Abstract

The invention discloses a double-layer drainage device for a neurocranium operation. The drainage device comprises a drainage tube. An opening is formed in one end of the drainage tube, side holes areformed in the other end of the drainage tube, an opening is also formed in the end, provided with the side holes, of the drainage tube, and a movable connection end cover is arranged on the opening.The drainage tube is a double-layer tube body, wherein the side holes are directly communicated with an inner-layer tube body and not communicated with an outer-layer tube body, injection holes are also formed in the outer-layer tube body, the injection holes are opposite to the side holes, and the injection holes are communicated with the outer-layer tube body. The drainage device is simple in structure, and the neurocranium can be conveniently subjected to drug administration while extravasated blood in the neurocranium is conveniently drained.

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...
