Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Based on this practicality
Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, the scope of the utility model protection is belonged to.
As shown in figure 8, the occluder for left auricle induction system of the embodiment in utility model includes delivery sheath 100, expanded
Prop 200, loader 300, hemostatic system 400 and conveying wirerope 500, wherein, delivery sheath 100 can coordinate with expander 200
Constitute heart shedding motion；Heart shedding motion, hemostatic system 400 are sequentially connected and form hollow passage, convey wirerope 500
Wirerope 501 may pass through hollow passage.The occluder for left auricle induction system is used for left auricle of heart PCI, can complete a left side
The loading of atrial appendage occlusion device, the function such as convey, strut, reclaim and discharge.
As shown in figure 1, in the utility model, delivery sheath 100 is via delivery sheath body 101 and delivery sheath sheath
Seat 102 is formed by connecting, and connection between the two is formed with UV glue by ultraviolet light solidification.Delivery sheath body can be divided into three
Section, i.e.,：Delivery sheath body near-end 103, delivery sheath body interlude 104 and delivery sheath body distal end 105, wherein conveying
Sheath body near-end 103 is used for one end that conduit is connected, the one end inserted into the patient of delivery sheath body distal end 105, conveying
Sheath body interlude 104 is one section of body in the middle of delivery sheath body near-end 103 and delivery sheath body distal end 105.
There is the first flexible place 121 in the junction of body near-end and body interlude, have on body interlude
Second flexible place 122, the bendable angle at the first flexible place is 0 °~50 °, and the bendable angle at the second flexible place is
0 °~50 °, and the first flexible place of flexible place 122 and second can not only bend in same plane, can also be in difference
Plain bending, i.e. curvature of space.
The pipe thickness of delivery sheath body is：0.2~0.5mm, tube wall is divided into three layers, respectively internal layer 109, intermediate layer
106 and outer layer 112, the material of the internal layer 109 is PTFE film,

It is fixed；If without radiography hole, during clinical operation, the time that contrast agent retains in diffusion is relatively short, to positioning and determining
Away from having any problem, harder sophisticated cladding material is difficult to manufacture radiography hole, and sophisticated outer layer is smaller using hardness in the utility model
Material, beneficial to manufacture radiography hole.The quantity in radiography hole 108 can be 2-10, be easy to fill the effect that part utilizes contrast agent.And
And delivery sheath body distal end 105 has at least two developing ring 107, to avoid a developing ring from can not showing or embody far
End enters the distance of left auricle of heart, so as to be difficult to the situation for conveying occluder for left auricle, is easy to clinical manipulation personnel observation to assess defeated
Sheath distal end is sent to enter the distance or particular location of left auricle of heart.
As shown in figure 3, expander 200 is formed by connecting via expander body 201 and expander sheath seat 203, loader
300 be to be formed by connecting by protheca seat 401, rear sheath seat 402 and sheath 403 through glue.
As shown in figure 4, loader 400 is to be formed by connecting by protheca seat 401, rear sheath seat 402 and sheath 403 through glue.
As shown in figure 5, conveying wirerope 500 is assembled by wirerope 501, handle 502 and bolt 503.
As shown in fig. 6, hemostatic system 300 is formed by connecting by haemostatic valve 301, connecting tube 302 and threeway 303 through glue.
In the utility model, delivery sheath 100 can match somebody with somebody with expander 200 is combined into heart shedding motion as shown in Figure 7,
Delivery sheath 100 can be sequentially connected with loader 400, hemostatic system 300 and conveying wirerope 500 and constitute a left side as shown in Figure 8
The induction system of atrial appendage occlusion device.
