Description

Technical Field

[0001] The utility model belongs to the technical field of spinal surgery, and particularly relates to a guide plate for spinal surgery. Background Technique

[0002] Spinal surgery is an important discipline in the medical field that focuses on the diagnosis and treatment of spinal-related diseases and injuries. Its scope covers the entire spinal region from the cervical vertebrae to the lumbar vertebrae, dealing with a wide variety of diseases, including spinal fractures, dislocations, intervertebral disc herniations, spinal stenosis, scoliosis, spinal tumors, etc. Spinal surgeons use advanced medical techniques such as minimally invasive surgery, spinal fusion, and internal fixation to restore the normal structure and function of the spine, effectively relieve the patient's pain, significantly improve nerve function, and greatly enhance the patient's quality of life. In the diagnosis process, with the help of imaging examination methods such as X-rays, CT scans, and magnetic resonance imaging (MRI), the pathological conditions of the spine can be accurately evaluated. However, spinal surgery is usually highly complex and risky, which requires doctors to have excellent technical skills and rich practical experience.

[0003] Currently, there is a problem of inconvenient fixation in the actual use of spinal minimally invasive puncture guide plates. The fixed guide plate needs to be repeatedly fixed during the adjustment of the puncture position and angle, which causes greater harm to the patient. For example, the Chinese patent with the publication number "CN116531063A" discloses a 3D printed minimally invasive puncture guide plate for spinal surgery. The 3D printed minimally invasive puncture guide plate for spinal surgery includes a guide plate base, and a puncture guide plate body composed of a guide plate part and a connecting plate is arranged at the lower end of the guide plate base. A puncture guiding column and a needle hole are arranged at the lower end of the guide plate part, and the connecting plate is connected to the lower end of the guide plate base with a locking bolt. The puncture guide plate body is formed by multi-layer composite 3D printing. Through related structures, the position and angle can be adjusted to achieve accurate puncture, reduce patient harm, and also have various good performances, greatly improving the product quality.

[0004] However, during the use of the above device, although it can play an auxiliary adjustment role, it can only perform linear displacement adjustment. In actual applications, it is impossible to flexibly adjust the puncture angle according to actual puncture needs. When lateral inclined puncture is required, obviously the above device cannot be flexibly adapted. Therefore, there are certain defects and deficiencies in the existing technical means, and it needs to be improved. Summary of the Utility Model

This special shape design enables the linkage guide plate 343 to be accurately driven to move when the guide plate 341 is rotated, facilitating quick disassembly and assembly. The adjusting armrest 344 on the front and the anti-slip grip sleeve on its outer surface increase the friction force, making it convenient for the user to apply force, making the adjustment process easier and more accurate, thereby realizing flexible control of the adjusting ball 4 and improving the operation convenience and controllability of the entire device.

[0031] Principle and advantages of use: By setting the angle adjustment mechanism 3, the device can be used to rotate the guide plate 341 by twisting the adjustment armrest 344. The two ends of the guide plate 341 are against the guide plate. At this time, the guide plate 341 is elliptical, and the inner end of the guide plate is set in an isosceles triangle. At this time, the guide plate 341 can be driven to move in a linkage manner to move the guide plate toward both sides. The outward movement of the guide plate can drive the connecting frame 342 to push the limit block 333 toward the outside. The outward movement of the limit block 333 can drive the suction cup 334 to separate from the adjustment ball 4. At this time, the rotation adjustment can be adjusted. The adjusting ball 4 is adjusted and rotated to flexibly adjust the inclination angle of the puncture catheter 6. After the angle adjustment is completed, it is only necessary to loosen the adjusting armrest 344. At this time, the limit spring 332 is reset to drive the limit block 333 to contact the suction cup 334 and fit the outer side of the adjusting ball 4. The suction cup 334 and the adjusting ball 4 are in contact, and the adjusting ball 4 can be assisted to be fixed again, so that the whole device can be adjusted by rotating the adjusting ball 4, thereby facilitating the adjustment of the inclination angle of the puncture catheter 6, which can enable the device to be flexibly tilted to guide the puncture, and can improve the overall adaptability of the device during use;

[0032] By setting the adjustment mechanism 7, the device can be used to adjust and twist the adjustment hand wheel 75 during use. The rotation of the adjustment hand wheel 75 can assist in adjusting the rotation of the screw rod 72. The rotation of the screw rod 72 can drive the slider 73 to slide on the top of the side plate 71. The sliding of the slide plate 82 can flexibly adjust the sliding of the driving slide 31. The sliding of the adjusting slide 31 can assist in driving and adjusting the lateral displacement of the puncture catheter 6, so that the device can flexibly adjust the puncture position and puncture angle according to the use requirements during use, which can further improve the overall use adaptability of the device. In addition, during use, the inner side of the sleeve is slidably connected to the slide plate 82. By adjusting the slide plate 82 to slide on the inner side of the sleeve, the total length of the slide plate 82 and the sleeve can be flexibly adjusted. At this time, the twisting of the hand-tightened screw 83 can assist in fixing the sleeve frame 81 and the slide 31, so that the device can have better stability as a whole during use, and the device can flexibly adjust its use height, which can improve the overall use convenience of the device.
