Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a steel plate pre-bending device for clinical orthopedic surgery. Background Art

[0002] The steel plate pre-bending device for orthopedic clinical surgery refers to a device used to bend medical steel plates into specific shapes to better fit the patient's bone shape during orthopedic surgery. The main technical issue addressed by this device is the precise bending of medical steel plates. Commonly used methods include setting up specific structures, such as laser scanners and laser depth finders in bending simulation devices, to collect information on the patient's treatment area and obtain relevant data; utilizing a pressure arm mechanism and a bending mechanism to work together, with the pressure arm mechanism, such as the first electric robotic arm, driving the bending roller to adjust its position, and the bending mechanism, such as the second electric robotic arm, driving the fixing device to bend the steel plate. During the bending process, the steel plate uses the bending roller as the force point to complete the bending operation.

[0003] Chinese patent publication number CN216501682U discloses a pre-bending device for orthopedic clinical surgical plates. The device comprises a workbench and a pre-bending assembly mounted on the workbench. The pre-bending assembly comprises a fixed plate, a compression plate, and a bending plate. The fixed plate and the compression plate are mounted parallel to the workbench, forming a compression groove for accommodating the surgical plate. The bending plate is rotatably connected to the fixed plate. This device facilitates pre-bending of orthopedic clinical surgical plates, is simple to operate, saves time and effort, and has high applicability.

[0004] However, in actual use, existing technologies have shortcomings in steel plate bending and processing. Some devices rely on manual labor for bending operations, making it difficult to precisely control the bending force. The accuracy cannot meet the high-precision requirements of orthopedic surgery, which can easily lead to poor fit between the steel plate and the bone, affecting the surgical outcome. Furthermore, the devices are not intelligent enough to collect data and simulate bending based on individual patient differences, making it difficult to plan an adaptation plan. During steel plate processing, existing technologies often ignore heating assistance, applying direct bending force, which increases the difficulty of pre-bending and may also damage the steel plate. After bending, there is a lack of efficient cooling, shaping, cleaning, and disinfection methods. Slow and uneven cooling affects shaping, and incomplete cleaning and disinfection increases the risk of surgical infection. Summary of the Invention

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1, as Figure 1 and Figure 2 As shown, a steel plate pre-bending device for orthopedic clinical surgery includes a box body 1, a controller 3 is fixedly installed on the upper end of the box body 1, a box cover 2 is rotatably connected to the upper end of the box body 1 through a hinge, a bending drive structure 4 is provided on the inner surface of the box body 1, a clamping structure 5 is provided on the upper end of the bending drive structure 4, and a bending auxiliary structure 6 is symmetrically provided on the front and back of the upper end of the bending drive structure 4.

[0034] Furthermore, in order to clean the steel plate and change the properties of the steel plate through heat exchange, thereby improving the quality of pre-bending and shaping, refer to Figure 3A clean water tank 13 is provided at the lower part of the inner cavity of the box body 1, and a water pump 15 is fixedly connected to the bottom wall of the inner surface of the clean water tank 13. A sewage tank 14 is provided in the middle part of the inner surface of the box body 1, and a processing chamber 17 is provided at the upper end of the box body 1. The output end of the water pump 15 is fixedly connected to a water pipe 16 communicating with the processing chamber 17, and a solenoid valve communicating with the sewage tank 14 is provided on the bottom wall of the inner cavity of the processing chamber 17. The temperature control box 11 and the air pump 12 connected to the bending auxiliary structure 6 are fixedly installed in the part of the inner cavity of the box body 1 located at the lower part of the box cover 2, and a cooling circulation pump and a heater are installed in the temperature control box 11.

[0035] Air is delivered to the bending auxiliary structure 6 by the air pump 12, and then delivered into the cleaning liquid in the processing chamber 17 through the bending auxiliary structure 6, forming bubbles. Then, through the interaction between the temperature control box 11 and the bending auxiliary structure 6, the cleaning liquid in the processing chamber 17 is heated up. The temperature increase drives the activity of the molecular structure of the steel plate to increase, making it easier to plastically deform under the action of external force, thereby achieving precise bending;

[0036] Heating intensifies the movement of water molecules in the cleaning solution, allowing the steel plate to be evenly heated during immersion, eliminating the risk of cracks caused by local stress concentration during the bending process. Combined with the stirring effect brought by the tumbling of air bubbles, the temperature field of each part of the steel plate is more uniform, and the bending angle and curvature are more precisely controlled, ensuring that the orthopedic steel plate meets the mechanical properties and morphological requirements of clinical implantation after bending.

[0037] It should be noted that the temperature control box 11 is a conventional heat exchange device, which is filled with coolant and circulated by a circulating pump. Furthermore, a heater is provided for heating using the principle of electric heating. This structure has been widely used in the prior art. In the present invention, only the heating and cooling functions are realized by it, and its internal structure, operating principle, wiring, and control method are not shown or described in detail.

[0038] Furthermore, the air pump 12 is a conventional pump body for drawing external air and sending it out through the output port. It is also a conventional device in the prior art. Its operating principle is similar to that of a fish tank oxygen pump. This structure has been widely used in the prior art. In the present invention, its internal structure, operating principle, wiring, and control method will no longer be displayed or elaborated.

[0039] Further, in order to realize the pre-bending of steel plates, see Figure 3 The bending drive structure 4 includes a mounting plate 41 located in the inner cavity of the processing chamber 17. Cables 45 are fixedly connected to the left and right ends of the mounting plate 41 symmetrically in front and back. The ends of the two cables 45 on the same side away from the mounting plate 41 pass through the inner surface of the processing chamber 17 and extend to the inner cavity of the box 1 and are wound around a winding roller 2 44 that is rotatably connected to the inner cavity of the box 1. The two winding rollers 2 44 are connected by a synchronous belt drive, and a motor 2 46 connected to its transmission is provided at the front end of one of the winding rollers 2 44.

[0040] The winding roller 2 44 is driven to rotate by the action of the motor 2 46, and then the winding roller 2 44 acts on the cable 45 to tighten it, and the cable 45 pulls the mounting plate 41 to drive the mounting plate 41 to rise or fall in the processing chamber 17, so that the steel plate can be immersed in the cleaning liquid in the processing chamber 17 or the bent steel plate can be lifted from the cleaning in the processing chamber 17.

[0041] Furthermore, in order to fix the steel plates that need to be pre-bent, refer to Figure 4 and 5 The clamping structure 5 includes a central axis 54 fixedly connected to the upper end of the mounting plate 41, and the outer surface of the central axis 54 is symmetrically connected to the telescopic rod 53 for rotation. The ends of the two telescopic rods 53 away from the central axis 54 are both rotatably connected to the base 51 that is slidably connected to the arc groove 42 on the same side, and the upper ends of the two bases 51 are both provided with a clamping assembly 52.

[0042] During operation of this embodiment, the steel plate is clamped by the clamping structure 5 provided on the upper portion of the mounting plate 41. The driving assembly 43 drives the clamping structure 5 in conjunction with the arc groove 42 limiting the position of the base 51 to achieve bending of the steel plate to a predetermined angle. In conjunction with the heating of the processing chamber 17 by the bending auxiliary structure 6, the steel plate is forced to bend to a predetermined angle following the gradual movement of the base 51 and the clamping assembly 52.

[0043] After bending to a predetermined angle and continuously heating for a period of time, the cleaning liquid in the processing chamber 17 is cooled by the action of the bending auxiliary structure 6. When the coolant circulates and cools down, the movement of bubbles in the liquid can accelerate the contact and replacement between the low-temperature coolant and the surface of the steel plate, quickly taking away the heat of the steel plate. Compared with static cooling, the agitation of the bubbles causes the surface temperature of the steel plate to drop to the target value faster, shortening the cooling time and improving the efficiency of the steel plate shaping after pre-bending;

[0044] Furthermore, low-temperature treatment can keep the steel plate at the preset curvature while restoring the mechanical properties of the material, ensuring the stability of the pre-bent shape.

[0045] Embodiment 2. Based on embodiment 1, this embodiment limits the running path of the base 51 and drives it to move along a predetermined route through the cooperation between the arc groove 42 on the mounting plate 41 and the driving assembly 43; the motor 431 in the driving assembly 43 drives the winding roller 432 to rotate, and drives the slider 437 to slide in the slide groove 434 through the annular rope 433, thereby driving the connecting ring 436 and the pulley 511 to move; the gear 512 on the pulley 511 engages with the tooth groove in the arc groove 42 to rotate the base 51 and cooperate with the telescopic rod 53 to produce an arc trajectory; the dual-axis motor 525 in the clamping assembly 52 drives the screw 524, driving the sliding plate 521 to make the Ω-shaped pad 522 clamp the steel plate, and the rubber material and honeycomb structure prevent the steel plate from sliding and being damaged.

[0046] Specifically, in order to drive and guide the base 51 and the clamping assembly 52 to move along a predetermined trajectory to pre-bend the steel plate, refer to Figure 4 and Figure 5 The upper end of the mounting plate 41 is symmetrically provided with arc grooves 42 that are slidably connected to the clamping structure 5. The outer arc surfaces of the two arc grooves 42 are provided with tooth grooves, and the inner arc surfaces of the two arc grooves 42 are provided with driving components 43 that drive the clamping structure 5.

[0047] The arc groove 42 is used to limit the running path of the base 51. The base 51 can be driven to move along a predetermined route through the cooperation of the driving component 43 and the arc groove 42. Due to the slight differences in the angles of the human skeleton, when the steel plate is used, it needs to be adjusted from four dimensions, that is, through bending in the same direction, bending in different directions or bending on one side, so that the driving components 43 on both sides can drive the base 51 on the same side respectively, thereby adapting to different bending requirements.

[0048] Further, in order to realize the driving of the base 51 and the clamping assembly 52, refer to Figure 6 and Figure 7 The driving component 43 includes a slide groove 434 provided on the inner arc surface of the arc groove 42, and a limit groove 435 is symmetrically provided on the inner surface of the slide groove 434. The inner surfaces of the slide groove 434 and the limit groove 435 are slidably connected with a slider 437. The side of the slider 437 close to the arc groove 42 is fixedly connected to a connecting ring 436 rotatably connected to the clamping structure 5. The end of the slider 437 away from the connecting ring 436 is fixedly connected to an annular rope 433. Both ends of the annular rope 433 away from the slider 437 extend to the inner cavity of the mounting plate 41 and are wound around a winding roller 432. The two ends of the annular rope 433 are opposite to the winding direction of the winding roller 432. The front end of the winding roller 432 is provided with a motor 431 connected to it for transmission.

[0049] The motor 431 drives the winding roller 432 to rotate. Since the winding directions of the circular rope 433 on the winding roller 432 are opposite, during the rotation of the winding roller 432, one side is wound up and the other side is released. Then, during the specific operation, the circular rope 433 is driven to slide in the slide groove 434. At this time, the slider 437 fixed to the outer surface of the circular rope 433 will slide in the slide groove 434 and the limit groove 435, thereby driving the connecting ring 436 and the pulley 511 it is connected to to move along the movement of the circular rope 433. Since the trajectory of the slide groove 434 is the same as the trajectory of the arc groove 42, the base 51 will move along the trajectory of the arc groove 42 under the action of the connecting ring 436, and then the steel plate is fixed by the upper clamping assembly 52 to drive the steel plate to move synchronously.

[0050] Further, in order to realize the bending of the steel plate along the predetermined trajectory, refer to Figure 8 The upper end of the base 51 is symmetrically provided with a sliding groove 514 that is slidably connected to the clamping assembly 52. ​​A connecting groove 513 that is rotatably connected to the telescopic rod 53 is opened on the side of the base 51 close to the telescopic rod 53. The lower end of the base 51 is fixedly connected to a pulley 511 that is slidably connected to the inner surface of the arc-shaped groove 42. The outer surface of the pulley 511 is rotatably connected to the inner surface of the connecting ring 436. The outer surface of the pulley 511 is fixedly connected to a gear 512 that meshes with the inner tooth groove of the adjacent arc-shaped groove 42.

[0051] The pulley 511 is driven to move along the trajectory of the arc groove 42 through the action of the connecting ring 436. Synchronously, since the outer surface of the pulley 511 is equipped with a gear 512 that meshes with the tooth groove on the inner wall of the arc groove 42, during the movement of the pulley 511, the base 51 will be driven to rotate by the meshing action, and under the relative cooperation of the telescopic rod 53 and the driving assembly 43, an arc trajectory is generated, thereby achieving the effect of uniform force bending of the steel plate.

[0052] Further, to achieve the clamping and fixing of the steel plate, refer to Figure 8 The clamping assembly 52 includes sliding plates 521 symmetrically distributed front and back and slidingly connected to the second slide groove 514, and a center plate 523 fixedly installed on the upper end of the base 51. The two sliding plates 521 are arranged in an array and fixedly connected at one end close to each other with a number of Ω-shaped pads 522. The outer surfaces of the several Ω-shaped pads 522 are all made of rubber and the interior is honeycomb-shaped. A dual-axis motor 525 is fixedly connected to the inner cavity of the base 51. The output shafts on both sides of the dual-axis motor 525 are fixedly connected to the screws 524 rotatably connected to the adjacent second slide groove 514. The outer surfaces of the two screws 524 are respectively threadedly connected to the adjacent sliding plates 521.

[0053] During use, a steel plate is placed on the upper side of the center plate 523, and the double-axis motor 525 is driven by the action of the box cover 2. The double-axis motor 525 drives the screw 524, and the screw action of the screw 524 and the sliding plate 521 drives the sliding plates 521 to move closer to each other, so that the Ω-shaped pad 522 fits on the surface of the steel plate. The steel plate is clamped and fixed by the deformation of the Ω-shaped pad 522 and the friction between the screw 524 and the steel plate.

[0054] Furthermore, the honeycomb-shaped Ω-shaped pad 522 can absorb and disperse stress through the compression and expansion of the internal honeycomb structure during the deformation process. Furthermore, the synergistic effect of the rubber surface and the honeycomb structure can not only provide sufficient friction to prevent the steel plate from sliding, but also avoid damage to the surface of the steel plate. At the same time, the elastic recovery force of the honeycomb structure can enable the Ω-shaped pad 522 to quickly restore its original shape after unloading, thereby improving the reusability of the device.

[0055] Example 3. Based on Example 2, this example further distributes the air provided by the air pump 12 evenly to each aeration head 64 through the cooperation of the central tube 61, the air pipe 63, and the interlayer tube 62; the micropores of the aeration head 64 deliver the air into the cleaning liquid in the form of small bubbles, and the impact force generated by the bursting of the bubbles removes the dirt on the surface of the steel plate; the coolant circulation pipe 611 in the central tube 61 cooperates with the electric heating wire 612 to control the coolant temperature through the temperature control box 11, indirectly heating or cooling the bubbles; the agitation of the bubbles promotes material exchange and heat transfer between the cleaning liquid and the steel plate, shortens the disinfection, heating and cooling time, avoids local overheating of the steel plate or generation of internal stress, and improves the thoroughness of disinfection and pre-bending efficiency.

[0056] Specifically, in order to blow bubbles into the cleaning liquid carried by the processing chamber 17 to separate the oil and impurities on the surface of the steel plate and accelerate the heating or cooling of the steel plate, refer to Figure 9 and Figure 10 The bending auxiliary structure 6 includes a central tube 61 fixedly connected to the upper end of the mounting plate 41, and the lower parts of the outer surfaces of the two central tubes 61 are commonly fixedly connected to an air pipe 63 connected to the inner cavity thereof, and the end of the air pipe 63 away from the central tube 61 is connected to the air pump 12, and one side of the outer surface of the central tube 61 is fixedly connected to a sandwich tube 62, and the end of the sandwich tube 62 away from the central tube 61 is connected to the temperature control box 11, and the outer surfaces of the two central tubes 61 are both fixedly connected to a plurality of aeration heads 64 distributed in an array, and the plurality of aeration heads 64 are all facing the center of the mounting plate 41 and are distributed obliquely.

[0057] Furthermore, in order to heat or cool the bubbles and increase or decrease the temperature of the cleaning liquid in the processing chamber 17, see Figure 9 and Figure 10 A number of cooling liquid circulation pipes 611 are fixedly connected to the inner surface of the central tube 61 in a ring-shaped distribution, and a heating wire 612 is fixedly connected to the inner surface of each of the cooling liquid circulation pipes 611. The cooling liquid circulation pipes 611 are connected to the sandwich tube 62 and are filled with cooling liquid. A groove for increasing the heat exchange area is provided on the surface of the cooling liquid circulation pipe 611. The side of the cooling liquid circulation pipe 611 close to the sandwich tube 62 is connected to the inner ring of the sandwich tube 62, and the side of the cooling liquid circulation pipe 611 away from the sandwich tube 62 is turned back along the central tube 61 and connected to the outer ring of the sandwich tube 62. The outer surface of the heating wire 612 is covered with an insulating heat exchange coating and is connected to the heater in the temperature control box 11 through a wire.

[0058] During use, the air pump 12 continuously supplies sterilized air to the sandwich tube 62, and the central tube 61 connected to the sandwich tube 62 evenly distributes the air to each aeration head 64. The nozzles of the aeration heads 64 are provided with micropores, which can deliver the air distributed into the aeration heads 64 into the cleaning liquid in the treatment chamber 17 in the form of small bubbles.

[0059] First, in the initial stage, bubbles bombard the steel plate surface. The impact force generated when the bubbles burst can effectively remove dirt, blood or microorganisms on the steel plate surface and in the gaps, especially in grooves or threaded holes that are difficult to reach with traditional immersion disinfection, thereby improving the thoroughness of disinfection.

[0060] Further bubble movement can promote the material exchange between the disinfectant and the steel plate surface, accelerate the contact of disinfectant components and microorganisms, shorten the disinfection time, and improve the overall efficiency;

[0061] Secondly, during the bending stage, the process of bubbles rising and bursting in the liquid will cause intense convection of the disinfectant, significantly accelerating the heat transfer speed between the heated copper tube and the steel plate. When the electric heating wire 612 heats the coolant in the coolant circulation tube 611, the coolant circulation tube 611 will indirectly heat the air in the central tube 61. At this time, the air ejected by the aeration head 64 is hot air. The hot bubbles stir the liquid, causing the heat in the high-temperature area to quickly diffuse to the surface of the steel plate, reducing the heating time and improving the preheating efficiency.

[0062] In addition, the disturbance of bubbles can break the stratification phenomenon formed by temperature differences in the liquid, avoid local overheating or uneven heating of the steel plate, ensure the overall temperature of the steel plate is consistent, and provide more stable conditions for pre-bending operations.

[0063] Finally, during the low-temperature shaping stage, the movement of bubbles in the liquid can accelerate the contact and replacement between the low-temperature coolant and the surface of the steel plate, quickly taking away the heat of the steel plate. Compared with static cooling, the agitation of the bubbles allows the surface temperature of the steel plate to drop to the target value faster, shortening the cooling time and improving the efficiency of the steel plate shaping after pre-bending, thereby avoiding the generation of internal stress in the steel plate due to a sudden drop in temperature.
