As shown in Fig. 5, Fig. 6, Fig. 8 and Fig. 9, thefirst suturing assembly 20 comprises the firsthollow pipe 21, thefirst sewing needle 22,seal wire 23 and spool 24.The firsthollow pipe 21 is fixed in left accommodatinghousing 61, for example, be bonding.Thefirst sewing needle 22 is fixed in the firsthollow pipe 21, for example, be bonding, and the part of exposing outside left accommodatinghousing 61 of thefirst sewing needle 22 is bending.Seal wire 23 be can deformation using flexible wire, bend the sweep of putting into thefirst sewing needle 22 after V-shaped, the most advanced and sophisticated opening towards the first sewing needle 22.Spool 24 is fixed on the outside of the firsthollow pipe 21, compriseslong spool 241 and short-term pipe 242.As shown in Figure 2 and Figure 9,stitching thread 70 is made a call to a toe-in 71 and is enteredlong spool 241 again after the interior doubling of short-term pipe 242, is wrapped on thebobbin 14 onback casing 12 from the lower end oflong spool 241 is left.Utilizelong spool 241 and short-term pipe 242 to placestitching thread 70, make thatstitching thread 70 is well-regulated arranges, can avoidstitching thread 70 knottings, disorderly around.

As shown in Figure 2, Figure 5 and Figure 6, thefirst transmission component 40 comprisesejector sleeve 41 andpipe handle 42 and trigger 43.Ejector sleeve 41 movably stretches in thefirst sewing needle 22, and one end ofpipe handle 42 is fixed in lower end.As shown in Figure 2, the top oftrigger 43 is stretched in accommodation space 13, and can be around rotatingshaft 121 pivotables of being located on back casing 12.Theupper end 431 oftrigger 43, one end of stretching in accommodation space 13 is hinged with the other end of pipe handle 42.Therefore,, when user cocking 43,ejector sleeve 41 ejectsseal wire 23 under the promotion oftrigger 43 in thefirst sewing needle 22.

As shown in Fig. 5, Fig. 6 and Fig. 8, thesecond suturing assembly 30 comprises the secondhollow pipe 31 and the second sewing needle 32.The secondhollow pipe 31 is fixed in right accommodatinghousing 62, for example, be bonding.Thesecond sewing needle 32 is movably positioned at the secondhollow pipe 31, and its upper end haspin hole 321.

As shown in Figure 1, Figure 2, shown in Fig. 5, Fig. 6 and Fig. 7, thesecond transmission component 50 comprises pitch wheel 51 andtooth bar 52 and fastens and be exposed to the adjustment knob 53 of procapsid 11 with gear 51.Tooth bar 52 is fixed in the lower end of thesecond sewing needle 32, for example, be bonding, by gear 51 band carry-overbars 52, move, by thesecond sewing needle 32 from the interior release of the secondhollow pipe 31 or withdrawal.

Below, the suture that illustrates disposable use fibrous ring stiching instrument is installed and sew application.

First, carry out suture installation, as shown in Figure 9 and Figure 10, one end ofstitching thread 70 is fixed onseal wire 23, put into the sweep of thefirst sewing needle 22 afterseal wire 23 bending is V-shaped, the tip of V-arrangement seal wire 23 is towards the opening of the first sewing needle 22.Then place as shown in Figure 9stitching thread 70, the other end ofstitching thread 70 is accomplished fluently to toe-in 71 around the periphery of the secondhollow pipe 31 after the interior doubling of short-term pipe 242, then enter long spool 241.As shown in figure 11, the sweep of thefirst sewing needle 22 is thrust to a side of otch C.

Then, as shown in figure 12, clockwise rotate and adjust knob 53, band carry-overbar 52 advances, and thesecond sewing needle 32 is stretched out, and from the opposite side of otch C, thrusts.Then, as shown in figure 13, cocking 43, upper pushingtow pipe 41, and then promote theseal wire 23 onejector sleeve 41, the tip portion ofseal wire 23 is entered in thepin hole 321 of the second sewing needle 32.Then, as shown in figure 14, rotate counterclockwise and adjust knob 53, band carry-overbar 52 retreats, and thesecond sewing needle 32 is regained, and then theseal wire 23 entering inpin hole 321 is brought in the secondhollow pipe 31 via toe-in 71, now,stitching thread 70 enters opposite side from a side of otch C.Finally, as shown in figure 15, extract stiching instrument, toe-in 71 departs from from the secondhollow pipe 31, then can utilize tension toe-ins such as pushing away line device, completes once and sews up.After this, utilize identical method, carry out stitching subsequently, thereby whole otch C is sewed up.

In sum, this disposable use fibrous ring stiching instrument coordinates by the first suturing assembly and the second suturing assembly, thereby can complete the stitching to fibrous ring at gallery, make fibrous ring keep integrity, avoid due to the breach of fibrous ring, causing the recurrence of intervertebral disk hernia in the future, and, of the present utility model simple in structure, easy and safe to operate.

In addition, between various embodiment of the present utility model, also can carry out combination in any, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
