Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an adjustable spinal cord protection device. Background Art

[0002] In clinical practice, the spinal canal needs to be expanded and decompressed. A full or half laminectomy is routinely performed. After removing the spinous processes and lamina of the posterior column and other bony protective structures, the spinal cord is completely exposed. When the surgeon performs fusion or internal fixation implantation and other operations, the spinal cord may be easily damaged if the operation is not careful. Therefore, protective devices are needed to protect it.

[0028] An adjustable spinal cord protection device comprises a No. 1 support rod 1 and a No. 2 support rod 2 arranged above the No. 1 support rod 1. There are two No. 1 support rods 1. The outer sides of the two No. 1 support rods 1 are sleeved with a No. 1 sliding ring 3. The inner side of the No. 1 sliding ring 3 is rotatably sleeved with a No. 2 sliding ring 301. An adjusting rod 302 is fixedly installed on the outer side of the No. 2 sliding ring 301. A clamping hole 303 is opened on the outer surface of the adjusting rod 302. Connecting rods 4 are fixedly installed on the opposite ends of the No. 1 sliding ring 3. An adjusting cylinder 401 is sleeved between the connecting rods 4. The No. 1 support rod 1 is sleeved with a No. 1 sliding ring 301. The front end of the second support rod 1 is respectively provided with a limit column 5 and a third support rod 6, the outer side of the second support rod 2 is movably sleeved with a third sliding ring 7, the outer surface of the third sliding ring 7 is provided with a fixed sleeve rod 701, the bottom end surface of the fixed sleeve rod 701 is provided with an adjustment groove 702, the rear side of the fixed sleeve rod 701 is fixedly installed with a mounting seat 703, the interior of the mounting seat 703 is respectively provided with a support compression spring 704 and a clamping column 705, the front end of the second support rod 2 is provided with an adjustment stud 8 and a fourth support rod 9, and the rear end surface of the fourth support rod 9 is provided with an adjustment hole 10;

[0029] It should be noted that the shapes and sizes of the No. 1 support rod 1 , the No. 2 support rod 2 , the No. 3 support rod 6 and the No. 4 support rod 9 are consistent, and the inner side of the No. 1 sliding ring 3 is slidably matched with the outer surface of the No. 1 support rod 1 .

[0030] Specifically, the inner wall of the adjusting cylinder 401 is provided with a bidirectional internal thread, the cross-sectional shape of the connecting rod 4 is an I-shaped structure, and the outer end surfaces thereof facing each other are provided with external threads matching the bidirectional internal thread;

[0031] In this embodiment, the setting of the adjustment cylinder 401 is mainly used for threaded transmission with the connecting rod 4. Under the setting of the two-way internal thread, the connecting rods 4 can move toward or away from each other, thereby achieving the effect of adjusting the distance between the No. 1 support rods 1.

[0032] Specifically, the inner wall of the adjustment groove 702 is in sliding contact with the outer surface of the adjustment rod 302, the clamping column 705 is fixed to the front end of the support compression spring 704 through a limiting ring, and its front end extends through the inside of the adjustment groove 702 and is plugged into the clamping hole 303, and the rear end of the clamping column 705 extends to the rear end of the mounting seat 703;

[0033] In this embodiment, the setting of the adjustment groove 702 is mainly used to achieve telescopic movement with the adjustment rod 302. Under the action of the support compression spring 704, it elastically supports the clamping column 705, so that the clamping column 705 and the clamping hole 303 are plugged in, ensuring the fixing effect between the fixed sleeve rod 701 and the adjustment rod 302, thereby achieving the effect of adjusting the distance between the No. 1 support rod 1 and the No. 2 support rod 2.

[0034] Specifically, a limiting hole 601 is provided on the rear surface of the third support rod 6, the inner wall of the limiting hole 601 is in close contact with the outer surface of the limiting column 5, and the inner wall of the adjustment hole 10 is provided with an internal thread matching the adjustment stud 8;

[0035] In the present embodiment, the fitting arrangement of the limit hole 601 and the limit column 5 is mainly for facilitating the horizontal movement between the No. 3 support rod 6 and the No. 1 support rod 1, and the arrangement of the adjusting stud 8 is mainly used to form a threaded engagement with the adjusting hole 10, thereby achieving the effect of adjusting the horizontal distance between the No. 2 support rod 2 and the No. 4 support rod 9, thereby meeting the adjustment needs of medical staff.

[0036] The working process of the utility model is as follows: when using an adjustable spinal cord protection device, when the length of the device needs to be adjusted, hold the No. 2 support rod 2 and the No. 4 support rod 9 and apply an external force to the No. 2 support rod 2. Driven by the external force, the No. 2 support rod 2 drives the adjusting stud 8 to rotate, and then the adjusting stud 8 gradually separates from the adjusting hole 10. At this time, the distance between the No. 4 support rod 9 and the No. 2 support rod 2 gradually increases, thereby completing the length adjustment of the device. When the width of the device needs to be adjusted, an external force is applied to the adjusting cylinder 401 to rotate it, and then the connecting rods 4 are back to back. Movement, at this time the distance between the No. 1 support rod 1 changes accordingly, thereby completing the width adjustment of the device, and when the height of the device needs to be adjusted, the distance adjustment between the No. 1 support rod 1 and the No. 2 support rod 2 is achieved under the sliding cooperation between the adjustment slot 702 and the adjustment rod 302, and under the elastic support of the support compression spring 704, it drives the clamping column 705 and fits with the clamping hole 303, ensuring the stability between the fixed sleeve rod 701 and the adjustment rod 302, thereby completing the height adjustment of the device, thus meeting the adjustment needs of medical staff, facilitating the protection of the patient's spinal cord, and improving the practical effect of the device.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
