Embodiment Construction

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0026] Such as Figure 1-Figure 3 As shown, a puncture cone assembly of this embodiment includes a sleeve 3, a first puncture needle 1 and a second puncture needle 2, the puncture end of the first puncture needle 1 is an arc-shaped structure, and the second puncture needle 2 The puncture end of the puncture needle 2 is a sharp structure; the outer wall of the first puncture needle 1 and the outer wall of the second puncture needle 2 are compatible with the inner wall of the sleeve 3; the sleeve 3 1. Both the first puncture needle 1 and the second puncture needle 2 are made of metal material. The puncture end of the second puncture needle 2 is sharper than that of the first puncture needle 1 , and the puncture end o...

Abstract

The invention relates to a puncture cone needle assembly which comprises a sleeve, a first puncture needle and a second puncture needle. The puncture end of the first puncture needle is of a camberedsurface structure, and the puncture end of the second puncture needle is of a sharp pointed structure; the outer side wall of the first puncture needle and the outer side wall of the second puncture needle are matched with the inner side wall of the sleeve; the first puncture needle is fixed to the interior of the sleeve in a pluggable mode, and the puncture end of the first puncture needle stretches out from one end of the sleeve; or the second puncture needle is fixed to the interior of the sleeve in a pluggable mode, and the puncture end of the second puncture needle stretches out from oneend of the sleeve. When the puncture cone needle starts puncturing, the second puncture needle punctures sin and other tissue; when an intestinal tube or a blood vessel exists in front of the punctureneedles, the second puncture needle can be pulled out and replaced with the first puncture needle, and due to the fact that the end of the puncture section of the first puncture needle is of the cambered surface structure, and the damage to intestinal tubes or blood vessels can be relieved in the puncturing process.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture cone assembly. Background technique [0002] At present, more and more tumor patients are receiving interstitial interstitial radioactive implantation therapy for tumor treatment. The treatment method is usually to puncture the tumor lesion under the guidance of CT, and then put radioactive particles into the tumor lesion through a particle needle. The particle needle is composed of a needle barrel and a needle core. The end of the needle barrel is blunt, and the end of the needle core is sharp, which is beneficial to puncture the skin and tissue. When there are tissues or organs that need to be avoided such as blood vessels or intestinal tubes on the puncture path, doctors often advise patients to give up seed implantation, because serious complications may occur after blood vessel or intestinal tube damage, and even endanger the patient's life. At this t...
