Description

Technical Field

[0001] This utility model relates to the field of cross connector technology, specifically a medical adjustable cross connector. Background Technology

[0002] A medical transverse connector is an important passive implantable device. It is mainly used to connect and fix bones or soft tissues, especially in spinal surgery, to connect and fix vertebrae, straighten and fix the spine, and enable the vertebrae to connect and fuse with the implant.

[0003] Common cross connectors typically use crossbars for support, install nails via crossbar hooks, fix the position of the connecting shaft with locking screws, and adjust the length of the cross connector via the connecting shaft.

[0004] However, because the cross brace is a one-piece design, when it is necessary to fix other parts of the skeleton, only a matching cross beam can be used to fix the skeleton. Since the size of the skeleton is also different, the locking screw can only be fixed along the fixed direction, which means that the locking screw cannot effectively fix the skeleton. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a medical adjustable transverse connector to solve the problem mentioned in the background art, where the transverse connector is an integrated design. When it is necessary to fix other parts of the skeleton, only a matching transverse beam can be used to fix the skeleton. However, the size of the skeletons also varies, and the locking screws can only be fixed along the fixed direction, resulting in the locking screws not being able to effectively fix the skeleton.

[0028] 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.

[0029] This utility model provides a technical solution: a medical adjustable transverse connector. Please refer to [link / reference]. Figure 1 It includes a first horizontal connecting rod 1, and a second horizontal connecting rod 2 is provided on both sides of the first horizontal connecting rod 1;

[0030] Connecting bracket 3 is located at the outer end of the second horizontal connecting rod 2. Please refer to [link / reference]. Figure 5 The connecting frame 3 has a U-shaped design. A first screw 4 is installed on the upper surface of the base plate of the connecting frame 3. The upper part of the first screw 4 penetrates the top plate of the connecting frame 3. An adjusting block 5 is installed on the surface of the first screw 4. A first nut 6 is screwed onto the upper surface of the first screw 4.

[0031] Please see Figure 1 The third horizontal connecting rod 7 is disposed on the surface of the adjusting block 5. Adjusting seats 8 are provided on the surfaces of the first horizontal connecting rod 1, the second horizontal connecting rod 2, and the third horizontal connecting rod 7. Please refer to [link / reference]. Figure 3 The upper surface of the adjusting seat 8 is equipped with a first locking block 9, and the connecting surface of the first locking block 9 is provided with a second locking block 10. A limit bolt 11 is screwed between the first locking block 9 and the second locking block 10.

[0032] Adjustment bracket 12 is located below adjustment base 8. Please refer to [link / reference]. Figure 4 All surfaces of the adjusting frame 12 are screwed with locking screws 13, and all top plates of the adjusting frame 12 are inserted with second screws 14. The second screws 14 are all installed at the bottom of the adjusting seat 8, and all surfaces of the second screws 14 are screwed with second nuts 15.

[0033] Rotating the first nut 6 loosens the first screw 4, allowing the angle of the third cross link 7 to be adjusted via the adjusting block 5. The offset angle of the adjusting seats 8 on both sides can be adjusted via the third cross link 7. Rotating the limiting bolt 11 moves the second locking block 10, thereby moving the adjusting seat 8 and adjusting the position of the locking screw 13. Rotating the second nut 15 separates it from the adjusting frame 12, allowing the adjusting frame 12 to rotate around the second screw 14, further adjusting the orientation of the locking screw 13. This allows the cross link to be used for different parts of the skeleton, and by adjusting the position and orientation of the locking screw 13, the skeleton can be more effectively fixed.

[0034] Please see Figure 2 The first horizontal connecting rod 1 is hollow, and the second horizontal connecting rod 2 is inserted into the interior of the first horizontal connecting rod 1, so that the second horizontal connecting rod 2 can be extended, thereby increasing the range of motion of the adjusting seat 8.

[0035] Mounting holes 16 are evenly provided on the surfaces of the first horizontal connecting rod 1 and the second horizontal connecting rod 2. Mounting rods 17 are screwed into the interior of the mounting holes 16 that overlap between the first horizontal connecting rod 1 and the second horizontal connecting rod 2. The second horizontal connecting rod 2 can be connected to the first horizontal connecting rod 1 through the mounting rods 17.

[0036] Please see Figure 3Limiting blocks 18 are installed on the connecting surfaces of the second locking block 10. The limiting blocks 18 penetrate the surface of the first locking block 9. The limiting blocks 18 make it difficult for the second locking block 10 to detach from the first locking block 9 when it moves.

[0037] The surface of the adjusting seat 8 is provided with mounting grooves, and the mounting grooves of the adjusting seat 8 are all of the C-shaped design. The bottom of the second locking block 10 is embedded in the mounting groove of the adjusting seat 8, so that the second locking block 10 can move stably.

[0038] Please see Figure 5 The surface of the first screw 4 is fitted with a first locking washer 19. Please refer to [link / reference]. Figure 4 The surface of the second screw 14 is fitted with a second locking washer 20. The first locking washer 19 can improve the fastening effect of the first nut 6 on the first screw 4, and the second locking washer 20 can improve the fastening effect of the second nut 15 on the adjusting bracket 12.

[0039] The working process of this device is as follows: First, the second horizontal connecting rod 2 is pulled out from inside the first horizontal connecting rod 1, which increases the movement range of the adjusting seat 8. The second horizontal connecting rod 2 is connected to the first horizontal connecting rod 1 via the mounting rod 17. Then, rotating the first nut 6 loosens the first screw 4, allowing the angle of the third horizontal connecting rod 7 to be adjusted via the adjusting block 5. Rotating the first nut 6 again tightens the first screw 4, thus fixing the third horizontal connecting rod 7. The offset angle of the adjusting seats 8 on both sides can be adjusted via the third horizontal connecting rod 7. Rotating the limiting bolt 11 moves the second locking block 10, allowing the adjusting seat 8 to move and the locking screw 13 to be adjusted. The position is adjusted by rotating the limiting bolt 11 again, which causes the locking block to press against the horizontal connecting rod, thereby fixing the adjusting seat 8. Finally, rotating the second nut 15 separates it from the adjusting frame 12, allowing the adjusting frame 12 to rotate around the second screw 14 as the axis, thereby further adjusting the orientation of the locking screw 13. After the locking screw 13 is adjusted, rotating the second nut 15 presses against the adjusting frame 12, causing the adjusting frame 12 to fit tightly against the bottom of the adjusting seat 8, thus fixing the adjusting frame 12. This allows the horizontal connector to be used for different parts of the skeleton, and by adjusting the position and orientation of the locking screw 13, the skeleton can be fixed more effectively.
