When the rotating shaft 3341 rotates to drive the gear 3342 to mesh with the rack 362 and rotate and move along the rack 362, the fastening structure is also driven to rotate so that it tends to move along the length direction of the bracket slot 36, and a thrust is generated on the slot connection block 331 along the length direction of the bracket slot 36, so that the sliding member 33 moves along the length direction of the bracket slot 36. The fastening structure can prevent the gear 3342 from generating axial displacement when rotating, so that when the slot connection block 331 slides along the bracket slot 36, it will not shake due to the axial displacement of the gear, that is, the movement of the sliding member 33 is more stable. In some embodiments, the fastening structure can be a fastening nut, one end of which contacts the end face of the gear 3342, and the other end is matched with the accommodating space gap.

[0062] Specifically, a limiting structure 3343 is provided on the rotating shaft 3341, and a first limiting matching structure 3311 is provided on the slideway connecting block 331. The first limiting matching structure 3311 cooperates with the limiting structure 3343 to limit the axial movement of the rotating shaft 3341, improves the sliding stability of the slideway connecting block 331, and further improves the stability of the synchronous movement of the middle tube bracket 34 and the control part bracket 35 driven by the sliding member 33. In some embodiments, the limiting structure 3343 is a groove structure integrally formed with the rotating shaft 3341, and the slideway connecting block 331 is provided with a protrusion structure that matches the groove structure; in other embodiments, the limiting structure 3343 is a protrusion structure integrally formed with the rotating shaft 3341 or fixedly sleeved on the rotating shaft 3341, and the slideway connecting block 331 is provided with a groove structure that matches the protrusion structure.

[0063] Further, a detachable limiting cover plate 336 is provided on one side of the slide connection block 331, and a connecting hole 3361 communicating with the through hole 335 is provided on the limiting cover plate 336, and a second limiting matching structure 3362 is provided on the limiting cover plate 336, and the second limiting matching structure 3362 cooperates with the limiting structure 3343 to limit the axial movement of the rotating shaft 3341. In some embodiments, the second limiting matching structure 3362 is a groove structure or a protrusion structure that can cooperate with the limiting structure 3343 to limit the position.

[0064] In this embodiment, a protruding limiting structure 3343 is provided on the rotating shaft 3341, a first limiting matching structure 3311 is provided on the slideway connecting block 331, and a second limiting matching structure 3362 is provided on the limiting cover plate 336. The two protruding side surfaces of the limiting structure 3343 are limited between the opposite inner surfaces of the first limiting matching structure 3311 and the second limiting matching structure 3362 to limit the axial displacement of the rotating shaft 3341. In some embodiments, a washer is provided on the side of the limiting structure 3343 facing the limiting cover plate 336 to facilitate the matching installation of the rotating shaft 3341 with the slideway connecting block 331 and the limiting cover plate.

[0065] In some embodiments, the slide member 33 is provided with an indication structure 330, and the indication structure 330 is used to indicate the position information of the sliding bracket assembly 32 on the displacement mark 30. In some embodiments, the indication structure 330 can be an indication arrow engraved, drawn or pasted on the slide connection block 331 or the limit cover plate 336, and the indication arrow is relative to the scale value on the displacement mark 30 to accurately indicate the position information of the sliding bracket assembly 32 on the displacement mark 30.

[0066] Specifically, the support device 300 includes a support mechanism 4, the support mechanism 4 includes a base 41 and a support assembly 42 fixed on the base 41, and the support body 3 is tilted relative to the base 41 and arranged on the support assembly 42. The support slot 36 of the support body 3 of this embodiment includes a slot bottom surface away from the base 41, a lower surface facing the base 41, and two opposite side surfaces, a rack 362 is arranged on the slot bottom surface, the support assembly 42 is fixedly connected to the lower surface, and the displacement mark 30 is arranged on the two side surfaces or one of the two.

[0067] Specifically, the support assembly 42 includes a first support 43, a second support 44 and a rotating assembly 45, wherein the rotating assembly 45 includes a rotating shaft 451 and a first connecting member 452 and a second connecting member 453 connected to the rotating shaft 451, wherein the first connecting member 452 is fixedly connected to the first support 43, and the second connecting member 453 is loosely matched with the second support 44; when the rotating shaft 451 rotates so that the first connecting member 452 is locked and fixed relative to the second connecting member 453, the second support 44 is fixed relative to the first support 43; when the rotating shaft 451 rotates so that the first connecting member 452 is separated relative to the second connecting member 453, the second support 44 can rotate relative to the first support 43. The support assembly 42 of the present application can support and accurately realize different approach angles of the interventional delivery device 200.

[0068] In some embodiments, the first connecting member 452 and the second connecting member 453 are matched first end face gears and second end face gears. The rotating assembly 45 includes a rotating shaft 451, a first end face gear, a second end face gear and an elastic member, wherein the first end face gear and the second end face gear are sleeved on the rotating shaft facing each other; the first end face gear is fixedly connected to the first pillar 43, the second end face gear is loosely matched with the second pillar 44, and the elastic member 454 is arranged between the second end face gear and the second pillar 44. When the rotating shaft 451 rotates clockwise to tighten the first end face gear and the second end face gear to mesh, the second pillar 44 is locked and fixed relative to the first pillar 43; when the rotating shaft 45 is loosened counterclockwise, the first end face gear and the second end face gear are separated due to the opposite force of the elastic member, so that the second pillar 44 can be rotated to achieve different angle positions. The support assembly 42 in the support device engages and disengages with each other through two end gears, thereby driving the second support 44 to rotate at different angles. Through a certain resilience of the elastic member, the end gears make a friction sound when rotating against each other, giving the doctor audible feedback.

[0069] In other embodiments, the rotating assembly can be realized by different rotating structures, including gear structures, slot synchronous rotation structures, etc.; the gear structure can be a planetary gear structure, which drives the peripheral small gears to rotate by rotating the central main gear, thereby rotating the outer ring large gear to rotate synchronously to achieve angular rotation; it can also be a bevel gear structure, which drives the driven bevel gear to rotate by rotating the rotating shaft and the active bevel gear, thereby achieving angle adjustment of the pillar assembly; the slot synchronous rotation structure can include a main rotating shaft and a driven rotating shaft, the two rotating shafts move coaxially, and are fixedly connected by a mechanical structure such as a slot to make the two rotating shafts rotate synchronously, thereby achieving angular rotation.

[0070] The present application supports and positions the middle tube assembly and the control assembly through a sliding bracket assembly, so that the middle tube assembly and the control assembly can move synchronously, thereby improving the stability and accuracy of the delivery of the valve clamping device at the distal end of the control assembly. The sliding rod and the movable bracket are provided so that the control assembly and the middle tube assembly can move relative to each other, which is convenient for adjusting and operating the interventional delivery device. By measuring the moving distance of the sliding bracket assembly relative to the fixed bracket, the moving distance of the middle tube assembly and the control assembly relative to the guide catheter assembly can be measured, so that when the medical intervention system of the present application is used for surgery, the valve clamping device at the distal end of the control assembly can be delivered to the target position without using DSA. The sliding part of the sliding bracket assembly improves its sliding stability by providing structures such as connecting groove structures and limit cover plates on both sides of the slide groove connecting block, thereby improving the adjustment accuracy of the interventional delivery device.
