Description

Technical Field

[0001] This utility model relates to the field of bone plate technology, specifically to an adjustable-size bone plate for orthopedics. Background Technology

[0002] Bone plates are perforated plate-shaped medical devices used in orthopedic surgery for internal fixation of fractures. They form a stable connection with the bone through screws to promote healing.

[0003] CN219331863U discloses a size-adjustable rib metal bone plate, which includes a metal bone plate body and an adjusting fastening plate. The metal bone plate body includes a middle bone plate, a first side bone plate, and a second side bone plate. One end of the first side bone plate is embedded inside the middle bone plate, and the middle bone plate is slidably connected to the first side bone plate. One end of the second side bone plate is embedded inside the middle bone plate, and the middle bone plate is slidably connected to the second side bone plate. In this technical solution, both the first and second side bone plates can slide relative to the middle bone plate. The overall size of the metal bone plate body can be adjusted by sliding the first and second side bone plates. After adjustment, the fastening plate is used to fasten the plate. This allows for rapid adjustment of the size of the metal bone plate body while ensuring the integrity and structural stability of the adjusted metal bone plate body. This improves the flexibility of the metal bone plate body during use, making it suitable for the needs of different patients.

[0004] However, in actual operation, it was found that after the metal bone plate body was adjusted and lengthened, that is, the two bone plates on both sides slid and adjusted in a direction away from each other relative to the middle bone plate, the ribs in the area directly opposite the middle bone plate and the two bone plates lacked the contact support of the bone plates, thus affecting the compression and fixation effect on the ribs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-5 This utility model provides the following two technical solutions:

[0029] First embodiment: An adjustable-size bone plate for orthopedics, comprising bone plate one 1 and bone plate two 2;

[0030] Both bone plate 1 and bone plate 2 have fixing holes for fixing to the ribs with screws.

[0031] Both bone plate 1 and bone plate 2 are L-shaped structures, and bone plate 1 and bone plate 2 are in contact with each other. This allows any area of ​​the rib to be supported by bone plate 1 or bone plate 2 when bone plate 1 and bone plate 2 move away from each other along the rib direction, thus solving the problems existing in the prior art.

[0032] In order to make the distance between bone plate 1 and bone plate 2 adjustable, a groove 3 is provided on the front side of bone plate 1, and screw holes 4 are evenly and laterally opened in the groove 3.

[0033] Among them, the second bone plate 2 is provided with a connecting block 5 located in the groove 3, and the connecting block 5 is provided with a screw 6 connected to one of the screw holes 4.

[0034] The right end of the groove 3 passes through the right end of the bone plate 1, so as not to affect the insertion of the bone plate 2 on the right side. The connecting block 5 enters through the opening at the right end of the groove 3.

[0035] Both sides of the connecting block 5 are provided with a stop bar 7 located in the groove 3, and the rear side of the stop bar 7 is in contact with the groove 3. The stop bar 7 is located on the front side of the screw hole 4. In this way, when adjusting the size, the connecting block 5 can move the stop bar 7 to cover the screw hole 4, thereby preventing dirt from entering the screw hole 4 and making subsequent cleaning easier.

[0036] In order to guide the sliding between the second bone plate 2 and the first bone plate 1, an inverted T-shaped slide bar 8 is provided on the second bone plate 2.

[0037] The bone plate 1 has an inverted T-shaped groove 9, and the slide rod 8 is slidably connected to the groove 9. The inverted T-shaped structure prevents the bone plate 1 and bone plate 2 from separating during sliding, and also facilitates the connection of screw 6 and corresponding screw hole 4. Screw 2 12 is provided on the groove 9. In order to allow the slide rod 8 to enter the groove 9, both ends of the groove 9 are open.

[0038] The second implementation differs from the first in that: because the inside of the sliding groove 9 has an inverted T-shaped structure, it is quite laborious to directly machine this structure into the bone plate 1. Since the sliding rod 8 is located on the outside of the bone plate 2, its machining is largely unimpeded. Therefore, a slot 10 and a mounting groove 11 are provided on the bone plate 1. The slot 10 and the mounting groove 11 are interconnected, and the mounting groove 11 is connected to the rear top of the slot 10. The rear-side connection provides a recess for the front side of the bone plate 1. In the space of 3, the slide groove 9 is inserted into the slot 10 and the mounting groove 11. The mounting groove 11 is provided with a screw hole 2, and the screw 2 12 is connected to the screw hole 2 to fix the slide groove 9. The left end of the groove 3 extends to the left side of the slot 10 and the mounting groove 11, so that the left stop bar 7 can be stored. It is easier to open the slot 10 and the mounting groove 11 on the bone plate 1 than the slide groove 9. Therefore, after opening, the pre-made slide groove 9 can be directly inserted into the slot 10 and the mounting groove 11, and finally fixed by the screw 2 12.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] In use, bone plate 1 and bone plate 2 are guided by sliding rod 8 and sliding groove 9, and then connected to screw holes 4 at different positions by screw 6, so that the size of bone plate 1 and bone plate 2 can be adjusted. After adjustment, the area of ​​the rib can be supported by bone plate 1 or bone plate 2, so as to ensure the compression and fixation effect of the rib while adjusting the size.
