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

The present invention relates to a catheter device for a cranial cavity. Advantages of a conventional catheter structure for transferring a drug and a bodily liquid through different pathways are maintained, and the outer diameter of a catheter is regularly formed, so a brain positioning device which is useful in accurately positioning a catheter end in a brain ventricle can be easily used. A catheter rear side can be easily tunneled in a round space between a skull and skin, so an operation can be conveniently and easily performed and operation safety is remarkably improved. According to the present invention, the outer diameter of a catheter does not have a protruding part, so a catheter end can be accurately and easily disposed in a brain ventricle of an affected area by using a brain poisoning device. Also, a catheter can be easily induced to be bent through a round space between the top of a skull and skin, and a catheter rear end part can be easily discharged to the outside of a cranial cavity through a punching unit.

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...
