Description

[0001] The present invention relates to a ventricular puncture catheter guidance device applied to a ventriculoperitoneal shunt,

The present invention relates to a catheter guiding device for a ventricular catheter applied to a ventriculoperitoneal shunt, and more particularly, to a curved catheter that is disposed in a manner to surround the periphery of a patient while being separated from a skull of a patient during a ventriculoperitoneal procedure, A catheter guide portion disposed in a direction orthogonal to a tangential line of the curved body and having a guide hole formed therein so as to penetrate in a longitudinal direction thereof; By adopting and adopting a simple structure consisting only of the target point support formed on the extension of the catheter guide portion, it is possible to perform simple and accurate ventricular perforation through the skull puncture under the condition of the operator's experience and skilled surgical ability , Rapid ventricular puncture can be performed, and 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 various causes of hydrocephalus. It is a surgical procedure to puncture the skull and puncture the ventricle, tunneling the subcutaneous tissue from there, and inserting the catheter of the Shunt System into the abdominal cavity using a separate incision in the abdomen.

This procedure requires precise puncture of the ventricle in the deep part of the brain in the perforation of the skull. To do this, it is necessary to use a device such as neuronavigation or puncture toward the center of the brain depending on the operator's experience .

When the ventriculoperitoneal shunt is performed using the above-described neural navigation, there is an advantage that the possibility of puncture accurately toward the center of the brain can be secured and the success of the operation can be secured. However, there is a problem that the equipment is expensive, It is disadvantageous that the burden on the operation cost is increased in the case of the patient who underwent surgery using expensive nerve navigation.

In order to overcome the disadvantage of using neural navigation in this way, a skilled surgeon utilizes a method of performing a puncture operation toward the center of the brain depending on experience. However, if the surgeon experiences such an operation, it may be difficult for the operator to insert the catheter in a desired direction even if he or she is skilled through a lot of experience, and there is a possibility that the course may change during the insertion process. The possibility of puncture accurately toward the center of the region becomes high.

Therefore, if a skilled surgeon carries out surgery based on his or her own experience, a reliable device or method is required to make the operation of the ventriculorrhaphy without complicating the procedure and without prolonging the operation time.

FIG. 2 is a cross- FIG. 3 is a schematic cross-sectional view illustrating a state in which a catheter is inserted using a catheter guiding device for an intraventricular catheter applied to a ventriculoperitoneal shunt according to an embodiment of the present invention. FIG.

1 to 3, an apparatus for guiding a catheter for an intravenous catheter 100 applied to a ventriculoperitoneal shunt according to an embodiment of the present invention includes a curved body 10, And a target point supporter 50 connected to the other end of the curved body 10.

The curved body 10 is spaced apart from the patient's skull in a ventricular pericardial process and is wrapped around the circumference. That is, the curved body 10 is formed in a curved shape and is disposed in a manner to surround the patient's skull in the ventricular puncture process, and can be arranged in a state of being separated from the skull. As a result, it is preferable that the curved body 10 has a curved shape such as a semicircular shape, a semi-elliptical shape, a U-shape, and a concave shape on one side.

Since the curved body 10 constitutes a part of the catheter guiding device for surgery, it is preferable that the curved body 10 is formed of a material which is not harmful to the human body without contaminating the surroundings, and further formed of a light material .

The curved body 10 is connected to the catheter guide portion 30 at one end thereof and the catheter guide portion 30 is disposed in a direction orthogonal to the tangent at one end of the curved body 10, And a guide hole (31) arranged to be placed on the same plane as the curved body (10) and penetrating in the longitudinal direction.

The catheter guide portion 30 is connected to one end of the curved body 10 and is disposed in a direction orthogonal to the tangent of the curved body 10 and has a guide hole (31). The catheter guide part 30 is arranged in a direction orthogonal to one end of the curved body 10 so as to be placed on a virtually same plane as the curved body 10, A guide hole 31 is formed.

The catheter guide portion 30 has a tube shape in which the guide hole 31 is formed long and one side thereof protrudes toward the inside of the curved body 10 toward the target point support portion 50 And the other side thereof is formed so as to protrude and extend toward the outside of the curved body 10.

The guide hole 31 formed in the catheter guide part 30 in the longitudinal direction is a space in which the catheter is inserted and guided during the progression of the ventricular catheterization. Is formed to be finer than the diameter of the catheter. Then, the catheter may be guided through the guide hole 31 in one direction from the other side of the catheter guide part 30.

Since the catheter guide part 30 also constitutes a part of the catheter guiding device for surgery, it is preferable that the catheter guide part 30 is formed of a material which is not harmful to the human body without contaminating the surroundings, and further formed with a light material .

The catheter guide part 30 is integrally formed at one end of the curved body 10 and formed simultaneously with the curved body 10 or formed separately from the curved body 10, As shown in FIG.

The target point support part 50 is connected to the other end of the curved body 10 so as to face the catheter guide part 30. The target point support part 50 is necessarily facing the catheter guide part 30 And are arranged on the same line. That is, the target point support part 50 is connected to the other end of the curved body 10, and is disposed to face the catheter guide part 30, and is necessarily formed on an extension of the catheter guide part 30.

Since the target point support portion 50 is disposed on the same imaginary line as the catheter guide portion 30, the target point support portion 50 is disposed exactly opposite to the catheter guide portion 30. That is, the target point supporter 50 is elongated at the other end of the curved body 10 so that the target point supporter 50 can be positioned on an imaginary straight line without being interlocked with the catheter guide 30.

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

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

However, since the target point supporter 50 can be a portion that the operator is continuously holding during the progression of the ventricular puncture, the target point supporter 50 can maintain the contact state with the skull or the skin of the patient, It is preferable to have a shape and a material that has a shape that does not cause damage, is formed of a material that does not cause damage, and is further stably supported by contact and does not cause slippage. This will be described later.

Since the target point supporter 50 also constitutes a part of the catheter guiding device for surgery, it is preferable that the target point supporter 50 is formed of a material which is not harmful to the human body without contaminating the surroundings, and further formed with a light material .

The target point supporter 50 is integrally formed at the other end of the curved body 10 and is formed simultaneously with the curved body 10 or formed separately from the curved body 10, As shown in FIG.

The ventilator puncture catheter guiding apparatus 100 applied to the ventriculoperitoneal shunt of the present invention having the above-described constitutional features is used while having characteristics relating to a specific arrangement during the progression of the ventricular catheterization, i.e., the ventricular puncture.

Specifically, the catheter guide portion 30 is spaced apart from the entry point EP corresponding to puncturing of the skull formed by the cephalic puncture during the ventricular puncture, and the target point supporter 50 is provided with the catheter guide portion 30, Is placed in contact with a 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 where the catheter entry virtual line VL connecting the entry point EP and the target point TP can pass through the ventricle 3.

Referring to FIG. 2, the surgeon must perform ventriculoperitoneal surgery to perform ventriculoperitoneal shunting for the patient. The ventilator puncture catheter guiding device according to the present invention is applied to perform such ventriculoperitoneal surgery.

The operator forms a skull puncture at a specific portion of the skull (for example, near a parieto-occipital (P-O) point) to form an entry point (EP). The operator enters the catheter through the entry point (EP) and advances to the ventricle to perform the ventricular puncture. Accordingly, the operator forms the target point TP to form a path through which the catheter that has entered through the entry point EP in advance enters the ventricle and punctures correctly. The target point TP is an approximate location for making the path for allowing the catheter to perform the ventricular perforation rather than the correct location. This will be described later.

The operator places the target point support unit 50 in the ventricular puncture position in a position or contact supported state at the target point TP and the catheter guide unit 30 moves the entry point EP corresponding to the skull puncture ). At this time, unlike the target point support unit 50, the catheter guide unit 30 is preferably held by the operator in a state of being slightly distant from the entry point EP.

This reflects a practical problem that it is difficult to manufacture the catheter guide device for an intraventricular catheter according to the present invention in a size exactly matched to the skull of a patient and furthermore to prevent contamination or bacterial infection due to contact with the perforation of the skull to be. However, it is possible to adjust the distance between the catheter guide portion 30 and the target point support portion 50 so that the catheter guide device for an intraventricular catheter according to the present invention can appropriately respond to the size of the skull of each patient, The catheter guide portion 30 may be disposed in contact with or inserted into the entry point EP, that is, the skull puncture, if bacterial infection and contamination by the guide portion 30 can be prevented.

The catheter guide portion 30 corresponds to a portion disposed toward the entry point EP and the target point support portion 50 corresponds to the portion where the entry point EP is formed The portion corresponding to the target point TP formed at an arbitrary portion of the skull, which is located approximately on the opposite side of the skull portion where the skull puncture is formed.

In this arrangement, the catheter is inserted through the guide hole 31 of the catheter guide portion 30 and guided into the entry point EP, and then continuously inserted into the ventricle 3, To reach the ventricle. Then, as shown in FIG. 3, the catheter may enter the entry point EP and be inserted into the ventricle 3 in a punctured state.

The target point TP is an arbitrary part of the skull or skin of the patient that is held in contact with the target point support part 50. The target point TP is determined in advance according to the experience of the operator and the skill of the operator, And corresponds to an approximate position for the catheter to reach the ventricle 3 and form a path that can be punctured.

2, the catheter entry virtual line (VL) connecting the entry point (EP) and the target point (TP) can pass through the ventricle (30) As shown in Fig. As a result, if a catheter entry virtual line (VL) can be formed that allows the catheter to puncture the ventricle, the target point TP may be subject to some error. That is, even when the target point TP is determined and used in advance, when the target point TP is applied to the actual patient's skull or skin, the catheter performs the ventilator puncture even if there is some error regarding the position If you can do it, it is irrelevant.

In the ventriculoperitoneal procedure, the catheter is guided through the guide hole 31 of the catheter guide portion 30 and is inserted into the entry point EP until the ventricular perforation is made, The depth is measured along the catheter entry virtual line VL with a Monro Ball measurement length (indicated as "ML" in FIG. 8) corresponding to the distance from the entry point EP to the Monro Foramen in the ventricle 30, ). ≪ / RTI >

That is, the catheter may enter the entry point EP by a predetermined length of the Monroo measurement length to puncture the ventricle. The length of the Monro Ball measurement corresponding to the distance from the entry point (EP) to the Monro Foramen in the ventricle (30) along the catheter entry virtual line (VL) Can be set.

7 (a), insertion of the catheter using the catheter guiding device for an intravenous catheter according to the present invention is performed by inserting a portion (corresponding to the entry point) where the fiducial marker FM is formed, And then inserted into the ventricles.

Thus, the catheter is inserted into the ventricle in the diagonal direction from the portion forming the fiducial marker (FM). The optimal catheter entry virtual line (VL) and target point (TP) are set in consideration of the entry and insertion directions of the catheter, and furthermore, the entrance and insertion length of the catheter, The computed tomography is also performed to obtain an axial image in the same direction as the insertion and insertion direction of the catheter, as shown in Fig. 7 (b).

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

More specifically, as shown in (a) of FIG. 8, a patient who undergoes surgery for ventriculoperitoneal shunting is attached with a fiducial marker (FM) near a PO point (parieto-occipital point) Non-contrast enhanced computed tomography is taken. At this time, the photographing proceeds not so much as the orbito-meatal line but the axial image at an angle similar to the entrance and insertion direction of the catheter.

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

A portion of the skull in which the reference marker FM is located is formed by puncture surgery in the extracted facial image, and this portion is set as an entry point (EP). A virtual line extending from the entry point EP through the ventricle 3, that is, a catheter entry virtual line VL is formed. Then, a target point TP can be set at an arbitrary portion of the skull located on the opposite side of the skull portion where the skull puncture is formed. The target point TP corresponds to a position where the catheter entry virtual line VL passes through any portion of the skull located on the opposite side of the skull portion where the skull puncture is formed.

Through the analysis using the extracted facial image, it is possible to form the catheter entry virtual line VL starting from the entry point EP and passing through the ventricle 3, Can be set. The target point TP is formed at a position allowing the catheter entry virtual line VL connecting the entry point EP and the target point TP to pass through the ventricle 3.

The depth of insertion of the catheter is then determined since the catheter is advanced and inserted along the catheter entry virtual line VL so that the insertion depth of the catheter is increased from the entry point EP to the ventricle 3 , And specifically, the measured distance (ML) to the Monro Ball measurement corresponding to the distance to the Monro Ball. That is, the depth of insertion of the catheter is measured along the catheter entry virtual line (VL) to the distance from the entry point (EP) to the Monro's Foramen in the ventricle (30) .

Through the pre-analysis process, the catheter guide unit 30 is spaced from the entry point EP corresponding to the puncture of the skull formed by the cephalopexy in the ventricular puncture process, and the target point support unit 50 The catheter may be disposed in contact with the set target point TP corresponding to an arbitrary skull portion of the opposite side of the skull portion formed with the skull bore, The insertion depth of the catheter may be set to a predetermined length through analysis beforehand, that is, the length of the catheter entry virtual line VL ) Corresponding to the distance from the entry point EP to the Monro's Foramen in the ventricle 30, It corresponds to length (ML).

According to the catheter guide device 100 for a ventriculoperitoneal catheter applied to a ventriculoperitoneal shunt of the present invention having the above-described configuration features and operation, it is possible to provide a simple and precise ventricular Not only can the puncture be performed, but also the ventilator puncture can be performed rapidly, and the simple structure makes it possible to greatly reduce the time, effort and cost for manufacturing.

According to the present invention, a target point is set in advance by using an axial image obtained through computer tomography in the same direction as the catheter entry direction, and a catheter entry virtual Line is set so that the measurement length can be set in advance in advance, so that it is possible to perform more accurate and precise ventricular perforation.

Meanwhile, as described above, the target point supporter 50 maintains contact with the skull or skin of the patient corresponding to the target point TP during the ventriculoperitoneal procedure. Accordingly, in the ventricular perforation process, the patient's skull or skin can be damaged by the pressing of the target point support 50, and furthermore, the target point support 50 can be moved or released from the patient's skull or skin It may or may not cause a slip, so ventriculoperitoneal surgery may not proceed smoothly or, at worst, it may pose a risk to the patient.

In order to solve such a problem, as shown in FIG. 4, the apparatus for guiding catheter 100 for a ventriculoperitoneal shunt according to the present invention includes an end portion of the target point supporter 50 (An end portion opposite to the end portion 30).

The cushioning contact portion 51 is integrally or detachably coupled to an end of the target point support portion 50 and is formed to have a flat surface or a concave surface toward the catheter guide portion 30. [ When the cushioning contact portion 51 has a concave surface toward the catheter guide portion 30, the cushioning contact portion 51 can be more stably held in contact with the patient's skull or skin during the ventriculoperitoneal procedure, Since the surface contact is made, damage can be minimized.

Preferably, the cushioning contact portion 51 has a projection 53 on a surface (preferably a concave surface) facing the catheter guide portion 30. The protruding portion 53 protrudes from the surface of the cushioning contact portion 51 (the surface contacting the skull or the skin of the patient), so that the cushioning contact portion 51 is formed in the skull or skin It is possible to prevent it from slipping off or sliding.

It is preferable that the buffer contacting portion 51 and the protruding portion 53 are made of a material which is elastic, soft, and slippery. That is, the buffer contacting portion 51 and the protruding portion 53 are preferably made of a rubber material such as a silicone material or a urethane gel.

With the adoption of the cushioning contact portion 51 and the protrusion 53, damage to the skull or skin of the patient can be prevented in the ventriculoperitoneal procedure, and the target point support can be stably secured to the skull or skin An effect of allowing the slip to be maintained in a state of being prevented from sliding is obtained.

Meanwhile, the catheter guiding device 100 for a ventriculoperitoneal catheter according to the present invention described above can be used for a specific patient The problem can not be solved.

For this purpose, as shown in FIG. 6, the apparatus for guiding catheter 100 for a ventriculoperitoneal catheter according to the present invention includes a linear body 20 having a length adjustable in the curved body 10 . That is, it is preferable that the curved body 10 according to the present invention is constructed not to be curved and curved as a whole but to include a linear body 20 whose length can be adjusted.

Specifically, the linear body portion 20 included in the curved body 10 is divided into two portions. That is, the linear body 20 includes a first linear body 21 and a second linear body 23, and the first linear body 21 and the second linear body 23, Are coupled to each other so as to be inserted into each other.

Specifically, the first linear body 21 is integrally connected to one of the curved bodies 10 of the two curved bodies 10 separated from each other, and the second linear body 23 is separated from the other The first linear body 21 and the second linear body 23 are connected to each other so that the mutual lengths of the curved bodies 10 can be adjusted. Of course, the first linear body 21 and the second linear body 23 are slid through a structure to be inserted into each other, and when the length is adjusted, a structure capable of maintaining the mutually fixed state is added.

For example, when the first linear body 21 is inserted into the second linear body 23 or the second linear body 23 is inserted into the first linear body 21, The length of the linear body portion 20 can be adjusted while sliding one side of the catheter guide portion 30 and the target point support portion 30 as a result, (50). When the straight body part 20 is adjusted to a specific length, the first straight body part 21 and the second straight body part 23 are stably fastened to each other through screwing or bolt tightening .

In this way, since the distance between the catheter guide portion 30 and the target point support portion 50 can be adjusted by adopting the linear body portion 20 having the adjustable length, The catheter guide portion 30 can be inserted into the entry point EP, i.e., inserted into and inserted into the skull puncture, if the catheter guide portion 30 can be applied to the patient, and further, Therefore, the catheter can be introduced and inserted in a more stable state, and thus, the more intricate ventricular perforation can be performed.

In addition, since the curved body is provided with the straight body portion whose length is adjustable, it is possible to appropriately deal with the difference or diversity of the length, the size and / or the thickness of the skulls of the patients, And to perform accurate and precise ventricular perforation.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
