Drainage device with injection partition plates for neurocranial surgery

Abstract

The invention discloses a drainage device with injection partition plates for a neurocranial surgery. The 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 of a double-layer structure, the side holes are directly connected to an inner tube and are not connected to an outer tube, injection holes are formed in the outer tube body and directly connected to the bottom position between the outer tube and the inner tube, net-shaped branch tubes communicated with each other are arranged between the inner tube and the outer tube, inlets of each of the branch tubes are connected to a first partition plate between the two layer tubes, outlets of each of the branch tubes are connected to a second partition plate between the two layer tubes, and a first annular groove and a second annular groove are respectively formed in the upper portion and the lower portion of the space surrounded by tube bodies at the two sides. The drainage device has a 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 purpose of the present in...
