Neurocranium operation drainage device facilitating drug injection

Abstract

The invention discloses a neurocranium operation drainage device facilitating drug injection. The neurocranium operation drainage device comprises a drainage pipe, one end of the drainage pipe is opened, a side hole is formed in the other end of the drainage pipe, the end with the side hole is also opened, and the opening is provided with a movable connecting end cap; the pipe body is provided with a double-layer structure, the side hole is directly connected with the inner layer pipe and is not connected with the outer layer pipe, the outer layer pipe body is provided with an injection hole opposite to the side hole, the injection hole is directly connected to the portion between the outer layer pipe and the inner layer pipe, net-shaped branch pipes communicated with one another are further arranged between the inner layer pipe and the outer layer pipe, inlets of all the branch pipes are located at the upper portion of the pipe body, and outlets of all the branch pipes are located atthe lower portion of the double-layer pipe walls and are all connected to the injection hole through a sealing cavity. The portable neurocranium operation drainage device is simple in structure, extravasated blood in the neurocranium can be very conveniently drained, and meanwhile, the neurocranium can be conveniently subjected to drug application.

Description

technical field [0001] The present invention relates to a surgical instrument. Background technique [0002] The drainage device is a commonly used surgical instrument for the drilling and drainage of intracranial hematoma. Generally speaking, the drainage tube is mainly a ventricular drainage tube, and the drainage tube is a tube with a side hole at the end of the tube. The other end of the tube can flow out, thereby achieving the effect of reducing the patient's brain pressure. During the operation, the medicine is directly injected into the drainage tube, so that the medicine is easily mixed with the residual blood in the tube, which affects the efficacy of the medicine. [0003] One end of the existing drainage tube is closed, and such a structure is not convenient for cleaning the used pipeline. Meanwhile, the current cleaning of the drainage tube is manual cleaning, and its cleaning efficiency is low. Contents of the invention [0004] The purpose of the present in...
