Take pjncture needle resistance to compression and prevent stifled spinal surgery wound silica gel drainage tube

带穿刺针抗压防堵脊柱手术伤口硅胶引流管

Abstract

一种带穿刺针抗压防堵脊柱手术伤口硅胶引流管,其特征在于:包括引流管(20)、连接于所述引流管(20)的管口的穿刺针(10);所述引流管(20)靠近穿刺针(10)的部分为连接区,其余部分为术野区,术野区的管壁开有多个内外贯通的侧孔(21),所述引流管(20)内壁凸出设有多个均匀分布的凸筋(22)。具有如下优点:自带穿刺针,所述穿刺针为可掰直或弯曲且有一定可塑性的金属针,有一定弹性,在穿刺针与硅胶连接处剪断即可,操作及其简单方便;引流管自带侧孔,避免手工开侧孔,减少工序;引流管内壁带有凸筋,即使引流管受挤压也有凸筋支撑一定高度,防止引流管受挤压堵塞;引流管在术野区的留置长度可根据需要裁剪,适应不同病人的术野区。
The utility model provides a take pjncture needle resistance to compression and prevent stifled spinal surgery wound silica gel drainage tube which characterized in that: including drainage tube (20), connect in orificial pjncture needle (10) of drainage tube (20), part that drainage tube (20) are close to pjncture needle (10) be the joining region, and all the other parts be the wild district of art, and the wild pipe wall of distinguishing of art division has side opening (21) link up inside and outside a plurality of, drainage tube (20) inner wall protrusion is equipped with a plurality of evenly distributed protruding muscle (22). Has following advantage: from taking the pjncture needle, the pjncture needle has certain elasticity for breaking off with the fingers and thumb directly or crooked and having the metal needle of certain plasticity, pjncture needle and silica gel junction cut can, operation and simple and convenient, the drainage tube is avoided manual and is opened the side opening from taking the side opening, reduces the process, the drainage tube inner wall has protruding muscle, even the drainage tube receives the extrusion also to have protruding muscle to support a take the altitude, prevents that the drainage tube is stopped up by the extrusion, the drainage tube is kept somewhere length and can be tailor as required art wild district, adapts different patients' the wild district of art.
