Description

Technical Field

[0002] Orthopedic diseases are pathological changes in bones, intervertebral discs, ligaments, cartilage and muscles, which in turn destroy bone integrity or compress and stimulate the spinal cord, nerves and blood vessels, resulting in a series of complex and varied clinical manifestations such as pain, motor dysfunction and deformity. Common orthopedic diseases include lumbar disc herniation, spinal or limb fractures, osteoarthritis, etc., which cause great physical and mental pain to patients.

[0003] For this reason, there are navigation surgery devices developed for minimally invasive orthopedic fractures on the market. The orthopedic navigation surgery robot is a combination of surgical instruments. It mainly includes three parts: a navigator, a robotic arm, and a display screen. The doctor observes the lesion in the patient's body through the computer screen and controls the robotic arm to perform the terminal

[0004] The navigator consists of an instrument body and a probe head. Its function is to dynamically collect and monitor the relative position changes of the patient's lesions and surgical instruments during surgery, and provide real-time feedback to help the surgeon adjust the surgical operation in a timely manner.

The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0050] like Figures 1 to 10 As shown, an embodiment of the present invention provides a minimally invasive navigation surgery device for trauma orthopedic fractures, including a base 1, a support column 3 is fixedly connected to the upper surface of the base 1, a workbench 7 is fixedly connected to the top of the support column 3, a display screen 8 is fixedly connected to the top of the workbench 7, a support frame 6 is fixedly connected to the edge of the upper surface of the base 1, a pulley frame 2 is fixedly connected to the four corners of the lower surface of the base 1, and a support component 4 for improving the stability of the device is connected to the lower surface of the base 1.

[0051] like Figure 2 and Figure 3As shown, the support assembly 4 includes an electric push rod 41 fixed on the lower surface of the base 1, the bottom of the electric push rod 41 is fixedly connected to a connecting plate 42, both sides of the connecting plate 42 are fixedly connected to storage plates 43, the inner bottom of the storage plate 43 is slidably connected to an extension plate 48, a slot 49 is provided on one side of the upper surface of the extension plate 48, and a fixing component for fixing the extension plate 48 is slidably connected to one side of the interior of the storage plate 43.

[0052] The fixed component includes a telescopic rod 45 slidably connected to the inside of the storage plate 43, the top of the telescopic rod 45 is fixedly connected to the top plate 44, the edge of the lower surface of the top plate 44 is fixedly connected to the clamping rod 410, the lower surface of the top plate 44 is fixedly connected to the adsorption component 46, one side of the clamping rod 410 is inclined near the bottom, the bottom of the clamping rod 410 extends to the inside of the clamping slot 49, the lower surface of the extension plate 48 is provided with a first groove 411, the inner surface of the first groove 411 is slidably connected to the adsorption component 46, the bottom of the inner surface of the first groove 411 on both sides is fixedly connected to the cleaning component 47, and one end of the support frame 6 is hinged with an adjustment component 5.

[0053] When the device is transferred to the designated position through the pulley frame 2, the self-locking mechanism on the pulley frame 2 is used to fix it, and the electric push rod 41 is opened to push the connecting plate 42 and the storage plate 43 to move toward the ground. The telescopic rod 45 first contacts the ground and stops moving. At this time, the storage plate 43 continues to move, and the telescopic rod 45 and the storage plate 43 slide relative to each other, and the top plate 44 drives the clamping rod 410 to move out of the inside of the clamping slot 49. At this time, the extension plate 48 can be pulled out from the inside of the storage plate 43 and unfolded, so that the storage plate 43 and the extension plate 48 contact the ground and effectively lock the device. The support makes most of the weight of the equipment concentrated on the storage plate 43 and the extension plate 48, thereby ensuring that the contact area between the equipment and the ground is increased, ensuring that the center of gravity of the equipment is more stable, and will not shake under the action of external force. When the extension plate 48 needs to be stored, one side of the extension plate 48 contacts the oblique side of the card rod 410, so that the card rod 410 moves up, and the card rod 410 slides on the surface of the extension plate 48 until the card rod 410 moves to the card slot 49. Under the action of the adsorption component 46, the card rod 410 is reset and inserted into the inside of the card slot 49 to fix the extension plate 48 for storage.

[0054] like Figure 4 and Figure 5As shown, the adsorption assembly 46 includes a mounting plate 466 sliding inside the first groove 411 and a servo motor 461 fixed on one side of the extension plate 48, two electric suction cups 467 are fixedly connected to the lower surface of the mounting plate 466, two first springs 465 are fixedly connected to the upper surface of the mounting plate 466, a triangle block 2 464 is fixedly connected in the middle of the upper surface of the mounting plate 466, a first threaded rod 462 is fixedly connected to the output end of the servo motor 461, and a triangle block 1 463 is threadedly connected to the outer surface of the first threaded rod 462.

[0055] The top of the first spring 465 is fixedly connected to the inner top of the first groove 411, and the hypotenuse of the first triangular block 463 and the hypotenuse of the second triangular block 464 are in contact with each other.

[0056] Although the storage plate 43 and the extension plate 48 are in contact with the ground, and the storage plate 43 and the extension plate 48 ensure the stability of the equipment through friction, the thrust impact force that the extension plate 48 can withstand is limited, and it will still deviate when encountering a large force, increasing the difficulty of minimally invasive surgery. At this time, the servo motor 461 is turned on to drive the first threaded rod 462 to rotate, and the first threaded rod 462 drives the triangle block 1 463 to slide on the hypotenuse of the triangle block 2 464. Since the height of the triangle block 1 463 remains unchanged, the triangle block 2 464 and the mounting plate 466 are forced to move downward, driving the electric suction cup 467 to move out from the inside of the first groove 411 and contact the ground. Then the electric suction cup 467 is turned on to work, so that the electric suction cup 467 and the ground are adsorbed on each other, thereby improving the grip of the extension plate 48 with the ground and increasing the extension plate 48's ability to withstand external thrust, thereby further ensuring the stability of the equipment.

[0057] like Figure 3 and Figure 5 As shown, the cleaning component 47 includes two air pipes 474 fixed on the inner surface of the first groove 411, an extrusion block 472 fixed on one side of the mounting plate 466, a first air pump switch 473 fixed on one side of the inner surface of the first groove 411, and a first air pump 471 fixed on one side of the extension plate 48 near the bottom, a first connecting pipe 475 is connected between the two air pipes 474, two groups of nozzles 476 are connected to the front and rear ends of the outer surfaces of the two air pipes 474, and the output end of the first air pump 471 extends to the interior of the first groove 411 and is connected to the interior of the air pipe 474.

[0058] The two groups of nozzles 476 at the same end of the outer surface of the air pipe 474 have different spray directions. The upper nozzle 476 sprays upward at forty-five degrees, and the lower nozzle 476 sprays downward at forty-five degrees.

[0059] Although the electric suction cup 467 is adsorbed to the ground, which can improve the grip of the extension plate 48 to the ground, there will be a certain amount of dust inside a general operating room. When the electric suction cup 467 is adsorbed to the ground with dust on the surface, the dust will greatly affect the adsorption force of the electric suction cup 467 and reduce the working efficiency of the electric suction cup 467. Therefore, before the electric suction cup 467 is in contact with the ground, the mounting plate 466 drives the extrusion block 472 to move, and the extrusion block 472 contacts and presses the first air pump switch 473 to turn on the first air pump 471. The first air pump 471 conveys the airflow to the inside of the air pipe 474, and the air pipe 474 is sprayed out through the nozzle 476. The upper nozzle 476 sprays the bottom of the electric suction cup 467 to remove the dust on the surface of the electric suction cup 467, and the lower nozzle 476 sprays the ground to remove the dust in the adsorption area, thereby further ensuring that the adsorption force of the electric suction cup 467 to the ground is not affected.

[0060] like Figures 6 to 9 As shown, the adjustment component 5 includes an articulated seat 51 fixed at one end of the support frame 6, the articulated seat 51 is internally hinged with an articulated block 52, the articulated seat 51 and the articulated block 52 are connected to each other by a locking bolt, one side of the articulated block 52 is slidably connected with a first guide bar 53, one side of the first guide bar 53 is fixedly connected with a slider 54, the inside of the slider 54 is slidably connected with a second guide bar 55, one side of the second guide bar 55 is fixedly connected with an optical tracker 56, a second groove 515 is opened inside the articulated block 52, the inner surface of the second groove 515 is connected with an extrusion component for fixing the first guide bar 53, one side of the optical tracker 56 is fixedly connected with a first rack 57, the inside of the second guide bar 55 is fixedly connected with a second spring 510, one side of the second spring 510 is fixedly connected with a second rack 59, the second rack 59 is meshed with the first rack 57, and the lower surface of the optical tracker 56 is fixedly connected with a dustproof component 58.

[0061] The extrusion component includes a second threaded rod 511 rotating on one side of the inner surface of the second groove 515 and a worm 513 rotating on the top of the second threaded rod 511. The outer surface of the second threaded rod 511 is fixedly connected to a worm wheel 512. The outer surface of the second threaded rod 511 is threadedly connected to an extrusion plate 514. The worm wheel 512 and the worm 513 are meshed with each other. A rubber pad is provided on one side of the extrusion plate 514.

[0062] The top of the worm 513 extends to the inside of the second groove 515 , and the top of the worm 513 is fixedly connected to the handle.

[0063] In actual surgery, the optical tracker 56 needs to change its position according to different parts and different patients, usually by directly moving the device. However, for subtle adjustments, the required precise position cannot be achieved only by moving the device, and the error is large.

[0064] According to actual needs, the optical tracker 56 is adjusted. The locking bolt is turned to loosen the hinge seat 51 and the hinge block 52, and the angle of the optical tracker 56 is adjusted. The second rack 59 is pulled apart from the first rack 57 to release the fixation of the optical tracker 56. At this time, the optical tracker 56 is pushed to make the second guide bar 55 slide inside the slider 54, and the horizontal position of the optical tracker 56 is slightly adjusted. After loosening the second rack 59, under the action of the second spring 510, the second rack 59 and the first rack 57 are meshed with each other, so that the optical tracker 56 is fixed again, and the worm 513 is turned to drive the worm wheel 512 to rotate, thereby driving the second threaded rod 511 to rotate. The rotation of the second threaded rod 511 drives the extrusion plate 514 to move away from the first guide bar 53. At this time, the first guide bar 53 can be pushed to slide inside the slider 54, and the height of the optical tracker 56 can be slightly adjusted, so that the imaging during surgery is more accurate and efficient.

[0065] like Fig.10 As shown, the dust prevention component 58 includes a cavity plate 581 fixed on the lower surface of the optical tracker 56, an air outlet 582 is provided on the upper surface of the cavity plate 581, a second connecting pipe 584 is connected to one side of the cavity plate 581, one end of the second connecting pipe 584 is connected to a second air pump 583, and the second air pump 583 is fixedly connected to one side of the optical tracker 56.

[0066] During use, the camera on the optical tracker 56 is prone to dust, and the dust will be captured and imaged on the display screen 8. The imaged dust can easily cause misjudgment by the doctor during surgery, affecting the effect and progress of the surgery. Therefore, before the surgery, the two second air pumps 583 are turned on. The second air pumps 583 blow air into the cavity plate 581 through the second connecting pipe 584 and spray it out through the two air outlets 582. The airflow sprayed from the air outlet 582 is directly in front of the camera of the optical tracker 56. When dust falls near the optical tracker 56, the airflow will blow the dust away, effectively preventing dust from falling on the camera of the optical tracker 56, thereby ensuring the cleanliness of the camera of the optical tracker 56.

[0067] The working process of the technical solution of the present invention is as follows:

[0068] First, when the device is moved to the specified position, the support component 4 can increase the contact area between the device and the ground, thereby improving the stability of the device. At the same time, the adsorption component 46 can move the electric suction cup 467 out of the first groove 411 to contact the ground and adsorb each other, thereby further improving the stability of the device. The cleaning component 47 can remove dust on the ground and the surface of the electric suction cup 467 to ensure the adsorption effect of the electric suction cup 467.

[0069] Then, by adjusting the mutual coordination between the various components of the assembly 5, the optical tracker 56 can be adjusted in horizontal and vertical height, and the optical tracker 56 can be adjusted at a fine distance to ensure that the imaging effect of the optical tracker 56 is more accurate. The dust-proof assembly 58 is set to ensure that the air flow in front of the camera of the optical tracker 56 is blown to prevent dust from falling on the camera and preventing accidental imaging caused by dust on the camera, which will affect the doctor's judgment on the operation.

[0070] 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.

[0071] 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.
