Endodural flushing drainage tube for treating spinal cord injury or infection and use method of endodural flushing drainage tube

Abstract

The invention relates to an endodural irrigation and drainage tube for treating spinal cord injury or infection and a use method thereof, a main body of the irrigation and drainage tube is divided into a first conveying channel and a second conveying channel which are parallel to each other by a longitudinal partition plate to form a double-lumen tube structure; after the flushing drainage tube penetrates through the epidural sac, an injury focus is covered through the inclined end face of the inner water outlet and the position difference between the inner water outlet and the inner water inlet, and the injury focus in the epidural can be directly flushed and treated through a nutrient solution conveyed through the first conveying channel. An oxygen-containing nutrient solution and various nerve and blood vessel growth factors and antibiotics are provided for the injury focus, and meanwhile, toxic substances such as local free radicals, inflammatory factors and bacteria are drained out, so that a microenvironment suitable for cell repair and regeneration and blood vessel regeneration is created for the injury focus; the outer contour of the section of the flushing drainage tube body is of an olive-shaped structure, the transverse diameter is short, and a puncture hole of an epidural sac can be closed easily after the tube is pulled out. The structure is simple, operation is convenient, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an intradural flushing and drainage tube for treating spinal cord injury or infection and a method for using the same. Background technique [0002] The spinal cord is the channel connecting the central and peripheral nerves, and it is the key link in transmitting the commands of the brain to various parts of the human body. Spinal cord injury is usually the result of an external force on the spine, and it can also be the result of diseases such as inflammation, tumor, and vascular disease. [0003] Spinal cord injury, disease and infection are a serious threat to human health, and its continuous development often leads to paraplegia or death, but there is no ideal treatment. A key reason is vascular embolism, ischemia and hypoxia at the injury site, and the increase of free radicals, inflammatory factors, bacteria and other factors that are not conducive to ...

Problems solved by technology

[0005] However, limited by the deep hidden characteristics of the anatomical location, as well as its complex and weak autologous structural characteristics, the prior art lacks an effective measure and treatment that can directly perform continuous irrigation and drug administration on the dura mater after passing through the dura mater. instrument
