DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figs. 1-3 As shown, the present invention proposes a liver puncture tract closure device, comprising a delivery sheath 1 and a delivery tube 3. The delivery tube 3 is slidably disposed within the delivery sheath 1. The delivery sheath 1 is made of medical-grade polyethylene material and is composed of different tube diameter specifications from 6F to 14F. The delivery tube 3 is made of medical-grade polyethylene material. The outer circumference of the delivery tube 3 is smaller than that of the delivery sheath 1 and can absorb hemocoagulase-expanded gelatin sponge 2F, and its length is 25cm. A second through hole 6 is provided through the delivery tube 3, and the diameter of the second through hole 6 is 0.90mm.

[0025] like Figs. 1-3 As shown, it also includes an absorbable hemocoagulase-expanded gelatin sponge 2, which is slidably disposed within the delivery sheath 1. The absorbable hemocoagulase-expanded gelatin sponge 2 is made of medical gelatin sponge and contains hemocoagulase powder. The dissolved hemocoagulase has a hemostatic effect in the liver. The gelatin sponge will be absorbed by the liver after 4-5 weeks in the liver. The outer circumference of the absorbable hemocoagulase-expanded gelatin sponge 2 is 1F smaller than the outer circumference of the delivery sheath 1. It is composed of different length specifications from 2cm to 8cm and is suitable for liver puncture channels of different lengths. A first through hole 4 is provided through the absorbable hemocoagulase-expanded gelatin sponge 2, and the diameter of the first through hole 4 is 0.90mm.

[0026] like Figs. 1-3 As shown, a delivery end 5 is fixedly provided at the front end of the delivery tube 3. The delivery end 5 and the absorbable hemocoagulase-expanded gelatin sponge 2 are movably connected and abut each other. A first metal mark 7 is fixedly provided at the front end of the delivery sheath 1. A second metal mark 8 is provided at the movable connection between the front end of the delivery end 5 and the absorbable hemocoagulase-expanded gelatin sponge 2. The outer perimeter of the delivery end 5 is consistent with the outer perimeter of the absorbable hemocoagulase-expanded gelatin sponge 2.

[0027] In practical use, after the percutaneous liver biopsy interventional treatment is completed, the guidewire used in the percutaneous liver biopsy is retained in the liver. According to the model of the liver biopsy kit used during the interventional treatment, such as 8.5FF, the length of the intrahepatic puncture tract is 4cm. The liver puncture tract sealing kit is selected with an 8F delivery sheath 1 and a 3cm long absorbable hemocoagulase-expanding gelatin sponge 2.

[0028] Along the first through hole 4, the intrahepatic reserved skin liver puncture operation guide wire is slowly introduced, when the intrahepatic reserved skin liver puncture operation guide wire is exposed through the delivery tube 3, the intrahepatic reserved skin liver puncture operation guide wire is slowly implanted into the delivery sheath 1, the first metal mark 7 and the second metal mark 8 are monitored under fluoroscopy, when the delivery sheath 1 reaches the pre-closed puncture path, the delivery is stopped, positioning is performed under fluoroscopy, the first metal mark 7 and the second metal mark 8 are ensured to be in the liver, at this time, contrast agent can also be injected along the second through hole 6 in the delivery tube 3, whether the length of the pre-closed puncture path is consistent with the length of the selected absorbable thrombogen expanded gelatin sponge 2 is determined again, the intrahepatic reserved skin liver puncture operation guide wire is withdrawn, the delivery tube 3 is slowly pushed into the liver, and the delivery sheath 1 is slowly withdrawn, the absorbable thrombogen expanded gelatin sponge 2 is slowly released in the liver puncture path, when the planes where the first metal mark 7 and the second metal mark 8 are located overlap, the absorbable thrombogen expanded gelatin sponge 2 is completely released in the liver puncture path, the delivery sheath 1 and the delivery tube 3 are withdrawn. When the absorbable thrombogen expanded gelatin sponge 2 meets water, blood, contrast agent or bile, the absorbable thrombogen expanded gelatin sponge 2 is expanded, the expanded absorbable thrombogen expanded gelatin sponge 2 compresses the liver puncture path, and the thrombin dry powder in the absorbable thrombogen expanded gelatin sponge 2 is also dissolved, and the dissolved thrombin has a hemostatic effect in the liver.

[0029] When positioning, contrast agent is injected along the second through hole 6 in the delivery tube 3, the absorbable thrombogen expanded gelatin sponge 2 absorbs the contrast agent, at this time, a strip-shaped high-density shadow can be seen in the liver under fluoroscopy, that is, the absorbable thrombogen expanded gelatin sponge 2 that absorbs the contrast agent, so that the closure of a larger puncture path or cavity in the liver is easily and quickly completed.

[0030] The above describes the utility model and its implementation, which is not restrictive, and the drawings only show one of the embodiments of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the creative purpose of the utility model, similar structure modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
