Description
Technical Field
The application relates to the technical field of medical instruments, in particular to a rigid-flexible combined inner-outer row anchor and a double-row repairing and fixing method thereof.
Background
With the development of orthopaedics sports medicine, injury repair operations such as rotator cuff repair operations and hip labrum repair operations are becoming more and more popular. The rotator cuff is composed of supraspinatus, subspinatus, small circular muscle and tendinous tissue attached to the subscapula, and the rotator cuff plays a role in supporting, stabilizing and maintaining the normal pivot of the humerus head and the glenoid in the movement of the shoulder joint, and is also a weak point in the movement of the shoulder joint. Shoulder pain is caused by rotator cuff injury, which is mostly sustained dull pain, and rotator cuff tear repair surgery should be performed in time in order to ensure normal life and reduce pain of patients.
Current rotator cuff tear repair procedures include single row repair and double row repair. Only one row of anchors are fixed in the single-row repair, the fixed positions of the anchors are the outer sides of the cartilage edges, and the single-row repair is suitable for tearing smaller than 3 cm; double row repair is also called suture bridging technology, an inner row suture is used for connecting an outer row of anchors, the implantation position of the inner row of anchors is cartilage margin, the implantation position of the outer row of anchors is large nodule, and the inner row of suture and the outer row of suture are in bridging intersection shape to press the rotator cuff on the bone surface, so that the risk of pulling out the anchors is obviously reduced. The double-row repair is lower than the single-row repair crack formation by 42%, the strength is increased by 46%, and the maximum load is increased by 48%, so that the double-row repair healing rate is higher than that of the single-row repair, and the double-row repair has lower re-tearing rate than that of the single-row repair.
At present, the double-row repairing inner row anchors are made of titanium alloy anchors, PEEK anchors and other rigid anchors, and the recently developed full-suture anchors are fully flexible, however, the knot shape formed after the fully flexible anchors are clustered is uncertain, secondary deformation is easy to occur after stress, so that the full-suture anchors deformed in bone holes are easily pulled out of bone tunnels, and finally, the fixation failure results are caused, and the pullout resistance of the inner row anchors needs to be further improved. The outer anchor matched with the inner anchor is commonly used as a PEEK anchor, the suture after the inner fixation is fixed in the bone canal by means of the hard anchor, however, the long-term friction between the hard anchor and the bone canal after the hard anchor is implanted can enlarge the bone canal so as to lead the suture led out by the inner anchor to slide, the fixation failure is caused, the failure load is 200-400N, and therefore, the long-term effective fixation of the suture after the inner fixation can not be realized by only virtue of the extrusion force of PEEK and the suture in the bone canal, and the cyclic displacement is very large.

the total length of the hardened segment is 1% -99% of the total length of the flexible anchor I, and the number of the hardened segments is 2, because the traction wire I and the traction wire II need to pass through after encircling a plurality of circles in the flexible anchor I, if the number of the hardened segments is more, the self-threading of the suture after the inner row fixation in the flexible anchor I and the smoothness of sliding in the flexible anchor I can be affected.
