Description

Electrode lead adapter and temporary pacemaker Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an electrode lead adapter and a temporary pacemaker. Background Art

[0002] Temporary pacemakers are widely used, mainly to meet the following three needs:

[0003] (1) Preventive needs: Applicable to any patient with potential temporary pacing protection needs, such as patients in the perioperative period of surgical valve replacement, transcatheter valve intervention, radiofrequency ablation of heart rate indicators, permanent pacemaker infection removal, hypertrophic myocardium and surgical resection or chemical ablation.

[0004] (2) Therapeutic needs: any patient who requires temporary pacing treatment, such as patients with pacing indications due to any surgical procedure, patients whose recovery is unpredictable, patients with acute myocardial infarction, patients after percutaneous coronary intervention, etc.

[0005] (3) Transitional needs: protective treatment during the period when the original implanted pacemaker is removed for any reason and a replacement pacemaker is waiting to be implanted.

[0006] The use of temporary pacemakers can not only prevent patients from experiencing adverse events due to bradycardia after surgery, but also prevent patients from prematurely implanting unnecessary permanent pacemakers.

[0007] In the prior art, the configuration of the adapter on the temporary pacemaker is basically designed for temporary pacing floating electrodes and / or epicardial temporary pacing electrodes. Therefore, these temporary pacemakers can only be connected to temporary pacing floating electrodes or epicardial temporary pacing electrodes, but cannot be connected to the standard IS-1 electrode wire, which works more stably and reliably.

[0052] One of the purposes of the present invention is to provide an electrode lead adapter device that can simultaneously adapt to multiple electrode leads including standard IS-1 electrode leads, temporary pacing floating electrode leads, and epicardial temporary pacing electrode leads. Therefore, when the adapter device is used to be set on a temporary pacemaker, the temporary pacemaker can be adapted to different electrode leads, effectively expanding the indications and application scenarios of a single temporary pacemaker.

[0053] A second object of the present invention is to provide a temporary pacemaker equipped with the aforementioned switching device of the electrode wire.

[0054] To make the objects, advantages, and features of the present invention more apparent, the present invention is further described below in detail with reference to the accompanying drawings. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar components.

[0055] To facilitate understanding of the present invention, the structures of a temporary pacemaker, a standard IS-1 electrode lead, a temporary pacing floating electrode lead, and an epicardial temporary pacing electrode lead are briefly introduced.

[0056] 4 and 14 , the temporary pacemaker includes a housing 10, an adapter 20, an electrical component 30, and a conductor 40. The adapter 20 and the electrical component 30 are both mounted on the housing 10 and electrically connected via the conductor 40. The electrical component 30 includes a wireless communication module, such as a Bluetooth communication module, a radio frequency communication module, or a Wi-Fi module, which performs functions such as pacing, sensing, and heart rate response. During operation of the temporary pacemaker, the electrical component 30 adjusts the operating parameters of the pacemaker.

[0057] Referring to Figures 6 and 16 , the standard IS-1 electrode lead includes two electrodes, namely a first electrode 01 and a second electrode 02. The first electrode 01 and the second electrode 02 are arranged along the axis of the standard IS-1 electrode lead and extend along the axis of the standard IS-1 electrode lead. The end of the first electrode 01 away from the second electrode 02 is a free end. The first electrode 01 and the second electrode 02 are connected by an insulating spacer 03. When the standard IS-1 electrode lead is connected to a temporary pacemaker via an adapter 20, the first electrode 01 and the second electrode 02 should be electrically conductive with the electrical component 30 of the temporary pacemaker through the adapter 20.

[0058] Referring to Figures 7, 8, 17, and 18, the epicardial temporary pacing lead includes an electrode, referred to as third electrode 04. Third electrode 04 is longer and thinner than the two electrodes of a standard IS-1 lead. When the epicardial temporary pacing lead is connected to a temporary pacemaker via adapter 20, third electrode 04 is electrically connected to electrical assembly 30 via adapter 20.

[0059] Referring to Figures 9 and 19 , the temporary pacing floating electrode includes an electrode, referred to as fourth electrode 05. Fourth electrode 05 is shorter and thicker than first electrode 01 of a standard IS-1 electrode lead. When the temporary pacing floating electrode lead is connected to the temporary pacemaker via adapter 20, fourth electrode 05 is electrically connected to electrical assembly 30 via adapter 20.

[0060] Next, the structure of the switching device 20 will be introduced in detail.

[0061] Figures 1 and 10 show exploded views of an adapter 20 provided in an embodiment of the present invention. Referring to Figures 1 and 10, the adapter 20 includes a conductive block 100, an insulating movable member 200, and a conductive elastic member 300. The conductive block 100 and the insulating movable member 200 are arranged along a first direction, and the insulating movable member 200 is provided with a second channel 201 extending through the conductive block 100 in the first direction. The insulating movable member 200 is movable relative to the conductive block 100 in the first direction to move closer to or further away from the conductive block 100. The conductive elastic member 300 is connected to the insulating movable member 200 and at least partially moves with the insulating movable member 200. The conductive elastic member 300 also includes a contact portion (not labeled in the figures). The adapter 20 is configured such that when the insulating movable member 200 moves away from the conductive block 100, the contact portion is movable in a direction close to the axis of the second channel 201; and when the insulating movable member 200 moves toward the conductive block 100, the contact portion is movable in a direction away from the axis of the second channel 201.

[0062] Referring to Figures 5, 6, 16, and 17, when the adapter 20 is mounted on the housing 10, the conductive block 100 is fixedly connected to the housing 10, and the insulating movable member 200 is movable along a first direction on the housing 10. The wire 40 connects both the conductive block 100 and the electrical component 30, and also connects the conductive elastic member 300 and the electrical component 30. Specifically, the wire 40 includes a first wire 41 and a second wire 42, which are separate from each other. The first wire 41 connects the conductive block 100 and the electrical component 30, and the second wire 42 connects the conductive elastic member 300 and the electrical component 30.

[0063] A temporary pacemaker equipped with an adapter 20 can be adapted to a standard IS-1 electrode lead. Specifically, as shown in Figures 6 and 16, the first electrode 01 of the standard IS-1 electrode lead can be inserted into the second channel 201, and in the process, a force is applied to the insulating movable member 200, driving the insulating movable member 200 to move in a direction away from the conductive block 100, so that the contact portion moves in a direction close to the axis of the second channel 201 until the contact portion contacts the first electrode 01. Thus, electrical conduction between the first electrode 01 and the electrical component 30 can be achieved through the second wire 42 and the conductive elastic member 300. At the same time, the second electrode 02 partially contacts the conductive block 100, thereby achieving electrical conduction between the second electrode 02 and the electrical component 30 through the conductive block 100 and the first wire 41.

[0064] A temporary pacemaker equipped with the adapter 20 can also be adapted for epicardial temporary pacing electrode leads. Specifically, referring to Figures 7, 8, 17, and 18, a portion of the third electrode 04 is inserted into the second channel 201, while the other portion remains within the first channel 101. During this process, since the third electrode 04 is relatively thin, it does not contact the inner surface of the second channel 201 or the contact force is extremely small. Therefore, the third electrode 04 will basically not push the insulating movable member 200 to move in a direction away from the conductive block 100, and the contact portion will basically not move in a direction close to the second channel 201, and will not contact the third electrode 04. Instead, the third electrode 04 is partially in contact with the conductive block 100, and is electrically connected to the electrical component 30 through the conductive block 100 and the first lead 41.

[0065] A temporary pacemaker equipped with an adapter 20 can also be adapted for temporary pacing floating electrode leads. Specifically, please refer to Figures 9 and 19. A portion of the fourth electrode 05 is inserted into the second channel 201, and the other portion is in contact with the conductive block 100. During this process, since the fourth electrode 05 is relatively short, depending on the specific configuration of the adapter 20, it will not push the insulating movable member 200 to move in a direction away from the conductive block 100, or although it will push the insulating movable member 200 to move in a direction away from the conductive block 100, it will not reach the area where the contact portion is located and will not contact the contact portion. The specific form will be described in detail later. The fourth electrode 05 is electrically connected to the electrical component 30 through the conductive block 100 and the first wire 41.

[0066] Therefore, the temporary pacemaker equipped with the adapter device 20 can be adapted to different electrode wires to expand the indications and applicable scenarios of a single temporary pacemaker, which is beneficial for doctors to choose appropriate treatment methods according to the patient's specific situation and improve the treatment effect.

[0067] It should be noted that the aforementioned “when the insulating movable member 200 moves in a direction away from the conductive block 100, the contact portion can move in a direction close to the axis of the second channel 201” includes both the situation that the conductive elastic member 300 at least partially moves with the insulating movable member 200 and enables the contact portion to move autonomously in a direction close to the axis of the second channel 201, and also includes the situation that the conductive elastic member 300 at least partially moves with the insulating movable member 200 and also enables the contact portion to move in a direction close to the axis of the second channel 201 with the help of other components. The situation of movement; “when the insulating movable member 200 moves in a direction close to the conductive block 100, the contact portion can move in a direction away from the axis of the second channel 201”, includes both the situation that the conductive elastic member 300 at least partially moves with the insulating movable member 200, and the contact portion autonomously moves in a direction away from the axis of the second channel 201, and also includes the situation that the conductive elastic member 300 at least partially moves with the insulating movable member 200, and the contact portion moves in a direction away from the axis of the second channel 201 with the help of other components.

[0068] Optionally, in an embodiment of the present invention, the conductive block 100 is further provided with a first channel 101 extending therethrough in a first direction. The position of the first channel 101 corresponds to the position of the second channel 201, and the first channel 101 is used to accommodate an electrode. Specifically, when the temporary pacemaker is adapted to a standard IS-1 electrode lead, the first channel 101 accommodates a portion of the second electrode 02, so that the second electrode 02 contacts the conductive block 100. When the temporary pacemaker is adapted to an epicardial temporary pacing electrode lead, the first channel 101 accommodates a portion of the third electrode 04, so that the third electrode 04 contacts the conductive block 100. When the temporary pacemaker is adapted to a temporary floating pacing electrode lead, the first channel 101 accommodates a portion of the fourth electrode 05, so that the fourth electrode 05 contacts the conductive block 100.

[0069] The following describes the configuration of the adapter 20 through specific embodiments. It should be noted that the following describes the adapter 20 in the form of enumeration only, which is not exhaustive of all possible configurations of the adapter 20 and therefore should not constitute an undue limitation on the present invention.

[0070] <Example 1>

[0071] Please refer to Figure 1. In this embodiment, the conductive block 100 includes a conductive block body 110 and a fastener 120. The conductive block body 110 is used to be fixedly connected to the housing 10, and a first channel 101 is provided on the conductive block body 110, and a mounting hole 111 is also provided on the conductive block body 110. The mounting hole 111 extends along the second direction and is connected to the first channel 101. The second direction intersects with the first direction, and preferably the second direction is perpendicular to the first direction. The fastener 120 is configured to be able to pass through the mounting hole 111 and partially extend into the first channel 101 to press against the electrode passed through the first channel 101, so that the electrode is fixed to the conductive block body 110, and the electrode wire is fixed to the conductive block 100. In practice, the mounting hole 111 can be a threaded hole, and the fastener 120 can be a fastening screw. In addition, it can be understood that the first channel 101 can be a slot structure as shown in Figure 1, or it can be a through hole (not shown in the figure).

[0072] 2 and 3 , the second channel 201 of the insulating movable member 200 is actually a through hole, such as a circular through hole. In this case, the second direction may be the radial direction of the second channel 201 .

[0073] At least one force transmission portion 210 extending along a third direction perpendicular to the first direction may be formed on the inner surface of the second channel 201. Preferably, there are multiple force transmission portions 210, each of which is equally spaced along the circumference of the second channel 201. It is understood that the area enclosed by the multiple force transmission portions 210 constitutes a portion of the second channel 201. In this embodiment, the radial dimensions of the area enclosed by the multiple force transmission portions 210 in the second channel 201 are comparable to the radial dimensions of the first electrode 01 of a standard IS-1 electrode lead. This allows the first electrode 01 to pass through the location of the force transmission portion 210 while still in contact and generating interaction forces. Furthermore, the radial dimensions of the area enclosed by the multiple force transmission portions 210 in the second channel 201 should be larger than the outer diameter of the third electrode 04 of the temporary epicardial pacing electrode lead and smaller than the outer diameter of the fourth electrode 05 of the temporary floating pacing electrode lead.

[0074] When the adapter 20 is adapted to the standard IS-1 electrode conductor, the force transmission portion 210 serves to transmit a force to drive the insulating movable member 200 to move in a direction away from the conductive block 100. Specifically, when the first electrode 01 of the standard IS-1 electrode conductor is partially inserted into the second channel 201 and the free end of the first electrode 01 passes through the position where the force transmission portion 210 is located, the side wall of the first electrode 01 is in close contact with the force transmission portion 210, and there is an interaction force between the two. In this way, during the advancement of the first electrode 01, the force transmission portion 210 can apply a force to the insulating movable member 200 along the axial direction of the second channel 201 (i.e., the first direction) and away from the conductive block 100. Theoretically, the more force transmission portions 210 there are, the more balanced the force on the insulating movable member 200 in the circumferential direction of the second channel 201 is, which is more conducive to the stable movement of the insulating movable member 200 along the first direction. However, when the number of force transmission portions 210 is too large, it is not conducive to the first electrode 01 passing through the position where the force transmission portion 210 is located in the second channel 201. In consideration of both the force stability and the convenience for the first electrode 01 to pass through the position of the force transmission part 210, the number of the force transmission parts 210 is usually set to three.

[0075] Preferably, as shown in FIG2 , the force transmission portion 210 is provided with an inclined surface 211, and the distance from the inclined surface 211 to the axis of the second channel 201 gradually decreases in a direction away from the conductive block 100. When the adapter 20 is adapted to the epicardial temporary pacing electrode lead, the inclined surface 211 is used to guide the third electrode 04 so that the third electrode 04 can pass through the position where the force transmission portion 210 is located, thereby minimizing the possibility that the third electrode 04 will apply a force to the insulating movable member 200 via the force transmission portion 210, thereby reducing the possibility that the contact portion of the conductive elastic member 300 will move toward the axis of the second channel 201 and contact the third electrode 04 due to the insulating movable member 200 moving away from the conductive block 100.

[0076] In this embodiment, the force transmission portion 210 is disposed on the side of the contact portion of the conductive elastic member 300 close to the conductive block 100. This is to prevent the conductive elastic member 300 from contacting the fourth electrode 05 when adapting to the temporary pacing floating insulated electrode wire.

[0077] When the adapter 20 is adapted to different electrode wires, the relative relationship between the force transmission portion 210 and the corresponding electrode will be described in detail later.

[0078] Optionally, in order to further improve the stability of the insulating movable member 200 moving along the first direction, please refer to Figures 2 and 3. A first guide portion 220 extending along the first direction is provided on the outer surface of the insulating movable member 200, and a second guide portion (not shown in the figure) extending along the first direction is provided on the housing 10. The second guide portion cooperates with the first guide portion 220 to guide the movement of the insulating movable member 200. In the figure, the first guide portion 220 is a guide groove, and the second guide portion is a guide protrusion. Alternatively, the first guide portion is a guide protrusion (not shown in the figure), and the second guide portion is a guide groove. Of course, the first guide portion and the second guide portion can also have other forms, as long as the two cooperate to guide the movement of the insulating movable member 200.

[0079] Referring back to Figure 1 , in this embodiment, the conductive elastic member 300 is an elongated structure extending along a first direction, such as a filamentary structure. It should be noted that the fact that the conductive elastic member 300 extends along the first direction does not necessarily mean that the conductive elastic member 300 must be a straight line. It can also be a partially curved or bent structure, as long as the conductive elastic member 300 has two opposing ends in the first direction.

[0080] The two opposing ends of the conductive elastic member 300 in the first direction are referred to as a first end 301 and a second end 302, respectively. The first end 301 of the conductive elastic member is closer to the conductive block 100 than the second end 302. The first end 301 of the conductive elastic member is connected to the insulating movable member 200 and moves synchronously with the insulating movable member 200. The second end 302 of the conductive elastic member can be directly or indirectly fixed to the housing 10 and remains stationary relative to the conductive block 100. The contact portion is located between the first end 301 and the second end 302 of the conductive elastic member.

[0081] The conductive elastic member 300 has an initial state and a deformed state. When the distance between the insulating movable member 200 and the conductive block 100 is the smallest, the conductive elastic member 300 is in the initial state. When the insulating movable member 200 moves away from the conductive block 100, the conductive elastic member 300 switches from the initial state to the deformed state.

[0082] Specifically, when the first end 301 of the conductive elastic member moves along with the insulating movable member 200 in a direction away from the conductive block 100, the portion of the conductive elastic member 300 between the first end 301 and the second end 302 bends toward the axis of the second channel 201, driving the contact portion to move in a direction closer to the axis of the second channel 201. Simultaneously, the conductive elastic member 300 stores elastic potential energy. When the conductive elastic member 300 releases this elastic potential energy, it switches from its deformed state to its initial state, causing the contact portion to move away from the axis of the second channel 201 and driving the insulating movable member 200 to move closer to the conductive block 100.

[0083] To ensure that the portion of the conductive elastic member 300 between the first end 301 and the second end 302 bends and deforms toward the axis of the second channel 201 as the first end 301 of the conductive elastic member moves with the insulating movable member 200 away from the conductive block 100, a designated area of ​​the conductive elastic member 300 is pre-arc-shaped during fabrication. When the conductive elastic member 300 and the insulating movable member 200 are assembled, the convex side of the arc faces the axis of the second channel 201. This allows the conductive elastic member 300 to bend further toward the axis of the second channel 201, guided by the arc, as the first end 301 of the conductive elastic member moves with the insulating movable member 200 away from the conductive block 100. Thus, the conductive elastic member 300 may include a first segment 310, a second segment 320, and a third segment 330 connected sequentially along a first direction. The first segment 310 and the third segment 330 may both be straight lines, and the area where the second segment 320 is located is pre-bent into an arc as a designated area. In this way, the convex side of the second segment 320 at least partially constitutes the contact portion. During assembly, the end of the first segment 310 facing away from the second segment 320 serves as the first end 301 of the conductive elastic member for connection to the insulating movable member 200. Correspondingly, the end of the third segment 330 facing away from the second segment 320 serves as the second end 302 of the conductive elastic member. The second segment 320 is located on the side of the force transmission portion 210 facing away from the conductive block 100, so that the contact portion is located on the side of the force transmission portion 210 facing away from the conductive block 100.

[0084] Preferably, this embodiment also features a special design for the cross-section of the conductive elastic member 300, such that the second segment 320 is less rigid than the first segment 310 and the third segment 330, making it more easily deformable. In one embodiment, the cross-sectional shapes of the first segment 310, the second segment 320, and the third segment 330 are identical, but the cross-sectional area of ​​the second segment 320 is the smallest.

[0085] Alternatively, only the cross section of the second segment 320 can be specially designed to facilitate bending of the second segment 320 toward the axis of the second channel 201. Specifically, the cross section of the second segment 320 has a radial dimension d1, and an axial dimension d2, where d1 is smaller than d2. The cross section of the second segment 320 can be elliptical, rectangular, or waist-shaped.

[0086] The number of conductive elastic members 300 is at least one, preferably multiple, and the multiple conductive elastic members 300 are spaced apart around the axis of the second channel 201. It should be understood that the multiple conductive elastic members 300 are directly or indirectly connected to the electrical component 30 via the second conductor 50. In other words, the multiple conductive elastic members 300 are arranged in parallel. This arrangement has the advantage that when the adapter 20 is adapted to a standard IS-1 electrode conductor, multiple conductive elastic members 300 are present around the circumference of the first electrode 01. As long as the first electrode 01 contacts the contact portion of one of the conductive elastic members 300, electrical conduction between the first electrode 01 and the electrical component 30 is achieved, thereby improving the success rate of adapting the adapter 20 to the standard IS-1 electrode conductor.

[0087] It should be noted that this embodiment does not specifically limit the connection method between the first end 301 of the conductive elastic member and the insulating movable member 200. In an optional implementation, please refer to Figure 3. The insulating movable member 200 is provided with a first engagement hole 202. The first engagement hole 202 can be a blind hole, and the number of the first engagement holes 202 is not less than the number of the conductive elastic members 300. Preferably, the number of the first engagement holes 202 is equal to the number of the conductive elastic members 300, and they are arranged in a one-to-one correspondence with the conductive elastic members 300. The first end 301 of each conductive elastic member is inserted into the corresponding first engagement hole 202, and the insulating movable member 200 and the first end 301 of the conductive elastic member are maintained relatively stationary by any suitable means, including but not limited to gluing, interference fit, etc.

[0088] Optionally, please continue to refer to Figure 1. The adapter 20 also includes a first insulating fixing member 400, which is arranged on the side of the insulating movable member 200 away from the conductive block 100. The first insulating fixing member 400 is used to be fixedly connected to the housing 10 to remain relatively stationary with the conductive block 100. The first insulating fixing member 400 is provided with a third channel 401 extending along the first direction. The third channel 401 extends at least to the surface of the first insulating fixing member 400 at one end close to the insulating movable member 200, and the third channel 401 is corresponding to the second channel 201, for example, coaxially arranged. A guide hole 402, which is a through hole, is also opened on the side wall of the first insulating fixing member 400 relative to the first direction. The guide hole 402 is connected to the third channel 401. The number of guide holes 402 is equal to the number of conductive elastic members 300, and each guide hole 402 is arranged corresponding to a conductive elastic member 300. In other words, when there is only one conductive elastic member 300, there is also only one guide hole 402, which is aligned with the conductive elastic member 300 in the circumferential direction of the second channel 201. When there are multiple conductive elastic members 300, there are also multiple guide holes 402, which are spaced apart around the axis of the third channel 401, with each guide hole 402 aligned with the corresponding conductive elastic member 300 in the circumferential direction of the second channel 201. During assembly, the second segment 320 of each conductive elastic member 300 is partially inserted into the corresponding guide hole 402. This allows the convex side of the second segment 320 to bend further toward the axis of the second channel 201, constrained by the guide hole 402, to avoid deviation. Furthermore, the bent and deformed second segment 320 can contact the electrode, thereby achieving electrical connection.

[0089] Optionally, the conductive elastic member 300 may also be connected to the first insulating fixing member 400 so that the second end 302 of the conductive elastic member remains relatively stationary with respect to the conductive block 100. Specifically, referring again to FIG1 , the first insulating fixing member 400 includes a first base 410 and a first engaging portion 420. The first base 410 is provided with the aforementioned third channel 401 and guide hole 402. The first engaging portion 420 is disposed on the outer surface of the first base 410 and is located on the side of the guide hole 402 away from the insulating movable member 200. The first engaging portion 420 is provided with second engaging holes 421 extending through it in a first direction. The number of second engaging holes 421 is no less than the number of conductive elastic members 300, and preferably, the number of second engaging holes 421 is equal to the number of conductive elastic members 300, and they are provided in a one-to-one correspondence with each conductive elastic member 300. Each conductive elastic member 300 is partially inserted into a corresponding second engaging hole 421. The conductive elastic member 300 may be interference fit with the second engaging hole 421, or may be connected via an adhesive.

[0090] Furthermore, when there are multiple conductive elastic members 300, the adapter 20 preferably also includes a conductive bonding sheet 500. The conductive bonding sheet 500 is disposed on a side of the first insulating fixture 400 away from the insulating movable member 200 and is electrically connected to all of the conductive elastic members 300. Simultaneously, a second conductive wire 42 connects the conductive bonding sheet 500 to the electrical component 30. This allows a single second conductive wire 42 to connect all of the conductive elastic members 300 to the electrical component 30. It will be appreciated that the conductive bonding sheet 500 can be connected to either the first insulating fixture 400 or the housing 10.

[0091] Figures 4 and 5 illustrate the structure of a temporary pacemaker equipped with the adapter device 20 provided in this embodiment. The conductive block body 110 and the first insulating fixture 400 of the conductive block 100 are fixedly connected to the housing 10. The insulating movable member 200 engages with the second guide portion of the housing 10 via the first guide portion 220. When not in use, a gap exists between the insulating movable member 200 and the first insulating fixture 400 to allow the insulating movable member 200 to move away from the conductive block 100.

[0092] When the temporary pacemaker is adapted to different electrode leads, the operation process of each component of the switching device 20 is described as follows. It should be understood that when the temporary pacemaker is not adapted to the electrode lead, the switching device 20 thereon is in an initial state.

[0093] When a temporary pacemaker is adapted for use with a standard IS-1 electrode lead, as shown in Figure 6 , the first electrode 01 is inserted through the first channel 101 into the second channel 201. After the free end of the first electrode 01 passes through the force transmission portion 210, the sidewall of the first electrode 01 contacts the force transmission portion 210, which then applies a force to the insulating movable member 200 along the axis of the second channel 201 (i.e., the first direction) and away from the conductive block 100. As the first electrode 01 continues to advance, the insulating movable member 200 moves away from the conductive block 100, and the contact portion of the conductive elastic member 300 moves in a direction closer to the axis of the second channel 201, until the first electrode 01 enters the third channel 401 and contacts the contact portion of at least one conductive elastic member 300. At this point, the adapter 20 is in a deformed state. Simultaneously, the second electrode 02 is partially located within the first channel 101. The fastener 120 then presses against the second electrode 02 to secure the standard IS-1 electrode lead. Subsequently, the temporary pacemaker can be used normally by energizing the electrical assembly 30. To disconnect the temporary pacemaker from the standard IS-1 electrode lead, simply release the pressure of the fastener 120 on the second electrode 02 and remove the standard IS-1 electrode lead. The conductive elastic member 300 will automatically release its elastic potential energy, driving the insulating movable member 200 to move toward the conductive block 100, thereby restoring the adapter 20 to its initial state.

[0094] When the temporary pacemaker is adapted for the epicardial temporary pacing electrode lead, the third electrode 04 is controlled to be inserted into the second channel 201 via the first channel 101 and continuously advanced along the inclined surface 211 through the area where the force transmission portion 210 is located until it can no longer be pushed. During this process, when the third electrode 04 contacts the inclined surface 211, it may push the insulating movable member 200 to move in a direction away from the conductive block 100. After the free end of the third electrode 04 passes through the force transmission portion 210, it will basically not push the insulating movable member 200 to move. After the third electrode 04 is pushed into place, it still partially remains in the first channel 101. At this time, the fastener 120 presses against the third electrode 04 to lock the epicardial temporary pacing electrode lead. Ideally, the third electrode 04 maintains a straight configuration as shown in Figure 7 throughout the operation. In some cases, the third electrode 04 may bend (as shown in Figure 8), but this does not basically affect the normal use of the temporary pacemaker. When it is necessary to remove the temporary pacemaker and the epicardial temporary pacing electrode lead, it is only necessary to release the pressure of the fastener 120 on the second electrode 02 and pull out the epicardial temporary pacing electrode lead.

[0095] When the temporary pacemaker is adapted for a temporary pacing floating electrode, as shown in Figure 9, the fourth electrode 05 is controlled to be inserted into the second channel 201 via the first channel 101. The fourth electrode 05 is relatively thick and does not pass through the force transmission portion 210, but instead abuts against the inclined surface 211. As a result, during advancement of the fourth electrode 05, the fourth electrode 05 pushes the insulating movable member 200 away from the conductive block 100 via the inclined surface 211 until the fourth electrode 05 can no longer be advanced. Since the fourth electrode 05 does not pass through the force transmission portion 210, it does not enter the third channel and does not come into contact with the conductive elastic member 300. It can be understood that when the fourth electrode 05 is unable to advance, it is partially located within the first channel 101. At this point, the fastener 120 is used to press against the fourth electrode 05, locking the temporary pacing floating electrode. To disconnect the temporary pacemaker from the epicardial temporary pacing electrode lead, simply release the fastener 120 from pressing against the second electrode 02 and remove the temporary pacing floating electrode lead.

[0096] <Example 2>

[0097] As shown in FIG10 , the structure of the conductive block 100 in this embodiment may be the same as that in the first embodiment, and will not be described in detail here. The configurations of other components are different.

[0098] Alternatively, please continue to refer to Figure 10 and combine it with Figure 11. The insulating movable member 200 in this embodiment includes a fourth segment 240 and a fifth segment 250 connected along the first direction. The fourth segment 240 and the fifth segment 250 can both be cylindrical structures, and the inner diameter of the fourth segment 240 is larger than the inner diameter of the fifth segment 250, and the outer diameter of the fourth segment 240 is larger than the outer diameter of the fifth segment 250. Thus, the fourth segment 240 and the fifth segment 250 are connected by a joining wall (not marked in the figure), the joining wall is perpendicular to the first direction, and the surface of the joining wall located in the second channel 201 is formed as a step surface 203. The fourth segment 240 is closer to the conductive block 100 than the fifth segment 250.

[0099] Preferably, a force transmission portion 210 is provided on the inner surface of the fifth segment 250. The specific structure of the force transmission portion 210 can be found in Example 1 and will not be described in detail here. However, in this embodiment, the radial dimension of the area enclosed by the multiple force transmission portions 210 can be smaller than the outer diameter of the first electrode 01 of a standard IS-1 electrode wire, such that the free end of the first electrode 01 cannot pass through the location of the force transmission portion 210.

[0100] As shown in Figures 10, 12 and 13, the conductive elastic member 300 includes a second joint portion 340 and a cantilever 350. The second joint portion 340 is, for example, a joint arm. The second joint portion 340 is directly or indirectly connected to the insulating movable member 200. In an optional implementation, the second joint portion 340 is connected to the side of the insulating movable member 200, for example, on the outer side of the insulating movable member 200. The second joint portion 340 is also parallel to the axis of the second channel 201. The cantilever 350 is arranged in the second channel 201 and is located at the fourth segment 240, so that the cantilever 350 is located on the side of the step surface 203 facing the conductive block 100. The cantilever 350 has a third end 351 and a fourth end 352 opposite to each other in the first direction, and the third end 351 of the cantilever is closer to the conductive block 100 than the fourth end 352 of the cantilever. The third end 351 of the cantilever is connected to an end of the second joint portion 340 close to the conductive block 100 . The fourth end 352 of the cantilever is a free end and constitutes a contact portion.

[0101] Optionally, there are multiple cantilevers 350, and the multiple cantilevers 350 are spaced apart around the axis of the second channel 201. The number of second joints 340 is not less than the number of cantilevers 350, and generally the number of the two is equal, and each second joint 340 is connected to a cantilever 350. Preferably, the conductive elastic member 300 also includes a third joint 360, which is an annular member that is simultaneously connected to the end of all the second joints 340 away from the conductive block 100. In this way, when the adapter 20 is applied to a temporary pacemaker, the effect of connecting all the cantilevers 350 to the electrical component 30 can be achieved by connecting a second wire 42 to the third joint 360. The following description is based on the example of multiple cantilevers 350.

[0102] For more details, please refer to Figures 12 and 13. In this embodiment, Figure 12 shows the conductive elastic member 300 in its natural state, while Figure 13 shows the cantilever 350 of the conductive elastic member 300 subjected to a force in a first direction directed from the insulating movable member 200 toward the conductive block 100. In Figure 13, the conductive elastic member 300 stores elastic potential energy. In Figure 12, the distance between the fourth end 352 and the axis of the second channel 201 is L1. In Figure 13, the distance between the fourth end 352 of the cantilever and the axis of the second channel 201 is L2, with L1 being greater than L2. That is, when the conductive elastic member 300 is subjected to a force directed from the insulating movable member 200 toward the conductive block 100, the fourth end 352 of the cantilever moves in a direction closer to the axis of the second channel 201, causing the conductive elastic member 300 to store elastic potential energy. When the conductive elastic member 300 releases its elastic potential energy, the fourth end 352 of the cantilever moves in a direction away from the axis of the second channel 201. The advantage of this type of conductive elastic member 300 is that when the adapter 20 is not in use, the conductive elastic member 300 is in a natural state rather than a state of long-term stress, is not prone to fatigue, and has a longer service life.

[0103] Based on the configuration of the conductive elastic member 300, please refer back to Figure 11. The joint wall is provided with avoidance holes 204 extending through along the first direction. The number of avoidance holes 204 is equal to the number of cantilevers 350, which is a plurality. The multiple avoidance holes 204 are arranged in a one-to-one correspondence with the multiple cantilevers 350. Please refer back to Figure 10 again. The adapter 20 also includes a second insulating fixing member 600. The second insulating fixing member 600 is arranged on the side of the fourth segment 240 away from the conductive block 100, and is used to be fixed on the shell 10 to remain relatively stationary with the conductive block 100. The second insulating fixing member 600 includes a rod-shaped structure 611 extending along the first direction. The number of rod-shaped structures 611 is equal to the number of cantilevers 350, which is a plurality. The multiple rod-shaped structures 611 are arranged in a one-to-one correspondence with the multiple cantilevers 350, and thus are also arranged in a one-to-one correspondence with the multiple avoidance holes 204.

[0104] In this way, when the insulating movable member 200 moves in a direction away from the conductive block 100, each rod-shaped structure 611 can pass through the corresponding avoidance hole 204 and contact the cantilever 350, applying a force to the cantilever 350 along the insulating movable member 200 toward the conductive block 100, thereby pushing the fourth end 352 of the cantilever to move in a direction close to the axis of the second channel 201 and causing the conductive elastic member 300 to store elastic potential energy. When the insulating movable member 200 moves in a direction close to the conductive block 100, the rod-shaped structure 611 gradually separates from the cantilever 350, causing the conductive elastic member 300 to release its elastic potential energy and drive the fourth end 352 of the cantilever to move in a direction away from the axis of the second channel 201.

[0105] Optionally, the second insulating fixing member 600 includes a second base 610 and a fourth joint portion 620. The second base 610 may include a columnar structure 612 and the aforementioned rod-shaped structure 611. The columnar structure 612 is connected to all rod-shaped structures 611 on one end away from the insulating movable member 200. The columnar structure 612 is also provided with a receiving hole (not marked in the figure) extending along the first direction. The receiving hole extends to the end face of the columnar structure 612 close to the end of the insulating movable member 200, and the receiving hole and the space defined by the multiple rod-shaped structures 611 together constitute a fourth channel 601. It can be understood that the fourth channel 601 is coaxially arranged with the second channel 201, and the fourth channel 601 is used to accommodate the fifth segment 250. Alternatively, the second base only includes multiple rod-shaped structures, but does not include a columnar structure (not shown in the figure). The fourth joint portion 620 is connected to an end of the second base 610 away from the insulating movable member 200 , and the fourth joint portion 620 is used to connect with the housing 10 so that the second insulating fixing member 600 is fixed on the housing 10 .

[0106] In this embodiment, it is preferred that the cantilever 350 and the insulating movable member 200 remain circumferentially relatively stationary to avoid circumferential relative movement of the cantilever 350 relative to the insulating movable member 200, which causes the cantilever 350 to be misaligned with the corresponding avoidance hole 204. An optional implementation method is to fix the second joint 340 and / or the third joint 360 to the insulating movable member 200, or to provide a limiting groove 241 extending through along the first direction on the outer peripheral surface of the fourth segment 240, and each second joint 340 is provided at a limiting groove 241. Another advantage of providing the limiting groove 241 and providing the cantilever 350 at the corresponding limiting groove 241 is that when assembling the conductive elastic member 300 and the insulating movable member 200, it is convenient to position the cantilever 350 to ensure that multiple cantilevers 350 correspond to multiple avoidance holes 204 one-to-one.

[0107] As can be seen from the above description, in this embodiment, if the elastic potential energy stored in the conductive elastic member 300 during deformation is released, it can only drive the fourth end 352 to move, and cannot drive the insulating movable member 200 to move in a direction close to the conductive block 100. In this case, please continue to refer to Figure 10. The adapter 20 also includes a reset elastic member 700. The reset elastic member 700 is arranged on the side of the insulating movable member 200 away from the conductive block 100. The reset elastic member 700 is, for example, a spring. The end of the reset elastic member 700 close to the insulating movable member 200 can be directly connected to the insulating movable member 200 or can be abutted against the insulating movable member 200. The end of the reset elastic member 700 close to the insulating movable member 200 is maintained relatively stationary with the conductive block 100 in any suitable manner. When the insulating movable member 200 moves in a direction away from the conductive block 100, the insulating movable member 200 drives the end of the reset elastic member 700 close to the conductive block 100 to move synchronously, so that the reset elastic member 700 stores elastic potential energy. When the restoring elastic member 700 releases its elastic potential energy, the restoring elastic member 700 drives the insulating movable member 200 to move in a direction close to the conductive block 100 .

[0108] Preferably, the resetting elastic member 700 is sleeved on the second insulating fixing member 600, and the end of the resetting elastic member 700 away from the insulating movable member 200 is connected to or abuts the fourth joint portion 620, so that the end of the resetting elastic member 700 away from the insulating movable member 200 remains relatively stationary with the conductive block 100. This arrangement allows the second insulating fixing member 600 to guide the movement of the end of the resetting elastic member 700 closer to the insulating movable member 200, causing it to move in the first direction, thereby preventing the resetting elastic member 700 from tilting and adversely affecting the movement of the insulating movable member 200 in the first direction.

[0109] Optionally, referring to Figure 10, the adapter 20 further includes a third insulating fixture 800, which is disposed on a side of the conductive block 100 close to the insulating movable member 200. The third insulating fixture 800 can be connected to the conductive block 100 (specifically, to the conductive block body 110) or to the housing 10, as long as it can remain relatively stationary with the conductive block 100. The third insulating fixture 800 is provided with a fifth channel 801 extending through along the first direction, and the fifth channel 801 is coaxially arranged with the second channel 201. The third insulating fixture 800 includes an insertion portion 810, which can be at least partially disposed in the second channel 201 and can also be separated from the insulating movable member 200. When the insertion portion 810 is at least partially disposed in the second channel 201, the insertion portion 810 is at least partially located in the fourth segment 240, and the cantilever 350 is located in the space enclosed by the insertion portion 810 and the fourth segment 240. The advantage of doing this is that when a temporary pacemaker equipped with the adapter device 20 provided in this embodiment is adapted to an epicardial temporary pacing electrode lead, the third insulating fixing 800 can physically isolate the third electrode 04 and the cantilever 350, thereby reducing the possibility of the third electrode 04 accidentally contacting the conductive elastic member 300 due to bending.

[0110] Optionally, the reset elastic member 700 is always in a compressed state. In other words, when the distance between the insulating movable member 200 and the conductive block 100 is minimized, the reset elastic member 700 also stores elastic potential energy. Furthermore, the dimension of the insertion portion 810 in the first direction is greater than the dimension of the fourth segment 240 in the first direction, so that when the distance between the insulating movable member 200 and the conductive block 100 is minimized, the end face of the insertion portion 810 away from the conductive block 100 can abut against the stepped surface 203 within the second channel 201, further preventing the third electrode 04 from accidentally contacting the conductive elastic member 300 due to bending.

[0111] Furthermore, a sealing structure (not shown) is provided on at least one of the surface of the end of the insertion portion 810 away from the conductive block 100 and the step surface 203. In this way, the surface of the end of the insertion portion 810 away from the conductive block 100 and the step surface 203 are sealed. The advantage of this is that when a temporary pacemaker equipped with the adapter device 20 provided in this embodiment is adapted to an epicardial temporary pacing electrode lead or a temporary pacing floating electrode lead, it is possible to avoid the situation where the cantilever 350 and the third electrode 04 (adapted to the epicardial temporary pacing electrode lead) or the fourth electrode 05 (adapted to the temporary pacing floating electrode lead) are electrically connected via the liquid due to conductive liquid such as saline or blood entering the second channel 201 or the fifth channel 801.

[0112] Furthermore, the outer side surface of the inserting portion 810 can be configured as a conical surface, with the distance from the conical surface to the axis of the second channel 201 gradually decreasing in a direction away from the conductive block 100. This design can better adapt to the state of the cantilever 350 when the inserting portion 810 is inserted into the second channel 201, and can minimize the application of force on the cantilever 350 that is perpendicular to the axis of the second channel 201 and in a direction away from the axis of the second channel 201, thereby freeing the cantilever 350 from force and extending its durability.

[0113] In summary, in this embodiment, the conductive block 100, the insulating movable part 200 and the avoidance hole 204 thereon, the rod-shaped structure 611 of the second insulating fixing part 600, and the reset elastic part 700 are indispensable components of the adapter device 20, while the third insulating fixing part 800 is a preferred structure provided by the adapter device 20 when adapting to the epicardial temporary pacing electrode lead or the temporary pacing floating electrode lead to avoid miscommunication between the electrode and the cantilever 350, and can be omitted.

[0114] Figures 14 and 15 are schematic diagrams of the structure of a temporary pacemaker equipped with the adapter device 20 provided in this embodiment. As shown in Figures 14 and 15, when not in use, the third insulating fixture 800 is partially inserted into the second channel 201.

[0115] When the temporary pacemaker of this embodiment is adapted to different electrode leads, the operation process of the various components of the adapter device 20 is described as follows.

[0116] When the temporary pacemaker is adapted to the standard IS-1 electrode lead, as shown in FIG16 , the first electrode 01 is controlled to be inserted into the second channel 201 through the first channel 101. The first electrode 01 is relatively thick and cannot pass through the position where the force transmission part 210 is located, so the free end of the first electrode 01 will abut against the force transmission part 210. After the free end of the first electrode 01 abuts against the force transmission part 210, the first electrode 01 applies a force along the axial direction of the second channel 201 (i.e., the first direction) and in the direction away from the conductive block 100 to the insulating movable part 200 through the force transmission part 210. As the first electrode 01 continues to advance, the insulating movable part 200 moves in the direction away from the conductive block 100 and separates from the third insulating fixed part 800, and allows the rod-shaped structure 611 to pass through the corresponding avoidance hole 204 and enter the second channel 201. The rod-shaped structure 611 then contacts the cantilever 350 and applies a force to the cantilever 350 along the insulating movable member 200 directed toward the conductive block 100, so that the fourth end 352 moves in a direction close to the axis of the second channel 201. The reset elastic member 700 stores elastic potential energy as the insulating movable member 200 moves. After the first electrode 01 contacts at least one cantilever 350, the pushing of the first electrode 01 can be stopped. At this time, the second electrode 02 is partially located in the first channel 101. The fastener 120 is then used to press against the second electrode 02 to lock the position of the standard IS-1 electrode wire. Subsequently, by energizing the electrical component 30, the temporary pacemaker can be used normally. To disconnect the temporary pacemaker from the standard IS-1 electrode lead, simply release the pressure of the fastener 120 on the second electrode 02 and remove the standard IS-1 electrode lead. The reset spring 700 automatically releases its elastic potential energy, driving the insulating movable member 200 toward the conductive block 100 until it resets and the third insulating fixed member 800 is partially inserted into the second channel 201. During this process, the rod-shaped structure 611 separates from the cantilever 350, and the conductive elastic member 300 releases its elastic potential energy, causing the fourth end 352 to move away from the second channel 201.

[0117] When the temporary pacemaker is adapted for an epicardial temporary pacing electrode lead, the third electrode 04 is controlled to be inserted into the second channel 201 via the first channel 101 and continuously advanced along the inclined surface 211 past the position of the force transmission portion 210 until it can no longer be pushed. At this point, a portion of the third electrode 04 remains within the first channel 101. The fastener 120 is then used to press against the third electrode 04 to lock the epicardial temporary pacing electrode lead. Ideally, the third electrode 04 maintains a straight configuration as shown in FIG17 throughout the operation. In this case, the insulating movable member 200 will substantially not push the insulating movable member 200 away from the conductive block 100. In some cases, the third electrode 04 may bend (as shown in FIG18), which may push the insulating movable member 200 to move a short distance, but this will generally not affect the normal use of the temporary pacemaker. Due to the physical isolation of the third insulating fixing member 800, contact between the third electrode 04 and the cantilever 352 is substantially prevented. When it is necessary to remove the temporary pacemaker and the epicardial temporary pacing electrode lead, it is only necessary to release the pressure of the fastener 120 on the second electrode 02 and pull out the epicardial temporary pacing electrode lead.

[0118] When the temporary pacemaker is adapted for a temporary pacing floating electrode, as shown in FIG19 , the fourth electrode 05 is controlled to be inserted into the fifth channel 801 via the first channel 101. Since the fourth electrode 05 is relatively short, it does not reach the location of the force transmission portion 210. As such, the fourth electrode 05 does not exert force on the insulating movable member 200, thereby preventing it from moving away from the conductive block 100. It is understood that when the fourth electrode 05 is unable to advance, it is partially located within the first channel 101. At this point, the fastener 120 is used to press against the fourth electrode 05, locking the temporary pacing floating electrode. Due to the physical isolation of the third insulating fixture 800, accidental contact between the fourth electrode 05 and the fourth electrode 05 is prevented. Furthermore, because the end surface of the third insulating fixture 800, facing away from the conductive block 100, is sealed to the stepped surface 203, conductive liquid entering the second channel 201, preventing the cantilever 350 from electrically connecting to the fourth electrode 05 through the conductive liquid, is prevented. When it is necessary to remove the temporary pacemaker and the epicardial temporary pacing electrode lead, it is only necessary to release the pressure of the fastener 120 on the second electrode 02 and pull out the temporary pacing floating electrode lead.

[0119] <Example 3>

[0120] The structure of the adapter device 20 provided in this embodiment is still as shown in FIG10 , with the difference being that when the cantilever 350 is subjected to a force perpendicular to the axis of the second channel 201 and in a direction away from the axis of the second channel 201, the fourth end 352 of the cantilever (i.e., the contact portion) moves in a direction away from the second channel 201, and the conductive elastic member 300 stores elastic potential energy. Conversely, when the force perpendicular to the axis of the second channel 201 and in a direction away from the axis of the second channel 201 is removed, the conductive elastic member 300 releases the elastic potential energy and drives the fourth end 352 of the cantilever to move in a direction close to the axis of the second channel 201, thereby switching to the initial state. That is, in this embodiment, the adapter device 20 shown in FIG13 is in a natural state, and when the adapter device 20 is not working, the conductive elastic member 300 is in the initial state shown in FIG12 and stores elastic potential energy.

[0121] Therefore, in this embodiment, the third insulating fixture 800 is a necessary structure of the adapter 20. The third insulating fixture 800 also applies a force perpendicular to the axis of the second channel 201 and away from the axis of the second channel 201 to the cantilever 350 as the conductive elastic member 300 moves with the insulating movable member 200 toward the conductive block 100. The third insulating fixture 800 also continuously applies a force perpendicular to the axis of the second channel 201 and away from the axis of the second channel 201 to the cantilever 350 when the distance between the insulating movable member 200 and the conductive block 100 is minimum. The second insulating fixture 600 and the avoidance hole 204 on the insulating movable member 200 are not necessary structures and can be omitted.

[0122] Thus, when the adapter device 20 provided in this embodiment is adapted to different electrode wires, the operations of the various components in the adapter device 20 are described as follows.

[0123] When the temporary pacemaker is adapted to a standard IS-1 electrode lead, as shown in FIG16 , the first electrode 01 is controlled to be inserted into the second channel 201 via the first channel 101. The first electrode 01 is relatively thick and cannot pass through the position where the force transmission portion 210 is located. Therefore, the free end of the first electrode 01 will abut against the force transmission portion 210. After the free end of the first electrode 01 abuts against the force transmission portion 210, the first electrode 01 applies a force along the axial direction of the second channel 201 (i.e., the first direction) and away from the conductive block 100 to the insulating movable member 200 through the force transmission portion 210. As the first electrode 01 continues to advance, the insulating movable member 200 moves in a direction away from the conductive block 100 and separates from the third insulating fixed member 800. As a result, the conductive elastic member 300 releases its elastic potential energy, causing the fourth end 352 of the cantilever to move in a direction close to the axis of the second channel 201, while the reset elastic member 700 stores elastic potential energy. After the first electrode 01 contacts the fourth end 352 of at least one cantilever, the first electrode 01 can be disengaged. At this point, the second electrode 02 is partially located within the first channel 101. The fastener 120 then presses against the second electrode 02 to lock the standard IS-1 electrode lead in place. By energizing the electrical assembly 30, the temporary pacemaker can be used normally. To disconnect the temporary pacemaker from the standard IS-1 electrode lead, simply release the pressure of the fastener 120 on the second electrode 02 and remove the standard IS-1 electrode lead. The resetting elastic member 700 automatically releases its elastic potential energy, driving the insulating movable member 200 toward the conductive block 100 until it resets, allowing the third insulating fixed member 800 to partially reinsert into the second channel 201. Simultaneously, the fourth end 352 of the cantilever, under the action of the third insulating fixed member 800, moves away from the axis of the second channel 201, allowing the conductive elastic member 300 to store elastic potential energy.

[0124] When the temporary pacemaker is adapted for an epicardial temporary pacing electrode lead, the third electrode 04 is controlled to be inserted into the second channel 201 via the first channel 101 and continuously advanced along the inclined surface 211 past the position of the force transmission portion 210 until it can no longer be pushed. At this point, a portion of the third electrode 04 remains within the first channel 101. The fastener 120 is then used to press against the third electrode 04 to lock the epicardial temporary pacing electrode lead. Ideally, the third electrode 04 maintains a straight configuration as shown in FIG17 throughout the operation. In this case, the insulating movable member 200 will substantially not push the insulating movable member 200 away from the conductive block 100. In some cases, the third electrode 04 may bend (as shown in FIG18), which may push the insulating movable member 200 to move a short distance, but this will generally not affect the normal use of the temporary pacemaker. Due to the physical isolation of the third insulating fixing member 800, contact between the third electrode 04 and the cantilever 352 is substantially prevented. When it is necessary to remove the temporary pacemaker and the epicardial temporary pacing electrode lead, it is only necessary to release the pressure of the fastener 120 on the second electrode 02 and pull out the epicardial temporary pacing electrode lead.

[0125] When the temporary pacemaker is adapted for a temporary pacing floating electrode, as shown in FIG19 , the fourth electrode 05 is controlled to be inserted into the fifth channel 801 via the first channel 101. Since the fourth electrode 05 is relatively short, it does not enter the second channel, located in the portion of the fifth channel 801 away from the conductive block 100, and thus does not contact the force transmission portion 210. Thus, the fourth electrode 05 does not push the insulating movable member 200 away from the conductive block 100. It can be understood that when the fourth electrode 05 cannot be advanced further, it is partially located within the first channel 101. At this point, the fastener 120 is used to press against the fourth electrode 05, locking the temporary pacing floating electrode. Due to the physical isolation of the third insulating fixture 800, accidental contact between the fourth electrode 05 and the fourth electrode 05 is prevented. Furthermore, because the end surface of the third insulating fixture 800 away from the conductive block 100 is sealed to the stepped surface 203, conductive liquid entering the second channel 201 and causing electrical conduction between the cantilever 350 and the fourth electrode 05 through the conductive liquid is prevented. When it is necessary to remove the temporary pacemaker and the epicardial temporary pacing electrode lead, it is only necessary to release the pressure of the fastener 120 on the second electrode 02 and pull out the temporary pacing floating electrode lead.
