Description

Cranial catheter device

The present invention relates to a cranial catheter device, in particular to maintain the advantages of the original catheter structure for transporting drugs and body fluids through different paths, while maintaining the outer diameter of the catheter to a certain size, so as to be easier to use. The end of the catheter is accurately located in the brain positioning instrument on the ventricle, and makes the tunneling of the posterior end of the catheter easier in the detour space between the skull and the skin, making the surgery easier, thereby greatly improving the safety of the cranial cavity. Catheter device.

It is well known that hematoma treatment in the ventricle is treated by neurosurgical craniotomy for radical causes and direct removal of hematoma, but recently, by using a highly developed computer for cross-section or brain magnetic resonance, direct insertion Catheters or the use of brain positioning instruments to find a location more safely and accurately to remove the hematoma or to extract cerebrospinal fluid are more common.

This procedure can be completed in a short period of time under local anesthesia, making it ideal for patients who cannot be treated for general anesthesia. For example, when intraventricular hemorrhage, the exact location of the ventricle hematoma is accurately measured according to brain cross-section photography. After the skull is perforated, the catheter is inserted into the ventricle directly or by using a brain positioning instrument, and the hematoma is discharged to the outside of the cranial cavity. At this time, according to the degree of maturity (solid or liquid) of the hematoma, the form of the discharge is different, and it is better to remove all the hematomas at a time, and it is preferable to gradually discharge them in a small amount, so that the catheter is fixed to the head for a certain period of time. (2 days ~ 3 Weeks or more) Gradually discharge the hematoma through the catheter to the outside of the body.

In particular, in solid hematoma, a hematoma lysing agent such as urokinase is injected through a catheter to dissolve the hematoma to a state of easy discharge and then discharged to the outside of the body.

However, in the conventional catheter device, since it is a structure of only one discharge tube of a single fluid passage, when it is necessary to inject a hematoma lysing agent or an antibiotic or a physiological saline, a fluid such as a hematoma or cerebrospinal fluid which has flowed into the catheter is required. Re-injection into the brain, and additional injection of normal saline equal to the internal volume of the catheter, not only causes an increase in brain pressure, but also has the risk of infection due to repeated injections, which has the disadvantage of cumbersome operation.

In order to solve such a problem, the catheter 12 shown in Fig. 2 was developed. Fig. 2 is a diagram of Korean Patent Registration No. 0178113.

More specifically, as shown in FIG. 1, in order to discharge and treat the body fluid including the hematoma or cerebrospinal fluid in the ventricle 9, the skull 6 vertically above the ventricle 9 is accurately measured and perforated with the A-type.

The cranial cavity refers to the space inside the skull 6 including the brain 4. After the A-type perforation, the catheter 12 is inserted into the perforated hole as shown in Korean Patent Registration No. 0178113, and the end is located at the affected part 10, the ventricle. 9 on.

At this time, the other end portion of the catheter 12 is formed so as to prevent infection from causing the other end portion to be directly above. The catheter 12 should be bent as shown in FIG. 1, so that the puncture needle is connected at the other end. The detour space 8 formed by the perforation between the skin 2 and the upper portion of the skull 6 causes the other end to be bent and flows out through the other hole of the other skin 2 to the outside. This process is called subcutaneous tissue tunneling.

That is, for the ventricle 9, instead of exposing the catheter 12 directly above the perforation, The end of the conduit 12 is exposed through the detour space 8 in a curved position.

Preferably, the exposed catheter 12 is fixed by a further fixing port 17 through which the catheter 12 forms a through hole 21 formed in the body 23, and the body 23 is fixed to the skull by other fixing means passing through the fixing hole 25. On the skin.

A discharge tube 14 for discharging a body fluid including a hematoma or cerebrospinal fluid to the outside of the body is formed in the center of the catheter 12, and a drug delivery tube 18 is formed at a certain outer side thereof.

The drug delivery tube 18 has an end portion that is cut and connected to the drug injection tube 22, and the drug delivery tube 18 and the drug injection tube 22 are tightly joined together due to the connecting material 24.

Therefore, the body fluid including the hematoma or cerebrospinal fluid flowing from the affected part 10 through the discharge hole 16 is discharged to the outside through the discharge tube 14, and if a hematoma solvating agent is injected into the drug injection tube 22 in conjunction with a syringe (not shown). Or an antibiotic or physiological saline is discharged from the drug discharge hole 20 through the drug injection tube 22 and the drug delivery tube 18, and finally flows into the affected part 10.

However, such an operation of inserting the catheter 12 into the affected part 10 is to insert the end thereof into the ventricle 9 in an accurate path, which may injure the brain tissue around the path, requiring highly skilled operation. In order to prevent such an accident, a brain positioning instrument (not shown) is used, and if the instrument is to be used, it is required that the outside of the catheter 12 has no protruding portion and is formed uniformly.

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, and the connecting portion and the drug injection tube 22 branched in a Y shape protrude to the outside of the catheter 12, Therefore, not only can the instrument not be used, but also the tunneling of the rear end of the catheter 12 between the skull 6 and the skin 2 makes the entire operation more complicated and difficult.

The present invention has been made in view of the state of the art, and an object thereof is to provide an outer diameter of a catheter that is kept constant while maintaining the advantages of an existing catheter structure that transports a drug and a body fluid through different routes. The end of the catheter is accurately inserted into the brain positioning instrument at the position of the ventricle, and in the detour space between the skull and the skin, the tunneling of the catheter at the rear end is easier, making the entire procedure simple and greatly improved.
