Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a bone compression device. Background Technology

[0002] Bone compression therapy is a treatment method that uses an external fixator to apply pressure to the fracture ends to promote fracture healing. It is an intervention that uses an external fixator to apply pressure to the fracture ends to reduce gaps and stimulate bone growth. This technique aims to improve blood supply to the fracture site, thereby promoting bone healing.

[0003] Most traditional bone compressors on the market can only compress bones from the outside and do not have a prying function, making it difficult to meet the diverse needs of different bone repositioning. This may lead to doctors having to use less than ideal or less effective repositioning methods in certain situations. In addition, the lack of a precise adjustment mechanism makes it difficult for doctors to accurately position the device on the bone that needs to be repositioned, which may result in poor repositioning effect or even cause unnecessary damage to surrounding tissues. Therefore, a bone compressor is proposed to solve the above problems. Utility Model Content

[0026] Please see Figure 1-3 A bone compressor includes a fixation mechanism and a tilting mechanism, the tilting mechanism being disposed on the fixation mechanism.

[0027] In this embodiment, the fixing mechanism includes a fixing base 1, a fixing column 3 is fixedly installed at the front end of the top of the fixing base 1, a U-shaped frame 4 is fixedly installed at the top of the fixing column 3, and an opening 5 is provided at the rear end of the U-shaped frame 4.

[0028] It should be noted that the fixation base 1 serves as the supporting foundation for the entire bone compressor, and is fixedly installed on the operating table or in an appropriate position to ensure the stability of the bone compressor during the operation and provide a reliable installation platform for other components. The fixation column 3 connects the fixation base 1 and the U-shaped frame 4, playing a supporting and force-transferring role, so that the U-shaped frame 4 can be stably installed on the fixation base 1, ensuring the accuracy of the surgical operation. The U-shaped frame 4 provides an open space for doctors to observe and operate, and at the same time serves as a supporting structure for the tilting mechanism. The opening 5 is used to accommodate and adjust the threaded rod 9.

[0029] In this embodiment, the tilting mechanism includes support rods 6 fixedly installed at the left and right ends of the fixed base 1. Two sliders 7 are slidably connected to the surface of each support rod 6. A tightening nut 8 is threaded between the outer left wall of the slider 7 and the support rod 6.

[0030] It should be noted that the support rod 6 provides a sliding track for the slider 7, allowing the slider 7 to move freely on the support rod 6, thereby adjusting the position of the tilting head 2. The slider 7 is used to adjust the position of the connecting rod 13 and the tilting head 2. The tightening nut 8 is threaded between the slider 7 and the support rod 6 and is used to fix the position of the slider 7. By tightening or loosening the tightening nut 8, the position of the slider 7 can be locked or released to ensure the stability of the tilting head 2 during the operation.

[0031] In this embodiment, the left opening 5 of the U-shaped frame 4 is provided with a threaded hole, and a threaded rod 9 is threadedly connected inside the threaded hole, and the threaded rod 9 passes through the left opening 5 of the U-shaped frame 4.

[0032] It should be noted that the threaded rod 9 passes through the opening 5 of the spiral frame 4 and is used to fix the bone or surgical site. By rotating the handle 10, the position of the threaded rod 9 can be adjusted so that it fits tightly against the bone or surgical site to achieve a fixation effect.

[0033] In this embodiment, a handle 10 is fixedly installed at the end of the threaded rod 9 away from the spiral frame 4, and a stop block 11 is fixedly installed at the end of the threaded rod 9 away from the handle 10 and on the outer wall of the right end of the opening 5.

[0034] It should be noted that the handle 10 provides the doctor with a convenient rotation point, making the adjustment of the threaded rod 9 easier and more accurate. The stop block 11 is used to increase the contact area between the threaded rod 9 and the bone or surgical site, improving the fixation effect of the threaded rod 9 and preventing it from loosening or falling off during the operation.

[0035] In this embodiment, a limiting plate 12 is fixedly installed on the top of each of the two support rods 6, and a connecting rod 13 is rotatably connected to the outer wall of the rear end of each slider 7.

[0036] It should be noted that the limiting top plate 12 is used to limit the sliding range of the slider 7, preventing the slider 7 from exceeding the range of the support rod 6 during the sliding process, thus ensuring the safety of the surgical operation. The connecting rod 13 is used to transmit force and adjust the direction of the lifting head 2, so that the lifting head 2 can flexibly adjust its direction and angle as needed to adapt to the needs of different bone repositioning.

[0037] In this embodiment, each end of the connecting rod 13 away from the slider 7 is provided with a plug hole, and each plug hole is in which an installation rod 14 is inserted. At the ends of the installation rods 14 on the left and right sides that are close to each other, a pry bar 2 is fixedly installed. The head of the pry bar 2 is spike-shaped.

[0038] It should be noted that the mounting rod 14 is used to fix the lifting head 2, providing a stable mounting platform for the lifting head 2 and ensuring its stability and accuracy during the operation. The lifting head 2 is used to reposition the bone, and its spiked design can easily penetrate soft tissue and contact the bone to achieve a precise repositioning effect.

[0039] In summary, by setting up the fixed base 1, fixed column 3, U-shaped frame 4, and supporting rod 6, slider 7, tightening nut 8, mounting rod 14, and lifting head 2, precise lifting assistance for bone repositioning can be achieved. By adjusting the position of slider 7 on the supporting rod 6 and fixing it with the tightening nut 8, the position of lifting head 2 can be precisely adjusted to ensure that the lifting operation can accurately act on the bone part that needs to be repositioned, thereby improving the repositioning accuracy. Since slider 7 and connecting rod 13 are both designed to be rotatably connected, the direction and angle of lifting head 2 can also be flexibly adjusted as needed to adapt to the repositioning requirements of different bones, enhancing the flexibility of operation. The design of U-shaped frame 4 makes it easier for doctors to observe and operate, while the cooperation of threaded rod 9 and abutment block 11 provides a simple and effective fixation method, making the entire bone compressor more stable and reliable during operation, and facilitating the doctor's use.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
