Anchor system for rotator cuff injury repair and using method thereof

A rotator cuff injury and anchoring technology is applied in the field of anchoring system for rotator cuff injury repair, which can solve the problem that the attachment parts of the tendon are delayed to grow together, it is not easy to stick to the humeral head, and the anti-pullout performance of the anchor is solved. Weakness and other problems, to achieve the effect of reducing the probability of re-operation, saving medical costs, and increasing difficulty

Problems solved by technology

[0008] The weaker the pull-out resistance of the anchor, the easier it is for the anchor to pull out from the humeral head, the weaker the force of the suture to press the tendon to the humeral head, and the less likely the attachment part of the tendon is to stick to the humeral head, thus delaying The attachment part of the tendon is reattached to the humeral head
Once the anchor is pulled out from the humeral head, it needs to be re-operated, which will delay the patient's recovery and increase medical costs

Embodiment 1

[0064] Such as Figure 8-10 As shown, an anchor system for repairing a rotator cuff injury includes an anchor 1 , a straight barrel 2 , a push rod 3 , and a suture 4 .

[0065] Anchor 1 is used for insertion into the humeral head. The outer surface of the anchor 1 is provided with an external thread, and the tail end of the anchor 1 is provided with a threading hole 101 , and the threading hole 101 is used for threading the suture 4 . The tail end of the anchor 1 is also provided with a square hole 102 (the square hole 102 is a quadrangular prism-shaped hole). After one end of the push rod 3 is inserted into the square hole 102, the push rod 3 is rotated, and the anchor 1 can follow the push rod 3. turn. Except adopting square hole 102, also can adopt triangular prism hole or pentagonal prism hole or hexagonal prism hole to replace, for example when adopting triangular prism hole, push rod 3 then adopts the triangular prism shape that matches with triangular prism hole. . ...

Embodiment 2

[0078] Such as Figure 15-17 As shown, an anchor system for repairing a rotator cuff injury includes an anchor 1 , a straight barrel 2 , a push rod 3 , and a suture 4 .

[0079] The straight barrel 2 is used to insert into the gap between the humeral head and the acromion. One end of the straight cylinder 2 is provided with a reversing portion, and the reversing portion adopts a position-limiting protrusion 6 , the position-limiting protrusion 6 is arranged in the inner cavity of the straight cylinder 2 , and the position-limiting protrusion 6 and the straight cylinder 2 are integrally formed.

[0080] Anchor 1 is used for insertion into the humeral head. The tail end of the anchor 1 is provided with a threading hole 101 , and the threading hole 101 is used for threading the suture 4 . The tail end of the anchor 1 is also provided with a square hole 102 (the square hole 102 is a quadrangular prism-shaped hole). After one end of the push rod 3 is inserted into the square hole...

Embodiment 3

[0091] Embodiment 3 is the same as Embodiment 2, except that, in the anchor system for rotator cuff repair in Embodiment 3, the threading hole 101 is provided at the tip of the anchor 1 .

[0092] When the threading hole 101 is set at the tip of the anchor 1, between step (2) and step (3) of Embodiment 2, the following operations need to be performed: while keeping the push rod 3 to push the anchor 1, outward Pull the suture 4, so that the anchor 1 rotates counterclockwise with the contact position of the anchor 1 and the push rod 3 as the center of rotation, so that the tip of the anchor 1 deflects toward the direction in which the straight cylinder 2 draws out the gap between the humeral head and the acromion, Such as Figure 24 shown.

[0093] Through the above process, it can be known that:

[0094] In this embodiment 3, on the basis of embodiment 2, by deflecting the tip of the anchor 1 toward the direction in which the straight tube 2 draws out the gap between the hume...

Abstract

The invention discloses an anchor system for rotator cuff injury repair and a using method thereof. The anchor system comprises an anchor, a suture line, a straight cylinder and a push rod; the anchorused for being inserted into the humerus head is provided with a threading hole and a square hole, the threading hole is used for threading the suture line, and the square hole is used for being matched with one end of the push rod; the push rod and the suture line are both arranged in a straight cylinder used for being inserted into the gap between the humerus head and the acromion, a reversingpart is arranged at one end of the straight cylinder, and when the push rod used for pushing the anchor pushes the anchor out of the reversing part, the direction of the anchor inserted into the humerus head deviates from the direction of the straight cylinder inserted into the gap between the humerus head and the acromion. The using method comprises the steps: enabling the end, away from the straight tube, of a bent tube to face the bone surface of the humerus head; enabling the tip end of the anchor to abut against the tendon, and piercing the tendon with the tip end of the anchor; screwingthe anchor into the humerus head; and finally, leaving the anchor and the suture line on the humerus head. The anti-pull-out performance of the anchor can be improved.

Description

technical field [0001] The invention relates to the technical field of rotator cuff injury repair, in particular to an anchor system for rotator cuff injury repair and a use method thereof. Background technique [0002] The rotator cuff is a group of tendon complexes wrapped around the humeral head, including the subscapularis tendon, supraspinatus tendon, infraspinatus tendon, and teres minor tendon. The rotator cuff plays an important role in maintaining shoulder joint stability and shoulder joint mobility. [0003] Rotator cuff injuries mostly refer to PASTA (partial articular surface tendon avulsion) injuries, and PASTA injuries are common on the supraspinatus tendon. E.g figure 1 As shown, the tendon attaches to the humeral head, and in PASTA injuries, as figure 2 As shown, it refers to the phenomenon that the tendon is separated from the humeral head at the attachment part. [0004] In this regard, it is necessary to reattach the attached part of the tendon to the ...
