Description

Left auricle plugging device containing 3D printing inner filling piece

Technical Field

The utility model belongs to the technical field of and medical instrument, concretely relates to contain left auricle plugging device that filler was filled in 3D printed.

Background

At present, a plugging device can be placed in a left auricle by a catheter intervention method, so that thrombosis of the left auricle caused by atrial toss is prevented, and stroke caused by the fact that the thrombosis ascends to the brain is avoided; or prevent the thrombus from reaching other parts of the body through the blood circulation system of the human body, and causing systemic embolism. Such a left atrial appendage occluder can roughly be divided into an integrated occluder and a split occluder structurally, the split occluder usually comprises a fixing frame and a sealing disc which are fixedly connected with each other, the fixing frame is arranged in a left atrial appendage cavity to fix the whole occluder, and the sealing disc seals the mouth of the left atrial appendage and is used for blocking blood flow from flowing into the left atrial appendage cavity.

For a split type stopper, the sealing disc inside the stopper is placed on the left atrial appendage, but because the mouth of the left atrial appendage of a human body has difference, the adhered filler is required to be supplemented frequently, but in the actual operation process, the complexity of clinical use is increased.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is in order to improve the availability factor.

The utility model provides a left auricle plugging device who contains 3D and prints interior filler, its characterized in that: the mount including sealed dish and perpendicular to sealed dish, sealed dish is including the centre of a circle installed part that is located the sealed dish centre of a circle, sealed dish includes that a plurality of roots are the brace rod that the rib set up by the radial radiant type in sealed dish centre of a circle, be equipped with the one deck seal membrane on the brace rod of sealed dish, mount and sealed dish are in the centre of a circle installed part threaded connection of sealed dish, the excircle of sealed dish is equipped with round excircle erection circle, excircle erection circle is connected with the outer end of brace rod, the excircle terminal surface of excircle erection circle is equipped with round mounting groove, the soft buffering packing ring of the rotatory installation round of mounting groove of excircle erection circle.
