Detailed Description of the Preferred Embodiments

[0030] The following Figure 1 - Figure 8 further describes the present invention in detail with reference to the accompanying

[0031] The present invention discloses an orthopedic puncture navigation device. Referring to Figures 1 - 8 , it includes a main body plate 1. Straps 2 are arranged on both sides of the main body plate 1. A fixing mechanism 3 is arranged on the strap 2, and a guiding assembly 4 is arranged on the main body plate 1; The fixing mechanism 3 includes a connecting belt 31. The connecting belt 31 is fixedly connected to one side of the binding belt 2. One end of the connecting belt 31 is fixedly connected with a plug 32. Sockets 33 are fixedly connected to both the left and right sides of the main body plate 1. The plug 32 extends into the interior of the socket 33 and matches the socket 33. The guiding component 4 includes an annular scale plate 41. The annular scale plate 41 is arranged on the top of the main body plate 1. A frame plate 42 is arranged on the top of the annular scale plate 41. Connecting plates 43 are fixedly connected to both the front and rear sides of the frame plate 42. The connecting plates 43 extend into the interior of the annular scale plate 41 and are slidably connected to the annular scale plate 41. A collar 44 is arranged inside the frame plate 42. Two shaft rods 45 are fixedly connected to the outer side of the collar 44. Both of the two shaft rods 45 are rotatably connected to the frame plate 42. A guiding tube 46 is arranged on one side of the collar 44. The guiding tube 46 penetrates through the collar 44 and is threadedly connected to the collar 44. A semi-circular scale plate 47 is arranged on one side of the frame plate 42. During puncture navigation, the binding belt 2 is strapped to the patient's body. The fixing effect after being fixed in this way is better. And compared with the clamping and fixing by a rigid plate member, the comfort level is higher. Also, since the plug 32 and the socket 33 can be flexibly disassembled, it is more conducive to the user to carry out the cleaning work of the binding belt 2. Finally, since the frame plate 42 can rotate horizontally on the annular scale plate 41, and the guiding tube 46 can also swing around the shaft rod 45 as the axis, multi-angle guiding can be carried out according to different puncture angles, improving the puncture accuracy.

[0032] One end of the binding belt 2 is fixedly connected with a soft hook surface of a magic tape 34. The other end of the binding belt 2 is fixedly connected with a loop surface of a magic tape 35. After the loop surface of the magic tape 35 and the soft hook surface of the magic tape 34 are bonded, the binding is completed. A trapezoidal block 36 is slidably connected inside the plug 32. The trapezoidal block 36 extends out of the plug 32 and the socket 33 in sequence. A reed 37 is fixedly connected inside the plug 32. The reed 37 is fixedly connected to the trapezoidal block 36. The elastic force of the reed 37 can push the trapezoidal block 36 outward. Auxiliary plates 38 are fixedly connected to both the left and right sides of the main body plate 1. Suction cups 39 are arranged at the bottoms of the auxiliary plates 38. The suction cups 39 penetrate through the auxiliary plates 38 and are fixedly connected to the auxiliary plates 38. The suction cups 39 are used for adsorbing on the patient's body to further improve the stability.

[0033] A first positioning plate is fixedly connected to the bottom of the annular scale plate 41, and the first positioning plate is fixedly connected to the top of the main body plate 1. A second positioning plate is fixedly connected between the semi-circular scale plate 47 and the frame plate 42. A limiting plate 48 is integrally formed on the outside of the guide tube 46. The limiting plate 48 is in contact with the collar 44. After the guide tube 46 is inserted into the collar 44, the limiting plate 48 limits the position. One end of one of the shaft rods 45 is fixedly connected to a swing plate 49. An arc-shaped groove is formed on the semi-circular scale plate 47. A first pointer 491 is fixedly connected to the swing plate 49. A second pointer 492 is fixedly connected to one side of the connecting plate 43. The first pointer 491 indicates the scale on the semi-circular scale plate 47, and the second pointer indicates the scale on the annular scale plate 41; A first threaded rod 493 is fixedly connected to the swing plate 49. The first threaded rod 493 passes through the arc-shaped groove. A positioning ring 494 is arranged on the outside of the first threaded rod 493. The first threaded rod 493 passes through the positioning ring 494 and is threadedly connected to the positioning ring 494. After the positioning ring 494 is tightened on the outside of the first threaded rod 493, the swing plate 49 is limited. Strip-shaped plates 495 are fixedly connected to the left and right sides of the frame plate 42. A control ring 496 is rotatably connected to the strip-shaped plates 495. A friction plate 497 is arranged at the bottom of the control ring 496. The bottom of the friction plate 497 is in contact with the top of the annular scale plate 41. A second threaded rod 498 is fixedly connected to the top of the friction plate 497. The second threaded rod 498 passes through the control ring 496 and is threadedly connected to the control ring 496. After the user manipulates the control ring 496 to rotate, the second threaded rod 498 can be driven to move up and down. A limiting plate 499 is fixedly connected to the top of the second threaded rod 498. The limiting plate 499 passes through the strip-shaped plate 495. The limiting rod limits the second threaded rod 498 to prevent the second threaded rod 498 from rotating. Four sockets 33 are provided. The four sockets 33 are symmetrically distributed in a rectangular shape on the left and right sides of the main body plate 1. The sockets 33 are used for connection with the plug blocks 32.

[0034] During the actual operation process, when this device is used, it is bound to the patient's body through the strap 2. When binding, the strap 2 is bypassed around the patient's body and tightened, and then the hook surface 35 of the magic tape is pasted with the loop surface 34 of the magic tape to complete the fixation. When fixing, ensure that the main body plate 1 stays within the range of the area to be punctured on the patient. After the strap 2 is bound, further adsorb the suction cup 39 on the patient's skin surface to further improve the stability of the main body plate 1 and avoid the possibility of its shaking, ensuring the smooth development of the navigation work; During the specific puncture navigation process, the guiding tube 46 plays a guiding role. During operation, the puncture needle is inserted into the guiding tube 46, and puncture is performed along the lumen of the guiding tube 46. In order to cope with punctures at different angles, the angle of the guiding tube 46 can be adjusted in advance. During specific adjustment, the frame plate 42 can be directly rotated. The frame plate 42 rotates inside the annular scale plate 41, and the angle reference after horizontal swing is determined by the scale indication of the second pointer 492 on the annular scale plate 41. When the appropriate angle is reached during the swing, the control ring 496 is rotated. Since the second threaded rod 498 cannot rotate with the control ring 496 under the action of the limiting plate 499, the second threaded rod 498 can be adjusted for lifting after the control ring 496 is rotated. At this time, when the second threaded rod 498 drives the friction plate 497 to descend until it tightly fits against the top of the annular scale plate 41, there is a large frictional force between the two, which can ensure the stability of the adjusted angle of the frame plate 42; After the above angle adjustment is completed, the elevation angle of the guiding tube 46 is further adjusted. During specific adjustment, the guiding tube 46 is directly swung, causing the guiding tube 46 to swing around the shaft rod 45 as the axis. At this time, the angle of the adjusted elevation of the guiding tube 46 can also be corresponded by referring to the indication of the first pointer 491 on the semi-circular scale plate 47. After the adjustment is completed, the positioning ring 494 is tightened outside the first threaded rod 493, causing the positioning ring 494 to tightly fit against the semi-circular scale plate 47. There is a large frictional force between the two, which can ensure the stability of the adjusted elevation angle of the guiding tube 46. When all the adjustment steps of the guiding tube 46 are completed, the puncture needle is passed through the guiding tube 46, and puncture is performed along the direction pointed by the guiding tube 46, which can effectively ensure the accuracy and stability of the puncture operation; After a single puncture is completed, in order to prevent the inner cavity of the guiding tube 46 from being contaminated when the puncture needle is removed, the guiding tube 46 of this device can also be directly removed, replaced or cleaned. During specific operation, the guiding rod is directly rotated and removed from the inside of the collar 44. At the same time, if the strap 2 needs to be cleaned, the trapezoidal block 36 is directly pinched and pushed into the insert block 32, and then the insert block 32 can be pulled out of the socket 33, thus completing the disassembly of the strap 2, which is convenient for cleaning and maintenance of the strap 2. Based on the above operations, the hygiene level during the use of this device can be effectively ensured, the safety during use is improved, and the situation of cross-infection is avoided.

[0035] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
