The utility model discloses a hard channel puncture needle at the abdominal end of the ventriculoperitoneal shunt pipe, which comprises a sleeve and a needle core which are used together; the sleeve is a hollow cylindrical structure which can be inserted into the needle core and the shunt pipe; an opening is arranged on the cylinder wall of the sleeve along the axial direction through the two ends of the sleeve for withdrawing from the shunt pipe after the abdominal end of the shunt pipe is implanted The sleeve. The utility model is applicable to the implantation of the abdominal end of the shunt pipe in the ventriculoperitoneal shunt operation. During the operation, the shunt pipe is first sneaked from the subcutaneous to the umbilical part, and a small incision is made at the umbilical part, about 0.5 \u2011 1cm. The shunt pipe is led out from the incision, and the pneumoperitoneum is established through the incision. The puncture needle with the core of the puncture needle of the utility model is punctured into the abdomen through the incision, and the core of the needle is extracted, and then the abdominal end of the shunt pipe is punctured rapidly The needle sleeve was implanted into the abdominal cavity, and finally the needle sleeve was withdrawn, that is to say, the abdominal end of the shunt tube was implanted. The utility model has the advantages of reducing the operation trauma, shortening the operation time, simplifying the operation process, etc.
【技术实现步骤摘要】
脑室腹腔分流管腹腔端硬通道穿刺针
本技术涉及医疗设备领域,特别涉及一种脑室腹腔分流管腹腔端硬通道穿刺针。
技术介绍
在脑室腹腔分流术中,分流管由头部沿皮下潜行至腹部,其腹腔端需植入腹腔内,以往多采用开腹手术,创伤较大,且留有明显瘢痕。随着腹腔镜技术的开展应用,部分外科医师采用腹腔穿刺方式将分流管腹腔端植入腹腔内,因此,提供一种操作简单、安全性高的穿刺针很有必要。
技术实现思路
本技术的目的是克服现有技术中的不足,提供一种脑室腹腔分流管腹腔端硬通道穿刺针,减小了手术创伤,使腹部瘢痕明显减小,并且缩短了手术时间,简化了操作流程。本技术所采用的技术方案是:一种脑室腹腔分流管腹腔端硬通道穿刺针,包括配合使用的套筒和针芯;所述套筒为能插入所述针芯和分流管的空心圆筒形结构;所述套筒的筒壁上沿轴向开设有贯穿所述套筒两端面的开口,用于所述分流管腹腔端植入完成后从所述分流管上撤出所述套筒。进一步的,所述针芯的上端面设置有第一把手,便于借力穿刺入腹。进一步的,所述套筒的上端面设置有与所述第一把手外形相匹配的第二把手,使得穿刺时所述套筒不会脱离所述针芯,同时,便于借力。本技术的有益效果是:本技术适用于脑室腹腔分流术中分流管腹腔端的植入操作,术中首先将分流管由皮下潜行至脐部,脐部做小切口,约0.5-1cm,分流管由该切口引出,通过该切口建立气腹,取本技术穿刺针带针芯由该切口穿刺入腹,抽出针芯,而后迅速将分流管腹腔端由穿刺针套筒植入腹腔内,最后将穿刺针套筒撤出,即完成本次分流管腹腔端植入 ...
