Description

Technical Field

[0001] The utility model relates to a highly stable spinal correction internal fixation structure, belonging to the technical field of medical instruments. Background Technique

[0002] Spinal correction, the abbreviation of spinal correction technology, refers to a technology dedicated to resetting displaced and subluxated vertebrae and adjusting spinal joints. It is similar to the pulling and bone-setting techniques in traditional Chinese medicine, but has its own systematic theoretical guidance and unique force application skills. It is a scientific and efficient treatment technology.

[0003] A spinal posterior internal fixation connecting rod with Chinese patent number CN211633534U includes a main rod body. An angular parallel axis is arranged on the outer surface of the upper end of the main rod body. A rod cap is arranged on the outer surface of the angular parallel axis. A fastening screw is arranged inside the rod cap, which can better adapt to different angle requirements during installation and can better improve the anti-slip effect during installation. Coupled with the different diameters of each anti-slip ring, it can better cooperate with auxiliary devices of different models, making the actual installation more convenient and bringing a better application prospect.

[0004] After the operation, it is not convenient to apply medicine to the opening position of the patient's spinal lesion, resulting in room for improvement in the recovery process after the treatment of the patient's spinal lesion. Therefore, it is necessary to design a highly stable spinal correction internal fixation structure with stronger functionality to solve the above problems.

[0005] For this reason, a highly stable spinal correction internal fixation structure is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides a highly stable spinal correction internal fixation structure to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: A highly stable spinal correction internal fixation structure includes a strip-shaped cross bar. A pair of fixed column heads are arranged outside the strip-shaped cross bar in a matching manner. A middle opening is arranged at the inner end of the fixed column head. The strip-shaped cross bar penetrates inside and outside the middle opening. A medicine storage layer is arranged at the front end of the fixed column head. The medicine storage layer includes a water-soluble mesh bag. A number of medicine powders are filled at the inner end of the water-soluble mesh bag. The medicine storage layer includes an outer attached isolation surface. A paste layer is fixedly connected to the outer end of the outer attached isolation surface. The outer attached isolation surface is located outside the water-soluble mesh bag.

[0008] Further preferably, the paste layer is adhesively connected to the outer wall surface of the fixed column head, and a raised easy-to-tear strip is fixedly connected to the upper end of the paste layer.

[0009] Further preferably, a gap layer is formed between the raised easy-to-tear strip and the medicine storage layer, and a screw column is fixedly connected to the lower end of the fixed column head.

[0010] Further preferably, several threads are provided outside the screw column, and a nut block is fixedly connected to the upper end of the fixed column head.

[0011] Further preferably, a screw hole is provided at the upper end of the nut block, and a pair of silica gel clamping rings are provided at the upper end of the strip-shaped cross bar.

[0012] Further preferably, the silica gel clamping ring is clamped outside the strip-shaped cross bar, and an inwardly concave micro-ring is provided at the upper end of the silica gel clamping ring.

[0013] Further preferably, a medical pushing forceps is externally connected to the inwardly concave micro-ring, and the screw column penetrates through the affected area of the patient's spine.

[0014] Due to the adoption of the above technical solutions in the embodiments of the present utility model, it has the following advantages:

[0015] 1. When the screw column is installed at the affected area in this solution, a medicine storage layer can be fixedly connected outside the fixed column head. The medicine storage layer mainly fills the medicine powder into the water-soluble mesh bag and limits the diffusion range of the water-soluble mesh bag through the externally attached isolation surface. Before the doctor finishes installing all the screw columns and needs to suture the wound, the adhesive layer outside the externally attached isolation surface is torn off, and then the suture operation is carried out. At this time, the medicine powder in the water-soluble mesh bag can gradually contact and hydrolyze and melt with substances such as the mucosal water fluid at the affected area, so that the medicine powder gradually spreads around the affected area of the screw column, making the recovery process after treatment better, facilitating ensuring the wound healing efficiency, and improving the functionality during the use of the medicine storage layer.

[0016] 2. At the same time, when the externally attached isolation surface is removed from outside the water-soluble mesh bag, a raised easy-to-tear strip can be provided on the adhesive layer. A gap can be generated between the raised easy-to-tear strip and the outer wall surface of the fixed column head, enabling the staff to quickly and conveniently remove the entire externally attached isolation surface using forceps. At the same time, multiple silica gel clamping rings can be added outside the strip-shaped cross bar. The silica gel clamping rings are clamped outside the strip-shaped cross bar, which can generate a cushion layer between the strip-shaped cross bar and the medical pushing forceps, enabling the medical pushing forceps to be accurately connected and clamped with the strip-shaped cross bar, making the displacement operation of the screw column more stable and not prone to random sliding.

[0017] The above summary is only for the purpose of the specification and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present utility model will be readily apparent by reference to the drawings and the following detailed description.

The outer pasted isolation surface 7 is located outside the water-soluble net bag 10.

[0028] The lower end of the fixed column head 1 is fixedly connected with a screw column 3. A number of threads are provided on the outside of the screw column 3. The upper end of the fixed column head 1 is fixedly connected with a nut block 5. A screw hole is provided at the upper end of the nut block 5. The screw column 3 penetrates through the affected area of the patient's spine.

[0029] Embodiment 2

[0030] In one embodiment, it is adhesively connected between the outer wall surface of the paste layer 8 and the fixed column head 1. The upper end of the paste layer 8 is fixedly connected with a convex easy-to-tear strip 9. A gap layer is formed between the convex easy-to-tear strip 9 and the medicine storage layer 6.

[0031] A pair of silicone snap rings 12 are provided at the upper end of the strip-shaped cross bar 4. The silicone snap rings 12 are snapped outside the strip-shaped cross bar 4. An inward concave micro-ring 13 is provided at the upper end of the silicone snap rings 12. The inward concave micro-ring 13 is externally connected with a medical pushing forceps.

[0032] When the present utility model is working: In this solution, the screw column 3 is arranged outside the strip-shaped cross bar 4 and the screw column 3 penetrates through the affected area of the patient's spine. The cooperation between the screw column 3 and the strip-shaped cross bar 4 is utilized to complete the spinal correction operation. When the screw column 3 is installed at the affected area, the medicine storage layer 6 can be fixedly connected outside the fixed column head 1. The medicine storage layer 6 mainly fills the medicine powder 11 into the water-soluble mesh bag 10, and the diffusion range of the water-soluble mesh bag 10 is restricted by the outer sticker isolation surface 7. Before the doctor finishes installing all the screw columns 3 and needs to perform wound suture, the paste layer 8 outside the outer sticker isolation surface 7 is torn off, and then the suture operation is carried out. At this time, the medicine powder 11 in the water-soluble mesh bag 10 can gradually contact and hydrolyze and melt with substances such as the mucosal water fluid at the affected area, so that the medicine powder 11 gradually spreads around the affected area of the screw column 3, making the recovery process after treatment better, facilitating the guarantee of the wound healing efficiency, improving the functionality of the medicine storage layer 6 during use. At the same time, when the outer sticker isolation surface 7 is removed from the outside of the water-soluble mesh bag 10, the convex easy-to-tear strip 9 can be provided on the paste layer 8. A gap can be formed between the convex easy-to-tear strip 9 and the outer wall surface of the fixed column head 1, enabling the staff to quickly and conveniently remove the entire outer sticker isolation surface 7 by using tweezers. At the same time, a plurality of silicone snap rings 12 can be additionally provided outside the strip-shaped cross bar 4. The silicone snap rings 12 are snapped outside the strip-shaped cross bar 4, which can generate a cushion layer between the strip-shaped cross bar 4 and the medical pushing forceps, enabling the medical pushing forceps to be accurately connected and snapped with the strip-shaped cross bar 4, making the displacement operation of the screw column 3 more stable and not prone to random sliding.

[0033] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto.
