Description

Technical Field

[0001] The utility model relates to the technical field of surgical instrument kits, and more specifically, to an adjustable surgical instrument kit for cervical spinal fusion cages. Background Art

[0002] Cervical spinal fusion surgery is a very common surgical method and is currently the standard surgical method for treating various cervical spondylosis in clinical practice. Intervertebral fusion surgery is mainly due to vertebral slippage in patients. In order to stabilize two adjacent vertebrae, a CAGE can be placed between the vertebrae or bone grafting can be performed to fuse the two vertebrae together, which can stabilize the patient's spine, prevent further sliding of the spine, and relieve the patient's symptoms. Generally, it is mainly applied to patients with slippage, such as cervical spondylolisthesis and lumbar spondylolisthesis. When performing cervical spine surgery, an instrument kit for accommodating surgical instruments is required.

[0003] However, the traditional surgical instrument kit has a fixed size. The surgical instruments are directly placed in the kit, and the number of instruments placed is limited by the size of the kit. It is inconvenient to adjust the storage space of the surgical instrument kit according to actual needs, so as to change the storage capacity. Therefore, an adjustable surgical instrument kit for cervical spinal fusion cages is proposed. Summary of the Utility Model

[0024] As shown in the attached Figures 1-5 Shown adjustable cervical fusion surgical instrument kit, including a take-up reel 1, a rotating shaft 2 is arranged in the middle of the take-up reel 1, one end of the rotating shaft 2 penetrates through the wall of the take-up reel 1 and is fixedly connected with a turntable 3, by rotating the turntable 3, the rotation of the rotating shaft 2 inside the take-up reel 1 can be controlled, and the other end penetrates through the wall of the take-up reel 1 and is fixedly connected with a limiting plate 4, the positions of the rotating shaft 2 and the turntable 3 are limited by the limiting plate 4 to avoid sliding and affecting the use effect. An adjustment and locking mechanism is arranged on one side of the take-up reel 1, which can fix the rotation angle and the number of turns of the rotating shaft 2, so as to adjust the length of the two cloth bags 5, so as to realize the adjustment of the number of stored instruments and facilitate the adjustment and use;

[0025] A strip hole 10 is opened on one side of the take-up reel 1, two cloth bags 5 are wound around the middle of the rotating shaft 2, a pull chain 6 is arranged on the edge of the cloth bag 5, a plurality of elastic bands 7 are arranged on the opposite side of the two cloth bags 5, a handbag 9 is fixedly connected to the opposite side of the two cloth bags 5, zipper heads 8 are symmetrically arranged on both sides of the pull chain 6. Through the strip hole 10, one end of the cloth bag 5 wound around the middle of the take-up reel 1 can be taken out from the inside of the take-up reel 1, and pulled up through the zipper head 8 until the two zipper heads 8 coincide, so that the two cloth bags 5 can form the form of a handbag, and the instruments for cervical fusion surgery can be conveniently limited and fixed on one side of the cloth bag 5 through the elastic bands 7, which is convenient for carrying, and is convenient for carrying by hand through the handbag 9.

[0026] As shown in the attachment Figures 1-3 As shown, the zipper chain 6 is adapted to the zipper head 8. One end of the cloth bag 5 passes through the middle of the strip hole 10 and extends to the outside. Two zipper heads 8 are arranged on both sides of the winding drum 1 close to the strip hole 10. Through the cooperation of the zipper chain 6 and the zipper head 8, the edge of the cloth bag 5 can be controlled to fit or not by moving the zipper head 8, which is convenient for opening and closing.

[0027] As shown in the attachment Figures 2-5 As shown, the adjusting and locking mechanism includes a positioning plug 11 fixed on one side of the limiting plate 4. A limiting ring 12 is fixedly connected to one side of the winding drum 1 close to the limiting plate 4. A sleeve 14 is sleeved in the middle of the limiting ring 12. One end of the sleeve 14 is fixedly connected to a pulling plate 15. By fixing the positioning plug 11, the rotation shaft 2 can be fixed, and the sleeve 14 is sleeved in the middle of the limiting ring 12 to improve the moving stability of the sleeve 14 and the pulling plate 15.

[0028] As shown in the attachment Figures 2-5 As shown, the diameter of the pulling plate 15 is larger than that of the sleeve 14, the diameter of the sleeve 14 is the same as that of the winding drum 1, and a fixing block 18 is fixedly connected to one side of the pulling plate 15. A positioning slot 19 is opened on one side of the fixing block 18. The positioning slot 19 is adapted to the positioning plug 11, which is convenient for pulling the pulling plate 15 to separate the positioning slot 19 from the positioning plug 11.

[0029] As shown in the attachment Figures 2-5 As shown, the cross-sectional shape of the positioning plug 11 is set as a square, and one end of the positioning plug 11 extends into the positioning slot 19. By inserting the positioning plug 11 into the positioning slot 19, the rotation shaft 2 can be limited by the pulling plate 15. When the pulling plate 15 is fixed, the rotation shaft 2 is fixed to prevent the rotation shaft 2 from accidentally rotating and affecting the storage and use effect.

[0030] As shown in the attachment Figures 2-5 As shown, a limiting chute 13 is opened on the outer surface of the limiting ring 12. A limiting block 16 is fixedly connected to the middle of the sleeve 14. The limiting block 16 is adapted to the limiting chute 13. Through the cooperation of the limiting chute 13 and the limiting block 16, the sleeve 14 can be limited to prevent the sleeve 14 from rotating. At the same time, the sleeve 14 can drive the limiting block 16 to move horizontally, and the limiting block 16 moves in the limiting chute 13.

[0031] As shown in the attachment Figures 2-5 As shown, a spring 17 is arranged on one side of the limiting block 16. The limiting block 16 and the spring 17 are both arranged in the middle of the limiting chute 13. The spring 17 is arranged on the side of the limiting block 16 away from the winding drum 1. When the limiting block 16 moves in the limiting chute 13, the spring 17 will be compressed, generating a reset force for the pulling plate 15, which is convenient for use.

[0032] Working principle of the utility model: When in use, just place the instrument for cervical spine fusion surgery in the middle of the elastic band 7. The elastic band 7 limits the instrument. By pulling the cooperation of the zipper head 8 and the zipper chain 6, the opening and closing between the two cloth bags 5 can be realized, which is convenient for use and storage. The handbag 9 is convenient for carrying by hand.

[0033] When the storage quantity needs to be adjusted, the positioning slot 19 can be separated from the positioning plug 11 by pulling the pull plate 15. At this time, the limiting block 16 squeezes the spring 17, and then the turntable 3 is rotated to control the rotation of the rotating shaft 2, or the cloth bag 5 can be directly pulled to draw out the cloth bag 5 from the middle of the winding drum 1, so as to adjust the length of the cloth bag 5, and thus adjust the storage quantity.

[0034] By releasing the pull plate 15, the spring 17 pushes the limiting block 16, and the positioning plug 11 automatically inserts into the inside of the positioning slot 19, so that the rotating shaft 2 can be fixed, thereby realizing the fixing of the extended length of the pull plate 15, which is convenient for adjustment and use.

[0035] The above are only the preferred embodiments of the utility model and are not used to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
