Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a switching device for electrode wires and a temporary pacemaker. Background Art

[0002] Temporary pacemakers are widely used, mainly for the following three types of 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, removal of permanent pacemaker infection, 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 unknown, 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 waiting for a replacement pacemaker to be implanted.

[0006] The use of temporary pacemakers can not only prevent adverse events due to bradycardia in patients 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 wires that work more stably and reliably, which is not conducive to doctors choosing different measures for prevention, treatment or transition according to the actual situation of the patient.

[0067] One of the purposes of the utility model is to provide an electrode lead adapter, which can simultaneously adapt to a variety of electrode leads including a standard IS-1 electrode lead, a temporary pacing floating electrode lead, and an epicardial temporary pacing electrode lead. Therefore, when the adapter is used to be set on a temporary pacemaker, the temporary pacemaker can be suitable for different electrode leads, effectively expanding the indications and adaptation scenarios of a single temporary pacemaker.

[0068] The second object of the present utility model is to provide a temporary pacemaker equipped with the switching device of the aforementioned electrode wire.

[0069] In order to make the purpose, advantages and features of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0070] In order to facilitate understanding of the content of the present invention, firstly, 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.

[0071] Please refer to Figure 4 and Fig.14 The temporary pacemaker includes a housing 10, an adapter 20, an electrical component 30 and a wire 40. The adapter 20 and the electrical component 30 are both arranged on the housing 10, and the adapter 20 and the electrical component 30 are electrically connected through the wire 40. The electrical component 30 includes a wireless communication module, such as a Bluetooth communication module, a radio frequency communication module, a WIFI module, etc., which plays the role of pacing, sensing, heart rate response, etc., and plays the role of adjusting the operating parameters of the pacemaker during the operation of the temporary pacemaker.

[0072] Please refer to Figure 6 and Fig.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 axial direction of the standard IS-1 electrode lead, and the first electrode 01 and the second electrode 02 both extend along the axial direction of the standard IS-1 electrode lead, and 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 the temporary pacemaker through the adapter 20, the first electrode 01 and the second electrode 02 should be electrically connected to the electrical component 30 on the temporary pacemaker through the adapter 20.

[0073] Please refer to Figure 7 , Figure 8 , Fig.17 and Fig.18 The epicardial temporary pacing electrode lead includes an electrode, which is called the third electrode 04. The third electrode 04 is longer and thinner than the two electrodes of the standard IS-1 electrode lead. When the epicardial temporary pacing electrode lead is connected to the temporary pacemaker through the switching device 20, the third electrode 04 is electrically connected to the electrical component 30 through the switching device 20.

[0074] Please refer to Fig. 9 and Fig.19 The temporary pacing floating electrode includes an electrode, which is called the fourth electrode 05. The fourth electrode 05 is shorter and thicker than the first electrode 01 of the standard IS-1 electrode lead. When the temporary pacing floating electrode lead is connected to the temporary pacemaker through the adapter 20, the fourth electrode 05 is electrically connected to the electrical component 30 through the adapter 20.

[0075] Next, the structure of the switching device 20 will be introduced in detail.

[0076] Figure 1 and Fig.10 FIG. 2 shows an exploded schematic diagram of the adapter 20 provided in the embodiment of the utility model. Figure 1 and Fig.10 , the adapter 20 includes a conductive block 100, an insulating movable member 200 and a conductive elastic member 300, wherein 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 along the first direction. The insulating movable member 200 can move relative to the conductive block 100 along the first direction to approach or move away from the conductive block 100. The conductive elastic member 300 is connected to the insulating movable member 200 and moves at least partially with the insulating movable member 200. The conductive elastic member 300 also includes a contact portion (not marked in the figure). The adapter 20 is configured such that 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; 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.

[0077] Please refer to Figure 5 , Figure 6 , Fig.16 and Fig.17 When the adapter 20 is disposed on the housing 10, the conductive block 100 is fixedly connected to the housing 10, and the insulating movable member 200 can move along the 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 separated 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.

[0078] The temporary pacemaker equipped with the switching device 20 can be adapted to the standard IS-1 electrode lead. Figure 6 and Fig.16 As shown, the first electrode 01 of the standard IS-1 electrode wire 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, so that electrical conduction between the second electrode 02 and the electrical component 30 is achieved through the conductive block 100 and the first wire 41.

[0079] The temporary pacemaker equipped with the switching device 20 can also be adapted to the epicardial temporary pacing electrode lead. Figure 7 , Figure 8 , Fig.17 and Fig.18 , a part of the third electrode 04 is inserted into the second channel 201, and the other part is retained in the first channel 101. In this process, since the third electrode 04 is thin, it does not contact the inner surface of the second channel 201 or the contact force is very small, so the third electrode 04 basically does not push the insulating moving member 200 to move in the direction away from the conductive block 100, so that the contact part basically does not move in the direction close to the second channel 201, and does not contact the third electrode 04, while the third electrode 04 partially contacts the conductive block 100, and realizes electrical conduction with the electrical component 30 through the conductive block 100 and the first wire 41.

[0080] The temporary pacemaker equipped with the switching device 20 can also be adapted to the temporary pacing floating electrode lead. Fig. 9 and Fig.19 , a part of the fourth electrode 05 is inserted into the second channel 201, and the other part is in contact with the conductive block 100. In this process, since the fourth electrode 05 is relatively short, according to the specific configuration of the switching device 20, it will not push the insulating moving member 200 to move in a direction away from the conductive block 100, or although it will push the insulating moving 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.

[0081] Therefore, the temporary pacemaker equipped with the adapter 20 can be adapted to different electrode wires to expand the indications and application scenarios of a single temporary pacemaker, which is helpful for doctors to choose appropriate treatment methods according to the patient's specific situation and improve the treatment effect.

[0082] 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 autonomously move in a direction close to the axis of the second channel 201, and the situation that the conductive elastic member 300 at least partially moves with the insulating movable member 200 and enables the contact portion to autonomously move in a direction close to the axis of the second channel 201 with the help of other components. The situation of moving in the direction; “when the insulating movable member 200 moves in the direction close to the conductive block 100, the contact portion can move in the 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, so that the contact portion autonomously moves in the direction away from the axis of the second channel 201, and the situation that the conductive elastic member 300 at least partially moves with the insulating movable member 200, and the contact portion moves in the direction away from the axis of the second channel 201 with the help of other components.

[0083] Optionally, in the embodiment of the utility model, the conductive block 100 is further provided with a first channel 101 extending through the 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 the 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 the 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 the temporary pacing floating 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.

[0084] The configuration of the adapter 200 is introduced below through a specific embodiment. It should be noted that the adapter 200 is introduced below only in the form of enumeration, and it is impossible to exhaust all possible configurations of the adapter 200, so it should not constitute an improper limitation on the present invention.

[0085] <Example 1>

[0086] Please refer to Figure 1In 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 shell 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 100, 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 such as Figure 1 The groove structure shown may also be a through hole (not shown in the figure).

[0087] Please refer to Figure 2 and Figure 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 .

[0088] At least one force transmission part 210 extending along a third direction may be formed on the inner surface of the second channel 201, and the third direction is perpendicular to the first direction. Preferably, there are multiple force transmission parts 210, and the multiple force transmission parts 210 are arranged at equal intervals along the circumference of the second channel 201. It can be understood that the area surrounded by the multiple force transmission parts 210 is a part of the second channel 201. In this embodiment, the radial dimension of the area surrounded by the multiple force transmission parts 210 in the second channel 201 is equivalent to the radial dimension of the first electrode 01 of the standard IS-1 electrode lead, so that the first electrode 01 can pass through the position where the force transmission part 210 is located, but the two are in contact with each other and there is an interaction force. In addition, the radial dimension of the area surrounded by the multiple force transmission parts 210 in the second channel 201 should be larger than the outer diameter of the third electrode 04 of the epicardial temporary pacing electrode lead, and smaller than the outer diameter of the fourth electrode 05 of the temporary pacing floating electrode lead.

[0089] When the adapter 20 is adapted to the standard IS-1 electrode wire, the force transmission part 210 serves to transmit the force to drive the insulating movable member 200 to move in the direction away from the conductive block 100. Specifically, when the first electrode 01 of the standard IS-1 electrode wire 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 part 210 is located, the side wall of the first electrode 01 is in close contact with the force transmission part 210, and there is an interaction force between the two. In this way, during the advancement of the first electrode 01, the force transmission part 210 can be applied 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 the number of force transmission parts 210, the more balanced the force on the insulating movable member 200 in the circumferential direction of the second channel 201, and the more conducive to the stable movement of the insulating movable member 200 along the first direction, but when the number of force transmission parts 210 is too large, it is not conducive to the first electrode 01 passing through the position where the force transmission part 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.

[0090] Preferably, if Figure 2 As shown, the force transmission part 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 the 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 passes through the position where the force transmission part 210 is located, and the third electrode 04 is prevented from bending as much as possible, thereby reducing the situation where the third electrode 04 applies a force to the insulating movable member 200 through the force transmission part 210 as much as possible, thereby reducing the possibility that the contact part of the conductive elastic member 300 moves in the direction close to the axis of the second channel 201 and contacts the third electrode 04 due to the insulating movable member 200 moving in the direction away from the conductive block 100.

[0091] In this embodiment, the force transmission part 210 is arranged on the side of the contact part of the conductive elastic member 300 close to the conductive block 100. The purpose of this is to prevent the conductive elastic member 300 from contacting the fourth electrode 05 when adapting the temporary pacing floating insulated electrode wire.

[0092] When the adapter 20 is adapted to different electrode conductors, the relative relationship between the force transmission portion 210 and the corresponding electrode will be described in detail later.

[0093] Optionally, to further improve the stability of the insulating moving member 200 moving along the first direction, please refer to Figure 2 and Figure 3, a first guide portion 220 extending along a 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, and 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.

[0094] Please refer back to Figure 1 In this embodiment, the conductive elastic member 300 is a slender structure extending along the first direction, such as a filamentary structure. It should be noted that the conductive elastic member 300 extending along the first direction does not necessarily mean that the conductive elastic member 300 must be a straight line configuration, and it can also be a partially bent or curved structure, as long as the conductive elastic member 300 has two opposite ends in the first direction.

[0095] The two opposite ends of the conductive elastic member 300 in the first direction are respectively referred to as the first end 301 and the second end 302, wherein the first end 301 of the conductive elastic member is closer to the conductive block 100 than the second end 302 of the conductive elastic member. 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 relatively still with the conductive block 100. The contact portion is located between the first end 301 and the second end 302.

[0096] 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 in a direction away from the conductive block 100, the conductive elastic member 300 switches from the initial state to the deformed state.

[0097] 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 generates a bending deformation toward the axis of the second channel 201, and drives the contact portion to move in a direction close to the axis of the second channel 201, and the conductive elastic member 300 stores elastic potential energy. When the conductive elastic member 300 releases the elastic potential energy, the conductive elastic member 300 switches from the deformed state to the initial state, and causes the contact portion to move in a direction away from the axis of the second channel 201, and drives the insulating movable member 200 to move in a direction close to the conductive block 100.

[0098] In order to ensure that the portion of the conductive elastic member 300 between the first end 301 and the second end 302 is bent and deformed toward the axis of the second channel 201 during the process of the first end 301 of the conductive elastic member moving along with the insulating movable member 200 in a direction away from the conductive block 100, a designated area of ​​the conductive elastic member 300 is preliminarily formed into an arc when preparing the conductive elastic member 300, and 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. In this way, 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 conductive elastic member 300 can be further bent toward the axis of the second channel 201 under the guidance of the arc. In this way, the conductive elastic member 300 may include a first segment 310, a second segment 320 and a third segment 330 connected in sequence along a first direction, wherein the first segment 310 and the third segment 330 may both be in a straight line configuration, and the area where the second segment 320 is located is pre-bent into an arc as a designated area, so that the convex side of the second segment 320 at least partially constitutes a contact portion. During assembly, the end of the first segment 310 away from the second segment 320 is used as the first end 301 of the conductive elastic member to be connected to the insulating movable member 200, and accordingly, the end of the third segment 330 away from the second segment 320 is used as the second end 302 of the conductive elastic member, and the second segment 320 is located on the side of the force transmission part 210 away from the conductive block 100, so that the contact portion is located on the side of the force transmission part 210 away from the conductive block 100.

[0099] Preferably, the cross section of the conductive elastic member 300 is specially designed in this embodiment so that the rigidity of the second segment 320 is smaller than that of the first segment 310 and the third segment 330, and the second segment 320 is more easily deformed. In one solution, the cross section of the first segment 310, the cross section of the second segment 320, and the cross section of the third segment 330 are the same, but the cross section of the second segment 320 has the smallest area.

[0100] Alternatively, only the cross section of the second segment 320 is specially designed so that the second segment 320 is easily bent toward the axis of the second channel 210. Specifically, the size of the cross section of the second segment 320 in the radial direction of the arc structure is d1, and the size of the cross section of the second segment 320 in the axial direction of the arc structure is d2, and d1 is smaller than d2. The shape of the cross section of the second segment 320 can be any one of an ellipse, a rectangle, or a waist shape.

[0101] The number of the conductive elastic member 300 is at least one, preferably multiple, and the multiple conductive elastic members 300 are arranged at intervals 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 through the second wire 50. In other words, the multiple conductive elastic members 300 are arranged in parallel. The advantage of such an arrangement is that when the adapter 20 is adapted to the standard IS-1 electrode wire, there are multiple conductive elastic members 300 on 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, the electrical conduction between the first electrode 01 and the electrical component 30 can be achieved, thereby improving the success rate of the adapter 20 when adapting to the standard IS-1 electrode wire.

[0102] 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 engaging hole 202, which may be a blind hole, and the number of the first engaging holes 202 is not less than the number of the conductive elastic members 300. Preferably, the number of the first engaging holes 202 is equal to the number of the conductive elastic members 300, and the first engaging holes 202 are arranged one-to-one with the conductive elastic members 300. The first end 301 of each conductive elastic member is inserted into the corresponding first engaging hole 202, and the insulating movable member 200 and the first end 301 of the conductive elastic member are kept relatively still by any suitable method, and the optional methods include but are not limited to gluing, interference fit, etc.

[0103] Optionally, please continue to refer to Figure 1The adapter 20 also includes a first insulating fixing member 400, which is arranged on a 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 still with the conductive block 100. The first insulating fixing member 100 is provided with a third channel 401 extending along the first direction, and the third channel 401 at least extends to the surface of one end of the first insulating fixing member 100 close to the insulating movable member 200, and the third channel 401 is correspondingly arranged with the second channel 201, for example, coaxially arranged. A guide hole 402 as a through hole is also opened on the side wall of the first insulating fixing member 100 relative to the first direction, and the guide hole 402 is connected to the third channel 401. The number of the guide holes 402 is equal to the number of the conductive elastic members 300, and each guide hole 402 is arranged corresponding to a conductive elastic member 300. In other words, when the number of the conductive elastic member 300 is one, the number of the guide hole 402 is also one, and it is aligned with the conductive elastic member 300 in the circumferential direction of the second channel 201; when the number of the conductive elastic member 300 is multiple, the number of the guide hole 402 is also multiple, and the multiple guide holes 402 are arranged at intervals around the axis of the third channel 401, and each guide hole 402 is 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. In this way, when the second segment 320 is further bent and deformed, its convex side can be further bent toward the direction close to the axis of the second channel 201 under the constraint of the guide hole 402 to avoid deviation, and the bent and deformed second segment 320 can also contact the electrode to achieve electrical connection.

[0104] 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 and the conductive block 100 remain relatively stationary. Figure 1 The first insulating fixing member 400 includes a first base 410 and a first engaging portion 420, and the first base 410 is provided with the aforementioned third channel 401 and guide hole 402. The first engaging portion 420 is arranged on the outer side 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 along the first direction, and the number of the second engaging holes 421 is not less than the number of the conductive elastic members 300. Preferably, the number of the second engaging holes 421 is equal to the number of the conductive elastic members 300, and is arranged one-to-one with the conductive elastic members 300. Each conductive elastic member 300 is partially penetrated in the corresponding second engaging hole 421. The conductive elastic member 300 can be interference fit with the second engaging hole 421, or can be connected by an adhesive.

[0105] Further, in the case where there are multiple conductive elastic members 300, the adapter 20 preferably further includes a conductive bonding sheet 500. The conductive bonding sheet 500 is disposed on a side of the first insulating fixing member 400 away from the insulating movable member 200, and is electrically connected to all the conductive elastic members 300. At the same time, the second wire 42 connects the conductive bonding sheet 500 to the electrical component 30. In this way, the effect of connecting all the conductive elastic members 300 to the electrical component 30 can be achieved by using one second wire 42. It can be understood that the conductive bonding sheet 500 can be connected to the first insulating fixing member 400, or to the housing 10.

[0106] Figure 4 and Figure 5 The schematic diagram of the structure of a temporary pacemaker equipped with the adapter 20 provided in this embodiment is shown. The conductive block body 110 and the first insulating fixing member 400 of the conductive block 100 are fixedly connected to the housing 10, and the insulating movable member 200 cooperates with the second guide portion on the housing 10 through the first guide portion 220. When not in use, there is a gap between the insulating movable member 200 and the first insulating fixing member 400 to allow the insulating movable member 200 to move in a direction away from the conductive block 100.

[0107] 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.

[0108] When a temporary pacemaker is fitted with a standard IS-1 lead, Figure 6As shown, the first electrode 01 is controlled to be inserted into the second channel 201 through the first channel 101. After the free end of the first electrode 01 passes through the position of the force transmission part 210, the side wall of the first electrode 01 contacts the force transmission part 210, and the force transmission part 210 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. As the first electrode 01 continues to advance, the insulating movable member 200 moves in a direction away from the conductive block 100, and the contact part of the conductive elastic member 300 moves in a direction close to the axis of the second channel 201, until the first electrode 01 enters the third channel 401 and contacts with the contact part of at least one conductive elastic member 300. At this time, the adapter 20 is in a deformed state. At the same time, the second electrode 02 is partially located in the first channel 101. Then, the fastener 120 is pressed 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. When it is necessary to release the connection between the temporary pacemaker and the standard IS-1 electrode wire, it is only necessary to release the pressure of the fastener 120 on the second electrode 02 and pull out the standard IS-1 electrode wire. The conductive elastic member 300 will automatically release the elastic potential energy, driving the insulating movable member 200 to move in a direction close to the conductive block 100, so that the adapter 20 returns to its initial state.

[0109] When the temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, the third electrode 04 is controlled to be inserted into the second channel 201 through the first channel 101, and is continuously advanced along the inclined surface 211 through the area where the force transmission portion 210 is located until it cannot be pushed any further. During this process, the third electrode 04 may push the insulating movable member 200 to move in a direction away from the conductive block 100 when in contact with the inclined surface 211. 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, a portion of it still remains in the first channel 101. At this time, the third electrode 04 is pressed against by the fastener 120 to lock the epicardial temporary pacing electrode lead. Ideally, the third electrode 04 remains as follows during the entire operation. Figure 7 In the straight line configuration shown, in some cases, the third electrode 04 may be bent (eg Figure 8 When the temporary pacemaker and the epicardial temporary pacing electrode lead need to be released, 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.

[0110] When a temporary pacemaker is fitted with a temporary pacing floating electrode, Fig. 9As shown, 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 will not pass through the force transmission part 210, but abuts against the inclined surface 211. In this way, during the advancement of the fourth electrode 05, the fourth electrode 05 pushes the insulating movable member 200 to move in a direction away from the conductive block 100 through the inclined surface 211 until the fourth electrode 05 can no longer be advanced. Since the fourth electrode 05 will not pass through the force transmission part 210, it will not enter the third channel and will not contact the conductive elastic member 300. It can be understood that when the fourth electrode 05 cannot be advanced, the fourth electrode 05 is partially located in the first channel 101. At this time, the fastener 120 is used to press against the fourth electrode 05 to lock the temporary pacing floating electrode. When it is necessary to release 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.

[0111] <Example 2>

[0112] like Fig.10 As shown, the structure of the conductive block 100 in this embodiment can be the same as that in the first embodiment, and will not be described in detail here. The configurations of other components are different.

[0113] Optionally, please continue to refer to Fig.10 Combined with Fig.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.

[0114] Preferably, a force transmission part 210 is provided on the inner surface of the fifth segment 250. The specific structure of the force transmission part 210 can refer to the first embodiment and will not be described here. However, in this embodiment, the size of the area surrounded by the multiple force transmission parts 210 in the radial direction of the second channel 201 can be smaller than the outer diameter of the first electrode 01 of the standard IS-1 electrode wire, so that the free end of the first electrode 01 cannot pass through the position where the force transmission part 210 is located.

[0115] like Fig.10 , Fig.12 and Fig.13As shown, 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, and the fourth end 352 of the cantilever is a free end and constitutes a contact portion.

[0116] Optionally, there are multiple cantilevers 350, and the multiple cantilevers 350 are arranged at intervals 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 one 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 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 taken as an example that the number of cantilevers 350 is multiple.

[0117] For details, please refer to Fig.12 and Fig.13 , in this embodiment, Fig.12 FIG. 3 is a schematic diagram of the conductive elastic member 300 in a natural state. Fig.13 FIG. 1 is a schematic diagram showing a cantilever 350 of the conductive elastic member 300 being subjected to a force in a first direction directed from the insulating movable member 200 to the conductive block 100. Fig.13 In the embodiment, the conductive elastic member 300 stores elastic potential energy. Fig.12 In the embodiment, the distance between the fourth end 352 and the axis of the second channel 210 is L1. Fig.13, the distance from the fourth end 352 of the cantilever to the axis of the second channel 210 is L2, and L1 is greater than L2. That is, when the conductive elastic member 300 is subjected to a force directed toward the conductive block 100 along the insulating movable member 200, the fourth end 352 of the cantilever moves in a direction close to the axis of the second channel 201, and the conductive elastic member 300 stores elastic potential energy, and when the conductive elastic member 300 releases 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 form 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.

[0118] Based on the configuration of the conductive elastic member 300, please refer to Fig.11 The joint wall is provided with a shunting hole 204 extending through the first direction, and the number of the shunting holes 204 is equal to the number of the cantilevers 350, that is, a plurality of shunting holes 204 and a plurality of cantilevers 350 are arranged one by one. Please return to reference Fig.10 The adapter 20 further includes a second insulating fixture 600, which is disposed on a side of the fourth segment 240 away from the conductive block 100 and is used to be fixed to the housing 10 to remain relatively stationary with the conductive block 100. The second insulating fixture 600 includes a rod-shaped structure 611 extending along the first direction, and the number of the rod-shaped structures 611 is equal to the number of the cantilevers 350, that is, a plurality of rod-shaped structures 611. The plurality of rod-shaped structures 611 are disposed in one-to-one correspondence with the plurality of cantilevers 350, and thus are also disposed in one-to-one correspondence with the plurality of avoidance holes 204.

[0119] 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, and apply a force to the cantilever 350 along the insulating movable member 200 pointing to the conductive block 100, so as to push the fourth end 352 of the cantilever to move in a direction close to the axis of the second channel 201, and make the conductive elastic member 300 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, the conductive elastic member 300 releases elastic potential energy, and drives the fourth end 352 of the cantilever to move in a direction away from the axis of the second channel 201.

[0120] Optionally, the second insulating fixing member 600 includes a second base 610 and a fourth joint 620, and the second base 610 may include a columnar structure 612 and the aforementioned rod-shaped structure 611, and 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, and the receiving hole extends to the end surface of the columnar structure 612 close to the insulating movable member 200, and the receiving hole and the space defined by the plurality of rod-shaped structures 611 together constitute the 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 a plurality of 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 be connected to the housing 10 so that the second insulating fixing member 600 is fixed on the housing 10 .

[0121] In this embodiment, it is preferred that the cantilever 350 and the insulating movable member 200 remain relatively stationary in the circumferential direction to avoid the cantilever 350 from moving relative to the insulating movable member 200 in the circumferential direction, causing the cantilever 350 to be misaligned with the corresponding avoidance hole 204. An optional implementation method is to fix the second joint portion 340 and / or the third joint portion 360 to the insulating movable member 200, or to provide a limiting groove 241 extending through the first direction on the outer circumferential surface of the fourth segment 240, and each second joint portion 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 by one.

[0122] From the above description, it can be known that 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, but 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 Fig.10The adapter 20 further includes a resetting elastic member 700, which is disposed on a side of the insulating movable member 200 away from the conductive block 100. The resetting elastic member 700 is, for example, a spring. The end of the resetting elastic member 700 close to the insulating movable member 200 may be directly connected to the insulating movable member 200, or may be in contact with the insulating movable member 200. The end of the resetting elastic member 700 away from the insulating movable member 200 is kept relatively still 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 resetting elastic member 700 close to the conductive block 100 to move synchronously, so that the resetting elastic member 700 stores elastic potential energy. When the resetting elastic member 700 releases the elastic potential energy, the resetting elastic member 700 drives the insulating movable member 200 to move in a direction close to the conductive block 100.

[0123] 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 against the fourth joint portion 620, so that the end of the resetting elastic member 700 away from the insulating movable member 200 remains relatively still with the conductive block 100. In this arrangement, the second insulating fixing member 600 can be used to guide the movement of the end of the resetting elastic member 700 close to the insulating movable member 200, so that it moves along the first direction, thereby preventing the resetting elastic member 700 from tilting and causing an adverse effect on the movement of the insulating movable member 200 along the first direction.

[0124] Optionally, please continue to refer to Fig.10 , the adapter 20 also includes a third insulating fixing member 800, which is arranged on a side of the conductive block 100 close to the insulating movable member 200. The third insulating fixing member 300 can be connected to the conductive block 100 (specifically connected to the conductive block 110), or can be connected to the housing 10, as long as it can remain relatively still with the conductive block 100. The third insulating fixing member 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 fixing member 800 includes an insertion portion 810, which can be at least partially arranged in the second channel 201, and the insertion portion 810 can also be separated from the insulating movable member 200. When the insertion portion 810 is at least partially arranged 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.

[0125] 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 the smallest, the reset elastic member 700 also stores elastic potential energy. In addition, the size of the insertion portion 810 in the first direction is greater than the size 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 the smallest, the end face of the insertion portion 810 away from the conductive block 100 can abut against the step surface 203 in the second channel 201, further avoiding the possibility of the third electrode 04 accidentally contacting the conductive elastic member 300 due to bending.

[0126] Furthermore, a sealing structure (not shown in the figure) is also 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 is sealed and connected to the step surface 203. The advantage of this is that when a temporary pacemaker equipped with the adapter 20 provided in this embodiment is adapted to an epicardial temporary pacing electrode lead or a temporary pacing floating electrode lead, it can be avoided that the cantilever 350 is electrically connected to 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) via liquid due to the conductive liquid such as saline, blood, etc. entering the second channel 201 or the fifth channel 801.

[0127] In addition, the outer side surface of the insertion portion 810 can be configured as a conical surface, and the distance from the conical surface to the axis of the second channel 201 gradually decreases in the direction away from the conductive block 100. Such a design can better adapt to the state of the cantilever 350 when the insertion portion 810 is inserted into the second channel 201, and avoid applying a force perpendicular to the axis of the second channel 210 and in a direction away from the axis of the second channel 201 to the cantilever 350 as much as possible, so that the cantilever 350 is not subjected to force, thereby extending its durability.

[0128] 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 the epicardial temporary pacing electrode lead or the temporary pacing floating electrode lead to avoid misconduction between the electrode and the cantilever 350, and can be omitted.

[0129] Fig.14 and Fig.15 FIG. 2 is a schematic diagram of the structure of a temporary pacemaker equipped with the switching device 20 provided in this embodiment. Fig.14 and Fig.15As shown, when not in use, the third insulating fixture 800 is partially inserted into the second channel 201 .

[0130] When the temporary pacemaker of this embodiment is adapted to different electrode leads, the operation process of each component of the switching device 20 is described as follows.

[0131] When a temporary pacemaker is fitted with a standard IS-1 lead, Fig.16 As shown, 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 away from the conductive block 100 to the insulating movable member 200 through the force transmission part 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 fixing member 800, and the rod-shaped structure 611 passes through the corresponding avoidance hole 204 and enters the second channel 201. Subsequently, the rod-shaped structure 611 contacts the cantilever 350 and applies a force to the cantilever 350 along the insulating movable member 200 pointing to the conductive block 100, so that the fourth end 352 moves in a direction close to the axis of the second channel 201. The resetting 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 first electrode 01 can be stopped from being pushed, and at this time, the second electrode 02 is partially located in the first channel 101. Then, the second electrode 02 is pressed against by the fastener 120 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. When the temporary pacemaker needs to be disconnected from the standard IS-1 electrode wire, it is only necessary to release the pressure of the fastener 120 on the second electrode 02 and pull out the standard IS-1 electrode wire, and the resetting elastic member 700 will automatically release the elastic potential energy and drive the insulating movable member 200 to move in the direction close to the conductive block 100 until it is reset, and the third insulating fixing member 800 is partially inserted into the second channel 201. In this process, the rod-shaped structure 611 is separated from the cantilever 350, and the conductive elastic member 300 releases the elastic potential energy, so that the fourth end 352 moves in the direction away from the second channel 201.

[0132] When the temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, the third electrode 04 is controlled to be inserted into the second channel 201 through the first channel 101, and is continuously pushed along the inclined surface 211 through the position where the force transmission part 210 is located until it cannot be pushed. At this time, a part of the third electrode 04 is still left in the first channel 101. Then, the third electrode 04 is pressed against by the fastener 120 to lock the epicardial temporary pacing electrode lead. Ideally, the third electrode 04 is kept as shown in the figure during the entire operation. Fig.17 In this case, the insulating moving member 200 will not push the insulating moving member 200 to move in a direction away from the conductive block 100. In some cases, the third electrode 04 may be bent (eg, Fig.18 As shown in the figure, it may push the insulating movable member 200 to move a short distance, but this basically does not affect the normal use of the temporary pacemaker. Due to the physical isolation of the third insulating fixing member 800, the third electrode 04 will basically not come into contact with the cantilever 352. When it is necessary to release the temporary pacemaker from 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.

[0133] When a temporary pacemaker is fitted with a temporary pacing floating electrode, Fig.19 As shown, the fourth electrode 05 is controlled to be inserted into the fifth channel 210 via the first channel 101. The fourth electrode 05 is shorter and will not reach the position of the force transmission part 210. In this way, the fourth electrode 05 will not apply a force to the insulating movable member 200, and will not push the insulating movable member 200 to move in a direction away from the conductive block 100. It can be understood that when the fourth electrode 05 cannot be pushed forward, the fourth electrode 05 is partially located in the first channel 101. At this time, the fastener 120 is used to press against the fourth electrode 05 to lock the temporary pacing floating electrode. Due to the physical isolation of the third insulating fixing member 800, there will be no accidental contact between the fourth electrode 05 and the fourth electrode 05. In addition, since the end face of the third insulating fixing member 800 away from the conductive block 100 is sealed and connected to the step surface 203, there will be no situation where the cantilever 350 is electrically connected to the fourth electrode 05 through the conductive liquid due to the conductive liquid entering the second channel 201. When it is necessary to release 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.

[0134] <Example 3>

[0135] The structure of the switching device 20 provided in this embodiment is still as follows Fig.10As shown, the difference is 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 cancelled, 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 to switch to the initial state. That is to say, in this embodiment, Fig.13 The switching device 20 shown is in a natural state, and when the switching device 20 is not working, the conductive elastic member 300 is in Fig.12 The initial state is shown, and elastic potential energy is stored.

[0136] Therefore, in this embodiment, the third insulating fixing member 800 is a necessary structure of the switching device 20, and the third insulating fixing member 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 when the conductive elastic member 300 follows the insulating movable member 200 in the process of approaching the conductive block 100, and the third insulating fixing member 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 the smallest. The avoidance hole 204 on the second insulating fixing member 600 and the insulating movable member 200 is not a necessary structure and can be omitted.

[0137] Thus, when the adapter device 20 provided in this embodiment is adapted to different electrode wires, the actions of the various components in the adapter device 20 are described as follows.

[0138] When a temporary pacemaker is fitted with a standard IS-1 lead, Fig.16As shown, 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. Therefore, 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 away from the conductive block 100 to the insulating movable member 200 through the force transmission part 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 elastic potential energy, so that the fourth end 352 of the cantilever moves in a direction close to the axis of the second channel 201, and 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 stopped from being pushed. At this time, the second electrode 02 is partially located in the first channel 101. Then, the second electrode 02 is pressed against by the fastener 120 to lock the position of the standard IS-1 electrode wire. By energizing the electrical component 30, the temporary pacemaker can be used normally. When the connection between the temporary pacemaker and the standard IS-1 electrode wire needs to be released, it is only necessary to release the pressure of the fastener 120 on the second electrode 02 and pull out the standard IS-1 electrode wire, and the reset elastic member 700 will automatically release the elastic potential energy and drive the insulating movable member 200 to move in the direction close to the conductive block 100 until it is reset, so that the third insulating fixed member 800 is partially inserted into the second channel 201 again, and at the same time, the fourth end 352 of the cantilever moves in the direction away from the axis of the second channel 201 under the action of the third insulating fixed member 800, and the conductive elastic member 300 stores elastic potential energy.

[0139] When the temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, the third electrode 04 is controlled to be inserted into the second channel 201 through the first channel 101, and is continuously pushed along the inclined surface 211 through the position where the force transmission part 210 is located until it cannot be pushed. At this time, a part of the third electrode 04 is still left in the first channel 101. Then, the third electrode 04 is pressed against by the fastener 120 to lock the epicardial temporary pacing electrode lead. Ideally, the third electrode 04 is kept as shown in the figure during the entire operation. Fig.17 In this case, the insulating moving member 200 will not push the insulating moving member 200 to move in a direction away from the conductive block 100. In some cases, the third electrode 04 may be bent (eg, Fig.18As shown in the figure, it may push the insulating movable member 200 to move a short distance, but this basically does not affect the normal use of the temporary pacemaker. Due to the physical isolation of the third insulating fixing member 800, the third electrode 04 will basically not come into contact with the cantilever 352. When it is necessary to release the temporary pacemaker from 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.

[0140] When a temporary pacemaker is fitted with a temporary pacing floating electrode, Fig.19 As shown, the fourth electrode 05 is controlled to be inserted into the fifth channel 801 via the first channel 101. The fourth electrode 05 is shorter and will not enter the second channel located in the part of the fifth channel 801 away from the conductive block 100, so it will not contact the force transmission part 210. In this way, the fourth electrode 05 will not push the insulating movable member 200 to move in the direction away from the conductive block 100. It can be understood that when the fourth electrode 05 cannot be further advanced, the fourth electrode 05 is partially located in the first channel 101. At this time, the fastener 120 is used to press against the fourth electrode 05 to lock the temporary pacing floating electrode. Due to the physical isolation of the third insulating fixing member 800, the fourth electrode 05 will not accidentally contact the fourth electrode 05. In addition, since the end surface of the third insulating fixing member 800 away from the conductive block 100 is sealed and connected to the step surface 203, the cantilever 350 will not be electrically connected to the fourth electrode 05 through the conductive liquid due to the conductive liquid entering the second channel 201. When it is necessary to release 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.
