Hemostatic suppository for blocking organ puncture path

Abstract

The invention discloses a styptic blocked plug for a viscera puncture path, which comprises a shell and an interior core, wherein the shell is provided with an opening and is made of a hydrophilic and resolvable organism degradable material, and the interior core is arranged in the shell and is mainly made of gelatin sponge. The styptic blocked plug for the viscera puncture path of the invention can not only ensure that the gelatin sponge takes the effect of hemostasia immediately, but also prevent the gelatin sponge from absorbing water prematurely to bulge. Therefore, the gelatin sponge is easily pushed to the deep part of the puncture path and cannot be dashed out easily by blood, all gelatin sponge grains are released to take the durative effect of hemostasia after the shell thaws. The styptic blocked plug has accurate, reliable, good and thorough effects of blocking and hemostasia, which is capable of curing maniple hemorrhage of the puncture path effectively and reducing or getting rid of the risk of secondary hemorrhage and massive haemorrhage; the styptic blocked plug also has a better styptic effect on the massive haemorrhage of the puncture path; and the styptic blocked plug has the advantages of wide material resource, low cost, simple preparation, convenient use, no any toxic and side effect and wide application prospect.

Description

Technical field [0001] The invention relates to the field of medicine, in particular to a hemostatic plug for organ puncture tract. Background technique [0002] Interventional therapy is a method of inserting special medical devices into specific parts of the human body for disease diagnosis and treatment under the guidance of medical imaging equipment. Percutaneous puncture is the basis of interventional therapy, and its purpose is to establish channels (including vascular and non-vascular channels) to complete the follow-up diagnosis or treatment process. In recent years, percutaneous organ biopsy (such as liver, spleen, kidney, etc.), percutaneous tumor local treatment (such as radiofrequency ablation, chemical ablation, radioactive seed implantation, etc.) and percutaneous catheter placement interventional therapy (Such as portal vein branch embolization, intraportal thrombolysis, local infusion chemotherapy, hepatic vein patency, etc.) are increasingly widely used in clini...

AI Technical Summary

Problems solved by technology

However, the above method has the disadvantages of incomplete hemostasis, unreliable hemostatic effect, and the risk of secondary bleeding, and it cannot achieve the hemostatic effect for massive bleeding from the puncture tract.

Especially when gelatin sponge particles are used to block the puncture tract for hemostasis, because the gelatin sponge particles absorb water and expand rapidly, they often over-swell before being pushed to the deep part of the puncture tract and cannot continue to push, and because of the high pressure in the puncture tract, scattered Gelatin sponge particles are easily washed out of the puncture tract by blood, resulting in incomplete blockage and hemostasis, resulting in serious consequences such as secondary bleeding or patient death

In addition, the above-mentioned process also has unfavorable factors such as complex operation, time-consuming, and possible secondary damage to the puncture tract.
