Problems solved by technology

However, because the drainage tube is relatively thin and the drainage route is long, it is very easy to cause infection of the drainage tube from the puncture port, and even cause the infection to retrograde into the brain, leading to central intracranial infection, resulting in very serious consequences

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, a schematic view of the structure of the lumbar drainage puncture needle of the present invention is provided, figure 2 A schematic diagram of the structure after the puncture needle is connected with the lumbar drainage tube is given, image 3 gives figure 2 The enlarged cross-sectional view of area A in the middle shows that the lumbar drainage puncture needle that can establish a subcutaneous tunnel is composed of a lumbar drainage tube 1 and a puncture needle 2. The two ends of the lumbar drainage tube 1 are pointed inner ends 3 and inserted into The outer end 4 in the drainage bag, the pointed inner end 3 is used to be inserted into the patient's lumbar pool, the inside of the lumbar pool drainage tube 1 is a drainage cavity 5, and the inner end 3 of the lumbar pool drainage tube 1 is inserted into the patient'...

Abstract

A lumbar cistern drainage puncture needle capable of building a subcutaneous tunnel comprises a lumbar cistern drainage tube and a puncture needle, the two ends of the lumbar cistern drainage tube are the inner end and the outer end respectively, and the interior of the lumbar cistern drainage tube is a drainage cavity for leading out cerebrospinal fluid and / or hydrocephalus. The puncture needle is characterized in that one end of the puncture needle is a puncture tip, a connecting rod is fixed to the other end of the puncture needle and used for being inserted into a drainage cavity of a lumbar cistern drainage tube, the outer diameter of the connecting rod is larger than the inner diameter of the lumbar cistern drainage tube, and a thin film outer cover for wrapping the joint of the connecting rod and the lumbar cistern drainage tube is fixed on the puncture needle at one end where the connecting rod is located. According to the lumbar cistern drainage puncture needle, the lumbar cistern drainage tube is firmly connected with the puncture needle. The joint is in smooth transition through the thin film outer cover, and in the process that the puncture needle is inserted into the subcutaneous part of a patient to build a subcutaneous tunnel, other tissue cannot be scratched, and the lumbar cistern drainage tube and the puncture needle cannot fall off accidentally.

Description

technical field [0001] The invention relates to a lumbar cistern drainage puncture needle capable of establishing a subcutaneous tunnel, more specifically, a lumbar cistern drainage puncture needle capable of establishing a subcutaneous tunnel. Background technique [0002] Lumbar cistern drainage is a method in which one end of a thin drainage tube is inserted into the lumbar cistern, and the other end continuously drains cerebrospinal fluid out of the body. It is mostly used in diseases such as intracranial infection, cerebral hemorrhage, and subarachnoid hemorrhage. It can relieve the symptoms of hydrocephalus, and has the characteristics of less trauma and less side effects. However, because the drainage tube is relatively thin and the drainage route is long, it is very easy to cause infection of the drainage tube from the puncture site, and even cause the infection to retrograde into the cranium, leading to central intracranial infection, resulting in very serious conse...
