Shown in Figure 1, the heart electrical information mapping electrodes that this utility model embodiment provides comprises: conduit 101; One end of described conduit 101 is provided with electrode 103, and described electrode 103 is coaxial with described conduit 101;
The other end of described conduit 101 is provided with union joint 104;
Described electrode 103 has multiple; Multiple described electrode 103 is for obtaining the signal of telecommunication of heart diverse location.
When specific implementation, by heart electrical information mapping electrodes by surgical installation is in human body, because the heart of human body communicates with blood vessel, therefore the electrode 103 set by conduit 101 end will be made along the blood vessel (tremulous pulse or vein) of human body, arrive predetermined installation site, in order to effectively reduce the quantity of mapping electrodes, the position that multiple electrode 103 can arrive generally can both be arrived by a blood vessel.And at human heart, in the structure of vascular circuit, Xinier reservoir and right ventricle can be arrived by a blood vessel, therefore, the heart electrical information mapping electrodes that the application provides is mainly used in the detection to Xinier reservoir and right ventricle electrical signal, and in the heart electrical information mapping electrodes provided in the application, owing to being provided with multiple electrode 103 on conduit, the position of different electrodes 103 is owing to being different, the position that the heart that therefore can contact is different, therefore, it is possible to obtain the signal of telecommunication of heart diverse location, like this, as long as the distance controlled well between electrode 103, just a conduit can be passed through, the electrode of Xinier reservoir and right ventricle detected respectively, like this, decrease the consumption of conduit, the first reduces the cost of operation, and then can inspection fee be reduced, its two be install conduit few, the time that operation uses also reduces accordingly, reduce the time of exposure that people is rolled off the production line at X-ray, thus reduce X-ray line to the impact of human body.
Consider the signal of telecommunication that electrode 103 can be allowed heart diverse location can be detected, and can ensure that electrode 103 can by the electrical signal transfer detected by it to corresponding checkout equipment, such as ecg measurement instrument, therefore in conduit, be provided with the multiple conducting wires 105 of not conducting mutually, each electrode 103 is connected to different wires 105.
When specific implementation, can arrange cavity in conduit, be arranged on by wire in cavity, one end of wire, through the sidewall of conduit, is connected with electrode 103.The other end of wire, in conduit 101, arrives union joint position along cavity.It should be noted that owing to being electrode 103 will be extend into internal blood vessel, therefore in order to prevent the blood of internal blood vessel from entering in the cavity of conduit 101, electrode 103 is seal with the connecting portion of conduit 101.
Except placing except wire 105 by the cavity be arranged in conduit, can also directly use the material making conduit to build outside multiple conducting wires and make catheter body, like this, wire 105 and conduit 101 connect as one, and to be conducive in operation process doctor to the manipulation of whole conduit.
Union joint has two effects:
One is that the electrical signal transfer transmitted by connected wire is to relevant checkout equipment;
Two is in the process of operation, and doctor can this union joint hand-held, by rotating the conduit be connected with union joint, to adjust direction, the path of conduit 101 intravasation, makes electrode 103 finally abut in position concrete to be measured in heart.
Generally, conduit is fixedly connected with union joint, namely when the mapping electrodes of entirety manufactures, conduit and union joint are made into an entirety, union joint can be used for the checkout equipment of join dependency away from one end of conduit, and by wire be delivered to union joint electrical information pass to relevant checkout equipment.For each patient, the mapping electrodes adopted is all disposable.
In addition, except child suffers from except the people of special heart disease with some, the size of other human heart is all similar, but still can there is certain difference, therefore for different people do check time, the mapping electrodes of concrete use will according to after finally carrying out X-ray imaging to human body, doctor specifically judges according to the result of imaging again, therefore in order to increase alternative (the namely different people of heart electrical information mapping electrodes, on the heart electrical information mapping electrodes used, distance between the position of electrode 103 or electrode 103 may be different), also in order to make, union joint is recursive to be used, namely the cost checked further is reduced, different patients, only need to change conduit 101, therefore in the heart electrical information mapping electrodes that the application provides, by conduit 101 and the dismountable connection of union joint 104.
When specific implementation, conduit is provided with a limiting stand 110 away from one end of electrode 103; On described conduit, cover has joint sleeve 111; This joint sleeve 111 can be blocked by this limiting stand 110, makes joint sleeve 111 cannot skid off conduit 101 in the one end away from electrode 103 from conduit 101.In this joint sleeve, be provided with female thread, union joint 104 is provided with the external screw thread cooperatively interacted with this female thread, this joint sleeve can by female thread and external screw thread, is dismountablely connected on union joint 104.
Simultaneously, after the blood vessel of human body to be inserted by conduit by doctor, need steering nozzle to adjust the position of conduit, because conduit 101 itself removably connects with union joint 104, therefore in the process of doctor's steering nozzle, may cause rotating between conduit 101 and union joint 104, rotation between conduit and union joint can have a certain impact to the operation of doctor, in order to eliminate this impact, conduit is also formed with clip for limiting, and this clip for limiting can make to occur between conduit 101 and union joint 104 rotating.
In addition, can also arrange external screw thread, union joint 104 is arranged at the female thread that this external screw thread cooperatively interacts on this joint sleeve, same, this joint sleeve can pass through this female thread and external screw thread, is dismountablely connected on union joint 104.
In addition, consider that wire 105 is arranged in conduit 101, conduit 101 is connected with union joint 104 is dismountable, therefore also needs wire 105 to be connected with union joint 104 is dismountable.Specifically when realization, be provided with the groove 106 that multiple and described conduit 101 communicates in the inside of described union joint 104; Connecting contact pin 107 is provided with in each groove 106; Wire 105 described in every root stretches into a described groove 106, is connected with the described connecting contact pin 107 in groove 106 is dismountable.
General, the direction of groove 106 arranges towards the direction at conduit 101 place, like this, can facilitate the connection of conduit inside conductor 105 and connecting contact pin 107.Meanwhile, the quantity of groove 106 and connecting contact pin 107 generally can more than the quantity of wire 105, and such as just wiring contact pin is set to 14, ordinary circumstance, and the quantity of wire is all within 10.The conduit 101 that not only the application can be provided and union joint, can also be arranged on this union joint 104 by the conduit being used for the mapping electrodes measuring other position electrical information.There are how many regardless of the wire 105 in conduit 101, ensure that each root wire all can be connected on union joint 104.
When being connected with wire 105 by connecting contact pin 107, conveniently both connection, the one end extending into groove 106 at wire 105 is also connected with plug connector 108, and described connecting contact pin 107 can insert in described plug connector 108.
Can also plug connector 108 be arranged in groove 106 in addition, connecting contact pin 107 be set on wire 105 simultaneously, or directly wire 105 be used as connecting contact pin 107, equally also can realize removably connecting between wire 105 and union joint 104.
In addition, due in the process of operation, doctor needs continuous steering nozzle to adjust the trend of conduit, the position of electrode 103, and the blood vessel of human body be not one by all means, but there is various branch road and radian, therefore, conduit must be possess certain flexible flexible conduit, this flexible conduit can under the control of doctor, in human vas, the path along blood vessel bends, like this, supravasal electrode 103, by continuous steering nozzle or the position adjusting conduit, can be delivered to default inspection position by doctor.
And the surface of flexible conduit is smooth, namely catheter surface does not possess any projection, screw thread, agnail, rust staining etc., only in this way, when can ensure that conduit advances in human vas, reduces conduit to the damage of human vas.
