Problems solved by technology

[0016] The catheter 12 is a structure in which the drug delivery tube 18 is connected to the drug injection tube 22 and connected by another connecting material 24. The connecting part and the drug injection tube 22 branched in a Y shape protrude outside the catheter 12, Therefore, not only can this instrument not be used, but also it is difficult to penetrate the tunnel at the rear end of the catheter 12 between the skull 6 and the skin 2, making the whole operation more complicated and difficult

Abstract

Disclosed herein is a catheter apparatus for cranial cavities which exhibits the advantage of a conventional catheter structure in that a medicine and a bodily fluid are transferred along different paths, uniformizes the outer diameter of a catheter to easily use stereotactic equipment, and facilitates tunneling of the rear end of the catheter in a bypass space between the skull and the skin, so as to allow an operation to be simply and easily performed and thus to increase safety in operation. The catheter apparatus is advantageous in that no protrusion is formed on the outer surface of the catheter and thus the end of the catheter may be easily and accurately located in a cerebral ventricle using the stereotactic equipment, the catheter may be easily bent through the bypass space, and the rear end of the catheter may be easily exposed to the outside through a perforated part.

Description

technical field [0001] The invention relates to a cranial cavity catheter device, specifically, while maintaining the advantages of the original catheter structure for transporting drugs and body fluids through different paths, the outer diameter of the catheter is kept at a certain size, so that it is easier to use. The end of the catheter is accurately located on the brain positioning instrument on the ventricle, and it makes it easier to penetrate the tunnel at the rear end of the catheter in the circuitous space between the skull and the skin, making the operation easier and greatly improving the safety of the cranial cavity Catheter device. Background technique [0002] It is well known that in the treatment of intraventricular hematoma, the underlying cause is treated and the hematoma is directly removed by neurosurgery craniotomy, but recently, direct insertion of Surgery to remove a hematoma or drain cerebrospinal fluid is more common, using a catheter or a brain-lo...
