relation to the above elongated body, wherein the above locking mechanism is configured to lock the above first and second pairs of coupling elements in the above second configuration.

EFFECT: invention reduces the time of the recovery considerably, and reduces postoperative pain by minimal, if necessary, muscle dissection and local anaesthesia.
