[0002] In current surgical operations, especially those with extremely high requirements for positioning accuracy such as minimally invasive intracranial hematoma removal, accurately determining the position of the lesion site in the patient's body relative to the external fixation device and surgical instruments is crucial;

[0003] Existing fixation devices can play a certain role in the initial positioning of patients, but during the actual surgical operation, the patient may move due to inevitable factors (such as unconscious body movements under anesthesia, slight twisting due to pain stimulation during the operation, etc.), and the existing fixation devices cannot accurately reposition the moved patient in real time. As a result, when the surgical instruments operate based on the original positioning information, large errors will occur, seriously affecting the accuracy of the operation, increasing the surgical risk and the possibility of postoperative complications, and reducing the surgical success rate and the prognosis quality of the patient;

[0004] Therefore, we propose a minimally invasive intracranial hematoma removal orientator and a positioning method. Summary of the Invention

[0049] In one embodiment of the present invention: The limiting assembly 8 includes a third chute, a second connecting plate 82, a hydraulic rod 83, and a limiting resisting plate 84.

[0050] In one embodiment of the present invention: The processor is electrically connected to the alarm device 5, the micro optical tracking sensor 6, and the fiber optic sensor 85 respectively.

[0051] Example 1. Please refer to the attached Figure 1 - attached Figure 9 , by arranging a fiber optic sensor 85 inside the puncture frame 78, it is convenient to detect the puncture distance of the puncture needle. By arranging the strain gauge sensor 47 to detect the pressure and deformation changes generated by the movement of the body at these parts, it is used to assist in judging the movement state of the patient's body.

[0052] Example 2. Please refer to the attached Figure 1 - attached Figure 9 , by fixing two micro optical tracking sensors 6 to the top of the frame structure 3, the spatial position change of the fixed part of the body relative to the operating room can be accurately tracked, and the real-time position of the patient's trunk can be located in cooperation with other sensors.

[0053] Example 3. Please refer to the attached Figure 1 - attached Figure 9, the present invention also provides a positioning method for a minimally invasive intracranial hematoma removal orientator, including the following steps:

[0054] First, rotate the rotating column 23 out of the interior of the receiving groove 22 through the connecting plates 21 on both sides of the fixing component 2 of the device main body 1 to complete the fixation of the device main body 1;

[0055] Next, place the patient's head between the clamping components 4. At this time, the processor starts the clamping motor 41 to drive the slider 43 and the clamping plate 44 on the screw 42 to move left and right, and at the same time drives the abutting ring 46 and the strain gauge sensor 47 to move left and right for adjustment. When the height of the clamping component 4 needs to be adjusted, the processor starts the stable lifting rod 74 to complete the height adjustment of the clamping component 4.

[0056] Also, the puncture frame 78 moves up and down along the second sliding rod 75 within the frame structure 3, and the slider 72 drives the sliding plate 73 to slide stably on the first sliding rod 71, thereby driving the combined lifting of the puncture frame 78 and the clamping component 4.

[0057] Finally, the strain gauge sensor 47 provided inside the clamping component 4 records the initial positioning position. After the device main body 1, the clamping component 4, and the puncture frame 78 are positioned and clamped, select a puncture needle to penetrate into the hole of the puncture frame 78. During the puncture process, the strain gauge sensor 47 detects the initial positioning position in real time. When the error exceeds a distance of 1 mm - 2 mm, an alarm is issued through the alarm 5 to remind the surgical operator that the current puncture operation has a positioning error beyond the allowable range.

[0058] In an embodiment of the present invention: By arranging an alarm 5 inside the device main body 1, the alarm 5 is electrically connected to the processor to give an early warning in case of abnormal situations, improving the accuracy of the operation.

[0059] In an embodiment of the present invention: Rotate the rotating column 23 out of the interior of the receiving groove 22 through the connecting plates 21 on both sides of the fixing component 2, and insert the plate body into the interior of the C-shaped fastening plate body 24 for fixation, facilitating the fixation of the device main body 1.

[0060] Specifically, the strain gauge sensor 47 records the initial positioning position. After the device main body 1, the clamping component 4, and the puncture frame 78 are positioned and clamped, select a suitable puncture needle to penetrate into the hole of the puncture frame 78, and insert the selected puncture needle smoothly into the skull along the established route. The strain gauge sensor 47 detects the initial positioning position in real time. When the error exceeds a distance of 1 mm - 2 mm, an alarm is promptly issued through the alarm 5 to timely remind the surgical operator that the current puncture operation has a positioning error beyond the allowable range, so that the operator can quickly make corresponding adjustment measures, thereby ensuring the accuracy of the puncture process and the safety of the operation to the greatest extent, facilitating the improvement of the accuracy of the operation.

[0061] Specifically, the clamping motor 41 drives the slider one 43 and the clamping plate one 44 on the screw rod 42 to move left and right, and at the same time drives the abutting ring 46 and the strain gauge sensor 47 to move left and right for adjustment. The processor starts the stable lifting rod 74 to adjust the height of the clamping assembly 4. The puncture frame 78 smoothly lifts and lowers along the second sliding rod 75 within the frame structure 3. The slider two 72 drives the sliding plate 73 to stably slide on the first sliding rod 71, thereby driving the combined lifting of the puncture frame 78 and the clamping assembly 4, facilitating the improvement of the stability of clamping and positioning, enhancing the accuracy of clamping and puncture, and reducing the risk of surgical injury.

[0062] Specifically, by setting positioning bolts on both sides of the frame structure 3, the device main body 1 can be fastened. By rotating the rotating column 23, the C-shaped fastening plate body 24 can be rotated out of the outer side of the receiving groove 22, and fastening connection can be carried out using the fastening bolt 25. By setting two fixing methods, it is convenient for the fixing assembly 2 to be used in various application scenarios.

[0063] Working principle:

[0064] First, before starting the minimally invasive removal of intracranial hematoma, it is necessary to perform a cranial CT examination on the patient undergoing the operation to display the specific shape, size, location of the intracranial hematoma, and its relative relationship with surrounding brain tissues, skulls, etc., measure the coordinate information of the hematoma center in the three-dimensional space of the skull, determine the specific values of the hematoma in the anterior-posterior, left-right, and up-down directions, clarify the nature of the hematoma and the detailed conditions of the surrounding brain tissues, calculate the optimal puncture point and puncture path from the skull surface to the hematoma center, including parameters such as the puncture angle and depth. Then, by using the positioning bolts on both sides of the frame structure 3, the device main body 1 can be fastened, or by rotating the rotating column 23, the C-shaped fastening plate body 24 can be rotated out of the outer side of the receiving groove 22, and fastening connection can be carried out using the fastening bolt 25. By setting two fixing methods, it is convenient for the fixing assembly 2 to be used in various application scenarios.

[0065] Place the patient's head between the clamping assemblies 4. At this time, the processor starts the clamping motor 41 to drive the slider one 43 and the clamping plate one 44 on the screw rod 42 to move left and right, and at the same time drives the abutting ring 46 and the strain gauge sensor 47 to move left and right for adjustment. When it is necessary to adjust the height of the clamping assembly 4, the processor starts the stable lifting rod 74 to adjust the height of the clamping assembly 4. At the same time, the puncture frame 78 smoothly lifts and lowers along the second sliding rod 75 within the frame structure 3. The slider two 72 drives the sliding plate 73 to stably slide on the first sliding rod 71, thereby driving the combined lifting of the puncture frame 78 and the clamping assembly 4, facilitating the improvement of the stability of clamping and positioning, enhancing the accuracy of clamping and puncture, and reducing the risk of surgical injury.

[0066] At this time, the strain gauge sensor 47 arranged inside the clamping assembly 4 records the initial positioning position. After the device main body 1, the clamping assembly 4, and the puncture frame 78 are positioned and clamped, a suitable puncture needle is selected and inserted into the hole of the puncture frame 78. At this time, the staff slides the connecting plate two 82 and the slider four 81 in the limiting assembly 8 to slide inside the third chute. After initially determining the puncture distance through CT, the processor is started. Distance parameters are set in advance in the processor. At this time, the processor and the fiber optic sensor 85 in the puncture frame 78 sense each other. After the puncture reaches the set distance, the fiber optic sensor 85 issues an instruction to the processor, and the selected puncture needle is inserted into the skull smoothly along the established route, avoiding damaging the brain tissue during the process. During the puncture process, the strain gauge sensor 47 detects the initial positioning position in real time. When the error exceeds the 1 mm - 2 mm distance set by the processor, an alarm is given in a timely manner through the alarm 5, timely reminding the surgical operator that there is a positioning error beyond the allowable range in the current puncture operation, so that the operator can quickly make corresponding adjustment measures, thus ensuring the accuracy of the puncture process and the safety of the operation to the greatest extent;

[0067] When the patient's vital signs are abnormal, such as a sharp increase in blood pressure or blood oxygen saturation, etc., which may endanger life, and monitoring means such as ultrasound show that acute cerebral edema is progressing rapidly, and there are serious risks in continuing the operation. After multiple path corrections, the safe range still cannot be reached. When the risk of continuing the puncture is greater than the risk of withdrawing the needle and re-puncturing, the needle withdrawal operation is carried out. At this time, the staff needs to maintain the current depth, observe for a period of time, slowly withdraw and inject hemostatic gel synchronously, and monitor the intracranial pressure change throughout the process to minimize the risk brought by needle withdrawal;

[0068] When the error exceeds the allowable distance set by the processor, the staff will first try to correct it in situ, use the special material of the puncture needle to make a gradual angle correction, and then repeat the above steps to relax the limit of the puncture needle by the hydraulic rod 83 and the limit plate 84. When the puncture height needs to be adjusted too high, the stable lifting rod 74 is started to descend, and the puncture frame 78 is steadily lowered along the second slide bar 75 in the frame structure 3. The slider 72 drives the sliding plate 73 to slide steadily on the first slide bar 71, thereby driving the puncture frame 78 and the clamping assembly 4 to jointly descend. The opposite operation is performed when it is raised. During the operation, the patient's vital signs are observed in real time, and the causes of the puncture deviation are carefully analyzed. According to the patient's latest The imaging data, re-formulate the puncture plan, select a more appropriate puncture point and puncture path, repeat the above operation again, when the puncture needle needs to be pulled out, gradually relax the hydraulic rod 83, thereby relaxing its clamping and limiting effect on the puncture needle, avoiding additional pulling force or impact force on the puncture needle due to too fast operation, when the hydraulic rod 83 and the limiting plate 84 completely relax the limit of the puncture needle, hold the holding part of the puncture needle gently and steadily with both hands, and pull the puncture needle out of the hole of the puncture frame 78 at a uniform and slow speed in the opposite direction of the path when the puncture needle enters, and keep the puncture needle in a straight line to avoid deflection or twisting, so as to prevent unnecessary damage to the tissue around the puncture channel;

[0069] After the puncture needle is withdrawn, immediately conduct a preliminary inspection of the puncture needle to check for any bends, damage, etc., and place it properly to prevent the puncture needle from being contaminated or causing accidental injury to other personnel. At the same time, quickly apply pressure to the puncture point to stop bleeding. Use sterile gauze or other suitable hemostatic materials, apply appropriate pressure, and press the puncture point for about 5 to 10 minutes until there is no obvious bleeding at the puncture point. Strictly disinfect the puncture point and surrounding areas. Use iodine tincture and other high-efficiency disinfectants to perform circular disinfection from the inside to the outside with the puncture point as the center. The disinfection range should cover an area with a diameter of at least 5 cm around the puncture point to prevent infection. To prevent the occurrence of hematoma, according to the specific situation of the puncture point, choose appropriate wound covering materials, such as sterile Band-Aid, sterile gauze, etc., properly bandage the puncture point, ensure that the wound is in a clean and dry environment, and closely observe the patient's reaction after the puncture needle is withdrawn, including changes in vital signs, local bleeding, swelling, etc. If there is any abnormality, appropriate treatment measures should be taken in time. If bloody fluid flows out, it preliminarily proves that the puncture is successful. Then insert a suitable drainage tube through the puncture needle, so that the front end of the drainage tube is located in the center of the hematoma or a suitable drainage position, and then properly fix the drainage tube to prevent it from shifting. At this point, the entire work process is completed.
