Description

  The present invention relates to a cranial cavity catheter device, and more particularly, while maintaining the advantages of a conventional catheter structure that allows drugs and body fluids to be transferred through different paths, while maintaining the catheter outer diameter constant. This facilitates the use of orthopedic devices useful for accurately positioning the catheter in the ventricle, and facilitates tunneling of the back end of the catheter in the bypass space between the skull and the skin. The present invention relates to a catheter device for a cranial cavity, which can be easily performed and has greatly improved the safety of treatment.

  As is well known, intraventricular hematoma treatment directly removed the hematoma together with the cause treatment through craniotomy, which is a neurosurgical operation, but recently developed tomography or brain magnetic resonance using a developed computer Surgery is used to directly insert a catheter, or use a brain orthosis device to place it more safely and accurately, and then remove the hematoma or drain the cerebrospinal fluid.

  Since this operation can be performed within a short time under local anesthesia, it is suitable for patients who have difficulty in general anesthesia. For example, in the case of intracerebral hemorrhage, after measuring the exact location of the intraventricular hematoma by brain tomography and drilling the skull, a catheter can be inserted into the ventricle directly or using a brain orthosis device Drain hematoma out of the cranial cavity. In this case, the state of drainage differs depending on the degree of maturation (solid or liquid) of the hematoma, and the catheter must be drained for a certain period of time (2 days) because it must be drained gradually in small amounts rather than removing the whole hematoma at once. (~ 3 weeks or more), fixed to the head and the residual hematoma will be drained slowly through the catheter.

  In particular, in the case of solid hematoma, a hematoma solubilizing agent such as urokinase is injected through a catheter to dissolve the hematoma and facilitate discharge.

  However, since such a conventional catheter device has a single drainage pipe that is a single fluid passage, if it is necessary to inject a hematoma lysing agent, antibiotics or physiological saline, it is already in the catheter. A substantial amount of hematoma or cerebrospinal fluid to be filled must be re-introduced into the brain and physiological saline for the internal volume of the catheter must be additionally infused, thereby inducing increased brain pressure. In addition, there was a risk of infection due to repeated injections, and there was a disadvantage that the operation was troublesome.

  Therefore, in order to solve such problems, a catheter 12 as shown in FIG. 2 has been developed. FIG. 2 shows Patent Registration No. 0178113.

  More specifically, as shown in FIG. 1, in order to drain and treat the body fluid including hematoma and cerebrospinal fluid in the ventricle 9, the skull 6 vertically above the ventricle 9 is accurately measured. Drill along line A.

  The cranial cavity refers to the space inside the skull 6 including the brain 4, and after puncturing along the A line, the catheter 12 presented in Patent Registration No. 0178113 is recessed into the puncturing hole and the end portion is It is located in the affected area 10, that is, the ventricle 9.

  In this case, the other end portion of the catheter 12 cannot be positioned so that the other end portion is formed immediately above to prevent infection, and the catheter 12 is folded so as to be bent as shown in FIG. The other end portion is bent and passed through a detour space 8 formed by connecting a puncture needle to the other end portion and piercing between the skin 2 and the upper part of the skull 6. It flows out through the perforated part of the skin 2. Such a technique is called subcutaneous tissue tunneling.

  That is, the catheter 12 is not exposed immediately above the perforation of the ventricle 9, but the end of the catheter 12 is exposed at a position bent through the bypass space 8.

  Preferably, the exposed catheter 12 is fixed by a separate fixture 17, which passes through the through-hole 21 formed in the main body 23, and the main body 23 is fixed. It is fixed to the skull and skin through a separate fixing means that passes through the hole 25.

  The catheter 12 has a discharge tube 14 formed in the center for discharging body fluids including hematoma and cerebrospinal fluid to the outside, and a drug transfer tube 18 is formed at one of the outer predetermined portions.

  The drug transfer tube 18 is cut at a predetermined end portion and connected to the drug injection tube 22, and the drug transfer tube 18 and the drug injection tube 22 are firmly and closely connected to each other by a connecting member 24.

  Therefore, the body fluid including hematoma and cerebrospinal fluid that has flowed through the discharge hole 16 in the affected area 10 is discharged to the outside through the discharge tube 14, and a syringe (not shown) is connected to the drug injection tube 22. When a hematoma lysing agent, antibiotic, or physiological saline is injected, the drug is discharged into the drug discharge hole 20 through the drug injection tube 22 and the drug transfer tube 18 and flows into the affected area 10.

  However, in such a procedure for inserting the catheter 12 into the affected area 10, the end of the catheter 12 should be inserted into the ventricle 9 along an accurate path. If it is mistaken, the brain tissue around the path is damaged. Requires skill. In order to prevent this, a brain orthosis device (not shown) is used. For this purpose, the catheter 12 must be configured uniformly without a protrusion on the outside.

  However, since the catheter 12 has a structure in which a drug injection tube 22 is connected to the drug transfer tube 18 and is connected via a separate connecting member 24, the drug injection branched into a Y-shape from the connecting portion. Since the tube 22 protrudes outside the catheter 12, not only can this device be used, but also the tunneling of the rear end of the catheter 12 between the skull 6 and the skin 2 is difficult, making the procedure more difficult and complicated. It was.
