[0002] During interventional medical procedures, in order to ensure the safety and smooth progress of the surgery, it is often necessary to keep the medical device in a certain position. For example, part of the medical device must be positioned near the patient's body or near the surgical site during the medical procedure. Therefore, various auxiliary support devices can be used to stabilize and position the medical device.

[0003] Generally, during surgery, medical equipment needs to be manipulated and repositioned. In many cases, one part of the invasive medical equipment must be moved relative to another part. Prior art, such as the patent with publication number CN114052985A, discloses a support device and an invasive medical system. The positions of each sliding unit in the solution can only be adjusted independently, and the combined adjustment and pushing of the positions of multiple sliding units cannot be achieved, resulting in a low adjustment efficiency of the invasive medical equipment.

[0005] In a first aspect, an embodiment of the present application provides a support device, which is used to fix an interventional medical device. The support device includes a support frame and a plurality of bracket units, and the support frame includes a first guide rod; the plurality of bracket units are spaced apart along the length direction of the first guide rod, and each bracket unit has a bracket for connecting to the interventional medical device; wherein the support device also includes a second guide rod, which is slidably mounted on the first guide rod along its length direction; at least one of the plurality of bracket units is arranged on the first guide rod, at least two of the plurality of bracket units are arranged on the second guide rod, and at least one of the plurality of bracket units located on the second guide rod is movably arranged on the second guide rod.

[0051] The present application embodiment provides a support device, please refer to Figure 1 and Figure 2The support device 100 is used to fix the interventional medical device. The support device 100 includes a support frame 10 and a plurality of bracket units 20. The support frame 10 includes a first guide rod 11. The plurality of bracket units 20 are spaced apart along the length direction of the first guide rod 11, and each bracket unit 20 has a bracket 24 for connecting with the interventional medical device. The support device also includes a second guide rod 12, which is slidably mounted on the first guide rod 11 along its length direction.

[0052] In this solution, the interventional medical device is explained by taking the catheter delivery system as an example. The support frame 10 serves as the bearing body, and multiple bracket units 20 are arranged at intervals on the first guide rod 11 of the support frame 10. The multiple bracket units 20 can complete the support and positioning of multiple handles in the catheter delivery system. The second guide rod 12 is slidably mounted on the first guide rod 11 along its length direction, at least one of the multiple bracket units 20 is arranged on the first guide rod 11, and at least two of the multiple bracket units 20 are arranged on the second guide rod 12, and at least one of the multiple bracket units 20 located on the second guide rod 12 is movably arranged on the second guide rod 12, so that when the position of the multiple bracket units 20 located on the second guide rod 12 needs to be adjusted, the relative position of the second guide rod 12 on the first guide rod 11 can be adjusted, so that the multiple bracket units 20 on the second guide rod 12 can be driven to slide along with the second guide rod 12, thereby realizing the synchronous combined pushing of the multiple bracket units 20 on the second guide rod 12; when the position of the bracket unit 20 on the second guide rod 12 needs to be adjusted separately, at least one of the bracket units 20 on the second guide rod 12 can slide on the second guide rod 12, thereby realizing the separate adjustment of the bracket unit 20 on the second guide rod 12. Therefore, compared with the prior art in which the handles in the transcatheter delivery system can only be pushed individually, the multiple bracket units 20 on the support device in this solution can realize the combined pushing or individual pushing of the multiple handles of the transcatheter delivery system according to the actual usage scenario, thereby solving the problem of the long pushing time caused by the need to adjust the handles of the transcatheter delivery system in the prior art one by one, and the pushing efficiency of the handles in the transcatheter delivery system is higher.

The number of the bracket units 20 is set to three, and the three bracket units 20 are respectively the first bracket unit 21, the second bracket unit 22 and the third bracket unit 23. The first bracket unit 21 is fixedly or slidably arranged on the first guide rod 11, and the second bracket unit 22 and the third bracket unit 23 are both arranged on the second guide rod 12, and the third bracket unit 23 is slidably arranged on the second guide rod 12.

[0074] Optionally, there are two limit blocks 54 , and the two limit blocks 54 are respectively located on both sides of the slide plate 14 in the length direction.

[0075] In addition, a mounting column 55 is provided on the base 13 , and the rocker 51 is sleeved on the mounting column 55 and limited by a retaining ring 56 , which restricts the rocker 51 from being separated from the rotating column.

[0076] In some embodiments, see Figure 7 and Figure 8 , the two support rods are respectively the first support rod 15 and the second support rod 16, the length of the first support rod 15 is less than the length of the second support rod 16, one end of the first guide rod 11 is hinged to the first support rod 15, and the other end of the first guide rod 11 is slidably disposed on the second support rod 16, so that the inclination angle of the first guide rod 11 is adjustable. Due to individual differences and the influence of the height of the device platform, the transcatheter delivery system in the interventional medical system cannot guarantee the incision angle, and the other end of the first guide rod 11 is slidably disposed on the second support rod 16, and the other end of the first guide rod 11 is driven on the second support rod 16, so that the inclination angle of the first guide rod 11 can be adjusted. It is convenient for doctors to adjust the angle of the transcatheter delivery system.

[0077] Among them, one end of the first guide rod 11 is rotatably installed on the top end of the first support rod 15 through a hinge, and the other end of the first guide rod 11 is passed through the second support rod 16, and the first guide rod 11 can slide relative to the height direction of the second support rod so that the inclination angle of the first guide rod 11 is adjustable.

[0078] The lower ends of the first support rod 15 and the second support rod 16 are fixed to the slide plate 14 by bolts 17 .

[0079] In some embodiments, please refer to Figure 7 and Figure 8 An angle adjustment component 60 for adjusting the inclination angle of the first guide rod 11 is provided between the first guide rod 11 and the second support rod 16; the angle adjustment component 60 includes a fourth slider 61 and a third locking knob 62, the second support rod 16 is provided with a sliding hole 161 along its vertical direction, and the fourth slider 61 can be slidably arranged in the sliding hole 161; the fourth slider 61 is provided with a first clearance hole 611 for the first guide rod 11 to pass through, the fourth slider 61 has a threaded hole 612, the third locking knob 62 is threadedly matched with the threaded hole 612, and the threaded hole 612 is communicated with the first clearance hole 611, so that one end of the third locking knob can be against the first guide rod 11, and the first guide rod 11 is pressed against the side wall of the second support rod 16; the second support rod 16 is correspondingly provided with a second clearance hole 162 for the first guide rod 11 to extend out, and the second clearance hole 162 is communicated with the sliding hole 161.

[0080] The second support rod 16 is correspondingly provided with a second clearance hole 162 for the first guide rod 11 to extend out, that is, the first guide rod 11 passes through the sliding hole 161 of the second support rod 16, and the fourth sliding block 61 is provided with a first clearance hole 611 for the first guide rod 11 to pass through. The third locking knob 62 is threadedly matched with the threaded hole 612 on the fourth sliding block. By rotating the third locking knob 62 forwards and backwards, the fourth sliding block 61 can be moved or locked in the direction of the sliding hole 161 in the second support rod 16. When the angle of the first guide rod 11 needs to be adjusted, the third locking knob 62 is loosened, and the fourth sliding block 61 can slide in the sliding hole 161 of the second support rod 16. When the angle of the first guide rod 11 is adjusted to the right position, the third locking knob is tightened, and the third locking knob 62 presses the first guide rod 11 against the side wall of the second support rod 16, thereby preventing the fourth sliding block 61 from sliding.

[0081] Among them, the sliding hole 161 on the second support rod 16 passes through the top of the second support rod 16, which is convenient for the assembly of the fourth slider 61. The top cover of the second support rod 16 is provided with a cap 163, which is used to close the sliding hole 161 and prevent the fourth slider 61 from sliding out of the sliding hole 161.

[0082] In some embodiments, for the bracket 24 in the bracket unit 20, see Figure 3 The bracket 24 includes a main body 241 for supporting the interventional medical device and an elastic positioning mechanism 242 . The elastic positioning mechanism 242 is disposed on the main body 241 , and is used to provide a resisting positioning force to the interventional medical device.

[0083] The number of the elastic positioning mechanisms 242 can be set to be multiple, and the multiple elastic positioning mechanisms 242 are spaced along the axial direction and / or circumferential direction of the body 241. The multiple elastic positioning mechanisms 242 can cooperate with each other to perform multi-point positioning on the handle of the interventional medical device, and the multiple points can be spaced along the axial direction and / or circumferential direction of the body 241. The multiple elastic positioning mechanisms 242 have higher positioning stability for the handle on the bracket 24, and the handle of the interventional medical device is not easy to loosen or deviate during operation, ensuring the normal operation of the operation.

[0084] In this embodiment, the number of the elastic positioning mechanisms 242 is four, and the four elastic positioning mechanisms 242 are divided into two groups of elastic positioning mechanisms 242, each group of elastic positioning mechanisms 242 includes two elastic positioning mechanisms 242; the two groups of elastic positioning mechanisms 242 are respectively located on two opposite sides of the main body 241 in the circumferential direction, and the two elastic positioning mechanisms 242 of each group of elastic positioning mechanisms 242 are distributed at intervals along the axial direction of the main body 241.

[0085] The elastic positioning mechanism 242 includes an elastic member and a positioning bead 2421. The elastic member is disposed in the body 241. The body 241 has a first surface 2411 facing the side of the interventional medical device. The elastic member is used to provide elastic force to the positioning bead 2421 so that the positioning bead 2421 can protrude from the first surface 2411. The elastic member provides elastic force to the positioning bead 2421, and the positioning bead 2421 protrudes from the first surface 2411 of the body 241. The handle on the bracket 24 can squeeze the positioning bead 2421, so that the elastic member accumulates elastic potential energy after being compressed. Under the reaction force of the positioning bead 2421, the positioning and holding function can be provided to the handle in the interventional medical device, thereby realizing the self-positioning function of the handle on the bracket 24. And because the positioning bead 2421 has a spherical structure, when the positioning bead 2421 contacts the handle of the interventional medical device, it is a point contact, and the contact area between the positioning bead 2421 and the handle is small, which makes it easy for the operator to rotate the handle to squeeze the positioning bead 2421 to adjust the angle, and also reduces the probability of the positioning bead 2421 causing indentations on the appearance of the handle.

[0086] The embodiment of the present application further provides an interventional medical system, which includes an interventional medical device and a support device 100 of any of the aforementioned embodiments. The interventional medical device includes a handle, and the bracket 24 is used to fix the handle.
