Furthermore, in the context, it should also be understood that when it is mentioned that an element is formed "upper" or "lower" of another element, it can not only be formed directly "upper" or "lower" of the other element, but also indirectly "upper" or "lower" of the other element through an intermediate element.

[0049] Figure 1 This schematic diagram illustrates the structure of a surgical delivery device support frame according to one embodiment of the present invention, as shown below. Figure 1 As shown, a surgical delivery device support frame of this utility model includes:

[0050] Support device 10, first drive device 20, and second drive device 30;

[0051] The support device 10 includes a base 101 and a support frame 102. One end of the support frame 102 is rotatably connected to the base 101. The second drive device 30 is disposed on the support frame 102. The support frame 102 is used to place the surgical delivery device 40. The second drive device 30 is used to fix and axially move the surgical delivery device 40.

[0052] The first driving device 20 is mounted on the base 101. The first driving device 20 includes a first axial moving structure 201 and a sliding bracket 202. The first end of the sliding bracket 202 is rotatably connected to the bottom of the support frame 102, and the second end is rotatably connected to the first axial moving structure 201. The sliding bracket 202 is used to support the support frame 102. The first axial moving structure 201 is used to drive the second end of the sliding bracket 202 to move axially, so that the first end adjusts the tilt angle of the support frame 102 relative to the base 101.

[0053] With this configuration, by mounting the surgical delivery device 40 on the support frame 102, the second drive device 30 can drive the surgical delivery device 40 to move axially, while the first drive device 20 can drive the support frame 102 to change the tilt angle so that the orientation of the end of the surgical delivery device 40 changes. By supporting and moving the surgical delivery device 40 through the device, the doctor's burden is reduced and the work efficiency is improved.

[0054] Furthermore, Figure 2 This diagram schematically illustrates the structure of the second axial movement structure according to one embodiment of the present invention. Figure 3 This schematic diagram illustrates the structure of the third axial movement structure according to one embodiment of the present invention. Figure 4 This schematic diagram illustrates the structure of the first fixing member according to one embodiment of the present invention, as shown below. Figures 2-4 As shown:

[0055] The second drive device 30 includes a second axial movement structure 301 and a third axial movement structure 302;

[0056] The second axial moving structure 301 is slidably connected to the support frame 102, and the third axial moving structure 302 is slidably connected to the second axial moving structure 301.

[0057] The surgical delivery device 40 includes a first housing 401 and a second housing 402, the first housing 401 and the second housing 402 are slidably connected, a second axial moving structure 301 is fixedly connected to the first housing 401, and a third axial moving structure 302 is fixedly connected to the second housing. The second axial moving structure 301 is used to control the axial movement of the surgical delivery device 40, and the third axial moving structure 302 is used to control the axial movement of the second housing 402 relative to the first housing 401.

[0058] Specifically, the second axial moving structure 301 includes a first slider 3011, a first fixing member 3012, and a first handle 3013. The first slider 3011 is disposed on the top of the support frame 102 and is slidably connected to the support frame 102. The first fixing member 3012 is fixedly connected to the top of the first slider 3011 and is used for the surgical delivery device 40 to pass through and be fixedly connected to the surgical delivery device 40.

[0059] like Figure 4 As shown, the first fixing member 3012 includes a first collar 30121 and a second collar 30122. The first collar 30121 is fixedly connected to the first slider 3011. One end of the second collar 30122 is rotatably connected to one end of the first collar 30121. A fifth limiting member 30123 is provided on the side wall of the other end of the first collar 30121. A limiting block 30124 is provided on the side wall of the other end of the second collar 30122. When the limiting block 30124 is located in the fifth limiting member 30123, the first collar 30121 and the second collar 30122 together clamp the surgical delivery device 40.

[0060] After the surgical delivery device 40 is placed on the first ring 30121, the second ring 30122 is rotated so that the second ring 30122 and the first ring 30121 together clamp the surgical delivery device 40. At the same time, the limiting block 30124 is inserted into the fifth limiting member 30123 and is restricted from moving by the fifth limiting member 30123, thus locking the second ring 30122 and fixing the surgical delivery device 40.

[0061] Furthermore, the fifth limiting member 30123 is installed in the fixing groove 30125 on the side wall of the first collar 30121. The two sides of the fifth limiting member 30123 are rotatably connected to the fixing groove 30125, and an elastic element (not shown in the figure), such as a spring, is provided at its rotatable connection. The elastic element has a preload force to make the fifth limiting member 30123 rotate closer to the second collar 30122. A limiting groove 30126 is provided on the surface of the fifth limiting member 30123 facing the second collar 30122. The limiting groove 30126 has the same shape as the limiting block 30124. When the second collar 30122 approaches the first collar 30121, a limiting groove 30126 is provided. When ring 30121 rotates, the end of the fifth limiting member 30123 is controlled to rotate away from the second ring 30122, so that the limiting block 30124 can enter the area of ​​the limiting groove 30126. At this time, the fifth limiting member 30123 is no longer pressed, so that the fifth limiting member 30123 is automatically rotated towards the second ring 30122 by the action of the elastic member, so that the limiting block 30124 enters the limiting groove 30126 and is restricted in movement by the limiting groove 30126. In this way, the second ring 30122 and the first ring 30121 jointly clamp the surgical delivery device 40.

[0062] Furthermore, a through first groove (not shown in the figure) is provided at the bottom of the support frame 102, and a fixed bracket 1021 is provided outside the first groove. The fixed bracket 1021 is fixedly connected to the support frame 102, and the first rotating shaft (not shown in the figure) of the first handle 3013 passes through the fixed bracket 1021 and is rotatably connected to the fixed bracket 1021.

[0063] A first gear 3014 is sleeved on the side wall of the first rotating shaft. The first gear 3014 can pass through the first groove and mesh with the bottom plane of the first slider 3011. When the first handle 3013 rotates, the first slider 3011 moves axially relative to the support frame 102, thereby driving the first fixing member 3012 and the surgical delivery device 40 on it to move synchronously.

[0064] Furthermore, the third axial moving structure 302 includes a second slider 3021, a second fixing member 3022, and a second handle 3023. The second slider 3021 is disposed on top of the first slider 3011 and is slidably connected to the first slider 3011. The second fixing member 3022 is fixedly connected to the second slider 3021 and has the same structure as the first fixing member 3012. The second fixing member 3022 is used for the second housing 402 to pass through and is fixedly connected to the second housing 402.

[0065] The second shaft of the second handle 3023 (not shown in the figure) passes through the second slider 3021, and the second handle 3023 is rotatably connected to the second slider 3021. The side wall of the first shaft is fitted with a second gear 3024, which meshes with the top plane of the first slider 3011. When the second handle 3023 rotates, the second slider 3021 moves axially relative to the first slider 3011, thereby driving the second fixing member 3022 and the second housing 402 on it to move synchronously.

[0066] Furthermore, racks 30111 are provided on the top and bottom surfaces of the first slider 3011. A first gear 3014 meshes with the rack 30111 at the bottom of the first slider 3011, and a second gear 3024 meshes with the rack 30111 at the top of the first slider 3011. When the first handle 3013 rotates, the first slider 3011 can move axially through the rack meshing, thereby driving the third axial moving structure 302 on it to move synchronously. When the second handle 3023 rotates, the second slider 3021 moves axially through the rack meshing, and the first slider 3011 remains stationary.

[0067] Meanwhile, the length of the first slider 3011 is less than the length of the support frame 102, and the length of the second slider 3021 is less than the length of the first slider 3011, so that the first slider 3011 can move a certain distance relative to the support frame 102, and the second slider 3021 can move a certain distance relative to the first slider 3011.

[0068] Furthermore, Figure 5 This diagram schematically illustrates the structure of the first axial moving structure according to one embodiment of the present invention. Figure 6 This schematic diagram illustrates the internal structure of the third fastener according to one embodiment of the present invention, as shown below. Figure 5 , 6 As shown:

[0069] The first axial moving structure 201 includes a third slider 2011, a third fixing member 2012, and a third handle 2013;

[0070] The third fixing member 2012 is fixedly connected to the top of the base 101, and the third rotating shaft 20131 of the third handle 2013 is axially inserted into the third fixing member 2012, and the third handle 2013 is rotatably connected to the third fixing member 2012.

[0071] A through first slide groove 20121 is provided on the side wall of the third fixing member 2012. The third slider 2011 can extend into the third fixing member 2012 through the first slide groove 20121 and be rotatably connected to the third rotating shaft 20131. The third slider 2011 is slidably connected to the first slide groove 20121.

[0072] Specifically, the third slider 2011 is threadedly connected to the third rotating shaft 20131. When the third handle 2013 controls the third rotating shaft 20131 to rotate, the third slider 2011 moves axially because it is slidably connected to the first slide groove 20121.

[0073] When the third slider 2011 is controlled to move toward the support frame 102, since the third slider 2011 is fixedly connected to the second end of the sliding bracket 202, the second end of the sliding bracket 202 is driven to move synchronously. Since the length of the sliding bracket 202 remains unchanged, when the second end of the sliding bracket 202 moves toward the support frame 102, its first end will be raised, thereby increasing the tilt angle of the support frame 102 and realizing the angle adjustment of the surgical delivery device 40.

[0074] Furthermore, the sliding bracket 202 is detachably connected to the support frame 102 and the first axial moving structure 201;

[0075] Multiple sliding brackets 202 are provided, and the multiple sliding brackets 202 have different lengths. The multiple sliding brackets 202 with different lengths are used to make the support frame 102 have different tilt angle ranges.

[0076] When assembling the surgical delivery support frame, one of the sliding supports 202 is installed between the support frame 102 and the first axial movement structure 201.

[0077] With this configuration, sliding brackets 202 of different lengths can be replaced to connect between the support frame 102 and the first axial moving structure 201 according to different usage requirements, thereby achieving different tilt angle ranges for the support frame 102, so that the end of the surgical delivery device 40 has a wider range of intervention angles.

[0078] Furthermore, such as Figure 2 , 3 As shown, a first limiting hole (not shown in the figure) is provided on the side wall of the support frame 102. The first limiting member 3015 can pass through the first limiting hole and abut against the first slider 3011 to lock the movement of the first slider 3011 relative to the support frame 102.

[0079] A second limiting hole (not shown in the figure) is provided on the side wall of the second slider 3021. The second limiting member 3025 can pass through the second limiting hole and abut against the first slider 3011 to lock the movement of the second slider 3021 relative to the first slider 3011.

[0080] With this configuration, once the first slider 3011 is in place, it can be locked to the support frame 102 by the first limiting member 3015, thereby fixing the surgical delivery device 40 and preventing the surgical delivery device 40 from sliding due to its own weight or external factors, which would affect the interventional surgical treatment.

[0081] Similarly, when the second slider 3021 moves into place, the second limiting member 3025 locks the second slider 3021 and the first slider 3011 together, thereby fixing the second housing 402 and preventing the second housing 402 from sliding due to its own weight or external factors, which would affect the interventional surgery.

[0082] Furthermore, a second sliding groove 20122 is provided on the side wall of the third fixing member 2012, and the second sliding groove 20122 is parallel to the first sliding groove 20121.

[0083] A third limiting hole (not shown in the figure) is provided on the side wall of the third slider 2011. The third limiting member 2014 can pass through the second slide groove 20122 and be inserted into the third limiting hole. The third limiting member 2014 is used to lock the movement of the third slider 2011 relative to the third fixing member 2012.

[0084] The third limiting member 2014 is slidably connected to the second slide groove 20122.

[0085] Specifically, the third limiting member 2014 is threadedly connected to the third limiting hole. When the third limiting member 2014 is screwed in, it abuts against the third fixing member 2012, thereby realizing the locking operation between the third slider 2011 and the third fixing member 2012.

[0086] Meanwhile, when not locked, the end of the third limiting member 2014 can still be partially inserted into the third limiting hole for storage, avoiding the problem of loss after the third limiting member 2014 is disassembled separately.

[0087] Furthermore, such as Figure 1 As shown, a through second groove 501 is provided on the side wall of the support frame 102 and the second slider 3021, and a damping plate 502 is provided in the second groove 501. The damping plate 502 abuts against the first slider 3011.

[0088] A fourth limiting member 503 is provided on the outside of the damping plate 502. The fourth limiting member 503 abuts against the damping plate 502. The fourth limiting member 503 is used to control the magnitude of its abutment force with the damping plate 502 in order to control the magnitude of the friction force between the first slider 3011 and the support frame 102, and between the second slider 3021 and the first slider 3011.

[0089] With this setup, the two movement modes of the surgical delivery device 40, coarse adjustment and fine adjustment, are achieved by increasing friction through the damping plate 502.

[0090] Furthermore, the support frame 102 is detachably connected to the base 101, and the sliding bracket 202 is detachably connected to the support frame 102 and the first axial moving structure 201, reducing the overall device volume for easy storage.

[0091] In summary, according to the present invention, the first driving device 20 includes a first axial moving structure 201 and a sliding bracket 202. The sliding bracket 202 is connected to the support frame 102 and the first axial moving structure 201 at both ends. The first axial moving structure 201 can drive one end of the sliding bracket 202 to move axially to adjust the angle of the sliding bracket 202, thereby controlling the tilt angle of the support frame 102. The second driving device 30 is set on the support frame 102, and the surgical delivery device 40 is placed on the support frame 102. The second driving device 30 can control the axial movement of the surgical delivery device 40 to achieve multi-angle and multi-position control of the surgical delivery device 40.
