Description

心脏电学信息标测电极 Cardiac electrical information mapping electrodes

技术领域 FIELD

[0001] 本发明涉及手术器械领域,具体而言,涉及一种心脏电学信息标测电极。 [0001] The present invention relates to the field of surgical instruments, particularly, to a cardiac electrical information mapping electrode.

背景技术 Background technique

[0002] 目前,在心脏电生理检查时,需要将标测电极放置在心脏特定的位置,心脏特定位置所产生的电信号被该处放置的标测电极所获取,然后标测电极将所获取的电信号传递给相应的检查设备。 [0002] Currently, when a cardiac electrophysiology, mapping electrodes need to be placed in a specific location of the heart, cardiac mapping electrode electrical signals generated by a particular location to be placed there acquired, and the acquired mapping electrode the electrical signals corresponding to the inspection apparatus. 一般的电生理检查,由于在检查的时候,心脏不同的位置,所放电极均是不一样的,需要在心脏的不同位置放置不同的标测电极,例如高右房电极、希氏束电极为4极电极,右心室电极一般是2极或者4极电极,冠状窦电极为10极电极等。 General electrophysiological examination, since the examination time, a different position of the heart, the discharge electrode are different, need to place a different mapping electrode at different locations of the heart, for example, high right atrial electrode bundle electrode electrode 4, the right ventricular electrode is typically 2 or 4-pole electrode, the electrode is a coronary sinus electrode 10 and the like.

[0003] 但是,每个电极均会产生成本,放置的电极越多,这就造成了电生理检查的费用越高;同时,由于要将不同的电极放置到心脏不同的位置,在进行放置手术的时候,由于人体的血管是与心脏连接的,标测电极穿过人体不同位置的动脉或者经脉,到达心脏的位置,因此要放置的电极越多,手术需要的时间也越长,而手术是在X光线下进行的,这样相当于增加了X光线的曝光时间,从而增加了X光线对人体的影响。 [0003] However, each electrode will produce cost more electrode placement, which resulted in higher electrophysiological examination fee; same time, because you want different electrode placed in a different location in the heart, placed during surgery time, because the body is a vessel connected to the heart, through the artery or mapping electrode positions different meridians of the human body, reaches the position of the heart, so the more the electrode is to be placed, the time required for surgery is also longer, and surgery is performed under X rays, this is equivalent to increasing the exposure time of the X ray, and X-rays to increase the effect on the human body.

[0041] 下面将结合本发明实施例中附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。 [0041] below in conjunction with the present invention illustrated in the drawings embodiments, the technical solutions in the embodiments will be apparent to the present invention, completely described, obviously, the described embodiments are merely part of embodiments of the present invention rather than all embodiments . 通常在此处附图中描述和示出的本发明实施例的组件可以以各种不同的配置来布置和设计。 Components of an embodiment of the present invention is generally described herein and illustrated in the drawings can be arranged and designed in a variety of different configurations. 因此,以下对在附图中提供的本发明的实施例的详细描述并非旨在限制要求保护的本发明的范围,而是仅仅表示本发明的选定实施例。 Accordingly, the following detailed description of the invention provided in the drawings embodiments is not intended to limit the scope of the invention claimed, but is merely representative of selected embodiments of the present invention. 基于本发明的实施例,本领域技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例,都属于本发明保护的范围。 Based on the embodiments of the present invention, all other embodiments of the present art in the art without creative efforts shall fall within the scope of the present invention.

[0042] 现在的在心脏电生理检查时,使用的心脏电学信息标测电极数量多,造成手术的成本高,手术时间长,增加了X光线的曝光时间,从而增加了X光线对人体的影响。 [0042] Now in the cardiac electrophysiology, cardiac electrical information mapping electrodes used quantity, high cost caused by surgery, surgery for a long time, increasing the exposure time and X-rays, thereby increasing the effect of X rays on the human body . 基于此,本申请提供了一种心脏电学信息标测电极,主要用在对希氏束和右心室电学信号的检测中,能够减少在心脏电生理检查时所使用的标测电极的数量,降低检查费用,同时减少手术时间,降低X光线的曝光时间,从而降低X光线对人体的影响。 Based on this, the present application provides a mapping of cardiac electrical information electrodes, mainly used in the detection of the right ventricle and the bundle of electrical signals, it is possible to reduce the number of mapping electrodes at the time of cardiac electrophysiology used to reduce inspection costs, while reducing the operation time, reducing the exposure time of the X ray, and X-rays to reduce the impact on the human body.

[0043] 参见图1所示,本发明实施例提供的心脏电学信息标测电极包括:导管101 ;所述导管101的一端设置有电极103,所述电极103与所述导管101共轴; [0043] Referring to FIG. 1, the embodiment of the present invention, an electrical cardiac mapping information provided by the electrodes comprising: a catheter 101; 101 end of the catheter is provided with an electrode 103, the electrode 103 and the catheter 101 coaxially;

[0044] 所述导管101的另一端设置有连接头104 ; [0044] The other end of the conduit 101 is provided with a connector 104;

[0045] 所述电极103有多个;多个所述电极103用于获取心脏不同位置的电信号。 The [0045] 103 with a plurality of electrodes; a plurality of electrodes 103 for acquiring an electrical signal at different locations of the heart.

[0046] 在具体实现的时候,在将心脏电学信息标测电极通过手术安置在人体中的时候,由于人体的心脏与血管是相通的,因此要使得导管101端部所设置的电极103沿着人体的血管(动脉或者静脉),到达预定的安装位置,为了有效的减少标测电极的数量,多个电极103所能够到达的位置一般都能够通过一条血管到达。 [0046] In the concrete implementation, the cardiac electrical information mapping electrode when positioned surgically in the body, because the human heart and blood vessels are interlinked, so that the electrode 103 to the conduit 101 is provided along the end portion human blood vessels (arteries or veins), reaches a predetermined mounting position, in order to effectively reduce the number of mapping electrodes, the plurality of electrodes 103 are generally able to reach a position can be reached through a blood vessel. 而在人体心脏、血管回路的构造中,希氏束和右心室是可以通过一条血管到达的,因此,本申请所提供的心脏电学信息标测电极主要应用在对希氏束和右心室电学信号的检测中,而在本申请所提供的心脏电学信息标测电极中,由于在导管上设置了多个电极103,不同的电极103的位置由于是不一样的,因此可以接触的心脏不同的位置,因此能够获取心脏不同位置的电信号,这样,只要控制好电极103之间的距离,就能够通过一根导管,分别检测到希氏束和右心室的电极,这样,减少了导管的用量,其一是降低了手术的成本,进而能够降低检查费用,其二是安装的导管少了,手术所使用的时间也相应的减少,减少人在X光下线的曝光时间,从而降低X光线对人体的影响。 In the configuration of the human heart, blood vessels circuit, the His bundle and right ventricle are reachable through a blood vessel, therefore, cardiac electrical information mapping electrode main application of the present application is provided to the bundle and right ventricular electrical signal detection of different cardiac, cardiac electrical information in mapping electrode provided herein, since a plurality of electrodes disposed on the catheter 103, the position of the electrode 103 is different because it is not the same, it is possible to position the contact , it is possible to obtain electrical signals of the heart in different positions, so long as control the distance between the electrodes 103, it is possible through a conduit, respectively, to the electrode bundle is detected and the right ventricle, thus, reducing the amount of the conduit, one is to reduce the cost of the operation, inspection costs can be reduced further, and the second conduit is less installation, operation time used correspondingly reduced, reducing the exposure time of the X-ray people offline, thereby reducing light on X affect the human body.

[0047] 考虑到能够让电极103能够检测到心脏不同位置的电信号,并且能够保证电极103能够将其所检测到的电信号传递给相应的检测设备,例如心电图测量仪,因此在导管内设置了相互不导通的多根导线105,每个电极103分别连接有不同的导线105。 [0047] Taking into account to allow the electrode 103 can detect the electrical signals of the heart in different locations, and to ensure that the electrode 103 can deliver an electrical signal to detect their respective detection equipment, e.g. electrocardiogram measurement instrument, thus disposed within the conduit each of the plurality of non-conducting wires 105, 103 are each connected to a different electrode wires 105.

[0048] 在具体实现的时候,可以在导管内设置空腔,将导线设置在空腔内,导线的一端穿过导管的侧壁,与电极103相连接。 [0048] In the concrete implementation, a cavity may be provided within the conduit, the wires disposed within the cavity, the side walls of the end of the wire through the catheter, and connected to the electrode 103. 导线的另一端在导管101内,沿着空腔到达连接头部位。 The other end of the wire within the catheter 101, along a portion of the cavity reaches the connection head. 需要注意的是,由于是要将电极103伸入到血管内部,因此为了防止血管内部的血液进入到导管101的空腔内,电极103与导管101的连接部位是密封的。 Note that, since the electrode be 103 extending into interior of the vessel, in order to prevent the interior of the blood vessel into the catheter cavity 101, conduit 103 and the electrode connecting portion 101 is sealed.

[0049] 除了通过设置在导管内的空腔来放置导线105之外,还可以直接使用制成导管的材料在多根导线之外浇筑制成导管整体,这样,导线105和导管101连接为一体,有利于手术过程中医生对整个导管的操控。 [0049] In addition to the cavity provided by the wire 105 is placed within the catheter may also be used as material of the catheter outside the plurality of wires pouring conduit integrally formed, so that the wire 105 and the conduit 101 is connected integrally It will help doctors during surgery manipulation of the entire catheter.

[0050] 连接头有两个作用: [0050] The connector has two functions:

[0051] 一个是将与其连接的导线所传递的电信号传递给相关的检测设备; [0051] a is connected thereto to transmit electrical signals transmitted by wire to the relevant test equipment;

[0052] 二是在手术的过程中,医生能够手持该连接头,通过转动与连接头相连接的导管,以调整导管101进入血管的方向、路径,使得电极103最终贴靠在心脏内的具体待测位置。 [0052] Second, in the course of the operation, the physician can handheld connector through the conduit and connector rotatably connected to the adjustment direction of the catheter into a blood vessel 101, the path, so that the electrode 103 rests final concrete within the heart position to be measured.

[0053] 一般情况下,导管与连接头是固定连接的,即在整体的标测电极制造的时候,将导管与连接头制作成一个整体,连接头远离导管的一端能够用来连接相关的检测设备,并将导线所传递到连接头的电学信息传递给相关的检测设备。 [0053] In general, the catheter connector is fixedly connected, i.e., when the entire mapping electrodes manufactured, and the catheter connector made into an integral connector end remote from the connecting conduit can be used to detect related device and transmitted to the wire connector information to the relevant electrical testing equipment. 针对每一个病人,所采用的标测电极都是一次性的。 For each patient, mapping electrodes used are disposable.

[0054] 另外,除了小孩和一些患有特殊心脏疾病的人之外,其他的人的心脏的大小都是类似的,但是依然会存在一定的差别,因此针对不同的人做检查的时候,具体使用的标测电极要根据最终对人体进行X光成像后,医生根据成像的结果再具体进行判断,因此为了增加心脏电学信息标测电极的可选择性(即不同的人,所使用的心脏电学信息标测电极上,电极103的位置或者电极103之间的距离可能不同),也为了使得连接头可以重复的进行使用,即进一步的降低检查的成本,不同的病人,只需要更换导管101即可,因此本申请所提供的心脏电学信息标测电极中,将导管101和连接头104可拆卸的连接。 [0054] In addition, in addition to a number of children and people with special heart disease, the size of other people's hearts are similar, but still there are some differences, so do check the times for different people, specifically mapping electrodes used according to the final X-ray imaging of the human body, particularly for doctors and then depending on the results of imaging, and therefore in order to increase the electric power information selectively cardiac mapping electrode (i.e., different people use electrical cardiac information on the mapping electrodes, the distance between the position of the electrode 103 or the electrode 103 may be different), but also so that the connector can be reused in order to be used, i.e., further reduce the cost of inspection, different patients, i.e., only need to replace the catheter 101 can, therefore cardiac mapping electrode electric power information provided in the present application, the catheter 101 and connector 104 detachable connection.

[0055] 在具体实现的时候,导管上远离电极103的一端设置有一限位台110 ;所述导管上套有连接套管111 ;该连接套管111能够被该限位台110挡住,使得连接套管111无法从导管101上远离电极103的一端滑出导管101。 [0055] In the concrete implementation, one end of the conduit remote from the upper electrode 103 is provided with a stopper 110; 111 sets a connecting sleeve on the catheter; the connecting sleeve 111 can be blocked by the stopper 110, so that the connection One end of the sleeve 111 remote from the electrode 103 can not slide out of the catheter 101 from the conduit 101. 在该连接套管内设置有内螺纹,在连接头104上设置有与该内螺纹相互配合的外螺纹,该连接套管能够通过内螺纹和外螺纹,可拆卸的连接在连接头104上。 Disposed within the internally threaded sleeve is connected, it is provided with an external thread cooperating with the inner thread on the connector 104, through the inner connecting sleeve and external threads, detachably connected to the connector 104.

[0056] 同时,在医生将导管置入人体的血管之后,需要转动导管来调整导管的位置,由于导管101本身是与连接头104可拆卸连接的,因此在医生转动导管的过程中,可能会导致导管101和连接头104之间进行转动,导管和连接头之间的转动会对医生的操作有一定的影响,为了消除这一影响,在导管上还形成有限位卡子,该限位卡子能够使得导管101和连接头104之间出现转动。 [0056] Meanwhile, the physician after the catheter into the body vessel, the catheter need to adjust the rotational position of the catheter, because the catheter 101 itself is connected to the head 104 of the detachable connection, rotation of the catheter so the doctor process, may be will cause the doctor to rotate the rotation between the catheter and between the catheter connector 101 and the operation connector 104 to a certain extent, in order to eliminate this effect, the tube is further formed in a limiting clamp, the clamp can be limiting such that rotation occurs between the catheter 101 and the connector 104.

[0057] 另外,还可以在该连接套管上设置外螺纹,在连接头104上设置于该外螺纹相互配合的内螺纹,同样的,该连接套管能够通过该内螺纹和外螺纹,可拆卸的连接在连接头104 上。 [0057] Further, an external thread may be provided on the connector sleeve, disposed on the external thread cooperating internal threads on the connector 104, the same, through the connection of the inner sleeve and external threads, may be detachably connected to the connector 104.

[0058] 另外,考虑到导线105是设置在导管101内的,导管101与连接头104可拆卸的连接,因此也需要将导线105与连接头104可拆卸的连接。 [0058] Further, considering the wire 105 is disposed within the conduit 101, the conduit 101 and the connector 104 is detachably connected, is also required to wire 105 and connector 104 detachable connection. 具体在实现的时候,在所述连接头104的内部设置有多个与所述导管101相通的凹槽106 ;每个凹槽106内均设置有连接插针107 ;每根所述导线105伸入一个所述凹槽106,与凹槽106内的所述连接插针107可拆卸的相连接。 Specifically, when implemented in the interior of the connection head 104 is provided with a plurality of said conduits communicating with the recess 106 101; 107 is provided with connecting pins each recess 106; each of said extension wire 105 into the recess 106 a, the inner recess 106 and the connection pin 107 is connected detachably.

[0059] 一般的,凹槽106的方向是朝向导管101所在的方向设置的,这样,可以方便导管内导线105与连接插针107的连接。 [0059] Typically, the direction of the groove 106 is located toward the conduit 101 is provided, so that wire 105 can be easily connected to the connector pins 107 of the inner catheter. 同时,凹槽106和连接插针107的数量一般会多于导线105的数量,例如将将接线插针设置为14个,一般情况而言,导线的数量都是在10根以内的。 Meanwhile, the number of grooves 106 and pins 107 are typically connected to more than the number of wires 105, for example, to the terminal pin 14, generally speaking, the number of wires is less than 10 in. 不仅可以将本申请所提供的导管101与连接头,还可以将用于测量其他位置电学信息的标测电极的导管安装在该连接头104上。 Mapping electrode catheter may not only be provided herein with a conduit connector 101, it may also be used to measure other electrical position information attached to the connector 104. 不管导管101内的导线105有多少根,保证每一根导线均能够连接到连接头104上。 Regardless of the wire in the conduit root number 101,105, both to ensure that each wire can be connected to the connector 104.

[0060] 在将连接插针107和导线105连接的时候,为了方便两者的连接,在导线105伸入到凹槽106的一端还连接有插接件108,所述连接插针107可以插入所述插接件108中。 [0060] In the connecting pins 107 and 105 when the lead wire is connected, in order to facilitate the connection between the two, to one end of the wire 105 projecting into the groove 106 is also connected with a connector 108, the connection pins 107 can be inserted the plug member 108.

[0061] 另外还可以将插接件108设置在凹槽106内,同时在导线105上设置连接插针107,或者直接将导线105作为连接插针107来使用,同样也能够实现导线105与连接头104之间的可拆卸连接。 [0061] Also the plug member 108 may be disposed in the recess 106, while conductor 105 is provided on the connecting pins 107, or directly to the wire 105 as a connection pin 107 is used, the same can be achieved and the connecting wire 105 the detachable connection between the head 104.

[0062] 另外,由于在手术的过程中,医生需要不断的转动导管以调整导管的走向、电极103的位置,而人体的血管并不是一根只管,而是具有各种岔路和弧度的,因此,导管必须是具备一定柔韧性的柔性导管,该柔性导管能够在医生的控制下,在人体血管内,沿着血管的路径弯折,这样,医生通过不断的转动导管或者调整导管的位置,能够将导管上的电极103送至预设的检查位置。 [0062] Further, since in the course of surgery, doctors need to constantly adjust the rotation of the catheter to position the catheter, electrode 103, and the body's vascular not just one, but a fork and having various curvature, so , the catheter must be a certain flexibility of the flexible conduit, the flexible conduit can be under the control of a doctor, in the blood vessels, the blood vessel is bent along the path, so that, through continuous rotation of the doctor to adjust the position of the catheter or the catheter can be the electrode 103 on the catheter to the predetermined inspection position.

[0063] 而柔性导管的表面为光滑的,即导管表面不具备任何的突起、螺纹、倒刺、锈斑等,只有这样,才能够保证导管在人体血管内前进的时候,减小导管对人体血管的损伤。 [0063] the smooth surface of the flexible conduit, i.e., the surface of the catheter does not have any projections, threads, barbs, rust, etc., the only way to ensure that when the catheter is advanced in the blood vessels, reducing blood vessels catheter damage.

[0064]另外,柔性导管在转动的时候,由于本身是比较软的,因此可能从导管101与连接头104的位置弯折,同时,由于柔性导管容易产生形变,因此为了保证导管能够方便的安装到连接头104上,也为了柔性导管能够更好的为医生所操控,在导管101和连接头104之间,还设置有标志管109 ;该标志管109为刚性导管,刚性导管由于其本身硬度比较大,因此能够更好的与连接头104相连接,同时也能够更容易被医生所操控。 [0064] Further, the flexible conduit in rotation, because of itself is relatively soft, and therefore may be bent from the position of the catheter 101 and the connector 104, at the same time, since the easily deformable flexible duct, so in order to ensure that the catheter can be easily installed connected to the head 104, and to a flexible conduit for the doctor to be able to better control, between the catheter 101 and the connector 104, tube 109 is also provided with a flag; this flag is rigid conduit tube 109, due to its own stiffness rigid conduit is relatively large, it can be better connected to the connector 104, but also can be more easily manipulated by the doctor. 所述电极设置所述导管远离所述标志管的一端。 The electrode is disposed remote from said one end of said catheter tube flag. 另外,由于导管本身是要伸入到血管中的,因此表面要保持光滑,而为了能够让医生能够识别出不同型号的导管,因此在标志管109上还可以刻有或者印有导管的型号标识等,用于医生对导管更好的识别。 Further, since the pipe itself is getting into the blood vessel, to maintain the smooth surface and therefore, in order to enable the physician to identify different types of catheters, and therefore may also be engraved on the sign of the catheter tube 109, or printed on the model identification like for doctors to identify better catheter.

[0065] 考虑到不同的人心脏的大小会有所差异,另外,人的心脏结构虽然大致上是一样的,但是会有细微的不同,因此,为了保证测量的精确性,电极103—般有多个,其中一部分电极103可以用于测量右心室的电流信号,而另一部分电极103则用于测量希氏束的电流信号。 [0065] Taking into account the different size of the human heart will be different. In addition, although the structure of the human heart is roughly the same, but there will be slight differences, therefore, in order to ensure measurement accuracy, as there are electrode 103- plurality, wherein a portion of the electrode 103 may be used to measure a current signal of the right ventricle, and the other portion of the electrode 103 for measuring a current signal of the bundle. 因此,电极103包括:用于检测希氏束电流信号的希氏束电极1031与用于检测右心室电极的右心室电极1032 ;所述希氏束电极1031与所述右心室电极1032均至少有两个;相邻的所述希氏束电极1031之间的距离相等;相邻的所述右心室电极1032之间的距离相等(当右心室电极有多个的时候)。 Thus, electrode 103 comprises: means for detecting a current signal bundle bundle electrode 1031 and the right ventricular electrode for detecting a right ventricular electrode 1032; the bundle electrode 1031 and the right ventricular electrode 1032 each have at least two; the distance between the adjacent electrode 1031 is equal to the bundle; adjacent distance between said right ventricular electrode 1032 is equal to (the right ventricular electrode when a plurality of time).

[0066] 在具体实现的时候,电极103在具体设置的时候,可以在导管的端部设置一端电极,然后在导管的管体设置多个环电极。 [0066] In the concrete implementation, particular when the electrode 103 is provided to be disposed at the end of the electrode end of the catheter, and a plurality of ring electrodes disposed in the tubular body of the catheter. 端电极可以抵触在心脏的内壁上,在起到测量作用的同时,还起到稳定导管的作用,使得在测量的时候,导管不会由于心脏中血液的冲击移动位置而导致测量结果不准确。 Terminal electrodes on the inner wall of the heart can be inconsistent, and measure the effect at the same time functions, also play the role of stabilizing the catheter, so that the time of measurement, because the catheter does not impact the heart caused by blood movement position of the measurement is not accurate. 而环电极则贴在待测部位上,起到测量的作用。 And the ring electrode is attached to the portion to be measured, the measurement functions. 位于最远端的电极103 (即端电极)本身是要贴在右心室的心室壁上,为了保证测量的准确性,另外设置了环电极,与端电极合称右心室电极,用于测量右心室的电学信号。 Located at the distal end of the electrode 103 (i.e. terminal electrodes) itself is affixed to the ventricular wall of the right ventricle, in order to ensure accuracy of measurement, additional ring electrodes are provided, and said terminal electrode together the right ventricular electrode, for measuring the right ventricular electrical signal. 而由于人的心脏构造本身有细小的差异,这个差异就可能表现在希氏束与右心室之间的距离是有误差的,因此希氏束电极1031也是有多个,例如将希氏束电极1031设置为3个、4个、5个或者6个,导管在安置在人身体中的时候,多个希氏束电极1031中可能只有一部分能够与希氏束贴在一起,这样,保证了本申请所提供的心脏电学信息标测电极能够有更加广泛的应用范围。 Since the configuration of the human heart itself has small differences, the difference is between the performance possible with the bundle from the right ventricle is erroneous, and therefore the electrode bundle 1031 is a plurality of, for example, the electrode bundle 1031 set to 3, 4, 5 or 6, when the catheter is disposed in the human body, and bundle a plurality of electrodes 1031 may be able to fit with a portion of the bundle together so that, to ensure the application of the present cardiac electrical information mapping electrodes can be provided with a wider range of applications. 同时,能够起到测量作用的希氏束电极1031数量越多,也越能够提高测量的准确性,减小测量的误差。 The more the number of electrodes 1031 while the bundle, can play a role in the measurement, it is possible to improve the measurement accuracy, the measurement error is reduced.

[0067] 另外,为了使得心脏电学信息标测电极能够有更加广泛的应用范围,还可以将电极103与导管可拆卸的连接,或者能够调整电极103在导管101上的具体位置。 [0067] Further, in order to make the electric power information cardiac mapping electrode is capable of a wider range of applications, electrode 103 can be detachably connected to the catheter, or can be adjusted in the specific position of the electrode 103 on the catheter 101.

[0068] 在具体实现的时候,可以在导管的不同位置设有用于安装电极103的安装槽;该安装槽在不是用的时候,用一结构和电极类似的卡件填充,保证导管的表面是光滑的,在使用的时候,将卡件去掉,将电极103安装在上边。 [0068] In the concrete implementation, the catheter can be provided at different positions of the mounting groove for mounting the electrode 103; the mounting groove when not used, and the electrode filled with a structure similar to the card member, to ensure the surface of the catheter is smooth, when in use, the card member is removed, the electrode 103 is mounted on the upper side. 同时,电极103也是与导线105可拆卸连接的,在导线105上和电极103上设有相互配合的插槽和插针,在将电极103安装到安装槽内的时候,插针插入插槽中,保证导线105和电极103是相互导通的。 Meanwhile, the electrode 103 is removably connected to the wire 105, wire 105 is provided on the upper electrode 103 and the cooperating slots and pins, the electrode 103 is mounted to the installation slot, the pin inserted into the slot to ensure that wire 105 and the electrode 103 are mutually conductive.

[0070] 所述右心室电极的宽度为0.95-1.05mm,和/或,所述右心室电极的宽度为1.8-2.2mm ; [0070] The right ventricular electrode width of 0.95-1.05mm, and / or the right ventricular electrode width is 1.8 to 2.2 mm;
