It is arranged in housing 20, knob 26 and helical tooth wheel set 27 are realized the rotation of distal end of catheter and control the function such as curved.
Preferred construction to realizing the motion of support bar 25 is described in detail below.
Fig. 4 shows a kind of structural representation of the mechanism 23 of driving up in the present embodiment.As shown in figure 4,
The mechanism of driving up for gear auxiliary structure 23, specifically include first gear 231, second gear 232 and
3rd gear 233, the first gear 231 are coaxial with second gear 232, the second gear 232 and
Three gears 233 are engaged, and specifically, can be such as the top half and second of the 3rd gear 233 in Fig. 4
Gear 232 is engaged.The first gear 231, second gear 232 and the 3rd gear 233 pass through axle respectively
234 are fixed in housing 20, and the fixing meanss are known to those skilled in the art, thus the present invention to this not
It is described in detail.
Please continue to refer to Fig. 4, the first gear 231 is identical with the number of teeth of the 3rd gear 233, and diameter
Also identical, the number of teeth of the second gear 232 is more than the number of teeth of first gear 231, the second gear 232
The diameter with diameter greater than first gear 231.Specifically, the number of teeth of the second gear 232 can be with
, into multiple proportion, such as N times (N is the natural number more than 1), in the present invention for the number of teeth of one gear 231
Preferred embodiment in, the twice of the number of teeth of the second gear 232 for the number of teeth of first gear 231.That
, when first gear 231 is rotated, second gear can drive the 3rd gear 233 and be rotated with faster speed,
And the second tooth bar 22 is engaged with the 3rd gear 233, therefore, the movement of the second tooth bar 22 when being synchronized with the movement
Displacement of the distance more than the first tooth bar 21.
The design of the first gear 231, second gear 232 and the 3rd gear 233 is not limited to above-mentioned feelings
Condition, such as number of teeth of first gear 231 only be able to need to be met same with different from the number of teeth of the 3rd gear 233
Displacement (the movement of push button 24 of the displacement of the second tooth bar 22 more than the first tooth bar 21 during step motion
Distance).
The mechanism 23 of driving up is also not necessarily limited to be gear auxiliary structure, for example, it is also possible to be turbine, friction
The combination of wheel and/or gear, it is also possible to realize the different displacements of the first driving member 21 and the second driving member 22,
The present invention is without limitation.
Incorporated by reference to Fig. 5, it is seen then that in the present embodiment, first driving member be the first tooth bar 21, second
Driving member is the second tooth bar 22.First tooth bar 21 is parallel with second tooth bar 22, the push button
24 first ends A for being connected to first tooth bar 21, the second end B of first tooth bar 21 and the first tooth
Wheel 231 is engaged, and first end C of second tooth bar 22 connects the support bar 25, second tooth bar
22 the second end D is engaged with the 3rd gear 233.Specifically, the push button 24 is solid with the connector 30
Fixed, the connector can for example be tubular, or an elongate configuration, the fixture 30 with it is described
First end A of the first tooth bar 21 is fixed, and so as to promote during push button 24, the first tooth bar 21 is also by synchronizing moving.
Rach slot 29 is provided with the housing 20, and first tooth bar 21 and the second tooth bar 22 are located at the tooth bar
In groove 29, positioning is realized.
The support bar 25 is fixed on first end C of second tooth bar 22 by a fixture 251.It is described
Fixture 251 can for example be that first end C of bolt, 25 one end of support bar and the second tooth bar 22 is suffered from
Breach, so as to be fixed using bolt.Preferably, the support bar 25 can pass through the push button 24 so that
The structure of electrophysiologicalcatheter catheter handle is more reasonable.Preferably, a diameter of 0.3～0.8mm of the support bar 25,
For example, 0.4mm, 0.5mm etc., the material of the support bar 25 can be rustless steel or certain for possessing
Metal of shape memory, such as Nitinol etc..
Additionally, except rack structure, in the present invention, the first driving member 21 and the second driving member 22 may be used also
To be scroll bar, scroll bar is engaged with the turbine in mechanism 23 that drives up, and by suitable turbine, gear or is rubbed
Wipe the transmission of wheel, it is also possible to realize that linear motion is converted to rotary motion, then convert rotational motion into straight line
Motion, the present invention are without limitation.
It follows that when push button is promoted, through the first driving member, drive up mechanism and the second driving member
Transmission, support bar can be moved simultaneously, as described above, using mechanism of driving up, enable to
The displacement of two driving members is more notable, i.e., so that the displacement of support bar more than push button promoted away from
From, then the support bar in conduit just can effectively cause distal catheter portion (referring to Fig. 1) real
The actions such as straight, stretching, contraction are pushed away now so that operation is more convenient.
Based on the above, the present invention provides a kind of following electrophysiologicalcatheter catheter, refers to Fig. 1, including electro physiology
Modular catheter 2, the electrophysiologicalcatheter catheter handle 2 are electrophysiologicalcatheter catheter handle mentioned above, raw with the electricity
The electrophysiologicalcatheter catheter main body 1 that reason modular catheter 2 is connected, the electrophysiologicalcatheter catheter main body 1 include that one is given birth to electricity
What the proximal catheter end portion 11 and that reason modular catheter 2 is connected was connected with the proximal catheter end portion 11
Distal catheter portion 12.
Understand via described above, the electrophysiologicalcatheter catheter of the present invention, due to arranging in electrophysiologicalcatheter catheter handle
Second driving member under the drive of the mechanism of driving up, be synchronized with the movement with first driving member,
And the displacement of the second driving member described in when being synchronized with the movement is more than the displacement of first driving member.
Therefore, it is possible to be effectively improved the mobile effect of support bar so that when carrying out less mobile to push button, with regard to energy
The larger movement of support bar is realized enough so that the manipulation more convenient and efficient to electrophysiologicalcatheter catheter distal portions.
Those skilled in the art can carry out the essence of various changes and modification without deviating from the present invention to the present invention
God and scope.So, if these modifications of the present invention and modification belong to the claims in the present invention and its equivalent
Within the scope of technology, then the present invention is also intended to comprising these changes and modification.
