Specific embodiment.
For understanding better this utility model, by reference to the accompanying drawings, describe preferred embodiment in detail, should be appreciated that the present embodiment is for the present invention is described better, rather than to restriction of the present utility model.As Figure 1-5, this utility model is a kind of endoscopic suture device, comprise suturing nail 6, delivery conduit 15 and pusher 16, suturing nail 6 is made by memory material, and be fixed to and can be sewn the shape of organizing drawing to both sides, in the present embodiment, as shown in Figure 2, suturing nail is fixed to round, the shape of suturing nail typing can be sewn both sides to organize drawing as long as meet, suturing nail 6 memory material good by histocompatibility made as niti-shaped memorial alloy or polyurethane shape memory material with memory performance, suturing nail 6 is packed the body 5 of delivery conduit near being sewn within tissue holds before sewing up, after suturing nail is packed in body, as shown in Figure 3, delivery conduit body cross section 8 is flat, be also that tube cavity is flat, thereby the suturing nail of memory material is straightened and is positioned at body 5, pusher 16 is connected away from being sewn the tissue end with delivery conduit 15, and both connected modes are taked the joint docking, and as shown in Figure 6, delivery conduit 15 has catheter adapter 7, and propelling movement joint 10 docking of the pusher corresponding with its shape of cross section, pusher 16 is connected with and pushes seal wire 9 away from delivery conduit 15 ends, push the inner chamber of the other end of seal wire 9 through described delivery conduit 15, and near the suturing nail 6 in delivery conduit, suturing nail can push out in delivery conduit by pushed seal wire 9, when suturing nail is urged out delivery conduit, at first the tip 1 that its far-end is sharp enters and is sewn tissue, suturing nail tissue penetration part 2 also penetrates tissue then, due to Ultimum Ti or the superpower formative memory performance of polyurethane material, after entering tissue, suturing nail will become the round while finalizing the design very soon, until suturing nail restricted passage end 4 withstands tissue, final suturing nail becomes to meet the round after closing to insert in tissue, play the effect of fixing organization.
As shown in Figure 4, pusher 16 is singlehanded pusher, comprise pusher body 19, two front ring for fixings 11 and a propelling movement circle 12, described propelling movement circle 12 is positioned at pusher away from the delivery conduit end, an end that pushes seal wire 9 is connected to and pushes circle above, and its other end passes the inner chamber of described delivery conduit 15, near the suturing nail 6 in delivery conduit body 5; Have spring part 18 away from being sewn on the propelling movement seal wire of tissue between holding pushing circle and pusher body 19, described front ring for fixing 11 is separately fixed at the upper and lower end of the close described propelling movement circle 12 of pusher body; After pushing joint 10 and the joint 7 of conduit docks, singlehanded forefinger and middle finger are inserted in front ring for fixing 11, thumb is pushed after entering and pushing circle 12, push seal wire 9 suturing nail is pressed into and is sewn tissue, push circle and reset under the effect of spring part.
As shown in Figure 5, pusher 16 can also be singlehanded pistol type pusher, comprise handle 14, handle is positioned at pusher away from the delivery conduit end, an end that pushes seal wire is connected with the pushing plate machine 13 on handle, the other end passes the inner chamber of described delivery conduit 15, near the suturing nail 6 in delivery conduit body 5; There is spring part 18 on the propelling movement seal wire between the propelling movement joint 10 of pushing plate machine 13 and pusher; After pushing joint 10 and the joint 7 of conduit dock, pull pushing plate machine 13, push seal wire 9 suturing nail is pressed into and is sewn tissue, pushing plate machine 13 resets under the effect of spring part.
As Figure 7-8, during for propelling movement, suturing nail 6 penetrates and is sewn tissue and passes the situation that is sewn tissue, and the fixing local enlarged diagram of suturing nail 6 stitching, and the situation after sewing up continuously.
The tissue that the delivery conduit front end will be pressed close to be sewn in the process of releasing suturing nail, the suturing nail competence exertion its in in-house bending and last closed process, otherwise may occur sewing up too shallow and be difficult to closing tissue, or suturing nail has aloft discharged.The similar stapler of principle of the present invention, the also operation principle of similar carpenter's vapour nail hammer, difference is, needs the tissue sewed up soft than plank and multi-layered paper, and only with pushing the closure that can complete under scope tissue.Suturing nail is inserted in tissue, and because Ultimum Ti or polyurethane memory material all have good histocompatibility, its physiological compatibility is better than stitching thread.
Experiment in vitro: after pushing joint 10 and the joint 7 of conduit docking, handle hole through scope inserts stitching devices, by the endoscopic views mirror, the delivery conduit front end of stitching devices is pressed close to the Gaster Sus domestica tissue, select again position, push to push seal wire 9, while pushing as seen, suturing nail 6 penetrates tissue and passes the situation of tissue, and the NiTi suturing nail can complete the stitching of tissue.
Experiment in animal (pig) body: will push joint 10 and dock with catheter adapter 7, the direct oral cavity scope inserts in Gaster Sus domestica, behind selected suture site, handle hole through scope inserts stitching devices, by the endoscopic views mirror, the delivery conduit front end of stitching devices is pressed close to the Gaster Sus domestica tissue, push seal wire, during visible push, suturing nail penetrates tissue and passes the situation of tissue, and the NiTi suturing nail can complete the stitching of tissue.
