[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. Orthopedic saws are usually required for orthopedic surgical treatment.

[0003] Traditional orthopedic saws require the saw handle to be pulled back and forth continuously to drive the orthopedic saw to move and cut bones. A certain orthopedic saw stroke is required to ensure the quality of the sawing.

[0004] To solve the above problems, application number CN115634005A discloses a multifunctional orthopedic saw specially used for orthopedic surgery. The device avoids the travel of sawing bones and reduces space occupancy through the setting of wire cutting. The setting of reciprocating winding wire cutting saw eliminates the need to hold and swing left and right, thereby improving the convenience of operation.

[0005] However, when the cutting wire is cutting the bone, it is necessary to ensure that there is a certain angle between the cutting saw and the bone in order to effectively cut the bone. However, if the cutting angle is tricky during the operation and the cutting position is located below, the patient needs to be turned over, which increases the steps and difficulty of the operation and increases the patient's discomfort.

[0046] like Figures 1 to 7 As shown, an embodiment of the present invention provides an orthopedic saw specially used for orthopedic surgery, including a mounting plate 1, a handle 2 is fixedly connected to one side of the mounting plate 1, a fixing frame 3 is symmetrically arranged on the other side of the mounting plate 1, and a rotating component 4 with adjustable angle is hinged on one side of the fixing frame 3.

[0047] like Figures 1 to 3 As shown, the rotating assembly 4 includes a fixed column 43 fixed on one side of the fixed frame 3, a servo motor 412 fixed in the middle of one side of the fixed frame 3 and a storage assembly 49 rotatably arranged in the middle of one side of the fixed frame 3, the outer surface of the fixed column 43 is rotatably connected to a connecting plate 42, one end of the connecting plate 42 is fixedly connected to an articulated frame 41, a through hole 44 is provided inside the fixed column 43, a magnet 45 is slidably connected inside the through hole 44, one side of the magnet 45 is fixedly connected to a second annular rack 47, one side of the connecting plate 42 is fixedly connected to a first annular rack 46, one side of the inner surface of the connecting plate 42 and one side of the inner surface of the fixed frame 3 are both rotatably connected to a limiting roller group 410, the bottom of the articulated frame 41 is rotatably connected, the output end of the servo motor 412 is connected to a switching assembly 48, and the inside of the switching assembly 48 is connected to a cutting wire 411 for cutting bones.

[0048] The limiting roller group 410 includes two limiting rollers arranged one above and one below, and a guide groove is provided on the outer surface of the limiting roller. The fixed column 43 passes through the interior of the first annular rack 46, and the second annular rack 47 and the magnet 45 are engaged with each other. The material of the fixed column 43 is metal iron, and a splash-proof component 5 for collecting bone fragments is provided at the edge of one side of the articulated frame 41.

[0049] When performing orthopedic surgery on a patient and cutting the bone below a lying patient, in order to reduce the need for posture adjustment on the patient and reduce the patient's discomfort, the shape of the orthopedic saw is changed at this time, and the magnet 45 is pulled to slide to one side inside the through hole 44 to drive the second annular rack 47 to move, and the second annular rack 47 and the first annular rack 46 move away from each other to release the fixed state. At this time, the articulated frame 41 can be rotated, and the articulated frame 41 drives the connecting plate 42 to rotate around the fixed column 43, and a suitable angle is formed between the articulated frame 41 and the fixed frame 3. The cutting wire 411 is limited by the two limiting roller groups 410 to form a smooth broken line, and the cutting wire 411 wound on the exchange component 48 will also The articulated frame 41 is extended to a certain length to ensure that the angle of the articulated frame 41 can be adjusted smoothly. At this time, the articulated frame 41 can be fixed, and the magnet 45 is moved close to the first annular rack 46, so that the first annular rack 46 and the second annular rack 47 are re-engaged, and the magnet 45 and one side of the inside of the through hole 44 are adsorbed and fixed to each other, thereby fixing the second annular rack 47, so that the articulated frame 41 and the connecting plate 42 no longer rotate, thereby successfully completing the angle adjustment. Therefore, when facing a tricky cutting angle, it is only necessary to adjust the angle of the cutting wire 411, avoiding the patient's constant posture adjustment, reducing the patient's pain and discomfort during surgery, and effectively improving the practicality and convenience of the orthopedic saw.

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

[0051] The clamping plate 485 is located inside the first clamping slot 482 , and one side of the clamping plate 485 is provided with anti-slip grooves.

[0052] During orthopedic surgery, the area where the cutting wire 411 is in contact with the bone for a long time will be worn, causing the surface of the cutting area of ​​the cutting wire 411 to become relatively smooth, and the strength of the cutting area will drop sharply, which is prone to breakage. At this time, in order to ensure the cutting effect, the area cut by the cutting wire 411 needs to be replaced. At this time, the positions of the two ends of the cutting wire 411 need to be adjusted, and the nut 483 is rotated to move away from the outside of the trapezoidal block 484 to release the fixation of the trapezoidal block 484, thereby releasing the fixation of the cutting wire 411 by the clamping plate 485. At this time, after the cutting wire 411 at one end is pulled out of the outer surface of the rotating screw 481 for a certain length, the nut 483 is rotated to move toward the trapezoidal block 484, and the nut 483 and the hypotenuse of the trapezoidal block 484 contact and squeeze each other, and the two The trapezoidal block 484 drives the card plate 485 to squeeze the cutting wire 411, pulls the other end of the cutting wire 411 to make it slide a certain distance inside the other first card slot 482 and tightens the cutting wire 411, and then fixes 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 replaced between the two articulated frames 41, which not only ensures the cutting effect of the cutting wire 411, but also avoids excessive wear of the cutting area of ​​the cutting wire 411, causing breakage during surgery and hindering the progress of the surgery. 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] like Figure 5 As shown, the storage component 49 includes a support shaft 491 fixed to one side of the inner surface of the fixed frame 3, a coil spring 492 is provided on the outer surface of the support shaft 491, a circular plate 494 is fixedly connected to one side of the support shaft 491, a plug hole 496 is provided 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 provided in the middle of the winding shaft 493, and an insertion rod 495 is slidably provided at the edge of the winding shaft 493.

[0054] One side of the insertion rod 495 extends to the inside of the insertion hole 496, and the winding shaft 493 and the center of the rotating screw 481 are at the same horizontal height.

[0055] The two servo motors 412 drive the rotating screw 481 to rotate forward and backward synchronously, and the two ends of the cutting wire 411 are fixed by two clamping plates 485, so as to drive the cutting wire 411 to move back and forth continuously to cut the bone. The cutting wire 411 is fixed by the clamping plates 485, while the part at the rear end of the fixing point of the cutting wire 411 cannot be fixed and will swing with the continuous rotation of the rotating screw 481. The swinging cutting wire 411 not only affects the doctor's operation, but also causes scratches on the patient's skin and tissue. Therefore, the end of the cutting wire 411 needs to be stored. At this time, the insertion rod 495 is pulled out from the inside of the insertion hole 496 to release the fixing effect of the reel 493 and the circular plate 494. At this time, the end of the cutting wire 411 is The card is stuck inside the second card slot 497, and the reeling 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 reeling shaft 493 and the circular plate 494. When the rotating screw 481 rotates, the end of the cutting wire 411 will be pulled, so that the reeling shaft 493, the circular plate 494 and the support shaft 491 rotate synchronously, and the coil spring 492 is twisted. When the rotating screw 481 is reversed, the torque force generated by the coil spring 492 drives the reeling shaft 493 to rotate, and the cutting wire 411 is rotated and wound for storage again, which effectively prevents the end of the cutting wire 411 from swinging randomly and causing scratches on the patient's skin, avoids the impact on the doctor during surgery, and improves the quality of the surgery.

[0056] like Figure 6 and Figure 7 As shown, the splash-proof assembly 5 includes an adjusting assembly 53 that slides at the edge of one side of the articulated frame 41, a movable plate 51 is arranged on the adjusting assembly 53, the movable plate 51 is internally rotatably connected with a rotating cylinder 510, the inner surface of the rotating cylinder 510 is provided with a cleaning sponge 59, the outer surface of the rotating cylinder 510 is fixedly connected with a worm gear 511, an internal threaded sleeve 56 is fixedly connected to the middle of one side of the movable plate 51, the inner surface of the internal threaded sleeve 56 is threadedly connected with an external threaded cylinder 54, a circular hole 55 is opened on one side of the external threaded cylinder 54, a worm 57 is rotatably connected to the edge of the movable plate 51 away from the external threaded cylinder 54, gears 58 are arranged on the top of the worm 57, the outer surface of the guide roller 413 and the adjusting assembly 53, and the outer surfaces of the three gears 58 are sleeved with synchronous belts 52.

[0057] The worm 57 and the worm wheel 511 mesh with each other. One side of the rotating cylinder 510 is located inside the external threaded cylinder 54. The cutting wire 411 passes through the rotating cylinder 510, the circular hole 55 and the cleaning sponge 59. The inner surface of the cleaning sponge 59 fits tightly with 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 workflow of the technical solution provided by the present invention is as follows:

[0063] First, the shape of the orthopedic saw is adjusted according to the position of the patient's bone cutting. The connecting plate 42 is slid on the outer surface of the fixed column 43 to adjust the angle of the articulated frame 41. The second annular rack 47 and the first annular rack 46 are engaged to effectively fix the articulated frame 41 to complete the angle adjustment. The cutting wire 411 is pulled to move the cutting area out from between the two articulated frames 41 and fixed by the clamping plate 485. This can avoid excessive local wear of the cutting wire 411, which may cause accidental breakage of the cutting wire 411 during surgery, and effectively extend the service life of the cutting wire 411. The area at the end of the cutting wire 411 is wound around the winding shaft 493 to avoid the end of the cutting wire 411 from swinging randomly with the rotation of the rotating screw 481.

[0064] Then, when the cutting wire 411 is cutting, the transmission between the gear 58 and the synchronous belt 52 can drive the cleaning sponge 59 to rotate, and the bone debris on the surface of the cutting wire 411 can be cleaned. The externally threaded cylinder 54 effectively collects the bone debris. The threaded connection between the externally threaded cylinder 54 and the internally threaded sleeve 56 allows the externally threaded cylinder 54 to be removed at any time to clean its interior. The cooperation between the various components of the adjustment assembly 53 can effectively adjust the position of the cleaning sponge 59.

[0065] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
