Problems solved by technology

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 will affect the efficacy of the medicine
[0003] One end of the existing drainage tube is closed. Such a structure is not convenient for cleaning the used pipeline. At the same time, the current cleaning of the drainage tube is manual cleaning, and its cleaning efficiency is low.

Abstract

The invention discloses a double-layer drainage device with injection holes for a neurocranial surgery. The double-layer drainage device comprises a drainage tube, an opening is formed in one end of the drainage tube, side holes are formed in the other end of the drainage tube, and an opening is also formed in the end where the side holes are formed and is provided with a movably connected end cap; a tube body is provided with an outer tube and an inner tube, the side holes are directly connected to the inner tube and are not communicated with the gap formed between the outer tube and the inner tube, the injection holes are formed in the outer tube and communicated with the gap formed between the outer tube and the inner tube, two or more partition plates in the lengthwise direction of thetube body are arranged in the gap, the partition plates divide the gap into a plurality of independent spaces, and the injection holes are formed in the bottom of each space; a drain board is arranged on the upper portion of the gap, a plurality of water dripping holes are formed in the drain board, and at least one water dripping hole is formed in each space. The double-layer drainage device hasa simple structure, and can conveniently drain the extravasated blood in a neurocranium and facilitate the use of medicines to the neurocranium.

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 object of the present inv...
