Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a support device and an interventional medical system. Background Art

[0002] During interventional medical procedures, it's often necessary to maintain a medical device in a specific position to ensure safe and smooth operation. For example, a portion of the device must be positioned near the patient's body or near the surgical site during the procedure. Therefore, various auxiliary devices are used to stabilize the positioning of medical devices.

[0003] Typically, during surgery, medical equipment needs to be manipulated and repositioned. In many cases, a part of an interventional medical device must be moved relative to another part. The prior art discloses a support device comprising two support frames, each of which is provided with a slide groove for mounting a slidable bracket. The interventional medical device is mounted on the slidable bracket, and a part and / or another part of the medical device can be moved by pushing the slidable bracket. However, since the support device manually pushes the slidable bracket, the amount of movement is not easy to adjust and is prone to excessive movement. When a part of the medical device (such as a catheter or an implant) is located in the body, improper movement will affect the smooth progress of the operation and be dangerous to the patient. Summary of the Invention

[0004] In response to the defects of the prior art, the present invention provides a support device and an interventional medical system including the support device. The sliding assembly is moved along the guide rod through the engagement of the gear rack. The rotation amount of the control gear can adjust the movement amount of the sliding assembly to avoid excessive movement, thereby ensuring the smooth progress of the operation.

[0005] The present invention first provides a support device for fixing an interventional medical device, the support device including a support frame and at least one sliding assembly, the support frame including a guide slide rod, the guide slide rod being provided with at least one rack along its length direction; the sliding assembly including a slider, an adjustment mechanism provided on the slider and a bracket, the slider being sleeved on the guide slide rod, the adjustment mechanism including a gear engaged with the rack, the gear rotating along the rack to drive the sliding assembly to move along the guide slide rod, and the bracket being used for detachable connection with the interventional medical device.

[0006] The present invention also provides an interventional medical system, comprising: an interventional medical device and a support device, wherein the interventional medical device is fixed on a bracket of the support device; the support device comprises a support frame and at least one sliding assembly, the support frame comprises a guide rod, and the guide rod is provided with at least one rack along its length; the sliding assembly comprises a slider, an adjustment mechanism provided on the slider, and a bracket, the slider is sleeved on the guide rod, the adjustment mechanism comprises a gear engaged with the rack, the gear rotates along the rack to drive the sliding assembly to move along the guide rod, and the bracket is used to be detachably connected to the interventional medical device.

[0007] In the support device provided by the present invention, a gear of the sliding assembly meshes with a rack of the support frame. Rotation of the gear along the rack drives the sliding assembly along the guide rod, and the support frame is detachably connected to the interventional medical device. Therefore, the engagement of the gear and rack enables the sliding assembly to move along the guide rod. Controlling the rotation of the gear can adjust the movement of the sliding assembly, preventing excessive movement of the sliding assembly and, consequently, excessive or improper movement of the interventional medical device. This ensures smooth surgical procedures, reduces surgical risks, and facilitates control. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the use of directional terms is intended to better and more clearly illustrate and understand the present invention, and is not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0024] See also Figures 1 to 3One embodiment of the present invention provides a support device 100 for fixing an invasive medical device. The support device 100 includes a support frame 20 and at least one sliding assembly 50. The support frame 20 includes a guide rod 21, and the guide rod 21 is provided with at least one rack 210 along its length. The sliding assembly 50 includes a slider 51, an adjustment mechanism 53 provided on the slider 51, and a bracket 55. The slider 51 is sleeved on the guide rod 21, and the adjustment mechanism 53 includes a gear 530 (such as a gear 530) engaged with the rack 210. Figure 6 As shown), the gear 530 rotates along the rack 210 to drive the sliding assembly 50 to move along the guide rod 21, and the bracket 55 is used to be detachably connected to the interventional medical device.

[0025] In the support device 100 of the present invention, the gear 530 of the sliding assembly 50 is meshed with the rack 210 of the support frame 20, and the gear 530 rotates along the rack 210 to drive the sliding assembly 50 to move along the guide rod 21, and the bracket 55 is detachably connected to the interventional medical device. Therefore, the engagement of the gear 530 with the rack 210 allows the sliding assembly 50 to move along the guide rod 21, and the amount of rotation of the gear 530 can be controlled to adjust the amount of movement of the sliding assembly 50, thereby avoiding excessive movement of the sliding assembly 50, that is, avoiding excessive or improper movement of the interventional medical device, ensuring the smooth progress of the operation, reducing surgical risks, and facilitating regulation. In addition, the sliding assembly 50 of the support device 100 is only driven by the gear 530 and the rack 210 in one stage, with a simple structure and low production cost. The support device 100 is used to fix the interventional medical device, thereby stably supporting the interventional medical device.

[0026] like Figure 1 As shown, the guide rod 21 is slidably provided with three sliding assemblies 50, and each sliding assembly 50 can move along the guide rod 21. The interventional medical device may include three components that can move relative to each other, and each component can be detachably connected to the bracket 55 of the three sliding assemblies 50, thereby fixing the interventional medical device. The spacing between the components of the interventional medical device is adjusted by moving the corresponding sliding assembly 50 relative to the guide rod 21 to meet the requirements of the interventional medical surgery. The number of sliding assemblies 50 can be determined by the number of components that need to be fixed in the interventional medical device. The number of sliding assemblies 50 can also be one, two or other numbers. The sliding assembly 50 is detachably mounted on the guide rod 21, and different numbers of sliding assemblies 50 can be mounted on the guide rod 21 according to actual needs.

[0027] In the illustrated example, the guide rod 21 is provided with a rack 210 along its length, and correspondingly, the slider 51 of the sliding assembly 50 is provided with a gear 530 that meshes with the rack 210. Of course, the guide rod 21 may also be provided with multiple racks 210 along its length, and correspondingly, the slider 51 of the sliding assembly 50 may be provided with multiple gears 530, and the multiple gears 530 respectively mesh with the multiple racks 210.

[0028] like Figure 2 and Figure 3 As shown, the support frame 20 further includes a base plate 23 and at least one connecting member 25 disposed on the base plate 23. The guide slide 21 is disposed at one end of the connecting member 25 away from the base plate 23, and the length direction of the guide slide 21 is inclined to the base plate 23.

[0029] In this embodiment, the connecting member 25 is a support rod, and a support rod extends vertically from each of the two opposite ends of the front surface of the base plate 23, wherein the extension length of one support rod is smaller than the extension length of the other support rod. The guide rod 21 is supported by the ends of the two support rods away from the base plate 23, so that the guide rod 21 is tilted relative to the front surface of the base plate 23. Figure 3 As shown, a fixed angle a is formed between the length extension direction of the guide rod 21 and the front surface of the base plate 23. The fixed angle a can be determined based on the optimal puncture angle for the operation. The angle a ranges from greater than 0 degrees to less than 90 degrees; preferably, the angle a ranges from 15 degrees to 20 degrees; in this embodiment, the angle a is 18 degrees. The guide rod 21 and the connector 25 can be fixedly connected by welding or gluing, or can be detachably connected by snapping. The front surface of the base plate 23 refers to the surface facing the guide rod 21.

[0030] In other embodiments, the angle between the guide rod 21 and the base plate 23 can be adjusted. Specifically, for example, only one support rod is provided between the guide rod 21 and the base plate 23, the guide rod 21 and the support rod are hinged, and a positioning mechanism is provided between the guide rod 21 and the support rod. When the guide rod 21 rotates to a suitable angle relative to the support rod, the positioning mechanism is used to position the relative rotation between the guide rod and the support rod. Alternatively, a long support rod and a short support rod are provided between the guide rod 21 and the base plate 23, wherein the short support rod is hinged to one end of the guide rod 21, and the long support rod is movably connected to the other end of the guide rod 21, and the length of the long support rod is adjustable. The angle between the guide rod 21 and the front surface of the base plate 23 can be changed by adjusting the length of the long support rod.

[0031] The guide rod 21 includes a front surface 211 facing away from the base plate 23, a back surface 213 facing the base plate 23, and two side surfaces 214 located on opposite sides of the front surface 211. The rack 210 is disposed on one of the front surface 211, the back surface 213, and the two side surfaces 214. Figure 2As shown, the rack 210 is provided on the front face 211 of the guide rod 21, and the rack 210 extends along the length direction of the guide rod 21 to the opposite ends of the guide rod 21. The specific structure of the sliding assembly 50 is described in detail below using the rack 210 provided on the front face 211 of the guide rod 21 as an example.

[0032] Please also refer to Figure 1 、 Figures 4 to 8 The slider 51 is a rectangular block, which includes an upper side wall 511, a lower side wall 512 facing away from the upper side wall 511, a left side wall 514 and a right side wall 515 arranged on the left and right sides of the upper side wall 511, and two opposite end walls 516. The upper side wall 511 of the slider 51 is away from the substrate 23, and the lower side wall 512 faces the substrate 23. In this embodiment, the slider 51 can be made of plastic material. The slider 51 is provided with a slide groove 510, and the guide rod 21 is inserted into the slide groove 510. The lower side wall 512 is provided with an opening 513 along the extension direction of the slide groove 510, and the opening 513 is connected to the slide groove 510. The size of the opening 153 is larger than the size of the end of the connecting member 25 connected to the guide rod 21, so as to facilitate the movement of the slider 51 on the guide rod 21 without being stopped by the connecting member 25. Specifically, the slider 51 is provided with a convex-shaped sliding groove 510 , which passes through two opposite end walls 516 of the slider 51 . The slider 51 is sleeved on the guide rod 21 through the sliding groove 510 .

[0033] Preferably, the height of the first tooth adjacent to the end of the rack 210 is lower than that of the other teeth, making it easier for the guide rod 21 to be introduced into the slider 51. In addition, the size of the opening 212 is larger than the size of the end where the connector 25 is connected to the guide rod 21, so that the sliding assembly 50 can move on the entire guide rod 21.

[0034] In other embodiments, the lower side wall 512 of the slider 51 may also be closed, and the slider 51 of the sliding assembly 50 may be first sleeved on the guide rod 21 , and then the guide rod 21 is connected to the connector 25 .

[0035] like Figure 6 and Figure 7 As shown, the slider 51 is further provided with a gear mounting groove 5112 connected to the slide groove 510, and the gear 530 is rotatably accommodated in the gear mounting groove 5112. The guide slide 21 is passed through the slide groove 510, and the gear 530 is engaged with the rack 210 on the guide slide 21. Specifically, the upper side wall 511 of the slider 51 is provided with a gear through groove 5111 connected to the gear mounting groove 5112, and the gear mounting groove 5112 is located below the gear through groove 5111. The gear mounting groove 5112 includes a support surface 5113 (such as Figure 10(as shown), the support surface 5113 is used to support the toothless portion of the gear 530 (hereinafter referred to as the overlap ring 5303). A sealing cover 517 is housed within the gear slot 5111. The sealing cover 517 is used to seal the gear mounting slot 5112 after the gear 530 is installed therein. The inner surface of the gear slot 5111 is provided with locking holes surrounding the gear mounting slot 5112, and the sealing cover 517 is provided with a plurality of through-holes 5172. Once the gear 530 is accommodated in the gear mounting slot 5112 and the sealing cover 517 is accommodated in the gear slot 5111, a plurality of locking members pass through the through-holes 5172 and are locked into their corresponding locking holes.

[0036] Alternatively, as Figure 6 As shown, the adjustment mechanism 53 also includes a rotating shaft 531, which is rotatably inserted into the slider 51. The gear 530 is fixed to the rotating shaft 52. It will be understood that the gear 530 and the rotating shaft 531 cannot rotate relative to each other, and the rotation of the rotating shaft 52 drives the gear 530 to rotate. Specifically, the rotating shaft 531 includes a first connecting section 5312 at one end, a second connecting section 5314 at the opposite end, and a boss 5315 fixedly mounted between the first and second connecting sections 5312, 5314. The first and second connecting sections 5312, 5314, and boss 5315 of the rotating shaft 531 are integrally formed. The cross-sections of the first and second connecting sections 5312, 5314 are both waist-shaped. The first connecting section 5312 defines a first locking hole 5316, the second connecting section 5314 defines a second locking hole 5317, and the boss 5315 is a circular ring structure. Gear 530 has a connecting hole 5301 with a waist-shaped cross-section along its axial direction. A lap ring 5303 protrudes outward from one end of the gear 530, surrounding the connecting hole 5301. A through-hole 5305 is radially defined along the circumferential wall of the lap ring 5303. When the gear 530 is fitted over the first connecting section 5312, the through-hole 5305 faces the first locking hole 5316. A locking member is inserted into the through-hole 5305 and locked into the first locking hole 5316, securing the gear 530 to the rotating shaft 531. Because the transverse surface of the first connecting section 5312 is waist-shaped, and the transverse surface of the connecting hole 5301 of the gear 530 is waist-shaped, the insertion of the first connecting section 5312 into the connecting hole 5301 of the gear 530 prevents relative rotation between the rotating shaft 531 and the gear 530. The locking piece fixes the gear 530 and the rotating shaft 531 to prevent shaking between the gear 530 and the rotating shaft 531 when the rotating shaft 531 rotates.

[0037] Please also refer to Figure 6 - Figure 7 and Figure 10The slider 51 defines a shaft mounting groove 518 along the axial direction of the shaft 531. The shaft mounting groove 518 communicates with the gear mounting groove 5112, and the shaft 531 is rotatably received in the shaft mounting groove 518. Specifically, the shaft mounting groove 518 is defined in the right side wall 515 of the slider 51. The end of the shaft mounting groove 518 away from the right side wall 515 extends through the gear mounting groove 5112 to a position near the left side wall 514. Specifically, a through hole 5181 is formed at one end of the shaft mounting groove 518, and a blind hole 5182 is formed at the other end of the shaft mounting groove 518. Specifically, the through hole 5181 is formed in the right side wall 515, and the blind hole 5182 is formed inside the slider 51 on the side near the left side wall 514. When the rotating shaft 531 is received in the rotating shaft mounting groove 518 , one end of the rotating shaft 531 extends out of the through hole 5181 of the right side wall 515 , and the other end of the rotating shaft 531 abuts against the blind hole 5182 .

[0038] The adjustment mechanism 53 also includes a knob 537. The rotating shaft 531 is received in the rotating shaft mounting slot 518, and one end of the rotating shaft 531 extends through a through hole 5181 and is connected to the knob 537. Turning the knob 537 allows the rotating shaft 531 to rotate, thereby driving the gear 530 to rotate. Specifically, a waist-shaped connecting hole 5372 is provided in the middle of the knob 537 on the side facing the slider 51. A locking hole 5374 is radially defined on the outer wall of the knob 537, which communicates with the connecting hole 5372. When the knob 537 is mounted on the second connecting section 5314 of the rotating shaft 531, the locking hole 5374 faces the second locking hole 5317. A locking member is inserted into the locking hole 5374 and locked into the second locking hole 5317, securing the knob 537 to the rotating shaft 531. Several anti-slip ribs are provided on the outer wall of the knob 537 to facilitate operation of the knob 537.

[0039] The slider 51 defines a receiving groove 5180 around the periphery of the through-hole 5181. When the rotating shaft 531, which passes through the through-hole 5181 in the right side wall 515, is received in the rotating shaft mounting groove 518, the boss 5315 is received in the receiving groove 5180 and abuts the periphery of the through-hole 5181. This positions the first connecting section 5312 of the rotating shaft 531 within the slider 51, with the end of the first connecting section 5312 precisely abutting the blind hole 5182.

[0040] Specifically, the receiving groove 5180 may include a first sub-receiving groove 5184 and a second sub-receiving groove 5185 that are connected. The second sub-receiving groove 5185 is larger than the first sub-receiving groove 5184. The boss 5315 is received in the first sub-receiving groove 5184 and abuts against the inner wall of the first sub-receiving groove 5184. The first sub-receiving groove 5184 also accommodates a damping member 533 that abuts against the boss 5315. The second sub-receiving groove 5185 accommodates a pressing member 535 to compress the damping member 533. The second sub-receiving groove 5185 can be a rectangular groove, and the first sub-receiving groove 5184 can be a circular groove. The shaft mounting groove 518 connects the first sub-receiving groove 5184 and the second sub-receiving groove 5185. The inner surface of the second sub-receiving groove 5185 defines locking holes 5186 around the rotating shaft mounting groove 518. The pressing member 535 defines a through-hole 5351, into which the locking member 536 is inserted and locked. The pressing member 535 not only seals the rotating shaft mounting groove 518 but also compresses the damping member 533 and the boss 5315, preventing any shaking between the gear 530 and the rotating shaft 531 when the rotating shaft 531 rotates. Therefore, a locking member is not required to secure the gear 530 to the rotating shaft 531. Because the rotating shaft 531 is rotatably inserted into the damping member 533, the damping member 533 provides resistance, making the rotation of the knob 537 feel heavier, enhancing the user's feel. Both the damping member 533 and the pressing member 535 can be made of rubber.

[0041] like Figure 6 As shown, the adjustment mechanism 53 also includes a positioning member 538. The slider 51 is provided with a positioning hole 5141 that connects to the slide groove 510. After the slider 51 is mounted on the guide rod 21, the positioning member 538 is disposed in the positioning hole 5141. The positioning member 538 is used to secure the sliding assembly 50 to the guide rod 21. In this embodiment, the positioning hole 5141 can be a threaded hole formed on the left side wall 514 of the slider 51, which connects to the slide groove 510. The positioning member 538 can be a locking knob that includes a screw, such as a clevis screw, that is threaded into the threaded hole. After the sliding assembly 50 is moved into position on the guide rod 21, the clevis screw is tightened to press against the guide rod 21, thereby securing the sliding assembly 50 in its current position on the guide rod 21 and preventing further movement.

[0042] In other embodiments, the positioning hole 5141 can also be opened on the upper side wall 511, the lower side wall 512 or the right side wall 515 of the slider 51. It is only necessary for the positioning hole 5141 to be connected to the slide groove 510, and the positioning member 538 to be able to support the guide slide rod 21 after being set in the positioning hole 5141.

[0043] The slider 51 is also provided with at least one mounting hole 5143 connected to the slide groove 510. The adjustment mechanism 53 also includes an elastic member 539, and the elastic member 539 is installed in the mounting hole 5143. When the slider 51 is sleeved on the guide rod 21, the elastic member 539 elastically presses against the guide rod 21. As the slider 51 slides on the guide rod 21, a gap is left between the slider 51 and the guide rod 21. The elastic member 539 presses against the guide rod 21, which can reduce the gap between the slider 51 and the guide rod 21 and reduce the amplitude of the slider 51 shaking on the guide rod 21. At the same time, when the slider 51 moves, the elastic member 539 can increase friction to prevent the slider 51 from being accidentally pushed and moving due to the sliding assembly 50's own gravity. In this embodiment, the left side wall 514 of the slider 51 defines three mounting holes 5143 that connect to the chute 510. Each mounting hole 5143 houses an elastic member 539, specifically a plunger elastic screw. The three elastic members 539 collectively support the guide rod 21, forming a three-point plane and providing high stability.

[0044] The upper sidewall 511 of the slider 51 also defines a bracket mounting hole 5114. The bracket 55 includes a connecting rod 551 and a positioning frame 553 disposed at one end of the connecting rod 551. The connecting rod 551 is inserted into the bracket mounting hole 5114, and the positioning frame 553 is used to secure the interventional medical device. In this embodiment, the connecting rod 551 can be snapped into the bracket mounting hole 5114 or fixed thereto via screws or pins to facilitate replacement of different types of brackets 55. The positioning frame 553 can be a C-shaped frame, which facilitates positioning of the interventional medical device. Of course, the positioning frame 553 can also be a V-shaped frame, a U-shaped frame, or the like.

[0045] In other embodiments, the bracket 55 can also be directly welded to the upper side wall 511 or fixedly connected to the upper side wall 511 by bonding. The bracket 55 can be made of metal or plastic. The shape of the positioning frame 553 of the bracket 55 is compatible with the shape of the portion of the invasive medical device used for fixing.

[0046] Please also refer to Figure 6 、 Figure 9 and Figure 10When assembling the sliding assembly 50, first place the gear 530 in the gear mounting groove 5112 of the slider 51, and place the lap ring 5303 on the supporting surface 5113; then the first connecting section 5312 of the rotating shaft 531 passes through the second sub-accommodating groove 5185, the first sub-accommodating groove 5184 and the through hole 5181 in sequence, and is inserted into the connecting hole 5301 of the gear 530 and abuts against the blind hole 5182. The locking piece is inserted into the through hole 5305 of the rotating shaft 531 to lock it. The gear 530 is fixedly connected to the first connecting section 5312 in the first locking hole 5316 of the first connecting section 5312. At this time, the end of the first connecting section 5312 is accommodated in the blind hole 5182, and the boss 5315 is accommodated in the first sub-accommodating groove 5184 and abuts against the periphery of the through hole 5181; then the damping member 533 is sleeved on the second connecting section 5314 and abuts against the boss 5315, and the pressing member 535 is sleeved on the second connecting section 531 4 and accommodated in the second sub-accommodation groove 5185, the locking member 536 is inserted into the through hole 5351 and locked in the corresponding locking hole 5186; at this time, the second connecting section 5314 extends away from the end of the first connecting section 5312 and out of the outer side of the pressing member 535; then the knob 537 is mounted on the end of the second connecting section 5314, the locking member is inserted into the locking hole 5374 and locked in the second locking hole 5317 of the second connecting section 5314; finally, the sealing cover 5 17 is accommodated in the gear groove 5111 of the slider 51, and the locking member passes through the through hole 5172 and is locked in the corresponding locking hole; the screw of the positioning member 538 is screwed into the positioning hole 5141; a plurality of elastic members 539 are respectively installed in the corresponding mounting holes 5143 of the slider 51, so that the elastic supporting portion of the elastic member 539 extends into the slide groove 510; and then the connecting rod 551 of the bracket 55 is inserted into the bracket mounting hole 5114 of the slider 51.

[0047] When assembling the support device 100, the sliding assembly 50 is mounted on the guide rod 21. Specifically, the guide rod 21 slightly opens the opening 513 of the slider 51, allowing the guide rod 21 to pass through the opening 513 and be accommodated in the slide groove 510. This causes the gear 530 in the slider 511 to engage with the rack 210 of the guide rod 21, and the elastic member 539 to elastically support the guide rod 21. In this embodiment, three sliding assemblies 50 are movably mounted on the guide rod 21. By rotating the knob 537 of each sliding assembly 50, the rotating shaft 531 is rotated, which drives the gear 530 to engage and rotate on the rack 210, causing the sliding assembly 50 to move along the guide rod 21. When the sliding assembly 50 moves to a suitable position, the positioning member 538 is rotated to press against the guide rod 21 to position the sliding assembly 50 on the guide rod 21, and the elastic member 539 also elastically presses against the guide rod 21 to prevent the sliding assembly 50 from sliding relative to the guide rod 21.

[0048] In another embodiment, the rack 210 may be located on the back side 213 of the guide rod 21. In this case, the rack 210 is multi-segmented, and the rack 210 is not provided at the connection between the guide rod 21 and the connector 25. In this embodiment, the slider 51 in the illustrated embodiment is rotated 180 degrees vertically, and the upper sidewall of the slider 51 (the lower sidewall 512 of the slider 51 in the illustrated embodiment) is designed to be closed. The bracket 55 may be located on the upper sidewall of the slider 51, the knob 537 may be located on the left or right sidewall of the slider 51, the lower sidewall of the slider 51 may be provided with a slot 510, and the positioning member 538 and the elastic member 539 may be located on the right or left sidewall.

[0049] In another embodiment, the rack 210 can be located on the right side of the guide rod 21. In this case, the rack 210 is multi-segmented, and the rack 210 is not provided at the connection between the guide rod 21 and the connector 25. In this embodiment, the slider 51 in the illustrated embodiment is rotated 90 degrees to the right, and the left side wall of the slider 51 (the lower side wall 512 of the slider 51 in the illustrated embodiment) is designed to be closed. Of course, the left side wall can also retain the opening 212. The bracket 55 can be located on the upper side wall of the slider 51, the knob 537 can be located on the lower side wall of the slider 51, the right side wall can be provided with a gear mounting slot 5112, and the positioning member 538 and the elastic member 539 can be located on the upper side wall of the slider 51.

[0050] In yet another embodiment, the rack 210 can be located on the left side of the guide rod 21. In this case, the rack 210 can be a single piece. In this embodiment, the slider 51 in the illustrated embodiment is rotated 90 degrees to the left, and the lower sidewall of the slider 51 can be provided with an opening 212. The positioning member 538 and elastic member 539 can be located on the right sidewall, the bracket 55 and knob 537 can both be located on the upper sidewall of the slider 51, and the left sidewall can be provided with a gear mounting slot 5112.

[0051] It should be noted that in all embodiments of the present invention, the front side 211 of the guide slide bar 21 faces away from the substrate 23 and the back side 213 faces toward the substrate 23 ; the upper side wall of the slider 51 faces away from the substrate 23 and the lower side wall faces toward the substrate 23 .

[0052] See also Figure 11 The present invention also provides an interventional medical system. The interventional medical system includes an interventional medical device 300 and a support device 100, and the interventional medical device 300 is fixed on the bracket 55 of the support device 100. In this embodiment, the interventional medical device 300 is, for example, a mitral valve clip system. The mitral valve clip system includes a control handle 310, a bending adjustment sheath 320 and a guide sheath 330 in sequence. The control handle 310, the bending adjustment sheath 320 and the guide sheath 330 can move relative to each other in pairs. Three sliding assemblies 50 are sleeved on the guide slide rod 21 of the support device 100, and the brackets 55 of the three sliding assemblies 50 are used to fix the control handle 310, the bending adjustment sheath 320 and the guide sheath 330 respectively.

[0053] When in use, the control handle 310, the bending adjustment sheath 320 and the guide sheath 330 are respectively installed on the brackets 55 of the three sliding components 50, and the positioning piece 538 of the sliding component 50 is loosened to disengage the positioning piece 538 from the abutment against the guide rod 21; by rotating the knob 537 of the sliding component 50, the rotating shaft 531 is driven to rotate, so as to drive the corresponding gear 530 to rotate and engage with the rack 210, so that the sliding component 50 moves relative to the guide rod 21, and the control handle 310, the bending adjustment sheath 320 and / or the guide sheath 330 move along the guide rod 21 with the corresponding sliding component 50 until the various parts of the interventional medical device 300 move to the appropriate position, and then the positioning piece 538 is tightened. Through the engagement of the gear 530 and the rack 210, each sliding component 50 can move along the guide rod 21. The rotation amount of the control gear 530 can adjust the movement amount of the sliding component 50, avoiding excessive movement of the sliding component 50 or improper movement of the sliding component 50 during the operation, ensuring the smooth progress of the operation, reducing surgical risks, and facilitating regulation.

[0054] Since the sliding assembly 50 can be detachably mounted on the guide rod 21, the number of sliding assemblies 50 on the guide rod 21 can be determined according to the portion of the interventional medical device 300 that needs to be fixed. For example, if the interventional medical device 300 includes a control handle 310, then only one sliding assembly 50 needs to be mounted on the guide rod 21 of the support device 100, and the control handle 310 can be detachably fixed to the bracket 55. For another example, if the interventional medical device 300 includes a control handle 310 and a bending adjustment sheath 320, or includes a control handle 310 and a guide sheath 330, then two sliding assemblies 50 need to be mounted on the guide rod 21 of the support device 100, and the control handle 310 and the bending adjustment sheath 320 can be detachably fixed to the brackets 55 of the two sliding assemblies 50, or the control handle 310 and the guide sheath 330 can be detachably fixed to the brackets 55 of the two sliding assemblies 50.

[0055] In other embodiments, if the interventional medical device 300 includes four or more parts, four or more sliding components 50 need to be mounted on the guide rod 21 of the support device 100, and the four or more parts can be detachably fixed to the brackets 55 of the corresponding sliding components 50.

[0056] Please also refer to Figure 12 and Figure 13 The interventional medical system also includes an adjustment table 400. The adjustment table 400 includes a support plate 410 and an adjustment mechanism 420. The support device 100 is mounted on the support plate 410. The base plate 23 of the support frame 20 and the support plate 410 can be fixed together by friction, or by means of a snap connection, screw connection, or adhesive connection. The adjustment mechanism 420 is used to adjust the inclination of the support plate 410.

[0057] In this embodiment, the substrate 23 and the support plate 410 are fixed by friction. Preferably, an anti-slip member such as a silicone pad is provided between the support plate 410 and the substrate 23 to increase the friction between the substrate 23 and the support plate 410; specifically, the anti-slip member is attached to the front side of the support plate 410 or to the back side of the substrate 23.

[0058] The control table 400 also includes a base plate 430. An adjustment mechanism 420 is disposed between the base plate 430 and the support plate 410. The adjustment mechanism 420 is used to adjust the angle of the support plate 410 relative to the base plate 430, thereby adjusting the angle of the support device 100 to achieve an appropriate puncture angle for the interventional medical device 300 fixed to the support device 100. The adjustment mechanism 420 includes a support column 421 and an adjustment member 423 disposed between the support column 421 and the support plate 410. The support plate 410 is hinged to the end of the support column 421 away from the base plate 430. The adjustment member 423 is used to adjust the rotation of the support plate 410 relative to the support column 421 and to position the rotation of the support plate 410 and the support column 421. Specifically, after the support plate 410 rotates to the appropriate angle relative to the support column 421, the adjustment member 423 positions the support plate 410 and the support column 421 to prevent the support plate 410 from rotating relative to the support column 421.

[0059] In this embodiment, the adjustable angle range of the support plate 410 relative to the bottom plate 430 (ie, the horizontal plane) is 0 degrees to 30 degrees. Figure 12 As shown, the angle of the support plate 410 of the control table 400 relative to the flat water surface is 0 degrees; Figure 13 As shown, the angle of the support plate 410 of the control table 400 relative to the flat water surface is 30 degrees.

[0060] Of course, the supporting device 100 itself has an inclination angle. In the case that there is no need to further adjust the puncture angle of the invasive medical device 300 , the supporting device 100 can be directly placed on a platform.

[0061] The above is an implementation of the embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
