Description

Technical Field

[0001] The present invention relates to the field of intelligent systems, and in particular to a brain tumor needle line marking system and a method for using the same Background Art

[0002] With the continuous advancement of medical technology, the safety and accuracy of brain surgery have received increasing attention. In traditional brain surgery, doctors usually rely on preoperative imaging data and intraoperative navigation systems to mark tumor boundaries. However, due to possible brain drift during surgery (i.e., the displacement of brain tissue during surgery), these preliminary markings often lose accuracy, thereby increasing the risk and complexity of the operation. Therefore, developing a method that can accurately and durably mark tumor boundaries before surgery to prevent the impact of intraoperative brain drift on surgical accuracy has become an urgent problem to be solved in the current field of brain surgery.

[0003] Brain surgery is a highly complex and risky medical procedure. During the operation, doctors need to accurately identify and remove tumor tissue while avoiding damage to the surrounding normal brain tissue. To achieve this goal, doctors usually use imaging technologies such as MRI (magnetic resonance imaging) and CT (computed tomography) to obtain brain images of patients before surgery to identify and locate tumor boundaries. However, due to the complexity of brain tissue and possible brain drift during surgery, these preliminary markings are often difficult to maintain accuracy.

[0004] Although the existing brain surgery navigation system can improve the accuracy of surgery to a certain extent, it is still limited by factors such as brain drift. Therefore, developing a method that can accurately and permanently mark the tumor boundary before surgery is of great significance to improving the safety and success rate of brain surgery.

[0005] In order to solve the above problems, the applicant proposes a brain tumor needle line marking system and a method of using the same. Summary of the invention

[0006] The object of the present invention is to provide a brain tumor needle line marking system and a method of using the same to solve the problems in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solution: a brain tumor needle line marking system, comprising the following parts:

[0008] A navigation device, which uses image recognition and positioning technology to receive the patient's brain imaging data and conduct in-depth analysis to accurately control the positioning and direction of the needle and thread;

[0009] sets of tiny needles and threads, carefully crafted from biodegradable materials, used to clearly mark tumor boundaries during brain surgery;

[0010] The control system is responsible for receiving brain image data and transmitting this data to the navigation device, while also controlling the movement of the navigation device to ensure accurate implantation of the needle and thread.

[0011] Optionally, the navigation device further comprises the following functional modules:

[0012] The image matching module is responsible for matching the preoperative brain image with the real-time intraoperative image to correct errors caused by brain drift;

[0013] The path planning module plans the needle and thread implantation path based on the specific boundary information of the tumor;

[0014] The precise control module guides the needle to be implanted precisely into the tumor boundary along the predetermined route according to the path set by the path planning module.

[0015] The needle and thread combination also includes the following elements:

[0016] The needle body has both rigidity and toughness to ensure that it is not easily broken when implanted into brain tissue;

[0017] The thread, also made of biodegradable material, is tightly connected to the needle body, together forming a durable physical mark at the tumor boundary.

[0018] The control system also includes the following components:

[0019] A data receiving module, used for receiving and storing brain image data;

[0020] The navigation operation module is closely connected with the navigation device and is responsible for controlling its actions;

[0021] The monitoring and alarm module monitors the working status of the navigation device and the needle and thread combination in real time, and immediately issues an alarm if any abnormality is found.

[0022] A method for using a brain tumor needle line marking system comprises the following steps:

[0023] S1. Preoperative preparation: Obtain the patient's brain image and clarify the tumor boundary;

[0024] S2, data entry: input brain image data into the navigation device;

[0025] S3, Needle and thread implantation: The navigation device guides the needle and thread to be accurately implanted into the tumor boundary according to the preset path;

[0026] S4. Intraoperative application: During the operation, the real-time images provided by the navigation device are used to observe the position and shape of the needle and line markings, providing doctors with accurate tumor boundary references.

[0027] The navigation device in S3 also uses an image matching module to match the preoperative and intraoperative brain images to eliminate errors caused by brain drift.

[0028] In S4, the doctor adjusts the implantation position and path of the needle and thread according to the actual needs of the operation to ensure the accuracy of the marking.

[0029] Beneficial effects:

[0030] Compared with the prior art, the brain tumor needle line marking system of the present invention exhibits significant advantages and positive effects.

[0031] First, the system uses the precise control of the navigation device to precisely sew the biodegradable needle into the tumor boundary, providing doctors with clear and accurate tumor boundary information during surgery. This physical marking method effectively reduces surgical errors caused by factors such as brain drift, and significantly improves the accuracy and safety of surgery.

[0032] Secondly, the needle and thread materials used in this system are biodegradable and can gradually degrade and be naturally absorbed by the human body within a certain period of time after the operation. There is no need for a second operation to remove them, thereby reducing the risk of postoperative complications and alleviating the patient's pain and burden.

[0033] In addition, the implementation of the present invention also improves the success rate of brain surgery. Due to the reduction of surgical errors and the improvement of the accuracy of tumor boundary identification, doctors can more accurately determine the location and range of the tumor, thereby formulating a more reasonable surgical plan, improving the efficiency and success rate of the operation.

[0034] In summary, the brain tumor needle line marking system of the present invention has significant beneficial effects, provides a new, more reliable and safe auxiliary means for brain surgery, and has important clinical application value. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 2 It is a schematic diagram of excising human tissue after using the embodiment of the present invention. DETAILED DESCRIPTION

[0037] The following describes the preferred embodiments of the present invention with reference to the drawings in the specification, so that the technical content is clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0038] Example 1

[0039] In view of the problems existing in the prior art, the present invention proposes a brain tumor needle and thread marking system. The system includes a navigation device and a plurality of fine needle and thread combinations, and uses precise control to sew the biodegradable needle and thread precisely into the tumor boundary to form a durable and reliable physical mark.

[0040] The navigation device is one of the core components of the present invention. It uses advanced image recognition and positioning technology to accurately identify and locate the tumor boundary in the brain image. During the operation, the navigation device can track the movement of brain tissue in real time and adjust the placement of needles and threads as needed to ensure the accuracy of marking.

[0041] The needle and thread combination is a physical medium used to mark the tumor boundary in the present invention. The needle and thread are made of biodegradable materials and have excellent biocompatibility and degradation performance. During the operation, the navigation device accurately sews the needle and thread into the tumor boundary along a preset path. Since the needle and thread have a durable physical form and biodegradability, they can provide doctors with accurate tumor boundary information during the operation and reduce the risk of postoperative complications.

[0042] Before surgery, doctors need to use imaging technologies such as MRI or CT to obtain images of the patient's brain. Through image analysis software, doctors can identify and locate the tumor boundary and determine the placement and path of the needle. This step is the basis for ensuring the success of the operation, so it requires doctors to have rich professional knowledge and experience.

[0043] The brain images and tumor boundary information acquired before surgery are input into the navigation device. The navigation device uses image recognition and positioning technology to accurately register and position the brain images, thereby ensuring accurate placement of the needle and thread.

[0044] During the operation, the navigation device controls the needle and thread to accurately sew into the tumor boundary along the preset path. The needle and thread placement process is completed automatically without the need for manual operation by the doctor. This step ensures high accuracy and repeatability of needle and thread marking, while reducing operation time and risks.

[0045] In order to ensure the accuracy and reliability of needle and thread marking, the navigation device needs to consider multiple factors when placing the needle and thread, such as the movement of brain tissue, the length and diameter of the needle and thread, etc. By tracking the movement of brain tissue in real time and adjusting the placement of the needle and thread as needed, the navigation device can ensure the durability and accuracy of the needle and thread marking during the operation.

[0046] During surgery, doctors can use the real-time image information provided by the navigation device to observe the position and shape of the needle and thread markers. These physical markers provide doctors with accurate tumor boundary information, helping doctors avoid damaging surrounding normal brain tissue when removing tumor tissue. At the same time, because the needle and thread have a persistent physical form and biodegradability, they can continue to provide doctors with accurate tumor boundary information during surgery.

[0047] Through the combination of navigation devices and biodegradable needles and threads, the present invention can achieve accurate marking of tumor boundaries. During surgery, doctors can use these physical markers as references to accurately remove tumor tissue and avoid damaging surrounding normal brain tissue. This feature significantly improves the accuracy and safety of surgery.

[0048] Since the needle-thread marking system provided by the present invention can significantly improve the accuracy of surgery, it can greatly reduce surgical risks. In traditional brain surgery, marking errors caused by factors such as brain drift often increase the risk and complexity of surgery. The present invention achieves a durable and reliable marking of tumor boundaries through a combination of a navigation device and a biodegradable needle-thread, thereby effectively avoiding surgical risks caused by marking errors.

[0049] In addition, the needle and thread are made of biodegradable materials and have excellent biocompatibility. After the operation, the needle and thread can gradually degrade and be absorbed by the human body, without the need for a second operation to remove them. This feature further reduces the risk of surgery and alleviates the patient's pain and postoperative recovery burden.

[0050] The brain tumor needle-line marking system of the present invention not only improves the accuracy and safety of surgery, but also significantly improves the success rate of surgery. By accurately marking the tumor boundary, doctors can more accurately remove tumor tissue, thereby improving the surgical resection rate and treatment effect. At the same time, since the surgical risks and complications are reduced, the patient's postoperative recovery is also smoother, further improving the success rate of surgery.

[0051] The needle and thread are made of biodegradable materials with excellent biocompatibility and degradation performance. After the operation, the needle and thread can gradually degrade and be absorbed by the human body, thus avoiding the risk of postoperative complications caused by foreign body residue. This feature not only reduces the patient's pain and postoperative recovery burden, but also improves the overall effect of the operation and the patient's quality of life.

[0052] The brain tumor needle-line marking system of the present invention is mainly composed of a navigation device, a needle-line combination, a control system and the like.

[0053] The navigation device is one of the core components of the system, responsible for achieving accurate registration and positioning of brain images, as well as precise placement of needles and threads. The device uses advanced image recognition and positioning technology to track the movement of brain tissue in real time and adjust the placement of needles and threads as needed. At the same time, the navigation device also has the characteristics of high precision and repeatability, which can ensure the accuracy and reliability of needle and thread marking.

[0054] The needle and thread combination is the physical medium used to mark the tumor boundary in the system. The needle and thread are made of biodegradable materials with excellent biocompatibility and degradation performance. During the operation, the navigation device accurately sews the needle and thread into the tumor boundary along the preset path. Parameters such as the length and diameter of the needle and thread can be adjusted according to actual needs to meet the needs of different surgical scenarios.

[0055] The control system is one of the key parts of the system, responsible for achieving the coordinated work of the navigation device and the needle and thread combination. The system uses advanced control algorithms and technologies to monitor and control the movement status of the navigation device and the placement and path of the needle and thread in real time. At the same time, the control system also has fault detection and alarm functions, which can detect and handle abnormal situations in a timely manner to ensure the safe and stable operation of the system.

[0056] Before surgery, doctors use imaging technologies such as MRI or CT to obtain brain images of patients, and use image analysis software to identify and locate the tumor boundary. Then, the brain image and tumor boundary information are input into the navigation device. The navigation device uses image recognition and positioning technology to accurately register and locate the brain image, and determine the placement and path of the needle and thread.

[0057] During the operation, the navigation device controls the needle and thread to sew accurately into the tumor boundary along the preset path. The needle and thread placement process is completed automatically without the need for manual operation by the doctor. At the same time, the navigation device can track the movement of brain tissue in real time and adjust the placement of the needle and thread as needed to ensure the accuracy of the marking.

[0058] During and after surgery, doctors can use the real-time image information provided by the navigation device to observe the position and shape of the needle and thread markers. These physical markers provide doctors with accurate tumor boundary information, helping doctors avoid damaging surrounding normal brain tissue when removing tumor tissue. At the same time, because the needle and thread have a persistent physical form and biodegradability, they can continue to provide doctors with accurate tumor boundary information during surgery.

[0059] In order to verify the effectiveness and reliability of the brain tumor needle line marking system of the present invention, we conducted a large number of experimental verifications and clinical application studies.

[0060] During the experimental verification phase, we used simulated surgery and animal experiments to comprehensively evaluate the performance of the system. Through simulated surgery, we verified the accuracy and repeatability of the navigation device; through animal experiments, we evaluated the biocompatibility and degradation performance of the needle-thread combination and the application effect of the system in actual surgery. The experimental results show that the system can accurately mark the tumor boundary and provide reliable reference information for doctors during surgery.

[0061] During the clinical application phase, we selected several hospitals for collaborative research. Through actual application and observation of brain surgeries on patients, we evaluated the effectiveness and safety of the system. Clinical results show that this system can significantly improve the accuracy and safety of surgery, reduce surgical risks and complications, and improve the success rate of surgery and the quality of life of patients. At the same time, patients' acceptance and satisfaction with this system are also high.

[0062] In summary, the brain tumor needle line marking system of the present invention has significant technical advantages and clinical application value.
