The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, so they are only examples and cannot be used to limit the protection scope of the present application.

[0057] Referring to "embodiment" in this article means that the specific features, structures or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application. The term "embodiment" appearing in various positions in the specification does not necessarily refer to the same embodiment, nor does it particularly limit its independence or relevance to other embodiments. In principle, in the present application, as long as there is no technical contradiction or conflict, the technical features mentioned in each embodiment can be combined in any way to form corresponding implementable technical solutions.

[0058] Unless otherwise defined, the meanings of the technical terms used herein are the same as those commonly understood by those skilled in the technical field to which this application belongs; the use of relevant terms herein is only for describing specific embodiments and is not intended to limit this application.

[0059] In the description of this application, the term "and / or" is an expression used to describe the logical relationship between objects, indicating that there can be three relationships. For example, the minimally invasive puncture and drainage device for cerebral hemorrhage and / or B means: there is a minimally invasive puncture and drainage device for cerebral hemorrhage, there is B, and there is a situation where both the minimally invasive puncture and drainage device for cerebral hemorrhage and B exist at the same time. In addition, the character " / " in this article generally represents an "or" logical relationship between the associated objects before and after.

[0060] In this application, terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual quantitative, primary-secondary, or sequential relationships between these entities or operations.

[0061] Without further limitation, in this application, the open-ended expressions such as "include", "comprise", "have" or other similar ones used in a statement are intended to cover non-exclusive inclusion. These expressions do not exclude that there may be additional elements in the process, method or product including the said elements, so that the process, method or product including a series of elements may not only include those defined elements, but also include other elements not explicitly listed, or also include elements inherent to this process, method or product.

[0062] The same as the understanding in the "Examination Guidelines", in this application, expressions such as "greater than", "less than", "exceeding" are understood not to include the number itself; expressions such as "above", "below", "within" are understood to include the number itself.

[0065] As Figure 1 shown, for the existing positioning guide plate 1, it is necessary to set each fixing post 13 and a puncture positioning post 14. The disinfection of the positioning guide plate of the puncture positioning post is difficult. After local anesthesia, the skin at the puncture site bulges, and the fit of the positioning guide plate of the puncture positioning post is poor. It is necessary to print the fixing post and the puncture positioning post, and the printing efficiency is low. It is difficult to withdraw the drainage tube.

[0066] Problem of guide plate disinfection: Traditional 3D printing guide plates mostly adopt the fused deposition modeling (FDM) technology, and the materials are PLA or ABS plastics. High-temperature and high-pressure disinfection (≥121 °C) will cause the guide plate to soften and deform, while low-temperature plasma disinfection is costly, and the penetration of iodophor immersion is insufficient. Moreover, the inner wall of the puncture tract is often rough and the inner diameter is small, so there is a possibility of incomplete disinfection and an increase in the infection rate.

[0067] Fitting deviation: After local anesthesia, the skin at the puncture site bulges, resulting in a gap between the guide plate and the scalp contact surface. The intraoperative displacement error of the guide plate can reach 2 - 5 mm, directly affecting the puncture accuracy.

[0068] Low printing efficiency: Conventional guide plates need to print large head-shaped contours, and the printing time is 1.5 - 2 hours, which cannot meet the timeliness requirements of emergency surgeries.

[0069] Difficult withdrawal of the drainage tube: The existing drainage tube has an anti-slip bulge at the end. If the diameter of the puncture tract is designed slightly larger than the bulge (for easy withdrawal), the puncture accuracy will decrease; if the puncture tract is designed slightly larger than the drainage tube, violent pulling is required during withdrawal, which is likely to cause the displacement of the end position of the tube.

[0070] In view of this, the embodiments of the present application provide a minimally invasive puncture drainage device and a drainage method for cerebral hemorrhage. The positioning guide plate 1 includes a positioning body 11, a nose bridge positioning part 12 and a fixing column 13. The nose bridge positioning part 12 and the fixing column 13 are respectively arranged on the positioning body 11. The fixing mechanism 2 includes an installation sleeve 21, a cross bar 22, a clamping assembly 23 and a first fastener 24. The inner diameter of the installation sleeve 21 is larger than the outer diameter of the fixing column 13. The installation sleeve 21 is sleeved on the fixing column 13. The first fastener 24 is arranged on the installation sleeve 21. The first fastener 24 is used to fix the installation sleeve 21 on the fixing column 13. One end of the cross bar 22 is connected to the top of the installation sleeve 21. The clamping assembly 23 is connected to the other end of the cross bar 22. The clamping assembly 23 includes a clamping member 231 and a second fastener 232. The fixed end of the clamping member 231 is connected to the cross bar 22. The second fastener 232 is connected to the clamping end of the clamping member 231. A puncture channel 31 is arranged on the puncture positioning member 3. The puncture positioning member 3 is arranged inside the clamping end of the clamping member 231. The second fastener 232 is used to control the clamping end of the clamping member 231 to clamp or release the puncture positioning member 3. It is not necessary to provide a puncture positioning column 14 on the positioning guide plate 1, and it is not necessary to disinfect the positioning guide plate 1 at the puncture positioning column 14, avoiding the problem of poor fitting between the positioning guide plate 1 of the puncture positioning column 14. Only the fixing column 13 needs to be printed, improving the printing efficiency, and the withdrawal of the drainage tube 4 is simple.

[0071] According to some embodiments of the present application, please refer to Figures 1 to 10, this embodiment relates to a minimally invasive puncture drainage device for cerebral hemorrhage, including a positioning guide plate 1, a fixing mechanism 2, and a puncture positioning member 3. The positioning guide plate 1 includes a positioning body 11, a nasal bridge positioning portion 12, and a fixing column 13. The nasal bridge positioning portion 12 and the fixing column 13 are respectively arranged on the positioning body 11; the fixing mechanism 2 includes an installation sleeve 21, a cross bar 22, a clamping assembly 23, and a first fastener 24. The inner diameter of the installation sleeve 21 is larger than the outer diameter of the fixing column 13. The installation sleeve 21 is sleeved on the fixing column 13, and the first fastener 24 is arranged on the installation sleeve 21. The first fastener 24 is used to fix the installation sleeve 21 on the fixing column 13. One end of the cross bar 22 is connected to the top of the installation sleeve 21, and the clamping assembly 23 is connected to the other end of the cross bar 22. The clamping assembly 23 includes a clamping member 231 and a second fastener 232. The fixed end of the clamping member 231 is connected to the cross bar 22, and the second fastener 232 is connected to the clamping end of the clamping member 231; a puncture channel 31 is arranged on the puncture positioning member 3, and the puncture positioning member 3 is arranged inside the clamping end of the clamping member 231. The second fastener 232 is used to control the clamping end of the clamping member 231 to clamp or loosen the puncture positioning member 3.

[0072] In some embodiments, such as Figure 1 and Figure 6 shown, a puncture channel guiding mark 15 is arranged on the positioning body 11. The two ends of the puncture channel guiding mark 15 respectively face the fixing column 13 and the puncture channel 31. The extending direction of the puncture channel guiding mark 15 is the moving direction of the puncture channel 31; the puncture channel guiding mark 15 facilitates pointing to the moving direction of the puncture channel 31;

[0073] In some embodiments, the positioning guide plate 1 is 3D printed. However, since the puncture positioning column 14 is cancelled on the positioning guide plate 1, the positioning guide plate 1 can have more versatility, and it is not necessary to print a positioning guide plate 1 for each patient;

[0074] In some embodiments, such as Figure 9 shown, the installation sleeve 21 is a telescopic structure. The installation sleeve 21 can change its height in the first direction (the direction indicated by the arrow a in the figure). The cross bar 22 can also be a telescopic structure and can change the length of the cross bar 22 in the second direction (the direction indicated by the arrow b in the figure). The puncture positioning member 3 can be a telescopic structure and can change the height of the puncture positioning member 3 in the first direction (the direction indicated by the arrow a in the figure), which can adapt to more patients' puncture drainage surgeries;

[0075] In other embodiments, the installation sleeve 21, the cross bar 22, and the puncture positioning member 3 can have many models, and the installation sleeve 21, the cross bar 22, and the puncture positioning member 3 can be replaced according to the actual situation;

The first circular groove 331 and the second circular groove 341 cooperate with each other to form a puncture channel 31, which facilitates the disassembly of the puncture positioning member 3 instead of pulling the drainage tube 4 to withdraw the drainage tube 4 from the puncture channel 31 of the puncture positioning member 3.

[0078] In this embodiment, the positioning guide plate 1 includes a positioning body 11, a nasal bridge positioning part 12, and a fixing column 13.

The second threaded hole 212 passes through the mounting sleeve 21 along a second direction (the direction indicated by arrow b in the figure), and the second threaded hole 212 communicates with the first mounting hole 213.

[0094] In this way, the fixing post 13 is located within the first mounting hole 213, facilitating the installation of the mounting sleeve 21 on the fixing post 13. The second threaded hole 212 and the first mounting hole 213 facilitate the installation of the cross bar 22.

[0095] According to some embodiments of the present application, optionally, as Figure 4 and Figure 5As shown, the clamping member 231 includes a hinge seat 2311 and a hinge member 2312.

The first arc portion 2313 and the second arc portion 2315 are in contact with the puncture positioning member 3. The connecting portion 2314 is connected to the other end of the cross bar 22. There is a gap between the connecting portion 2314 and the puncture positioning member 3, which can accept partial deformation of the puncture positioning member 3 and facilitate clamping of the puncture positioning member 3.

[0098] According to some embodiments of the present application, optionally, the connecting portion 2314 includes a first vertical section 23141, a second vertical section 23142, and a third vertical section 23143.

[0099] In this way, the first vertical section 23141, the second vertical section 23142, and the third vertical section 23143 form a groove structure. There is a gap between the second vertical section 23142 and the puncture positioning member 3. The second vertical section 23142 is connected to the other end of the cross bar 22, which can accept partial deformation of the puncture positioning member 3 and facilitate clamping of the puncture positioning member 3.

[0100] The puncture positioning member 3 can be made of an elastic material, specifically made of rubber;

[0101] According to some embodiments of the present application, optionally, the other end of the hinge seat 2311 is provided with a first connection groove 2316.

[0102] In this way, by rotating the butterfly-shaped rotating member 2322, the puncture positioning member 3 between the hinge seat 2311 and the hinge member 2312 can be clamped, facilitating the disassembly of the puncture positioning member 3. The other end of the hinge member 2312 can be opened to take out the puncture positioning member 3, and one end of the third threaded column 2321 is always connected to the connection column 2317.

[0104] The clamping portion 332 facilitates the clamping by the clamping member 231. Both ends of the first positioning block 33 are provided with protrusions, and both ends of the second positioning block 34 are provided with grooves. The first positioning block 33 forms a puncture positioning member 3 by the cooperation of the protrusions and the grooves of the second positioning block 34, facilitating the positioning of the first positioning block 33 and the second positioning block 34;

[0105] In this way, a complete cylindrical puncture positioning member 3 can be formed by the first positioning block 33 and the second positioning block 34. The first positioning block 33 and the second positioning block 34 are detachable, facilitating the disinfection of the puncture channel 31 in the puncture positioning member 3.

After disassembling the puncture positioning member 3, the drainage tube 4 can be directly taken out, making the withdrawal of the drainage tube 4 simple without violent pulling.

[0106] As Figure 10 shown in, this embodiment also provides a minimally invasive puncture drainage method for cerebral hemorrhage, including the minimally invasive puncture drainage device for cerebral hemorrhage as described in any one of the above, including the following steps:

[0107] Import the patient's head image into the 3D Slicer software, use the software to segment the hematoma, plan the puncture path, measure the puncture depth, and use the software to move the puncture path. The moving distance is consistent with the distance between the center of the installation sleeve 21 and the center of the puncture positioning member 3.

[0108] Attach the positioning guide plate 1 to the patient's scalp, cover and fix it with an iodine-containing film, install the fixing mechanism 2 through the fixing column 13, clamp the puncture positioning member 3 through the clamping assembly 23 of the fixing mechanism 2, mark the puncture position, and use a hand drill to drill a hole along the puncture direction.

[0109] Insert the drainage tube 4 according to the measured puncture depth, aspirate to verify whether it reaches the hematoma cavity. If it reaches the hematoma cavity, disassemble the minimally invasive puncture drainage device for cerebral hemorrhage, release the drainage tube 4 and fix it.

[0110] In the actual application scenario, the minimally invasive puncture drainage device and drainage method for cerebral hemorrhage are mainly used in the treatment process of patients with cerebral hemorrhage. After the patient is sent to the hospital, it is initially diagnosed as cerebral hemorrhage and meets the indications for minimally invasive puncture drainage surgery. At this time, the technical solution of the present invention needs to be used for surgical operations.

[0111] Preoperative Preparation

[0112] Import the patient's head CTA / CT image (slice thickness 1mm) in DICOM format into the 3D-Slicer software, and use the "Segment Editor" module to segment the hematoma. Plan the puncture path: avoid large blood vessels, and design the end of the puncture tract at the hairline. Measure the puncture depth; translate the designed puncture channel 31: use the Transform module to move the channel, and the moving distance is consistent with the distance between the center of the installation sleeve 21 and the center of the puncture positioning member 3 in the above embodiment.

[0113] Specifically, import the patient's head image (such as a CT image, stored in DICOM format) into the 3DSlicer software. The software operator uses the segmentation tool in the software to carefully segment the hematoma area in the patient's brain, accurately plan the puncture path through the measurement function of the software, and accurately measure the puncture depth. Then, according to the path movement function of the software, move the planned puncture path a certain distance, and this moving distance is consistent with the distance between the center of the installation sleeve 21 and the center of the puncture positioning member 3. The purpose of this step is to simulate the position of the puncture positioning member 3 in the actual operation, so as to perform the puncture operation more accurately later.

[0114] Print the guide plate. Use a 3D printer and select PLA material to print only the core area. It takes about 30 minutes.

[0115] Device preparation: Prepare the minimally invasive puncture and drainage device for cerebral hemorrhage of the present invention. Check whether each component such as the positioning guide plate 1, the fixing mechanism 2, the puncture positioning member 3, etc. is intact, and whether the connection parts 2314 are flexible and firm. Ensure that the threaded connections of components such as the installation sleeve 21, the cross bar 22, the clamping assembly 23, etc. are smooth, and the first fastener 24, the second fastener 232, etc. can work normally.

[0116] Surgical operation

[0117] Fix the positioning guide plate 1: Closely fit the positioning guide plate 1 to the patient's scalp so that the nasal bridge positioning part 12 is accurately located at the patient's nasal bridge, which helps to ensure the stability and accuracy of the positioning guide plate 1. Cover the positioning guide plate 1 with an iodine-containing film and fix it on the patient's scalp. The iodine-containing film can not only play a fixing role, but also has the function of disinfection and sterilization, which can reduce the risk of surgical infection.

[0118] Install the fixing mechanism 2 and the puncture positioning member 3: Install the fixing mechanism 2 through the fixing column 13 on the positioning guide plate 1. Sleeve the installation sleeve 21 on the fixing column 13. The inner diameter of the installation sleeve 21 is larger than the outer diameter of the fixing column 13, so that the installation sleeve 21 can be flexibly adjusted in position on the fixing column 13. After adjusting the position of the installation sleeve 21, use the first fastener 24 to fix the installation sleeve 21 on the fixing column 13. In this embodiment, the fixing column 13 is a cylindrical structure, the installation sleeve 21 is provided with a first threaded hole 211, and the first fastener 24 includes a first threaded column 241 and a rotating part 242. Rotate the rotating part 242 to thread the first threaded column 241 with the first threaded hole 211. The other end of the first threaded column 241 passes through the first threaded hole 211 and contacts the fixing column 13, thereby realizing the firm fixation of the installation sleeve 21. If there are more than two first threaded holes 211 on the installation sleeve 21, appropriate threaded holes can be selected for fixation according to the actual situation to increase the stability of the fixation.

[0119] One end of the cross bar 22 is fitted with the second threaded hole 212 at the top of the mounting sleeve 21 through the second threaded post 221, realizing the detachable connection between the cross bar 22 and the mounting sleeve 21. Place the puncture positioning member 3 inside the clamping end of the clamping assembly 23. The clamping assembly 23 includes a hinge seat 2311 and a hinge member 2312. One end of the hinge member 2312 is hinged to one end of the hinge seat 2311, and the other end is connected to the other end of the hinge seat 2311 through the second fastener 232. In this embodiment, a first connection groove 2316 is provided at the other end of the hinge seat 2311, a connection post 2317 is provided inside the first connection groove 2316, both ends of the connection post 2317 are rotatably connected to the inner walls on both sides of the first connection groove 2316, a second connection groove 2318 is provided at the other end of the hinge member 2312, the second fastener 232 includes a third threaded post 2321 and a butterfly rotating member 2322. Rotate the butterfly rotating member 2322 to connect one end of the third threaded post 2321 to the connection post 2317, and the other end passes through the second connection groove 2318 and is threadedly connected to the butterfly rotating member 2322, thereby controlling the clamping end of the clamping member 231 to clamp the puncture positioning member 3.

[0120] Puncture positioning and drilling: After fixing the puncture positioning member 3 through the clamping assembly 23 of the fixing mechanism 2, mark the puncture position on the patient's scalp according to the position of the puncture channel 31 on the puncture positioning member 3. Use a hand drill to drill along the puncture direction indicated by the puncture channel 31. During the drilling process, it is necessary to keep the hand drill stable to ensure the accuracy of the drilling direction.

[0121] Insert the drainage tube 4: According to the previously measured puncture depth, slowly insert the drainage tube 4 into the patient's brain through the puncture channel 31. During the insertion process, pay attention to avoiding the drainage tube 4 from being twisted or damaging the surrounding tissues. After the insertion is completed, verify whether the drainage tube 4 reaches the hematoma cavity through aspiration. If the aspirated liquid is bloody and the color and properties are consistent with the hematoma, it indicates that the drainage tube 4 has reached the hematoma cavity.

[0122] Postoperative treatment: After confirming that the drainage tube 4 reaches the hematoma cavity, disassemble the minimally invasive puncture drainage device for cerebral hemorrhage, release the drainage tube 4 from the puncture channel 31 of the puncture positioning member 3, and properly fix it on the patient's scalp. When fixing the drainage tube 4, pay attention to avoiding the drainage tube 4 from shifting or falling off to ensure the smooth progress of the drainage process.

[0123] The minimally invasive puncture drainage method for cerebral hemorrhage in this embodiment does not require the puncture positioning post 14 to be provided on the positioning guide plate 1, and does not require the positioning guide plate 1 at the puncture positioning post 14 to be disinfected, avoiding the problem of poor fitting between the positioning guide plate 1 of the puncture positioning post 14. Only the fixing post 13 needs to be printed, improving the printing efficiency, and the drainage tube 4 is easy to withdraw.
