The protrusion of the intervertebral disc is one of clinical common diseases, and the number of patients tends to rise year by year; the most common cause of the disease is that the nucleus pulposus, the annulus fibrosus, the cartilaginous plates and the like of each part of the intervertebral disc are subjected to different degrees of degenerative changes, and the annulus fibrosus of the intervertebral disc is broken and the nucleus pulposus protrudes under the action of external force factors, so that a series of clinical symptoms such as lumbago or lower limb radiation pain are generated; in the minimally invasive surgery of spinal surgery, a medical staff usually cuts and establishes a minimally invasive surgery channel (the diameter is 28mm, the depth is 50 mm) on the skin of a human body to reach a diseased intervertebral disc, then the medical staff cuts a tiny incision (about 5-10 mm) on the annulus fibrosus of the intervertebral disc, and then the medical staff sequentially passes through the minimally invasive channel and the annulus fibrosus through special minimally invasive surgery instruments to perform further surgery operations such as nuclectomy and the like, the residual annulus fibrosus after nuclectomy is conventionally not effectively sutured and closed by proper surgery machinery, and accordingly the postoperative intervertebral disc protrusion is recrudesced again.
In recent years, there are some special annular staplers for minimally invasive surgery on the market, but these staplers have more or less respective drawbacks, and are inconvenient or safe in clinical application, such as a commercially available stapler (CN 217244575U), the principle is that two separate sutures are fixed on two sides of an annular incision by an anchoring structure, and the two separate sutures are knotted by a knotting technique, so as to close the annular incision. The problem is that such deep tissue tying techniques based on two different sutures are very difficult, it is difficult to tighten the knot, and the knot is prone to slackening, or to forcefully tighten the knot, resulting in suture breakage or slippage of the anchoring structure. Or another suture device (CN 113827292 a), the principle is that two ends of the same suture thread are respectively passed through two sides of the annular incision by a puncture thread passing device, and the knots are tied by using a conventional knotting technique, so that the knotting technique based on two different suture threads is avoided, but the problem is that the puncture thread passing technique has complicated operation, especially the puncture angle depth is difficult to grasp, namely, the puncture angle is required to be respectively inclined from two sides of the incision to the central position of the incision, in a narrow space, the proper inclination angle is difficult to be set, and meanwhile, the thread ends are difficult to be smoothly, safely and simply led out from deep tissues after the puncture due to the problem of operation vision.
As shown in fig. 1, 2, 3, 4, 5, 6 and 7, an embodiment of the present invention provides an annular stapler including: the puncture outfit comprises a puncture outfit sleeve 10 and a single suture line 20 which is arranged in the puncture outfit sleeve 10 and can slide along the puncture outfit sleeve, wherein two free ends of the suture line 20 are positioned at one end of the puncture outfit sleeve 10 far away from a spike, and the two free ends are mutually wound to form a three-star knot 30;
wherein, two anchoring structures 40 are slidably arranged on the suture 20 at a certain distance, a push rod 50 which can be separated from each anchoring structure 40 is arranged on each anchoring structure 40, the push rod 50 extends along the length direction of the anchoring structure, and the push rod 50 can push the anchoring structure 40 to drive the suture 20 to move out of the puncture outfit sleeve 10.
In the present invention, the above-mentioned scheme is adopted, so that, during the use, the puncture device sleeve 10 is respectively punctured at two sides of the annular incision at any angle (without deliberately pursuing the puncture angle), after the push rod 50 pushes the anchoring structure 40, the push rod 50 is held by one hand, the suture 20 is pulled by one hand, the asymmetric design of the anchoring structure 40 and the rotatable design between the anchoring structure 40 and the push rod 50 thereof can easily change the anchoring structure 40 from the longitudinal direction to the transverse direction, and when the anchoring structure 40 and the push rod 50 thereof are turned at an angle of 90 °, the push rod 50 can be separated from the anchoring structure 40, after the push rod 50 is separated, the two anchoring structures 40 are respectively arranged at two sides of the annular incision, the three-star knots preset at two free ends are pushed downwards by using a conventional knot pusher, and the suture 20 can close the annular incision in combination with a subsequent series of conventional half knots. The knotting method realized on a single suture line is convenient to operate and firm in knotting, and after the annular incision is closed, the risk of secondary extraction of nucleus pulposus tissues from the annular incision can be reduced, so that the probability of recurrence of the protrusion of the intervertebral disc is reduced; by adopting the scheme, the problem of soft tissue suturing in a deep narrow space, namely difficult suturing and knotting technology of the deep tissue, can be solved; the problems that the traditional suturing device is difficult to grasp the depth of the puncture angle and difficult to lead out the thread head smoothly from the deep tissue conveniently and safely are overcome.
In order to make the anchoring structures 40 slidable on the sutures 20, two through-holes 41 are provided in front of each anchoring structure 40, and after the sutures 20 sequentially pass through the two through-holes 41, the sutures 20 can slide in the two through-holes 41, so that the anchoring structures 40 are slidably mounted on the sutures 20.

In order to further increase the stability of the suture, each anchoring structure 40 is configured as an asymmetric structure, and after the push rod 50 is held by one hand and the suture 20 is pulled by the other hand, each anchoring structure 40 automatically turns transversely, so as to further increase the contact area between the anchoring structure 40 and the intervertebral disc tissue, thereby further increasing the stability of the suture and reducing the withdrawal risk.
In order to make the push rods 50 and the anchoring structures 40 separable, a star structure 51 is arranged at the top end of each push rod 50, the anchoring structures 40 are provided with push rod fixing grooves 43 at positions corresponding to the push rods 50, the star structures 51 can rivet the push rod fixing grooves 43, and when the push rods 50 are longitudinally connected with the anchoring structures 40, the push rod fixing grooves 43 cannot be separated from the star structures 51; when the push rod 50 is perpendicular to the anchoring structure 40, the star structure 51 can be disengaged from the push rod fixing groove 43.
In the invention, the working principle and the operation principle of the fiber ring stitching instrument are as follows:
working principle: by means of a single suture thread 20 with two anchoring structures 40 arranged in the puncture outfit sleeve 10, the puncture outfit sleeve 10 punctures two sides of the annular incision at any angle (without deliberately pursuing the puncturing angle), the two anchoring structures 40 are arranged on two sides of the annular incision, the anchoring structures 40 are slidably arranged on the suture thread 20, thus the preset three-star knot on the suture thread 20 can be easily pushed to the annular incision and fastened by pulling two free ends of the suture thread, and finally the knot is locked by a series of conventional half knots, so that the annular incision is completely closed; moreover, to prevent withdrawal of the anchoring structure 40, barbs 42 are provided on the anchoring structure 40 and the anchoring structure 40 itself is provided in an asymmetric design so that the anchoring structure 40 automatically turns laterally after tightening the suture 20, further preventing withdrawal of the anchoring structure 40.
Principle of operation: inserting the puncture outfit sheath 10 into the depth of the intervertebral disc at one side of the annulotomy, pushing the anchoring structure 40 out of the puncture outfit sheath 10 into the intervertebral disc by using one push rod 50, pushing one push rod 50 by one hand, pulling the tail of the suture 20 by one hand, so that the anchoring structure 40 is changed from the longitudinal direction to the transverse direction in the intervertebral disc, and at the moment, the one push rod 50 can be smoothly separated from the push rod fixing groove 43; thus, one of the anchoring structures 40 is positioned, the other anchoring structure 40 is pushed to the spike of the puncture outfit sheath 10 by the other push rod 50, and the other anchoring structure 40 is implanted in the same manner;
the suture 20 passes through the annulus fibrosus from outside the body into the disc, passes through the two wire holes 41 of the anchoring structure 40, and then passes out of the disc to outside the body; crossing the annular incision, penetrating the annulus again from outside the body into the intervertebral disc, penetrating through the two wire through holes 41 of the anchoring structure 40, and then exiting from the intervertebral disc to outside the body; finally, the conventional knot pusher is used for locking the three star knots and the subsequent half knots, and the operation is convenient and quick.
