The high frequency transmitting electrode insertion device of the present invention is an apparatus for performing a procedure such as necrosis of specific cells or removal of nerve cells by applying a high frequency to a specific portion of a blood vessel inserted into a blood vessel or the like inside the human body.

3, the high frequency transmitting electrode insertion apparatus according to the first embodiment of the present invention includes an insertion unit 10, a mobile unit 20, a high frequency transmission guide 30, a stimulation unit 60, And a generating unit 40.

That is, the device for inserting a high-frequency transmission electrode of the present invention can be used for various procedures that can apply high-frequency waves only to specific parts of a blood vessel. Specifically, in this embodiment, renal renal artery sympathetic nerve is removed using high- It is explained that the case is applied to the procedure.

The insertion unit 10 includes an outer tube 12 having an opening at the front and a first connector 14 connected to the outer tube 12. [ In other words, a space connected to the opening is formed inside the outer tube 12. A space communicated with the space is also formed in the first connector 14.

The first connector 14 is formed with at least one opening hole 14a into which a guide wire 50, a high frequency applying wire 44 and a moving part 22 to be described later are inserted. That is, the guide wire 50, the high frequency applying wire 44 and the moving part 22 can be inserted into the space through the opening hole 14a.

The mobile unit 20 includes a moving part 22 movably provided inside the outer tube 12 and a second connector 24 coupled to the rear end of the moving part 22. [ That is, when the user moves the second connector 24 in the forward and backward directions while the moving part 22 is inserted into the inside of the outer tube 12, the moving part 22 moves in the front and rear direction .

The high frequency transmission guide 30 is moved along with the movement of the moving part 22 and the opening of the outer tube 12 is moved And is selectively opened.

On the other hand, the mobile unit 20 of the present invention further includes a guide portion 26 coupled to the front end of the moving portion 22. [ The guide portion 26 serves to guide the path of the inside of the human body of the outer tube 12.

The guide portion 26, the moving portion 22, and the second connector 24 are formed with holes communicating with each other. The guide wire 50, which is inserted into the human body through the hole at a later time, passes through the hole.

That is, the guide wire 50 is inserted into the kidney's renal artery (RA) from the outside of the human body. The guide wire 50 exposed to the outside of the human body passes through the holes formed in the guide portion 26, the moving portion 22 and the second connector 24. At this time, since the moving part 22 is inserted into the outer tube 12, the outer tube 12 is guided along the guide wire 50 to the renal artery.

Therefore, the outer tube 12 and the inserted high frequency transmission guide 30 can be introduced more stably and precisely than a procedure in which the high-frequency oscillator directly enters into the renal artery as in the conventional procedure.

The high frequency transmission guide 30 is an apparatus for bringing the electrode 62 into contact with a target point in a state of being inserted into a human body and at least a part thereof is fixed to the moving unit 22 and partly bent to form a protrusion.

The high-frequency transmission guide 30 may be formed in various shapes, and in the present embodiment, it is formed by processing the thin plate-like plate material.

Therefore, the high frequency transmission guide 30 is configured to form a protrusion by the user's manipulation, and the protrusion is selectively opened. The specific shape of the high frequency transmission guide 30 according to the present embodiment will be described later.

On the other hand, the stimulating unit 60 is provided with an electrode 62 at its center, and the electrode 62 is coupled to the protrusion on the high frequency transmission guide 30.

The stimulating unit 60 has a shape similar to that of a band, and is provided at the center of the electrode 62 and disposed at the protruding portion of the high frequency transmission guide 30.

In this embodiment, the stimulating unit 60 mainly comprises an electrode 62, a body part 64 and an engaging part 66, and as shown in Fig. 1, the body part 64 has an electrode 62 are disposed and stacked on the protrusions of the high frequency transmission guide 30. [

The electrode 62 is connected to the high frequency transmission line 44 through which the high frequency transmission line 44 is connected.

More specifically, the body part 64 is formed with a seating groove 62a in which an electrode is seated in the center, and a lower surface of the seating groove 64a is formed so as to communicate with the high frequency application line 44 so as to pass therethrough. The body portion 64 is formed to be larger than the electrode 62 to stably support the electrode 62 and may have a width larger than the width of the high frequency transmission guide 30 in general.

Since the size of the electrode 62 is generally limited, it is preferable that the body portion 64 is formed to be fixed in correspondence with the size of the electrode 62. In this embodiment, The width of the body portion 64 is formed to be larger than the width of the high frequency transmission guide 30 because the body portion 64 is configured to be inserted into the seating groove 64a formed in the body 64. [

The coupling portion 66 extends from both sides of the body portion 64 and is disposed along the longitudinal direction of the high frequency transmission guide 30. The width of the coupling portion 66 is formed to be larger than the width of the high frequency transmission guide 30 so as to surround the high frequency transmission guide 30.

That is, the coupling portion 66 is formed to extend from the body portion 64, and the electrode 62 provided on the body portion 64 can be provided on the projection of the high frequency transmission guide 30. [

In this embodiment, as shown in FIG. 1, the stimulating unit 60 is arranged in such a manner that the electrode 62 is disposed at a position where the protrusion contacts the object point, and then the protrusion of the high frequency transmission guide 30 is wrapped. That is, the high frequency transmission guide 30 does not directly contact the target point by the stimulating unit 60, and the electrode 62 contacts the target point. The high frequency transmission guide 30 is configured such that the electrode 62 selectively contacts the target point As shown in Fig.

Here, the magnetic pole unit 60 is formed of a material that cuts off the high frequency in the remaining portion except for the electrode 62.

The high frequency generating unit 40 applies a high frequency to the electrode 62 coupled to the high frequency transmission guide 30. Specifically, the high frequency generating unit 40 includes a high frequency generating unit 42 and a high frequency applying line 44.

The high-frequency generating unit 42 is generally used for human body surgery using a high-frequency wave, and the description thereof will be omitted. The high frequency transmission line 44 may be connected to the high frequency transmission guide 30 in various forms to apply a high frequency. In the present embodiment, the high frequency transmission line 44 is connected to the electrode 62 through the moving unit 22.

2, the high frequency transmission guide 30 and the moving unit 22 are moved to the outer side of the outer casing in the following manner.

At least one protrusion is formed around the high frequency transmission guide 30 and the high frequency transmission guide 30 is coupled to the moving part 22. [ In addition, the protrusions are formed of a flexible material and can be selectively housed in the outer tube 12 and the moving part 22. That is, the protrusions can be moved to the inside and outside of the outer tube 12 together with the movement of the moving part 22. [

Specifically, in the present embodiment, the high frequency transmission guide 30 is configured such that a plurality of protrusions are disposed along the circumference of the moving part 22 and are formed of a flexible material so as to be selectively foldable.

Accordingly, when the high frequency transmission guide 30 is inserted into the inside of the outer tube 12, the high frequency transmission guide 30 is kept folded along the circumference of the moving portion 22, and the high frequency transmission guide 30 When exposed to the outside of the outer tube 12, the bent portion protrudes.

The high frequency transmission guide 30 is folded along the periphery of the moving part 22 when the high frequency transmission guide 30 is inserted into the inside of the outer tube 12, As shown in FIG.

In addition, a part of the high frequency transmission guide 30 may be configured to be slidable along the moving part 22, and the bent part may be selectively protruded. That is, since the high frequency transmission guide 30 has a flexible material, it can be inserted into the outer tube 12 in various ways.

Next, the construction and manufacturing process of the high frequency transmission guide 30 will be described with reference to FIGS. 4 and 5. FIG.

4 is a view illustrating a process for fabricating a high frequency transmission guide of the high frequency transmitting electrode insertion apparatus according to the first embodiment of the present invention.

The high frequency transmission guide 30 according to the first embodiment of the present invention can be manufactured by processing a material such as plate material.

As shown in the upper part of FIG. 4, a plate material is prepared for manufacturing the high frequency transmission guide 30 of the present embodiment. In this embodiment, the plate material is made of Nitinol (a kind of Ni-Ti alloy) Nitinol) was used.

First, the above-mentioned plate material is processed into a shape as shown in the lower part of Fig. This can be performed by a press process or the like, and the processed plate material specifically includes the fixing portion 32 and the connecting portion 34. [

That is, a plurality of holes formed in the longitudinal direction in the longitudinal direction of the plate member are formed at both ends of the plate member, and a pair of fixing portions 32 are formed at the opposite ends of the pair of fixing portions 32, A plurality of connection portions 34 connecting the pair of fixing portions 32 may be formed.

In addition, a folding line 36 is formed at a predetermined position of the connecting portion 34 together with the above-described processing, so that when the distance between the pair of fixing portions 32 is narrowed, the folding line 36 protrudes, Thereby forming a projection of the delivery guide 30.

Here, at least one folding line 36 is formed on the connecting portion 34, and two folding lines 36 are formed in this embodiment. This will be described later.

Each of the connecting portions 34 generated along with the processing of the plate member is a protruding portion of the high frequency transmission guide 30 and is provided with a magnetic pole unit 60 as shown in each of the connecting portions 34. [

The stimulating unit 60 is configured such that the electrode 62 is positioned on each connecting portion 34 and is coupled to the connecting portion 34 in such a manner as to surround the connecting portion 34. Here, the magnetic pole unit 60 is configured such that the high frequency is cut off in the remaining portion except for the electrode 62.

As shown in the figure, in this step, the plate material processed in the previous step is rolled into a circular shape to be formed into a tube shape elongated in the longitudinal direction.

The plate member having the above-described tubular shape can form the high frequency transmission guide 30 of the high frequency transmitting electrode inserting apparatus according to the first embodiment of the present invention.

5 shows a state in which protrusions are formed by narrowing the space between the fixing portions 32 of the high frequency transmission guide in the high frequency transmitting electrode inserting apparatus according to the first embodiment of the present invention.

5, when the spaced distance between the pair of fixing portions 32 positioned at the front and rear of the high frequency transmission guide 30 formed in the shape of a tube is narrowed, a folding line 36 Are folded, whereby the pair of folding lines 36 can protrude outwardly. Therefore, it forms the protrusion of the high frequency transmission guide 30.

At this time, the fold lines 36 of the plurality of connection portions 34 positioned between the pair of fixing portions 32 may be formed at different positions. Accordingly, each projection can be arranged in a spiral or the like along the periphery of the high frequency transmission guide 30.

Here, it is preferable that the stimulation unit 60 is coupled so that the electrode 62 is positioned between the pair of folding lines 36 formed in the plurality of connection portions 34.

As described above, since the plurality of connection portions 34 are formed to form the protrusion in accordance with the movement of the fixed portion 32, the connection portion 34 serves to support the stimulation unit 60.

Although not shown in the drawing, the high frequency transmission guide 30 further includes a support portion (not shown) for connecting at least one of the plurality of connection portions 34 between neighboring members to connect the high frequency transmission guide 30 to each other .

The supporting portion is further included in the high frequency transmission guide 30 so that when the connecting portion 34 forms the protrusion with reference to the folding line 36, the protrusions connected to each other between the connecting portions 34 are prevented from moving arbitrarily can do.

By providing the high-frequency transmission guide 30 with the high-frequency transmission guide 30 and the magnetic pole unit 60, the high-frequency transmission guide 30 can perform the operation through the high frequency at the target position.

6 is a view illustrating a state where protrusions are formed in accordance with warpage of the high frequency transmission guide in the high frequency transmission electrode insertion apparatus according to the first embodiment of the present invention.

As shown in FIG. 6, in the high-frequency transmission guide 30, the connecting portion 34 is bent according to the movement of the fixing portion 32 to form the protrusion. At this time, the protrusions formed by the connecting portions 34 are formed by protruding between a pair of folding lines 36. The folded portion of the connecting portion 34 by the folding line 36 is formed to be folded in a substantially bent shape.

As described above, since the connecting portion 34 forming the projection is formed to be bent by the folding line 36, it is possible to prevent the blood vessel from being torn during the procedure.

The magnetic pole unit 60 is coupled between the pair of folding lines 36 formed in the connection portion 34 in the high frequency transmission guide 30. Here, the magnetic pole unit 60 is formed of a material in which the high frequency is shielded from the rest except for the electrode 62.

The polymer jacket 39 may further include a polymer jacket 39 disposed at a portion of the high frequency transmission guide 30 according to the present embodiment except for the portion where the stimulating unit 60 is coupled.

The polymer jacket 39 thus formed is formed of a material capable of blocking the high frequency to prevent the high frequency generated in the electrode from being transmitted to a portion other than the target position.

Meanwhile, as shown in the drawing, the high frequency transmission guide 30 is formed to protrude from the coupling portion 62 by the coupling of the stimulating unit 60, and a step is generated. Therefore, it is preferable that the thickness of the polymer jacket 39 is formed to be similar to the thickness of the stimulating unit 60 so as to reduce the occurrence of a step.

In addition, since the polymer jacket 39 is provided as described above, it is possible to prevent the high frequency transmitted to the electrode 62 from diffusing onto the high frequency transmission guide 30.

Meanwhile, the high frequency transmitting electrode inserting apparatus according to the embodiment of the present invention may further include a separate sensor 70 provided in the stimulation unit 60 for sensing the temperature generated by the electrode 62.

Specifically, the detection sensor 70 is disposed adjacent to the electrode 62 formed in the stimulation unit 60 as shown in FIG. 6, and measures a temperature generated as a high frequency is applied to the electrode 62.

Since the sensing unit 70 is provided on the stimulating unit 60 as described above, the heat generated by the electrode 62 in the blood vessel of the user is sensed and the intensity of the high frequency transmitted to the electrode 62 Can be selectively adjusted.

7 is a cross-sectional view showing a state in which the electrode 62 of the stimulating unit 60 is in contact with the blood vessel wall in the high frequency transmitting electrode inserting apparatus according to the first embodiment of the present invention.

The electrode 62 of the stimulating unit 60 is brought into contact with the blood vessel wall by the high frequency transmission guide 30 as shown in Fig. The nerve RP on the inner wall of the renal artery RA can be necrotic due to the high frequency transmitted through the electrode 62.

Here, since the high frequency transmission guide 30 having the stimulating unit 60 has a plurality of bent portions, it is needless to say that the high frequency transmission guide 30 may be applied to various portions at the same time.

8 is a view illustrating a state where the high frequency transmission guide 30 according to the first embodiment of the present invention is further provided with another fixing groove 38 to which the high frequency application line 44 is coupled.

The high frequency transmission line 44 is connected to the high frequency transmission guide 30 so that the high frequency transmission line 44 is connected to the high frequency transmission guide 30, To the stimulating unit (60). The high-frequency generating unit (40)

More specifically, the high-frequency applying line 44 is connected to the electrode 62 through the outer tube 12 along the moving part 22. Here, the high frequency transmission guide 30 is provided with a fixing groove 38 for stable arrangement of the high frequency application line 44 connected to the electrode 62.

The fixing groove 38 is formed along the longitudinal direction inside the connection portion 34 when the high frequency transmission guide is formed by being curled in a cylindrical shape so that a part of the high frequency transmission line 44 is seated.

That is, the high frequency transmission guide 30 is provided with the fixing grooves 38 so that a part of the high frequency transmission line 44 is selectively fixed and fixed to the fixing groove 38 and the high frequency transmission line 44 44 are exposed to the outside so as not to interfere with the procedure.

The configuration of the first embodiment according to the present invention has been described above, and the second embodiment will be described with reference to FIG.

9 is a perspective view illustrating a modified configuration of the high frequency transmission guide in the high frequency transmission electrode insertion apparatus according to the second embodiment of the present invention.

The basic constitution of the high frequency transmitting electrode inserting apparatus according to the present embodiment is similar to that described above, but the high frequency transmitting guide 130 is configured in a different form.

9, one or more protrusions are formed around the high frequency transmission guide 130. The protrusions are installed in the moving part 22, and the distance between the moving part 22 and the outer tube 12 is longer than the distance between the moving part 22 and the outer tube 12. [ And is formed to have a long length. The protrusion is formed of a flexible material and can be accommodated in the inside of the outer tube 12 as the moving part 22 moves. That is, the protrusion can be moved to the inside and outside of the outer tube 12 together with the movement of the moving part 22. [

Meanwhile, the high frequency transmission guide 130 may be formed in various shapes that can be elastically variable. In the case of this embodiment, the high frequency transmission guide 130 includes electrode wires 130a and 130b, at least a part of which is fixed to the moving part 22 and partly bent to form protrusions.

Specifically, in the present embodiment, the high frequency transmission guide 130 includes a first electrode wire 130a and a second electrode wire 130b, which are installed above and below the moving part 22, respectively. The first electrode wire 130a and the second electrode wire 130b are bent a plurality of times to form a plurality of protrusions.

The high frequency transmission guide 130 is formed with protrusions by the first electrode wire 130a and the second electrode wire 130b and the bent portions of the first electrode wire 130a and the second electrode wire 130b The stimulation unit 60 is coupled to the stimulation unit 60. [

More specifically, the electrode 62 is disposed in the outward direction at a bent portion formed in each of the first electrode wire 130a and the second electrode wire 130b, and the high frequency wire 44 is connected to each electrode 62 And transmits a high frequency wave through the electrode 62 to the renal artery RA of the recipient.

In addition, in the present embodiment, it further includes a high frequency blocking part 123 formed to surround the high frequency transmission guide 130 and formed of a high frequency blocking material. An insertion hole 123b is formed in a circumferential surface of the high frequency cut-off portion 123 so that the bent portion of the electrode wires 130a and 130b is inserted and exposed to the outside. A part of the electrode wires 130a and 130b And a fixing member 123a for coupling to the periphery of the moving part 22 is provided.

Specifically, in the present embodiment, a plurality of insertion holes 123b are also formed in the vertical direction so as to correspond to the first and second electrode wires 130a and 130b. The reason why the high frequency cutoff part 123 is formed of the high frequency blocking material is to prevent the high frequency from being transmitted to the area where the procedure is not required.

The first electrode wire 130a and the second electrode wire 130b are folded along the circumference of the high frequency cutoff portion 123 when the high frequency transmission guide 130 is inserted to the inside of the outer tube 12 The bent portion of the first electrode wire 130a and the second electrode wire 130b is inserted into the insertion hole 123b when the high frequency transmission guide 130 is exposed to the outside of the outer tube 12 as shown in FIG. As shown in Fig.

The first electrode wire 130a and the second electrode wire 130b are folded when the high frequency transmission guide 130 is inserted to the inside of the outer tube 12, but alternatively, the electrode wires 130a and 130b May be formed so as to be pressed into the insertion hole 123b by the pressure when inserted into the inside of the outer tube 12. That is, since the electrode wires 130a and 130b have a flexible material, they can be inserted into the outer tube 12 in various ways.

Next, the construction of the high frequency transmission guide according to the third embodiment of the present invention will be described with reference to FIG.

10 is a view showing a moving part 322 and a high frequency transmission guide 330 of the high frequency transmitting electrode inserting device according to the third embodiment of the present invention.

In the third embodiment of the present invention, the guide portion 26, the outer tube 12, and the moving portion 22 are all formed in the same manner as in the second embodiment, but the shape of the high frequency transmission guide 330 is different And a high frequency cutoff unit is not provided.

Specifically, the high frequency transmission guide 330 includes a space forming portion. That is, a plurality of wires 330b intersect to form an inner space and have a net shape. Particularly, some wires 330a of the plurality of wires 330b are provided to form protrusions of the high frequency transmission guide 330 and can be brought into contact with the treatment site at the time of the procedure.

Therefore, the magnetic pole unit 60 is coupled to the wire 330a having the protrusion formed therein to fix the electrode 62.

In the case of the high frequency transmission guide 330 of this type, it is possible to have an elastic force such that it can be expanded in size when exposed to the outside of the outer tube 12.

In addition, other portions of the wire 330a forming the protrusion, except for the engaging position of the stimulating unit 60, may be coated with the high-frequency blocking material, or the above-described polymer jacket 39 may be provided.

Next, a modified embodiment of the stimulation unit according to the embodiment of the present invention will be described with reference to FIG.

As shown in the figure, the overall structure is similar to that described above, but the stimulation unit 60 does not have a separate electrode unlike the above, but includes the body portion 64 and the engaging portion 66.

Specifically, the body portion 64 is formed in a wide plate shape, and is disposed on the protrusions so that one surface of the body portion 64 can contact the inner wall of the blood vessel.

The coupling portion 66 extends from both sides of the body portion 64 and is disposed along the longitudinal direction of the high frequency transmission guide 30. [ The width of the coupling portion 66 is formed to be larger than the width of the high frequency transmission guide 30 so as to surround the high frequency transmission guide 30.

That is, the coupling portion 66 is formed to extend from the body portion 64, and the electrode 62 provided on the body portion 64 can be provided on the projection of the high frequency transmission guide 30. [

The stimulating unit 30 including the coupling portion 66 and the body portion 64 is an electrode and receives a high frequency from the high frequency applying line 44. [ At this time, the high frequency application line 44 is connected to one of the coupling portion 66 and the body portion 64.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
