摘要：
The present invention provides an automatic buckling sheath of tumor needle, which comprises a needle apparatus having a needle head base and a soft tube, and the needle head base is configured with a U-shaped body base configured with left and right pivoting holes an elastic clip member comprising an elastic h-shaped base and a long convex plate assembled together, and the h-shaped base is pivoted with the two pivoting holes of the U-shaped body base by its two studs a protection sheath comprising a base plate and a receiving space, and the base plate is configured with an engaging groove wherein the h-shaped based may be pivoting within the U-shaped body base and the rear protrusion of the long convex plate is engaged with the engaging groove of the base plate to tightly combine the protection sheath with the h-shaped base and, because of the structural deformation of h-shaped base during operation, there will be an angle variation causing an elastic force, so as to immediately buckle the used needle into the protection sheath by turning.本發明為一種腫瘤穿刺針的自動扣合護套,包括一刺針裝置,包括一針頭座及一軟管,針頭座設有一本體U形座,本體U形座設有左右樞孔;一彈性夾件,包括相組設之彈性一h型座體及一長凸形板,h型座體以其兩樞軸與本體U形座兩樞孔相樞接;一保護套,包括一基板及一套置空間,基板設有一卡凹槽;h型座體可在本體U形座內樞轉,而該長凸形板之背後凸部卡結於該基板之卡凹槽,使保護套穩固結於h型座體,並藉h型座體因操作時結構形變而有夾角變化,並藉以產生彈性力,將用畢之刺針在撥動下立刻扣入保護套內。10‧‧‧刺針裝置11‧‧‧針頭座12‧‧‧管支撐套13‧‧‧蝴蝶翼片131‧‧‧套固塊14‧‧‧軟管15‧‧‧針槽16‧‧‧刺針17‧‧‧本體U形座171‧‧‧垂直凹槽172‧‧‧樞孔20‧‧‧彈性夾件21‧‧‧h型座體22‧‧‧長凸形板30‧‧‧保護套31‧‧‧基板32‧‧‧護套基板33‧‧‧側板34‧‧‧端板35‧‧‧套置空間36‧‧‧護條37‧‧‧撥動部
