Ventricle puncture catheter guidance device applied to ventriculoperitoneal shunt}

The present invention relates to a catheter guide device for ventricular puncture applied to ventricular laparotomy, in particular, a curved body spaced apart from the patient's skull during the ventricular puncture process and disposed in a form surrounding the periphery, connected to one end of the curved body, It is disposed in a direction orthogonal to the tangent of the curved body, the catheter guide portion having a guide hole formed through the longitudinal direction therein, connected to the other end of the curved body, is disposed to face the catheter guide portion, the By adopting and applying a simple structure consisting only of a target point support formed on an extension line of the catheter guide part, it is possible to perform simple and accurate ventricular puncture through skull perforation, subject to the operator's experience and skilled surgical ability. , Can perform ventricular puncture quickly, and with a simple structure The present invention relates to a catheter for the ventricle puncture guide device is applied to the ventricle peritoneal shunt which allows to significantly reduce the time, effort and cost for manufacturing.

Ventriculoperitoneal shunting is generally performed to treat hydrocephalus of various causes. It is a surgical procedure in which a puncture of the skull is followed by puncture of the ventricle and tunneling subcutaneously from here to insert the catheter of the shunt system into the abdominal cavity using a separate incision in the abdomen.

In this case, a method of accurately puncturing the ventricle in the deep part of the brain is required in the perforation of the skull, and for this purpose, depending on the operator's experience, puncture toward the center of the brain or using a device such as neuronavigation Is used.

When ventricular celiac surgery is performed using the above-mentioned neuronavigation, there is an advantage that the possibility of accurately puncturing toward the center of the brain is highly secured and the success of the operation is secured, but a problem that the equipment is expensive exists fundamentally.

1 to 3, the catheter guide device 100 for ventricular puncture applied to ventricular laparotomy according to an embodiment of the present invention is connected to a curved body 10 and one end of the curved body 10 It comprises a catheter guide portion 30 and the target point support portion 50 is connected to the other end of the curved body (10).

The curved body 10 is spaced apart from the patient's skull during the ventricular puncture process and arranged in a shape surrounding the periphery. That is, the curved body 10 is formed in a curved structure and is arranged in a form surrounding the patient's skull during the ventricular puncture process, but has a form that can be arranged in a spaced apart state from the skull. As a result, the curved body 10 has a curved shape such as a semi-circle, a semi-ellipse, or a U-shape, and preferably has a concave shape on one side.

Since the curved body 10 constitutes a part of the catheter guide device for surgery, it is preferable to be formed of a material that is not harmful to the human body without contaminating the surroundings, and further, it is formed of a light material to enable smooth operation of the operator. It is preferred.

The catheter guide portion 30 is connected to one end of the curved body 10, and the catheter guide portion 30 is disposed in a direction orthogonal to a tangent line at one end of the curved body 10, and further It is arranged to be placed on the same plane as the curved body 10, and is configured to have a guide hole 31 formed therein in the longitudinal direction.

In this way, the catheter guide portion 30 is connected to one end of the curved body 10, is disposed in a direction orthogonal to the tangent of the curved body 10, a guide hole formed through the longitudinal direction therein (31). Here, the catheter guide portion 30 is disposed in a direction orthogonal to one end of the curved body 10, and is arranged to be placed on the same plane as the curved body 10, the longitudinal direction therein As a guide hole 31 is formed.

The catheter guide part 30 is a tube shape in which the guide hole 31 is formed long inside, and one side thereof protrudes so as to face the target point support part 50 toward the inside of the curved body 10 It is formed, the other side is formed to extend protruding toward the outside of the curved body (10).

The guide hole 31 formed in the longitudinal direction inside the catheter guide portion 30 is a space where the catheter is inserted and guided during ventricular puncture, so that the catheter can be guided stably. Silver is preferably formed to be larger than the diameter of the catheter. Then, the catheter may be moved while being guided through the guide hole 31 in a direction from the other side of the catheter guide portion 30.

Since the catheter guide part 30 also constitutes a part of the catheter guide device for surgery, it is preferable to be formed of a material that is not harmful to the human body without contaminating the surroundings, and further, it is formed of a light material to enable the operator to operate smoothly. It is desirable to be.

In addition, the catheter guide portion 30 is integrally formed on one end of the curved body 10, is formed simultaneously with the curved body 10, or is formed separately from the curved body 10 to be integrated later. It may be formed by combining with.

The target point support portion 50 is connected to the other end of the curved body 10 opposite the catheter guide portion 30, and the target point support portion 50 is necessarily formed to face the catheter guide portion 30 However, it is arranged to be located on the same line. That is, the target point support portion 50 is connected to the other end of the curved body 10, is disposed to face the catheter guide portion 30, necessarily formed on the extension line of the catheter guide portion 30.

As described above, since the target point support portion 50 is disposed to coincide on the same imaginary line as the catheter guide portion 30, it is disposed exactly opposite to the catheter guide portion 30. That is, the target point support portion 50 is formed long on the other end of the curved body 10 so as to be positioned on a virtual straight line without being distorted from the catheter guide portion 30.

As a result, the target point support 50 is also disposed in a direction orthogonal to the tangent line at the other end of the curved body 10, and further arranged to be placed on the same plane as the curved body 10. In this way, the target point support 50 is connected to the other end of the curved body 10, and is arranged in a direction orthogonal to the tangent of the curved body 10.

Since the target point support part 50 is not a part where the catheter is inserted and guided unlike the catheter guide part 30, there is no need to form a long hole in a separate longitudinal direction therein. However, the target point support portion 50 may be manufactured such that a hole is formed therein in the process of being manufactured simultaneously or separately with the catheter guide portion 30 and the curved body 10.

However, the target point support unit 50 may be a part that the operator is constantly holding in the course of ventricular puncture, but because it can maintain a state supported by contact with the patient's skull or skin, it is possible to It is desirable to have a shape and material that does not cause damage, and is formed of a material that does not cause damage, and furthermore, to be stably contact-supported and slip-free. This will be described later.

Since the target point support portion 50 also constitutes a part of the catheter guide device for surgery, it is preferable to be formed of a material that is not harmful to the human body without contaminating the surroundings, and further, it is formed of a light material to enable smooth operation of the operator. It is desirable to be.

In addition, the target point support portion 50 is integrally formed on the other end of the curved body 10, is formed simultaneously with the curved body 10, or is formed separately from the curved body 10 to be integrated later. It may be formed by combining with.

The catheter guide device 100 for ventricular puncture applied to ventricular laparotomy, which is the present invention having the above-described configuration characteristics, is used while performing ventricular puncture, i.

Specifically, the catheter guide portion 30 is spaced apart to face the entry point (EP) corresponding to the skull perforation formed by stenosis in the ventricular puncture process, the target point support portion 50 is the skull perforation is formed It is placed in contact with the target point TP corresponding to any skull portion on the opposite side of the skull 1 portion. At this time, the target point TP is formed at a position to allow the catheter entrance virtual line VL connecting the entry point EP and the target point TP to pass through the ventricle 3.

Referring to FIG. 2 attached to this, the surgeon must perform ventricular puncture in order to perform ventricular celiac surgery on the patient. In order to perform such ventricular puncture, a catheter guide device for ventricular puncture according to the present invention is applied.

The operator creates a perforation of the skull at a specific portion of the skull (eg, near the parieto-occipital (P-O) point) to form an entry point (EP). The operator enters the catheter through this entry point (EP) and proceeds to the ventricle to perform ventricular puncture. Therefore, the operator forms the target point TP in order to form a path through which the catheter previously entered through the entry point EP can accurately enter the ventricle and puncture. The target point TP is not an exact position, but rather a rough position for creating a path for the catheter to perform the ventricular puncture. This will be described later.

In the ventricular puncture process, the operator places the target point support portion 50 in a position or contact-supported state at the target point TP, and the catheter guide portion 30 is an entry point corresponding to the skull perforation (EP ). At this time, the catheter guide portion 30 is preferably maintained by the operator in a somewhat spaced state rather than being supported by the entry point (EP) unlike the target point support (50).

This reflects a realistic problem that it is difficult to manufacture the catheter guide device for ventricular puncture according to the present invention to a size exactly matched to a patient's skull, and further to prevent the problem of contamination or bacterial infection due to contact with the skull perforation. to be. However, the distance between the catheter guide part 30 and the target point support part 50 can be adjusted so that the catheter guide device for ventricular puncture according to the present invention can appropriately correspond to the skull size of each patient, and furthermore, the catheter If it is possible to prevent the occurrence of bacterial infection and contamination by the guide portion 30, the catheter guide portion 30 may be placed in contact with or inserted into the entry point (EP), that is, the skull perforation.

As described above, in the ventricular puncture process, the catheter guide portion 30 corresponds to a portion disposed to face the entry point EP, and the target point support portion 50 is formed with the entry point EP. It corresponds to a portion, that is, a portion that is in contact with and supported by a target point TP formed in any portion of the skull located approximately opposite the portion of the skull where the skull perforation is formed.

In this arrangement, the catheter is inserted and guided through the guide hole 31 of the catheter guide portion 30, enters the entry point (EP), and then continuously inserts the ventricle (3). Arrive in and can puncture the ventricle. Then, as shown in FIG. 3, the catheter may enter the entry point (EP) and puncture the ventricle (3).

The target point TP is an arbitrary part of a skull or skin of a patient that is contact-supported to the target point support part 50, and is a predetermined part, rather than an exact point, depending on the operator's experience and skilled surgical ability. The catheter arrives at the ventricle 3 and corresponds to an approximate location for forming a path sufficient to puncture.

That is, as shown in FIG. 2, as the target point TP, a virtual line VL entering the catheter connecting the entry point EP and the target point TP may pass through the ventricle 30. It is formed in a position to allow. As a result, if a catheter entry virtual line VL that allows the catheter to puncture the ventricle can be formed, the target point TP is irrelevant even if a slight error occurs. That is, even if the target point TP is determined and used in advance, when the target point TP is applied to the skull or skin of a real patient, the catheter performs the ventricular puncture even if there is a slight error in position. It doesn't matter if you can.

On the other hand, in the ventricular puncture process, the catheter is guided through the guide hole 31 of the catheter guide part 30, enters the entry point EP, is inserted until ventricular puncture is made, and the catheter is inserted. Depth is the length of the Mongol measurement corresponding to the distance from the entry point (EP) to the Monro Foramen (Monro Foramen) in the ventricle 30 along the virtual line VL entering the catheter (reference numeral "ML" in FIG. 8). It is preferably).

That is, the catheter may puncture the ventricle by entering through the entry point EP by a predetermined length of the Mongol measurement. The length of the measurement of the Mongol corresponding to the distance from the entry point (EP) to the Monro Foramen in the ventricle 30 along the catheter entry virtual line VL is previously computed tomography and analysis. Can be set.

If this is described, the insertion of the catheter using the catheter guide device for ventricular puncture according to the present invention, as shown in Fig. 7 (a), the part where the fiducial marker (FM) is formed (corresponding to the entry point) It enters through and is inserted into the ventricle.

As such, the catheter is inserted into the oblique direction from the portion where the fiducial marker (FM) is formed to the ventricle. In consideration of such a catheter entry and insertion direction, an optimal catheter entry virtual line (VL) and a target point (TP) are set, and furthermore, the catheter entry and insertion length, that is, the Monrohole measurement length (ML) is accurately measured. In order to do this, computed tomography is also performed to obtain an axial image in a direction similar to the insertion and insertion direction of the catheter, as shown in FIG. 7 (b).

That is, in order to perform a high-precision ventricular puncture using the catheter guide device for ventricular puncture according to the present invention, an axial image by computed tomography is used, but by non-contrast enhanced computed tomography. Obtain the axial image at an angle similar to the direction of entry and insertion of the catheter, not the eye-expansion hole line (orbito-meatal line).

In more detail, as shown in FIG. 8 (a), a patient undergoing ventricular celiac surgery is attached with a reference marker (FM, Fiducial Marker) near the PO point (parieto-occipital point) and non-contrast. Non-contrast enhanced computed tomography is taken. At this time, the photographing is performed so that an axial image can be obtained at an angle similar to the entrance and insertion direction of the catheter, not the eye-expansion hole line (orbito-meatal line).

As described above, among the axial images obtained by non-contrast enhanced computed tomography, an axial image passing through the fiducial marker (FM) is extracted as an analysis target image. 8 (b) shows an axial image passing through the extracted fiducial marker (FM).

In the extracted axial image, the part of the skull in which the fiducial marker (FM) is located is a skull perforation part formed by puncture, and this part is set as an entry point (EP). Starting from the entry point EP, a virtual line penetrating the ventricle 3, that is, a catheter entrance virtual line VL is formed. Then, a target point TP may be set to any part of the skull located on the opposite side of the skull part where the skull perforation is formed. The target point TP corresponds to a position where the catheter entrance virtual line VL passes an arbitrary part of the skull located on the opposite side of the skull part where the skull perforation is formed.

Through the analysis using the extracted axial image, it is possible to form the virtual line VL entering the catheter starting from the entry point EP and penetrating the ventricle 3, through which the target point TP You can set The target point TP is formed at a position allowing the catheter entrance virtual line VL connecting the entry point EP and the target point TP to pass through the ventricle 3.

Then, the depth at which the catheter is inserted is determined. Since the catheter is inserted and inserted along the catheter entrance virtual line VL, the insertion depth of the catheter is from the entry point (EP) to the ventricle (3). , Specifically, it is set as the measurement length (ML) of the Monroe, which corresponds to the distance to the Mongol. That is, the insertion depth of the catheter is a measurement of the length of the Mongol (ML) corresponding to the distance from the entry point (EP) to the Monro's Foramen in the ventricle (30) along the catheter entrance virtual line (VL). It is preferred.

Through such a pre-analysis process, the catheter guide portion 30 is spaced apart to face the entry point EP corresponding to the perforation of the skull formed by stenosis in the ventricular puncture process, and the target point support portion 50 is The cranial perforation may be disposed in contact with the set target point (TP) corresponding to any cranial portion on the opposite side of the cranial portion formed, and further, in the ventricular puncture process, the catheter is a guide hole of the catheter guide unit 30 While being guided through (31), it can be inserted into the entry point (EP) until ventricular puncture is achieved, wherein the insertion depth of the catheter is a length set through analysis in advance, that is, the catheter entry virtual line (VL) ), The measurement of the Mongol corresponding to the distance from the entry point (EP) to Monro's Foramen in the ventricle 30 It corresponds to the length (ML).

According to the catheter guide device 100 for ventricular puncture applied to ventricular laparotomy, which is the present invention having such features and actions, simple and accurate ventricle through skull perforation on the condition of the operator's experience and skilled surgical ability In addition to being able to perform puncture, ventricular puncture can be performed quickly, and a simple structure has the advantage of significantly reducing time, effort and cost for manufacturing.

In addition, according to the present invention, the target point is set in advance using an axial image obtained through computed tomography in the same direction as the catheter entry direction, and the catheter entry virtual connects the entry point and the target point. By setting the line so that the Monong measurement length can be set in advance, the effect of enabling more accurate and precise ventricular puncture occurs.

On the other hand, as described above, the target point support unit 50 maintains a state in contact with the skull or skin of the patient corresponding to the target point TP in the process of ventricular puncture. Therefore, during the ventricular puncture process, the skull or skin of the patient may be damaged by the pressure of the target point support 50, and further, the target point support 50 may be moved or deviated from the skull or skin of the patient. It may or may result in slippage, which may result in poor ventricular punctures and, at worst, a risk to the patient.

To solve this problem, the catheter guide device 100 for ventricular puncture applied to ventricular laparotomy according to the present invention, as shown in Figure 4, the end of the target point support portion 50 (the catheter guide portion It is preferable to further include a buffer contact portion 51 formed on the end portion opposite to (30).

The buffer contact portion 51 is integrally or detachably coupled to the end of the target point support portion 50 and is formed to have a flat surface or a concave surface toward the catheter guide part 30. When the buffer contact portion 51 has a concave surface toward the catheter guide portion 30, the buffer contact portion 51 can be maintained in a more stable contact with the skull or skin of the patient in the process of ventricular puncture. Since it has a surface contact, it is possible to minimize damage.

On the other hand, the buffer contact portion 51 is preferably provided with a projection 53 on the surface (preferably concave) facing the catheter guide portion 30. Since the protrusion 53 is protrudingly formed on the surface of the buffer contact portion 51 (the surface of the patient's skull or the skin), the buffer contact portion 51 is formed in the skull or skin of the patient during ventricular puncture. It can be prevented from slipping off or slipping.

The buffer contact portion 51 and the projection portion 53 is preferably an elastic and soft material, and further, a material that can prevent slipping. That is, the buffer contact portion 51 and the projection 53 is preferably formed of a rubber material such as silicone material or urethane gel.

As the buffer contact part 51 and the protrusion part 53 are adopted and applied, in the process of ventricular puncture, damage to the skull or skin of the patient can be prevented, and the target point support is stably applied to the skull or skin. At the same time as it is mounted, an effect occurs that allows the slip to be maintained in a prevented state.

Meanwhile, the catheter guide device 100 for ventricular puncture applied to ventricular laparotomy according to the present invention described above is uniform in size and may be used for a specific patient (when the skull is too large or too small) in some cases. It can cause problems that cannot be done.

To this end, the catheter guide device 100 for ventricular puncture applied to ventricular laparotomy according to the present invention is provided with a straight body 20 capable of adjusting the length to the curved body 10, as shown in FIG. It is preferably configured. That is, it is preferable that the curved body 10 applied to the present invention is configured to include a straight body portion 20 that is adjustable in length, rather than curved and curved as a whole.

Specifically, the straight body portion 20 included in the curved body 10 has a structure that is separated into two parts. That is, the straight body portion 20 is composed of a first straight body portion 21 and a second straight body portion 23, the first straight body portion 21 and the second straight body portion 23 Are combined in a structure that is inserted into each other.

Specifically, the first straight body portion 21 is integrally connected to the curved body 10 on one side of the curved bodies 10 on both sides separated from each other, and the second straight body portion 23 is separated from each other Among the curved bodies 10 on both sides, it is integrally connected to the curved body 10 on the other side, and the first straight body portion 21 and the second straight body portion 23 are coupled to allow mutual length adjustment. Of course, when the length of the first straight body portion 21 and the second straight body portion 23 are adjusted by sliding through a structure inserted into each other, a structure capable of maintaining a fixed state is added.

For example, a structure in which the first straight body portion 21 is inserted into the second straight body portion 23 or the second straight body portion 23 is inserted into the first straight body portion 21. By adopting and applying, the length of the straight body portion 20 can be adjusted while one side is sliding to the other side, and as a result, as shown in FIG. 6, the catheter guide portion 30 and the target point support portion The distance between 50 can be adjusted. When the straight body portion 20 is adjusted to a specific length, the first straight body portion 21 and the second straight body portion 23 may be stably engaged with each other through screw coupling or bolt tightening. Can be.

As described above, since the distance between the catheter guide part 30 and the target point support part 50 can be adjusted by adopting and applying the straight body part 20 capable of adjusting the length, various skull sizes can be adjusted. Eggplant can be applied to the patient, and further, if only problems such as contamination and bacterial infection are prevented, the catheter guide unit 30 is inserted into and inserted into the entry point (EP), that is, inserted into the skull perforation. Since it can be, it is possible to enter and insert the catheter in a more stable state, and thereby there is an effect that can perform a more precise ventricular puncture.

In addition, since the curved body is provided with a straight body portion that can be adjusted in length, it is possible to appropriately respond to differences or diversity in the length, size, and / or thickness of the skull of the patients, thereby irrespective of the skull size of the patient. The advantage is that it can be applied to perform accurate and precise ventricular puncture.
