[0002] The so-called locking plate is an orthopedic device required for use in orthopedic surgery and is often used in fracture surgery. According to the shape, the plate can be divided into straight plates, S-type plates, C-type plates, etc. Different types of plates are suitable for different fracture sites. Among them, the carbon fiber locking plate is a plate made of carbon fiber material. Because carbon fiber material has excellent biocompatibility and is non-toxic, odorless, and non-irritating, it can properly adapt to the human body's humidity and temperature environment. Therefore, the carbon fiber locking plate has the advantages of safety and durability during use.

[0003] The Chinese patent application with publication number CN105213013B proposes a multi-axis locking bone plate, which includes a plate body, a locking hole, and at least two rows of teeth on the inner wall of the locking hole. The advantage is that the doctor can select a suitable angle to lock the fracture part according to the patient's fracture condition while ensuring the connection strength, which greatly improves the doctor's work efficiency.

[0004] When the above-mentioned bone plate is in use, the angle of the locking hole and the cooperation of the row of teeth can achieve the purpose of selecting the appropriate angle for installation according to the individual conditions of different patients, which is helpful to improve work efficiency to a certain extent. However, in actual surgical applications, since the bone plate is fixedly installed on the patient's bone, the above-mentioned device is similar to the existing bone plate structure, and the holes and grooves opened thereon are fixed positions. This leads to that during the operation, if it is necessary to drill holes in different positions according to the patient's conditions, drilling holes in different positions can only be achieved by replacing the bone plate, which is not flexible enough to use. Therefore, a carbon fiber locking bone plate is proposed here to solve the above problems. Summary of the invention

[0029] The following is combined with Figure 1 -Attached Fig.10 The present invention is described in further detail.

[0030] The present invention discloses a carbon fiber locking bone fracture plate, comprising a bone fracture plate body 1, a through slot 2 is provided on the bone fracture plate body 1, a positioning seat 3 is slidably connected inside the through slot 2, and a positioning mechanism 4 is provided on the positioning seat 3; The positioning mechanism 4 includes a positioning screw 41, which is arranged on the top of the positioning seat 3. An auxiliary groove 42 is opened on the top of the bone plate body 1. The auxiliary groove 42 is arranged on the top of the through groove 2 and is connected to the through groove 2. A first gasket 43 is arranged on the outside of the positioning screw 41. The positioning screw 41 passes through the first gasket 43. The positioning screw 41 passes through the auxiliary groove 42 and extends into the through groove 2. The bottom of the first gasket 43 fits with the inner side of the auxiliary groove 42. The positioning screw 41 passes through the positioning seat 3 and is connected to the positioning seat 3 by threads. The bottom end of the positioning screw 41 fits with the inner wall of the through groove 2. A mounting hole 44 is provided on the positioning seat 3, and a bone screw 45 is provided on the top of the positioning seat 3. The bone screw 45 passes through the mounting hole 44 and matches with the mounting hole 44. When the bone fracture site of the patient is set using the bone fracture plate body 1, the insertion position of the bone screw 45 needs to be adjusted according to the patient's condition. The positioning seat 3 can be directly moved inside the bone fracture plate body 1. The insertion position of the subsequent bone screw 45 can be adjusted by adjusting the position of the positioning seat 3. Compared with the traditional fixed hole position, it is more flexible to use, the adjustment process is simple and convenient, and the operation threshold is lower.

[0031] The positioning mechanism 4 includes a guide assembly, which includes a guide cylinder 46. The guide cylinder 46 is arranged on the top of one of the positioning seats 3. A guide strip 47 is integrally formed on the inner wall of the guide cylinder 46. A second gasket 48 is rotatably connected to the outside of the bone screw 45. A guide groove 49 is provided on the second gasket 48. The guide strip 47 matches the guide groove 49. Two card slots 491 and two slots 492 are respectively provided on the positioning seat 3. When the bone screw 45 is screwed in, the guide cylinder 46 can be pre-installed on the top of the corresponding positioning seat 3. The guide cylinder 46 is perpendicular to the positioning seat 3. When the bone screw 45 is subsequently placed, the guide strip 47 will provide guidance for the second gasket 48. At this time, the bone screw 45 can be screwed in vertically. This operation can effectively avoid the situation where the bone screw 45 is tilted at an angle when being screwed in. The left and right sides of the guide cylinder 46 are fixedly connected with card plates 493, and the two card plates 493 extend into the two card slots 491 respectively, and the card plates 493 match the card slots 491. After the card plates 493 are inserted into the card slots 491, they fit into the card slots 491. A control block 494 is slidably connected to the card plate 493. A card block 495 is integrally formed at the bottom of the control block 494. The card block 495 and the control block 494 both extend out of the card plate 493. A spring 496 is fixedly connected to the card plate 493. The spring 496 is fixedly connected to one side of the control block 494. The spring 496 exerts an elastic force on the control block 494. Therefore, after the card plate 493 is inserted into the card slot 491 and the card block 495 extends out of the card plate 493, the guide cylinder 46 is fixedly installed. Insert plates 497 are fixedly connected to the front and rear sides of the guide cylinder 46. The two insert plates 497 extend into the two slots 492 respectively and match the slots 492. After the insert plates 497 extend into the slots 492, they can further provide auxiliary limiting for the guide cylinder 46, providing support force for the guide cylinder 46 in the front and rear directions, so as to improve the stability of the guide cylinder 46 after installation.

[0032] A spreading mechanism 5 is also provided on the top of the bone fracture plate body 1. The spreading mechanism 5 includes two supporting plates 51. The two supporting plates 51 are both provided on the top of the bone fracture plate body 1. Two connecting plates 52 are fixedly connected between the two supporting plates 51. The bottoms of the two connecting plates 52 are fixedly connected with mounting plates 53. Two mounting grooves 54 are provided on the top of the bone fracture plate body 1. The two mounting plates 53 extend into the inside of the two mounting grooves 54 respectively, and the mounting plates 53 match the mounting grooves 54. When the mounting plates 53 are inserted into the inside of the mounting grooves 54, the fixing plates 57 extend into the inside of the mounting grooves 54 to complete the installation and fixing of the mounting plates 53. The mounting plate 53 is slidably connected to a control plate 55, and a pressing plate 56 is integrally formed on the top of the control plate 55. The pressing plate 56 penetrates the connecting plate 52. The mounting plate 53 is slidably connected to two fixing plates 57, and the two fixing plates 57 extend out of the two sides of the mounting plate 53 respectively. An intermediate plate 58 is fixedly connected to the bottom wall of the inner cavity of the mounting plate 53, and the intermediate plate 58 is arranged between the two fixing plates 57. The user can press the pressing plate 56 to further adjust and control the control plate 55. A push-pull rod 59 is provided between the control plate 55 and the fixed plate 57. Both ends of the push-pull rod 59 extend into the inside of the control plate 55 and the fixed plate 57 respectively, and the push-pull rod 59 is connected to the control plate 55 and the fixed plate 57 respectively through a rotating shaft. After the control plate 55 is lifted or lowered, the push-pull rod 59 can be driven to flip, and then the push-pull rod 59 pushes and pulls the fixed plate 57 horizontally. A spring 591 is fixedly connected to the top of the middle plate 58. The top of the spring 591 is fixedly connected to the inner side of the control plate 55, and the spring 591 provides an elastic force on the control plate 55.

[0033] In actual operation, when the device is used, the drilling position can be adjusted according to the patient's condition before the bone plate body 1 is installed. When adjusting, the positioning seat 3 is directly moved inside the through groove 2. When the positioning seat 3 is moved to a suitable position, the positioning screw 41 is turned and tightened. When the positioning screw 41 is turned, the first gasket 43 is driven to move until the first gasket 43 is tightly fitted with the inner wall of the auxiliary groove 42. At the same time, the bottom end of the positioning screw 41 is also tightly fitted with the inner wall of the through groove 2. The positioning seat 3 can maintain the adjusted posture and can properly adapt to the screwing requirements of the bone screws 45 at different positions. Compared with traditional devices, the flexibility of use is improved, which provides greater convenience for bone setting surgery. Specifically, when screwing the bone screw 45 into the patient's bone, in order to ensure that the bone screw 45 can be screwed in perpendicular to the positioning seat 3, and the bone screw 45 will not be tilted due to the screwing angle not being properly controlled, thereby causing adverse effects, a guide cylinder 46 can be installed on the corresponding positioning seat 3. During the specific installation, the control block 494 is pinched until it moves into the inside of the card plate 493. At this time, the control block 494 drives the card block 495 to also enter the inside of the card plate 493, and then the guide cylinder 46 is directly installed. The card plate 493 on the 6 is aligned with the card slot 491, and the plug plate 497 is aligned with the slot 492, and then they can be inserted. When the card plate 493 and the card slot 491 enter the card slot 491 and the slot 492 to the maximum depth, the control block 494 is stopped from being pinched. At this time, due to the elastic force of the spring 496 pushing the control block 494, the control block 494 and the card block 495 are prompted to move out of the card plate 493, and the card block 495 moves to contact with the inside of the card slot 491, and the installation of the guide cylinder 46 is completed; After the guide cylinder 46 is installed, the bone screw 45 is placed into the guide cylinder 46. During the placement process, ensure that the guide strip 47 passes through the guide groove 49 on the second gasket 48, so as to provide a limit for the second gasket 48, so that it can maintain a stable vertical movement of the positioning seat 3. Correspondingly, the bone screw 45 inside the second gasket 48 can also maintain a vertical state of movement. At this time, the bone screw 45 is controlled to be screwed in to ensure that the angle of the bone screw 45 is vertical, so that the installation quality of the bone screw 45 will not be affected due to the tilt of the angle. At the same time, after the bone screw 45 is installed, after repeating the above operation of pinching the control block 494, the control block 494 drives the clamping block 495 to move to the inside of the clamping plate 493. At this time, the guide cylinder 46 can be directly removed from the positioning seat 3. The operation process is simple and convenient, and will not add operating pressure to the surgical process; Finally, since the bone fracture body 1 is directly operated on the fracture site, it is inevitable that the skin and flesh outside the bone will be cut during the operation. In addition, when installing the bone fracture body 1, in order to avoid the closure of the cut skin and flesh and interference with the operation of the bone fracture body 1, a support plate 51 can also be installed on the bone fracture body 1. During the specific installation, the pressing plate 56 is pushed toward the mounting plate 53, and the mounting plate 53 drives the control plate 55 to move. The control plate 55 drives the push-pull rod 59 to flip. After the push-pull rod 59 flips, it drives the fixing plate 57 to move horizontally until it enters the mounting plate 53. The mounting plate 53 can be directly inserted into the mounting groove 54. After insertion, due to the elastic force of the spring 591, the control plate 55 is pushed back toward the direction of the connecting plate 52. It can be seen from the above operation that at this time, the two fixing plates 57 extend out of the mounting plate 53 and enter the mounting groove 54 again, and the installation of the support plate 51 is completed. The support plate 51 is at the top of the plate with its top tilted toward the outside of the plate body 1, and the corresponding flesh and skin are in contact with the inwardly tilted lower part of the support plate 51, so that the distance for turning the flesh and skin open can be minimized as much as possible, thereby further reducing the situation of tearing the flesh and skin. At the same time, since the top opening of the space formed by the two support plates 51 is relatively large, a larger operating space is provided for operations such as screwing in the bone screws 45, thereby ensuring the smooth progress of the operation. Compared with the traditional operation of turning the flesh and skin open manually or with the help of additional tools, it is more convenient.

[0034] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
