Description

Endoscope suture needle device

Technical field

The present invention relates to a kind of clinical endoscopic suture instruments, more particularly to a kind of endoscope suture needle device.

Background technology

Scope has been promoted at home in recent years, is current clinically widely applied inspection and therapeutic device, so And the process clinically sutured under a large amount of scope, other trepanning is needed, suture instruments is still further placed in and carries out the operation.Such as Can sewing process only be completed via the handle hole of scope, then not only will greatly facilitate and simplify operating process, reduce not Necessary notch and damage are conducive to patient's recovery；The prior art for can through endoscopic technic hole be placed in endoscopic suture instrument Also there is research, but structure is all very complicated, it is inconvenient for operation.

Invention content

Use endoscope suture needle device that endoscopic technic hole is passed through to realize single or multiple continuous sutures and ligation to reach, And purpose simple to operate, the present invention is in the following way：A kind of endoscope suture needle device, including sewing needle, hard seam Wire guide is closed, conducting wire is sutured, the sewing needle is made by Ultimum Ti, and front end is fixed to be suitble to the suture of surgical stapling Aciculiform shape, for the sewing needle by the suture wire guide, the front end of the sewing needle linear shape that can be straightened is located at hard seam It closes within wire guide, can also be pushed out outside suture wire guide, while in shape when shaping, the rear end of sewing needle is placed in suture For wire guide far from being sewn except the tube body at tissue end, the needle point front end of the sewing needle has threading hole, the suture conducting wire Across the threading hole of sewing needle；It is locked ring characterized by further comprising suture, the suture ring that is locked is by non-nickel The twin nuclei that the metal of titanium memorial alloy makes, includes the open loop of a close ring and an accommodated side-by-side, wherein being closed Ring is used to be sleeved on the end of suture conducting wire after suture, and the suture ring that is locked is made to slide into and need to ligature position, described to open Put ring for places suture conducting wire the other end, make suture be locked ring be closed ligature.

The shape of above-mentioned sewing needle front end sizing is round needle shape.

The shape of above-mentioned sewing needle front end sizing is cutting needle shape.

Above-mentioned suture conducting wire is a conducting wire being made of two different colors of line segment, the line segment face for suturing one end Color is different from for tensing the closure line segment color of one end.

The endoscope suture needle device of the present invention, operating process no longer need to reaming or increase notch completion, it is only necessary to by each The handle hole of kind scope, coordinates other clamp device such as clamps that single or multiple continuous sutures and ligation can be realized, greatly simplifies The suture operation of scope, realization can dispose endoscopic suture, promote suture accuracy and quality, operation side fast and reliablely Just, and being realized through endoscopic technic hole meets the operating process of conjunction that can be completed by the endoscopic views.

Specific implementation mode

To keep this programme clearer, now coordinates attached drawing, explain embodiment in detail.Such as Fig. 1, shown in 2,3,4,5, sheet Invention is a kind of handle hole only needed through various scopes, coordinates other clamp device such as clamps that operation can be completed, to real The endoscope suture needle device of existing single or multiple continuous sutures and ligation comprising the sewing needle 3 made by Ultimum Ti, Sewing needle front end 1 is fixed to that the sewing needle shape of surgical stapling, the present apparatus is suitble to further include that the sewing needle of hard material making is led Pipe 4 sutures conducting wire 6 and suture and is locked ring 7, and sewing needle 3 is made by Ultimum Ti, and Ultimum Ti is energy The alloy that the plastic deformation of itself is automatically restored to original-shape is also had in addition to unique shape memory function The excellent characteristics such as wear-resistant, anticorrosive, super-elasticity.The form for the sewing needle front end 1 that Ultimum Ti is made first is shaped To be suitble to the sewing needle shape of surgical stapling, it is the round needle shape for being fixed to surgical stapling in present embodiment, can also shapes For cutting needle shape etc., sewing needle 3 is passed through into suture wire guide 4, is managed when the front end of sewing needle 1 is located at hard suture wire guide 4 When internal, because of the super-elasticity feature of Ultimum Ti, entire sewing needle 3, which can be straightened to be in line, stretches shape, volume very little, It is easy to move in suture wire guide 4, and can be sent into through endoscopic technic hole together with conduit；When sewing needle to deep promote, and by When being pushed out from the tube body at the close suture tissue end of suture wire guide 4, form of the sewing needle front end 1 because of Ultimum Ti Memory performance and be restored to the surgical stapling round needle shape shaped originally at once, needle point front end 2 is sharp to be easy to suture, to profit Suture tissue and the again process outside back stitching to tissue are penetrated in completing round needle；The rear end 5 of sewing needle is placed in the remote of suture wire guide 4 From being sewn except the tube body at tissue end；The sewing needle needle point front end 2 has needle string holes sample threading hole, sutures conducting wire 6 The threading hole of sewing needle needle point front end 2 is penetrated, the two is made of one.

Suture conducting wire 6 is a conducting wire being made of two different colors of line segment, the line segment 10 for suturing one end Color is different from for tensing the closure color of line segment 11 of one end, convenient for being distinguished when suture and bracing wire.

After suture, the suture ring 7 that is locked passes through endoscopic tube 9, and the end for being sleeved on suture conducting wire 6 slides into and needs to tie Position is pricked, suture is locked ring 7 can be with clamped 8 if stainless steel material makes by other metals of non-Ultimum Ti Folder closes, and why is made of non-Ultimum Ti material, is super-elasticity and memory performance because of Ultimum Ti material Make it that can also closure be made to open after folder closes, and the purpose of closure is not achieved.Such as Fig. 3, shown in 4,5, the suture ring 7 that is locked is Twin nuclei side by side includes the open loop 13 of a close ring 12 and an accommodated side-by-side, such as Fig. 3, close ring 12 therein, For the end of the line segment 10 for suturing one end across suture conducting wire, suture is locked ring 7 along suture conducting wire downslide To position, such as Fig. 4 need to be ligatured, the extremity of segment 11 for the suture conducting wire that the other end tenses then is placed into suture and is locked ring It in open loop 13, is then compressed with the clamp of auxiliary 8, Fig. 5 show the suture ring that is locked and closed by folder, sutures The ligated state of conducting wire.

Clamp 8 is a kind of instrument stretched by scope, under scope, by the auxiliary of clamp, can reach drawing seam It closes conducting wire and suture conducting wire interpenetrating and suture will be pressed off be locked ring, the purpose of fixed suture conducting wire.

By Fig. 6 --- sequence shown in Fig. 10, Fig. 6：Round needle passes through tissue, clamp auxiliary pulling to suture conducting wire first, complete It is sutured at the first needle；Fig. 7：The suture of the second needle is completed, preparation carries out suture conducting wire interpenetrating；Shown in Fig. 8：It has been sequentially completed 4 Needle sutures and sutures three times conducting wire interpenetrating；And the suture ring 7 that is locked has slipped down to quasi- ligation position；As shown in figure 9, drawing And the other end for suturing conducting wire feeding suture is locked in the open loop 13 of ring 7, folder closes the suture and is locked ring；Such as figure 10 display ligation are completed.Endoscope suture needle device so as to complete the present invention sutures under scope and continuous multiple spot sutures and folder Icarceration bad mold joint be locked ring ligation conducting wire overall process.
