Then, use the adhesive tape 64 with described structure the remainder 61a of this wire 61 to be fixed on the inner face of handle main body 30 (the second operation).Now, as previously mentioned, in the region relative with cutting plate 31 (on the inner face of the second grip part 30b), so that this remainder 61a becomes and ties up the state of bunchy and the mode of temporary fixed state is fixed remainder 61a.
After this, in handle main body 30, cutting plate 31 (the 3rd operation) is installed.Thus, the electrode catheter shown in Fig. 1～Fig. 31 has just completed.
In addition, between described the first operation and the second operation, also can further comprise that this adapter 62 is the parts that are independent of handle main body 30 toward the operation of mounted connector 62 in handle main body 30.Or, for example, when adapter 62 is parts of handle main body 30, also can be originally just arranged on and under the state in handle main body 30, carries out described the first operation at this adapter 62.While using a kind of front method, adapter 62 can carried out to weld job etc. from the inner state taking out of handle main body 30, thereby can easily carry out weld job etc.Because by after all wires 61 and adapter 62 welding etc., directly adapter 62 is arranged in handle main body 30, so can reduce the difficulty of each operation.That is to say, a kind of situation of method before using, with use after a kind of situation of method compare, the degree of freedom of the operation in the time of can improving being electrically connected between wire 61 and adapter 62.
[effect]
(basic operation)
When checking and treat arrhythmia, the catheter tube 2 in this electrode catheter 1 is inserted in patient's body by blood vessel.Now, the operation according to operator to operating portion 4, near the shape of front end that is inserted in the catheter tube 2 in body for example changes on a direction or both direction.Specifically, if operator holds handle 3 with one, and with the finger of this hands, operating portion 4 is moved up (with reference to the arrow d1 in Fig. 1) at the axle of handle 3, grasp position 51 in catheter tube 2 for example, along axially relatively move (, being pulled to base end side).Its result, crooked along the direction as shown in the arrow d2 as in Fig. 1 near the front end of catheter tube 2.That is, operator passes through along axial operation operating portion 4, and the deflection of waving that can carry out catheter tube 2 operates.In addition, by handle main body 30 is swayed, can be inserted under the state in patient body in catheter tube 2 near the bending direction front end of free setting catheter tube 2.
At this, when inspection such as for arrhythmia etc., use the electrode (front termination electrode 22 and annular electrode 21) that is inserted in the catheter tube 2 in patient body to measure heart potential.Then, according to the information of this heart potential, carry out having or not and inspection that degree is relevant of arrhythmia with check point etc.
On the other hand, when treatment such as for arrhythmia etc., be installed on patient body surface to pole plate (not shown) and be inserted between the electrode of the catheter tube 2 in patient body and carry out high frequency (RF:Radio Frequency) energising.By such high frequency, switch on, the position for the treatment of target (blood vessel etc.) are burnt (ァ Block レ mono-シ ョ Application) selectively, carry out thus the transdermal therapeutic of arrhythmia etc.
(effect of handle 3)
In addition, (Fig. 2) as mentioned above, in this electrode catheter 1, the base end side of wire 61 that is electrically connected to and is introduced into the inside of catheter tube 2 with the electrode of catheter tube 2 extends in handle 3 and is electrically connected to (being fixed on adapter 62) with adapter 62.In addition, as shown in Figure 2, the handle 3 of electrode catheter 1 forms by being arranged on the handle main body 30 of base end side of catheter tube 2 and the cutting plate 31 detachable with respect to handle main body 30, is to have the so-called handle of cutting apart structure.
For thering is the described handle of cutting apart structure, as previously mentioned, thus for example can cutting plate 31 is rear to be welded they is electrically connected to adapter 62 cardinal extremity of wire 61 pulling down.Therefore,, for the ease of such weld job, need to make the length of wire 61 have some surpluses.For this reason, for example, as shown in Figures 2 and 3, in handle main body 30, be provided with the remainder 61a of wire 61.
, after such weld job, the remainder 61a of this wire 61 can become obstruction when assembling (in handle main body 30, cutting plate 31 being installed).Specifically, in comparative example as shown in Figure 4, as the handle 103 of electrode catheter 101, when (covering) cutting plate 31 being installed in handle main body 30, if this remainder 61a is projected into outside in handle main body 30, will produce following problem, that is: because remainder 61a is easily clamped by handle main body 30 and cutting plate 31, on this remainder 61a, have the kink of generation and broken string equivalent risk, its result can cause the reliability of product (electrode catheter 101) to reduce.
So in the electrode catheter 1 of present embodiment, as shown in Figures 2 and 3, the remainder 61a of described wire 61 is fixed in handle main body 30 by adhesive tape 64 (fixed part).Thus, as mentioned above, for example, for example, when being electrically connected to operation (weld job) afterwards when cutting plate 31 being installed in handle main body 30 between the cardinal extremity at wire 61 and adapter 62, different from described comparative example 1, its result is as follows, that is: the remainder 61a that can reduce or avoid (preferably avoiding) wire 61 from handle main body 30 interior to outside outstanding and nipped risk.
In addition, because use the such low price of adhesive tape 64 again simple parts just can realize the fixed part of bringing into play described effect, so can the increase of production cost is restrained minimum in, minimum can be restrained in the space that arranges of the fixed part of handle 3 inside.In addition, even described low price simple parts again also can be realized following fixing etc. in temporary fixed state effectively by simple operation.
In addition,, in this electrode catheter 1, the remainder 61a of wire 61 is fixed with temporary fixed state by adhesive tape 64.Thus, such as in the reliability test after manufacturing electrode catheter 1 etc., when wire 61 is judged as insufficient (loose contact) with being electrically connected to of adapter 62, can improve operability.That is to say, because be fixing in temporary fixed state, for example, so can easily pull down the remainder 61a of wire 61 from handle main body 30, therefore can easily carry out the maintenance activity (, re-starting the operation of welding) of electrical connections.
In addition, the remainder 61a of this wire 61 is fixed in handle main body 30 in the region relative with cutting plate 31 (the formation region of the second grip part 30b).Thus, when pulling down cutting plate 31, easily from outside, see this remainder 61a.Therefore, relevantly with remainder 61a really take that industry and reconditioning work etc. easily carry out as, thereby can improve operability.
In addition, the remainder 61a of this wire 61 is fixed in handle main body 30 to be tied the state of bunchy.Therefore, this remainder 61a is just not easy from handle main body 30 interior outstanding to outside more, when cutting plate 31 is installed, just is more not easy to be jammed, and result can further improve reliability.
Furtherly, when adhesive tape 64 consists of insulating properties material, even for example in the situation that wire 61 has many (being provided with a plurality of electrodes in catheter tube 2 as in the present embodiment), also can avoid wire 61 to be short-circuited each other by adhesive tape 64.Its result can further improve reliability.
As described above, in the present embodiment, by adhesive tape 64, the remainder 61a of wire 61 has been fixed in handle main body 30, when cutting plate 31 being installed in handle main body 30, thus the remainder 61a that can reduce or avoid this wire 61 from handle main body 30 interior to outside outstanding nipped risk.Therefore, kink and the broken string equivalent risk of the remainder 61a of wire 61 can be reduced, thereby the reliability of electrode catheter 1 can be improved.
In addition, because handle 3 is the formations that may be partitioned into handle main body 30 and cutting plate 31, so carrying out the component configuration operation of handle 3 inside, maintenance activity and they while really taking industry etc. as, there is no need handle 3 all to decompose.That is to say, as long as cutting plate 31 is pulled down from handle main body 30, just can easily in handle 3 inside, carry out described operation, thereby can improve operability.
Particularly because the handle main body 30 of present embodiment is by the first grip part 30a of cardinal principle tubular and in the rear end side of this first grip part 30a, the second grip part 30b along the cardinal principle water guide tubulose being axially integrally formed forms, and cutting plate 31 is detachable with respect to this second grip part 30b, so can access following effect, that is: the handle 3 of present embodiment, compare with the structure (handle 3A) of the second embodiment described later, can improve the rigidity of handle main body 30.Therefore, even operator grasps handle main body 30, handle main body 30 can not deform etc. yet, can make operator feel at ease to use.Consequently can further improve the operability of electrode catheter 1.
