Split abdominal cavity puncture device for ventricle-peritoneal shunting operation

Abstract

The invention provides a split abdominal cavity puncture device for a ventricle-peritoneal shunting operation. The split abdominal cavity puncture device is composed of a needle core made of a medical plastic material and a split sleeve and has a length of 8 to 30cm; the needle core has a length of 7.5 To 27cm and a diameter of 0.3 to 0.8cm, the tail portion of the needle core is provided with a handle with a diameter of 2 to 4cm and a length of 2 to 4cm, an upper disc is provided with antiskid patterns which facilitates holding during puncturing for powerful puncturing, and the head portion of the upper disc is in the shape of a sharp three diamond which facilitates penetration of a peritoneum; the split sleeve has a length of 6 to 25cm, an internal diameter of 0.3 to 0.8cm and a thickness of 0.5 to 1mm, the pipe body of the split sleeve is provided with scales, and the split sleeve can predict the depth of entry into the peritoneum during the puncturing; and at the same time, the split sleeve is formed by bonding two semicircular pipes, the two sides of the tail portion of the split sleeve are provided with two handles in parallel, when the handles are pulled forcefully, the split sleeve can be easily split, and the head portion of the split sleeve is polished and dulled so that secondary damage is not caused during the puncturing. The split abdominal cavity puncture device provided by the invention is used for the ventricle-peritoneal shunting operation. Compared to a conventional abdomen opening and tube arrangement operation, the operation time is greatly shortened, the possibility of complications is reduced, the operation is simple and safe, the operation success rate is high, no complications are caused, and the popularization is facilitated.

Description

technical field [0001] The present invention relates to a splittable peritoneal puncture device used for ventriculo-peritoneal shunt surgery and the prepared medical device products, in particular, the splittable peritoneal puncture device involved in the present invention has a needle core made of medical plastic material and It is composed of a split sleeve, and the peritoneal puncture in the ventriculo-peritoneal shunt operation is simple and less traumatic. After the puncture, the trocar is completely withdrawn without affecting the operation of the shunt tube. Background technique [0002] Ventriculoperitoneal shunt is one of the treatment methods for hydrocephalus in neurosurgery, but the shunt implantation process is an important reason for inducing infection, especially the placement of the abdominal cavity is very important. The traditional method is to directly open the abdomen and insert the abdominal end of the shunt under direct vision, but this method takes a l...
