In addition, the terminology used in the present invention was selected as a general term widely used as possible now, in a specific case will be described using terms arbitrarily selected by the applicant. In such a case, since the meaning is described in the detailed description of the part, it should be understood that it should not be interpreted simply by the name of the term used in the description of the present invention, and the meaning of the term should be interpreted.

In the present invention, the ectopic pregnancy may be made abnormally at a position other than the fallopian tube, but in the present invention, the case of the ectopic pregnancy in the fallopian tube 2 is illustrated in FIG. 1 and FIG. Let's explain.

Figure 1 is an embodiment to which the present invention is applied, shows a state in which the ectopic pregnancy treatment catheter enters the body.

In general, the sperm and the fertilized egg in the fallopian tube bulge of the fallopian tube 4 is separated from the ovary (5) is stably moved to the uterus to form a stable implantation. However, as shown in FIG. 1, when the gestational sac 3 is abnormally implanted in the fallopian tube 2, the fallopian tube may rupture due to the rapid growth of the gestational sac 3. Therefore, the present invention is to provide an ectopic pregnancy treatment catheter that can inject the drug in a safe and efficient manner in the pregnant bag (3) to prevent the growth of the pregnant bag (3).

1, the ectopic pregnancy treatment catheter 10 to which the present invention is applied is inserted into the vagina and inserted into the fallopian tube 2 through the uterine cavity in the uterus 1. In addition, the ectopic pregnancy treatment catheter 10 may invade the gestational sac 3 and inject gestational tissue extinction drug to treat ectopic pregnancy. As another example, the ectopic pregnancy can be effectively treated with only a small amount of the drug by inhaling amniotic fluid in the gestational sac 3 before injecting the gestational tissue extinction drug.

Figure 2 is an embodiment to which the present invention is applied, the enlarged state of the ectopic pregnancy treatment catheter close to the gestational sac (3).

Referring to FIG. 2, the ectopic pregnancy treatment catheter to which the present invention is applied reaches a position capable of accurately penetrating the gestational sac 3 and penetrates the gestational sac 3, and then within the gestational sac 3. Inhalation of amniotic fluid and infusion of the drug into the pregnancy bag 3 can prevent growth of the pregnancy bag 3.

Therefore, the ectopic pregnancy treatment catheter to which the present invention is applied should have a structure capable of penetrating the gestational sac 3 safely by reaching a position capable of accurately penetrating the gestational sac 3. In addition, the ectopic pregnancy catheter should have a structure capable of inhaling amniotic fluid in the gestational sac 3 and injecting a drug into the gestational sac 3. Hereinafter, various embodiments of the ectopic pregnancy catheter to which the present invention is applied will be described.

Figure 3 is an embodiment to which the present invention is applied, showing a schematic perspective view of the ectopic pregnancy treatment catheter, Figures 4 to 6 shows a cross-sectional or cross-sectional perspective view of each part of the ectopic pregnancy treatment catheter.

Referring to FIG. 3, the ectopic pregnancy treatment catheter 10 according to the present invention may include an infiltration part 20, a first flow path part 31, a second flow path part 32, and a connection part 40.

The penetrating portion 20 may be disposed at the front end of the ectopic pregnancy catheter 10 and may have a structure that can be inserted into the body through the cervix. In addition, the penetrating portion 20 may be formed to have a tip that can penetrate the pregnant bag directly. For example, the penetrating portion 20 may be formed to have an inclined surface in one direction as shown in FIGS. 3 and 4. 4 is an enlarged cross-sectional view of the penetrating portion 20. As another example, the penetrating portion 20 may be formed to have a tip at the center of the cross section such as a cone shape (see FIG. 12 or FIG. 17). By implementing the end of the penetrating portion 20 in a pointed shape as described above, the ectopic pregnancy treatment catheter 10 can directly penetrate the gestational sac. In addition, since the penetrating portion 20 has a relatively small size and has a predetermined stiffness and rigidity compared to the size of the pregnant bag, the penetrating part 20 can penetrate the pregnant bag only by a predetermined pressure.

The penetrating portion 20 may have at least one opening on an inclined surface of the penetrating portion 20. For example, in FIGS. 3 and 4, the penetrating portion 20 may have two openings 21 and 22. Referring to FIG. 4, the first opening part 21 is connected to the first flow path part 31 to introduce liquid into the pregnancy bag, and the second opening part 22 is connected to the second flow path part 32. Connected and outflow of liquid from outside into the gestational sac. Here, the liquid in the gestational sac may be amniotic fluid, and the liquid introduced from the outside may be the gestational sac removal drug.

6 is an enlarged perspective view of the connecting portion 40. As illustrated in FIG. 6, the connection part 40 may be disposed at a rear end of the ectopic pregnancy catheter 10 to discharge liquid from the body or to introduce liquid from the outside. The connection part 40 may have at least one opening. For example, as shown in FIGS. 3 and 6, the connection part 40 may have a third open part 41 and a fourth open part 42. The third open part 41 corresponds to the first open part 21 of the penetrating part 20, and the fourth open part 42 corresponds to the second open part of the penetrating part 20. 22). The third opening part 41 is connected to the first flow path part 31 to drain the amniotic fluid in the gestational sac introduced from the first opening part 21. In addition, the fourth opening part 42 is connected to the second flow path part 32 and flows out of the gestational bag removal drug introduced from the outside into the gestational sac through the second opening part 22.

The first flow path part 31 and the second flow path part 32 form a flow path of the liquid flowing through the penetration part 20 or the connection part 40 of the ectopic pregnancy treatment catheter 10. The first flow path part 31 and the second flow path part 32 may have an appropriate shape to smoothly flow the introduced liquid. FIG. 5 is an enlarged cross-sectional view of the ectopic pregnancy treatment catheter including the first flow path part 31 and the second flow path part 32. For example, as illustrated in FIGS. 3 and 5, the first channel part 31 and the second channel part 32 may have an elongated cylindrical shape, but the present invention is not limited thereto.

In addition, the first flow path part 31 may be formed to a diameter to suck the liquid in the pregnant bag, the second flow path part 32 may inject liquid introduced from the outside of the body into the pregnant bag. It can be formed in diameter. For example, referring to FIGS. 3 and 6, the diameter of the third open portion 41 (or the fourth open portion 42) of the connection portion 40 is the first open portion of the penetration portion 20. It may have a value different from the diameter of (21) (or the second open portion 22). When the ectopic pregnancy catheter 10 is inserted into the body, the connection 40 must be connected to an inhalation device or an infusion device outside the body. An example of the suction device or the injection device is a syringe. In this case, the third open portion 41 (or the fourth open portion 42) of the connection portion 40 should have a diameter that can be engaged with the connection portion of the suction device or the injection device. Therefore, the diameter of the third open portion 41 (or the fourth open portion 42) of the connecting portion 40 is the first open portion 21 (or the second open portion) of the penetrating portion 20. It may have a larger value than the diameter of (22)).

In this embodiment, the connecting portion 40 is formed integrally with the ectopic pregnancy treatment catheter 10, but the present invention is not limited thereto. For example, the connection portion 40 may be formed as a separate member and may be provided in a structure that may be combined with the ectopic pregnancy catheter 10.

In another embodiment, the first channel 31 (or the second channel 32) may have the same diameter. Alternatively, the first flow path part 31 (or the second flow path part 32) may have a diameter that gradually decreases or increases in the direction in which the liquid flows. Here, the first flow path part 31 serves to suck the liquid in the pregnancy bag, so that the liquid flows from the first opening part 21 to the third opening part 41. In addition, since the second flow path part 32 serves to inject a gestational bag removal drug, the liquid flows from the fourth opening part 42 to the second opening part 22.

As such, when the ectopic pregnancy treatment catheter 10 is inserted into the body and the infiltration part 20 penetrates into the gestational sac, the third open part 41 of the connection part 40 is connected to an inhalation device so as to be in the gestational sac. Amniotic fluid is inhaled, and the fourth open portion 42 of the connection portion 40 is connected with an infusion device to inject a drug such as methotrexate into the gestational sac. Thus, by discharging the amniotic fluid in the gestational sac out of the body through the first passage 31 to effectively activate the drug when the medicament is injected into the gestational sac. In addition, by injecting the drug directly into the gestational sac via the second flow path 32, it is possible to treat the ectopic pregnancy with only a small amount of the drug without surgical treatment.

The ectopic pregnancy treatment catheter 10 to which the present invention is applied may have the following features to safely reach the gestational sac when inserted into the body. For example, the ectopic pregnancy treatment catheter 10 may have a predetermined stiffness and rigidity to control the direction of progress in order to safely reach the gestational sac after insertion into the gestational sac. It may have some flexibility to prevent it. Alternatively, the ectopic pregnancy catheter 10 may have a bent structure to suit the body structure made by the vaginal cavity, cervix and fallopian tubes. Alternatively, the ectopic pregnancy catheter 10 may have a length reachable to the gestational sac via the vaginal cavity, cervix and fallopian tubes. In addition, the ectopic pregnancy catheter 10 may be formed of a material harmless to the human body, for example, silicon (silicon), polyethylene (polyethylene), latex (latex), polytetrafluoroethylene (PTFE, Polytetra fluoro) It may be made of a material such as ethylene, polyurethane, polyether blockamid copolymer, polyether polyamide polyester multiblock copolymer, or the like.

In another embodiment, the penetrating portion 20 may be formed integrally with the ectopic pregnancy catheter 10, but may be formed in a separate structure. For example, the penetrating portion 20 may be formed in a removable form at the distal end of the ectopic pregnancy catheter 10.

7 and 8 show, in one embodiment to which the present invention is applied, a schematic, partially enlarged perspective view and a cross-sectional view of the distal end of the ectopic pregnancy treatment catheter, the catheter connector, and the inhalation device (or infusion device).

FIG. 14 is a partial cross-sectional view of an ectopic pregnancy treatment catheter having one opening or two openings in a penetrating portion, and FIG. 15 is a perspective view of FIG. 14.

12 to 13, when the ectopic pregnancy treatment catheter enters the body, there is a possibility that liquid or secretion in the body flows into the flow path part 300 through the fifth opening 210. Accordingly, a problem may be attenuated by inhalation of amniotic fluid in the gestational sac or injection of a gestational capsule removal drug. In addition, since the fifth open portion 210 is located at the center of the penetrating portion 200, a problem may be attenuated when the pregnancy bag is punctured.

Therefore, another embodiment of the present invention to describe an ectopic pregnancy treatment catheter comprising a single flow path portion that can solve the above problems.

In FIG. 13, only one opening part 210 of the penetration part 200 connected to the flow path part 300 is illustrated at the tip of the penetration part 200, but the present invention is not limited thereto. That is, as shown in FIGS. 14 and 15, the opening 210a of the ectopic pregnancy catheter 100a is not located at the center of the penetrating portion 200a and is disposed on the outer circumference of the inclined surface of the penetrating portion 200a.

FIG. 16 is a schematic perspective view of an ectopic pregnancy treatment catheter in another embodiment to which the present invention is applied, FIG. 17 is a schematic partial enlarged cross-sectional view of an ectopic pregnancy treatment catheter taken along line II of FIG. 16, and FIG. 18. Is a cross-sectional view of the ectopic pregnancy treatment catheter taken along line II-II of FIG. 17.

In another embodiment of the present invention, the ectopic pregnancy treatment catheter 100b may include a plurality of flow path portions. Likewise, in the present embodiment, only the differences from the above embodiments and the features thereof will be described, and it is obvious to apply the aforementioned various features directly or in combination.

The ectopic pregnancy treatment catheter 100b of FIGS. 16 to 18 includes an infiltration part 200b, a seventh flow part 310b, an eighth flow part 320b, and a connection part 400b.

In FIG. 17, the seventh flow path part 310b and the eighth flow path part 320b have all the characteristics of the first flow path part 31 and the second flow path part 32 described with reference to FIGS. 3 to 6. It is possible. In addition, the penetrating portion 200b also has a curved structure to minimize damage to other organs when entering the body, as shown in FIGS. 12 to 15, and the openings 210b and 220b are formed in the penetrating portion 200b. By having a structure arranged on an inclined surface, it is possible to efficiently carry out gestational sac puncture.

FIG. 18 shows a schematic cross-sectional view taken along line II-II of the ectopic pregnancy treatment catheter 100b of FIG. 17. The ectopic pregnancy treatment catheter 100b may achieve a stable catheter structure by having a symmetrical cross section of the seventh flow path 310b and the eighth flow path 320b.

In another embodiment of the present invention, the cross-sectional shape of the flow path portion of the ectopic pregnancy treatment catheter 100b may be various configurations. 19 to 21 show various embodiments of the cross-sectional shape of the ectopic pregnancy treatment catheter to which the present invention is applied.

In the case of the ectopic pregnancy catheter 100c shown in FIG. 19, the two flow path portions 310c and 320c take a semicircular symmetrical structure but have a catheter support core CR and a catheter support bridge BR therein. It may take the structure. Through such a configuration, deformation of the ectopic pregnancy treatment catheter 100c may not occur due to negative pressure applied to the flow path part in the amniotic fluid inhalation process or drug injection process.

Meanwhile, in the above embodiment, the case where the plurality of flow path sections have a symmetrical shape has been described, but the present invention is not limited thereto. For example, as in the case of the ectopic pregnancy catheter 100d shown in FIG. 20, by asymmetrically forming the sizes of the flow path sections 310d and 320d, the flow path portion is prevented from being blocked and the ectopic pregnancy treatment catheter The position of 100d can be prevented from changing. For example, when the suction amount is larger than the injection amount, the flow path part forming the suction flow path may be blocked, and the pressure in the flow path part may be changed due to intermittent obstruction, thereby changing the position of the ectopic pregnancy treatment catheter 100d. Therefore, a safer procedure can be performed through the asymmetrical structure of the flow path section.

In another embodiment to which the present invention is applied, as shown in FIG. 21, the ectopic pregnancy treatment catheter 100e of the present invention is formed by an integral flow path portion, but is inhaled by forming a flow path membrane 330e in the center of the flow path portion. The flow path portion 310e for use and the flow path portion 320e for injection may be separated. When the drug injection process and the inhalation process are configured to achieve an alternative operation, the flow path membrane 330e of the flexible structure may move left and right within the flow path part, and thus, the inside of the flow path part according to each operation may be performed. By forming the volume change, even when the suction amount is large, it is possible to prevent the risk of blockage of the flow path portion.

FIG. 22 is a schematic partially enlarged perspective view of an orientation control unit of an ectopic pregnancy treatment catheter according to another embodiment to which the present invention is applied, and FIG. 23 is an ectopic pregnancy treatment catheter taken along line III-III of FIG. 22. An enlarged perspective cross-sectional view of the direction controller.

The ectopic pregnancy catheter to which the present invention is applied may include a component for controlling the orientation of the ectopic pregnancy catheter. For example, as shown in FIGS. 22 and 23, the ectopic pregnancy catheter may further include an adjustment knob 25. The adjusting knob 25 may be formed on the outer circumference of the ectopic pregnancy catheter.

The outer diameter Dn of the adjustment knob 25 has a larger value than the outer diameter Do of the ectopic pregnancy catheter, thereby enabling fine and smooth adjustment of the ectopic pregnancy catheter formed of a fine tube. In addition, the control knob 25 may form a control knob protrusion 27 on the outer circumference of the ectopic pregnancy treatment catheter to prevent relative rotation of the control knob 25 and the ectopic pregnancy treatment catheter. have. Accordingly, it is possible to form an adjustment knob projection corresponding portion 26 that is engaged with the adjustment knob projection 27 on the inside of the adjustment knob 25. When the adjustment knob 25 is formed by injection of a material such as silicon, the adjustment knob projection counterpart 26 is accompanied by the adjustment knob projection 27 in a solid process of the adjustment knob 25. It can also be a structure. 23 is only an embodiment of the structure for fixing the adjustment knob 25, the present invention is not limited thereto.

The ectopic pregnancy treatment catheter described with reference to FIGS. 1 to 23 may be implemented in a micro tube type, and thus, it may be difficult to precisely control the direction after insertion and insertion into the body. Therefore, the present invention can use the catheter guide to perform a safer and more accurate procedure using the ectopic pregnancy treatment catheter described in Figures 1 to 23. Accordingly, the present invention can provide an ectopic pregnancy treatment catheter unit having an ectopic pregnancy treatment catheter and a catheter guide.

FIG. 24 is a schematic enlarged perspective view of a catheter guide for guiding the incorporation of an ectopic pregnancy treatment catheter as an embodiment to which the present invention is applied.

The ectopic pregnancy treatment catheter unit 9 to which the present invention is applied may include an ectopic pregnancy treatment catheter 10a and a catheter guide 70. The length of the catheter guide 70 may be shorter than the ectopic pregnancy treatment catheter 10a, and the diameter may be larger than the ectopic pregnancy treatment catheter 10a. This is for the smooth insertion and control of the ectopic pregnancy treatment catheter (10a).

Referring to FIG. 24, the catheter guide 70 may include a guide tip portion 71, a guide penetrating portion 72, and a guide end portion 73. When the catheter guide 70 is inserted into the body, the guide end portion 71 is introduced into the body and the guide end portion 73 remains in the body. One end of the guide through portion 72 is connected to the guide tip 71, and the other end is connected to the guide end 73. The guide penetrating portion 72 may be formed inside the catheter guide 70 to guide the entry path so that the ectopic pregnancy treatment catheter 10a can safely and accurately reach the gestational sac.

In addition, the catheter guide 70 is formed of a body-adaptive structure so that the ectopic pregnancy treatment catheter 10a can reach the gestational sac more safely and accurately. For example, the catheter guide 70 may be formed in a curved structure having a predetermined radius of curvature (ρcm). As shown in FIG. 24, the center line O-O 'of the catheter guide 70 may be formed to have a curved shape with a predetermined radius of curvature ρcm from the straight reference line O-O. This is typically because the fallopian tubes are eccentrically positioned left and right by a predetermined radius of curvature ρcm with respect to the center of the uterus (see FIG. 1 above). Therefore, when the catheter guide 70 is formed in a curved structure suitable for the body structure, the catheter guide 70 can secure a more stable position in the body, and further, the ectopic pregnancy treatment catheter 10a is the catheter guide. Even when entering 70, a more stable and accurate movement path can be secured. In addition, the catheter guide 70 is provided with a predetermined flexibility, so that even if the catheter guide 70 enters the body and contacts other body organs, damage to the body organs can be prevented.

The guide tip 71 may be disposed at the tip of the catheter guide 70 to be inserted into the body through the cervix. The guide end portion 71 includes an opening portion (not shown) at one end thereof, and the opening portion (not shown) is connected to the guide through portion 72. The opening portion (not shown) is formed in an open structure so that the ectopic pregnancy treatment catheter 10a can pass smoothly, and its diameter may be equal to or larger than the diameter of the ectopic pregnancy treatment catheter 10a. However, the present invention is not limited thereto, and the diameter of the opening (not shown) may be smaller than the diameter of the ectopic pregnancy catheter 10a. For example, when the diameter of the opening portion (not shown) is temporarily expandable by a predetermined force, the diameter of the opening portion (not shown) is smaller than the diameter of the ectopic pregnancy treatment catheter 10a. The body material may be prevented from flowing into the catheter guide 70.

The guide tip 71 may have a structure in which one end of the guide tip 71 has a radius smaller than the other end in order to insert the body more smoothly. That is, referring to FIGS. 24 to 26, the guide end portion 71 may be formed to have an inclined surface. In this case, the opening portion (not shown) of the guide tip portion 71 may be located on an inclined surface instead of the center of the guide tip portion 71.

In addition, the guide end portion 71 may be formed in a structure that closes the guide through portion (72). FIG. 25 shows an embodiment in which the present invention is applied and the guide tip 71 is closed by a membrane. The guide tip 71 to which the present invention is applied may be formed in a structure including a membrane 77. Since the guide tip 71 is formed to be closed by the membrane 77, when the catheter guide 70 enters the body, it is possible to prevent the substance from flowing into the catheter guide 70. When the ectopic pregnancy catheter 10a is inserted into the catheter guide 70 and pushed with a predetermined force, the ectopic pregnancy treatment catheter 10a can easily pass through the membrane 77 to penetrate the gestational sac. FIG. 26 illustrates a state in which the ectopic pregnancy catheter 10a penetrates through the membrane 77.

The membrane 77 may be implemented as a thin film having a predetermined thickness. For example, the membrane 77 may be formed of a thin film of 0.1 μm to 0.3 μm, such as polyamide, but the present invention is not limited thereto.

Meanwhile, in FIG. 24, the guide distal end 73 is disposed at the distal end of the catheter guide 70 to serve as an inlet through which the ectopic pregnancy catheter 10a can enter the catheter guide 70. . Therefore, the uterine pregnancy treatment catheter 10a includes an opening (not shown) to smoothly enter, and the opening (not shown) is likewise connected to the guide through portion 72. In addition, when the catheter guide 70 is inserted into the body, the guide distal end 73 may remain outside the body to serve as a handle for adjusting the catheter guide 70 to reach the pregnant sac safely.

As described above, the description of the catheter guide 70 is only an embodiment of the present invention, the present invention is not limited thereto. That is, the various embodiments described with reference to FIGS. 1 through 23 may be applicable to the catheter guide 70.

The ectopic pregnancy catheter described above should be inserted into the body and directly injected into the gestational sac. In addition, the catheter guide should be able to accurately position the catheter guide up to the gestational sac so that the ectopic pregnancy treatment catheter can correctly penetrate the gestational sac. In the above embodiments, the advancing direction of the ectopic pregnancy treatment catheter or the catheter guide using the connection portion 40, 400, 400b of the ectopic pregnancy catheter, the adjustment knob 25, or the distal end portion 73 of the catheter guide. Could be adjusted. Hereinafter, various embodiments in which the direction of progression of the ectopic pregnancy treatment catheter or the catheter guide can be more precisely controlled will be described.

In an embodiment of the invention, the catheter guide may further comprise a component for actuating the end. For example, the catheter guide 70a capable of adjusting the moving direction may include a guide penetrating portion 72a, a direction adjusting penetrating portion 75, and a direction adjusting line 80a.

The direction adjusting through part 75 is spaced apart from the guide through part 72a and is formed therein along the length direction of the catheter guide 70a.

One end of the direction control line 80a is connected to the inner surface of the direction control through part 75 and the other end is exposed to the outside. As shown in FIG. 28, the direction control line fixing part 81 may be disposed at one end of the direction control line 80a. The direction control line fixing part 81 may be disposed in the inner end of the direction control through portion 75 during the formation of the catheter guide 70a. The other end of the direction control line 80a may be freely adjusted by the operator as a free end, and one end of the direction control line 80a may be integrally movable with the front end of the catheter guide 70a. In addition, the direction control line 80a may be formed of a wire of high strength synthetic resin.

The direction adjusting through part 75 may transmit a tensile force through the direction adjusting line 80a by taking a structure spaced apart from the center of the catheter guide 70a at a predetermined interval. At this time, the tip portion of the catheter guide 70a may be redirected in the direction in which the direction control line 80a is located. Since the catheter guide 70a has an entry force, the catheter guide 70a may be smoothly changed only by changing a predetermined direction of the tip portion of the catheter guide 70a.

In the embodiment, the direction control line 80a has a structure disposed inside the catheter guide 70a, but the present invention is not limited thereto.

29 is a schematic perspective view of a modified example of the catheter guide capable of adjusting the moving direction as another embodiment to which the present invention is applied.

As shown in FIG. 29, in the catheter guide 70b to which the present invention is applied, a direction adjusting part 75b may be mounted on the outside of the catheter guide 70b. The direction adjusting part 75b may be spaced apart from the guide through part 72b and disposed at an outer side in the longitudinal direction of the catheter guide 70b. The direction adjusting part 75b may include at least one direction adjusting line fixing part 75-1b, 75-2b, and 76b.

One end of the direction control line 80b is fixed only to the direction control line fixing part 76b and is guided to the lower side through the other direction control line fixing parts 75-1b and 75-2b. As such, the eccentric position of the direction control line 80b may be further increased to form a more smooth direction control structure.

According to another embodiment to which the present invention is applied, the catheter guide may change the direction of the tip of the catheter guide by using an electrical signal.

The direction control line 80c may be formed in the catheter guide 70c.

The direction adjuster 90 may be spaced apart from the guide through part 72c and disposed inside the longitudinal direction of the catheter guide 70c. In addition, the direction controller 90 may include a shape memory alloy. For example, when a predetermined electrical signal is applied through the direction control line 80c, the direction control unit 90 generates heat according to the applied electric signal. The direction control unit 90 implemented as a shape memory alloy is deformed into a predetermined shape according to the heat generation state, so that the distal end portion of the catheter guide 70c can change direction.

In addition, at least one direction adjusting unit 90 may be disposed at the tip of the catheter guide 70c.
