Description

Technical Field

[0001] The present application relates to the technical field of minimally invasive cranial surgery, and more particularly, to a guiding device and a preparation method for minimally invasive cranial surgery. Background Art

[0002] Some cranial nerve surgical diseases such as hypertension can cause intracranial hypertension, edema, and bleeding. Usually, a part of the skull needs to be removed to reduce intracranial pressure and save the patient's life. In recent years, with the development of science and technology and the improvement of microsurgical and imaging technologies, neurosurgery has entered a new era of precision and minimally invasive surgery. The keyhole technique is gradually adopted to deal with intracranial lesions, such as puncture drainage, intracranial catheterization, and intracranial lesion biopsy, so as to minimize the exposure and damage to intracranial structures.

[0003] The existing guiding plates for minimally invasive cranial surgery usually include a face mask and a guiding channel, and a guiding needle passes through the guiding channel. The face mask and the guiding channel are made by 3D printing in one piece. When making this guiding plate, since the positions where the guiding plate penetrates into the skull and the face shapes of each patient are different, the guiding plate is usually a disposable product.

[0004] In the prior art, the guiding plate is made of plastic and will deform after sterilization, which cannot ensure the safety and accuracy of the surgical area. To solve the problem of deformation of the guiding plate, it is made of metal. Although the guiding plate made of metal will not deform after sterilization, the manufacturing cost is relatively high. Summary of the Invention

[0005] The purpose of the present application is to provide a guiding device and a preparation method for minimally invasive cranial surgery, aiming to reduce the manufacturing cost of the guiding plate and ensure good accuracy after high-temperature sterilization.

The personalized guiding member is provided with a guiding channel for guiding the implantation of a medical device through, which is established based on the pre-operative planned implantation path. The personalized guiding member is provided with a fourth connecting portion for detachably connecting with the third connecting portion. After the fourth connecting portion is connected to the third connecting portion, the guiding channel is located on the pre-operative planned implantation path.

[0011] In an exemplary embodiment of the present application, the first connecting portion is set as a standardized connecting structure.

[0012] In an exemplary embodiment of the present application, a first assembly hole is formed at the top of the personalized customization member, and a first connecting portion is formed at the periphery of the first assembly hole;

[0013] The standardized connecting member is set as an upwardly arched annular structure. A second connecting portion is formed at the bottom periphery of the standardized connecting member, and a second assembly hole is formed at the top. A third connecting portion is formed at the periphery of the second assembly hole;

[0014] A fourth connecting portion is formed at the periphery of the personalized guiding member, and the guiding channel is established on the upper surface of the personalized guiding member.

[0015] In an exemplary embodiment of the present application, the first connecting portion includes a first magnetic attraction block, the second connecting portion includes a second magnetic attraction block, and the first magnetic attraction block is magnetically connected to the second magnetic attraction block.

[0016] In an exemplary embodiment of the present application, the guiding plate for minimally invasive surgery can be used in cooperation with a surgical drape. When in use, the surgical drape is located between the first connecting portion and the second connecting portion to isolate the standardized connecting member and the personalized customization member.

[0017] In an exemplary embodiment of the present application, a plurality of first assembly holes are formed at the top of the personalized customization member, and the standardized connecting member is suitable for connecting with any one of the first assembly holes; and / or,

[0018] A plurality of second assembly holes are formed at the top of the standardized connecting member, and the personalized guiding member is suitable for connecting with any one of the second assembly holes.

[0019] In an exemplary embodiment of the present application, the guiding channel is set as a guiding tube, and the guiding tube is an integral structure or fixedly connected with the personalized guiding member.

[0020] In an exemplary embodiment of the present application, both the standardized connecting member and the personalized guiding member are made of metal materials; the personalized customization member is made of plastic material.

[0021] In an exemplary embodiment of the present application, both the personalized guiding member and the personalized customization member are made by 3D printing.

[0022] According to a second aspect of the present application, there is provided a method for preparing a guiding plate for minimally invasive surgery, characterized by comprising the following steps:

[0023] Manufacture a personalized customization member based on the three-dimensional data of the target part of the patient;

[0024] Prepare a personalized guiding member with a guiding channel based on the implantation path planned before the operation;

[0025] Connect the standardized connecting member and the personalized customization member through a first connecting portion and a second connecting portion;

[0026] Connect the personalized guiding member and the standardized connecting member through a third connecting portion and a fourth connecting portion.

[0027] The exemplary embodiments of the present application may have some or all of the following beneficial effects:

[0028] 1. In a guiding plate for minimally invasive surgery provided by the exemplary embodiment of the present application, a personalized customization member suitable for the patient to wear is formulated through the three-dimensional data of the patient, and a standardized connecting member is formulated according to the surgical requirements. It can be understood that the standardized connecting member can be widely applicable to surgical requirements. According to the lesion or target, combined with medical images, the optimal implantation path is set, and then a personalized guiding member with a guiding channel is formulated according to the implantation path. The standardized connecting member is fixedly connected to the first connecting portion of the personalized customization member through the second connecting portion; the standardized connecting member is fixedly connected to the fourth connecting portion of the personalized guiding member through the third connecting portion; the personalized customization member is worn on the target part of the patient, and through the connection of the standardized connecting member, the guiding channel on the personalized guiding member can be accurately located on the implantation path. Since the personalized customization member is installed on the target part of the patient and plays a fixing role with the patient during the operation and is far away from the surgical area, this part does not need to be sterilized at high temperature, and thus can be made of materials with lower costs; while for the standardized connecting member and the customized guiding member located in the surgical operation area, it is necessary to maintain a sterile state, so they are made of materials that are not easily deformed under high-temperature sterilization. During the operation, first, the standardized connecting member and the personalized guiding member are sterilized at high temperature, and then they are connected to the personalized customization member, and then they can be worn on the patient. Therefore, the guiding plate is made into a split structure, so that the personalized customization member can be made of materials with lower costs, and the standardized connecting member and the personalized guiding member are made of materials that are not easily deformed under high-temperature sterilization. Through the above structure, while reducing the manufacturing cost of the guiding plate, it is ensured that the guiding plate is not easily deformed after high-temperature sterilization, and thus the guiding plate has good accuracy during the operation;

[0029] 2. In a guiding plate for minimally invasive surgery provided by the exemplary embodiment of the present application, by setting the first connecting portion as a standardized connecting structure, a standardized connecting fit is formed between the first connecting portion and the second connecting portion, ensuring that when the personalized customization part changes according to the three-dimensional data shape of the patient, the structure of the first connecting portion does not change. Therefore, the standardized connecting piece can be adapted to personalized customization parts of any shape, enabling the standardized connecting piece to be reused multiple times, thereby further reducing the manufacturing cost of the guiding plate.

[0039] As Figure 1 shown, in an embodiment of the present application, a guiding plate for minimally invasive surgery is provided, which is characterized by comprising:

[0040] A personalized customization part 1, customized based on the three-dimensional data of the patient, the personalized customization part 1 is adapted to be fitted and worn on the target part of the patient, and a first connecting part 11 is arranged on the personalized customization part 1;

[0041] A standardized connecting part 2, made of a material that is not easily deformed under high-temperature sterilization, the standardized connecting part 2 is provided with a second connecting part 21 for forming a detachable connection with the first connecting part 11, and a third connecting part 22 is arranged on the personalized connecting part;

[0042] A personalized guiding part 3, made of a material that is not easily deformed under high-temperature sterilization, the personalized guiding part 3 is provided with a guiding channel for guiding the implantation of medical devices through based on the implantation path established by preoperative planning, and the personalized guiding part 3 is provided with a fourth connecting part 31 for forming a detachable connection with the third connecting part 22. After the fourth connecting part 31 is connected to the third connecting part 22, the guiding channel is located on the implantation path established by preoperative planning.

[0043] In an embodiment of the present application, the standardized connecting part 2 and the personalized guiding part 3 not only withstand high-temperature sterilization, but also are not easily deformed at high temperatures, ensuring the stability and reliability of the guiding part. In the medical field, high-temperature sterilization is a widely used disinfection method. Specifically, in terms of operation, either high-temperature steam sterilization (i.e., moist heat sterilization) or dry heat sterilization can be used, both of which can effectively kill bacteria and viruses, ensure the aseptic state of surgical instruments, and thus safeguard the safety and health of patients.

[0044] In an embodiment of the present application, as an efficient sterilization method, the principle of high-temperature steam sterilization lies in using saturated steam under high pressure to denature the proteins and nucleic acids in microorganisms, thereby completely eliminating various microorganisms. Conventional sterilization conditions include maintaining for 15 minutes at 121 °C, or extending to 30 minutes, and maintaining at 116 °C for 40 minutes. However, these conditions are only examples, and the specific temperature and time used need to be adjusted according to the material and structural characteristics of the guide member to ensure the sterilization effect while avoiding unnecessary damage to the standardized connector 2 and the personalized guide member 3. Of course, the sterilization parameters mentioned above are not fixed, and should be flexibly adjusted according to the specific situation during actual operation to achieve the best sterilization effect.

[0045] In an embodiment of the present application, dry heat sterilization can be used as another reliable sterilization method. Its mechanism lies in using the oxidation effect of high-temperature dry hot air to effectively destroy the cell structure of microorganisms, thereby achieving complete microbial killing and pyrogen elimination. Conventional dry heat sterilization conditions include maintaining for more than 120 minutes at 160 - 170 °C, or maintaining at 170 - 180 °C for more than 60 minutes, and performing treatment at 250 °C for more than 45 minutes. However, these conditions are only general guidelines, and the specific temperature and time used need to be carefully considered according to the material, structure, and sterilization requirements of the guide member to ensure the sterilization effect while taking into account the integrity and functionality of the guide member. Of course, the sterilization parameters mentioned above are not immutable, and should be flexibly adjusted according to the specific situation during actual operation to achieve a safe and effective sterilization effect.

[0046] In an embodiment of the present application, since the personalized customization part 1 is located at the target site of the patient and is far from the surgical area, there is no need for high-temperature sterilization. Therefore, the personalized customization part 1 does not need to be made of a material that is not easily deformed under high-temperature sterilization; thus, it does not need to withstand high-temperature sterilization treatment, thereby avoiding the dependence on its high-cost, high-temperature-resistant materials. In contrast, the standardized connector 2 and the personalized guide member 3, as key components in the surgical area, must undergo strict high-temperature sterilization to ensure a sterile environment. Therefore, the material selection of the standardized connector 2 and the personalized guide member 3 needs to have the characteristic of maintaining a stable form at high temperatures. In the present application, the guide plate is made into a split structure, so that the personalized customization part 1 does not need to be subjected to high-temperature sterilization, and thus allows the use of more economical materials. The standardized connector 2 and the personalized guide member 3 are made of high-quality materials that are resistant to high temperatures and do not deform, ensuring the safety and accuracy of the surgical area during the sterilization process. Through the above structure, not only is the production cost of the guide plate significantly reduced, but also, by ensuring the stability and sterility of the key surgical components, the safety and accuracy during the surgical process are guaranteed, achieving a dual optimization of cost-effectiveness and medical safety.

[0047] In this specific embodiment, taking a cranial surgery as an example, the target site is precisely defined as the facial feature area of the patient. The personalized customization part 1 is tailored according to the three-dimensional scan data of the patient's face, ensuring that it can accurately fit and be comfortably fixed on the patient's face, providing high-precision positioning and guiding functions for the surgery. In the surgical preparation stage, the personalized customization part 1 is first worn on the patient's face, and the standardized connecting part 2 is accurately docked with the first connecting part 11 of the personalized customization part 1 through its second connecting part 21 to achieve a stable connection between the two. Subsequently, the personalized guiding part 3 is connected to the third connecting part 22 of the standardized connecting part 2 through the fourth connecting part 31 to ensure the relative fixation between the personalized guiding part 3 and the standardized connecting part 2. At this time, the guiding channel is precisely aligned with the predetermined implantation path, providing precise guidance for the surgical operation. Of course, the above is only an exemplary illustration, and the target site is not limited to the face, but can also be other parts of the patient's body. When the target site changes, the structure of the personalized customization part 1 will also be adjusted accordingly to adapt to the specific characteristics of the patient's target site, ensuring accurate positioning and stable fixation in different surgical scenarios.

[0048] Through the above content, the personalized customization part 1 can be widely applied to various surgical scenarios. Whether it is cranial surgery, joint surgery or surgery on other parts, it can be personalized according to the specific needs of the patient, providing a strong guarantee for the accuracy and safety of the surgery. By precisely matching the three-dimensional data of the patient's target site, the connecting plate not only improves the accuracy of the surgery, but also reduces the surgical risk, bringing a safer and more efficient surgical experience to the patient.

[0049] In the embodiment of the present application, the first connecting part 11 of the standardized connecting part 2 is set as a standardized connection structure, ensuring a standardized and seamless docking connection mechanism between it and the second connecting part 21 of the personalized customization part 1. Its advantage is that even if the shape of the personalized customization part 1 is adjusted according to the unique three-dimensional data of the patient, the structure of the first connecting part 11 remains unchanged, thus achieving the compatibility between the standardized connecting part 2 and the personalized customization part 1 of any shape. It ensures the universality and reusability of the standardized connecting part 2, thereby further reducing the overall manufacturing cost of the guiding plate.

[0050] In the embodiment of the present application, the personalized customization part 1 is worn around the patient's face. A first assembly hole is formed at the top of the personalized customization part 1, and a standardized first connection part 11 is formed at the periphery of the first assembly hole; the standardized connection part 2 is set as an upwardly arched annular structure to be suitable for wearing on the patient's head. A standardized second connection part 21 is formed at the bottom periphery of the standardized connection part 2, and the first connection part 11 and the second connection part 21 are adapted to each other; a second assembly hole is formed at the top of the standardized connection part 2, and a standardized third connection part 22 is formed at the periphery of the second assembly hole. A standardized fourth connection part 31 is formed at the periphery of the personalized guiding part 3, and the third connection part 22 of the standardized connection part 2 is adapted to the fourth connection part 31 of the personalized guiding part 3. The upper surface of each personalized guiding part 3 can be adapted to plan several different implantation paths. Medical staff can establish a guiding channel matching the implantation path on the upper surface of the personalized guiding part 3 according to the preoperatively planned implantation path.

[0051] As a preferred implementation scheme in the embodiment of the present application, the first connection part 11 includes a first magnetic block, and the second connection part 21 includes a second magnetic block, and the two are quickly and accurately connected through magnetic force (not shown in the figure). This magnetic connection mechanism not only greatly simplifies the installation and disassembly process between the personalized customization part 1 and the standardized connection part 2, but also ensures the high stability and reliability of the two in the connected state. It is worth mentioning that the structural design of the first connection part 11 and the second connection part 21 is not limited to the magnetic attraction method.

[0052] In the further optimization of the present application, in order to ensure the aseptic environment in the surgical area and effectively isolate the aseptic area after high-temperature sterilization in the surgical area from the contaminated area outside, the guide plate can be used in cooperation with the surgical drape to build a strict aseptic barrier.

[0053] During specific implementation, the surgical drape is placed between the first connection part 11 and the second connection part 21 to form an isolation layer, separating the standardized connection part 2 from the personalized customization part 1, thereby maintaining the integrity of the aseptic environment during the surgical process. More specifically, in the embodiment of the present application, the surgical drape is accurately positioned between the first magnetic block and the second magnetic block, and with the adsorption force of the magnetic connection, the surgical drape is firmly fixed, ensuring the effectiveness of aseptic isolation.

[0054] In the embodiment of the present application, several surgical operation areas with different positions can be divided in the surgical area. Medical staff can select a suitable surgical operation area according to the lesion or target and combined with medical images before the operation, and place the personalized guiding part 3 in the surgical operation area.

[0055] In one implementation of the embodiments of the present application, a plurality of first assembly holes are provided at the top of the personalized customization part 1, and the standardized connecting part 2 is adapted to be connected to any one of the first assembly holes. Further, the second connecting part 21 on the standardized connecting part 2 can be connected to the first connecting part 11 in any one of the first assembly holes. This means that the standardized connecting part 2 can be accurately docked with the first connecting parts 11 at different positions according to actual needs. Therefore, by adjusting the connection between the standardized connecting part 2 and the first connecting parts 11 at different positions, the position of the standardized connecting part 2 can be flexibly changed, thereby driving the position adjustment of the personalized guiding part 3, ensuring that the personalized guiding part 3 can be accurately positioned within the required surgical operation area, and providing more personalized and accurate guiding support for surgical operations.

[0056] In another implementation of the embodiments of the present application, a plurality of first assembly holes are provided at the top of the personalized customization part 1, and the standardized connecting part 2 is adapted to be connected to any one of the first assembly holes; a plurality of second assembly holes are provided at the top of the standardized connecting part 2, and the personalized guiding part 3 is adapted to be connected to any one of the second assembly holes. Further, the second connecting part 21 on the standardized connecting part 2 can be connected to the first connecting part 11 in any one of the first assembly holes; the fourth connecting part 31 on the personalized guiding part 3 can be connected to the third connecting part 22 in any second assembly hole. Therefore, when splicing the guiding plate, not only can the position of the standardized connecting part 2 be changed by adjusting the connection between the standardized connecting part 2 and the first connecting parts 11 at different positions, but also the relative position between the personalized guiding part 3 and the standardized connecting part 2 can be flexibly adjusted by connecting the personalized guiding part 3 to the third connecting parts 22 at different positions. Through the above structure, the applicable range of the personalized guiding part 3 is greatly expanded, enabling it to adapt to more surgical operation areas at different positions, thus significantly improving the applicability and flexibility of the guiding plate in complex surgical operations.

[0057] As the optimal solution in the embodiments of the present application, one first assembly hole is provided at the top of the personalized customization part 1, and this first assembly hole covers the entire top of the personalized customization part 1. Therefore, it can be understood that the first connecting part 11 covers the entire top of the personalized customization part 1; thus, the personalized customization part 1 and the standardized connecting part 2 achieve the maximum degree of connection. This comprehensive coverage connection method greatly enhances the stability of the standardized connecting part 2 and ensures the safety and reliability during the surgical operation process.

[0058] Meanwhile, a plurality of second assembly holes are provided at the top of the standardized connector 2, and each second assembly hole corresponds to a specific surgical operation area. The personalized guide 3 is adapted to be connected to any one of the second assembly holes. Through the combination of the above structures, it not only ensures that the guide plate can adapt to surgical operation areas at more different positions, but also guarantees the good stability of the guide plate in a complex surgical environment, providing more accurate, safe and efficient guiding support for surgical operations.

[0059] As Figure 1 and Figure 2 shown, in the implementation of the present application, the guiding channel is set as the guiding tube 32, and the guiding tube 32 and the personalized guide 3 are of an integral structure or fixedly connected. Of course, this is not restrictive. The guiding channel can also adopt the structure of two or more guiding rings to adapt to different surgical requirements. It should be noted that when the guiding channel adopts a plurality of guiding rings, all the guiding rings need to be accurately arranged on the implantation path to ensure the accuracy of surgical operations.

[0060] In order to effectively control the manufacturing cost of the guide plate, the personalized customization part 1 is preferably made of plastic material. This choice optimizes the cost while ensuring the basic functions. However, in order to ensure the good accuracy and safety of the guide plate during the surgical process, the materials of the standardized connector 2 and the personalized guide 3 need to adopt metal materials that are not easily deformed under high-temperature sterilization conditions. This kind of material can not only withstand the high-temperature sterilization treatment in the surgical environment, but also maintain the structural stability and strength, ensuring the accuracy and safety of surgical operations. Of course, this is not restrictive.

[0061] The following is a preparation method for a guide plate for minimally invasive surgery, aiming to provide accurate guiding and positioning for surgical operations:

[0062] In the embodiment of the present application, both the personalized guide 3 and the personalized customization part 1 are made by 3D printing.

[0063] S1. Make the personalized customization part 1 based on the three-dimensional data of the patient's target part;

[0064] S2. Prepare the personalized guide 3 with a guiding channel based on the pre-operative planned implantation path;

[0065] S3. Connect the standardized connector 2 and the personalized customization part 1 through the first connection part 11 and the second connection part 21;

[0066] S4. Connect the personalized guide 3 and the standardized connector 2 through the third connection part 22.

[0067] In the specific implementation preparation method of the present application, in S1 and S2, the personalized customization part 1 is made of plastic by 3D printing, which not only realizes the efficient production of the personalized customization part 1, but also ensures its good accuracy. At the same time, the personalized guiding part 3 is made of metal powder, and the precise manufacturing of complex structures is also realized by means of 3D printing technology. During the production of the personalized guiding part 3, according to the lesion or target, combined with medical images, the optimal implantation path is set. The determination of the optimal implantation path directly guides the position design of the guiding channel. Therefore, during the 3D printing process, the guiding channel and the personalized guiding part 3 are printed into an integral structure, which not only facilitates its own processing and production, but also ensures the accuracy of its own guidance.

[0068] In the S3 implementation step of the present application, when the personalized customization part 1 is accurately worn on the target part, the primary task is to attach a surgical drape to the first connecting part 11 of the personalized customization part 1. This operation aims to provide a sterile environment for subsequent surgical operations. Subsequently, the standardized connecting part 2 is tightly connected and fixed to the first connecting part 11 of the personalized customization part 1 through its second connecting part 21, and at the same time can clamp the surgical drape between the two, ensuring good stability of the surgical drape during the operation. This structure not only effectively isolates the contaminated area and the sterile area, but also creates a safe and sterile environment for surgical operations, greatly reducing the risk of surgical infection.

[0069] Finally, according to the specific position of the lesion or target, combined with advanced medical imaging technology, the optimal surgical operation area is selected. This area, that is, the third connecting part 22 at the optimal position, will be used as the connection position between the personalized guiding part 3 and the standardized connecting part 2. The precise connection of the personalized guiding part 3 to the selected third connecting part 22 not only ensures the accuracy of the surgical operation, but also provides good stability for the operation.

[0070] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the embodiments of the present application. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field not claimed in the present application. The specification and examples are only to be considered as exemplary, and the true scope and spirit of the present application are pointed out by the appended claims.
