Description

Technical Field

[0001] The present invention relates to a vascular intervention treatment device, and more specifically, to a vascular intervention treatment device capable of preventing internal infection caused by contamination of treatment tools inserted into the body during vascular intervention treatment.

Background Art

[0002] Vascular intervention is a minimally invasive surgery aimed at treating vascular diseases and cancer. Mainly under fluoroscopy, a thin catheter with a diameter of several millimeters or less is percutaneously inserted through a blood vessel to the lesion site through the blood vessel to reach the target organ for treatment. Currently, typical treatments for vascular intervention performed worldwide including in Korea are trans-arterial chemoembolization (TACE) for liver cancer, percutaneous transluminal angioplasty, artificial vascular stent placement for aortic diseases, and the like.

[0003] Most blood vessels are composed of a shape with multiple branches and bends. Therefore, in vascular intervention, in order to prevent damage to the blood vessels, an insertion body having various stages of diameters, called a co-axial system of a catheter and a guide wire, is used in an overlapping manner. Also, in vascular intervention treatment, in order to reduce the radiation exposure of the operator, a master-slave type system capable of remotely controlling the treatment tool is used.

[0004] At this time, when treatment tools such as a catheter and a guide wire are directly exposed to the outside, they may be contaminated, and there is a concern about internal infection caused by the contaminated treatment tool during vascular intervention treatment.

[0005] Therefore, there is an urgent need for a solution capable of preventing contamination of treatment tools used in vascular intervention treatment.

[0032] Figure 1 is a diagram illustrating a vascular intervention system in which the vascular intervention device according to the first embodiment of the present invention is used; Figure 2 is a diagram illustrating the vascular intervention device according to the first embodiment of the present invention; Figure 3 is a diagram illustrating the main body of the vascular intervention device according to the first embodiment of the present invention; Figures 4 to 6 are diagrams sequentially showing the process of attaching treatment tools to the ziplock unit of the vascular intervention device according to the first embodiment of the present invention; Figures 7 to 11 are diagrams illustrating the first ziplock member and the second ziplock member of the vascular intervention device according to the first embodiment of the present invention; and Figures 12 to 17 are diagrams illustrating the ziplock unit of the vascular intervention device according to the first embodiment of the present invention.

[0033] As shown in Figure 1, the vascular interventional device 100 according to the first embodiment of the present invention may be applied to a vascular interventional device system consisting of a remote treatment system based on a master-slave device.

[0034] In the aforementioned vascular interventional procedure system, the practitioner remotely controls the procedure via a master device M, and the slave device S performs the procedure on the patient in response to this remote control by the practitioner. This minimizes the environment in which the practitioner is exposed to radiation.

[0035] The vascular interventional device 100 according to the first embodiment of the present invention may be included in a slave device S and remotely controlled by a master device M. In this case, the slave device S may further include a bed 101 and a frame 102.

[0036] The bed 101 can provide a treatment surface on which the patient can lie down so that the patient can receive treatment while lying down. A frame 102 may be movably installed on such a bed 101.

[0037] The vascular interventional device 100 according to the first embodiment of the present invention may be mounted on a frame 102 installed on a bed 101. In this case, the vascular interventional device 100 according to the first embodiment of the present invention may be mounted on the frame 102 so as to be rotatable or translatably movable.

[0038] The vascular interventional device 100 according to the first embodiment of the present invention can rotate the treatment tool in a roll direction or move it forward or backward in order to insert the treatment tool into the body and move it to the target blood vessel. Furthermore, the vascular interventional device 100 according to the first embodiment of the present invention can rotate the treatment tool while simultaneously moving it in a translational motion.

[0039] The practitioner can remotely control the vascular intervention device 100 according to the first embodiment of the present invention via a master device M, and insert the treatment tool operated by the vascular intervention device 100 according to the first embodiment of the present invention into the target blood vessel.

[0040] Here, the surgical instrument may be any one of the following: a catheter inserted into the body, a guidewire drawn into the inside of the catheter, a microconduit drawn into the inside of the catheter, or a microguidewire drawn into the inside of the microconduit.

[0041] On the other hand, the master device M may include a display unit that outputs a user interface UI related to treatment tools and treatment procedures, and an operation unit 103 that generates remote control signals to operate the treatment tools by the operator.

[0042] The master device M provides the vascular interventional device 100 according to the first embodiment of the present invention, which constitutes the slave device S, with remote control signals generated by the operator's operation of the operation unit 103, thereby enabling the operation of the treatment tools driven by these signals remotely. In this way, by allowing the operator to remotely control the vascular interventional device 100, the operator's radiation exposure can be minimized.

[0043] As shown in Figure 2, the vascular interventional device 100 according to the first embodiment of the present invention, which is applied to such a vascular interventional treatment system, may include a main body 110 and a ziplock unit 120.

[0044] The main body portion 110 may extend in one direction. This allows the main body portion 110 to align multiple Ziploc units 120 in the longitudinal direction.

[0045] According to the first embodiment of the present invention, the main body portion 110 may include a rail frame 111, a slide block 112, and a mounting portion.

[0046] The rail frame 111 may be provided in the shape of a bar extending in one direction.

[0047] The slide block 112 may be coupled to the rail frame 111. In this case, the slide block 112 may be coupled to the rail frame 111 so as to be slidable in the longitudinal direction of the rail frame 111.

[0048] When the slide block 112 slides forward on the rail frame 111, the Ziploc unit 120 connected to the slide block 112 can move forward, thereby allowing the surgical tool attached to the Ziploc unit 120 to move toward the target blood vessel while performing a forward translational movement.

[0049] Furthermore, when the slide block 112 slides backward on the rail frame 111, the Ziploc unit 120 connected to the slide block 112 can move backward, thereby allowing the surgical tools attached to the Ziploc unit 120 to be pulled out of the body while moving backward in a translational motion.

[0050] On the other hand, although not shown in the diagram, the slide block 112 may be equipped with a drive device for sliding the slide block 112 relative to the rail frame 111, a drive device for translating the ziplock unit 120 connected to the slide block 112 forward or backward, and a drive device for rolling the treatment tools attached to the ziplock unit 120.

[0051] Multiple mounting sections may be provided along the longitudinal direction of the rail frame 111 and slide block 112. Ziploc units 120 may be detachably attached to these mounting sections.

[0052] As shown in Figure 3, according to the first embodiment of the present invention, the mounting portion may be distinguished into a fixed mounting portion 113 and a movable mounting portion 114.

[0053] The fixed mounting portion 113 may be provided at the longitudinal ends of the rail frame 111 and the slide block 112, respectively.

[0054] According to a first embodiment of the present invention, the first treatment tool 11 may be supported in the longitudinal direction by a Ziploc unit 120 attached to a fixed mounting portion 113 provided at the longitudinal end of the rail frame 111 and by a Ziploc unit 120 attached to a fixed mounting portion 113 provided at the longitudinal end of the slide block 112. The first treatment tool 11 may be, for example, a conduit.

[0055] The movable mounting portion 114 may be provided on at least one side in the longitudinal direction of the slide block 112. The movable mounting portion 114 may be provided so as to be movable in the longitudinal direction of the slide block 112.

[0056] According to a first embodiment of the present invention, the second treatment tool 12 may be supported in the longitudinal direction by a Ziploc unit 120 attached to a fixed mounting portion 113 provided at the longitudinal end of the slide block 112, and by a Ziploc unit 120 attached to a movable mounting portion 114 provided on one longitudinal side of the slide block 112. The second treatment tool 12 may be, for example, a guide wire.

[0057] As a result, the slide block 112 slides forward on the rail frame 111, and the first treatment tool 11 moves forward in translation. When the movable mounting part 114, which is provided on one side of the longitudinal direction of the slide block 112, moves forward and the Ziploc unit 120 attached to it moves in conjunction, the second treatment tool 12 can move forward in translation. In other words, the guide wire can be drawn into the inside of the conduit.

[0058] On the other hand, according to the first embodiment of the present invention, the main body portion 110 may further include a fixing portion 115.

[0059] The fixing portion 115 may be provided on the rear end side in the longitudinal direction of the slide block 112. According to the first embodiment of the present invention, the fixing portion 115 may be provided in a pair.

[0060] A power transmission unit 130 that transmits power to a bobbin unit 140 may be fixed to each of these pair of fixed parts 115. Here, a third treatment tool (not shown) that is attached to a Ziploc unit 120 which is attached to a movable mounting part 114 provided on one side of the longitudinal direction of the slide block 112 may be wound onto the bobbin unit 140.

[0061] As a result, the bobbin unit 140 can wind or unwind the third treatment tool while rotating clockwise or counterclockwise by the power transmission unit 130. This allows the third treatment tool (not shown) to move forward or backward. Here, the third treatment tool (not shown) may be, for example, a microconduit that is drawn into the conduit provided as the first treatment tool 11.

[0062] Multiple Ziploc units 120 may be provided along the longitudinal direction of the main body 110.

[0063] Any one of the multiple Ziploc units 120 may be attached to a fixed mounting portion 113 provided at the longitudinal end of the rail frame 111.

[0064] Furthermore, one of the multiple Ziploc units 120 may be attached to a fixed mounting portion 113 provided at the longitudinal end of the slide block 112.

[0065] Furthermore, one of the multiple Ziploc units 120 may be attached to a movable mounting section 114 provided on one longitudinal side of the slide block 112.

[0066] In this way, multiple Ziploc units 120 may be aligned in the longitudinal direction of the main body 110 by being attached to fixed mounting parts 113 and movable mounting parts 114, which are provided in multiple locations along the longitudinal direction of the rail frame 111 and slide block 112, respectively.

[0067] According to a first embodiment of the present invention, such a Ziploc unit 120 can guide a surgical instrument to be inserted into the body into the human body.

[0068] In this case, the treatment tools may be attached to the Ziploc unit 120 in the vertical direction. Furthermore, the treatment tools attached to the Ziploc unit 120 may be easily separated from the Ziploc unit 120 while being lifted upwards.

[0069] As shown in Figures 4 to 6, according to the first embodiment of the present invention, the first treatment tool 11 and the second treatment tool 12 may be attached vertically to the Ziploc unit 120 with the longitudinal connection via the connector 20.

[0070] For example, the conduit prepared as the first treatment tool 11 and the guide wire prepared as the second treatment tool 12 may be connected longitudinally via the connector 20 and then attached vertically to the Ziploc unit 120.

[0071] In this case, the Ziploc unit 120 may be fitted with a connector 20 to which the first treatment tool 11 is connected substantially to one side in the longitudinal direction and the second treatment tool 12 is connected to the other side in the longitudinal direction.

[0072] The first treatment tool 11, whose longitudinal rear end is connected to the connector 20, may be guided by the Ziploc unit 120 in a manner that allows it to be pulled forward of the Ziploc unit 120.

[0073] Furthermore, the second treatment tool 12, whose longitudinal end is connected to the connector 20, may be guided by the Ziploc unit 120 so that it is pulled out behind the Ziploc unit 120.

[0074] As shown in Figures 7 to 11, according to the first embodiment of the present invention, the Ziploc unit 120 may include a first Ziploc member 121 and a second Ziploc member 122.

[0075] For example, the longitudinal end of the second treatment tool 12 may be connected to a connector 20 that is attached vertically to a Ziploc unit 120 which is attached to a fixed mounting part 113 provided at the longitudinal end of the slide block 112, and the longitudinal rear end of the second treatment tool 12 may be connected to a connector 20 that is attached vertically to a Ziploc unit 120 which is attached to a movable mounting part 114 provided on one longitudinal side of the slide block 112.

[0076] As a result, the second treatment tool 12 is exposed to the outside in the longitudinal direction, and the second treatment tool 12 may become contaminated.

[0077] According to a first embodiment of the present invention, the first Ziploc member 121 and the second Ziploc member 122 may be arranged to surround the outer surface of the treatment tool in the longitudinal direction, gradually joining together as the treatment tool is pulled out in the longitudinal direction, that is, joining in a so-called Ziploc manner.

[0078] This prevents the treatment tools from being exposed to the outside, thus preventing internal infections caused by contamination of the tools.

[0079] According to a first embodiment of the present invention, the first Ziploc member 121 may have a vertically oriented incision 121a on its longitudinal end side so that a surgical tool can be inserted vertically while positioned between it and the second Ziploc member 122. When the incision 121a meets the incision 122a provided on the longitudinal end side of the second Ziploc member 122, a "U" shaped groove can be formed that allows vertical insertion of the surgical tool.

[0080] According to a first embodiment of the present invention, such a first Ziploc member 121 may include a first body 121b, a protrusion 121c, and a first groove 121d.

[0081] The first body 121b forms the external appearance of the first Ziploc member 121. Such a first body 121b may be extended in one direction. In this case, the first body 121b may be extended to a length that can cover the treatment tool in the longitudinal direction. The first body 121b may be made of a flexible material that can be wound onto a first pulley (127a in Figure 14) which will be described later.

[0082] The protrusion 121c may be provided longitudinally on one surface of the first body 121b. Here, the one surface of the first body 121b may be the surface that is joined to the one surface of the second Ziploc member 122 while in close contact with it.

[0083] Such a protrusion 121c may be fitted into the recess 122c of the second Ziploc member 122.

[0084] The first groove 121d may be provided longitudinally at the center of the protrusion 121c. Such a first groove 121d can form a seating hole in which a treatment tool sits longitudinally when it meets the second groove 122d of the second ziplock member 122.

[0085] According to the first embodiment of the present invention, the second ziplock member 122 can surround the treatment tool in the longitudinal direction while being paired with the first ziplock member 121, thereby preventing the treatment tool from being exposed to the outside.

[0086] The longitudinal end of the second Ziploc member 122 may be provided with an incision portion 122a that, when it meets the incision portion 121a provided on the longitudinal end of the first Ziploc member 121, forms a "U" shaped groove that allows the surgical tool to be inserted in the vertical direction.

[0087] Such a second Ziploc member 122 may include a second body 122b, a recessed portion 122c, and a second groove 122d.

[0088] The second body 122b forms the external appearance of the second Ziploc member 122. Such a second body 122b may extend in one direction. In this case, the second body 122b may be extended to a length that can cover the treatment tool in the longitudinal direction. For example, the second body 122b may be provided to be the same length as the first body 121b of the first Ziploc member 121.

[0089] The second body 122b may be made of a flexible material that can be wound onto a second pulley (127b in Figure 14), which will be described later.

[0090] The recessed portion 122c may be provided longitudinally on one surface of the second body 122b that faces one surface of the first body 121b, so that the protruding portion 121c of the first Ziploc member 121 can be fitted into it.

[0091] The second groove 122d may be provided longitudinally at the center of the recessed portion 122c. When such a second groove 122d meets the first groove 121d of the first Ziploc member 121, it can form a seating hole in which a treatment tool can be seated longitudinally.

[0092] According to the first embodiment of the present invention, the interlocking of the protruding portion 121c of the first Ziploc member 121 and the recessed portion 122c of the second Ziploc member 122 allows the first Ziploc member 121 and the second Ziploc member 122 to gradually connect with each other as they are pulled out in the longitudinal direction of the treatment tool, thereby surrounding the outer circumferential surface of the treatment tool in the longitudinal direction.

[0093] On the other hand, as shown in Figures 12 to 17, according to the first embodiment of the present invention, the Ziploc unit 120 may further include a case 123, a guide portion 125, and a Ziploc fixing portion 126.

[0094] The case 123 forms the exterior of the Ziploc unit 120. Inside the case 123, there may be mounting space provided in which a connector 20 is attached, to which one of the treatment tools, for example, a first treatment tool 11, is connected on one longitudinal side and another treatment tool, a second treatment tool 12, is connected on the other longitudinal side.

[0095] In this case, the case 123 may be provided with an opening 123a at its upper end so that the connector 20 can be mounted in the vertical direction.

[0096] According to a first embodiment of the present invention, the Ziploc unit 120 may further include an upper cover 124. The upper cover 124 may be installed on the case 123 in such a manner that it covers the opening 123a after the connector 20 has been mounted vertically to the case 123 through the opening 123a, so as to prevent the connector 20 from detaching upward.

[0097] In this case, the upper cover 124 may be provided with a locking lever 124a that connects to the case 123 so that the upper cover 124 installed on the case 123 does not separate from the case 123. The locking lever 124a can be connected to and disconnected from the case 123, thereby allowing the upper cover 124 to be freely installed on or removed from the case 123.

[0098] According to the first embodiment of the present invention, when the Ziploc unit 120 is attached to a mounting part, for example, a fixed mounting part 113, the drive motor 151 of the drive device provided inside the main body 110 and the drive gear 152 that is axially coupled to the rotation shaft of the drive motor 151 can be inserted into the internal space of the case 123.

[0099] At this time, when the connector 20 is attached to the case 123, the gear 21 provided on the connector 20 can form a single bevel gear while being connected to the drive gear 152. At this time, the gear 21 provided on the connector 20 may be axially coupled to the insertion tube of the connector 20 into which the longitudinal rear end of the first treatment tool 11 is inserted.

[0100] As a result, when the drive motor 151 is activated, the rotational force provided by the drive motor 151 is supplied to the gear 21 via the drive gear 152, thereby causing the gear 21 to rotate, and the first treatment tool 11 to rotate in conjunction with it around its longitudinal axis, i.e., to perform a roll rotation.

[0101] The guide portion 125 may be provided on one side of the case 123. According to the first embodiment of the present invention, the guide portion 125 may be provided on the front side of the case 123.

[0102] Such a guide portion 125 can guide one of the treatment tools, for example, the first treatment tool 11, which is connected to one of the longitudinal sides of the connector 20 attached to the case 123.

[0103] At this time, when the connector 20 is mounted to the case 123 in the vertical direction, the guide portion 125 will face the first treatment tool 11, which is connected to one side of the connector 20 in the longitudinal direction, in the vertical direction.

[0104] As a result, the upper end of the guide portion 125 may be open so that the first treatment tool 11, whose longitudinal rear end is connected to one side of the longitudinal direction of the connector 20, can be inserted in the vertical direction.

[0105] Thus, the open upper end of the guide portion 125 may be connected to the opening 123a provided at the upper end of the case 123.

[0106] According to the first embodiment of the present invention, the guide portion 125 may include a fastening projection 125a.

[0107] The fastening projections 125a may be formed on both sides of the guide portion 125 in the width direction. The Ziploc fixing portions 126 of adjacent Ziploc units 120 are fastened to the guide portion 125 via such fastening projections 125a, which will be explained in more detail below.

[0108] The Ziploc fixing portion 126 may be provided on the other side of the case 123. According to the first embodiment of the present invention, the Ziploc fixing portion 126 may be provided on the rear side of the case 123. In this case, the Ziploc fixing portion 126 may be aligned in one direction with the guide portion 125. In this case, unlike the guide portion 125 which is formed integrally with the case 123, the Ziploc fixing portion 126 is not coupled to the case 123, thereby allowing it to move independently.

[0109] Such a Ziploc-type fixing portion 126 can guide other treatment tools, such as a second treatment tool 12, which are connected to the other longitudinal side of the connector 20 attached to the case 123.

[0110] At this time, when the connector 20 is attached to the case 123 in the vertical direction, the Ziploc fixing part 126 will face the second treatment tool 12, which is connected to the other side of the connector 20 in the longitudinal direction, in the vertical direction.

[0111] As a result, the upper end of the Ziploc fixing portion 126 may be open so that the second treatment tool 12, whose longitudinal tip is connected to the other longitudinal side of the connector 20, can be inserted in the vertical direction.

[0112] Thus, the open upper end of the Ziploc fixing portion 126 may be connected to the opening 123a provided at the upper end of the case 123.

[0113] According to the first embodiment of the present invention, the longitudinal ends of the first Ziploc member 121 and the second Ziploc member 122, which have incisions 121a and 122a, may be fixed to the Ziploc fixing portion 126.

[0114] As a result, the Ziploc fixing portion 126 may move along the longitudinal direction of the treatment tool together with the first Ziploc member 121 and the second Ziploc member 122, and be fastened to the guide portion 125 of other Ziploc units 120 adjacent in the longitudinal direction.

[0115] From another perspective, the Ziploc fixing portion 126 may be fastened to the guide portion 125 of another Ziploc unit 120 adjacent in the longitudinal direction while moving along the longitudinal direction of the treatment tool by pulling the first Ziploc member 121 and the second Ziploc member 122.

[0116] This prevents the surgical instruments from being exposed to the outside, thus potentially preventing internal infection due to contamination of the instruments during vascular intervention procedures.

[0117] Here, the movement of the Ziploc fixing part 126 may be performed by the practitioner.

[0118] Thus, the Ziploc fixing portion 126 may include a first slit 126a and a second slit 126b in order to be fastened to the guide portion 125 of another adjacent Ziploc unit 120.

[0119] The first slit 126a may be formed on one side in the width direction of the Ziploc fixing portion 126. Such a first slit 126a may be connected to the open upper end of the Ziploc fixing portion 126.

[0120] Furthermore, the second slit 126b may be formed on the other side in the width direction of the Ziploc fixing portion 126. Such a second slit 126a may be connected to the open lower end of the Ziploc fixing portion 126.

[0121] According to a first embodiment of the present invention, the Ziploc fixing portion 126 that moves from any one Ziploc unit 120 may be fastened to a guide portion 125 provided on any other Ziploc unit 120 adjacent in the longitudinal direction via the first slit 126a and the second slit 126b, which are coupled to the fastening projection 125a of the guide portion 125 provided on any other Ziploc unit 120 adjacent in the longitudinal direction.

[0122] Using the guide portion 125 as a reference, the fastening projections 125a on both sides of the guide portion 125 pass through the open upper and lower ends of the Ziploc fixing portion 126 provided on other Ziploc units 120 adjacent to each other in the longitudinal direction. Then, one fastening projection 125a may be inserted into the first slit 126a of the Ziploc fixing portion 126, and the other fastening projection 125a may be inserted into the second slit 126b of the Ziploc fixing portion 126. This allows the guide portion 125 and the Ziploc fixing portion 126 of Ziploc units 120 adjacent to each other in the longitudinal direction to be fastened together.

[0123] The practitioner can take the Ziploc fixing part 126 provided on one of the Ziploc units 120 and move it toward the other Ziploc unit 120 adjacent to it in the longitudinal direction, so that the outer surface of the treatment tool is surrounded by the first Ziploc member 121 and the second Ziploc member 122.

[0124] At this time, when the Ziploc fixing portion 126 is located on the tip side of the guide portion 125 provided on the front side of another Ziploc unit 120 adjacent in the longitudinal direction, the operator can rotate the Ziploc fixing portion 126 clockwise, for example. This allows the open upper and lower ends of the Ziploc fixing portion 126 to be aligned with the fastening projections 125a formed on both sides in the width direction of the guide portion 125.

[0125] Thus, the Ziploc fixing portion 126 may be fitted to the outside of the guide portion 125 through one fastening projection 125a that is slidably fastened to the open upper end and the other fastening projection 125a that is slidably fastened to the open lower end.

[0126] In this state, the operator can rotate the Ziploc fixing part 126 counterclockwise. This allows the fastening projection 125a on one side of the guide part 125 to be inserted into the first slit 126a of the Ziploc fixing part 126, and the fastening projection 125a on the other side of the guide part 125 to be inserted into the second slit 126b of the Ziploc fixing part 126.

[0127] This can restrict the longitudinal movement of the Ziploc fixing portion 126. In other words, it can prevent the Ziploc fixing portion 126 from coming off the guide portion 125 of an adjacent Ziploc unit 120.

[0128] As a result, the first ziplock member 121 and the second ziplock member 122 can stably surround the surgical instruments during vascular interventional procedures.

[0129] On the other hand, according to the first embodiment of the present invention, the Ziploc unit 120 may further include a first pulley 127a and a second pulley 127b.

[0130] The first pulley 127a may be located inside the case 123. The first Ziploc member 121 may be wound around such a first pulley 127a. The first Ziploc member 121 may be unwound from the first pulley 127a when the operator grasps and pulls the Ziploc fixing portion 126, which has its longitudinal end fixed.

[0131] The second pulley 127b may be located inside the case 123. The second pulley 127b may be symmetrical to the first pulley 172a. The second Ziploc member 122 may be wound around such a second pulley 127b. The second Ziploc member 122 may be unwound from the second pulley 127b when the operator grasps and pulls the Ziploc fixing portion 126, which has its longitudinal end fixed.

[0132] In this case, a coil spring T may be axially coupled to the rotational shafts of the first pulley 127a and the second pulley 127b. This allows for the automatic retrieval of the pulled-out first Ziploc member 121 and the second Ziploc member 122.

[0133] In other words, when the operator releases the fastening of the Ziploc fixing part 126, which is fastened to the guide part 125 of adjacent Ziploc units 120 in the longitudinal direction, the first Ziploc member 121 and the second Ziploc member 122, which had been unwound, may be wound again onto the first pulley 127a and the second pulley 127b, respectively, by the coil spring (T).

[0134] At this time, the Ziploc fixing portion 126, to which the longitudinal ends of the first Ziploc member 121 and the second Ziploc member 122 are fixed, can be returned to its initial position by winding up the first Ziploc member 121 and the second Ziploc member 122.

[0135] Furthermore, according to the first embodiment of the present invention, the Ziploc unit 120 may further include a coupling guide 128.

[0136] The coupling guider 128 may be provided in the case 123. In this case, the coupling guider 128 may be located between the first pulley 127a and the second pulley 127b.

[0137] The coupling guide 128 can guide the first Ziploc member 121, which is unwound from the first pulley 127a, and the second Ziploc member 122, which is unwound from the second pulley 127b, so that they meet each other in the longitudinal direction and are coupled together.

[0138] As a result, the first Ziploc member 121 and the second Ziploc member 122 can be pulled out of the case 123 while still joined together.

[0139] Before the first Ziploc member 121 and the second Ziploc member 122 are pulled out to the outside, the central part of the connecting guide 128 may have the longitudinal ends of the first Ziploc member 121 and the second Ziploc member 122, which are provided with cuts 121a and 122a, in close contact with each other to form a "U" groove.

[0140] As a result, a treatment tool connected to the other side of the connector 20, such as a second treatment tool 12, can be positioned between the first ziplock member 121 and the second ziplock member 122 while being inserted vertically into the "U" groove.

[0141] Hereinafter, a vascular interventional device according to a second embodiment of the present invention will be described with reference to Figures 18 to 22.

[0142] Figures 18 to 22 are diagrams illustrating the first and second ziplock members of a vascular interventional device according to a second embodiment of the present invention.

[0143] Since the second embodiment of the present invention differs from the first embodiment of the present invention only in the structure of the first and second Ziploc members, a detailed description of the remaining components will be omitted, and their reference numerals will refer to those in the previous figures.

[0144] As shown in Figures 18 to 22, according to a second embodiment of the present invention, the Ziploc unit 120 may include a first Ziploc member 221 and a second Ziploc member 222.

[0145] The first ziplock member 221 and the second ziplock member 222 may be arranged to surround the outer surface of the treatment tool in the longitudinal direction, gradually joining together as the treatment tool is pulled out in the longitudinal direction.

[0146] This prevents the treatment tools from being exposed to the outside, thus potentially preventing internal infections caused by contamination of the treatment tools.

[0147] According to a second embodiment of the present invention, the first Ziploc member 221 may be provided with a vertically oriented incision portion 221a at its longitudinal end, such that a surgical tool can be inserted vertically between it and the second Ziploc member 222. When the incision portion 221a meets the incision portion 222a provided at the longitudinal end of the second Ziploc member 222, a "U" shaped groove can be formed that allows vertical insertion of the surgical tool.

[0148] According to a second embodiment of the present invention, the first Ziploc member 221 may include a first body 221b, a first projection 221c, a first socket portion 221d, and a first groove 221e.

[0149] The first body 221b forms the external appearance of the first Ziploc member 221. Such a first body 221b may be extended in one direction. In this case, the first body 221b may be extended to a length that can cover the treatment tool in the longitudinal direction. The first body 221b may be made of a flexible material that can be wound onto the first pulley 127a.

[0150] The first projection 221c may be provided longitudinally on one side of one surface of the first body 221b, for example, on the upper side of one surface. Such a first projection 221c may be fitted into the second socket portion 222c of the second Ziploc member 222.

[0151] The first socket portion 221d may be provided longitudinally on the other side of one surface of the first body 221b, for example, on the lower side of one surface. The second projection 222d of the second Ziploc member 222 may be fitted into such a first socket portion 221d.

[0152] The first groove 221e may be provided longitudinally on one surface of the first body 221b between the first projection 221c and the first socket portion 221d. When such a first groove 221e meets the second groove 222e of the second ziplock member 222, it can form a seating hole on which a treatment tool can be seated longitudinally.

[0153] According to a second embodiment of the present invention, the second Ziploc member 222 can surround the treatment tool in the longitudinal direction while being paired with the first Ziploc member 221, thereby preventing the treatment tool from being exposed to the outside.

[0154] The longitudinal end of the second Ziploc member 222 may be provided with an incision portion 222a that, when it meets the incision portion 221a provided on the longitudinal end of the first Ziploc member 221, forms a "U" shaped groove that allows the surgical tool to be inserted in the vertical direction.

[0155] Such a second Ziploc member 222 may include a second body 222b, a second socket portion 222c, a second projection 222d, and a second groove 222e.

[0156] The second body 222b forms the external appearance of the second Ziploc member 222. Such a second body 222b may be extended in one direction. In this case, the second body 222b may be extended to a length that can cover the treatment tool in the longitudinal direction. For example, the second body 222b may be provided to the same length as the first body 221b of the first Ziploc member 221.

[0157] The second body 222b may be made of a flexible material that can be wound onto the second pulley 127b.

[0158] The second socket portion 222c may be provided longitudinally on one side of one surface of the second body 222b that faces one surface of the first body 221b, for example, on the upper side of that surface. Such a second socket portion 222c may be provided so as to be able to fit with the first projection portion 221c provided on the upper side of one surface of the first body 221b.

[0159] The second projection 222d may be provided longitudinally on the other side of one surface of the second body 222b, for example, on the lower side of one surface. Such a second projection 222d may be fitted into a first socket portion 221d provided on the lower side of one surface of the first body 221b.

[0160] The second groove 222e may be provided longitudinally on one surface of the second body 222b between the second socket portion 222c and the second projection portion 222d. When such a second groove 222e meets the first groove 221e of the first ziplock member 221, it can form a seating hole on which a treatment tool can be seated longitudinally.

[0161] According to a second embodiment of the present invention, the engagement between the first protrusion 221c of the first Ziploc member 221 and the second socket portion 222c of the second Ziploc member 222, and the engagement between the first socket portion 221d of the first Ziploc member 221 and the second protrusion 222d of the second Ziploc member 222, allows the first Ziploc member 221 and the second Ziploc member 222 to gradually connect with each other as they are pulled out in the longitudinal direction of the treatment tool, thereby surrounding the outer circumferential surface of the treatment tool in the longitudinal direction.

[0162] A vascular interventional device according to a third embodiment of the present invention will be described below with reference to Figures 23 to 25.

[0163] Figures 23 to 25 are diagrams illustrating the first and second ziplock members of a vascular interventional device according to a third embodiment of the present invention.

[0164] Since the third embodiment of the present invention differs from the first embodiment of the present invention only in the structure of the first and second Ziploc members, a detailed description of the remaining components will be omitted, and their reference numerals will refer to those in the previous figures.

[0165] As shown in Figures 23 to 25, according to a third embodiment of the present invention, the Ziploc unit 120 may include a first Ziploc member 321 and a second Ziploc member 322.

[0166] The first ziplock member 321 and the second ziplock member 322 may be arranged to surround the outer surface of the treatment tool in the longitudinal direction, gradually joining together as the treatment tool is pulled out in the longitudinal direction.

[0167] This prevents the treatment tools from being exposed to the outside, potentially preventing internal infections caused by contamination of the tools.

[0168] According to a third embodiment of the present invention, the first Ziploc member 321 may be provided with a vertically oriented incision 321a at its longitudinal end so that a surgical tool can be inserted vertically between it and the second Ziploc member 322. When the incision 321a meets the incision 322a provided at the longitudinal end of the second Ziploc member 322, it can form a "U" shaped groove that allows vertical insertion of the surgical tool.

[0169] According to a third embodiment of the present invention, the first Ziploc member 321 may include a first body 321b and a first groove 321c.

[0170] The first body 321b forms the external appearance of the first Ziploc member 321. Such a first body 321b may be extended in one direction. In this case, the first body 321b may be extended to a length that can cover the treatment tool in the longitudinal direction.

[0171] According to a third embodiment of the present invention, the first body 321b may be made of a rubber magnet.

[0172] The first groove 321c may be provided longitudinally on one surface of the first body 321b. When such a first groove 321c meets the second groove 322c of the second ziplock member 322, it can form a seating hole in which a treatment tool can be seated longitudinally.

[0173] According to a third embodiment of the present invention, the second ziplock member 322 can surround the treatment tool in the longitudinal direction while being paired with the first ziplock member 321, thereby preventing the treatment tool from being exposed to the outside.

[0174] The longitudinal end of the second Ziploc member 322 may be provided with an incision portion 322a that, when it meets the incision portion 321a provided on the longitudinal end of the first Ziploc member 321, forms a "U" shaped groove that allows for vertical insertion of the surgical tool.

[0175] Such a second Ziploc member 322 may include a second body 322b and a second groove 322c.

[0176] The second body 322b forms the external appearance of the second Ziploc member 322. Such a second body 322b may extend in one direction. In this case, the second body 322b may be extended to a length that can cover the treatment tool in the longitudinal direction. For example, the second body 322b may be provided to the same length as the first body 321b of the first Ziploc member 321.

[0177] According to a third embodiment of the present invention, the second body 322b may be made of a rubber magnet. In this case, the faces of the first body 321b of the first Ziploc member 321 and the second body 322b of the second Ziploc member 322, which are made of rubber magnets, may have opposite polarities.

[0178] The second groove 322c may be provided longitudinally on one surface of the second body 322b that faces one surface of the first body 321b. When such a second groove 322c meets the first groove 321c of the first ziplock member 321, it can form a seating hole on which a treatment tool can be seated longitudinally.

[0179] According to a third embodiment of the present invention, the magnetic coupling between the first body 321b of the first ziplock member 321 and the second body 322b of the second ziplock member 322 allows the first ziplock member 321 and the second ziplock member 322 to gradually connect with each other as the treatment tool is pulled out in the longitudinal direction, thereby surrounding the outer circumferential surface of the treatment tool in the longitudinal direction.

[0180] Hereinafter, a vascular interventional device according to a fourth embodiment of the present invention will be described with reference to Figures 26 to 28.

[0181] Figures 26 to 28 are diagrams illustrating the first and second ziplock members of a vascular interventional device according to a fourth embodiment of the present invention.

[0182] Since the fourth embodiment of the present invention differs from the first embodiment of the present invention only in the structure of the first and second Ziploc members, a detailed description of the remaining components will be omitted, and their reference numerals will refer to those in the previous figures.

[0183] As shown in Figures 26 to 28, according to a fourth embodiment of the present invention, the Ziploc unit 120 may include a first Ziploc member 421 and a second Ziploc member 422.

[0184] The first ziplock member 421 and the second ziplock member 422 may be arranged to surround the outer surface of the treatment tool in the longitudinal direction, gradually joining together as the treatment tool is pulled out in the longitudinal direction.

[0185] This prevents the treatment tools from being exposed to the outside, potentially preventing internal infections caused by contamination of the tools.

[0186] According to a fourth embodiment of the present invention, the first Ziploc member 421 may include a plurality of first guide blocks 421a.

[0187] The plurality of first guide blocks 421a may extend in one direction while being joined together with each other.

[0188] In this case, one surface of each first guide block 421a may be provided with a first stepped portion (not shown) in the longitudinal direction, which is connected in one direction when the joint is connected.

[0189] According to a fourth embodiment of the present invention, the second ziplock member 422 can surround the treatment tool in the longitudinal direction while being paired with the first ziplock member 421, thereby preventing the treatment tool from being exposed to the outside.

[0190] Such a second ziplock member 422 may include a plurality of second guide blocks 422a.

[0191] The plurality of second guide blocks 422a may extend in one direction while being joined together with each other.

[0192] The multiple first guide blocks 421a constituting the first Ziploc member 421 and the multiple second guide blocks 422a constituting the second Ziploc member 422 may interlock with each other when they meet in the longitudinal direction.

[0193] On the other hand, one surface of each second guide block 422a may be provided with a second stepped portion (not shown) in the longitudinal direction, which is connected in one direction when the joint is connected. When such a second stepped portion (not shown) meets the first stepped portion (not shown) of the first ziplock member 421, it can form a seating hole in which a treatment tool can be seated in the longitudinal direction.

[0194] According to a fourth embodiment of the present invention, a multi-joint joint is formed by a plurality of first guide blocks 421a forming the first ziplock member 421 and a plurality of second guide blocks 422a forming the second ziplock member 422, which meet and interlock with each other in the longitudinal direction. As the ziplock member 421 and the second ziplock member 422 are pulled out in the longitudinal direction of the treatment tool, they gradually connect with each other and surround the outer circumferential surface of the treatment tool in the longitudinal direction.

[0195] Although the present invention has been described in detail with reference to preferred embodiments, the scope of the present invention is not limited to specific embodiments and should be interpreted according to the attached claims. Furthermore, a person with ordinary skill in the art will understand that various modifications and variations are possible without departing from the scope of the present invention.
