Description

Technical Field

[0001] The present invention relates to the technical field of myocardial puncture, and in particular to a device, system and method for myocardial biopsy puncture. Background Art

[0002] With the development of cardiac diagnosis and treatment, myocardial biopsy is becoming more and more necessary. At present, the classification and etiology of diseases such as dilated cardiomyopathy, hypertrophic cardiomyopathy, tumor heart disease, and drug-induced heart disease rely on diagnostic tools such as echocardiography, cardiac MRI, and genetic testing, but their exact and precise causes still require myocardial biopsy.

[0003] Myocardial biopsy puncture is a surgery with complicated operation steps. Even after countless simulations and observations, many interns will still be nervous when they actually perform the operation for the first time. Nervous situations can easily lead to errors and omissions in operation steps. At this time, the chief physician's reminder will make the patient feel anxious. In addition, the camera of the puncture device is relatively fixed and difficult to adjust. As a result, during the operation, the camera may not be facing the surgical position, making it impossible to accurately capture the operation process.

[0004] Therefore, we propose a device, system and method for myocardial biopsy puncture. Summary of the invention

[0005] To this end, the present invention provides a device, system and method for myocardial biopsy puncture to solve the above-mentioned problems in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] According to a first aspect of the present invention, a device for myocardial biopsy puncture comprises a surgical cap and a mounting member, wherein a mounting block is provided on one side of the surgical cap, a mounting frame is provided on the outside of the mounting block, a connecting bolt is provided on one side of the mounting frame, a connecting port is provided inside the mounting block, the connecting bolt is movably connected to the connecting port, and the connecting bolt is stuck in the connecting port, a mounting tube is provided inside the mounting frame, movable bolts are provided on the upper and lower sides of the mounting tube, movable ports are provided on the upper and lower sides of the mounting frame, the movable bolt is movably connected to the movable port, the mounting member is inside the mounting tube, a camera is provided at one end of the mounting member, a speaker is provided at the other end of the mounting member, a second screw port is provided on one side of the mounting tube, a second bolt is provided inside the second screw port, an elastic band is provided at the bottom of the surgical cap, a drawstring buckle is provided on the rear side of the elastic band, the interior of the surgical cap is sweat-absorbent material, a first screw port is provided on one side of the mounting block, a first bolt is provided inside the first screw port, the first bolt is threadedly connected to the first screw port, a motor is provided at the top of the mounting frame, and the motor is connected to the top movable bolt.

[0008] Furthermore, a limit strip is arranged on the outside of the mounting member, a limit rail is arranged on the inside of the mounting tube, the limit strip is slidably connected to the limit rail, a limit ring is arranged on the rear side of the limit strip, the second bolt is threadedly connected to the second screw mouth, and a fixing bolt is arranged on the top of the second bolt.

[0009] The myocardial biopsy puncture system includes a diagnosis and judgment module, a preoperative preparation module, an intraoperative operation module, a specimen retention module and a postoperative module, specifically:

[0010] The diagnosis and judgment module is used to evaluate the patient's physical condition before surgery, understand the patient's medical history, physical signs and related examination results in detail, and evaluate whether the patient is suitable for pericardiocentesis. At the same time, the patient and his family should be fully informed of the necessity, risks and possible complications of pericardiocentesis.

[0011] The preoperative preparation module includes an environment preparation module and an item preparation module, specifically:

[0012] Environmental preparation module, used to ensure that the operating environment is clean and tidy during pericardiocentesis, meet the sterile requirements, adjust the room temperature, and provide a comfortable position for the patient;

[0013] The item preparation module is used to prepare all the necessary items, including pericardiocentesis kit, gloves, local anesthetics, a full set of supplies for the rescue vehicle, specimen examination tubes, and disinfection supplies;

[0014] The intraoperative operation module includes a disinfection and anesthesia module and a puncture operation module, specifically:

[0015] The disinfection and anesthesia module is used to perform routine disinfection on the skin at the puncture site and then perform anesthesia with local anesthetics;

[0016] In the puncture operation module, at the selected puncture point, slowly insert the needle along the upper edge of the rib toward the spine. When you feel a sense of emptiness or fluid is withdrawn, it means that the puncture needle has entered the pericardial cavity.

[0017] The specimen retention module is used to retain an appropriate amount of specimens for inspection after extracting the effusion;

[0018] Postoperative module, used to remove the puncture needle, cover with sterile gauze, apply pressure for several minutes to stop bleeding, and fix with tape.

[0019] Furthermore, the output end of the intraoperative operation module is connected to the emergency treatment module, specifically:

[0020] The emergency response module is used to record the patient's sudden reaction to anesthesia or pericardiocentesis during surgery, and send out an alarm to notify the surgeon.

[0021] Furthermore, the output end of the intraoperative operation module is connected to the real-time reminder module, specifically:

[0022] The real-time reminder module is used to monitor the patient's vital signs. The real-time reminder module is connected to the ECG monitor to remind the doctor of the next step of the operation after each step of the operation.

[0023] If the doctor follows the system prompts, the system will enter silent mode after a short delay, ensuring that the doctor remains quiet during the operation, allowing the doctor to concentrate on the subsequent operation;

[0024] If an unexpected situation occurs during the operation and the doctor fails to follow the system prompts to proceed to the next surgical operation, the system's warning light will flash and need to be turned off manually; and the system will record that the doctor did not follow the system prompts. After the operation, the specific situation needs to be explained.

[0025] Furthermore, the intraoperative operation module also includes a body position adjustment module, specifically:

[0026] The body position adjustment module is used to determine whether the patient takes a semi-sitting position or a sloped lying position to expose the puncture site.

[0027] Furthermore, the intraoperative operation module also includes an information verification module, specifically:

[0028] The information verification module is used to check patient information to ensure accuracy.

[0029] Further, the following steps are included:

[0030] S1: First, the patient's body is examined before surgery through the diagnosis and judgment module to determine whether the patient's current condition is suitable for surgery;

[0031] S2: When the patient's physical condition is suitable for surgery, the preoperative preparation module is used to prepare the operating room environment and items required for surgery;

[0032] S3: The operation is then performed, during which disinfection and anesthesia are performed first, and finally the fluid in the pericardial cavity is extracted using a puncture needle;

[0033] S4: After the operation, remove the puncture needle and use gauze to stop the bleeding.

[0034] The present invention has the following advantages:

[0035] The operation is recorded by the camera, and the doctor is reminded by the speaker. When the camera angle cannot face the surgical position, the connecting bolt is rotated in the connecting port, so that the mounting frame drives the camera to be adjusted up and down. When the adjustment is completed, the first bolt is rotated in the first screw port to fix the inner connecting bolt, thereby fixing the angle of the mounting frame. The motor drives the movable bolt to rotate in the movable port, so that the mounting tube drives the mounting piece to be adjusted left and right, that is, it is convenient to adjust the angle of the camera;

[0036] Through the system's internal reminder module, the surgical operator can be reminded in real time. The entire system is small and can be worn in wireless headphones during surgical operations. It does not affect the normal operation of the operation. It solves the problem of errors and omissions in operating steps that are easily caused under tense situations, and avoids the situation where the chief physician reminds the patient on-site, which causes anxiety.

[0048] The myocardial biopsy puncture system includes a diagnosis and judgment module, a preoperative preparation module, an intraoperative operation module, a specimen retention module and a postoperative module, specifically:

[0049] The diagnosis and judgment module is used to evaluate the patient's physical condition before surgery, understand the patient's medical history, physical signs and related examination results in detail, and evaluate whether the patient is suitable for pericardiocentesis. At the same time, the patient and his family should be fully informed of the necessity, risks and possible complications of pericardiocentesis.

[0050] The preoperative preparation module includes an environment preparation module and an item preparation module, specifically:

[0051] Environmental preparation module, used to ensure that the operating environment is clean and tidy during pericardiocentesis, meet the sterile requirements, adjust the room temperature, and provide a comfortable position for the patient;

[0052] The item preparation module is used to prepare all the necessary items, including pericardiocentesis kit (including puncture needle, syringe, vascular clamp, towel, gauze, etc.), gloves, local anesthetics, a full set of supplies for rescue vehicles, specimen examination tubes, and disinfection supplies;

[0053] The intraoperative operation module includes a disinfection and anesthesia module and a puncture operation module, specifically:

[0054] The disinfection and anesthesia module is used to perform routine disinfection on the skin at the puncture site and then perform anesthesia with local anesthetics;

[0055] In the puncture operation module, at the selected puncture point, slowly insert the needle along the upper edge of the rib toward the spine. When you feel a sense of emptiness or fluid is withdrawn, it means that the puncture needle has entered the pericardial cavity. At this time, you should fix the needle and slowly draw out the effusion.

[0056] The specimen retention module is used to retain an appropriate amount of specimens for inspection after extracting the effusion;

[0057] Postoperative module, used to remove the puncture needle, cover with sterile gauze, apply pressure for several minutes to stop bleeding, and fix with adhesive tape;

[0058] In the above embodiment, it should be noted that if pericardiocentesis is suitable, subsequent operations including risk notification and confirmation and signature of family members will be performed; if pericardiocentesis is not suitable, the specific reasons for not being suitable for pericardiocentesis should be found out, and an application should be made for a re-physical examination of the patient, and finally, whether pericardiocentesis should be performed will be determined based on the specific circumstances. Example 2

[0059] like Figures 1 to 3 As shown, the myocardial biopsy puncture system includes all the contents of Example 1. In addition, the output end of the intraoperative operation module is connected to the emergency treatment module, specifically:

[0060] The emergency treatment module is used to record the patient's sudden reaction to anesthesia or pericardiocentesis during surgery and send out an alarm to notify the surgeon;

[0061] In the above embodiment, it should be noted that when puncturing, the site with the largest amount of effusion is selected, but the puncture site should be as close to the heart as possible and as far away as possible to avoid damaging surrounding organs. If necessary, cardiac ultrasound positioning can be used to determine the puncture point, needle insertion direction and needle insertion distance. The puncture point is usually the angle between the xiphoid process and the left costal arch edge or the inner side of the apex. Example 3

[0062] like Figures 1 to 3As shown, the myocardial biopsy puncture system includes all the contents of Example 2. In addition, the output end of the intraoperative operation module is connected to the real-time reminder module, specifically:

[0063] The real-time reminder module is used to monitor the patient's vital signs. The real-time reminder module is connected to the ECG monitor to remind the doctor of the next step of the operation after each step of the operation.

[0064] If the doctor follows the system prompts, the system will enter silent mode after a short delay, ensuring that the doctor remains quiet during the operation, allowing the doctor to concentrate on the subsequent operation;

[0065] If the doctor encounters an unexpected situation during the operation and fails to perform the next surgical operation according to the system reminder, the system's warning light will flash and need to be turned off manually; and the system will record that the doctor did not perform the operation according to the system reminder. After the operation, the doctor needs to explain the specific situation;

[0066] In the above embodiment, it should be noted that if continuous drainage of pericardial effusion is required, after the operator determines that the puncture needle has entered the pericardial cavity, the assistant inserts the guide wire along the puncture needle, the operator withdraws the puncture needle, and the sharp knife slightly cuts the skin at the puncture point. Then, insert the dilator along the guide wire, twist forward to expand the skin and subcutaneous tissue at the puncture site, and then withdraw the dilator. Finally, insert the pericardial drainage tube along the guide wire and withdraw the guide wire, observe the drainage effect, and adjust the depth and position of the drainage tube appropriately if necessary to ensure smooth drainage. After fixing the drainage tube, connect the drainage bag, slowly drain and record the amount of fluid drained, and take a certain amount of specimens for inspection. The retention time of the drainage tube is determined according to the needs of the disease. After the condition stabilizes, the drainage tube can be pulled out, covered with sterilized gauze and compressed for several minutes, and fixed with adhesive tape. Example 4

[0067] like Figures 1 to 3 As shown, the myocardial biopsy puncture system includes all the contents of Example 3. In addition, the intraoperative operation module also includes a body position adjustment module, specifically:

[0068] The body position adjustment module is used to determine whether the patient takes a semi-sitting position or a sloped lying position to expose the puncture site;

[0069] In the above embodiment, it should be noted that a cardiac ultrasound examination must be performed before pericardiocentesis to determine the amount of effusion, the puncture site, the puncture direction and the distance of the needle. The puncture site is usually selected with the largest amount of effusion and the point closest to the body surface. If pericardial puncture and fluid extraction can be performed under the guidance of ultrasound imaging, it will be more accurate and safer. Example 5

[0070] like Figures 1 to 3As shown, the myocardial biopsy puncture system includes all the contents of Example 4. In addition, the intraoperative operation module also includes an information verification module, specifically:

[0071] Information verification module, used to check patient information to ensure accuracy;

[0072] In the above embodiment, it should be noted that during puncture, if bloody fluid is drawn out, attention should be paid to whether it coagulates. Bloody pericardial effusion is non-coagulating. If the drawn fluid coagulates quickly, it indicates that the myocardium or artery is damaged. The fluid withdrawal should be stopped immediately, and the occurrence of symptoms of cardiac tamponade should be closely observed, and appropriate rescue measures should be taken. Example 6

[0073] like Figures 1 to 3 As shown, the myocardial biopsy puncture method includes all the contents of Example 5, and further includes the following steps:

[0074] S1: First, the patient's body is examined before surgery through the diagnosis and judgment module to determine whether the patient's current condition is suitable for surgery;

[0075] S2: When the patient's physical condition is suitable for surgery, the preoperative preparation module is used to prepare the operating room environment and items required for surgery;

[0076] S3: The operation is then performed, during which disinfection and anesthesia are performed first, and finally the fluid in the pericardial cavity is extracted using a puncture needle;

[0077] S4: After the operation, remove the puncture needle and use gauze to stop bleeding;

[0078] In the above embodiments, it should be noted that, before the operation, echocardiography is used for positioning, the appropriate needle insertion site and direction are selected, the operation is performed carefully, and the needle is inserted slowly to avoid damaging surrounding organs.
