Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a 3D printed guide plate for cerebral hemorrhage. Background Art

[0002] Cerebral hemorrhage is a common and critical neurosurgery emergency. With the development of precision medicine, puncture to drain hematomas and relieve intracranial pressure has become widely used due to its minimally invasive, safe, and rapid advantages. Accurate and safe puncture is essential for improving efficacy and reducing surgical trauma. However, conventional punctures often lead to deviations in puncture location and distance due to individual differences and varying physician experience, and can even lead to puncture failure and necessitate craniotomy. The 3D-printed cerebral hemorrhage puncture positioning guide is a commonly used surgical aid in primary care hospitals because it does not change the physician's routine surgical procedures, is quick to align, is easy to use, and can accurately locate hematomas. However, cerebral hemorrhages are often dangerous and progress rapidly, so clinically, surgery is usually performed within two hours of the patient's admission to alleviate the condition. However, the existing mask-type or ear-hanging puncture positioning guides are large in size and take about 3 hours to print. In addition, the time for guide design and disinfection will be even longer. Using guides for positioning may miss the best time for surgery. Therefore, they are not suitable for patients with time-limited surgery. This defect seriously limits the clinical application opportunities of cerebral hemorrhage puncture positioning guides.

[0003] The intracranial hematoma puncture and drainage guide disclosed in the Chinese utility model patent application disclosure CN211534690U, although the device solves the shortcomings of positioning deviation, puncture error, and incomplete drainage caused by inaccurate puncture depth during traditional blind puncture surgery, saves time spent on complicated preoperative preparation operations such as intraoperative measurement and locating lesions, and shortens the overall planning time, but the existing device does not solve the problems of being unable to place the guide during surgery due to excessive medical supplies required, the position of the guide body cannot be fully positioned with the required surgical position during surgery, resulting in an offset in the placement position of the guide body affecting the surgical effect, and the displacement of the guide body due to touching the guide body during surgery after the guide body is placed at the patient's required surgical position, affecting the surgical operation. Therefore, we propose a new device to solve the above problems. Utility Model Content

During use, the curvature of the guide body 1 can be increased according to the CT scan to adapt to the patient's required surgical position. The size and position of the hematoma can be determined through three-dimensional reconstruction of the skull and hematoma, and the puncture channel can be designed. The guide body 1 is fitted with the patient's head shape through the special structure and position of the patient's nasal bone and brow bone to ensure that the position of the guide body 1 is consistent with the preoperative design. In order to increase the accuracy of the puncture, a positioning structure 2 is designed. One side of the guide body 1 is designed to be a hemispherical protrusion to prevent the error of the guide placement position caused by local skin bulge after local anesthesia. By placing the required docking medical supplies on the upper surface of the lower splint 5 and tightening the splint bolt 4, The upper splint 3 is moved upward so that the upper splint 3 and the lower splint 5 can clamp and fix the required docking medical supplies, which solves the problem that too many medical supplies are required and cannot be placed when performing surgery on the patient, and achieves the effect of clamping and fixing the required docking medical supplies by the upper splint 3 and the lower splint 5.

The laser irradiated by the left laser pen 15 is overlapped with the left gasket 17. Then the left magnet piece 16 is magnetically connected to the left gasket 17 to complete the positioning of the guide body 1 to the patient's desired surgical position. This solves the problem that the position of the guide body 1 cannot be fully positioned with the desired surgical position during the operation on the patient, resulting in the deviation of the placement position of the guide body 1 and affecting the surgical effect. The effect of fixing the left gasket 17 and the right gasket 11 to the desired surgical position before the operation to position them and then fixing the guide body 1 is achieved, which greatly enhances the accuracy of the placement of the guide body 1. Use a marker to mark the center of gasket 17 and right gasket 11. During surgery, remove the left gasket 17 and right gasket 11. According to the preoperative design, the left laser pointer 15 and the right laser pointer 9 point to the center of the left gasket 17 and right gasket 11. If the guide body 1 is found to be offset in the fitting position, the guide body 1 can be fine-tuned and reset. It is worth noting that before the patient's CT scan, the pre-production reference positioning is required. The left gasket 17 and the right gasket 11 are the make points, which can be attached to the patient's skin. Therefore, the position of the make points on the 3D image cannot be determined in advance. The overall shape of the device needs to be designed based on the position of the make points in the design software.

[0027] like Figure 5 As shown, in this embodiment, one side of the guide body 1 is fixedly connected to a collection box 18, and the interior of the collection box 18 is rotatably connected to a docking shaft 19, and a restraining belt 20 is fixedly connected to the surface of the docking shaft 19, and a positioning rod 21 is inserted into the interior of the docking shaft 19. A docking hole is opened on the upper surface of the collection box 18, and the size of the docking hole is adapted to the size of the positioning rod 21. During use, after the guide body 1 is placed, the restraining belt 20 is hooked on the patient's ear, and then the docking shaft 19 is rotated to tighten the restraining belt 20. After the restraining belt 20 is tightened, it is passed through the positioning rod 21 penetrates the docking hole and the docking shaft 19 at the same time, so that the docking shaft 19 cannot rotate. Repeat the above operation to fix the patient's other ear, so as to enhance the stability of the guide body 1. This solves the problem that after the guide body 1 is placed in the patient's desired surgical position, the guide body 1 is moved due to touching the guide body 1 during the operation, which affects the surgical operation. After the guide body 1 is placed, the device can be connected and fixed to the ear by tightening the restraining belt 20, thereby enhancing the stability of the guide body 1, which greatly reduces the displacement of the guide body 1 during the operation.

[0028] This utility works as follows:

[0029] During use, the curvature of the guide body 1 can be increased according to the CT scan to adapt to the patient's required surgical position.

The guide body 1 is designed to fit the patient's head shape through the special structure and position of the patient's nasal bone and brow bone to ensure that the position of the guide body 1 is consistent with the preoperative design. In order to increase the accuracy of the puncture, a positioning structure 2 is designed. One side of the guide body 1 is designed as a hemispherical protrusion to prevent local skin bulge after local anesthesia. The error in the placement of the guide plate is corrected by placing the required docking medical supplies on the upper surface of the lower splint 5, tightening the splint bolt 4, and moving the upper splint 3 upward so that the upper splint 3 and the lower splint 5 can clamp and fix the required docking medical supplies. The right gasket 11 and the left gasket 17 are placed at the position where the patient needs to place the guide plate body 1, and the right spring buckle 7 is pressed, and then the right positioning plate 8 is docked with the right card plate 6, so that the right spring buckle 7 passes through the right hole to fix the right positioning plate 8. The laser irradiated by the right laser pen 9 is aligned with the right gasket 11. Overlap, then magnetically connect the right magnet sheet 10 with the right gasket 11, press the left spring buckle 13, and then dock the left positioning plate 14 with the left card plate 12, so that the left spring buckle 13 passes through the left hole to fix the left positioning plate 14, and overlap the laser irradiated by the left laser pen 15 with the left gasket 17, and then magnetically connect the left magnet sheet 16 with the left gasket 17 to complete the positioning of the guide body 1 to the patient's required surgical position. The left gasket 17 and the right gasket 11 are marked in the middle with a marker, and the left gasket 17 and the right gasket 11 are removed during the operation. According to the preoperative design, the left laser pen 15 and the right laser pen 9 point to the center of the left gasket 17 and the right gasket 11. If it is found that the fitting position of the guide body 1 is offset, the guide body 1 can be fine-tuned and reset. The restraint belt 20 is hooked on the patient's ear, and then the docking shaft 19 is rotated to tighten the restraint belt 20. After the restraint belt 20 is tightened, it passes through the docking hole and the docking shaft 19 at the same time through the positioning rod 21, so that the docking shaft 19 cannot rotate. Repeat the above operation to fix the other ear of the patient to enhance the stability of the guide body 1.
