The invention belongs to medical instrument scope, it is related to being used for the device of substantial viscera surface of a wound Suture hemostasis in a kind of operation.As shown in Figure 1, the device includes the coil 1 of head end, and the pusher 2 at middle part and the grip assist device 3 at rear portion, three parts composition.2 and 3 collectively form the main body of pusher.Suture needle and its connected suture are included in 1, the front is smooth temporarily to stop blooding to be adjacent to the surface of a wound, after have card slot that can connect pusher head end, convenient directly dismounting, more to renew the demand switched in needlework and different type needlework art after suturing.Rotation needle in 2 carries undercut, can fix and push 1 needle and line, and with profit, it advances along defined route；It docks with crochet hook after suture needle and company enter deep tissue with the suture of its rear end, and is taken out of from deep tissue by crochet hook, that is, complete primary suture.Bleeding part, which can be oppressed, after stitching unstrument link seam loop of the present invention plays temporarily hemostasis purpose, and the suture in coil is sent to tissue deep without tear failure tissue in turn, the function of completing the sewing hemostasis of tightening blutpunkte surrounding tissue is particularly suitable for uncertain blutpunkte and is unable to the oozing of blood surface of a wound of through and through suture.The present invention really belongs to innovation in structure design etc., there is no like instrument currently on the market, highly practical, and has preferable market prospects.
Description
Technical field
The present invention relates to the devices that substantial viscera surface of a wound Suture hemostasis is used in a kind of open abdomen or laparoscopic surgery, especially
It is suitable for can not the through and through suture surface of a wound and uncertain blutpunkte oozing of blood position.
Background technology
Liver is human body maximum blood reservior official, and the bottleneck of operation on liver is stopped blooding in art.But since liver belongs to substantive
The crisp internal organs of matter, sewing hemostasis technology is more demanding, especially under hysteroscope operate when can not the through and through suture surface of a wound bleeding control,
Traditional instruments are difficult to play a role, and need conversion into open surgery in the case of more, and many resistances are brought for the use of hysteroscope.Therefore urgently
A kind of instrument of quick-acting haemostatic powder is needed to help to realize the effect of similar Suture hemostasis.
Invention content
The technical problem to be solved by the present invention is to overcome the above-mentioned deficiency in the presence of the prior art, and provide a kind of reality
With prominent function, reasonable in design, the instrument of surface of a wound quick-acting haemostatic powder can be facilitated.
The present invention solves the used technical solution of above-mentioned technical problem and is characterized in that：As shown in Figure 1, the device includes head
The coil 1 at end, the pusher 2 at middle part and the grip assist device 3 at rear portion, three parts composition.2 and 3 collectively form pusher
Main body.Suture needle and its connected suture are included in 1, the front is smooth temporarily to stop blooding to be adjacent to the surface of a wound, after have card slot that can connect
Connect pusher head end, convenient directly dismounting, more to renew the demand switched in needlework and different type needlework art after suturing.
Rotation needle in 2 carries undercut, can fix and push 1 needle and line, and with profit, it advances along defined route；As suture needle and Lian Yuqi
The suture of rear end is docked with crochet hook after entering deep tissue, and is taken out of from deep tissue by crochet hook, and primary suture is completed.
Bleeding part can be oppressed after stitching unstrument link seam loop of the present invention and plays temporarily hemostasis purpose, and in turn will
Suture in coil is sent to tissue deep without tear failure tissue, is particularly suitable for uncertain blutpunkte and cannot run through
The oozing of blood surface of a wound of suture.
The invention has the advantages that compared with prior art, there is following positive effect：Utility function protrudes, and can have
Suture is realized in effect ground for the surface of a wound that can not run through of substantial viscera, is particularly suitable for the feelings that routine operation cannot be completed under hysteroscope
Condition, avoids row conversion into open surgery due to hemostasis is not thorough or not in time, and operating aspect shortens operating time, improves efficiency.This
Real invention, it is reasonable in design, more suit the needs of surgery of liver clinical treatment.
The present invention really belongs to innovation in structure design etc., there is no like instrument currently on the market, highly practical, and has
Preferable market prospects.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings and by embodiment.
Embodiment：
As shown, the present invention (especially endoscope-assistant surgery) in abdominal operation uses.As illustrated in figs. 2-4, before use
It needs that first the card slot 8 in card slot face 9 in Fig. 2 " coil " is connected to the buckle 16 of Fig. 3 " pusher " head end and is fixed, i.e.,
Hemostatic suture device is installed, while the safety switch 28 that should be opened on Fig. 4 " handle " is spare.When finding surface of a wound bleeding, directly
Connect the smooth surface 7 in Fig. 2 coils is adjacent to out/oozing of blood position to be to play temporary anastalsis.Then hold each finger of hand pull together by
The excitation handle 23 in Fig. 4, handle is pressed to convert curable grip to push power by the power transmission seal wire 22 being fixed on 21 on pulley
Transmission shaft stress plate 27 is pushed forward, and then pushes transmission shaft 20；Transmission shaft turns round 19 rotation push axis by the spinning in Fig. 3
18, and then rotation needle 12 is made to utilize the wire casing 13 in it that the rotation needle 3 in Fig. 2 and suture 5 is driven to enter deep tissue, while also cooperateing with
Crochet hook push rod 14 is set to push crochet hook 10 to deep tissue；When 3 enter with 10 tissue certain depth after want to cross, and 3
Directly stick into the crochet hook slot 11 in 10；The return spring 17 of pusher pushes 18 to be rotated back to original position and take 10 Hes out of at this time
12, while 19 send out " Ka Ta " prompt tone, that is, indicate that suture finishes, rear unclamp holds finger, and slightly lifting stitching unstrument is received backward
Calking line, rear common biological trimming after clamping suture, that is, complete primary suture.The return spring 25 on handle 26 exists simultaneously
I.e. preceding pushing handle stress plate 24, makes transmission shaft 20 and its stress by the backward thrust of return spring in Fig. 3 17 after curable grip removal
Plate 27 resets.If you need to continue to suture, repeat the above steps after more emat coil.
Above-described embodiment is highly preferred embodiment of the present invention, the embodiment can meet the bleeding surface of a wound suture the needs of and
The time can utmostly be shortened, avoid leading to many operation risks because of bleeding.The embodiment not makees any form to the present invention
Limitation, the technical spirits such as all structure, feature and principles according to the present invention any simply change to what above-described embodiment was made
Change, equivalent variations and modification, belong to the scope of the present invention.
