Description

[Technical field]

[0001] The following embodiment relates to a surgical tool control device. [Background technology]

[0002] In the process of conventional percutaneous coronary intervention (PCI), the practitioner is exposed to continuous radiation exposure, and it takes a lot of time and money to train skilled doctors to a level where they can perform stable procedures. In addition, there are large disparities in the level of completion of procedures between practitioners, regions, and hospitals, making it difficult to universally provide high-quality medical services.

[0003] To overcome these shortcomings, surgical assistant robots have been introduced, but most of them are configured to control only one surgical tool. Conventional surgical assistant robots are only applicable to treatments for lesions with low difficulty, and are limited in that they are difficult to apply to cases that require the use of multiple surgical tools, such as chronic total occlusion (CTO) lesions.

[0004] Therefore, there is a need for a surgical tool control device capable of independently controlling a plurality of surgical tools and guide catheters so that the device can be applied to complex PCI.

[0031] FIG. 1 is a perspective view of a treatment tool control device according to an embodiment. FIG. 2 is a plan view of the treatment tool control device according to an embodiment. FIG. 3 is a diagram showing a state in which the treatment tool control device according to an embodiment is used. FIG. 4 shows a process in which a roller module of a treatment tool control assembly according to an embodiment moves a treatment tool forward / backward. FIG. 5 shows a process in which a roller module of a treatment tool control assembly according to an embodiment rotates a treatment tool.

[0032] 1 to 5, the surgical tool control assembly 100 can independently control a plurality of surgical tools T. Here, the surgical tool T means a surgical tool having a longitudinal direction. For example, the surgical tool T may include various surgical tools such as a guide wire and / or a balloon catheter having a longitudinal direction. However, this is merely an example, and the type of the surgical tool T is not limited. The surgical tool control device 100 can realize forward / backward movement and rotation of the surgical tool T through the rotation and vertical movement of the roller module 22 described later. Specifically, as shown in FIG. 4, in a state where the first roller module 22a and the second roller module 22b are positioned adjacent to each other and hold the first surgical tool Ta therebetween, the roller members 222a and 222b rotate in one direction or the other, so that the first surgical tool Ta held therebetween can be advanced or retreated along the longitudinal direction. Also, as shown in FIG. 5, the first roller module 22a and the second roller module 22b are positioned adjacent to each other, and at least one of the roller modules 22 can move vertically while holding a treatment tool therebetween, thereby rotating the treatment tool held therebetween.

[0033] Referring to Fig. 3, the treatment tool control device 100 can independently control four treatment tools Ta, Tb, Tc, and Td through five roller modules 22a, 22b, 22c, 22d, and 22e. The treatment tool control device 100 can grip or release the treatment tool T between each roller module 22 through the horizontal movement of the roller modules 22. For example, Fig. 3 shows a state in which the first treatment tool Ta is gripped by the first roller module 22a and the second roller module 22b, and the third treatment tool Tc is gripped by the third roller module 22c and the fourth roller module 22d. A more specific method of gripping the treatment tools will be described later.

[0034] The treatment tool control device 100 according to one embodiment includes a main housing 1, a treatment tool control assembly 2, a guide catheter control assembly 3, a connecting arm 4, a housing tilting portion 5, a clamping portion 6, a treatment tool supporter 7, and a Y connector holder 8.

[0035] 1 and 2, the main housing 1 may form the exterior of the treatment tool control device 100. For example, the main housing 1 may be connected to a slave-based robot arm. That is, the treatment tool control device 100 functions as an end effector connected to the slave-based robot arm. The main housing 1 may be provided with a switch or a handle for adjusting the position and / or tilting of the main housing 1. The main housing 1 may be provided with a display panel for conveying information regarding a method of using the device and a status of the device to a user.

[0036] Figure 6 is a perspective view of a procedure tool control assembly according to one embodiment, Figure 7 is a bottom perspective view of a procedure tool control assembly according to one embodiment, Figure 8 is a front view of a procedure tool control assembly according to one embodiment, and Figure 9 is a bottom view of a procedure tool control assembly according to one embodiment.

[0037] 3 and 6 to 9, the treatment tool control assembly 2 can control the treatment tool T. The treatment tool control assembly 2 can grip and release the treatment tool T. The treatment tool control assembly 2 can move and rotate the gripped treatment tool T in the longitudinal direction.

[0038] The treatment tool control assembly 2 includes a frame 21, a roller module 22, and a horizontal movement unit 23.

[0039] nothing.

[0040] The frame 21 can form a base frame on which a roller module 22 and a horizontal movement unit 23, which will be described later, are provided. That is, the frame 21 is connected to the main housing 1, and the roller module 22 and the horizontal movement unit 23 are connected to the frame 21.

[0041] A plurality of roller modules 22 may be provided and connected to the frame 21. For example, the roller modules 22 include a first roller module 22a, a second roller module 22b, a third roller module 22c, a fourth roller module 22d, and a fifth roller module 22e. The first roller module 22a, the second roller module 22b, the third roller module 22c, the fourth roller module 22d, and the fifth roller module 22e may be arranged side by side. However, this is merely an example, and the number of roller modules 22 is not limited thereto.

[0042] A treatment tool T may be held between two adjacent roller modules 22. To this end, at least one of the roller modules 22 can move horizontally toward the other roller modules 22. For example, as shown in FIG. 3, the second roller module 22b can move horizontally toward the first roller module 22a so that the first treatment tool Ta is held between the first roller module 22a and the second roller module 22b. In this case, the second treatment tool Tb located between the second roller module 22b and the third roller module 22c can be released from the grip. Conversely, the second roller module 22b can move horizontally toward the third roller module 22c so that the second treatment tool Tb is held between the second roller module 22b and the third roller module 22c. In this case, the first treatment tool Ta located between the first roller module 22a and the second roller module 22b can be released from the grip.

[0043] Similarly, the fourth roller module 22d can move horizontally toward the third roller module 22c so that the third treatment tool Tc is held between the third roller module 22c and the fourth roller module 22d. In this case, the fourth treatment tool Td located between the fourth roller module 22d and the fifth roller module 22e can be released from the grip. Conversely, the fourth roller module 22d can move horizontally toward the fifth roller module 22e so that the fourth treatment tool Td is held between the fourth roller module 22d and the fifth roller module 22e. In this case, the third treatment tool Tc located between the third roller module 22c and the fourth roller module 22d can be released from the grip.

[0044] In this way, according to the structure in which the movable roller module 22 can move horizontally toward the roller modules 22 on both sides between the roller modules 22 located on both sides, it is possible to selectively hold each treatment tool T. Also, since the distance between the roller modules 22 can be sufficiently widened in order to load the treatment tool T, the thickness of the treatment tool T that can be held is not limited. In other words, the versatility of the treatment tool control device 100 can be improved in terms of being able to apply and hold treatment tools T of any thickness without being limited by the thickness of the treatment tool T.

[0045] As shown in FIG. 3, in a state where the first roller module 22a and the second roller module 22b hold the first treatment tool Ta, and the third roller module 22c and the fourth roller module 22d hold the third treatment tool Tc, the first treatment tool Ta and the third treatment tool Tc can be independently controlled (forward / reverse and rotated). Specifically, the first treatment tool Ta may be moved forward or backward in the longitudinal direction by the rotation of the roller members 222a and 222b of the first roller module 22a and the second roller module 22b (see FIG. 4). Also, the first treatment tool Ta may be rotated by the vertical movement of at least one of the roller members 222a and 222b of the first roller module 22a and the second roller module 22b (see FIG. 5). Similarly, the third treatment tool Tc may be moved forward or backward in the longitudinal direction by the rotation of the roller members 222c and 222d of the third roller module 22c and the fourth roller module 22d. Also, the third treatment tool Tc may be rotated by vertical movement of at least one of the roller members 222c, 222d of the third roller module 22c and the fourth roller module 22d. In summary, the first treatment tool Ta is controlled by the first roller module 22a and the second roller module 22b, and the third treatment tool Tc is controlled by the third roller module 22c and the fourth roller module 22d. Therefore, the first treatment tool Ta and the third treatment tool Tc can be controlled simultaneously as one set while being independent of each other. In this case, for example, one of the first treatment tool Ta and the third treatment tool Tc may be a balloon catheter, and the other may be a guidewire.

[0046] Similarly, in a state where the second roller module 22b and the third roller module 22c hold the second surgical tool Tb, and the fourth roller module 22d and the fifth roller module 22e hold the fourth surgical tool Td, the second surgical tool Tb and the fourth surgical tool Td can be independently controlled (forward / backward and rotated). In order to avoid repetition, the above-mentioned contents are incorporated for the specific control of the second surgical tool Tb and the fourth surgical tool Td. According to this structure, the second surgical tool Tb is controlled by the second roller module 22b and the third roller module 22c, and the fourth surgical tool Td is controlled by the fourth roller module 22d and the fifth roller module 22e. Therefore, the second surgical tool Tb and the fourth surgical tool Td can be controlled simultaneously while being independent of each other as a further set. In this case, for example, one of the second surgical tool Tb and the fourth surgical tool Td may be a balloon catheter, and the other may be a guidewire.

[0047] As a result, the treatment tool control device 100 can control the first treatment tool Ta and the third treatment tool Tc as one set, and the second treatment tool Tb and the fourth treatment tool Td as another set independently. Therefore, the treatment tool control assembly 100 can be easily applied to complicated intervention treatments that require multiple treatment tools.

[0048] Meanwhile, the above-mentioned set arrangement of the treatment tools is merely exemplary, and various sets of treatment tools may be arranged as necessary by changing the horizontal position of the roller module 22. Also, the second roller module 22b and the fourth roller module 22d have been described as moving horizontally between the roller modules 22a, 22c, and 22e located on both sides, respectively, but this is merely exemplary, and the first roller module 22a, the third roller module 22c, and the fifth roller module 22e may also be formed to be movable horizontally.

[0049] 10 and 11 are perspective and cross-sectional views of a roller module of a procedure tool control assembly according to one embodiment.

[0050] The roller module 22 shown in Figures 10 and 11 may be a roller module in which the roller member 222 is formed to be vertically movable. For example, as shown in Figure 6, the second roller module 22b, the third roller module 22c, and the fourth roller module 22d may be formed in the roller module 22 shown in Figures 10 and 11.

[0051] The roller module 22 shown in FIGS. 10 and 11 includes a roller plate 221 , a roller member 222 , a roller housing 223 , a rotational drive portion 224 , a vertical movement portion 225 , and a link structure support portion 226 .

[0052] The roller plate 221 may be coupled to the frame 21. That is, the roller plate 221 may function to couple the roller module 22 to the frame 21. A roller member 222 may be rotatably coupled to the roller plate 221.

[0053] The roller plate 221 includes a lower roller plate 2211 and an upper roller plate 2212. The lower roller plate 2211 is a part that is connected to the frame 21. The lower roller plate 2211 is provided with a rotation drive unit 224 and a vertical movement unit 225, which will be described later. The upper roller plate 2212 is a part that is located above the lower roller plate 2211 and to which the roller member 222 is rotatably connected. The upper roller plate 2212 can be moved vertically relative to the lower roller plate 2211 by the vertical movement unit 225, which will be described later.

[0054] The roller members 222 may be rotatably coupled to the upper roller plate 2212. The rotation axis of the roller members 222 may be perpendicular to the upper roller plate 2212. The roller members 222 are provided in a pair and are spaced apart along the longitudinal direction of the upper roller plate 2212.

[0055] The roller housing 223 may be coupled to an upper side of the upper roller plate 2212 and provide space for the roller members 222 to rotate. For example, the roller housing 223 may be fastened to the upper roller plate 2212 via a latch.

[0056] The rotation drive 224 is capable of rotating the roller members 222 relative to the roller plate 221. The rotation drive 224 may rotate the roller members 222 in one direction or the other. The rotation drive 224 may be provided on the lower roller plate 2211.

[0057] The rotation drive unit 224 includes a rotation drive motor 2241 , a rotation drive pulley 2242 , a spline nut 2243 , a spline shaft 2244 , and a shaft support unit 2245 .

[0058] The rotary drive motor 2241 can generate a rotary power for rotating the roller members 222. The rotary drive motor 2241 may be a motor that realizes both rotation in one direction and the other direction. The rotary drive pulley 2242 can receive the rotary power from the rotary drive motor 2241. For example, the rotary drive pulley 2242 can receive the rotary power via a timing belt or the like. The rotary drive pulleys 2242 are provided so as to correspond to the number of the roller members 222. For example, the rotary drive pulleys 2242 can be provided in a pair. The pair of rotary drive pulleys 2242 can be connected to a timing belt or the like to transmit the rotary power.

[0059] The spline nut 2243 may be rotated integrally with the rotation drive pulley 2242. For example, the spline nut 2243 may be disposed inside the rotation drive pulley 2242. The spline shaft 2244 may be fastened to the spline nut 2243. The spline shaft 2244 may be rotated integrally with the spline nut 2243. The roller member 222 may be connected to one side of the spline shaft 2244. According to this structure, the roller member 222 connected to one side of the spline shaft 2244 may be rotated by the rotation of the spline nut 2243.

[0060] That is, the rotary drive motor 2241 rotates the rotary drive pulley 2242 via a timing belt or the like, and as the rotary drive pulley 2242 rotates, the spline nut 2243 and the spline shaft 2244 rotate together, thereby allowing the roller member 222 connected to the spline shaft 2244 to rotate.

[0061] On the other hand, since the roller member 222 is moved in the vertical direction by the vertical moving part 225, it is important to prevent the spline shaft 2244 from shaking. To that end, the shaft support part 2245 may be provided between the rotation drive pulley 2242 and the spline shaft 2244. For example, the shaft support part 2245 may be fitted and connected so as to fill the empty space between the rotation drive pulley 2242 and the spline shaft 2244. For example, the shaft support part 2245 can fill the gaps generated on the upper and lower sides of the spline nut 2243 in the internal space of the rotation drive pulley 2242. In this way, by positioning the shaft support part 2245 between the rotation drive pulley 2242 and the spline shaft 2244, it is possible to prevent the spline shaft 2244 from shaking. For example, the shaft support part 2245 can improve the supporting force by including a flange shape. In order to prevent pinching due to thermal expansion during operation, it is preferable that the inner diameter tolerance of the shaft support 2245 after assembly is +0.0005 to +0.01 mm. For example, the shaft support 2245 may include a Teflon (registered trademark) material or an acetal material.

[0062] The vertical movement unit 225 can move the upper roller plate 2212 in the vertical direction relative to the lower roller plate 2211. That is, the vertical movement unit 225 can move the roller member 222 in the vertical direction by moving the upper roller plate 2212 in the vertical direction. The vertical movement unit 225 may be provided on the lower roller plate 2211.

[0063] The vertical movement unit 225 includes a vertical movement drive motor 2251 , a vertical movement pulley 2252 , a vertical movement lead screw nut 2253 , and a vertical movement lead screw 2255 .

[0064] The vertical movement drive motor 2251 can generate a rotational force for moving the roller member 222 in the vertical direction. The vertical movement drive motor 2251 may be a motor that realizes both rotation in one direction and the other direction. The vertical movement pulley 2252 may receive the rotational force from the vertical movement drive motor 2251. For example, the vertical movement pulley 2252 may receive the rotational force via a timing belt or the like. The vertical movement pulley 2252 may be provided in a pair. For example, the pair of vertical movement pulleys 2252 may be disposed at a distance from each other on one side and the other side of the lower roller plate 2211. The pair of vertical movement pulleys 2252 may be connected to a timing belt or the like to transmit the rotational force.

[0065] The vertical movement screw nut 2253 can rotate integrally with the vertical movement pulley 2252. For example, the vertical movement screw nut 2253 may be disposed inside the vertical movement pulley 2252. The vertical movement lead screw 2254 may be fastened to the vertical movement screw nut 2253. The vertical movement screw 2254 may move in the longitudinal direction by the rotation of the vertical movement screw nut 2253. The upper roller plate 2212 may be connected to one side of the vertical movement screw 2254. According to this structure, the vertical movement screw 2254 can move the upper roller plate 2212 in the vertical direction by the rotation of the vertical movement screw nut 2253.

[0066] That is, the vertical movement drive motor 2251 rotates the vertical movement pulley 2252 and the vertical movement lead screw nut 2253 together via a timing belt or the like, and the rotation of the vertical movement lead screw nut 2253 moves the vertical movement lead screw 2254 in the longitudinal direction, thereby moving the roller member 222 connected to the upper roller plate 2212 in the vertical direction.

[0067] Since the vertical moving part 225 increases the distance between the lower roller plate 2211 and the upper roller plate 2212, it is important to prevent the problem of the upper roller plate 2212 becoming inclined with respect to the lower roller plate 2211, that is, the problem of the axis of the spline shaft 2244 shaking. For this purpose, the link structure support part 226 can support the upper roller plate 2212 with respect to the lower roller plate 2211. Since the distance between the upper roller plate 2212 and the lower roller plate 2211 can be changed, the link structure support part 226 can have a link structure whose length can be changed in the vertical direction corresponding to the distance between the lower roller plate 2211 and the upper roller plate 2212. For example, the link structure support part 226 may have a structure like a pantograph. For example, the link structure support part 226 includes a link frame 2261 and a link 2262. The link frame 2261 may be provided between the lower roller plate 2211 and the upper roller plate 2212. The links 2262 can connect both sides of the link frame 2261 to the lower roller plate 2211 and the upper roller plate 2212, respectively. The links 2262 can be rotatably connected to both sides of the link frame 2261 and to the lower roller plate 2211 and the upper roller plate 2212, respectively, so that the vertical length of the link structure support part 226 can be changed. According to this structure, the link structure support part 226 is located between the lower roller plate 2211 and the upper roller plate 2212 and can support both sides of the upper roller plate 2212 with respect to the lower roller plate 2211, while being able to change its length in the vertical direction in accordance with the change in the distance therebetween, thereby preventing a problem in which the upper roller plate 2212 is inclined with respect to the lower roller plate 2211, i.e., a problem in which the axis of the spline shaft 2244 shakes.

[0068] Meanwhile, referring to FIG. 6, the first roller module 22a and the fifth roller module 22e include roller plates 221a, 221e, roller members 222a, 222e, roller housings 223a, 223e, and rotational drive units 224a, 224e. The first roller module 22a and the fifth roller module 22e may be formed as roller modules that do not move vertically. The roller plates 221a, 221e of the first roller module 22a and the fifth roller module 22e are formed as a single plate and directly connected to the frame 21, and do not include a separate vertical movement unit and a link structure support unit. Also, the first roller module 22a and the fifth roller module 22e may include one roller member 222a, 222e. However, this is merely an example, and the first roller module 22a and the fifth roller module 22e may also be formed as roller modules according to FIG. 10 and FIG. 11.

[0069] 6 to 9 again, the horizontal moving unit 23 can move the roller modules 22 in the horizontal direction. For example, in the case of FIGS. 6 to 9, the horizontal moving unit 23 can move the second roller module 22b and the fourth roller module 22d in the horizontal direction. However, this is merely an example, and the first roller module 22a, the third roller module 22c, and the fifth roller module 22e can also be formed to be movable in the horizontal direction. The horizontal moving unit 23 is provided in a number corresponding to the number of roller modules 22 to be moved. The horizontal moving unit 23 may be provided on the frame 21.

[0070] The horizontal movement unit 23 includes a horizontal movement drive motor 231 , a horizontal movement lead screw 232 , a horizontal movement lead screw nut 233 , and a connecting member 234 .

[0071] The horizontal movement drive motor 231 can generate rotational power for horizontally moving the roller module 22. The horizontal movement drive motor 231 may be a motor that realizes rotation in both one direction and the other direction.

[0072] The horizontal movement lead screw 232 is connected to the frame 21 in the horizontal direction. Rotational power can be transmitted to the horizontal movement lead screw 232 from the horizontal movement drive motor 231 via a timing belt, a pulley, etc. The horizontal movement lead screw 232 may be provided in a pair. For example, the pair of horizontal movement lead screws 232 may be disposed on one side and the other side of the frame 21, respectively. The pair of horizontal movement lead screws 232 are connected to each other via a timing belt, a pulley, etc., to transmit rotational power.

[0073] The horizontal movement lead screw nut 233 may be fastened to the horizontal movement lead screw 232. One side of the horizontal movement lead screw nut 233 is connected to the roller plate 221. For example, the horizontal movement lead screw nut 233 may be connected to the lower roller plate 2211 via a connecting member 234. A pair of horizontal movement lead screw nuts 233 may be connected to one side and the other side of the lower roller plate 2211, respectively. According to this structure, the horizontal movement lead screw nut 233 is moved in the longitudinal direction of the horizontal movement lead screw 232 by the rotation of the horizontal movement lead screw 232, so that the roller plate 221 connected to the horizontal movement lead screw nut 233 can move in the horizontal direction.

[0074] That is, the horizontal movement drive motor 231 rotates the horizontal movement lead screw 232 via a timing belt, pulleys, etc., and as the horizontal movement lead screw 232 rotates, the horizontal movement lead screw nut 233 and the lower roller plate 2211 connected thereto move horizontally along the longitudinal direction of the horizontal movement lead screw 232, i.e., the roller module 22 can be moved horizontally.

[0075] FIG. 12 is a perspective view of a housing tilting portion according to one embodiment.

[0076] 12, the housing tilting unit 5 can tilt the main housing 1 with respect to a position (e.g., a robot arm) where the treatment tool control device 100 is provided. As shown in FIG 12, the housing tilting unit 5 can tilt the main housing 1 with respect to a position (e.g., a robot arm) where the treatment tool control device 100 is provided through a configuration of a motor, a worm gear, a worm wheel, etc. However, this is merely an example, and the configuration of the housing tilting unit 5 is not limited thereto.

[0077] Fig. 13 is a perspective view of a clamping portion and a Y connector holder according to one embodiment.Figs. 14 to 16 are plan views showing an operation method of the clamping portion according to one embodiment.

[0078] 13 to 16, the clamping unit 6 can fix the position of the treatment tool T by clamping the treatment tool T when the treatment tool T is not held by the roller module 22. This configuration can prevent the treatment tool T from moving in an unintended direction when the treatment tool T is not held by the roller module 22. In addition, the clamping unit 6 can release the clamping of the treatment tool T held by the roller module 22 so that the treatment tool T can be controlled.

[0079] The clamping portion 6 may be provided to correspond to the number of treatment tools T. For example, referring to Fig. 3, the clamping portion 6 includes a first clamping portion 6a, a second clamping portion 6b, a third clamping portion 6c, and a fourth clamping portion 6d. Each of the clamping portions 6a, 6b, 6c, and 6d may be applied to each of the treatment tools Ta, Tb, Tc, and Td.

[0080] The clamping unit 6 has a structure capable of automatically clamping and unclamping the treatment tool T by horizontal movement of the roller module 22. The clamping unit 6 includes a clamp 61 and an elastic body 62.

[0081] Clamp 61 may be a member that clamps treatment tool T. For example, clamp 61 may be provided on Y connector holder 8 (see FIG. 13). In this case, a step 81 is formed on Y connector holder 8, and treatment tool T is clamped between clamp 61 and step 81 of Y connector holder 8. However, this is merely an example, and the member located opposite clamp 61 is not limited to step 81 of Y connector holder 8. In other words, treatment tool T can be clamped between clamp 61 and any member located opposite it.

[0082] The elastic body 62 presses the clamp 61 in one direction so that the clamp 61 can clamp the treatment tool T. For example, the elastic body 62 may press the clamp 61 toward the step 81 of the Y connector holder 8. FIG. 14 shows a state in which the roller modules 22 are located in a neutral position, that is, a state in which the adjacent roller modules 22 do not grip the treatment tool T. In the state shown in FIG. 14, the clamp 61 is pressed in one direction by the elastic force of the elastic body 62, and the treatment tool T can be clamped between the clamp 61 and the step 81 of the Y connector holder 8.

[0083] FIG. 15 shows a state in which the second roller module 22b has moved horizontally toward the first roller module 22a in order to hold the first treatment tool Ta between the first roller module 22a and the second roller module 22b. Referring to FIG. 15, in the process in which the second roller module 22b moves horizontally toward the first roller module 22a, the second roller module 22b can push the clamp 61a of the first clamping unit 6a in the other direction to release the clamping of the first treatment tool Ta. Therefore, the first treatment tool Ta is held between the first roller module 22a and the second roller module 22b, and at the same time, the clamping of the first clamping unit 6a is released, so that the first treatment tool Ta can be freely controlled. In addition, in the state shown in FIG. 15, the second treatment tool Tb that is not held by the second roller module 22b and the third roller module 22c may be clamped by the second clamping unit 6b and be in a state in which its movement is restricted.

[0084] FIG. 16 shows a state in which the second roller module 22b has moved horizontally toward the third roller module 22c in order to hold the second treatment tool Tb between the second roller module 22b and the third roller module 22c. Referring to FIG. 16, in the process in which the second roller module 22b moves horizontally toward the third roller module 22c, the second roller module 22b can push the clamp 61b of the second clamping unit 6b in the other direction to release the clamping of the second treatment tool Tb. Therefore, when the second treatment tool Tb is held between the second roller module 22b and the third roller module 22c, the clamping of the second clamping unit 6b is released at the same time, so that the second treatment tool Tb can be freely controlled (forward / backward and rotated). Also, at the same time, in the process in which the second roller module 22b moves horizontally toward the third roller module 22c, the clamp 61a of the first clamping unit 6a may be pressed again in one direction by the elastic force of the elastic body 62a to clamp the first treatment tool Ta. Therefore, even if the first treatment tool Ta is placed in an unclasped state, the clamping of the first clamping portion 6a can prevent the first treatment tool Ta from moving in an unintended direction.

[0085] As shown in Figs. 13 to 16, the clamp 61 may be provided rotatably with respect to the roll axis. In this case, the elastic body 62 may generate an elastic force that rotates the clamp 61 in a direction (one direction) toward the step 81 of the Y connector holder 8. The clamp 61 may also rotate in the other direction around the roll axis by contacting the roller housing 223 during the horizontal movement of the roller module 22. An end of the roller housing 223 may be formed into an inclined surface so that the clamp 61 can be smoothly rotated. However, this is merely an example, and the clamp 61 may be formed to move translationally in one direction and the other direction.

[0086] Although the above description has been given based on the first clamping portion 6a and the second clamping portion 6b, the third clamping portion 6c and the fourth clamping portion 6d can also clamp the third treatment tool Tc and the fourth treatment tool Td, respectively, in the same manner as described above. In order to avoid repetition, detailed descriptions of the third clamping portion 6c and the fourth clamping portion 6d will be omitted.

[0087] 1 to 3, the treatment tool supporter 7 may be provided in the main housing 1 and disposed behind the roller module 22. The treatment tool supporter 7 may support the rear side of the treatment tool T behind the roller module 22. For example, the treatment tool supporter 7 includes a groove in which the treatment tool T is seated, and a cover that covers the groove when the treatment tool T is seated in the groove. Therefore, a user can open the cover to seat the treatment tool T in the groove, and close the cover to support the treatment tool T on the treatment tool supporter 7. The treatment tool supporters 7 may be provided in a number corresponding to the number of treatment tools T. A plurality of treatment tool supporters 7 may be connected and fixed to one frame.

[0088] Figure 17 is a side view of an embodiment of a procedure tool control device, Figure 18 is a perspective view of an embodiment of a guide catheter control assembly, Figure 19 is a bottom perspective view of an embodiment of a guide catheter control assembly, and Figure 20 is a top view of an embodiment of a guide catheter control assembly.

[0089] 17 to 20, the guide catheter control assembly 3 can control a guide catheter. The guide catheter is disposed in front of the surgical tool control device 100 and can guide the path of at least one surgical tool T. The guide catheter control assembly 3 can grip and release the guide catheter. The guide catheter control assembly 3 can move and rotate the gripped guide catheter in the longitudinal direction.

[0090] The guide catheter control assembly 3 is disposed on the front side (i.e., the proximal end side) of the surgical tool control device 100. The guide catheter control assembly 3 is connected to the main housing 1 via a connecting arm 4. For example, one side of the connecting arm 4 may be connected to one side of the main housing 1, and the other side of the connecting arm 4 may be connected to a cover 30 on which the guide catheter control assembly 3 is mounted. The connecting arm 4 is rotatably connected to the main housing 1. The cover 30 may be rotatably and / or translatably connected to the connecting arm 4. The guide catheter control assembly 3 can be tilted and / or translated relative to the main housing 1 via the connecting arm 4. That is, the position of the guide catheter control assembly 3 can be adjusted by the connecting arm 4.

[0091] The guide catheter control assembly 3 can control the guide catheter in substantially the same manner as the procedure tool control assembly (e.g., procedure tool control assembly 2 of FIG. 6). The guide catheter control assembly 3 includes a frame 31, a roller module 32, and a horizontal movement section 33.

[0092] The frame 31 forms a base frame on which a roller module 32 and a horizontal movement unit 33, which will be described later, are provided. The frame 31 may be disposed at the front section (i.e., the proximal end) of the main housing 1. The frame 31 may be fixedly disposed inside a cover 30 connected to an end of the connecting arm 4. The roller module 32 and the horizontal movement unit 33 may be connected to the frame 31.

[0093] A plurality of roller modules 32 may be provided and connected to the frame 31. For example, the roller modules 32 include a first roller module 32a and a second roller module 32b. The first roller module 32a and the second roller module 32b may be arranged side by side. However, this is merely an example, and the number of roller modules 32 is not limited thereto.

[0094] A guide catheter can be held between two adjacent roller modules 32. To achieve this, at least one of the roller modules 32 can move horizontally toward the other roller modules 32. For example, the second roller module 32b can move horizontally toward the first roller module 32a so that the guide catheter is held between the first roller module 32a and the second roller module 32b. However, this is merely an example, and the first roller module 32a can also move horizontally toward the second roller module 32b.

[0095] According to this structure, the distance between the roller modules 32 can be sufficiently widened to grip the guide catheter, so that the thickness of the guide catheter to be gripped is not limited. In other words, since there is no limitation on the thickness of the guide catheter and guide catheters of any thickness can be gripped, the versatility of the treatment tool control device 100 is improved.

[0096] With the first roller module 32a and the second roller module 32b gripping the guide catheter, the guide catheter can be controlled (advance / reverse and rotated). Specifically, the guide catheter may be advanced or reversed in the longitudinal direction by rotation of the roller members 322a, 322b of the first roller module 32a and the second roller module 32b. Also, the guide catheter can be rotated by vertical movement of at least one of the roller members 322a, 322b of the first roller module 32a and the second roller module 32b.

[0097] 21 and 22 are perspective and cross-sectional views of a roller module of a guide catheter control assembly according to one embodiment.

[0098] The roller module 32 according to FIGS. 21 and 22 includes a roller plate 321, a roller member 322, a roller housing 323, a rotation drive part 324, and a vertical movement part 325.

[0099] 18 to 22, the roller plate 321 may be connected to the frame 31. That is, the roller plate 321 functions to connect the roller module 32 to the frame 31. A roller member 322 is rotatably connected to the roller plate 321.

[0100] The roller plate 321 includes an upper roller plate 3211 and a lower roller plate 3212. The upper roller plate 3211 is a part that is connected to the frame 31. The upper roller plate 3211 is provided with a rotation drive unit 324 and a vertical movement unit 325, which will be described later. The lower roller plate 3212 is a part that is located below the upper roller plate 3211 and to which the roller member 322 is rotatably connected. The lower roller plate 3212 can move vertically relative to the upper roller plate 3211 by the vertical movement unit 325, which will be described later.

[0101] The roller members 322 are rotatably connected to the lower roller plate 3212. The rotation axis of the roller members 322 is perpendicular to the lower roller plate 3212. The roller members 322 are provided in a pair and are spaced apart along the longitudinal direction of the lower roller plate 3212.

[0102] The roller housing 323 is coupled to the underside of the lower roller plate 3212 and provides a space for the roller members 322 to rotate in. For example, the roller housing 323 may be fastened to the lower roller plate 3212 via a latch.

[0103] 18 to 22, rotation drive unit 324 can rotate roller member 322 relative to roller plate 321. Rotation drive unit 324 can rotate roller member 322 in one direction or the other. Rotation drive unit 324 is provided on upper roller plate 3211.

[0104] The rotation drive unit 324 includes a rotation drive motor 3241 , a rotation drive pulley 3242 , a spline nut 3243 , a spline shaft 3244 , and a shaft support unit 3245 .

[0105] The rotary drive motor 3241 generates a rotary power for rotating the roller members 322. The rotary drive motor 3241 is a motor that realizes rotation in both one direction and the other direction. The rotary drive pulley 3242 receives the rotary power from the rotary drive motor 3241. For example, the rotary drive pulley 3242 may receive the rotary power via a timing belt or the like. The rotary drive pulleys 3242 are provided in a number corresponding to the number of the roller members 322.

[0106] The spline nut 3243 may be rotated integrally with the rotation drive pulley 3242. For example, the spline nut 3243 may be disposed inside the rotation drive pulley 3242. The spline shaft 3244 may be fastened to the spline nut 3243. The spline shaft 3244 may be rotated integrally with the spline nut 3243. The roller member 322 is connected to one side of the spline shaft 3244. With this structure, the roller member 322 connected to one side of the spline shaft 3244 may be rotated by the rotation of the spline nut 3243.

[0107] That is, the rotary drive motor 3241 rotates the rotary drive pulley 3242 via a timing belt or the like, and as the rotary drive pulley 3242 rotates, the spline nut 3243 and the spline shaft 3244 rotate together, thereby rotating the roller member 322 connected to the spline shaft 3244.

[0108] Meanwhile, since the roller member 322 moves in the vertical direction by the vertical moving part 325, it is important to prevent the spline shaft 3244 from shaking. For this purpose, the shaft support part 3245 may be located between the rotary drive pulley 3242 and the spline shaft 3244. For example, the shaft support part 3245 may be connected to the rotary drive pulley 3242 so as to fill the empty space between the rotary drive pulley 3242 and the spline shaft 3244. In this manner, by positioning the shaft support part 3245 between the rotary drive pulley 3242 and the spline shaft 3244, it is possible to prevent the spline shaft 3244 from shaking. For example, the shaft support part 3245 may include a flange shape to improve the supporting force. In order to prevent pinching due to thermal expansion during operation, it is preferable that the inner diameter tolerance of the shaft support part 3245 after assembly is formed to be +0.0005 to +0.01 mm. For example, the shaft support part 3245 may include a Teflon material or an acetal material.

[0109] 18 to 22, the vertical movement unit 325 can move the lower roller plate 3212 in the vertical direction relative to the upper roller plate 3211. That is, the vertical movement unit 325 moves the lower roller plate 3212 in the vertical direction, thereby moving the roller member 322 in the vertical direction. The vertical movement unit 325 can be provided on the upper roller plate 3211.

[0110] The vertical movement unit 325 includes a vertical movement drive motor 3251 , a vertical movement pulley 3252 , a vertical movement lead screw nut 3253 , and a vertical movement lead screw 3255 .

[0111] The vertical movement drive motor 3251 can generate rotational power for moving the roller member 322 in the vertical direction. The vertical movement drive motor 3251 is a motor that realizes both rotation in one direction and the other direction. The vertical movement pulley 3252 receives the rotational power from the vertical movement drive motor 3251. For example, the vertical movement pulley 3252 may receive the rotational power via a timing belt or the like. The vertical movement pulley 3252 is provided in a pair. For example, the pair of vertical movement pulleys 3252 may be spaced apart on one side and the other side of the upper roller plate 3211. The pair of vertical movement pulleys 3252 can be connected to a timing belt or the like to transmit the rotational power.

[0112] The vertical movement screw nut 3253 may be rotated integrally with the vertical movement pulley 3252. For example, the vertical movement screw nut 3253 may be disposed inside the vertical movement pulley 3252. The vertical movement lead screw 3254 may be fastened to the vertical movement screw nut 3253. The vertical movement screw 3254 may move in the longitudinal direction by the rotation of the vertical movement screw nut 3253. The lower roller plate 3212 may be connected to one side of the vertical movement screw 3254. According to this structure, the vertical movement screw 3254 can move the lower roller plate 3212 in the vertical direction by the rotation of the vertical movement screw nut 3253.

[0113] That is, the vertical movement drive motor 3251 rotates the vertical movement pulley 3252 and the vertical movement lead screw nut 3253 together via a timing belt or the like, and the rotation of the vertical movement lead screw nut 3253 causes the vertical movement lead screw 3254 to move in the longitudinal direction, thereby moving the roller member 322 connected to the lower roller plate 3212 in the vertical direction.

[0114] 18 to 22, the horizontal movement unit 33 can move the roller module 32 in the horizontal direction. For example, the horizontal movement unit 33 may move the second roller module 32b in the horizontal direction. However, this is merely an example, and the first roller module 32a may be formed to be movable in the horizontal direction. The horizontal movement unit 33 may be provided on the frame 31.

[0115] The horizontal movement unit 33 includes a horizontal movement drive motor 331 , a horizontal movement lead screw 332 , and a horizontal movement lead screw nut 333 .

[0116] The horizontal movement drive motor 331 generates rotational power for horizontally moving the roller module 32. The horizontal movement drive motor 331 may be a motor that realizes rotation in both one direction and the other direction.

[0117] The horizontal movement lead screw 332 may be connected to the frame 31 in a horizontal direction. Rotational power is transmitted to the horizontal movement lead screw 332 from the horizontal movement drive motor 331 via a timing belt, a pulley, etc. The horizontal movement lead screw 332 may be provided in a pair. For example, the pair of horizontal movement lead screws 332 may be disposed on one side and the other side of the frame 31, respectively. The pair of horizontal movement lead screws 332 may be connected to each other via a timing belt, a pulley, etc. to transmit rotational power.

[0118] The horizontal movement lead screw nut 333 may be fastened to the horizontal movement lead screw 332. One side of the horizontal movement lead screw nut 333 may be connected to the roller plate 321. For example, the horizontal movement lead screw nut 333 may be connected to the upper roller plate 3211 via a connecting member. A pair of horizontal movement lead screw nuts 333 may be connected to one side and the other side of the upper roller plate 3211, respectively. According to this structure, the horizontal movement lead screw nut 333 is moved in the longitudinal direction of the horizontal movement lead screw 332 by the rotation of the horizontal movement lead screw 332, so that the roller plate 321 connected to the horizontal movement lead screw nut 333 is moved in the horizontal direction.

[0119] That is, the horizontal movement drive motor 331 rotates the horizontal movement lead screw 332 via a timing belt and pulleys, etc., and as the horizontal movement lead screw 332 rotates, the horizontal movement lead screw nut 333 and the upper roller plate 3211 connected thereto move horizontally along the longitudinal direction of the horizontal movement lead screw 332, i.e., the roller module 32 can be moved horizontally.

[0120] Meanwhile, the roller module 32 according to Figures 21 and 22 may further include a link structure support 226, like the roller module 22 according to Figures 10 and 11. In addition, in the description of the guide catheter control assembly 3, the guide catheter control assembly 3 has been described and illustrated as being provided in a direction in which the roller members 322 face downward, but this is merely an example, and in one embodiment, the guide catheter control assembly 3 may be provided in a direction in which the roller members 322 face upward.

[0121] Although the embodiments of the present invention have been described in detail above with reference to the drawings, the present invention is not limited to the above-described embodiments, and a person having ordinary skill in the art can apply various technical modifications and variations based on the above. For example, the described techniques may be performed in an order different from that described, and / or the components of the described systems, structures, devices, circuits, etc. may be combined or combined in a form different from that described, or may be replaced or substituted by other components or equivalents to achieve appropriate results.
