Description

Technical Field

[0001] The present invention relates to the technical field of pacemakers, and in particular to a multifunctional pacemaker lead conversion device and an application method thereof. Background Art

[0002] The pacemaker consists of a main unit and electrodes. In the prior art, pacemakers are divided into temporary pacemakers and permanent pacemakers according to the functional design of the product and the patient's adaptive symptoms. Among them, temporary pacemakers are mainly used to ensure the safety of patients in emergency situations or within a short period of time, and can also serve as transitional treatment. Temporary pacemakers are mainly connected to a main unit placed outside the body through electrodes to maintain the patient's life and heart rate stability, and the retention time is usually no more than two weeks. Permanent pacemakers need to be implanted in the body, a skin bag is made in the body, the electrodes are connected to the main unit through the heart and buried under the skin, and need to be carried for a long time.

It consists of a permanent pacemaker and two permanent electrodes, which are inserted into the heart through a vein and transmit electrical signals to different parts of the heart to maintain normal heart rhythm. Compared with traditional single-chamber pacing, dual-chamber pacemakers have higher accuracy and adaptability. They can better simulate the electrical activity of a normal heart and improve the treatment effect by stimulating multiple myocardial cells at the same time. In addition, dual-chamber pacemakers can also be personalized according to the patient's specific situation to achieve the best treatment effect. When the battery of a patient's single-chamber pacemaker is exhausted and the patient is pacemaker-dependent, the single-chamber pacemaker may not be able to simulate the electrical activity of the heart normally, so a new permanent pacemaker needs to be replaced. With the development of science and technology, single-chamber pacemakers have gradually developed into dual-chamber pacemakers that can better simulate normal heart rhythms. Therefore, when a patient's single-chamber pacemaker battery is exhausted and a new permanent pacemaker is replaced, the decision to replace the patient's original single-chamber pacemaker with a dual-chamber pacemaker will be made based on the patient's specific situation and the doctor's advice. In order to better simulate the electrical activity of a normal heart and improve the patient's quality of life.

[0116] Specifically, a first permanent electrode and a first permanent pacemaker (i.e., a single-chamber pacemaker) connected to the first permanent electrode are implanted in the patient's body; in a method for converting a single-chamber pacemaker to a dual-chamber pacemaker disclosed in the present invention, any of the above-mentioned multifunctional pacemaker lead conversion devices is used to convert the original first pacemaker (i.e., a single-chamber pacemaker) to a dual-chamber pacemaker when the pacemaker battery of the pacemaker-dependent patient is exhausted, and the specific steps are as follows:

[0117] 1. Preoperative preparation: Conduct a detailed cardiac assessment of the patient's heart through electrocardiogram, cardiac ultrasound and other means to determine the patient's heart condition; and select the model of the dual-chamber pacemaker and the corresponding second permanent electrode based on the patient's cardiac assessment structure;

[0118] 2. Local anesthesia: Local anesthesia is administered in the surgical area to relieve the patient’s pain;

[0119] 3. Removal of the original permanent pacemaker: Expose the first permanent pacemaker implanted in the patient through an incision;

[0120] First, the temporary pacemaker is connected to the temporary electrode male connector 5 of the multifunctional pacemaker lead conversion device, and then the permanent electrode is disconnected from the first permanent pacemaker, and then the first permanent electrode is connected to the permanent electrode female connector 2 of the multifunctional pacemaker lead conversion device, so that the first permanent electrode can be connected to the temporary pacemaker more quickly through the multifunctional pacemaker lead conversion device;

[0121] 4. Implant a new permanent pacemaker: implant the second permanent electrode into the patient's heart. It should be noted that the venous access needs to be reopened when implanting the second permanent electrode into the patient's heart. Test the working status of the second permanent electrode. If the working status of the second permanent electrode is normal, connect the second permanent electrode to the dual-chamber pacemaker.

[0122] Then disconnecting the first permanent electrode from the multifunctional pacemaker lead conversion device, and removing the temporary pacemaker and the multifunctional pacemaker lead conversion device;

[0123] Testing the working state of the first permanent electrode; and connecting the tested first permanent electrode to the dual-chamber pacemaker;

[0124] 5. Parameter setting and functional testing of permanent pacemakers: set the parameters of dual-chamber pacemakers to suit the patient's heart condition;

[0125] Test the function of the dual-chamber pacemaker to ensure that it can effectively temporarily pace the heart;

[0126] 6. Incision suture: After confirming that the dual-chamber pacemaker is working properly, implant the dual-chamber pacemaker into the patient's body and suture the incision.

[0127] As another application scenario of the present invention, the present invention also discloses a method for converting a single-chamber pacemaker to a cardiac resynchronization therapy pacemaker. Cardiac resynchronization therapy (CRT) is a non-drug treatment method for treating heart failure. It improves the contractile function and coordination of the heart by implanting a special pacemaker between the two ventricles of the heart, thereby improving the patient's quality of life and prognosis.

[0128] The main function of the cardiac resynchronization therapy pacemaker is to adjust the heart's contraction rhythm through electrical stimulation, so that the left and right ventricles contract at the same time, avoiding the decline of heart function due to uncoordinated ventricular contraction. In addition, CRT can also reduce the heart load and myocardial oxygen consumption, thereby alleviating symptoms and prolonging the patient's survival.

[0129] The conversion of single-chamber pacemaker to cardiac resynchronization therapy pacemaker is suitable for patients suffering from heart failure, left bundle branch block or intraventricular conduction delay. Through any of the above-mentioned multifunctional pacemaker lead conversion devices, the patient's original single-chamber pacemaker (i.e., the first permanent pacemaker) is replaced with a new cardiac resynchronization therapy pacemaker.

[0130] The specific steps are as follows:

[0131] 1. Preoperative preparation: Conduct a detailed cardiac assessment of the patient's heart through electrocardiogram, cardiac ultrasound and other means to determine the patient's heart condition; and select the model of cardiac resynchronization therapy pacemaker and the corresponding third permanent electrode based on the patient's heart assessment structure;

[0132] 2. Local anesthesia: Local anesthesia is administered in the surgical area to relieve the patient’s pain;

[0133] 3. Removal of the original permanent pacemaker: Expose the first permanent pacemaker implanted in the patient through an incision;

[0134] First, the temporary pacemaker is connected to the temporary electrode male connector 5 of the multifunctional pacemaker lead conversion device, and then the permanent electrode is disconnected from the first permanent pacemaker, and then the first permanent electrode is connected to the permanent electrode female connector 2 of the multifunctional pacemaker lead conversion device, so that the first permanent electrode can be connected to the temporary pacemaker more quickly through the multifunctional pacemaker lead conversion device;

[0135] 4. Implant a new permanent pacemaker: implant the third permanent electrode into the patient's heart and test the working status of the third permanent electrode; if the working status of the third permanent electrode is normal, connect the third permanent electrode to the cardiac resynchronization therapy pacemaker; it should be noted that the venous access needs to be reopened when the third permanent electrode is implanted into the patient's heart;

[0136] Then disconnecting the first permanent electrode from the multifunctional pacemaker lead conversion device, and removing the temporary pacemaker and the multifunctional pacemaker lead conversion device;

[0137] Testing the working state of the first permanent electrode; and connecting the tested first permanent electrode to a cardiac resynchronization therapy pacemaker;

[0138] 5. Parameter setting and functional testing of permanent pacemakers: Set parameters of cardiac resynchronization therapy pacemakers to suit the patient's heart condition;

[0139] Testing the functionality of cardiac resynchronization therapy pacemakers to ensure they are effectively pacing the heart temporarily;

[0140] 6. Incision suture: After confirming that the cardiac resynchronization therapy pacemaker is working properly, the cardiac resynchronization therapy pacemaker is implanted into the patient's body and the incision is sutured.

[0141] After a patient has a permanent pacemaker implanted, the permanent pacemaker may be exposed due to infection, mechanical factors, patient skin, etc. Therefore, after the permanent pacemaker is exposed, medical staff will re-implant the permanent pacemaker into the patient's body after detecting that the permanent pacemaker functions normally. Therefore, the present invention also discloses a method for re-implanting a permanent pacemaker, using any of the multifunctional pacemaker lead conversion devices described above to re-implant the exposed pacemaker into the patient's body.

[0142] The specific steps include:

[0143] exposing, through the incision, a first permanent pacemaker implanted in a pocket of the patient;

[0144] First, the temporary pacemaker is connected to the temporary electrode male end of the multifunctional pacemaker lead conversion device, and then the permanent electrode is disconnected from the first permanent pacemaker, and the first permanent electrode is connected to the permanent electrode female end of the multifunctional pacemaker lead conversion device;

[0145] Debridement of the patient's pocket was performed;

[0146] Disinfect the first permanent pacemaker;

[0147] Disconnecting the first permanent electrode from the multifunctional pacemaker lead conversion device, removing the temporary pacemaker and the multifunctional pacemaker lead conversion device, and reconnecting the first permanent pacemaker to the first permanent electrode;

[0148] The first permanent pacemaker is re-implanted into the patient's pocket and the interface is sutured.

[0149] It has also been found in actual use that some patients will have allergic reactions to the materials of the permanent pacemaker after implantation. Therefore, when patients are allergic to the materials of the permanent pacemaker, they need to be treated urgently and replaced with a new permanent pacemaker to eliminate the allergens in the patient's body. Therefore, as another application scenario of the present invention, the present invention also discloses an emergency treatment method for patients who are allergic to permanent pacemakers. The multifunctional pacemaker lead conversion device described in any of the above items is used to treat the patient urgently and assist in replacing a new permanent pacemaker.

[0150] The specific steps include:

[0151] exposing, through the incision, a first permanent pacemaker implanted in a pocket of the patient;

[0152] First, connect the temporary pacemaker to the temporary electrode male end of the multifunctional pacemaker lead conversion device; then disconnect the permanent electrode from the first permanent pacemaker, and connect the first permanent electrode to the permanent electrode female end of the multifunctional pacemaker lead conversion device;

[0153] Debride the patient's pocket and check the patient for allergies;

[0154] A new fourth permanent electrode is customized based on the patient’s allergens;

[0155] Disconnecting the first permanent electrode from the multifunctional pacemaker lead conversion device, removing the temporary pacemaker and the multifunctional pacemaker lead conversion device, and connecting the first permanent electrode to a new fourth permanent pacemaker;

[0156] Setting parameters of the fourth permanent pacemaker to suit the patient's heart condition;

[0157] Test the function of the fourth permanent pacemaker to ensure that it is pacing the heart;

[0158] After confirming that the fourth permanent pacemaker is working properly, the fourth permanent pacemaker is re-implanted into the patient's pouch and the interface is sutured.

[0159] As another application scenario of the present invention, the present invention also discloses a method of using a permanent pacemaker for temporary cardiac pacing of a patient.

[0160] Specific:

[0161] Temporary pacemakers are usually used for short-term treatment, such as while waiting for permanent pacemaker implantation surgery or during acute arrhythmia attacks. It can help maintain a stable heart rate to ensure that blood can flow normally to all parts of the body. Because the thigh vein is relatively large and close to the heart, insertion is relatively easy, so temporary pacemakers are usually inserted through the thigh vein. In the operating room, the doctor will insert a thin temporary electrode into the thigh vein under local anesthesia, and then guide the temporary electrode to the inside of the heart, while the end of the temporary electrode will stay outside the patient's body and be connected to a temporary pacemaker. Moreover, the temporary pacemaker is relatively large in size, especially for infants and young children. Infants and young children need other accompanying personnel to hold them during daily activities, so the larger temporary pacemaker is not convenient for accompanying personnel to carry. Therefore, in the present invention, after the temporary electrode is implanted in the patient's body, one end of the temporary electrode placed outside the patient's body is connected to the temporary electrode female head 4 of any of the above-mentioned multifunctional pacemaker lead conversion devices, and the permanent pacemaker is connected to the permanent electrode male head 3 of the multifunctional pacemaker lead conversion device, so that the permanent pacemaker can send electrical pulses to the temporary electrode through the multifunctional pacemaker lead conversion device.

[0162] The specific method includes the following steps:

[0163] Perform local infiltration anesthesia near the puncture point, use a puncture needle to puncture the femoral vein, implant a guide wire into the femoral vein, and deliver the vascular sheath into the femoral vein;

[0164] One end of the temporary electrode is delivered into the heart through a vascular sheath, and the other end is placed outside the patient's body;

[0165] The end of the temporary electrode placed outside the patient's body is electrically connected to the temporary electrode female end of the multifunctional pacemaker lead conversion device; the permanent pacemaker is connected to the permanent electrode male end of the multifunctional pacemaker lead conversion device;

[0166] Set parameters of permanent pacemakers to suit the patient's heart condition;

[0167] Testing the function of a permanent pacemaker to ensure it can effectively temporarily pace the heart;

[0168] After confirming that the permanent pacemaker is working properly, fix the temporary electrodes and permanent pacemaker to prevent displacement.

[0169] It should be emphasized that the above-mentioned various applicable scenarios are merely several common scenarios of the multifunctional pacemaker lead conversion device provided by the present invention, and the usage of the multifunctional pacemaker lead conversion device provided by the present invention is not limited to the above-mentioned scenarios. In other words, as long as the multifunctional pacemaker lead conversion device provided by the present invention is used in application scenarios for conversion between pacemakers, it is applicable to the present invention and is within the protection scope of the present invention.

[0170] As a supplementary explanation, the multifunctional pacemaker lead conversion device provided by the present invention can realize external connection of a temporary pacemaker through the conversion device when a permanent pacing electrode is implanted in the patient's body; it can also realize external connection of a permanent pacemaker through the conversion device when a temporary pacemaker has been implanted in the patient.

[0171] Application environment one: when a permanent pacing electrode is implanted in the patient's body, a temporary pacemaker is connected externally through the conversion device. The advantage is that the permanent pacing electrode implanted in the body can be implanted via the internal jugular vein, subclavian vein or axillary vein. Compared with the temporary pacing electrode, the position is more stable and the parameters are more rational. It can be used in patients who need a longer temporary pacing transition (for example, several weeks or months), such as patients waiting for a heart transplant, to obtain more stable pacing parameters. At this time, the multifunctional pacemaker lead conversion device provided by the present invention can connect the permanent pacing electrode-temporary pacemaker externally.

[0172] Application environment two, when the patient has implanted a temporary pacemaker, the permanent pacemaker is connected externally through the conversion device. The advantage is that some patients who need a longer temporary pacing transition period, if temporary pacing electrodes have been implanted, but the patient cannot tolerate long-term bed rest and needs to move, the temporary pacemaker is bulky and inconvenient to wear; at this time, the multifunctional pacemaker lead conversion device provided by the present invention can connect the temporary pacemaker to the permanent pacemaker externally.

[0173] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
