Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to a guide plate for minimally invasive skull surgery and a preparation method thereof. Background Art

[0002] Minimally invasive surgical guides are medical tools used to improve surgical precision and safety. Minimally invasive surgery has attracted widespread attention due to its small incision, quick recovery, and less pain. With the development of medical technology, more and more surgeries can be performed in a minimally invasive manner, which places higher demands on surgical instruments and techniques. In minimally invasive surgery, in order to ensure the accuracy of the surgery, doctors need to perform operations at specific anatomical locations. Guides provide visual guidance to help surgeons locate and plan surgical paths during surgery, reducing the risk of errors and complications.

[0003] With the development of three-dimensional imaging technology (such as CT, MRI, etc.), we can better understand the patient's anatomical structure. At the same time, the application of 3D printing technology makes it possible to customize the guide plate according to the individual characteristics of the patient, further enhancing the personalization and precision of the surgery.

[0004] Prior art, such as Chinese patent document CN221129999U, discloses an improved 3D printed puncture guide, including a guide body, a positioning support and a puncture base, which are 3D printed according to the patient's CT data for the lesion. When in use, the puncture guide is positioned and placed by fitting it to the patient's target part. However, in actual use, the applicant found that the 3D printed puncture guide needs to be sterilized at high temperature before minimally invasive surgery, but the 3D printed puncture guide usually made of plastic material is easy to deform at high temperature, and the deformed puncture guide cannot fit the patient's wearing part (such as the patient's face in minimally invasive skull surgery) during actual surgery, resulting in inaccurate positioning of the puncture guide, and then inaccurate puncture point and puncture path, resulting in reduced accuracy and safety of the surgery. Summary of the invention

[0005] The purpose of the present application is to provide a minimally invasive surgical guide plate and a preparation method, aiming to solve the problem of low surgical accuracy and safety.

[0006] Additional aspects and advantages of the present application will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the present application.

[0007] According to a first aspect of the present application, a minimally invasive surgery guide plate is provided, comprising:

[0008] A customized connection plate, customized based on the patient's three-dimensional data, the customized connection plate is suitable for being worn on the patient's target part, and a first connection portion is reserved on the customized connection plate;

[0009] The guide member is made of a material that is not easily deformed under high-temperature sterilization. The guide member establishes a guide channel for guiding the implanted medical device to pass through. The guide member is provided with a second connection part for forming a detachable fixed connection with the first connection part; after the first connection part is connected to the second connection part, the guide channel is located on the implantation path planned before the operation.

[0010] In an exemplary embodiment of the present application, the first connecting portion includes a plurality of fixing points arranged on the customized connecting plate, and the second connecting portion can form a detachable connection with any of the fixing points.

[0013] In an exemplary embodiment of the present application, the first connecting part also includes a first magnetic block arranged at the plurality of fixed points, and the second connecting part includes a second magnetic block arranged at the far ends of the first support member and the second support member, and the first magnetic block and the second magnetic block can be magnetically connected.

[0014] In an exemplary embodiment of the present application, the minimally invasive surgical guide plate can be used in conjunction with a surgical towel. When in use, the surgical towel is located between the customized connecting plate and the guide member to isolate the two.

[0015] In an exemplary embodiment of the present application, the customized connecting plate is made of plastic and is manufactured by 3D printing.

[0017] In an exemplary embodiment of the present application, the target site is a skull, the customized connection plate is customized based on the facial features of the skull, and the customized connection plate is suitable for fitting and wearing on the face of the patient.

[0018] According to a second aspect of the present application, a method for preparing a minimally invasive surgical guide plate comprises the following steps:

[0019] A customized connection plate with a first connection portion reserved is produced based on the three-dimensional data of the target part of the patient;

[0020] The specific position of the first connecting portion on the customized connecting plate is determined based on the implantation path planned before surgery and the fixed size of the guide.

[0021] The exemplary embodiments of the present application may have some or all of the following beneficial effects:

[0022] 1. In a minimally invasive surgical guide plate provided in an example embodiment of the present application, the customized connecting plate is customized based on the three-dimensional data of the patient's target part, so that the customized connecting plate can be accurately matched with the patient's target part. When facing a puncture operation, the first task is to accurately locate the puncture point, and then plan the optimal implantation path based on the lesion or target point in combination with medical imaging. The implantation path thus planned essentially defines the precise position of the guide channel during the operation, that is, the surgical instrument must pass through the guide channel to accurately reach the target position that needs to be implanted in the patient's body.

[0024] 3. Through the magnetic connection between the first magnetic block and the second magnetic block, the connection and fixation of the guide member and the customized connecting plate can be achieved.

The surgical towel forms a physical isolation barrier, which divides the sterile area in the operating area from the sterile area outside, providing a solid guarantee for the sterile control of the operating environment.

[0033] like Figure 1 and Figure 2 As shown, in an embodiment of the present application, a minimally invasive surgery guide plate includes:

[0034] A customized connection plate 1 is customized based on the patient's three-dimensional data, and the customized connection plate 1 is suitable for fitting and wearing on the patient's target part, and a first connection portion 4 is reserved on the customized connection plate 1;

[0035] The guide member is made of a material that is not easily deformed under high-temperature sterilization. The guide member establishes a guide channel for guiding the implanted medical device to pass through. The guide member is provided with a second connecting part 5 for forming a detachable fixed connection with the first connecting part 4; after the first connecting part 4 is connected to the second connecting part 5, the guide channel is located on the implantation path planned before the operation.

[0036] In the embodiment of the present application, the setting of the customized connecting plate 1 fully considers the individual needs of patients. When facing a puncture operation, the first task is to accurately locate the puncture point, and then plan the optimal implantation path based on the lesion or target and medical imaging. The implantation path thus planned essentially defines the precise position of the guide channel during the operation, that is, the surgical instruments must follow the guide channel to pass through the target position to accurately reach the target position that needs to be implanted in the patient's body. By combining the known guide channel position and the specific size of the guide, the connection position of the first connecting part 4 and the second connecting part 5 on the customized connecting plate 1 can be accurately derived, thereby ensuring the accuracy and safety of the surgical operation.

[0037] In the embodiment of the present application, the guide piece not only withstands high temperature sterilization, but also is not easily deformed at high temperature, thus ensuring the stability and reliability of the guide piece. In the medical field, high temperature sterilization is a widely used disinfection method. In specific operations, high temperature steam sterilization (i.e., moist heat sterilization) or dry heat sterilization can be used. Both can effectively kill bacteria and viruses, ensure the sterility of surgical instruments, and thus maintain the safety and health of patients.

[0038] In the embodiments of the present application, high-temperature steam sterilization is used as an efficient sterilization method. The principle is to use saturated steam under high pressure to denature the proteins and nucleic acids in microorganisms, thereby completely eliminating all kinds of microorganisms. Conventional sterilization conditions include 121°C for 15 minutes, or extended to 30 minutes, and 116°C for 40 minutes. However, these conditions are only examples. The specific temperature and time used need to be adjusted according to the material and structural characteristics of the guide to ensure the sterilization effect while avoiding unnecessary damage to the guide. Of course, the above-mentioned sterilization parameters are not fixed. In actual operation, they should be flexibly adjusted according to the specific situation to achieve the best sterilization effect.

[0039] In the embodiments of the present application, dry heat sterilization can be used as another reliable sterilization method. Its mechanism is to use the oxidation effect of high-temperature dry hot air to effectively destroy the cell structure of microorganisms, thereby achieving thorough microbial killing and pyrogen elimination. Conventional dry heat sterilization conditions include more than 120 minutes at 160-170°C, or more than 60 minutes at 170-180°C, and more than 45 minutes at 250°C. However, these conditions are only general guidelines. The specific temperature and time used need to be carefully considered according to the material, structure and sterilization requirements of the guide to ensure the sterilization effect while taking into account the integrity and functionality of the guide. Of course, the sterilization parameters mentioned above are not fixed. In actual operation, they should be flexibly adjusted according to the specific situation to achieve a safe and effective sterilization effect.

[0040] In an embodiment of the present application, the implantation path planned before surgery is defined as the precise path for the surgical instrument to pass through. Specifically, when the surgical device is a puncture needle, the implantation path is the path for the puncture needle to penetrate precisely, ensuring the accuracy and safety of the surgical operation. However, the above description is only an exemplary description, and the scope of application of this application is far more than that. For example, the surgical instrument may also be an electrode, in which case the implantation path is converted into the penetration path of the electrode, which also follows the principle of precise planning to meet the needs of different surgical scenarios.

[0041] In the embodiment of the present application, the first connection part 4 includes a plurality of fixed points 41 provided on the customized connection plate 1. Specifically, the position of the fixed point 41 will be adjusted according to the change of the implantation path, so as to form a series of fixed points 41 adapted to the requirements of different implantation paths on the surface of the customized connection plate 1, so as to adapt to the implantation paths at different positions. The second connection part 5 can form a detachable connection with any of the fixed points 41, so that the guide member and the customized connection plate 1 can be assembled and disassembled, so that the guide member can be made into a standard part and recycled, which reduces the consumption of surgical materials and effectively controls the cost of surgery.

[0042] In the embodiments of the present application, there is no special restriction on the specific structure and number of the guide member, and the guide member can be either an integral structure or multiple independent split structures. When the guide member adopts an integral structure, the guide channel portion of the guide member can be set as a guide tube, and the internal channel of the guide tube is directly aligned with the implantation path to ensure accurate guidance of the surgical instrument. When the guide member is a plurality of split structures, the number of the split structures should be set to at least two. Thereby determining a precise implantation path.

[0043] As a specific example of when the guide member is set as a plurality of split structures, the guide member setting includes a first guide member 2 and a second guide member 3. The first guide member 2 is equipped with a first guide ring 21, and the second guide member 3 is equipped with a second guide ring 31. The inner sides of the first guide ring 21 and the second guide ring 31 should match the implanted surgical instrument. In the current embodiment, the inner cross-sections of the first guide ring 21 and the second guide ring 31 are both set to be circular to ensure smooth passage of the surgical instrument. However, this setting is not fixed. According to the requirements of the surgical instrument, the inner cross-sections of the first guide ring 21 and the second guide ring 31 can also be designed to be square, triangular or any other non-standard shapes to adapt to the special requirements of different surgical instruments.

[0044] It is worth noting that both the first guide member 2 and the second guide member 3 are recyclable standard parts, which means that the two can not only effectively save surgical costs, but also be reused in different operations to improve resource utilization. On the customized connecting plate 1, the first guide member 2 and the second guide member 3 should correspond to two fixed points 41 at different positions respectively to ensure a stable connection with the customized connecting plate 1. When the first guide member 2 and the second guide member 3 are connected to the customized connecting plate 1 through their respective fixed points 41, the first guide ring 21 and the second guide ring 31 will remain parallel, and the inner holes of the two will be located on the same straight line, together forming a guide channel to provide precise guidance for surgical instruments.

[0045] Of course, the number of guide members in a split structure is not limited to two. Depending on the surgical situation, the number of guide members can be three, four or more. But the key is that the split structures of all guide members must be parallel to each other, and the inner holes must be located in the same straight line to ensure the continuity and consistency of the guide channel and meet the high-precision requirements of surgical operations.

[0046] In the embodiment of the present application, the first guide member 2 also includes a first support member 22, which is an integral structure or fixedly connected to the first guide ring 21, thereby ensuring the stability and reliability of the structure between the first support member 22 and the first guide ring 21; the second guide member 3 also includes a second support member 32, which is an integral structure or fixedly connected to the second guide ring 31, thereby ensuring the stability and reliability of the structure between the second support member 32 and the second guide ring 31.

[0047] It is worth noting that the second connection part 5 is respectively arranged at the distal end of the first support member 22 and the distal end of the second support member 32. Specifically, the second connection part 5 is respectively fixedly connected to the end of the first support member 22 away from the first guide ring 21, and the end of the second support member 32 away from the second guide ring 31. Through the above structure, not only the stable connection between the second connection part 5 and the first support member 22 and the second support member 32 is ensured, but also the accurate positioning and stable guidance of the guide member during the operation are ensured.

[0048] In the embodiment of the present application, the first connecting part 4 also includes a first magnetic block 42 provided at a plurality of fixed points, and the second connecting part 5 includes a second magnetic block provided at the far end of the first support member 22 and the second support member 32. The number of the first magnetic block 42 and the second magnetic block are consistent with the number of the guide members, and the first magnetic block 42 and the second magnetic block can be magnetically connected. Specifically, after the customized connecting plate 1 is processed, the first magnetic block 42 is installed and fixed at the fixed point 41, and the installation method is not particularly limited. In the current embodiment, the first magnetic block 42 is installed and fixed to the customized connecting plate 1 by pasting. In other embodiments, it can also be installed by means of snap-on, plug-in, threaded connection, etc.

[0049] In the embodiment of the present application, it is ensured that a sterile environment can be maintained in the surgical area during minimally invasive surgery, while reducing the cost of surgery. Specifically, the minimally invasive surgical guide plate can be used in conjunction with a surgical towel. During use, the surgical towel is located between the customized connecting plate 1 and the guide member to isolate the two (not shown in the figure). A physical isolation barrier is formed to divide the sterile area in the surgical area from the sterile area outside, providing a solid guarantee for the sterile control of the surgical environment. Specifically, the surgical towel is located between the first magnetic block 42 and the second magnetic block. The surgical towel is firmly fixed through the magnetic adsorption force between the magnetic blocks, ensuring that no displacement occurs during the operation, providing a stable foundation for surgical operations.

[0050] Due to the presence of the surgical towel, medical staff only need to sterilize the guide, without sterilizing the customized connecting plate 1, which not only saves sterilization time, but also reduces sterilization costs. More importantly, since the customized connecting plate 1 does not need to be sterilized at high temperature, its material selection can be more flexible, such as using lower-cost materials such as plastic, further reducing the manufacturing cost of surgical equipment and bringing economic benefits to medical institutions and patients.

[0051] In the embodiment of the present application, the customized connecting plate 1 adopts 3D printing technology and uses plastic as the main material, which not only realizes the efficient production of personalized customization, but also significantly reduces the cost of surgery, bringing economic benefits to medical institutions and patients. At the same time, the guide piece is made of metal material, which has good stability and is not easy to deform during high-temperature sterilization, ensuring that the guide piece can maintain its accuracy and reliability after multiple uses and sterilization, providing solid technical support for surgical operations.

[0052] More importantly, the combination of the metal guide and the custom plastic connecting plate 1 not only achieves a balance between cost and performance, but also provides a double guarantee for the sterile environment of the surgical area. The ability of the metal guide to withstand high temperature sterilization ensures the sterile state in the surgical area, while the use of the custom plastic connecting plate 1 reduces the cost of disposable consumables. Through the structure of the two, the sterile environment during the operation is maintained and the cost of the operation is reduced.

[0053] In the embodiments of the present application, the target part takes the head as an example, and the customized connecting plate 1 fully considers the characteristics of the head to ensure that it can be accurately fitted and comfortably worn on the patient's head, providing accurate positioning and guidance for the operation. Of course, the above is only an exemplary description, and the target part is not limited to the head, but can also be other parts of the patient's body. When the target part changes, the structure of the customized connecting plate 1 will also be adjusted accordingly to adapt to the specific characteristics around the patient's target part, ensuring accurate positioning and stable fixation in different surgical scenarios.

[0054] Through the above content, the customized connection plate 1 can be widely used in a variety of surgical scenarios. Whether it is skull surgery, joint surgery or surgery on other parts, it can be customized according to the specific needs of the patient, providing a strong guarantee for the accuracy and safety of the surgery. By accurately matching the three-dimensional data of the patient's target part, the customized connection plate 1 not only improves the accuracy of the surgery, but also reduces the risk of surgery, bringing patients a safer and more efficient surgical experience.

[0055] In an embodiment of the present application, a method for preparing a minimally invasive surgery guide plate comprises the following steps:

[0056] A customized connection plate 1 with a first connection portion 4 reserved is produced based on the three-dimensional data of the target part of the patient;

[0057] The specific position of the first connecting portion 4 on the customized connecting plate 1 is determined based on the implantation path planned before surgery and the fixed size of the guide.

[0058] In the embodiment of the present application, there are detailed operation steps for the preparation and assembly of the minimally invasive surgical guide plate to ensure the accuracy and safety of the surgery. Among them, by accurately analyzing the known implantation path position and the size of the standard guide, the connection position of the first connection part 4 and the second connection part 5 on the customized connection plate 1 can be determined, which is the cornerstone of the entire preparation process.

[0059] The following are the specific steps for the preparation and assembly of minimally invasive surgical guide plates, which are designed to provide precise guidance and positioning for surgery:

[0060] S1, based on the precise position of the implantation path, determine the positioning of the first guide ring 21 and the second guide ring 31. Combined with the size information of the standard guide, the specific size of the first support member 22 and the second support member 32 is clarified. The specific positions of the two fixed points 41 on the customized connection plate 1 can be accurately derived. Plastic materials are used, and 3D printing technology is used based on the three-dimensional data of the patient's target part to directly prepare a customized connection plate 1 with preset fixed points 41 to ensure accurate matching with the patient's target part;

[0061] S2, install the two first magnetic blocks 42 on the fixed points 41 of the customized connection plate 1 respectively. The installation method can be pasting, clamping, plugging, threading, etc. to ensure the stable fixation of the first magnetic blocks 42. After the installation is completed, the customized connection plate 1 with the first magnetic blocks 42 is accurately worn on the target part of the patient, providing a stable positioning basis for subsequent surgical operations;

[0062] S3, strictly perform high-temperature sterilization on the first guide member 2 and the second guide member 3 to ensure that the surgical area is in a sterile state and provide guarantee for surgical safety;

[0063] S4, cover the target part of the patient with the surgical towel, use the magnetic adsorption force between the second magnetic block and the first magnetic block 42 to connect and fix the guide piece with the customized connecting plate 1, and clamp the surgical towel between the first magnetic block 42 and the second magnetic block. After the guide piece is installed, the inner holes of the first guide ring 21 and the second guide ring 31 form a guide channel, which is precisely aligned with the implantation path, providing a solid guarantee for the accuracy and safety of the operation.

[0064] The execution order of the above steps S1 to S4 is not fixed and can be flexibly adjusted according to actual conditions, and some steps can also be performed in parallel to optimize the overall process efficiency. For example, while the first guide member 2 and the second guide member 3 are sterilized at high temperature, the 3D printing of the customized connecting plate 1 can be started simultaneously. This parallel operation mode can not only effectively shorten the preparation time of the customized guide plate, but also improve the efficiency of the pre-operative preparation work, buy more valuable time for the surgical team, and ensure the smoothness and efficiency of the surgical process.

[0065] Those skilled in the art will easily think 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 modification, use or adaptation of the present application, which follows the general principles of the present application and includes common knowledge or customary techniques in the art that the present application does not apply for. The specification and embodiments are only regarded as exemplary, and the true scope and spirit of the present application are pointed out by the appended claims.
