Brief description of the drawings
By description referring to the drawings to the embodiment of the present invention, above-mentioned and other purpose of the invention, feature and
Advantage will be apparent from, in the accompanying drawings：
Fig. 1 shows the structure sectional view of the present invention.
Embodiment
Below based on embodiment, present invention is described, but the present invention is not restricted to these embodiments.
The directional terminology " near-end " that is used in the present invention, " distal end " be meant that centered on heart, when in use, conveying
Sheath one end near apart from heart is called near-end, and one end remote apart from heart is called distal end.
The present invention provides a kind of exhaust excellent atrial septal defect intervention conveying sheath, as shown in figure 1, it includes：The He of epitheca 1
Interior sheath 2, the epitheca 1 is placed on the interior outside of sheath 2 and is slidably connected with interior sheath 2, and the epitheca 1 is that hollow and two ends have
Mouthful, the epitheca 1 is provided with steam vent 3, and the steam vent 3 is 1~2cm at the proximal outlet of epitheca 1；Wherein, when interior sheath
After epitheca stretches out, the interior sheath and epitheca are brought into close contact, steam vent not with epitheca outlet；When interior sheath 2 is pulled out from epitheca 1
When going out, steam vent 3 and the outlet of epitheca 1.If the distance at the proximal outlet of epitheca 1 of steam vent 3 is less than 1cm, epitheca 1 is near
Bring out mouth and steam vent 3 causes outlet port intensity decreases jointly, be easily deformed, if steam vent 3 is apart from the proximal outlet of epitheca 1
Place's distance is more than 2cm, then hypertelorism, and exhaust can not rapidly, in time, completely.
When carrying out atrial septal defect intervention operation, sheath will be conveyed first and sends into specified location along the track that seal wire is set up
Afterwards, interior sheath 2 and seal wire are removed together, then opens the three-way valve of conveying sheath distal.During interior sheath 2 is removed, due to the heart
Dirty internal pressure is higher than external pressure, and gas can be discharged, but the proximal outlet of epitheca 1 is easily adherent with cardiovascular organization generation,
Exhaust problem is caused or not thorough, by setting steam vent 3 on epitheca 1, when interior sheath 2 is extracted, even if the proximal outlet of epitheca 1
Adherent with cardiovascular organization, gas can still be discharged from steam vent 3, and exhaust is rapid, complete, without withdrawing conveying sheath or rotation repeatedly
