For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] Embodiment 1:

[0048] like Figure 2-4 As shown, embodiment 1 of the present application provides an interventional instrument manipulation auxiliary part 10, including a support frame 16 and an adjusting member 17, the support frame 16 includes a first guide slide rod 14 and a base 11, the first guide slide rod 14 is installed on the base 11; at least one first movable component 15 is installed on the first guide slide rod 14, the first movable component 15 is provided with a first slide groove 1514, the first guide slide rod 14 is passed through the first slide groove 1514; the adjusting member 17 is arranged on the support frame 16, and the adjusting member 17 is linked with the first guide slide rod to adjust the position of the first guide slide rod 14.

[0049] In this embodiment, the first guide slide bar 14 can be arranged on the base 11 in parallel or at an angle (i.e., tilted) to the base 11. Preferably, the first guide slide bar 14 is tiltedly arranged on the base 11. The adjusting member 17 can adjust the position of the first guide slide bar 14 in the transverse direction (i.e., in the direction parallel to the base 11). Specifically, the adjusting member 17 includes a second guide slide bar 12 and a second moving assembly 13 installed on the second guide slide bar 12. The second guide slide bar 12 is arranged on the base 11, and a rack is provided on the second guide slide bar 12.

[0050] like Figure 4As shown, the second moving assembly 13 includes a slider 131, a rotating shaft 132, a knob 133 and a locking mechanism 134. The slider 131 includes two side walls 135 and two end walls 136. The slider 131 is provided with a slide groove 1312, at least one side wall 135 is provided with a through hole 1313, at least one slot 1311 is provided on the top of the slider 131, and the first guide slide rod 14 is installed in the slot 1311 via a column; one end of the rotating shaft 132 is provided in the through hole 1313 and a gear is provided on the rotating shaft 132, and the gear is used to drive with the rack of the second guide slide rod 12. In cooperation, the other end of the rotating shaft 132 protrudes from the through hole 1313 and is connected to the knob 133. By operating the knob 133, the rotating shaft 132 is driven to rotate so that the gear of the rotating shaft 132 rotates, so that the gear of the rotating shaft 132 is matched with the second guide slide rod 12 in transmission, thereby driving the slider 131 to move on the second guide slide rod 12; the locking mechanism 134 is used to lock the second movable component 13. After locking, the second movable component 13 and the second guide slide rod 12 can be prevented from having relative movement. When unlocked, the second movable component 13 and the second guide slide rod 12 can have relative movement. Through the above arrangement, when the second guide slide bar 12 is arranged on the base 11 in a transverse direction, the second movable assembly 13 can be driven to move in the transverse direction by operating the knob 133, thereby driving the first guide slide bar 14 to move in the transverse direction; it can be understood that when the second guide slide bar 12 is arranged on the base 11 in an angled manner with the transverse direction (i.e., in a non-transverse direction), the second movable assembly 13 can be driven to move in a non-transverse direction by operating the knob 133, thereby driving the first guide slide bar 14 to move in the non-transverse direction. Therefore, the first guide slide bar 14 is arranged on the second movable assembly 13, and the adjustment range of the first guide slide bar 14 can be increased in the transverse direction or the non-transverse direction by operating the knob 133.

[0051] The locking mechanism 134 includes a resisting member 1341, which resists the second guide slide bar 12 to lock the slider 131 at the position of the second guide slide bar 12 or moves away from the second guide slide bar 12 to unlock the slider 131 at the position of the second guide slide bar 12. When the resisting member 1341 moves away from the second guide slide bar 12, the slider 131 is in an unlocked state; when the resisting member 1341 resists the second guide slide bar 12, the slider 131 is in a locked state. It can be understood that the locking mechanism 134 is used to fix the second movable assembly 13 at the current position after the second movable assembly 13 moves into place, so that it cannot move further, thereby effectively fixing the first guide slide bar 14 to prevent the first guide slide bar 14 from moving improperly during the operation and affecting the normal operation.

[0052] Specifically, a positioning hole connected to the slide groove 1312 is provided on the right side wall of the slider 131, and a resisting member 1341 is inserted into the positioning hole. The resisting member 1341 moves along the axis of the positioning hole to press against or away from the second guide slide bar 12. It can be understood that the resisting member 1341 has a thread feature, and the resisting member 1341 can be installed in the positioning hole by threaded connection. When the second moving component 13 needs to be fixed, the screwing depth of the resisting member 1341 in the positioning hole can be controlled by the handle 1342 to resist the second guide slide bar 12 to prevent the slider 131 from moving. Of course, the locking mechanism 134 can also be provided on the left side wall of the slider 131, and correspondingly, the positioning hole is provided on the left side wall of the slider 131. The matching mode between the first moving component 15 and the first guide slide bar 14 is the same as the matching mode between the second moving component 13 and the second guide slide bar 12.

[0053] like Figure 2 , 35 As shown, the interventional instrument manipulation auxiliary 10 can be used to position the interventional instrument during the interventional medical surgery, so as to stably support the interventional instrument, and the interventional instrument is detachably connected to the first movable component 15. The interventional instrument is detachably positioned on the first movable component 15 of the interventional instrument manipulation auxiliary 10. When the initial position of the first guide slide 14 is not in the expected working position, the position of the first guide slide 14 is adjusted by operating the adjustment member 17 (for example, the lateral, longitudinal and / or tilt angle), and then the interventional instrument can be moved to a certain position by moving the first movable component 15, for example, the interventional instrument is positioned near the patient's body or near the surgical site. When the interventional instrument includes at least two parts that can move relative to each other, each part is detachably positioned on the first movable component 15 corresponding to the interventional instrument manipulation auxiliary 10, and each part of the interventional instrument can be moved to a certain position by moving the first movable component 15 to facilitate the interventional surgery.

[0054] In some embodiments, the number of first movable components 15 is 3, and the 3 first movable components 15 correspond one by one to the valve clip manipulation device 210, the bending sheath 220, and the guide sheath 230 of the interventional instrument. The number of first movable components 15 can be determined by the number of parts of the interventional instrument that need to be fixed. The number of first movable components 15 can also be 1, 2, or other numbers. The first movable components 15 can be detachably mounted on the support frame 16, and different numbers of first movable components 15 can be set on the support frame 16 according to actual needs.

[0055] like Figure 2-3As shown in Figures 5-7, the support frame 16 includes a first guide slide rod 14, and the first guide slide rod 14 is provided with at least one rack along its length direction. The first moving component 15 includes a slider 151, a bracket 152, a rotating shaft 153, a knob 154 and a locking mechanism 155. The slider 151 is provided with a sliding groove 1514 running through its two opposite end walls. The slider 151 includes an opposite second side wall 1515 and a first side wall 1516. The first side wall 1516 is provided with a through hole 1512 connected to the sliding groove 1514. The rotating shaft 153 is installed on the slider 151 through the through hole 1512; the rotating shaft 153 includes a first round wheel 1532, the second side wall 1515 or the first side wall 1516 supports the first round wheel 1532, and the outer periphery 1533 of the first round wheel 1532 abuts against the second side wall 1515 or the first side wall 1516; the average width of the outer periphery 1533 of the first round wheel 1532 is 10%-90% of the width of the center of the first round wheel 1532. A positioning hole 1513 for assembling the locking mechanism 155 is provided on the side wall of the slider 151 . Since the locking mechanism 155 has the same structure as the locking mechanism 134 of the second moving assembly, the details thereof will not be described again.

[0056] like Figure 7 As shown, specifically, a first round wheel 1532 is provided at one end of the rotating shaft 153, and the outer circumference of the first round wheel 1532 has an outer round angle. When the rotating shaft 153 is installed on the slider 151, the first side wall 1516 supports the first round wheel 1532 and the rotating shaft 153 can rotate in the slider 151. By providing the outer round angle on the outer circumference of the first round wheel 1532, the average width L1 of the outer circumference 1533 of the first round wheel 1532 is smaller than the width L2 of the center of the first round wheel 1532, so the contact area between the outer circumference 1533 of the first round wheel 1532 and the first side wall 1516 can be reduced, so when the rotating shaft 153 rotates, the abnormal sound between the first round wheel 1532 and the first side wall 1516 can be avoided. Generally, the average width L1 is 10%-90% of the width L2; preferably, the average width L1 is 20%-80% of the width L2; more preferably, the average width L1 is 40%-60% of the width L2.

[0057] The first guide slide bar 14 includes at least one rack along its length direction, the rotating shaft 153 also includes a gear 1531 meshed with the rack, and the first movable component 15 also includes a knob 154, and the knob 154 is connected to one end of the rotating shaft 153. The operating knob 154 can drive the gear 1531, and the gear 1531 rotates along the rack to drive the first movable component 15 to move along the first guide slide bar 14. The rotation amount of the control gear 1531 can adjust the movement amount of the first movable component 15, so as to achieve fine-tuning, avoid the situation that the first movable component 15 moves excessively or does not move into place, that is, avoid the excessive movement or mismovement of the interventional instrument, ensure the smooth progress of the operation, reduce the risk of surgery, and facilitate regulation.

[0058] In some embodiments, the first round wheel 1532 and the gear 1531 can be fixedly sleeved on the rotating shaft 153 by welding, and the first round wheel 1532 and the gear 1531 are coaxial and rotate with the rotation of the rotating shaft 153. In other embodiments, the first round wheel 1532 and the gear 1531 can be fixedly installed on the rotating shaft 153 by bearing assembly or other matching methods, so that the first round wheel 1532 and the gear 1531 rotate together with the rotating shaft 153.

[0059] In some embodiments, the knob 154 can be fixed to the shaft 153 by screws. One end of the shaft 153 where the knob 154 is mounted is provided with at least one flat surface, the knob 154 is sleeved on the shaft 153, and the mounting hole of the knob 154 is provided with another flat surface. The cooperation of the two flat surfaces ensures that when the shaft 153 and the knob 154 are connected, the two will not rotate relative to each other, and the assembly is easy.

[0060] In some embodiments, the first round wheel 1532 is cylindrical and the diameter of the first round wheel 1532 is greater than the outer diameter of the gear 1531. Specifically, the radius of the first round wheel 1532 is greater than the distance from the axis of the rotating shaft 153 to the upper surface of the first guide slide 14. Therefore, when the first moving assembly 15 is installed on the first guide slide 14, the first round wheel 1532 is located between the bottom surface of the blind hole and the left surface of the first guide slide 14 to limit the movement of the first round wheel 1532 along the axis of the rotating shaft 153, but does not limit the first round wheel 1532 to rotate following the rotation of the gear 1531, so that the slider 151 can move relative to the length direction of the first guide slide 14.

[0061] like Figure 3 , 6As shown, the right side wall (i.e., the second side wall 1515) of the slider 151 is provided with a through hole 1512, and the left side wall (i.e., the first side wall 1516) is provided with a blind hole. The axis lines of the through hole 1512 and the blind hole coincide with each other, and the through hole 1512 is connected to the blind hole and the slide groove 1514 at the same time. When the rotating shaft 153 is installed on the slider 151, the first round wheel 1532 passes through the through hole 1512 and is rotatably accommodated in the blind hole, and the gear 1531 is located between the through hole 1512 and the blind hole and is partially accommodated in the slide groove 1514. It can be understood that the blind hole provides an installation space for the first round wheel 1532, and supports and limits the first round wheel 1532, thereby simplifying the structure of the slider 151 and the rotating shaft 153. The first round wheel 1532 can be partially accommodated in the blind hole, or, under the premise of clearance fit between the guide slide rod 13 and the first side wall 1516 of the slider 151, the first round wheel 1532 is entirely accommodated in the blind hole and is limited between the guide slide rod 13 and the first side wall 1516 of the slider 151. Preferably, the depth of the blind hole is equal to the width L2, and the first round wheel 1532 is just entirely accommodated in the blind hole. The first round wheel 1532 is accommodated in the blind hole through the through hole, so that the installation and disassembly of the rotating shaft 153 is more flexible and convenient. The clearance fit between the first round wheel 1532 and the blind hole makes the rotation of the first round wheel 1532 in the blind hole more stable, and the meshing rotation of the gear 1531 and the rack is also more stable. Specifically, the unilateral clearance fit between the first round wheel 1532 and the blind hole ranges from 0.02mm to 0.15mm, and preferably, the unilateral clearance fit between the first round wheel 1532 and the blind hole ranges from 0.05mm to 0.1mm. In other embodiments, the blind hole may be disposed on the right side wall (ie, the second side wall 1515 ) of the slider 151 , and the through hole may be disposed on the left side wall (ie, the first side wall 1516 ) of the slider 151 .

[0062] In some embodiments, Figure 8As shown, further, in the circumferential direction and axial direction of the first round wheel 1532, the outer periphery 1533a of the first round wheel 1532 is a curve, and any two adjacent points on the curve are staggered. By setting the outer periphery 1533a as a curve, the position of the second side wall 1515 that is used to abut against the outer periphery 1533a is constantly changed during the rotation of the rotating shaft 153a, so that the outer periphery 1533a can be prevented from continuously applying pressure to the same position of the second side wall 1515, and abnormal noise can be further prevented between the first round wheel 1532 and the first side wall 1516. At the same time, the second side wall 1515 can be evenly stressed, and the deformation of the part of the second side wall 1515 abutting against the outer periphery 1533a can be prevented, thereby affecting the rotation of the rotating shaft 153. Similarly, in the circumferential direction of the first circular wheel 1532, the average width of the curved outer edge 1533a is 10%-90% of the width L2; preferably, the average width of the curved outer edge 1533a is 20%-80% of the width L2; more preferably, the average width of the curved outer edge 1533a is 40%-60% of the width L2.

[0063] In some embodiments, Fig. 9 As shown, a second round wheel 1534 is provided at one end of the rotating shaft 153b, and the outer circumference of the second round wheel 1534 has an outer round angle. When the rotating shaft 153b is installed on the slider 151, the second side wall 1515 supports the second round wheel 1534 and the rotating shaft 153b can rotate in the slider 151. Similarly, the second round wheel 1534 has the same structure as the first round wheel 1532, which will not be described in detail.

[0064] In some embodiments, Fig.10 As shown, a first round wheel 1532 and a second round wheel 1534 are provided at one end of the rotating shaft 153c, and the gear 1531 is located between the first round wheel 1532 and the second round wheel 1534. The outer peripheries of the first round wheel 1532 and the second round wheel 1534 both have outer round angles. When the rotating shaft 153c is mounted on the slider 151, the first side wall 1516 and the second side wall 1515 support the first round wheel 1532 and the second round wheel 1534 respectively, and the rotating shaft 153b can rotate in the slider 151. Through the above arrangement, the rotating shaft 153c is supported by the first side wall 1516 and the second side wall 1515 at the same time, so the rotating shaft 153c can rotate more stably. In some embodiments, the second round wheel 1534 can be fixedly sleeved on the rotating shaft 153c by welding, and is spaced apart from the first round wheel 1532. The first round wheel 1532, the second round wheel 1534 and the gear 1531 are coaxial and rotate with the rotation of the shaft 153c. In other embodiments, the second round wheel 1534 can be mounted on the shaft 153c by bearing assembly or other assembly methods, so that the second round wheel 1534 rotates with the shaft 153c.

[0065] In some embodiments, Figure 11-12 As shown, the rotating shaft 153d is provided with a first round wheel 1532 and a second round wheel 1534a, and the gear 1531 is located between the first round wheel 1532 and the second round wheel 1534a. The second round wheel 1534a is provided with a plurality of grooves 1536 and a roller 1535, and the roller 1535 can be rotatably installed in the groove 1536 and the roller 1535 at least partially protrudes from the groove 1536, so that the roller 1535 can protrude from the outer circumference of the second round wheel 1534. When the rotating shaft 153d is installed on the slider 151, the roller 1535 abuts against the second side wall 1515; when the rotating shaft 153d rotates, the plurality of rollers 1535 rotate and abut against the second side wall 1515 in turn, and each roller 1535 is not The second side wall 1515 rotates continuously, so that the contact portion between each roller 1535 and the second side wall 1515 changes continuously, thereby reducing the friction between the two, making the operation of the rotating shaft 153d smoother; at the same time, the contact area between the second side wall 1515 and the roller 1535 is smaller than the contact area between the second round wheel 1534a and the second side wall 1515, and the second side wall 1515 and the roller 1535 rotate and abut, so as to avoid abnormal noise between the second round wheel 1534a and the second side wall 1515 when the rotating shaft 153d rotates. Similarly, in the circumference of the second round wheel 1534a, the average width of the roller 1535 is 10%-90% of the width L2; preferably, the average width of the roller 1535 is 20%-80% of the width L2; more preferably, the average width of the roller 1535 is 40%-60% of the width L2.

[0070] Embodiment 2:

[0071] like Figure 20-21As shown, the second embodiment of the present application provides an interventional instrument manipulation aid 20 , which is different from the first embodiment in that the adjustment component of the interventional instrument manipulation aid 20 in the second embodiment is different.

[0072] The interventional instrument manipulation auxiliary part 20 includes a support frame 26 and an adjustment member 22, the support frame 26 includes a first guide slide rod 24 and a base 21, the first guide slide rod 24 is installed on the base 21; at least one first movable component 25 is installed on the first guide slide rod 24, the first movable component 25 is provided with a first slide groove, and the first guide slide rod 24 is passed through the first slide groove; the adjustment member 22 is arranged on the support frame 26, and the adjustment member 22 is linked with the first guide slide rod 24 to adjust the position of the first guide slide rod 24.

Among them, one end of the first connection member 222 is fixedly connected to the operating portion 223, and one end of the first connection member 222 is also movably connected to one end of the second connection member 221; during operation, the second connection member 221 remains stationary, and the rotation of the adjustment operating portion 223 can drive the first connection member 222 to rotate, thereby driving the first guide slide bar 24 to rotate, so as to adjust the inclination angle of the first guide slide bar 24, thereby increasing the adjustment range of the first guide slide bar 24 in the circumferential direction of the operating portion 223.

[0074] In addition, a locking mechanism may be provided on the operating part 223, and the locking mechanism includes a resisting member, and the locking method thereof is similar to the locking mechanism 134 in the first embodiment. The resisting member presses the second connecting member 221 to lock the position of the first connecting member 222 to prevent the first connecting member 222 and the second connecting member 221 from relative movement; or the resisting member moves away from the second connecting member 221 to unlock the first connecting member 222 so that the first connecting member 222 and the second connecting member 221 can move relative to each other. When the resisting member moves away from the second connecting member 221, the adjusting member 22 is in an unlocked state; when the resisting member presses the second connecting member 221, the adjusting member 22 is in a locked state. It can be understood that the locking mechanism is used to fix the first connecting member 222 in the current position after the first connecting member 222 moves into place, so that it cannot move further, thereby effectively fixing the first guide slide 24 to prevent the first guide slide 24 from improperly moving during the operation and affecting the normal operation.

[0075] In some embodiments, Figure 22-23As shown, the interventional instrument manipulation auxiliary component 20a includes an adjustment member 22a, and the adjustment member 22a includes a first connecting member 224, a first connecting portion 226, and a second connecting portion 225. One end of the first connecting member 224 is connected to the first guide slide bar 24 through the first connecting portion 226, and the other end of the first connecting member 224 is connected to the second connecting portion 225, wherein the first connecting portion 226 and the second connecting portion 225 are respectively fixedly connected to the first guide slide bar 24 and the base 21, and the first connecting member 224 is movably connected to at least one of the first connecting portion 226 and the second connecting portion 225. For example, a through hole is provided at one end of the first connecting member 224, and a shaft is correspondingly provided at the first connecting portion 226. One end of the first connecting member 224 is rotatably connected to the first connecting portion 226. By adjusting the position of the first connecting member 224, the circumferential position of the first guide slide bar 24 can be adjusted, thereby increasing the adjustment range of the first guide slide bar 24. Of course, other matching modes may be used between the first connecting member 224 and the first connecting portion 226 as long as the two can achieve relative movement.

[0076] In addition, a locking mechanism may be provided on the first connecting part 226 and / or the second connecting part 225, and the locking mechanism includes a resisting member, and the locking method thereof is similar to the locking mechanism 134 in the first embodiment, wherein the resisting member presses the first connecting part 224 to lock the position of the first connecting part 224 to prevent the first connecting part 224 from moving relative to the first connecting part 226 and / or the second connecting part 225; or the resisting member moves away from the first connecting part 224 to unlock the first connecting part 224 so that the first connecting part 224 can move relative to the first connecting part 226 and / or the second connecting part 225. It can be understood that the locking mechanism is used to fix the first connecting part 224 at the current position after the first connecting part 224 moves into position, and cannot move further, so that the first guide slide bar 24 can be effectively fixed, and prevent the improper movement of the first guide slide bar 24 during the operation from affecting the normal operation.

When the guide rail 2251 is arranged on the base 21 in a transverse direction, one end of the first connection member 224 can move in the transverse direction, thereby driving the first guide slide 24 to move in the transverse direction; it can be understood that when the guide rail 2251 is arranged on the base 21 in an angled manner with the transverse direction (i.e., in a non-transverse direction), one end of the first connection member 224 moves in a non-transverse direction, thereby driving the first guide slide 24 to move in the circumferential direction, further increasing the adjustment range of the first guide slide 24.

[0078] In addition, a locking mechanism may be provided on the first connecting part 226 and / or the second connecting part 225b, and the locking mechanism includes a resisting member, and the locking method thereof is similar to the locking mechanism 134 in the first embodiment, wherein the resisting member presses the first connecting part 224 to lock the position of the first connecting part 224 to prevent the first connecting part 224 from moving relative to the first connecting part 226 and / or the second connecting part 225b; or the resisting member moves away from the first connecting part 224 to unlock the first connecting part 224 so that the first connecting part 224 can move relative to the first connecting part 226 and / or the second connecting part 225b. It can be understood that the locking mechanism is used to fix the first connecting part 224 in the current position after the first connecting part 224 moves into place, and cannot move further, so that the first guide slide bar 24 can be effectively fixed, and prevent the improper movement of the first guide slide bar 24 during the operation from affecting the normal operation.
