Description

tissue closure device

The present invention relates to a tissue closure device for suturing a torn rotator cuff.

In general, the rotator cuff refers to the four muscles that cover the shoulder joint: the supraspinatus, the infraspinatus, the subscapularis, and the teres minor. These four muscles are responsible for maintaining the rotational movement and stability of the shoulder joint. However, a disease in which one or more of these four muscles rupture and cause pain in the arm and shoulder is a rotator cuff tear. Injuries to the rotator cuff are the most common cause of chronic pain in the shoulder joint.

Before rotator cuff suture surgery, the rotator cuff tear is diagnosed with a magnetic resonance imaging (MRI) device, and the ruptured shape, location, and size are diagnosed and then the tear operation is performed.

Specifically, in the rotator cuff suture operation, the skin to be operated is incised, a hole is drilled into the bone, an anchor is inserted, and a ruptured muscle, tendon or ligament is threaded and coupled to the bone using a suture connected to the anchor. The anchor drills a hole for threading the suture, inserts the suture into the anchor, and sutures the muscle, tendon or ligament through this suture. Or allow the ligaments to be anchored to the bone.

However, since the conventional tissue suture device does not provide a separate suture tension device, there is a problem in that the tension of the suture connected to the anchor is not constantly maintained in the process of implanting the anchor.

Inserting the suture 70 into the insertion space 23c of the capture unit 23, and then pulling both ends of the suture 70 with the capture unit 23 as the center, the fitting groove 41 of the second handle 40 insert and fasten

The suture 70 positioned in the insertion space 23c of the capture unit 23 is positioned between the ring 90 and the separation preventing thread T. It is possible to completely prevent the suture 70 from being separated from the insertion space 23c of the capture part 23 in the process of moving the capture part 23 to the implantation site 80 by the separation preventing thread T. .

Referring to FIG. 28 , before implantation of the anchor 60 , the suture 70 may be supported by the capture unit 23 of the second shaft 20 .

As shown in FIG. 29 , the departure preventing screw T removes the anchor 60 immediately before implantation in the implantation site 80 , and then proceeds with the implantation of the anchor 60 so that the anchor 60 is screwed to the implantation site 80 . .
