[0019] Figure 1 A schematic diagram schematically shows the structure of a surgical conveyor support assembly according to an embodiment of the present invention, as shown in FIG. Figure 1 As shown, a surgical conveyor support assembly of the present invention comprises: A supporting device 10, a first driving device 20 and a second driving device 30; 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 arranged on the support frame 102, the support frame 102 is used to place the surgical conveyor 40, and the second drive device 30 is used to fix and axially move the surgical conveyor 40; The first driving device 20 is arranged on the base 101, and 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, and the first axial moving structure 201 is used to drive the second end of the sliding bracket 202 to axially move so that the first end adjusts the inclination angle of the support frame 102 relative to the base 101.

[0020] In this arrangement, by installing the surgical conveyor 40 on the support frame 102, the second drive device 30 can drive the surgical conveyor 40 to move axially, and the first drive device 20 can drive the support frame 102 to change the inclination angle to change the orientation of the end of the surgical conveyor 40.

[0021] Further, Figure 2 A schematic diagram schematically shows the structure of the second axial movement structure of an embodiment of the present invention, Figure 3 A schematic diagram schematically shows the structure of the third axial movement structure of an embodiment of the present invention, as shown in FIG. Figure 2 , 3 As shown: The second driving device 30 includes a second axial moving structure 301 and a third axial moving structure 302; The second axial movable structure 301 is slidably connected to the support frame 102, and the third axial movable structure 302 is slidably connected to the second axial movable structure 301; The surgical conveyor 40 includes a first shell 401 and a second shell 402, the first shell 401 is slidably connected to the second shell 402, the second axial moving structure 301 is fixedly connected to the first shell 401, and the third axial moving structure 302 is fixedly connected to the second shell. The second axial moving structure 301 is used to control the axial movement of the surgical conveyor 40, and the third axial moving structure 302 is used to control the axial movement of the second shell 402 relative to the first shell 401.

[0022] 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 arranged on the top of the support frame 102. The first slider 3011 is slidably connected to the support frame 102. The first fixing member 3012 is fixedly connected to the top of the first slider 3011. The first fixing member 3012 is used for the surgical conveyor 40 to pass through and is fixedly connected to the surgical conveyor 40. A first groove (not marked in the figure) is provided at the bottom of the support frame 102, a fixed bracket 1021 is provided outside the first groove, the fixed bracket 1021 is fixedly connected to the support frame 102, and a first rotating shaft (not marked in the figure) of the first handle 3013 passes through the fixed bracket 1021 and is rotatably connected to the fixed bracket 1021; The first rotating shaft side wall is sleeved with a first gear 3014, which 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 conveyor 40 thereon to move synchronously.

[0023] Further, the third axial movement structure 302 includes a second slider 3021, a second fixing member 3022 and a second handle 3023, the second slider 3021 is arranged on the top of the first slider 3011, the second slider 3021 is slidably connected to the first slider 3011, the second fixing member 3022 is fixedly connected to the second slider 3021, and the second fixing member 3022 is used for the second shell 402 to pass through and is fixedly connected to the second shell 402; The second rotating shaft (not marked in the figure) of the second handle 3023 passes through the second slider 3021, and the second handle 3023 is rotatably connected to the second slider 3021. The second gear 3024 is sleeved on the side wall of the first rotating shaft, and the second gear 3024 is meshingly connected 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 shell 402 thereon to move synchronously.

[0024] Furthermore, racks 30111 are provided on the top and bottom surfaces of the first slider 3011, the first gear 3014 is meshedly connected with the rack 30111 at the bottom of the first slider 3011, and the second gear 3024 is meshedly connected with the rack 30111 at the top of the first slider 3011. When the first handle 3013 is rotated, the first slider 3011 can be moved axially through the meshing of the rack, thereby driving the third axial moving structure 302 thereon to move synchronously. When the second handle 3023 rotates, the second slider 3021 is moved axially through the meshing of the rack, and at this time, the first slider 3011 is stationary.

[0025] At the same time, the length of the first slider 3011 is smaller than the length of the support frame 102, and the length of the second slider 3021 is smaller than the length of the first slider 3011, so that the first slider 3011 can move a distance relative to the support frame 102, and the second slider 3021 can move a distance relative to the first slider 3011.

[0026] Further, Figure 4 A schematic diagram schematically shows a first axial movement structure according to an embodiment of the present invention, Figure 5 The internal structure diagram of the third fixing member according to one embodiment of the present invention is schematically shown. Figure 4 , 5 As shown: The first axial moving structure 201 includes a third sliding block 2011, a third fixing member 2012 and a third handle 2013; The third fixing member 2012 is fixedly connected to the top of the base 101, 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; A first sliding groove 20121 is provided on the side wall of the third fixing member 2012 . The third sliding block 2011 can extend into the third fixing member 2012 through the first sliding groove 20121 and is rotationally connected to the third rotating shaft 20131 . The third sliding block 2011 is slidably connected to the first sliding groove 20121 .

[0027] Specifically, the third slider 2011 is threadedly connected to the third shaft 20131. When the third handle 2013 controls the third shaft 20131 to rotate, the third slider 2011 is slidably connected to the first slide groove 20121, so that the third slider 2011 moves axially. When the third slider 2011 is controlled to move toward the direction approaching 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 direction approaching the support frame 102, its first end will be raised, thereby increasing the inclination angle of the support frame 102, thereby realizing the angle adjustment of the surgical conveyor 40.

[0028] Furthermore, if Figure 2 , 3 As shown, a first limiting hole (not shown) is provided on the side wall of the support frame 102, and 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; A second limiting hole (not shown) is provided on the side wall of the second slider 3021 , and 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 .

[0029] With such a configuration, when the first slider 3011 is moved into position, the first stopper 3015 can be used to lock the first slider 3011 and the support frame 102, thereby fixing the surgical conveyor 40, thereby preventing the surgical conveyor 40 from sliding due to its own weight or external factors and affecting the interventional surgery. Similarly, when the second slider 3021 is moved into position, the second slider 3021 is locked with the first slider 3011 by the second limiter 3025, thereby fixing the second shell 402 to prevent the second shell 402 from sliding due to its own weight or external factors and affecting the interventional surgery.

[0030] Furthermore, a second slide groove 20122 is provided on the side wall of the third fixing member 2012, and the second slide groove 20122 is parallel to the first slide groove 20121; A third limiting hole (not shown) is provided on the side wall of the third sliding block 2011. The third limiting member 2014 can pass through the second sliding groove 20122 and be inserted into the third limiting hole. The third limiting member 2014 is used to lock the movement of the third sliding block 2011 relative to the third fixing member 2012. The third limiting member 2014 is slidably connected to the second sliding groove 20122 .

[0031] 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 of the third slider 2011 and the third fixing member 2012. At the same time, when not locked, the end of the third limiting member 2014 can still be partially inserted into the third limiting hole for storage, thereby avoiding the problem of loss of the third limiting member 2014 after being disassembled alone.

[0032] Furthermore, if Figure 1 As shown, a penetrating second groove 501 is provided on the side wall of the support frame 102 and the second slider 3021, and a damping sheet 502 is provided in the second groove 501, and the damping sheet 502 abuts against the first slider 3011; A fourth limit member 503 is provided on the outer side of the damping plate 502, and the fourth limit member 503 abuts against the damping plate 502. The fourth limit member 503 is used to control the abutment force between the fourth limit member 503 and the damping plate 502 to control the friction force between the first slider 3011 and the support frame 102, and between the second slider 3021 and the first slider 3011.

[0033] In this way, the damping sheet 502 is provided to increase the friction force to realize the two movement modes of the surgical conveyor 40, namely, the coarse adjustment and the fine adjustment.

[0034] 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 movable structure 201 , thereby reducing the volume of the entire device for easy storage.

[0035] To sum up, through the scheme of the present invention, the first driving device 20 includes a first axial moving structure 201 and a sliding bracket 202, and the two ends of the sliding bracket 202 are connected to the support frame 102 and the first axial moving structure 201. 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 regulating the inclination angle of the support frame 102, and the second driving device 30 is arranged on the support frame 102, and the surgical conveyor 40 is placed on the support frame 102. The second driving device 30 can control the axial movement of the surgical conveyor 40 to realize multi-angle and multi-position control of the surgical conveyor 40.
