Description
Technical Field
The invention relates to the technical field of rotator cuff injury repair, in particular to an anchor system for rotator cuff injury repair.
Background
The rotator cuff is a group of tendon complex surrounding the humeral head, including the subscapularis tendon, supraspinatus tendon, infraspinatus tendon and teres minor tendon, and plays an important role in maintaining the stability of the shoulder joint and the movement of the shoulder joint.
Most rotator cuff injuries refer to PASTA (torn tendon on part of the articular surface) injuries, which are commonly found on the supraspinatus tendon. For example, as shown in fig. 1, the tendon is attached to the humeral head, and in the PASTA injury, as shown in fig. 2, it means that the tendon is separated from the humeral head at the attached portion.
In this regard, it is necessary to attach the attachment portion of the tendon against the humeral head again to perform the repair, and a suture anchor (i.e., an anchor with a suture) is provided at a position on the humeral head where the tendon is originally attached to lay a foundation for the suture bridge technique, which can press the tendon against the humeral head using the suture to attach the attachment portion of the tendon against the humeral head again, so that the attachment portion of the tendon is grown together with the humeral head again.
In setting a suture anchor, a tool to the anchor system is required. As shown in fig. 3, the conventional anchor system includes an anchor 1, a straight tube 2, a push rod 3, and a suture 4, wherein a tail portion of the anchor 1 is provided with a threading hole 101 and a square hole 102, the suture 4 passes through the threading hole 101, one end of the push rod 3 is inserted into the square hole 102, and both the push rod 3 and the suture 4 are accommodated in an inner cavity of the straight tube 2.
The method of use of the anchor system is as follows: (1) since the shoulder is shielded above the humeral head to which the tendon is attached, it is required for the surgeon to insert the straight cylinder 2 obliquely into the gap between the shoulder and the humeral head, as shown in fig. 4; (2) after the straight cylinder 2 is obliquely inserted into the shoulder and the humeral head, the sharp property of the tip of the anchor 1 is utilized to puncture the tendon, and the straight cylinder 2 and the push rod 3 are continuously fed to the humeral head, as shown in fig. 5; (3) the physician screws the push rod 3 to screw the anchor 1 into the humeral head, as shown in fig. 6; (4) the handle is withdrawn and only the anchor 1 with the suture 4 threaded therethrough remains on the humeral head as shown in fig. 7.
As shown in fig. 7, since the gap between the humeral head and the acromion is narrow and the direction of insertion of the anchor into the humeral head is the same as the direction of insertion of the stem into the gap between the humeral head and the acromion, the direction L1 of pulling the anchor (the direction of pulling the anchor means the direction of pulling the anchor with the suture and also the direction of insertion of the stem into the gap between the humeral head and the acromion) and the direction L2 of insertion of the anchor into the humeral head are almost parallel, thereby decreasing the pullout resistance of the anchor.
The weaker the pullout resistance of the anchor, the easier the anchor is to pull out from the humeral head, the weaker the force with which the suture presses the tendon against the humeral head, the less likely the attachment portion of the tendon will rest against the humeral head, thereby delaying the attachment portion of the tendon from growing back with the humeral head. Once the anchor is extracted from the humeral head, the operation needs to be re-performed, which delays patient recovery and increases medical costs.
Therefore, how to improve the pullout resistance of the anchor bolt is a technical problem that needs to be solved by those skilled in the art.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Example 1:
as shown in fig. 8-10, an anchoring system for repairing rotator cuff injury comprises an anchoring nail 1, a straight barrel 2, a push rod 3 and a suture 4.
The straight barrel 2 is used for insertion into the gap between the humeral head and the acromion. The one end of straight section of thick bamboo 2 is equipped with the switching-over portion, and the switching-over portion adopts curved section of thick bamboo 5, and curved section of thick bamboo 5 and straight section of thick bamboo 2 are integrated into one piece, and the inner chamber of curved section of thick bamboo 5 communicates with the inner chamber of straight section of thick bamboo 2, and the axis of curved section of thick bamboo 5 is 160 and adds sour 165 for the contained angle b of the axis of straight section of thick bamboo 2.
The push rod 3 and the suture 4 sequentially pass through the inner cavity of the straight barrel 2 and the inner cavity of the bent barrel 5. The push rod 3 is an elastic rod. The push rod 3 is used for pushing the anchor 1 from the inner cavity of the straight barrel 2 to the inner cavity of the bent barrel 5, and the push rod 3 is continuously used for pushing the anchor 1, so that the anchor 1 can be pushed out from the inner cavity of the bent barrel 5. Specifically, the push rod 3 is a titanium alloy rod having high strength, high toughness, and remarkable spring back. In addition, the push rod 3 of the background art can be directly used, because the push rod 3 is in the shape of an elongated rod, and the elongated rod has good toughness and resilience. When the anchor 1 is pushed along the straight tube 2 or the curved tube 5 by using the push rod 3, the push rod 3 has elasticity, so that when one end of the push rod 3 close to the anchor 1 is inserted into the curved tube 5, the push rod 3 can be bent along with the turning of the curved tube 5, and when the push rod 3 is withdrawn from the curved tube 5, the push rod 3 is restored. Also, because the push rod 3 has elasticity, when the push rod 3 pushes the anchor 1 out of the curved tube 5 and one end of the push rod 3 close to the anchor 1 is still inserted into the inner cavity of the curved tube 5, the push rod 3 is screwed, and a part of the push rod 3 inserted into the curved tube 5 is also rotated, so that the anchor 1 can be driven to rotate together.
A method of using an anchor system for rotator cuff injury repair comprising the steps of:
(1) the straight cylinder 2 is inserted into the gap between the humeral head and the acromion, and the straight cylinder 2 is rotated to enable the curved cylinder 5 to face the bone surface of the humeral head at one end far away from the straight cylinder 2.
(2) The push rod 3 is used to push the anchor 1 out of the curved tube 5 so that the tip of the anchor 1 abuts on the tendon, as shown in fig. 11, and the tip of the anchor 1 is used to pierce the tendon, as shown in fig. 12. Since the curved barrel 5 is directed toward the bone surface of the humeral head at the end away from the straight barrel 2 in step (1), when the anchor 1 is pushed out from the curved barrel 5 by the push rod 3, the direction of the tip of the anchor 1 can be made to coincide with the direction of the curved barrel 5, both being directed toward the bone surface of the humeral head, so that the tip of the anchor 1 can be made to abut against the tendon, and the direction of the tip of the anchor 1 is deviated from the direction in which the straight barrel 2 is inserted into the gap between the humeral head and the acromion.
(3) The push rod 3 is screwed so that the anchor 1 is screwed into the humeral head, as shown in fig. 13. Since the tip of the anchor 1 is oriented in the direction deviating from the direction in which the straight barrel 2 is inserted into the gap between the humeral head and the acromion in step (2), the anchor 1 can be screwed into the humeral head when the push rod 3 is screwed, and the direction in which the anchor 1 is screwed into the humeral head is also deviated from the direction in which the straight barrel 2 is inserted into the gap between the humeral head and the acromion.
(4) The straight barrel 2 and the push rod 3 are withdrawn leaving the anchor 1 and suture 4 on the humeral head as shown in fig. 14.
Through the above process, it can be known that:
in the case of a narrow gap between the humeral head and the acromion, since the anchor 1 can be pushed by the push rod 3 to move in the direction of the curved barrel 5, so that when the end of the curved barrel 5 away from the straight barrel 2 is directed toward the bone surface of the humeral head, the anchor 1 can be screwed into the humeral head in a direction deviating from the direction in which the straight barrel 2 is inserted into the gap between the humeral head and the acromion, so that the direction L2' in which the anchor 1 is inserted into the bone surface of the humeral head and the direction L1 in which the anchor 1 is pulled are not parallel but at an angle a. Therefore, compared with the background art in which the direction L1 of the drawn anchor 1 and the direction L2 of the anchor 1 inserted into the humeral head are almost parallel, the anchor system for repairing rotator cuff injuries of the present embodiment 1 improves the pullout resistance of the anchor 1.
After the anti-extraction performance of the anchor 1 is improved, the difficulty of extracting the anchor 1 from the humeral head can be increased, the force of pressing the tendon onto the humeral head by the suture 4 is increased, the attachment part of the tendon can be tightly attached to the humeral head, and the attachment part of the tendon is promoted to grow together with the humeral head again. The risk that the anchor 1 is pulled out from the humerus head is reduced, the success rate of the operation is improved, the probability of performing the operation again is reduced, the recovery of a patient is prevented from being delayed, and the medical cost is saved.
Further, since the anchor system for repairing rotator cuff injury of the present embodiment 1 can weaken the influence of the shoulder point on the direction of insertion of the anchor 1 into the humeral head, that is, in the case where the gap between the humeral head and the shoulder point is narrow, the anchor 1 can be screwed into the humeral head in a direction deviating from the direction in which the stem 2 is inserted into the gap between the humeral head and the shoulder point, the anchor system for repairing rotator cuff injury of the present embodiment 1 is particularly suitable for the case where the supraspinatus tendon is injured by PASTA.
Example 2:
as shown in fig. 15-17, an anchor system for repairing rotator cuff injury comprises an anchor 1, a straight barrel 2, a push rod 3 and a suture 4.
The straight barrel 2 is used for insertion into the gap between the humeral head and the acromion. One end of the straight cylinder 2 is provided with a reversing part, the reversing part adopts a limiting bulge 6, the limiting bulge 6 is arranged in the inner cavity of the straight cylinder 2, and the limiting bulge 6 and the straight cylinder 2 are integrally formed.
The push rod 3 and the suture 4 are arranged in the inner cavity of the straight barrel 2. The push rod 3 is used for pushing the anchor 1 out of the inner cavity of the straight barrel 2, when the push rod 3 pushes the anchor 1 to one end of the straight barrel 2 provided with the limiting protrusion 6, the limiting protrusion 6 can slide into the limiting groove 103 of the anchor 1, the push rod 3 is continuously pushed, and the anchor 1 rotates around the limiting protrusion 6 because the limiting protrusion 6 is inserted into the limiting groove 103, so that the orientation of the tip of the anchor 1 is changed.
A method of using an anchor system for rotator cuff injury repair comprising the steps of:
(1) as shown in fig. 18, the straight barrel 2 is inserted into the gap between the humeral head and the acromion; pushing the anchor 1 by the push rod 3 until the limit projection 6 slides into the limit groove 103 of the anchor 1, as shown in fig. 19; the pushing rod 3 is further pushed to rotate the anchor 1 around the limit protrusion 6 until the tip of the anchor 1 abuts on the tendon, as shown in fig. 20, and at this time, the tip of the anchor 1 is oriented in a direction deviating from the direction in which the straight tube 2 is inserted into the gap between the humeral head and the acromion.
(2) Tapping the push rod 3 with a hammer causes the push rod 3 to push the anchor 1, allowing the anchor 1 to pierce the tendon and drive into the humeral head in a direction offset from the insertion of the straight barrel 2 into the gap between the humeral head and the acromion, as shown in fig. 21-22.
(3) The shaft 2 and the push rod 3 are withdrawn, leaving the anchor 1 and suture 4 on the humeral head, as shown in fig. 23.
Through the above process, it can be known that:
in the case of a narrow gap between the humeral head and the acromion, because of the arrangement of the position-limiting protrusion 6 and the arrangement of the position-limiting groove 103 on the anchor 1, when the push rod 3 is used to push the anchor 1, the anchor 1 can be rotated around the position-limiting protrusion 6, so that the anchor 1 can be driven into the humeral head in a direction deviating from the direction in which the straight tube 2 is inserted into the gap between the humeral head and the acromion, so that the direction L2' in which the anchor 1 is inserted into the humeral head and the direction L1 in which the anchor 1 is pulled are not parallel but have an included angle a. Therefore, compared with the background art in which the direction L1 of the anchor 1 is drawn and the direction L2 of the anchor 1 inserted into the humeral head are almost parallel, the anchor system for repairing rotator cuff injuries of the present embodiment improves the pullout resistance of the anchor 1.
After the anti-extraction performance of the anchor 1 is improved, the difficulty of extracting the anchor 1 from the humeral head can be increased, the force of pressing the tendon onto the humeral head by the suture 4 is increased, the attachment part of the tendon can be tightly attached to the humeral head, and the attachment part of the tendon is promoted to grow together with the humeral head again. The risk that the anchor 1 is pulled out from the humerus head is reduced, the success rate of the operation is improved, the probability of performing the operation again is reduced, the recovery of a patient is prevented from being delayed, and the medical cost is saved.
In addition, since the anchor system for repairing rotator cuff injury of embodiment 2 can also reduce the influence of the shoulder apex on the direction of insertion of the anchor 1 into the humeral head, that is, in the case where the gap between the humeral head and the shoulder apex is narrow, the anchor 1 can be screwed into the humeral head in a direction deviating from the direction in which the straight barrel 2 is inserted into the gap between the humeral head and the shoulder apex, the anchor system for repairing rotator cuff injury of embodiment 2 is also suitable for the case where the supraspinatus tendon is injured by PASTA.
Example 3:
the present embodiment 3 is the same as the embodiment 2, except that in the anchor system for repairing rotator cuff injury of the present embodiment 3, the threading hole 101 is provided at the tip of the anchor 1.
When the threading hole 101 is provided at the tip end of the anchor 1, the following operations are also required between step (2) and step (3) of embodiment 2: while keeping the push rod 3 pushing the anchor 1, the suture 4 is pulled outward, the anchor 1 is rotated counterclockwise with the contact position of the anchor 1 and the push rod 3 as a center of gyration, thereby deflecting the tip of the anchor 1 toward the direction in which the straight barrel 2 withdraws the gap between the humeral head and the acromion, as shown in fig. 24.
Through the above process, it can be known that:
in this embodiment 3, based on 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 humeral head and the shoulder, the included angle a between the direction L2' in which the anchor 1 is inserted into the bone surface of the humeral head and the drawing direction L1 of the anchor 1 can be further reduced, so that the effect of fixing the anchor 1 to the humeral head is further improved, and the pullout resistance of the anchor 1 is further improved. Further promoting the attachment part of the tendon to grow together with the humeral head again, further improving the success rate of the operation and saving the medical cost.
