[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 11As shown, the present invention proposes a double rocker perspective spinal surgery stand, including an adjustment mechanism 1, a rocker mechanism 2, and a support mechanism 3. The adjustment mechanism 1 includes a screw mechanism 11, and the screw mechanism 11 includes a first screw 113 and a connecting rod 115. Both ends of the first screw 113 are provided with a first connecting portion 114, and both ends of the first screw 113 are provided with a shell 14. A connecting block 1111 is provided in the shell 14, and the connecting block 1111 is slidably connected to the shell 14. The top of the connecting block 1111 passes through the top of the shell 14 and is arranged outside the shell 14. The connecting block 1111 is sleeved on the first screw 11 3, the connecting block 1111 is rotatably connected with the first screw rod 113, a movable block 1112 is installed at the bottom of the connecting block 1111, a second screw rod 1110 is sleeved in the movable block 1112, the second screw rod 1110 is threadedly connected with the movable block 1112, first supports 1113 are installed at both ends of the second screw rod 1110, a second bevel gear 119 is installed at one end of the second screw rod 1110, the connecting rod 115 is provided with a first bevel gear 118 meshing with the second bevel gear 119, and second connecting parts 116 with the same specifications as the first connecting part 114 are provided at both ends of the connecting rod 115;

[0037] The outer sleeve of the first screw rod 113 is provided with at least two sliders 111, and the sliders 111 are slidably connected with the first screw rod 113. The slider 111 is provided with a button mechanism 112, and the button mechanism 112 includes a cylinder 1121, and the cylinder 1121 is provided with a first through groove 1122 for accommodating the first screw rod 113. The length of the first through groove 1122 is longer than the diameter of the first screw rod 113. A clamping block 1123 is installed at one end of the cylinder 1121, and a thread matching the thread of the first screw rod 113 is provided on one side of the clamping block 1123. An elastic member 1124 is provided on one side of the clamping block 1123.

[0038] The rocker mechanism 2 includes a matching portion 24 matching the first connecting portion 114, and the matching portion 24 is engaged with the first connecting portion 114;

[0039] The supporting mechanism 3 is arranged above the adjusting mechanism 1 .

[0040] The curvature and width of the spinal surgery frame can be adjusted by rotating the connecting rod 115. Specifically, when the curvature of the surgery frame needs to be adjusted, the connecting rod 115 is rotated through the rocker mechanism 2, and the connecting rod 115 drives the first bevel gear 118 to rotate, and the first bevel gear 118 is meshed with the second bevel gear 119, so that the second bevel gear 119 rotates accordingly, and the rotation of the second bevel gear 119 drives the second screw rod 1110 to rotate, and further the rotation of the second screw rod 1110 causes the movable block 1112 to move along the second screw rod 1110, and the movement of the movable block 1112 changes the position of the connecting block 1111, thereby changing the curvature of the support mechanism 3. The connecting rod 115 can make the second screw rods 1110 on both sides rotate synchronously.

[0041] When the width of the spinal surgery frame needs to be adjusted, the first screw rod 113 is rotated through the rocker mechanism 2, and the rotation of the first screw rod 113 causes the slider 111 to move along the first screw rod 113. Specifically, the first screw rod 113 drives the block 1123 to move through the thread, and the block 1123 drives the slider 111 to move through the cylinder 1121. The slider 111 moves outward, and the width of the surgery frame increases, and the slider 111 moves inward, and the width of the surgery frame decreases.

[0042] When it is necessary to quickly adjust the width of the spinal surgery frame, press and hold the cylinder 1121 of the button mechanism 112 to move the cylinder 1121 into the slider 111. When the cylinder 1121 moves into the slider 111, the block 1123 is separated from the thread of the first screw rod 113, and the locked state of the slider 111 is released. At this time, the slider 111 can slide freely on the first screw rod 113, and the operator can manually move the slider 111 to the desired position. When the slider 111 reaches the desired position, release the cylinder 1121 of the button mechanism 112. After releasing the cylinder 1121, the elastic member 1124 pushes the block 1123 to return to its original position, and the thread of the block 1123 is engaged with the thread of the first screw rod 113 again to lock the position of the slider 111. The operation is simple and convenient.

[0043] Optionally, in some embodiments, a motor is installed at one end of the first screw rod 113, and a motor is installed at one end of the connecting rod 115. The motor can accurately control the rotation angle and speed through the controller, thereby achieving high-precision adjustment of the width and curvature of the opening knife holder. The motor drive can respond quickly to control instructions and achieve rapid adjustment. Automated adjustment can significantly shorten the adjustment time and improve surgical efficiency.

[0044] Further, as a preferred embodiment of the present invention but not limited thereto, the adjustment mechanism 1 includes an articulated seat 13, the articulated seat 13 is articulated with at least one articulated block 33, the articulated block 33 is installed with a first connecting plate 34, a support plate 32 is arranged between the first connecting plate 34 and the articulated block 33, a second connecting plate 35 is installed on the top of the slider 111, one end of the support plate 32 is arranged between the slider 111 and the second connecting plate 35, a support pad 31 is arranged above the support plate 32, one end of the support pad 31 is fixedly connected to the first connecting plate 34, and the other end of the support pad 31 is fixedly connected to the second connecting plate 35. The design of the articulated seat 13 and the articulated block 33 makes the curvature adjustment of the open tool holder more flexible. The support plate 32 connects the slider 111 and the articulated block 33, provides structural rigid support, and ensures the stability of the open tool holder during the adjustment process. The support pad 31 provides additional support and buffering, reduces vibration and shaking during the adjustment process, and improves the overall stability.

[0045] Further, as a preferred embodiment of the present invention but not a limitation, the elastic member 1124 is a spring, and the side view projection of the support plate 32 is an upwardly convex arc. The spring is used as the elastic member 1124 to provide elastic force to ensure that the block 1123 is engaged with the thread of the first screw rod 113 when no external force is applied, thereby locking the position of the slider 111. The spring is installed between the block 1123 and the cylinder 1121. When the cylinder 1121 is pressed, the spring is compressed, and the block 1123 is separated from the thread of the first screw rod 113, thereby releasing the locked state of the slider 111. After the cylinder 1121 is released, the spring returns to its original state, pushing the block 1123 to engage with the thread of the first screw rod 113 again, thereby locking the position of the slider 111. The upwardly convex arc design of the support plate 32 can better adapt to the physiological curvature of the spine and provide better support and stability.

[0046] Optionally, in some embodiments, the block 1123 is sleeved in the barrel 1121, and the barrel 1121 is threadedly connected to the block 1123. The split design of the block 1123 and the barrel 1121 allows the two components to be independently disassembled and replaced, which is convenient for maintenance and repair.

[0047] Further, as a preferred embodiment of the present invention but not limiting, the top of the housing 14 is provided with a second through slot 16 for accommodating the top of the connecting block 1111, and the connecting block 1111 is slidably connected to the second through slot 16. The housing 14 is used to protect and support the internal mechanical components. The second through slot 16 is slidably connected to the top of the connecting block 1111 to ensure that the connecting block 1111 can move smoothly during the adjustment process, reduce friction and jamming, and the second through slot 16 provides a sliding guide to ensure that the connecting block 1111 does not deviate from the track during the movement, thereby improving the stability of the overall structure.

[0048] Further, as a preferred embodiment of the present invention but not limited thereto, the rocker mechanism 2 includes a rocker arm 21, a handle 22 is installed at one end of the rocker arm 21, a latch 23 is installed at the other end of the rocker arm 21, and the matching portion 24 is arranged at one end of the latch 23. The matching portion 24 is a slot, and the first connecting portion 114 and the second connecting portion 116 are blocks, which are engaged with the slot. The operator can drive the rocker arm 21 to rotate through the handle 22, and the rocker arm 21 transmits force to the matching portion 24 of the latch 23, and the first screw rod 113 or the connecting rod 115 can be driven to rotate through the connecting portion. Since the matching portion 24 is engaged with the connecting portion, the rocker arm 21 can be quickly separated from the screw mechanism 11 when not in use. The engaging design of the block and the slot ensures the stable connection between the rocker mechanism 2 and the adjustment mechanism 1, and the engaging connection ensures the effective transmission of the rotational force, thereby improving the accuracy and stability of the adjustment.

[0049] Optionally, in some embodiments, the matching portion 24 is a card block, and the first connecting portion 114 and the second connecting portion 116 are card slots.

[0050] Further, as a preferred embodiment of the present invention but not limiting, the top surface of the slider 111 is provided with a first groove 1114 for accommodating the support plate 32, and the top surface of the hinge block 33 is provided with a second groove 331 for accommodating the support plate 32. The design of the first groove 1114 and the second groove 331 enables the support plate 32 to be stably fixed on the slider 111 and the hinge block 33. The side walls of the first groove 1114 and the second groove 331 can provide support for the support plate 32.

[0051] Further, as a preferred embodiment of the present invention but not limited thereto, both sides of the housing 14 are provided with through holes 15 for the connecting rod 115 to pass through, and both ends of the connecting rod 115 are provided with sleeves 117, the sleeves 117 are arranged in the through holes 15, the sleeves 117 are rotatably connected to the through holes 15, and the first connecting portion 114 is arranged in the sleeves 117. The sleeves 117 can ensure that the first screw rod 113 can rotate smoothly during rotation, reducing friction and wear. The sleeves 117 can provide protection for the first connecting portion 114, prevent external dust and contaminants from entering, and keep the first connecting portion 114 clean. The design of the sleeves 117 can provide physical protection for the first connecting portion 114, prevent external impact and damage during installation and use, and the sleeves 117 can provide positioning for the insertion of the plug 23, ensuring that the plug 23 can be accurately inserted into the first connecting portion 114, simplifying the installation process.

[0052] Further, as a preferred embodiment of the present invention but not limiting, the top surface height of the slider 111 is higher than the top surface height of the hinge block 33. One end of the support plate 32 is higher than the other end, so that the surgeon can lie prone, which is ergonomic.

[0056] The outer sleeve of the first screw rod 113 is provided with at least two sliders 111, and the sliders 111 are slidably connected with the first screw rod 113. The slider 111 is provided with a button mechanism 112, and the button mechanism 112 includes a cylinder 1121, and the cylinder 1121 is provided with a first through groove 1122 for accommodating the first screw rod 113. The length of the first through groove 1122 is longer than the diameter of the first screw rod 113. A clamping block 1123 is installed at one end of the cylinder 1121, and a thread matching the thread of the first screw rod 113 is provided on one side of the clamping block 1123. An elastic member 1124 is provided on one side of the clamping block 1123.

[0057] The rocker mechanism 2 includes a matching portion 24 matching the first connecting portion 114, and the matching portion 24 is engaged with the first connecting portion 114;

[0058] The supporting mechanism 3 is arranged above the adjusting mechanism 1 .

[0059] The curvature and width of the spinal surgery frame can be adjusted by rotating the connecting rod 115. Specifically, when the curvature of the surgery frame needs to be adjusted, the connecting rod 115 is rotated through the rocker mechanism 2, and the connecting rod 115 drives the first bevel gear 118 to rotate, and the first bevel gear 118 is meshed with the second bevel gear 119, so that the second bevel gear 119 rotates accordingly, and the rotation of the second bevel gear 119 drives the second screw rod 1110 to rotate, and further the rotation of the second screw rod 1110 causes the movable block 1112 to move along the second screw rod 1110, and the movement of the movable block 1112 changes the position of the connecting block 1111, thereby changing the curvature of the support mechanism 3. The connecting rod 115 can make the second screw rods 1110 on both sides rotate synchronously.

[0060] When the width of the spinal surgery frame needs to be adjusted, the first screw rod 113 is rotated through the rocker mechanism 2, and the rotation of the first screw rod 113 causes the slider 111 to move along the first screw rod 113. Specifically, the first screw rod 113 drives the block 1123 to move through the thread, and the block 1123 drives the slider 111 to move through the cylinder 1121. The slider 111 moves outward, and the width of the surgery frame increases, and the slider 111 moves inward, and the width of the surgery frame decreases.

[0061] When it is necessary to quickly adjust the width of the spinal surgery frame, press and hold the cylinder 1121 of the button mechanism 112 to move the cylinder 1121 into the slider 111. When the cylinder 1121 moves into the slider 111, the block 1123 is separated from the thread of the first screw rod 113, and the locked state of the slider 111 is released. At this time, the slider 111 can slide freely on the first screw rod 113, and the operator can manually move the slider 111 to the desired position. When the slider 111 reaches the desired position, release the cylinder 1121 of the button mechanism 112. After releasing the cylinder 1121, the elastic member 1124 pushes the block 1123 to return to its original position, and the thread of the block 1123 is engaged with the thread of the first screw rod 113 again to lock the position of the slider 111. The operation is simple and convenient.

[0062] The adjustment mechanism 1 includes an articulated seat 13, the articulated seat 13 is articulated with at least one articulated block 33, the articulated block 33 is installed with a first connecting plate 34, a support plate 32 is arranged between the first connecting plate 34 and the articulated block 33, a second connecting plate 35 is installed on the top of the slider 111, one end of the support plate 32 is arranged between the slider 111 and the second connecting plate 35, a support pad 31 is arranged above the support plate 32, one end of the support pad 31 is fixedly connected to the first connecting plate 34, and the other end of the support pad 31 is fixedly connected to the second connecting plate 35. The design of the articulated seat 13 and the articulated block 33 makes the curvature adjustment of the knife holder more flexible. The support plate 32 connects the slider 111 and the articulated block 33, provides structural rigid support, and ensures the stability of the knife holder during the adjustment process. The support pad 31 provides additional support and buffering, reduces vibration and shaking during the adjustment process, and improves the overall stability.

[0063] The elastic member 1124 is a spring, and the side view projection of the support plate 32 is an upward convex arc. The spring is used as the elastic member 1124 to provide elastic force to ensure that the block 1123 is engaged with the thread of the first screw rod 113 when no external force is applied, thereby locking the position of the slider 111. The spring is installed between the block 1123 and the cylinder 1121. When the cylinder 1121 is pressed, the spring is compressed, and the block 1123 is separated from the thread of the first screw rod 113, thereby releasing the locked state of the slider 111. After the cylinder 1121 is released, the spring returns to its original state, pushing the block 1123 to engage with the thread of the first screw rod 113 again, thereby locking the position of the slider 111. The upward convex arc design of the support plate 32 can better adapt to the physiological curvature of the spine and provide better support and stability.

[0064] The top of the housing 14 is provided with a second through slot 16 for accommodating the top of the connecting block 1111, and the connecting block 1111 is slidably connected to the second through slot 16. The housing 14 is used to protect and support the internal mechanical components. The second through slot 16 is slidably connected to the top of the connecting block 1111 to ensure that the connecting block 1111 can move smoothly during the adjustment process, reduce friction and jamming, and the second through slot 16 provides a sliding guide to ensure that the connecting block 1111 does not deviate from the track during the movement, thereby improving the stability of the overall structure.

The operator can drive the rocker arm 21 to rotate through the handle 22, and the rocker arm 21 transmits force to the matching portion 24 of the latch 23, and the first screw rod 113 or the connecting rod 115 can be driven to rotate through the connecting portion. Since the matching portion 24 is engaged with the connecting portion, the rocker arm 21 can be quickly separated from the screw mechanism 11 when not in use. The engaging design of the block and the slot ensures the stable connection between the rocker mechanism 2 and the adjustment mechanism 1, and the engaging connection ensures the effective transmission of the rotational force, thereby improving the accuracy and stability of the adjustment.

[0066] Both sides of the housing 14 are provided with through holes 15 for the connecting rod 115 to pass through, and both ends of the connecting rod 115 are provided with sleeves 117, which are arranged in the through holes 15, and the sleeves 117 are rotatably connected with the through holes 15, and the first connecting part 114 is arranged in the sleeves 117. The sleeves 117 can ensure that the first screw rod 113 can rotate smoothly when rotating, reducing friction and wear. The sleeves 117 can provide protection for the first connecting part 114, prevent external dust and pollutants from entering, and keep the first connecting part 114 clean. The design of the sleeves 117 can provide physical protection for the first connecting part 114, and prevent external impact and damage during installation and use. The sleeves 117 can provide positioning for the insertion of the plug 23, ensuring that the plug 23 can be accurately inserted into the first connecting part 114, simplifying the installation process.

[0067] The top surface height of the sliding block 111 is higher than the top surface height of the hinge block 33. One end of the support plate 32 is higher than the other end, so that it is convenient for the surgeon to lie prone, which is ergonomic.

[0068] The articulated seat 13 includes a rod body 131, support blocks 133 are installed at both ends of the rod body 131, an arc groove 134 is provided on one side of the support block 133, and a second support 132 is provided on the outer cover of the rod body 131, and the second support 132 is rotatably connected to the rod body 131. The rod body 131 is used to connect and support other components, and the support block 133 is used to provide stable support for the rod body 131. The arc groove 134 is used to accommodate the articulated block 33, thereby increasing the width adjustment range of the spinal surgery frame, and the arc groove 134 can also limit the articulated block 33 to prevent the articulated block 33 from slipping out of the rod body 131.

[0069] The implementation method of the second embodiment is as follows:

[0070] The difference between the second embodiment and the first embodiment is that a motor is installed at one end of the first screw rod 113, and a motor is installed at one end of the connecting rod 115. The motor can accurately control the rotation angle and speed through the controller, thereby achieving high-precision adjustment of the width and arc of the opening knife holder. The motor drive can respond quickly to the control command and achieve rapid adjustment. Automated adjustment can significantly shorten the adjustment time and improve surgical efficiency.

[0071] The implementation method of the third embodiment is as follows:

[0072] The difference between the third embodiment and the first embodiment is that the clamping block 1123 is sleeved in the cylinder 1121, and the cylinder 1121 is threadedly connected to the clamping block 1123. The split design of the clamping block 1123 and the cylinder 1121 allows the two components to be independently disassembled and replaced, which is convenient for maintenance and repair.

[0073] The implementation method of the fourth embodiment is as follows:

[0074] The difference between the fourth embodiment and the first embodiment is that the top surface of the slider 111 is provided with a first groove 1114 for accommodating the support plate 32, and the top surface of the hinge block 33 is provided with a second groove 331 for accommodating the support plate 32. The design of the first groove 1114 and the second groove 331 enables the support plate 32 to be stably fixed on the slider 111 and the hinge block 33. The side walls of the first groove 1114 and the second groove 331 can provide support for the support plate 32.

[0075] Specifically, the working principle of the present invention is as follows:

[0076] When the curvature of the spinal surgery frame needs to be adjusted, the connecting rod 115 is rotated through the rocker mechanism 2. The connecting rod 115 drives the first bevel gear 118 to rotate, and the first bevel gear 118 meshes with the second bevel gear 119, so that the second bevel gear 119 rotates accordingly. The rotation of the second bevel gear 119 drives the second screw rod 1110 to rotate, and further moves the movable block 1112 along the second screw rod 1110, thereby changing the position of the connecting block 1111, and finally adjusting the curvature of the support mechanism 3. The design of the connecting rod 115 ensures that the second screw rods 1110 on both sides rotate synchronously, ensuring the uniformity of the curvature adjustment.

[0077] When the width of the spinal surgery rack needs to be adjusted, the first screw rod 113 is rotated through the rocker mechanism 2. The rotation of the first screw rod 113 drives the slider 111 to move along the first screw rod 113 through the thread. Specifically, the first screw rod 113 drives the block 1123 to move through the thread, and the block 1123 drives the slider 111 to move through the cylinder 1121. When the slider 111 moves outward, the width of the surgery rack increases; when the slider 111 moves inward, the width of the surgery rack decreases. This design ensures the accuracy and stability of width adjustment.

[0078] When the width of the spinal surgery frame needs to be adjusted quickly, the operator can press and hold the cylinder 1121 of the button mechanism 112 to move the cylinder 1121 into the slider 111. At this time, the block 1123 is separated from the thread of the first screw rod 113, the locking state of the slider 111 is released, and the slider 111 can slide freely on the first screw rod 113. The operator can manually move the slider 111 to the desired position. When the slider 111 reaches the desired position, the cylinder 1121 of the button mechanism 112 is released, and the elastic member 1124 (such as a spring) pushes the block 1123 to return to its original position, and the thread of the block 1123 is engaged with the thread of the first screw rod 113 again to lock the position of the slider 111. This quick adjustment mechanism greatly improves the convenience and efficiency of operation.

[0079] In summary, the present invention solves the problem that the traditional spinal surgery frame adjustment mechanism has a complex structure and cannot quickly adjust the width.
