Detachable image-guided puncture device

Abstract

The invention relates to a novel detachable image-guided puncture device and a production method and application thereof. The device can be directly used for directional positioning of tumor ablation, percutaneous puncture tumor biopsy, intra-tumor intrathecal injection, intervertebral disc puncture decompression, intervertebral disc puncture ablation and the like and can be used for focuses with the depth being more than 10cm. The device can be used for performing next clinical operation flexibly and is more convenient for radio-frequency ablation and seed implantation; the device is reusable but only suitable for single-diameter needles. The device is safe, effective, easy to control, highly practical, simple in production process, low in production cost and remarkable in effect, is a significant improvement on the existing puncture device, is higher in usability and safety and easy to popularize and apply, is more suitable for large-scale production of the pharmaceuticals industry and clinical application of interventional therapy and has good application prospect, the application of the product system in the prior art is expanded, and significant social and economic benefits can be created within short time.

Description

technical field [0001] The present invention relates to the technical field of medicine, in particular to a directional positioning device in the technical field of interventional therapy, more specifically to a detachable puncture device capable of directional positioning under image guidance, and more specifically to It relates to a detachable image-guided puncture device capable of directional positioning. Background technique [0002] 1. Overview of interventional therapy [0003] Interventional treatment is an emerging treatment method between surgery and medical treatment, including endovascular intervention and non-vascular intervention. After decades of rapid development, it has now become the three pillar clinical disciplines together with surgery and internal medicine. To put it simply, interventional therapy is to make a small channel with a diameter of several millimeters on the blood vessel or skin without surgical exposure of the lesion, or through the origin...

AI Technical Summary

Problems solved by technology

[0045] ⑤High operation success rate and low mortality rate; according to relevant statistics, the success rate of interventional therapy is as high as 90%, while the mortality rate is almost zero

[0060] China's research and application status: DCbead has not yet been approved to enter the Chinese market, but the research on drug-loaded microspheres has always been one of the hot spots in the field of pharmaceuticals and interventional radiology in China. Many types have been developed, including 5-fluorouracil polylactic acid microspheres, Doxorubicin sodium alginate microspheres, ion-exchange microspheres containing pingyangmycin, cisplatin microspheres, and compound zedoary oil microspheres containing traditional Chinese medicine ingredients have initially shown certain curative effects in animal experiments, but they are all in the In the preclinical research stage, there is still a big gap from the actual clinical application

[0061] 2. Radioembolization

The disadvantage is that the level of tumor ablation therapy in various regions of China is not the same, lack of standardization, and there is a tendency to blindly expand indications; in addition, there is still a lack of multi-center prospective controlled studies comparing it with other treatments

According to literature search, so far, no technical reports on new detachable image-guided puncture equipment have been found.
