Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an orthopedic saw dedicated to orthopedic surgery. Background Art

[0002] Orthopedics is one of the most common departments in major hospitals, mainly studying the anatomy, physiology and pathology of the musculoskeletal system, and using drugs, surgery and physical methods to maintain and develop the normal form and function of this system. An orthopedic saw is usually required during orthopedic surgery treatment.

[0003] For traditional orthopedic saws, the saw handle needs to be continuously pulled back and forth to drive the orthopedic saw to move and cut the bone. A certain stroke of the orthopedic saw is required to ensure the cutting quality.

[0004] To solve the above problems, the application number CN115634005A discloses a multifunctional orthopedic saw dedicated to orthopedic surgery. Through the setting of wire cutting, the stroke of cutting the bone is avoided, and the space occupation is reduced; through the setting of reciprocating wire winding sawing, there is no need to hold and swing left and right, improving the convenience of operation.

[0005] However, when the cutting wire cuts the bone, a certain angle needs to be maintained between the cutting saw and the bone to effectively cut the bone. However, during the operation, when the cutting angle is tricky and the cutting position is below, the patient needs to be turned over, increasing the steps and difficulty during the operation and the discomfort of the patient.

[0021] By setting the replacement component, the original cutting area of the cutting wire is replaced, and the unused area of the cutting wire is swapped to between the two hinge frames. This not only ensures the cutting effect of the cutting wire but also avoids excessive wear on the cutting area of the cutting wire, preventing the cutting wire from breaking during the operation and hindering the progress of the operation. At the same time, it can maximize the utilization rate of the cutting wire, increase the service life of the cutting wire, reduce the loss of the cutting wire, and can quickly replace the cutting wire.

[0022] By setting up the storage component, the torque force generated by the coil spring drives the winding shaft to rotate, so as to wind and store the end of the cutting wire by rotation, effectively avoiding the random swinging of the end of the cutting wire, scratching the patient's skin, avoiding the influence on the doctor during the operation, and improving the quality of the operation.

[0046] As Figures 1 to 7 shown, an orthopedic saw dedicated to orthopedic surgery provided by an embodiment of the present invention includes a mounting plate 1, a handle 2 is fixedly connected to one side of the mounting plate 1, and fixing frames 3 are symmetrically arranged on the other side of the mounting plate 1. A rotatable assembly 4 with adjustable angle is hinged to one side of the fixing frame 3.

[0047] As Figures 1 to 3 shown, the rotatable assembly 4 includes a fixed column 43 fixed to one side of the fixing frame 3, a servo motor 412 fixed to the middle of one side of the fixing frame 3, and a receiving assembly 49 rotatably arranged at the middle of one side of the fixing frame 3. A connecting plate 42 is rotatably connected to the outer surface of the fixed column 43. One end of the connecting plate 42 is fixedly connected to a hinge frame 41. A through hole 44 is formed in the fixed column 43. A magnet 45 is slidably connected to the inside of the through hole 44. A second annular rack 47 is fixedly connected to one side of the magnet 45. A first annular rack 46 is fixedly connected to one side of the connecting plate 42. Limiting roller groups 410 are rotatably connected to one side of the inner surface of the connecting plate 42 and one side of the inner surface of the fixing frame 3. A guiding roller 413 is rotatably connected to the inner bottom of the hinge frame 41. The output end of the servo motor 412 is connected to a swapping assembly 48, and a cutting wire 411 for cutting bones is connected to the inside of the swapping assembly 48.

[0048] The limiting roller groups 410 include two limiting rollers arranged one above the other, and guiding grooves are formed on the outer surfaces of the limiting rollers. The fixed column 43 passes through the inside of the first annular rack 46. The second annular rack 47 and the magnet 45 are meshed with each other. The fixed column 43 is made of metallic iron. A splash-proof assembly 5 for collecting bone chips is arranged at one edge of one side of the hinge frame 41.

[0049] When performing orthopedic surgery on a patient, when cutting the bone under the lying patient, in order to reduce the adjustment of the patient's posture and reduce the discomfort of the patient, at this time, the shape of the orthopedic saw is changed. The magnet 45 is pulled to slide to one side inside the through hole 44 to drive the second annular rack 47 to move. The second annular rack 47 moves away from the first annular rack 46 to release the fixed state. At this time, the articulated frame 41 can be rotated. The articulated frame 41 drives the connecting plate 42 to rotate around the fixed column 43. An appropriate angle is formed between the articulated frame 41 and the fixed frame 3. Under the limitation of the two limiting roller groups 410, the cutting wire 411 smoothly forms a broken line. The cutting wire 411 wound around the replacement component 48 will also extend a certain length to ensure the smooth adjustment of the angle of the articulated frame 41. At this time, the articulated frame 41 can be fixed. The magnet 45 is moved closer to the first annular rack 46, so that the first annular rack 46 and the second annular rack 47 are meshed again. The magnet 45 is adsorbed and fixed to one side inside the through hole 44, so as to fix the second annular rack 47, so that the articulated frame 41 and the connecting plate 42 no longer rotate, thus successfully completing the angle adjustment. Therefore, when facing a cutting angle with a tricky angle, only the angle of the cutting wire 411 needs to be adjusted, avoiding continuous adjustment of the patient's posture, reducing the pain and discomfort of the patient during the operation, and effectively improving the practicability and convenience of the orthopedic saw.

[0050] As Figure 4 shown, the replacement component 48 includes a rotating screw 481 fixed to the output end of the servo motor 412. A first card slot 482 is opened inside the rotating screw 481. A nut 483 is threadedly connected to the outer surface of the first card slot 482. Receiving grooves 486 are symmetrically opened on the outer surface of the rotating screw 481. A trapezoidal block 484 is slidably connected inside the receiving groove 486. A clamping plate 485 is arranged on one side of the two trapezoidal blocks 484 close to each other.

[0051] The clamping plate 485 is located inside the first card slot 482, and an anti-slip pattern is arranged on one side of the clamping plate 485.

[0052] During orthopedic surgery, in the area where the cutting wire 411 is in long-term contact with the bone for cutting, there will be a certain degree of wear, causing the surface of the cutting area of the cutting wire 411 to become relatively smooth. The strength of its cutting area will drop sharply, making it prone to breakage. At this time, to ensure the cutting effect, it is necessary to replace the cutting area of the cutting wire 411. At this time, the positions of both ends of the cutting wire 411 need to be adjusted. Rotate the nut 483 to move it away from the outside of the trapezoidal block 484, release the fixation of the trapezoidal block 484, and thus release the fixation of the clamping plate 485 on the cutting wire 411. At this time, after pulling out a certain length of one end of the cutting wire 411 from the outer surface of the rotating screw 481, rotate the nut 483 to move towards the trapezoidal block 484. The nut 483 contacts and presses against the hypotenuse of the trapezoidal block 484. The two trapezoidal blocks 484 drive the clamping plate 485 to press the cutting wire 411, pull the other end of the cutting wire 411 to slide a certain distance inside another first card slot 482 and tighten the cutting wire 411, and then fix the cutting wire 411. At this time, the original cutting area of the cutting wire 411 will be replaced, and the unused area of the cutting wire 411 will be swapped to between the two hinge brackets 41. This not only ensures the cutting effect of the cutting wire 411 but also avoids excessive wear on the cutting area of the cutting wire 411, preventing breakage during the operation and hindering the progress of the operation. At the same time, it can maximize the utilization rate of the cutting wire 411, increase the service life of the cutting wire 411, reduce the loss of the cutting wire 411, and quickly replace the cutting wire 411.

[0053] As Figure 5 shown, the storage assembly 49 includes a support shaft 491 fixed to one side of the inner surface of the fixed frame 3. A coil spring 492 is arranged on the outer surface of the support shaft 491. One side of the support shaft 491 is fixedly connected to a circular plate 494. A jack 496 is opened on one side of the circular plate 494. A winding shaft 493 is rotatably connected to the middle of one side of the circular plate 494. A second card slot 497 is opened in the middle of the winding shaft 493. A plug rod 495 is slidably arranged at the edge of the inside of the winding shaft 493.

[0054] One side of the plug rod 495 extends into the inside of the jack 496, and the centers of the winding shaft 493 and the rotating screw 481 are at the same horizontal height.

[0055] Two servo motors 412 drive the rotating screw 481 to rotate forward and backward synchronously. The two clamping plates 485 fix both ends of the cutting wire 411, thereby driving the cutting wire 411 to continuously move back and forth to cut the bone. The cutting wire 411 is fixed by the clamping plates 485, and the part behind the fixed point of the cutting wire 411 cannot be fixed and will swing as the rotating screw 481 rotates continuously. The swinging cutting wire 411 not only affects the operation of the doctor but also scratches the patient's skin and tissues. Therefore, it is necessary to store the end of the cutting wire 411. At this time, the insertion rod 495 is pulled out from the inside of the insertion hole 496 to release the fixing effect between the winding shaft 493 and the circular plate 494. At this time, the outermost end of the cutting wire 411 is stuck inside the second card slot 497, and the winding shaft 493 is rotated to wind the cutting wire 411. After winding, the insertion rod 495 is inserted into the inside of the insertion hole 496 to fix the winding shaft 493 and the circular plate 494. When the rotating screw 481 rotates, it will pull the end of the cutting wire 411, causing the winding shaft 493, the circular plate 494, and the support shaft 491 to rotate synchronously, twisting the torsion spring 492. When the rotating screw 481 rotates in the reverse direction, the torque force generated by the torsion spring 492 drives the winding shaft 493 to rotate, and the cutting wire 411 is rotated and wound again for storage, effectively avoiding the random swing of the end of the cutting wire 411, scratching the patient's skin, avoiding the influence on the doctor during the operation, and improving the quality of the operation.

[0056] As Figure 6 and Figure 7 shown, the anti-spray component 5 includes an adjustment component 53 that slides on the side edge of one side of the hinge frame 41. A moving plate 51 is arranged on the adjustment component 53. A rotating cylinder 510 is rotatably connected inside the moving plate 51. A cleaning sponge 59 is arranged on the inner surface of the rotating cylinder 510. A worm gear 511 is fixedly connected to the outer surface of the rotating cylinder 510. A middle part on one side of the moving plate 51 is fixedly connected with an internally threaded sleeve 56. An externally threaded cylinder 54 is threadedly connected to the inner surface of the internally threaded sleeve 56. A round hole 55 is opened on one side of the externally threaded cylinder 54. A worm 57 is rotatably connected to the edge of the moving plate 51 far away from the externally threaded cylinder 54. Gears 58 are arranged on the top of the worm 57, the outer surface of the guide roller 413, and the adjustment component 53. A synchronous belt 52 is sleeved on the outer surfaces of the three gears 58.

[0057] The worm 57 and the worm gear 511 are meshed with each other. One side of the rotating cylinder 510 is located inside the externally threaded cylinder 54. The cutting wire 411 passes through the inside of the rotating cylinder 510, the round hole 55, and the cleaning sponge 59. The inner surface of the cleaning sponge 59 is closely attached to the outer surface of the cutting wire 411.

[0058] When the cutting wire 411 cuts the bone, a large amount of bone debris will be generated. The bone debris will splash to various areas of the operating table driven by the cutting wire 411, and will also be scattered on the patient's human tissue, which is easy to cause infection. Therefore, when the cutting wire 411 cuts, the movement of the cutting wire 411 will drive the guide roller 413 to rotate continuously, and the guide roller 413 drives a gear 58 to rotate. The gear 58 drives the other two gears 58 to rotate at the same time through the transmission of the synchronous belt 52. The gear 58 drives the worm 57 to rotate, and the worm 57 drives the rotating cylinder through the worm wheel 511 510 and the cleaning sponge 59 rotate. When the cutting wire 411 moves back and forth, the rotating cleaning sponge 59 continuously wipes the bone fragments carried on the surface of the cutting wire 411, and the wiped bone fragments fall into the interior of the external threaded cylinder 54 for collection. The rotating cleaning sponge 59 can wipe the surface of the cutting wire 411 more comprehensively and effectively, which can not only prevent the cutting wire 411 from carrying bone fragments and scattering them everywhere, but also prevent the rough texture on the surface of the cutting wire 411 from being filled with bone fragments, which greatly reduces the cutting effect, thus killing two birds with one stone.

[0059] like Figure 6 As shown, the adjustment assembly 53 includes a threaded sleeve 531 rotated at the edge of one side of the articulated frame 41 and a through slot 533 opened on the upper surface of the articulated frame 41, the interior of the through slot 533 is slidably connected to a slider 534, the internal thread of the threaded sleeve 531 is threadedly connected to a threaded rod 532, one side of the threaded rod 532 passes through the articulated frame 41 and slides with each other, and the movable plate 51 is fixedly connected to one side of the threaded rod 532.

[0060] The slider 534 is in an I-shape, and a locking bolt is threadedly connected to the upper surface of the slider 534 , and a gear 58 is rotatably connected to the bottom of the slider 534 .

[0061] Since the bone cutting positions required in orthopedics are not the same, the sizes of the cutting areas of the cutting wire 411 are also different. If the cutting area is small, the distance between the two cleaning sponges 59 is too large, and the position cut by the cutting wire 411 cannot be effectively cleaned, which reduces the cleaning effect of the cleaning sponge 59. At this time, rotating the threaded sleeve 531 drives the threaded rod 532 to move inside the hinged frame 41, driving the two moving plates 51 to approach each other, thereby driving the cleaning sponges 59 to approach each other along the cutting wire 411. At this time, the gear 58 on the worm 57 will pull one end of the synchronous belt 52 to move, ensuring that the moving plate 51 moves smoothly, and the slider 534 will slide inside the through groove 533 to approach the guide roller 413. When the two cleaning sponges 59 reach the appropriate position, the locking bolt is rotated to fix the slider 534, so that the positions of the two cleaning sponges 59 can be adjusted according to the size of the bone cut during the operation, thereby ensuring the cleaning effect of the cleaning sponge 59 to the greatest extent.

[0062] The working process of the technical solution provided by the present invention is as follows:

[0063] First, according to the position of the patient's bone cutting, the shape of the orthopedic saw is adjusted. By sliding the connecting plate 42 on the outer surface of the fixed column 43, the angle of the articulated frame 41 is adjusted. Through the engagement of the second annular rack 47 and the first annular rack 46, the articulated frame 41 is effectively fixed to complete the angle adjustment. Pull the cutting wire 411 to move the cutting area out from between the two articulated frames 41 and fix it through the clamping plate 485, so as to avoid excessive local wear of the cutting wire 411 and cause accidental breakage of the cutting wire 411 during the operation, effectively extending the service life of the cutting wire 411. By winding the end area of the cutting wire 411 with the winding shaft 493, it can be avoided that the end of the cutting wire 411 swings randomly with the rotation of the rotating screw 481.

[0064] Then, when the cutting wire 411 is cutting, through the transmission between the gear 58 and the synchronous belt 52, the cleaning sponge 59 can be driven to rotate to clean the bone debris on the surface of the cutting wire 411. The external thread cylinder 54 effectively collects the bone debris. The threaded connection between the external thread cylinder 54 and the internal thread sleeve 56 can remove the external thread cylinder 54 at any time to clean its interior. With the cooperation of the components of the adjustment assembly 53, the position of the cleaning sponge 59 can be effectively adjusted.

[0065] The present invention covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present invention.

However, those skilled in the art can fully understand the present invention without these detailed descriptions.
