Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a wire anchor and a manufacturing method thereof.
Background
Lumbar disc herniation is one of the more common diseases, mainly because after various parts of lumbar disc, especially nucleus pulposus, are changed in different degrees of retrogressions, the annulus fibrosus of the intervertebral disc is broken under the action of force factors to form an annular gap, and nucleus pulposus tissues protrude to the rear or in the vertebral canal from the broken position, so that adjacent spinal nerve roots are stimulated or pressed, and a series of clinical symptoms such as lumbar pain, numbness of one or two lower limbs, pain and the like are caused. The traditional surgical treatment method is to resect the protruding nucleus pulposus and free annulus fibrosus tissue to relieve the compression of the nerve root. However, the biggest technical challenges presented by nuclectomy procedures are: after nuclectomy, the presence of a break/incision in the annulus fibrosus may serve as a passageway for the remaining nucleus pulposus to re-protrude. The recurrence rate after operation treatment is about 3-27% and the average recurrence rate is 8-12% after statistics. The main technology of the annulus repair is surgical direct suturing of the annulus. Wire anchors are a common medical device in performing wound closure.
In the process of performing operations on the spine position, for example, when treating diseases such as lumbar disc herniation, medical staff needs to make a certain-size annular incision on the annulus fibrosus at the spine position, and then dig out the nucleus pulposus protruding in the annulus fibrosus through the annular incision so as to achieve the purpose of treating lumbar disc herniation. And after the convex portion of the nucleus pulposus is dug out, the medical staff needs to suture the incision on the annulus fibrosus. A gun type fiber ring suture device recorded in the prior art CN107822680B disposable fiber ring suture device so as to realize suture suturing of deep incision or minimally invasive operation incision; the inventors have found that such a fibrous ring stapler includes a stapler housing, a stapling assembly, and a transmission assembly; the transmission assembly is positioned in the stitching instrument shell, and is connected with the stitching assembly and controls the stitching assembly to perform stitching operation. The suture device realizes suture in a small space by utilizing the instrument structure, has complex design principle and instrument structure, and can lead to the failure of the whole product if any part or component fails, and has lower structural stability, higher manufacturing cost and difficult popularization. The tail end of the fiber ring stitching instrument in the prior art CN215228017U, namely a strip line anchor nail, is of a T-shaped anchor bolt structure, the tail part of the T-shaped anchor bolt is connected with a tail wire, and the T-shaped anchor bolt is connected with the tail wire by using biological glue for shaping treatment. And a plurality of suture ropes which are arranged in parallel are shaped by using biological glue to prepare the anchor, and are connected with the suture lines and are fixed by the biological glue in an adhesive manner to form the anchor with the thread. The prior art CN113598853B 'tool for manufacturing the belt line anchor and method for manufacturing the belt line anchor' also discloses the tool for manufacturing the belt line anchor by combining with the biological glue for bonding and fixing and the manufacturing method thereof. However, at present, the biological glue has higher biological safety risk for long-term implantation of the biological glue into human bodies, and no research is carried out for a short time, so that the biological glue can be proved to be safe for long-term implantation of the biological glue into human bodies. If a cast implant is used, it is a hard implant, and has cut annulus tissue and a pronounced foreign body sensation.
Therefore, it is desirable to provide a suture anchor and a method of making the same that solves the technical problem of the implant containing bio-glue, while using a flexible anchor does not cut back soft tissue and create foreign body sensation.
