Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a visual endplate scraper with support and fixation functions. Background Art

[0002] In spinal surgery, the treatment of the intervertebral disc cartilage endplate is one of the key steps for the success of intervertebral fusion surgery. Appropriate and sufficient treatment of the intervertebral disc cartilage endplate is crucial for ensuring postoperative intervertebral fusion. Currently, due to the deep anatomical location of the intervertebral space and limited operating vision, orthopedic surgeons at home and abroad generally rely on "hand feeling" and "experience" when using endplate scrapers to treat the intervertebral disc cartilage endplate, and this operation cannot be performed under direct vision. High-quality endplate treatment can provide a better bone contact surface for bone graft materials or intervertebral fusion cages, promoting bone healing and fusion.

[0003] However, in actual surgical operations, traditional endplate scrapers are usually used for endplate cleaning. These tools have the following limitations: Firstly, the scraping direction of the scraper is fixed and the operation is not flexible; Secondly, currently clinicians mainly rely on "hand feeling" and "experience", and this operation cannot be performed under direct vision; Finally, in a narrow surgical field or minimally invasive surgical conditions, it may affect the accuracy and efficiency of cleaning. Therefore, based on the above problems, the present invention provides a visual endplate scraper with support and fixation functions to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a visual endplate scraper with support and fixation functions. By setting a support component and a cleaning component, the support component can not only achieve the expansion and fixation of the narrow space in the intervertebral space, but also perform support and fixation according to the elastic deformation of the support component itself, thereby making it more convenient for the scraper to treat the intervertebral disc cartilage endplate; the cleaning component can not only clean the intervertebral disc cartilage endplate, but also cooperate with the support component to achieve multi-degree-of-freedom direction transformation of the scraper. In addition, with the cooperation of a high-definition camera, the visualization of the narrow space at the diseased intervertebral space is realized, improving the accuracy and efficiency of cleaning, and greatly increasing the success rate of the surgery. Through the above settings, the problems of limitations existing when traditional endplate scrapers are used for endplate cleaning can be solved.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A visual endplate scraper with support and fixation functions, including a tool body, one end of the tool body is fixedly connected with a cleaning component for treating the intervertebral disc cartilage endplate, and the cleaning component is connected to the tool body; a support component for assisting in the support and fixation of the intervertebral space, and the support component is connected to the tool body.

[0007] Optionally, the support component includes steel sheets symmetrically inserted inside the blade body, a high-definition camera is inserted between the steel sheets, a fixing block is fixedly installed on one side of the steel sheet close to the inner wall of the blade body, arc-shaped grooves are formed in the inner wall of the blade body in a linear array distribution, elastic sheets distributed oppositely are fixedly connected to the arc-shaped grooves, and the inner wall size of the elastic sheet is adapted to the outer wall size of the fixing block.

[0008] Optionally, a handle is fixedly connected to the top of the blade body, a circular groove communicating with the inner wall of the blade body is formed at the center of the handle, and limiting grooves are formed on both sides of the handle.

[0009] Optionally, support grooves are symmetrically formed at positions close to the bottom of the blade body, and the inner wall size of the support groove is larger than the outer contour size of the steel sheet.

[0010] Optionally, the steel sheet is a curved surface elastic structure, both sides of the steel sheet are arc-shaped structures bent towards the inside, the outer contour size of the steel sheet is smaller than the inner wall size of the blade body, and the position of the steel sheet corresponding to the support groove has an arc-shaped bending angle.

[0011] Optionally, the top of the steel sheet penetrates through the circular groove, a bent portion is arranged at the top of the steel sheet, a flanging portion is arranged at the bottom of the bent portion, and the inner wall size of the limiting groove is larger than the outer contour size of the flanging portion.

[0012] Optionally, the elastic sheet is a curved surface elastic structure, the cross section of the elastic sheet is a "human"-shaped structure, and one side of the elastic sheet is fixedly connected to the arc-shaped groove on the inner wall of the blade body.

[0013] Optionally, the cleaning component includes an upper rotating part fixedly connected to the bottom of the blade body, a lower rotating part is rotatably connected to the bottom of the upper rotating part, a scraping head is fixedly connected to the bottom of the lower rotating part, a hollow groove is formed at the center of the scraping head, and the bottom of the high-definition camera extends into the hollow groove.

[0014] Optionally, the top of the scraping head communicates with the inner wall of the blade body, a circumferentially arrayed hook is fixedly connected to the top of the scraping head, the hook is an elastic structure, and the circular contour size formed by the bottom of the hook is smaller than the outer contour size of the high-definition camera.

[0015] Optionally, obliquely protruding portions are symmetrically arranged at the bottom of the scraping head.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting a support component and a cleaning component, the support component and the cleaning component are respectively arranged inside and at the bottom of the knife body. The support component can not only realize the expansion and fixation of the narrow space of the intervertebral disc, but also can support and fix according to the elastic deformation of the support component itself, so as to make it more convenient for the scraper to process the cartilage endplate of the intervertebral disc; the cleaning component can not only clean the cartilage endplate of the intervertebral disc, but also can cooperate with the support component to realize the multi-degree-of-freedom direction change of the scraper. In addition, in combination with a high-definition camera, the narrow space at the diseased intervertebral disc is visualized, the accuracy and efficiency of cleaning are improved, and the success rate of the operation is greatly improved.

[0018] By setting the support groove and the steel sheet, there are two states between the support groove and the steel sheet: when the blade needs to be inserted into the intervertebral space, the steel sheet is in a straightened state, which is convenient for inserting the scraper to the end plate; when the scraper head reaches the end plate, the steel sheet is released, and the steel sheet relies on its own elasticity to restore to an arc-shaped angle at the position corresponding to the support groove, and the fixing block cooperates with the spring sheets at different positions to achieve support and fixation of the steel sheet; during actual operation, medical personnel can use the above two states to expand and fix the intervertebral space, and this fixing method is not only simple in structure but also easy to operate.

[0019] By setting the fixed block and the spring sheet in coordination, the spring sheet is adapted to the shape contour of the fixed block, and the top of the steel sheet is pinched by hand, and the top of the steel sheet is elastically deformed, so that the fixed block is separated from the oppositely distributed spring sheet. When the hand is released, the steel sheet rebounds to contact the spring sheet, and the steel sheet squeezes the spring sheet inward. The fixed block is fixed by utilizing the structural coordination of the spring sheet and the fixed block. The spring sheet can not only fix the fixed block at different heights to form different degrees of support and fixation, but also the spring sheet is arranged in a whole circle. When the angle of the scraper head is adjusted by the fixed block, it can be freely rotated and fixed within the range allowed by the support groove to meet the multi-degree-of-freedom direction change of the scraper.

[0020] By setting up a high-definition camera and a hook to cooperate, the high-definition camera extends to the free end of the hook and continues downward, and the elastic structure of the hook is used to cooperate with the outer contour of the high-definition camera. When the high-definition camera extends to the inside of the hollow groove, the free end of the hook is stretched open to clamp the high-definition camera. The setting of the hook is not only simple and clever in structure, but also convenient and labor-saving in actual operation. In addition, the hook and the scraper head are an integrated manufacturing structure. Such a setting makes the processing technology of the two simpler during the production process, easier to produce, and reduces the manufacturer's capital investment.

[0021] By setting the bending part, the flanging part and the limiting groove cooperate. There are two states for the bending part and the flanging part: when the steel sheet is straightened, the bending part is unfolded, and at this time the flanging part is received inside the limiting groove for fixation, which is convenient for the scraper to be inserted into the vertebral space. When the position of the steel sheet corresponding to the support groove is extruded into an arc protruding from the outer wall of the scraper, the flanging part and the bending part return to the bent state. The structure of the bending part not only facilitates the medical staff to pinch the steel sheet for adjustment, but also the outer contour of the bending part is larger than the inner wall size of the circular groove, ensuring that the steel sheet will not slide into the inside of the tool body, thus ensuring the smooth progress of the operation.

[0040] As Figures 1 to 9 shown, an embodiment of the present invention provides a visual endplate scraper having support and fixation functions, including a tool body 1. One end of the tool body 1 is fixedly connected with a cleaning assembly for processing the intervertebral disc cartilage endplate, and the cleaning assembly is connected to the tool body 1; a support assembly for assisting in the support and fixation of the intervertebral disc space, and the support assembly is connected to the tool body 1. The visual endplate scraper with support and fixation functions provided in this application is used for processing the intervertebral disc cartilage endplate in lumbar interbody fusion surgery. Intervertebral disc fusion surgery is to fuse the two vertebrae above and below the diseased intervertebral disc. The treatment method is to implant a fusion device made of metal or other implantable materials into the diseased intervertebral disc space to support the upper and lower vertebrae, and then perform bone grafting, and finally fuse the upper and lower two vertebrae. The working principle of intervertebral disc fusion surgery is publicly known in the prior art and will not be elaborated herein.

[0041] Among them, as Figures 4 to 9As shown, the support assembly includes steel sheets 5 symmetrically inserted inside the tool body 1. A high-definition camera 6 is inserted between the steel sheets 5. A fixing block 15 is fixedly installed on one side of the steel sheet 5 close to the inner wall of the tool body 1. Arc-shaped grooves 13 distributed in a linear array are formed on the inner wall of the tool body 1. Oppositely distributed elastic pieces 14 are fixedly connected to the arc-shaped grooves 13. The inner wall size of the elastic piece 14 is adapted to the outer wall size of the fixing block 15. By using the cooperation between the fixing block 15 and the elastic piece 14, the position and angle of the steel sheet 5 are locked. The arc-shaped grooves 13 are formed in a full circle on the inner wall of the tool body 1 and are fixedly connected to the elastic pieces 14 arranged in a full circle to ensure the fixation of the fixing block 15, thereby limiting the steel sheet 5. By installing a high-definition camera 6 inside the tool body 1 and then through an external visualization window, the visualization of the surgical field is realized, making the surgery more accurate and safe, and improving the success rate of the surgery. The working principle of the visual medical surgery is publicly available as prior art and will not be elaborated here.

[0042] By providing a support assembly and a cleaning assembly, the support assembly and the cleaning assembly are respectively arranged inside and at the bottom of the tool body 1. The support assembly can not only realize the expansion and fixation of the narrow space of the intervertebral space, but also perform support fixation according to the elastic deformation of the support assembly itself, thus making it more convenient for the scraping tool to process the cartilage endplate of the intervertebral space; the cleaning assembly can not only clean the cartilage endplate of the intervertebral space, but also cooperate with the support assembly to realize the multi-degree-of-freedom direction transformation of the scraping tool. In addition, combined with the high-definition camera 6, the visualization of the narrow space at the diseased intervertebral space is realized, improving the accuracy and efficiency of cleaning, and greatly improving the success rate of the surgery.

[0043] In this embodiment, as Figures 1 to 4 and Figures 7 to 8As shown in the figure, a handle 2 is fixedly connected to the top of the tool body 1. A circular groove 16 communicating with the inner wall of the tool body 1 is provided at the center of the handle 2. Limiting grooves 12 are provided on both sides of the handle 2. The top of the steel sheet 5 penetrates through the circular groove 16. A bending part 10 is provided at the top of the steel sheet 5. A flanging part 11 is provided at the bottom of the bending part 10. The inner wall size of the limiting groove 12 is larger than the outer contour size of the flanging part 11. Support grooves 4 are symmetrically provided at a position near the bottom of the tool body 1. The inner wall size of the support groove 4 is larger than the outer contour size of the steel sheet 5. The steel sheet 5 is a curved elastic structure. Both sides of the steel sheet 5 are arc-shaped structures bent towards the inside. The outer contour size of the steel sheet 5 is smaller than the inner wall size of the tool body 1. The position of the steel sheet 5 corresponding to the support groove 4 has an arc-shaped bending angle. By using the cooperation between the steel sheet 5 and the support groove 4, the width of the support groove 4 is larger than the width of the steel sheet 5. By using the structural cooperation between the limiting groove 12 and the flanging part 11, it is convenient to straighten and fix the steel sheet 5. The steel sheet 5 is limited by its own shape. The steel sheet 5, the bending part 10 and the flanging part 11 are integrally manufactured structures. Such a setting makes the processing technology of the three simpler in the production and manufacturing process, easier to be produced and manufactured, reduces the capital investment of the manufacturer. By setting the bending part 10, the flanging part 11 and the limiting groove 12 in cooperation, the bending part 10 and the flanging part 11 have two states: when the steel sheet 5 is straightened, the bending part 10 is unfolded, and at this time the flanging part 11 is received inside the limiting groove 12 for fixation, which is convenient for the scraper to be inserted into the intervertebral space. When the position of the steel sheet 5 corresponding to the support groove 4 is extruded into an arc protruding from the outer wall of the tool body 1, the flanging part 11 and the bending part 10 return to the bent state. The structure of the bending part 10 not only facilitates the medical staff to pinch the steel sheet 5 by hand for adjustment, but also the outer contour of the bending part 10 is larger than the inner wall size of the circular groove 16, ensuring that the steel sheet 5 will not slide into the inside of the tool body 1, thus ensuring the smooth progress of the operation.

[0044] By providing the support groove 4 and the steel sheet 5, there are two states between the support groove 4 and the steel sheet 5: when it is necessary to insert the tool body 1 to the intervertebral space, the steel sheet 5 is in a straightened state (as shown in Figure 1 and Figure 3 ), which is convenient for inserting the scraper to the endplate. When the scraping head 3 reaches the endplate, release the steel sheet 5 to release the limit of the flanging part 11 by the limiting groove 12. The steel sheet 5 relies on its own elasticity to recover to an arc-shaped angle at the position corresponding to the support groove 4 (as shown in Figure 2 and Figure 4 ). The support and fixation of the steel sheet 5 are realized by the cooperation of the fixing block 15 and the elastic pieces 14 at different positions. In the actual operation process, medical staff can use the above two states to expand and fix the intervertebral space, and such a fixing method is not only simple in structure but also convenient in operation.

[0045] In this embodiment, as shown in Figures 1 to 9As shown, the elastic piece 14 is a curved surface elastic structure. The cross-section of the elastic piece 14 is a "human" shaped structure. One side of the elastic piece 14 is fixedly connected to the arc-shaped groove 13 on the inner wall of the tool body 1. The cleaning component includes an upper rotating part 7 fixedly connected to the bottom of the tool body 1. The bottom of the upper rotating part 7 is rotatably connected to a lower rotating part 8. The bottom of the lower rotating part 8 is fixedly connected to a scraping head 3. A hollow groove 17 is opened at the center of the scraping head 3. The bottom of the high-definition camera 6 extends into the interior of the hollow groove 17. The elastic piece 14 is a "human" shaped curved surface elastic structure (as Figure 8 and Figure 9 shown). Such a structural setting makes the overall structure of the elastic piece 14 elastic. Under the elastic action, the elastic piece 14 can generate displacement under the pressing action of an external force and recover its deformation after the external force stops pressing. The setting of the integral structure of the elastic piece 14 and the tool body 1 makes the overall structure of the elastic piece 14 simpler and more ingenious, and is easy to manufacture. By directly rotatably connecting between the upper rotating part 7 and the lower rotating part 8, multi-angle rotation of the scraping head 3 is realized. This direct rotation connection method is mostly used for the turning connection between PVC water pipes. The direct rotation connection method and its working principle are publicly known as prior art and will not be elaborated here. The width of the support groove 4 is greater than the width of the steel sheet 5 to facilitate the rotation of the steel sheet 5. The steel sheet 5 can rotate within the range of the support groove 4 to change the angle of the scraping head 3. Since the bottom of the steel sheet 5 is fixedly connected to the inner wall of the lower rotating part 8 and the bottom of the lower rotating part 8 is fixedly connected to the scraping head 3, rotating the steel sheet 5 can drive the scraping head 3 to rotate, thereby achieving multi-angle adjustment of the scraping head 3. By setting the cooperation of the fixing block 15 and the elastic piece 14, the shape contour of the elastic piece 14 is adapted to that of the fixing block 15. When pinching the top of the steel sheet 5, the top of the steel sheet 5 undergoes elastic deformation, causing the fixing block 15 to separate from the oppositely distributed elastic piece 14. When the hand releases the steel sheet 5, it rebounds to contact the elastic piece 14, and the steel sheet 5 squeezes the elastic piece 14 inward. Using the structural cooperation between the elastic piece 14 and the fixing block 15, the fixing of the fixing block 15 is realized. The elastic piece 14 can not only fix the fixing block 15 at different heights to form different degrees of support and fixation, but also the elastic piece 14 is arranged in a whole circle. When adjusting the angle of the scraping head 3 through the fixing block 15, the steel sheet 5 drives the scraping head 3 and the fixing block 15 to move synchronously. The three can freely rotate and be fixed within the range allowed by the support groove 4 to meet the multi-degree-of-freedom direction transformation of the scraper.

[0046] In this embodiment, as Figure 5 and Figure 6As shown, the top of the scraper head 3 is connected to the inner wall of the blade body 1, and the top of the scraper head 3 is fixedly connected with hooks 9 distributed in a circumferential array. The hooks 9 are elastic structures. The circular outline size formed by the bottom of the hooks 9 is smaller than the outer outline size of the high-definition camera 6. The bottom of the scraper head 3 is symmetrically provided with oblique protrusions. The oblique protrusions are more suitable for processing the end plate and are easy to operate. Due to the upper wide and lower narrow structure of the hook 9, it is easy to clamp and fix the high-definition camera 6. At the same time, the rotation of the scraper head 3 can drive the synchronous rotation of the high-definition camera 6 to ensure the synchronization of the surgical field of view. By setting the high-definition The camera 6 cooperates with the hook 9, and the high-definition camera 6 extends to the free end of the hook 9 and continues downward. The elastic structure of the hook 9 cooperates with the outer contour of the high-definition camera 6. When the high-definition camera 6 extends to the inside of the hollow groove 17, the free end of the hook 9 is stretched open to clamp and fix the high-definition camera 6. The setting of the hook 9 is not only simple and clever in structure, but also convenient and labor-saving in actual operation. In addition, the hook 9 and the scraper head 3 are an integrated manufacturing structure. Such a setting makes the processing technology of the two simpler during the production process, easier to produce, and reduces the manufacturer's capital investment.

[0047] The workflow of the technical solution provided by the present invention is as follows:

[0048] When in use, the blade body 1 needs to be inserted into the intervertebral space first. Before the blade body 1 is ready to be inserted, the medical staff needs to pull up the steel sheet 5 by hand to make the steel sheet 5 straight and the bent portion 10 unfolded. At this time, the flange portion 11 is received into the limiting groove 12 for fixation, and the steel sheet 5 protruding in the supporting groove 4 is also stretched into the inside of the blade body 1, which is convenient for the scraper to be inserted into the intervertebral space. Then the blade body 1 is inserted into the intervertebral space of the diseased area. When the bottom of the blade body 1 reaches the intervertebral space, the steel sheet 5 is released, and the flange portion 11 and the bent portion 10 are restored to the bent state. The bent portion 10 is pinched by hand to press the steel sheet 5 downward. At this time, the position of the steel sheet 5 corresponding to the supporting groove 4 is squeezed into an arc and gradually protrudes from the outer wall of the blade body 1. The arc-shaped protrusion of the steel sheet 5 is used to open the end plates on both sides, and the fixing block 15 cooperates with the spring sheets 14 at different positions to achieve support and fixation of the steel sheet 5. A fixing block 15 and the spring sheet 14 are provided to cooperate, and the spring sheet 14 and the fixing block The shape contour of 15 is adapted. When the top of the steel sheet 5 is pinched by hand, the top of the steel sheet 5 undergoes elastic deformation, so that the fixing block 15 is separated from the oppositely distributed spring pieces 14. When the hand is released, the steel sheet 5 rebounds to contact the spring pieces 14, and the steel sheet 5 presses the spring pieces 14 inwardly. The structural cooperation between the spring pieces 14 and the fixing block 15 is utilized to fix the fixing block 15. The spring pieces 14 can not only fix the fixing block 15 at different heights to form different degrees of support and fixation, but also the spring pieces 14 are arranged in a whole circle. The cooperation between the steel sheet 5 and the supporting groove 4 is utilized. The width of the supporting groove 4 is greater than that of the steel sheet 5. This is to facilitate the rotation of the steel sheet 5. In combination with the rotational direct connection between the upper rotating part 7 and the lower rotating part 8, it can be freely rotated and fixed within the range allowed by the support groove 4. The angle of the scraper head 3 is adjusted by the positional relationship between the fixing block 15 and different spring pieces 14 to meet the multi-degree-of-freedom direction change of the scraper.

[0049] The structure of the bending portion 10 is not only convenient for medical staff to adjust the steel sheet 5 by hand, but also the outer contour of the bending portion 10 is larger than the inner wall size of the circular groove 16, ensuring that the steel sheet 5 will not slide into the inside of the blade body 1, thereby ensuring the smooth operation. The high-definition camera 6 extends to the free end of the hook 9 and continues downward, and the elastic structure of the hook 9 is coordinated with the outer contour of the high-definition camera 6. When the high-definition camera 6 extends to the inside of the hollow groove 17, the free end of the hook 9 is stretched open to clamp the high-definition camera 6. The setting of the hook 9 is not only simple and ingenious in structure, but also convenient and labor-saving in actual operation. The hook 9 and the scraper head 3 are an integrated manufacturing structure. Such a setting makes the processing technology of the two simpler during the production process, easier to be manufactured, reduces the manufacturer's capital investment, improves the accuracy and efficiency of cleaning, and greatly improves the success rate of the operation.
