【技術實現步驟摘要】
(一)
本技術涉及一種內鏡下血管插管穿刺針。(二)
技術介紹
內臟血管內注射藥物、測量壓力及血流動力學研究,內臟血管內血液成分分析等對疾病的診斷和治療起著非常重要的作用。目前主要通過內鏡下穿刺來完成,由于穿刺針針尖非常鋒利,再加上心跳、呼吸及消化道等不自主運動,因此特別容易造成穿刺針針尖穿到血管壁或劃破血管引起大出血及危及生命的并發癥。目前在臨床工作中極少開展此類工作,由此試驗只能在動物身上來完成。本系統可解決上述問題。(三)
技術實現思路
本技術要解決的技術問題是提供一種內鏡下血管插管穿刺針,操作安全性高,使用效果好。為此,本技術采取以下技術方案:一種內鏡下血管插管穿刺針,包括有針體、針尖和針柄,所述針尖和針柄布置在針體兩端,所述針體上套裝有針鞘和針鞘柄,針鞘柄安裝在針鞘尾部,相鄰針柄布置,所述針體和針柄為中空結構,所述針鞘密封安裝在針體上,所述針體前端位于針鞘外側的側壁上開有側孔。所述針體的針尖呈鍥形。所述側孔為兩個,相鄰布置。本技術的工作過程是:在內鏡下選好穿刺點,將所述穿刺針刺入血管,當針體側孔有血液流出,說明穿刺針已經成功刺入血管,這時拔出手柄,將穿刺用導絲沿針柄和針體的空腔插至血管腔內一定深度固定,退出穿刺針;然后將血管留置管沿穿刺用導絲插入血管內,退出穿刺用導絲,固定血管留置管,完成內鏡下血管插管術。本技術的優點是:1、穿刺完即可拔出穿刺針,采用血管留置管留置在血管中,避免了尖銳的針尖劃破血管壁引起的各種危害,使用更安全;2、通過血管留置管注射藥物、采集血液樣本、或測壓及血流動力學研究,更加準確、安全、可靠。(四)附圖說明圖1為本技術結構示意圖; ...
