[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] As shown in Figures 1 and 2, this embodiment provides an auxiliary support device, including a base 1 and a support arm 3. The base 1 is connected to the operating bed 100, and the support arm 3 is arranged on the base 1 in a liftable manner, and the support arm 3 can rotate relative to the base 1. The support arm 3 includes at least two arm rods, which are rotatably connected and stacked end to end. The end of the support arm 3 away from the base 1 is detachably connected to the surgical instrument 200 by means of bolt connection or clamping. The lifting and lowering of the support arm 3 relative to the base 1 can adjust the height of the surgical instrument 200 relative to the operating bed 100. The arm rods are rotatably connected and stacked end to end, which increases the movement range of the surgical instrument 200 relative to the operating bed 100, is suitable for different types of operations and patients of different heights, and has high adjustment flexibility.

[0046] The base 1 is provided with a support sleeve 2, and a lifting drive member 21 is provided within the support sleeve 2. The driving end of the lifting drive member 21 is connected to the arm rod of the support arm 3 near one end of the base 1, and is used to drive the support arm 3 to rise or fall, thereby changing the height of the surgical instrument 200 relative to the operating table 100. As shown in Figure 1, a schematic diagram of the state when the lifting drive member 21 drives the support arm 3 to a lower position, and as shown in Figure 2, a schematic diagram of the state when the lifting drive member drives the support arm 3 to a higher position. The outer wall of the support sleeve 2 is provided with a lifting button 22, which is electrically connected to the lifting drive member 21 within the support sleeve 2. The lifting and lowering of the support arm 3 can be controlled by the lifting button 22. The lifting drive member 21 can be a linear drive member such as an electric push rod or a linear motor, and the lifting button 22 is electrically connected to the electric push rod or linear motor.

[0047] Specifically, as shown in FIG3 , the auxiliary support device further includes a rotation mechanism 4 , which includes a brake button 41 , a rotating shaft 42 , and an electromagnetic brake 43 . The arms and base 1 , as well as adjacent arms, are connected via the rotating shaft 42 . Each rotating shaft 42 is provided with an electromagnetic brake 43 . The brake button 41 is electrically connected to the electromagnetic brake 43 and is used to control the electromagnetic brake 43 to brake or release the rotating shaft 42 . The brake button 41 controls the electromagnetic brake 43 to brake the rotating shaft 42 . To adjust the position of the surgical instrument 200 , pressing the brake button 41 releases the brake on the rotating shaft 42 , allowing the arms to rotate relative to each other to adjust the position of the surgical instrument 200 . Once the position of the surgical instrument 200 is adjusted, pressing the brake button 41 again causes the electromagnetic brake 43 to brake the rotating shaft 42 . This prevents the arms from rotating, thereby ensuring the stability of the position of the surgical instrument 200 .

[0048] For example, the support arm 3 includes three arms, namely the first arm 31, the second arm 32 and the third arm 33. Correspondingly, there are also three rotating shafts 42 and electromagnetic brakes 43. The rotating shaft 42 includes the first rotating shaft, the second rotating shaft and the third rotating shaft. The electromagnetic brake 43 includes the first electromagnetic brake, the second electromagnetic brake and the third electromagnetic brake. The first rotating shaft is fixed to the driving end of the lifting drive member 21. One end of the first arm 31 and both ends of the second arm 32 are provided with connecting holes. The first rotating shaft is provided at the first rotating shaft. The first electromagnetic brake is located within the connection hole of the first arm 31, between the first rotating shaft and the connection hole of the first arm 31. The second rotating shaft is fixed to the other end of the first arm 31 and located within the connection hole at one end of the second arm 32. The second electromagnetic brake is located between the second rotating shaft and the connection hole at one end of the second arm 32. The third rotating shaft is fixed to one end of the third arm 33 and located within the connection hole at the other end of the second arm 32. The third electromagnetic brake is located between the third rotating shaft and the connection hole at the other end of the second arm 32. There can be three or one brake button 41. When there are three brake buttons 41, each brake button 41 is connected to a corresponding electromagnetic brake 43, and the three electromagnetic brakes 43 can independently brake their corresponding rotating shafts 42. When there is only one brake button 41, all three electromagnetic brakes 43 are connected to the same brake button 41, and the single brake button 41 simultaneously controls all three electromagnetic brakes 43 to brake their corresponding rotating shafts 42.

[0049] Specifically, the electromagnetic holding brake 43 includes a traction magnet and a brake shoe. The traction magnet is located on the inner wall of the connection hole, and the brake shoe is located on the rotating shaft 42. When the brake button 41 is pressed, the traction magnet is energized to engage the brake shoe, separating the brake shoe from the rotating shaft 42. The arm can rotate relative to the rotating shaft 42, thereby adjusting the rotation angle of the arm and, in turn, the position of the surgical instrument 200. When the brake button 41 is pressed again, the traction magnet is de-energized and the brake shoe is released. The brake shoe is tightly engaged with the rotating shaft 42, preventing the arm from rotating relative to the rotating shaft 42, thereby ensuring that the position of the surgical instrument 200 does not change, thereby ensuring the stability of the position of the surgical instrument 200.

[0050] Furthermore, the rotating shaft 42 is a damping rotating shaft, and the rotating connection of each arm is connected by a damping rotating shaft, which can ensure that the arm can be adjusted by a certain drag force only when there is a clear position adjustment requirement, avoiding the arm from rotating randomly and unexpectedly, and further ensuring the stability of the position adjustment of the surgical instrument 200.

[0051] As shown in FIG1 , the surgical instrument 200 can be rotated to the head end 102 of the operating bed 100 by rotating the first arm 31, the second arm 32, and the third arm 33. As shown in FIG4 , the surgical instrument 200 can also be rotated to the tail end 103 of the operating bed 100 by rotating the first arm 31, the second arm 32, and the third arm 33 to change the angle between the arm and the base 1, as well as the angle between the arms.

[0052] During surgery, different types of surgeries require different angles at which the surgical instrument 200 enters the human body. To meet these requirements, the auxiliary support device further includes a mounting mechanism 5. The mounting mechanism 5 is located at the end of the support arm 3 away from the base 1 and is used to mount the surgical instrument 200. The mounting mechanism 5 is rotatably connected to the support arm 3. The mounting mechanism 5 can drive the surgical instrument 200 to rotate 360 ​​degrees relative to the support arm 3, thereby meeting the different angles at which the surgical instrument 200 enters the human body.

[0053] As shown in Figures 5-8, the mounting mechanism 5 includes a rotating assembly and a mounting member 54. The rotating assembly is disposed at the end of the support arm 3 away from the base 1. The rotating assembly is connected to the mounting member 54 and can drive the mounting member 54 to rotate. The mounting member 54 is used to mount the surgical instrument 200. The rotating assembly drives the mounting member 54 to rotate, which in turn drives the surgical instrument 200 to rotate. The mounting member 54 can be a mounting plate or mounting flange, such as a mounting member 54, that is conveniently connected to the surgical instrument 200. The surgical instrument 200 is detachably connected to the mounting member 54 by bolts or a clamping connection.

[0054] Specifically, the rotating assembly includes a turbine 52 and a worm 53. A mounting member 54 is connected to the center of the turbine 52. The turbine 52 and the worm 53 mesh and transmit power. Rotation of the worm 53 drives the mounting member 54 through the turbine 52. The mounting member 54 is connected to the center of the turbine 52 via a connecting shaft. Rotation of the worm 53 drives the turbine 52, which in turn drives the mounting member 54. The mounting member 54 drives the surgical instrument 200, thereby adjusting the angle at which the surgical instrument 200 enters the human body.

[0055] Of course, in other embodiments, the rotating assembly may also include a gear and a rack, the rack and the gear are meshed for transmission, the mounting member 54 is connected to the center of the gear, moving the rack can drive the gear to rotate, the rotation of the gear can drive the mounting member 54 to rotate, and the rotation of the mounting member 54 can drive the surgical instrument 200 to rotate.

[0056] Furthermore, the mounting mechanism 5 includes a mounting housing 51, which is fixed to the end of the support arm 3 away from the base 1. A turbine 52 is disposed within the mounting housing 51. One end of a worm 53 engages with the turbine 52 for transmission, while the other end extends out of the mounting housing 51. The worm 53 is rotationally connected to the mounting housing 51. The rotating assembly is mounted within the mounting housing 51, which protects the rotating assembly from damage while ensuring aesthetics. The other end of the worm 53 extends out of the mounting housing 51, facilitating manual rotation of the worm 53, which in turn drives the turbine 52.

[0057] In order to facilitate the operation of medical personnel, a rotating handle 55 is provided at the protruding end of the worm 53. By rotating the handle 55, the worm 53 is rotated, and then the mounting member 54 is rotated by the rotating handle 55 to adjust the posture of the surgical instrument 200.

[0058] When in use, the auxiliary support device is fixed to the operating bed 100 to support the surgical instrument 200. The base 1 is provided with a fixing assembly 11, which is used to fix the auxiliary support device to the operating bed 100. Specifically, the fixing assembly 11 includes a first fixing member and a second fixing member. The first fixing member is connected to the side of the operating bed 100 and is adjustable in height on the base 1 to accommodate operating beds 100 of different heights. The second fixing member is connected to the surface of the operating bed 100, supporting the auxiliary support device through the surface of the operating bed 100. The fixing assembly 11 is detachably connected to the operating bed 100, and the height of the first fixing member on the base 1 can be adjusted according to the height of the operating bed 100, which provides greater versatility and meets the installation requirements of operating beds 100 of various heights. In addition, the operating bed 100 can be evacuated when not needed, freeing up more working space for different types of surgeries.

[0059] As shown in Figures 9-11 , the first type of fixing assembly 11 provided in this embodiment includes a mounting slot 111 and a support base 112 for supporting lightweight surgical instruments 200. The mounting slot 111 is located below the support base 112 and engages with a steel bar 101 on one side of the operating bed 100. The support base 112 is positioned on the operating bed 100 surface to support the auxiliary support device. The mounting slot 111 is adjustable in height relative to the base 1. The mounting slot 111 engages with the steel bar 101 on the side of the operating bed 100 near the base 1. Fastening screws 115 penetrate through the sidewall of the mounting slot 111 from one side of the mounting slot 111 to secure the mounting slot 111 to the steel bar 101, thus accommodating steel bars 101 of varying widths. The support base 112 abuts the operating bed 100 surface to bear the weight of the auxiliary support device. Lightweight surgical instruments 200 are mounted on a single side of the operating bed 100, occupying less area on the operating bed 100.

[0060] Specifically, the base 1 is also provided with a height adjustment stud 116, and a threaded hole is provided on the side of the mounting groove 111 away from the slot. Two limiting holes are arranged at intervals along the height direction of the base 1, and the threaded hole is arranged between the two limiting holes, and the threaded hole and the two limiting holes are arranged coaxially. The height adjustment stud 116 passes through one of the limiting holes, the threaded hole and the other limiting hole in turn and is connected to the limiting nut 117. The height adjustment stud 116 rotates with the two limiting holes. By rotating the height adjustment stud 116 through the limiting nut 117, the mounting groove 111 can be driven to move up and down in the height direction, thereby adjusting the mounting groove 111 to cooperate with the steel bars 101 on the operating bed 100 of different heights.

[0061] Of course, in other embodiments, a slide groove extending in the height direction can also be provided on the base 1, and a slider cooperating with the slide groove is provided on the side of the installation groove 111 away from the groove mouth. The slider slides in the slide groove to adjust the height of the installation groove 111 on the base 1. After the height is adjusted, the slider is fixed in the slide groove by screws and other fixing parts.

[0062] As shown in Figures 12 and 13 , the second fixing assembly 11 provided in this embodiment for supporting heavy surgical instruments 200 includes a mounting base 113 and a fixing slot 114. The mounting base 113 spans the surface of the operating bed 100, and its two sides engage with the steel bars 101 on either side of the operating bed 100. Mounting lugs 1132 are provided on the side of the mounting base 1 near the base 1. The mounting lugs 1132 engage with the fixing slot 114, and the fixing slot 114 is height-adjustable within the base 1. The mounting base 113 is configured as an inverted U-shaped structure. The inner sides of the two side walls of the U-shaped mounting base 113 are provided with slots 1131 that engage with the steel bars 101. The two steel bars 101 on either side of the operating bed 101 are respectively placed in the two slots 1131. The steel bars 101 are engaged with the slots 1131 or secured by first locking screws 118. Mounting lugs 1132 are provided on the outer side of the side wall of the U-shaped mounting base 1 near the base 1. Two mounting lugs 1132 and two fixing slots 114 are provided. The two mounting lugs 1132 are fixedly connected to the two fixing slots 114 in a one-to-one manner, or are locked and secured by second locking screws 119 after being connected. The two fixing slots 114 are also height-adjustable. The height adjustment method for the fixing slots 114 is the same as that for the mounting slots 111 described above and will not be repeated here. This arrangement ensures the stability of the heavy surgical instrument 200 supported on the operating table 100.

[0063] Furthermore, as shown in Figures 14 to 16, a transfer cooperation position 12 is provided at the bottom of the base 1. The transfer cooperation position 12 is L-shaped and is used to cooperate with the transfer trolley 300. The L-shaped transfer cooperation position 12 cooperates with the table top of the transfer trolley 300 and a side surface adjacent to the table top. A connector 301 is also provided on the table top of the transfer trolley 300, and the two sides of the base 1 are fixedly connected to the table top through the connector 301. In this embodiment, the connector 301 includes an L-shaped connecting plate and a screw. The long arm of the L-shaped connecting plate is fixedly connected to the table top, and the short arm is fixedly connected to the side wall of the base 1 by a screw. By installing and cooperating with the transfer trolley 300 and the base 1, the disassembly and assembly and transportation of the auxiliary support device and the operating bed 100 are facilitated, and the cooperation between the auxiliary support device and the operating bed 100 is made more flexible.

[0064] The auxiliary support device provided in this embodiment can be transported to the vicinity of an operating bed 100 via a transport trolley 300 and mounted on the operating bed 100. The surgical instrument 200 is then mounted on the mounting member 54. The height of the support arm 3 relative to the operating bed 100 can be adjusted using the lift button 22 on the support sleeve 2, thereby adjusting the height of the surgical instrument 200 relative to the operating bed 100. By pressing the brake button 41, the electromagnetic brake 43 releases the brake on the rotating shaft 42. The relative angles of the stacked arms can then be adjusted to adjust the position of the surgical instrument 200 to different locations on the operating bed 100, accommodating different surgical procedures and patients of varying heights. After the position of the surgical instrument 200 is adjusted, pressing the brake button 41 again causes the electromagnetic brake 43 to brake the rotating shaft 42, preventing further positional changes in the arms. This ensures the stability of the position of the surgical instrument 200 and ensures a smooth surgical procedure. To accommodate the different angles at which the surgical instrument 200 enters the human body, a mounting mechanism 5 is provided at the end of the support arm 3 away from the base 1. A mounting member 54 for the surgical instrument 200 is secured to the center of a turbine 52. The turbine 52 cooperates with a worm 53. By rotating a handle 55, the worm 53 rotates, driving the turbine 52. This rotation of the turbine 52 drives the mounting member 54, which in turn drives the surgical instrument 200, thereby adjusting the angle at which the surgical instrument 200 enters the human body. For lightweight surgical instruments 200, a fixing assembly 11 fixed to one side of the operating bed 100 is provided to connect to the auxiliary support device, reducing the area occupied by the operating bed 100. For heavy surgical instruments 200, mounting seats 113 fixed to both sides of the operating bed 100 cooperate with fixing slots 114 on the base 1 to ensure the stability of the support for heavy surgical instruments 200. Furthermore, the provision of a transfer trolley 300 in conjunction with the base 1 facilitates the assembly and disassembly of the auxiliary support device, providing greater flexibility.
