In general, the oocyte released from the ovary is fertilized in the tubal bulge which is located 1/3 of the sperm and fallopian tube, and it is transferred to the uterus stably, so that it is implanted in the uterus and normal pregnancy is accomplished. Pregnancy occurs. That is, an ectopic pregnancy refers to an implantation at an abnormal position of the embryo, and various types of abnormal pregnancy states such as tubal pregnancies, cervical pregnancies, ovarian pregnancies, peritoneal pregnancies, etc. may be formed depending on the implantation position of the embryo. Double tubal pregnancies are high in proportion to approximately 98% of the total ectopic pregnancy rate. These ectopic pregnancies are dangerous because they are not only accompanied by the inheritance of the fetus but also threaten the health of the mother. In the case of tubal pregnancy, the rapid growth of the fertilized egg in the fallopian tubes is accompanied by tubal tear, which is accompanied by a severe aftereffect which makes later pregnancy impossible. For this purpose, conventional medical treatments such as intramuscular injection of methotrexate, which is a type of anticancer drug, and surgical treatment such as laparoscopic or laparotomy were performed.

Hereinafter, embodiments of an ectopic pregnancy treatment catheter and an ectopic pregnancy treatment catheter unit having the same according to the present invention will be described with reference to the drawings. The structure and operation of the present invention described with reference to the drawings are described as an embodiment, and the technical idea, the essential structure and the action of the present invention are not limited by the description.

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

In the present invention, the ectopic pregnancy may be abnormally performed at other positions than the fallopian tube. However, in order to facilitate the description of the present invention, the case of ectopic pregnancy in the fallopian tube 2 as shown in FIG. 1 and FIG. .

FIG. 1 shows an embodiment of the present invention in which an ectopic pregnancy therapy catheter enters the body.

In general, from the ovary 5, the spermatozoa and the fertilized oocyte stably migrate to the uterus in the fallopian tube of the fallopian tube 4 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 be ruptured due to the rapid growth of the gonad. Accordingly, the present invention provides an ectopic pregnancy therapeutic catheter that can inject drugs into the gestational sac 3 safely and efficiently in order to prevent the growth of the gestational sac 3.

Referring to FIG. 1, the ectopic pregnancy therapy 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 of the uterus 1. The ectopic pregnancy therapy catheter 10 can treat the ectopic pregnancy by injecting a pregnancy tissue extinction drug by infiltrating the gestational sac 3. As another example, it is possible to effectively treat ectopic pregnancy with only a small amount of drug by inhaling the amniotic fluid in the gestational sac 3 before injecting the pregnancy tissue extinction drug.

FIG. 2 is an enlarged view of a state in which an ectopic pregnancy therapy catheter is in close proximity to the gestational sac 3, to which the present invention is applied.

2, the ectopic pregnancy treatment catheter to which the present invention is applied reaches a position where the pregnancy bag 3 can be accurately penetrated, penetrates the pregnancy bag 3, It is possible to prevent the growth of the gestational sac 3 by sucking the amniotic fluid and injecting the drug into the gestational sac 3.

Therefore, the ectopic pregnancy treatment catheter to which the present invention is applied should have a structure capable of safely reaching the position where the pregnancy bag 3 can penetrate accurately and penetrate the gestational sac 3. In addition, the ectopic pregnancy treatment catheter should have a structure capable of sucking the amniotic fluid in the gestational sac (3) and injecting the drug into the gestational sac (3). Hereinafter, various embodiments of an ectopic pregnancy catheter to which the present invention is applied will be described.

FIG. 3 is a schematic perspective view of an ectopic pregnancy therapy catheter according to an embodiment of the present invention, and FIGS. 4 to 6 show a cross-sectional view or a cross-sectional perspective view of the catheter of the ectopic pregnancy.

3, the ectopic pregnancy treatment catheter 10 may include a penetration portion 20, a first flow path portion 31, a second flow path portion 32, and a connection portion 40. [

The infiltration part 20 may be disposed at the front end of the ectopic pregnancy therapy catheter 10 and may be inserted into the body through the cervix. The infiltration part 20 may be formed to have a tip that can directly pass through the gestational sac. For example, the penetration portion 20 may be formed to have an inclined surface in one direction as shown in FIGS. 4 is an enlarged view of a cross section of the penetration section 20. As shown in FIG. As another example, the penetration 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 17). The distal end of the infiltration part 20 is shaped like a sharp point so that the ectopic pregnancy therapy catheter 10 can directly pass through the gestational sac. In addition, since the infiltration part 20 has a relatively small size compared to the size of the gestational sac and has a predetermined stiffness, it can pass through the gestational sac only by a predetermined pressure.

The infiltration part 20 may have at least one opening on the inclined surface of the infiltration part 20. For example, in FIG. 3 and FIG. 4, the penetration portion 20 may have two open portions 21 and 22. 4, the first opening 21 is connected to the first flow path portion 31 and flows in the gynecological bag, and the second opening portion 22 is connected to the second flow path portion 32 And flows out from the outside into the gestational sac. Here, the liquid in the gestational sac may be a positive water, and the liquid introduced from the outside may be a gestational sac removal drug.

6 is an enlarged cross-sectional view of the connecting portion 40. As shown in FIG. 6, the connection portion 40 may be disposed at the rear end of the catheter 10 to form a structure for discharging liquid from the body or for introducing liquid from the outside. The connection portion 40 may have at least one opening portion. For example, as shown in FIGS. 3 and 6, the connection portion 40 may have a third opening 41 and a fourth opening 42. The third opening 41 corresponds to the first opening 21 of the infiltration section 20 and the fourth opening 42 corresponds to the second opening of the infiltration section 20 22). The third open part 41 is connected to the first flow path part 31 and flows out the amniotic fluid in the gestation bag introduced from the first opening part 21. [ The fourth opening 42 is connected to the second flow path portion 32 and flows out of the gynecological bag through the second opening 22 into the gynecological bag.

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

In addition, the first flow path portion 31 may be formed to have a diameter capable of sucking the liquid in the gestational sac, and the second flow path portion 32 may be configured to inject liquid introduced from the outside of the body into the gestational sac Diameter. 3 and 6, the diameter of the third opening 41 (or the fourth opening 42) of the connecting portion 40 is larger than the diameter of the first opening 41 of the penetrating portion 20, May have a different value from the diameter of the second opening 21 (or the second opening 22). When the ectopic pregnancy therapy catheter 10 is inserted into the body, the connecting part 40 should be connected to a suction device or an injection device from outside the body. Examples of the suction device or the injection device include a syringe. In this case, the third opening 41 (or the fourth opening 42) of the connecting portion 40 should have a diameter capable of engaging with the connection portion of the suction device or the injection device. The diameter of the third opening 41 (or the fourth opening 42) of the connecting portion 40 is larger than the diameter of the first opening 21 (or the second opening 21) of the penetrating portion 20, (22)). ≪ / RTI >

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

In another embodiment, the first flow path portion 31 (or the second flow path portion 32) may have the same diameter. Alternatively, the first flow path portion 31 (or the second flow path portion 32) may have a diameter that gradually becomes smaller or larger in a direction in which the liquid flows. Here, since the first flow path portion 31 serves to suck the liquid in the gynecological bag, the liquid flows from the first opening portion 21 to the third opening portion 41. Since the second flow path portion 32 injects the gonad removal fluid, the liquid flows from the fourth opening 42 to the second opening 22.

When the catheter 10 is inserted into the body and the penetration portion 20 penetrates the gestational sac, the third opening 41 of the connection portion 40 is connected to the suction device, The fourth opening 42 of the connection portion 40 is connected to the injection device and injects a drug such as methotrexate into the gestational sac. Thus, by discharging the amniotic fluid in the gestational sac through the first channel part 31 to the outside of the gestational sac, it is possible to effectively activate the drug when the drug is injected into the gestational sac. In addition, by injecting the drug directly into the gestational sac through the second flow path portion 32, the ectopic pregnancy can be treated with only a small amount of drug without surgical treatment.

The ectopic pregnancy therapy catheter 10 to which the present invention is applied may have the following characteristics so as to reach the gestational sac safely when inserted into the body. For example, the ectopic pregnancy therapy catheter 10 may have a predetermined stiffness so as to control the direction of movement to reach the gestational sac safely after insertion into the body, and to prevent the body from being damaged by contact in the body And may have a certain degree of flexibility. Alternatively, the ectopic pregnancy treatment catheter 10 may have a structure bent to fit the body structure formed by the vagina, the cervix, and the fallopian tubes. Alternatively, the ectopic pregnancy therapy catheter 10 may have a length reachable to the gestational sac through the vagina, the cervix, and the fallopian tubes. The ectopic pregnancy therapy catheter 10 may be formed of a material harmless to the human body and may be made of a material such as silicone, polyethylene, latex, polytetrafluoroethylene (PTFE) ethylene, polyurethane, polyether blockamid copolymer, polyether polyamide polyester multiblock copolymer, and the like.

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

FIGS. 7 and 8 show a schematic enlarged perspective view and a cross-sectional view of a distal end portion, a catheter connector, and a suction device (or an infusion device) of an ectopic pregnancy treatment catheter according to an embodiment of the present invention.

At this time, the connector fitting 52 may have a diameter connectable to an injection device (or a suction device), for example, the syringe injection part 61 of FIGS. 7 and 8.

The connector body 51 and the connector line portion 55 are arranged on a coaxial line and the center line of the connector line extension portion 57 is connected to an axis line between the connector body 51 and the connector line portion 55 And a connector angle? Indicated by a reference numeral?. As such, the connector angle? Takes an obtuse angle to prevent interference between other catheter connectors that are connected to the connection 40 of the ectopic pregnancy therapy catheter, or between a suction device connected to the catheter connectors, .

8, the outer periphery of the connector line extension 57 may be tapered so as to have an inclined surface at an angle?, Which may cause the third opening 41 of the connection portion 40 (Part 42), but the present invention is not limited thereto. A connector line extending through hole 58 is formed in the connector line extending portion 57 and a connector line through hole 56 is formed in the connector line portion 55. Here, the connector line through-hole 56 connects the connector line extending through-hole 58 having the diameter Dco to the connector connecting hole 52. In addition, the connector line through-hole 56, the connector line extending through-hole 58, and the connector connecting hole 52 may have a gradually changing sectional structure to smoothly cope with a pressure change due to a difference in diameter.

In another embodiment of the present invention, the catheter connector 50 may further comprise a component for securing the connection with an infusion device (or inhalation device) such as a syringe. For example, as shown in FIGS. 7 and 8, the connector fastening part 53 may be provided inside the connector fastening part 52. The connector fastening part 53 may have a protruding structure extending from the inner side surface of the connector fastening port 52 to the center. The fastening corresponding portion 63 having a shape corresponding to the connector fastening portion 53 may be formed on the outer peripheral surface of the syringe inlet 61. Thus, the airtight state can be maintained by forming the interference fit structure of the connector connecting port 52 and the syringe inlet 61, and it is possible to prevent the syringe 60 from being separated from the catheter connector 50 unnecessarily.

This is merely an embodiment of the present invention, but the present invention is not limited thereto. For example, the connector fastening part 53 may have a groove structure, and the fastening corresponding part 63 may have a protruding structure. Or the inner surface of the connector fitting 52 may form a tapered structure to form the fitting structure.

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

12 to 13, there is a possibility that liquid or secretion in the body flows into the channel part 300 through the fifth open part 210 when the ectopic pregnancy treatment catheter enters the body. Therefore, there may be a problem of weakening the effect of the inhalation of amniotic fluid in the gestational sac or the injection of the gestational sac removal drug. In addition, since the fifth opening 210 is located at the center of the penetration part 200, the effect of the puncture of the gestational sac may be weakened.

Therefore, another embodiment of the present invention will describe an ectopic pregnancy treatment catheter including a single flow path portion capable of solving the above problems.

In FIG. 13, the opening 210 of the infiltrating part 200 connected to the flow path 300 is illustrated as being disposed at the tip of the infiltrating part 200, but the present invention is not limited thereto. 14 and 15, the open portion 210a of the ectopic pregnancy therapeutic catheter 100a is not located at the center of the penetrating portion 200a but is disposed on the outer periphery of the inclined surface of the penetrating portion 200a .

FIG. 16 is a schematic perspective view of an ectopic pregnancy treatment catheter according to another embodiment of the present invention, FIG. 17 is a schematic enlarged sectional view of an ectopic pregnancy treatment catheter taken along the line II of FIG. 16, Is a cross-sectional view of an ectopic pregnancy therapeutic catheter taken along line II-II of FIG. 17 above.

In another embodiment of the present invention, the ectopic pregnancy therapy catheter 100b may include a plurality of flow paths. Likewise, in this embodiment, only the differences from the above embodiments and the corresponding features will be described, and it is obvious that the various features described above are directly applied or applied in combination.

The ectopic pregnancy therapeutic catheter 100b shown in FIGS. 16 to 18 includes a penetration portion 200b, a seventh channel portion 310b, an eighth flow portion 320b, and a connection portion 400b.

17, the seventh channel portion 310b and the eighth channel portion 320b are formed by applying the characteristics of the first channel portion 31 and the second channel portion 32 described in FIGS. 3 to 6 It is possible. 12 to 15, the infiltration part 200b has a curved structure in order to minimize damage to other organs when entering the body, and the openings 210b and 220b are formed in the infiltration part 200b It is possible to efficiently perform the gestational sac puncture.

FIG. 18 is a schematic cross-sectional view taken along line II-II of the ectopic pregnancy treatment catheter 100b of FIG. The ectopic pregnancy therapeutic catheter 100b may have a stable catheter structure by having the cross section of the seventh channel portion 310b and the eighth channel portion 320b have a symmetrical shape.

In another embodiment of the present invention, the cross-sectional shape of the channel portion of the ectopic pregnancy therapeutic catheter 100b can be variously configured. 19 to 21 show various embodiments of the cross-sectional shape of an ectopic pregnancy therapeutic catheter to which the present invention is applied.

In the case of the ectopic pregnancy therapeutic catheter 100c shown in Fig. 19, the two flow paths 310c and 320c have a symmetrical structure of a semicircle, but have a catheter supporting core CR and a catheter supporting bridge BR Structure. With this configuration, deformation of the ectopic pregnancy therapeutic catheter 100c can be prevented from occurring due to a negative pressure applied to the channel portion during the amniotic fluid suction process or the drug infusion process.

In the above embodiment, the cross section of the plurality of flow paths has a symmetrical shape, but the present invention is not limited thereto. For example, as in the case of the ectopic pregnancy therapeutic catheter 100d shown in Fig. 20, the flow channel end faces 310d and 320d are formed asymmetrically to prevent the flow path portion from being blocked, It is possible to prevent the position of the movable member 100d from fluctuating. For example, when the suction amount is larger than the injection amount, the flow path portion forming the suction path may be blocked, and the pressure in the flow path portion may be changed by intermittent occlusion, thereby changing the position of the ectopic pregnancy treatment catheter 100d. Therefore, safer operation can be performed through the asymmetrical structure of the cross-section of the flow passage.

When the drug infusion process and the inhalation process are configured to perform alternate operations, the flow path membrane 330e of the flexible structure can be moved in the left and right directions in the flow path portion, By forming the volume change, the risk of clogging of the flow path portion can be prevented even when the suction amount is large.

FIG. 22 is a schematic partial enlarged perspective view of a direction control unit of an ectopic pregnancy therapy catheter according to another embodiment of the present invention, and FIG. 23 is a schematic view of an ectopic pregnancy therapeutic catheter taken along the line III- Sectional view of the direction adjusting unit.

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

The outer diameter Dn of the adjustment handle 25 is greater than the outer diameter Do of the ectopic pregnancy therapy catheter so that the ectopic pregnancy therapy catheter formed of microtubes can be finely and smoothly controlled. The adjustment handle 25 may be formed with an adjustable handle projection 27 on the outer circumference of the ectopic pregnancy therapy catheter to prevent relative rotation between the adjustment handle 25 and the ectopic pregnancy therapy catheter. have. Accordingly, the adjusting knob protrusion corresponding portion 26, which is engaged with the adjusting knob protrusion 27, can be formed on the inside of the adjusting knob 25. When the adjusting knob portion 25 is formed by injection molding using a material such as silicone, the adjusting knob protruding portion corresponding portion 26 is engaged with the adjusting knob projecting portion 27 in the solid process of the adjusting knob portion 25, . ≪ / RTI > 23 corresponds to an embodiment of a structure for fixing the adjustment knob 25, but the present invention is not limited thereto.

The ectopic pregnancy therapy catheter described in FIGS. 1 to 23 is implemented as a micro-tube type, and it may be difficult to precisely control the direction after inserting and inserting the catheter into the body. Accordingly, the catheter guide can be used to perform safer and more accurate procedures using the ectopic pregnancy therapy catheter described in FIGS. 1 to 23. Accordingly, the present invention can provide an ectopic pregnancy therapy catheter unit having an ectopic pregnancy treatment catheter and a catheter guide.

24 is a schematic enlarged perspective view of a catheter guide for guiding the entry of an ectopic pregnancy therapy catheter into the body, according to an embodiment of the present invention.

The ectopic pregnancy therapy 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 length of the catheter 10a and the diameter of the catheter guide 70 may be larger than the diameter of the catheter 10a. This is for smooth insertion and adjustment of the ectopic pregnancy therapy 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 distal end portion 71 flows into the body, and the guide distal end portion 73 remains outside the body. One end of the guide through portion 72 is connected to the guide end portion 71 and the other end is connected to the guide end portion 73. The guide penetration part 72 is formed inside the catheter guide 70 to guide the entry path so that the ectopic pregnancy therapy catheter 10a can reach the gestational sac safely and accurately.

In addition, since the catheter guide 70 is formed in a body adaptive structure, the ectopic pregnancy therapy catheter 10a can reach the gestational sac more safely and accurately. For example, the catheter guide 70 may be formed with a curved structure having a predetermined radius of curvature (rho cm). 24, the center line O-O 'of the catheter guide 70 may be formed to have a bent shape by a predetermined radius of curvature rho cm from a straight line O-O. This is because the fallopian tube is usually positioned eccentrically to the left and right by a predetermined radius of curvature (rho cm) with respect to the center of the uterus (see FIG. 1). Accordingly, when the catheter guide 70 is formed in a bent structure suitable for the body structure, the catheter guide 70 can secure a more stable position in the body, and further, the ectopic pregnancy therapy catheter 10a can be guided by the catheter guide A more stable and precise movement path can be ensured even when the robot enters the robot arm 70. Also, the catheter guide 70 has a predetermined flexibility, so that the catheter guide 70 can be prevented from being damaged even if the catheter guide 70 enters the body and contacts the other body organs.

The guide tip portion 71 may be disposed at the distal end of the catheter guide 70 and may be inserted into the body through the cervix. The guide tip portion 71 includes an opening portion (not shown) at one end thereof, and the opening portion (not shown) is connected to the guide penetrating portion 72. The opening (not shown) may be formed to have an open structure so that the catheter 10a can pass smoothly, and the diameter of the catheter 10a may be equal to or greater than the diameter of the catheter 10a. However, the present invention is not limited to this, and the diameter of the opening (not shown) may be smaller than the diameter of the ectopic pregnancy therapy catheter 10a. For example, when the diameter of the opening (not shown) can be temporarily expanded by a predetermined force, the diameter of the opening (not shown) is made smaller than the diameter of the ectopic pregnancy therapeutic catheter 10a, It is possible to prevent the substance in the body from flowing into the catheter guide 70.

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

Fig. 25 shows a state in which the guide tip portion 71 is closed by the membrane according to an embodiment of the present invention. The guide tip portion 71 to which the present invention is applied may be formed with a structure including a membrane 77. The guide distal end portion 71 is formed in a structure in which the catheter guide 70 is closed by the membrane 77 so that the catheter guide 70 can be prevented from being introduced into the catheter guide 70 when the catheter guide 70 enters the body. When the catheter 10a is inserted into the catheter guide 70 and the catheter 10a is pushed by a predetermined force, the catheter 10a can easily pass through the membrane 77 and infiltrate the gestational sac. FIG. 26 shows a state in which the catheter 10a penetrates through the membrane 77. FIG.

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

24, the guide distal end portion 73 is disposed at the distal end of the catheter guide 70 to serve as an inlet through which the ectopic pregnancy therapy catheter 10a can enter the catheter guide 70 . Accordingly, the catheter 10a includes an opening (not shown) so that the catheter 10a can smoothly enter the catheter 10a. The opening (not shown) is also connected to the guide penetration part 72. In addition, when the catheter guide 70 is inserted into the body, the guide distal end portion 73 is left outside the body, so that the catheter guide 70 can also function as a handle for safely reaching the gestational sac.

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

The ectopic pregnancy treatment catheter described above should be inserted into the body to be able to directly inject the drug through the gestational sac. Also, the catheter guide should likewise be able to accurately position the catheter guide to the gestational sac so that the ectopic pregnancy therapy catheter can accurately pierce the gestational sac.

As shown in FIG. 28, a direction adjusting line fixing portion 81 may be disposed at one end of the direction adjusting line 80a. The direction adjusting line fixing part 81 may be embedded in the inner tip of the direction adjusting penetrating part 75 in the process of forming the catheter guide 70a. The other end of the direction adjusting line 80a is freely adjustable by a practitioner as a free end, and one end of the direction adjusting line 80a can be operated integrally with the distal end of the catheter guide 70a. Further, the direction adjusting line 80a may be formed of a wire of high strength synthetic resin.

The direction adjusting penetration portion 75 may be configured to be spaced apart from the center of the catheter guide 70a by a predetermined distance to transmit the tensile force through the direction adjusting line 80a. At this time, the distal end of the catheter guide 70a can be turned in the direction in which the direction adjusting line 80a is positioned. Since the catheter guide 70a has a positive input, smooth changeover of the catheter guide 70a can be performed only by switching the distal end of the catheter guide 70a in a predetermined direction.

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

The direction adjusting portion 75b may include at least one direction adjusting line fixing portion 75-1b, 75-2b, and 76b.

One end of the direction adjusting line 80b is fixed only to the direction adjusting line fixing portion 76b and is guided to the lower side through the remaining direction adjusting line fixing portions 75-1b and 75-2b. In this way, the eccentric position of the direction adjusting line 80b is further increased, and a more smooth direction adjusting structure can be formed.

According to another embodiment to which the present invention is applied, the catheter guide can switch the direction of the distal end of the catheter guide using an electrical signal.

In this case, the practitioner confirms the length of the ectopic pregnancy therapy catheter 10 necessary for the patient by using the ultrasonic device, and then connects the insertion preventing portion 11 to the ectopic pregnancy therapy catheter 10, It is possible to prevent the risk of the catheter passing over the gestational sac.

As described above, the present invention can provide an ectopic pregnancy treatment catheter, a catheter guide, and an ectopic pregnancy treatment catheter unit including both of them, and these embodiments may include the following features.

For example, by coating a part or all of the surface of the ectopic pregnancy therapy catheter and the catheter guide surface with a material identifiable by the imaging device, the extent to which the ectopic pregnancy therapy catheter and the catheter guide have reached the gestational sac precisely is determined by the imaging device Can be confirmed. For example, the imaging device may be an ultrasound device, an X-ray device, a computed tomography (CT) device, or a magnetic resonance imaging (MRI) device.

As another example, the ectopic pregnancy therapy catheter and catheter guide to which the present invention is applied can be made of a material that can be identified by the imaging device. Therefore, even if the ectopic pregnancy treatment catheter or the catheter guide is inserted into the body without any special identification, it can be identified by the imaging device.

As another example, the outer surface of the catheter guide and the catheter guide to which the present invention is applied may be marked with an identifier that can indicate its length. For example, an identifier that can represent a length may be indicated by a scale, a number, a color, or a material. In addition, the identifier capable of indicating the length may be displayed from the end of the insertion of the ectopic pregnancy treatment catheter and the catheter guide. Or may be displayed once from the outside.

In another example, if the imaging device is not available for treatment of an ectopic pregnancy, first measure the length of the catheter and catheter guide needed for the patient using the imaging device, and then check the scale indicated on the outer surface to determine the ectopic pregnancy It can also be treated.

As another example, by marking the scale on the outer surface of the ectopic pregnancy treatment catheter and the catheter guide, it is possible to confirm how much the ectopic pregnancy treatment catheter or the catheter guide is inserted into the actual body and how much the insertion should be performed. When an ectopic pregnancy therapy catheter and a catheter guide are inserted into the body, it may damage the internal organs of the body and cause discomfort to the patient. Therefore, a safer and more efficient ectopic pregnancy treatment is performed by using the above method can do.

In addition, the catheter and the catheter guide of the ectopic pregnancy treatment catheter according to the present invention described with reference to Figs. 1 to 40 are formed of a flexible material and have a predetermined non-elongation property. Therefore, when the catheter is inserted into the body, It is possible to reach the ectopic pregnancy therapy catheter and the catheter guide precisely to the destination in the body.

In addition, since the ectopic pregnancy therapeutic catheter according to the present invention is formed into a microtubule shape, it can be formed of a rigid material that can be held at a predetermined pressure to prevent a change in shape due to pressure during positive suction or drug injection.

The embodiments described above are only one embodiment, but the present invention is not limited thereto. The various features of the embodiments described in the above Figs. 1 to 40 can be combined with each other. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Substitution, addition, or the like.
