[0050] 在0形环槽46中安装着作为环状弹性部件的0形环42、在其轴向的两侧安装着垫圈41及43。 [0050] In the 0-ring groove 46 as the 0-ring mounted in the elastic ring member 42, washer 41 and 43 mounted on both sides thereof in the axial direction. 通过将把手本体24的阳螺纹部51拧入前端罩44的阴螺纹部52,调节0形环槽46的轴向长度,0形环42沿轴向变形,0形环42相对中轴部分28的锥面40的紧固力改变。 By the male screw portion of the female screw portion 24 of the handle body 51 is screwed into the distal end 52 of the cover 44, the adjustment of the axial length of the O-ring groove 46, O-ring 42 is axially deformed O-ring 42 relative to the central axis portion 28 tapered surface 40 of the fastening force change.

[0051] 0形环42,例如由硅橡胶、丁腈橡胶、氟橡胶等橡胶或合成树脂等构成。 [0051] O-ring 42, for example made of silicon rubber, Ding Jing rubber, fluorine rubber, such as rubber or synthetic resin. 垫圈41、43例如由氟树脂、金属等构成是优选的。 For example, a washer 41, 43 is preferably made of fluorine resin, metal or the like.

[0052] 图3是表示图2的主要部分的剖视图。 [0052] FIG. 3 is a sectional view of a main portion of FIG. 2 FIG. 如该图3所示,在靠近前端罩44的近位端的圆筒部分44b的内周上,利用螺纹结合方式固定棘轮用环50。 As shown in FIG. 3, on the inner circumference near the front end in the proximal end cap 44 of the cylindrical portion 44b of the fixing ring with the ratchet wheel 50 by threaded coupling manner. 即,如图3所示,棘轮用环50是具有与圆筒部分44b的内径大致相同外径的环状的部件,在其外周部分形成能与设在圆筒部分44b的内周的阴螺纹结合的阳螺纹。 That is, as shown in FIG. 3, a ratchet ring 50 is an annular member having an inner diameter of the cylindrical portion 44b is substantially the same as the outer diameter, can be formed in the inner periphery of the cylindrical portion 44b provided in the outer peripheral portion of the female thread binding male thread. 另外,棘轮用环50也可以用螺纹结合方式以外的手段在前端罩44的内周面上实现一体化。 Further, means other than the ratchet can also be used in combination with a threaded ring 50 integrated manner in the inner circumferential surface of the distal end cover 44. 例如,棘轮用环50可以粘接在前端罩44的内周面上,或者通过注射成形一体成形。 For example, a ratchet ring 50 may be bonded to the inner circumferential surface of the distal end cover 44, or integrally formed by injection molding.

[0053] 如图4所示,在棘轮用环50的内周面上形成与转动螺距角度0对应的周方向凹凸52。 [0053] As shown in Fig 4, formed in the inner peripheral surface of the ratchet ring 50 in the circumferential direction of the rotational angle of pitch unevenness corresponding to 52 0. 周方向凹凸52的转动螺距角度0是相邻的凹凸52的凸部和凸部之间或者凹部和凹部之间的围绕轴芯的角度,优选为5〜10度。 Circumferential direction of the unevenness 52 is rotated around the pitch angle 0 is the angle between the axis of the core portion or a concave portion between the convex and concave portions and the convex portions 52 adjacent irregularities is preferably 5 to 10 degrees.

[0054] 另外,在位于该环50的内周侧的把手本体24的外周面上,与周方向凹凸52啮合的棘轮用凸部54沿周方向按转动螺距角度0的复数倍的间隔形成。 [0054] Further, on the outer circumferential surface of the grip body located on an inner peripheral side of the ring 50, 24, the circumferential direction of the convex 52 engages the ratchet wheel by a 54 in the circumferential direction of the convex portion rotatably pitch angle of a plurality of 0-fold intervals. 在图4所示的实施方式中,沿把手本体24的外周面在周方向按90度的间隔在把手本体24的外周面一体成形四个棘轮用凸部54。 In the embodiment shown in FIG. 4, along the outer circumferential surface of the grip body 24 in the circumferential direction at intervals of 90 degrees on the outer circumferential surface of the grip body 24 is integrally formed with four protrusions 54 of the ratchet. 棘轮用环50和棘轮用凸部54相当于棘轮感赋予机构。 Imparting a sense equivalent to the ratchet mechanism with a ratchet ring 50 and the convex portion 54 of the ratchet.

[0055] 接着,对本实施方式所涉及的前端可偏向操作导管2的使用方法进行说明。 [0055] Next, the front end of the present embodiment may be deviated to the operational use of catheter 2 will be described. 操作者用单手抓住把手本体24,用该单手的手指操作操作用按钮22,如图2所示,将操作用按钮22从前端罩44的远位端向拉离方向操作。 Operator grasps the handle body 24 with one hand, with the fingers of one hand with operating the operation button 22, as shown in FIG 2 with the operation direction of the operation button 22 away from the distal end of the distal end cover 44 to pull. 在该情况下,因为中轴部分28连接固定在导管管件4的近位端,所以导管管件4相对操作用丝线30沿轴向相对移动。 In this case, since the axis portion 28 is connected and fixed at the proximal end of the catheter tube 4, the catheter tube member 4 with respect to the operation wire 30 relative axial movement. 其结果,如图I所示,导管管件4的远位端部从直线状态如箭头A所示变成弯曲状态。 As a result, as shown in FIG. I, the distal end of the catheter tube 4 from the linear state as shown by an arrow A into the bent state.

[0056] 而且在本实施方式中,通过中轴部分28相对把手本体24向远位端方向移动,0形环42相对该中轴部分28从锥面40的外径小的一侧向大的一侧沿轴向相对移动。 [0056] Also in this embodiment, the axis portion 28 by moving the grip body 24 relative to the distal end direction, an O-ring portion 42 relative to the central axis 28 from an outer diameter side of the tapered surface 40 of the smaller to the larger side relative axial movement. 即,在这种情况下,与该移动相应,使0形环42向圆周方向扩大的方向的力增加。 That is, in this case, the respective moving the force of O-ring 42 to expand in the circumferential direction is increased. 另外,由于环形槽46的内径不变,所以与该移动对应,中轴部分28和0形环槽46的间隔变窄,0形环42推压中轴部分28及前端罩44的力加强,0形环42和中轴部分28的摩擦力增加。 Further, since the inner diameter of the annular groove 46 unchanged, corresponding to the movement, the central axis 28 and the spacer portion O-ring groove 46 is narrowed, 0-ring 28 and the force of the distal end portion 42 of the pressing cover 44 to strengthen the central axis, O-ring 42 and the central axis of the friction portion 28 is increased.

[0057] 另外,在使中轴部分28相对把手本体24向最近位端方向移动时,0形环42相对中轴部分28相对地位于锥面40的外径最小的位置。 [0057] Further, when the central axis of the handle portion 28 relative to body 24 moves to the nearest end position direction, the O-ring 42 relative to the axis portion 28 is located opposite the position of the minimum outer diameter of the tapered surface 40. 因此,在这种情况下,因为中轴部分28和0形环槽46的间隔最宽,所以0形环42推压中轴部分28及前端罩44的力最小,0形环42和中轴部分28的摩擦力降低。 Thus, in this case, since the spacer portion and the central axis 0-ring groove 46 of the broadest 28, the 0-ring 28 and the force of the distal end portion 44 of the cover 42 presses the smallest axis, an O-ring 42 and the central axis friction portion 28 is decreased. 因此,在使操作用按钮22相对把手本体24向离开轴向的方向移动的移动初期,操作用按钮22由很轻的力沿轴向移动。 Therefore, when the operation buttons 22 relative to the initial movement of the handle body 24 moves in a direction away from the axial direction, the operation button 22 with a small force from the axial direction.

[0058] 另外,即使让手指离开操作用按钮22,由于0形环42与外径大的锥面40接触,因此由于其摩擦力,操作用按钮22不在轴向移动。 [0058] Further, even if your finger off the operation buttons 22, since the 0-ring 42 in contact with the outer diameter of the tapered surface 40, and therefore due to friction, with the operation button 22 does not move axially. 因此,即使让手指离开操作用按钮22,如图I所示的导管管件4的远位端部也可以保持弯曲的状态。 Therefore, even if your finger off the operation button 22, the distal end of the catheter tube shown in Figure I-4 can be maintained in a bent state.

[0059] 为了使图I所示的导管管件4的远位端部为笔直的状态,逆着锥面40和0形环42的摩擦力,只要使操作用按钮22轴向移动就可以。 [0059] FIG. I order to make the distal end of the catheter tube 4 shown in a straight state, the tapered surface 40 against the frictional force and O-ring 42, so long as axial movement of the operation button 22 can be used. 此时,0形环42从锥面40的大的外径部分向小的外径部分移动,所以锥面40和0形环42的摩擦力逐渐变小。 At this time, O-ring 42 from the large outer diameter portion of the tapered surface 40 is moved to the small outer diameter portion, the tapered surface 40 and the O-ring 42 of friction gradually decreases.

[0060] 在本实施方式所涉及的导管用把手20中,将前端罩44螺纹结合在把手本体24的外周上,通过调节其螺纹拧入深度,可以调整0形环42对中轴部分28的外周锥面40的紧固力。 [0060] In the catheter handle according to the present embodiment 20, 44 threaded distal end cover bonded to an outer periphery of the grip body 24, by adjusting the screwing depth can adjust the O-ring 42 and the centering section 28 an outer circumferential tapered surface 40 of the fastening force. 而且,此时,通过作为棘轮感赋予机构的棘轮用凸部54和周方向凹凸52的啮合,根据前端罩44相对把手本体24的围绕轴芯的转动螺距角度0赋予棘轮感(咯嗒声和感觉)。 Further, at this time, the concavo-convex 52 engages with the circumferential direction of the convex portion 54 and the ratchet mechanism of imparting a sense as the ratchet wheel, in accordance with the rotation angle around the pitch axis of the distal end cover 44 of the core relative to the handle body 24 of the ratchet wheel to impart a sense of 0 (snapping sound and feel). 因此,作业者可以对每一转动螺距角度微调整前端罩44的螺纹拧入深度。 Thus, the operator can rotate the angle of pitch for the fine adjustment of each end cover 44 is screwed into the threaded depth. 即,作业者可以根据棘轮感的数目微调整0形环42的紧固力。 That is, the operator can finely adjust the fastening force of O-ring 42 according to the number of ratchet sense.

[0061] 因此,可以适当保证0形环42的紧固力,在任意轴向位置能够使操作用按钮22容易地止动。 [0061] Thus, it is possible to ensure a suitable fastening force of the O-ring 42, in any axial position of the manipulation button 22 can be made easily stop. 另外,可以再调整相对把手本体24的前端罩44的螺纹拧入深度,能够按规定数的转动螺距角度9停止前端罩44的螺纹拧入,能够微调整0形环42的紧固力,即微调整操作用按钮22的操作力。 In addition, readjustment of the handle body relative to the distal end 44 of the cover 24 is screwed into the screw depth can be rotated by a predetermined number of pitch-angle end cover 9 screwed stop 44 can be finely adjusted fastening force of the O-ring 42, i.e., fine adjustment operation force of the operation button 22. 另外,一旦0形环42的紧固力设定以后,由于通过棘轮用凸部54和周方向凹凸52的啮合,限制相对把手本体24的前端罩44的转动,所以对0形环42的锥面40的紧固力的时效改变少。 Further, once the O-ring 42 of the set fastening force, since the irregularities 52 engages with the circumferential direction of the convex portion 54 and the ratchet to restrict rotation of the handle body relative to the distal end 44 of the cover 24, so the O-ring 42 of the cone aging surface 40 of the fastening force change little.

[0062] 另外,本发明不限于上述的实施方式,可以进行各种改变。 [0062] Further, the present invention is not limited to the above embodiments, but may be variously changed. 例如,在上述的实施方式中,如图4所示,在把手本体24的外周沿周方向等间隔形成四个棘轮用凸部54,但也可以如图5所示,沿周方向等间隔或不等间隔形成三个或者其它数量的棘轮用凸部54。 For example, in the above-described embodiment, shown in Figure 4, the spacer is formed by four ratchet protrusion 54 in the circumferential direction of the outer periphery of the grip body 24, but may be 5, at equal intervals in the circumferential direction, or unequal intervals three or other number of convex portion 54 of the ratchet. 但是沿周方向在把手本体24的外周面上等间隔形成三个或更多的棘轮用凸部54是优选的。 However, in the circumferential direction like the outer circumferential surface of the grip body 24 is formed of three or more spaced ratchet convex portion 54 is preferred. 形成三个或更多的棘轮用凸部54时,可以减轻相对把手本体24的中轴部分28 (操作部)的晃动(向与轴向垂直的方向的晃动)。 It is formed by three or more ratchet convex portion 54 can be reduced (the operation portion) of the fluctuation (in a direction perpendicular to the axial wobbling) relative to the central axis of the handle portion 24 of the body 28.

[0063] 或如图6所示,在把手本体24的外周面上,与图4所示的转动螺距角度0对应地形成周方向凹凸52a,在棘轮用环50的内周面上,也可以沿周方向按转动螺距角度的复数倍的间隔形成与周方向凹凸52a啮合的棘轮用凸部54a。 [0063] or, as shown, the outer peripheral surface of the handle body 24, and the rotation angle of the pitch shown in FIG. 6 weeks 0 formed corresponding to the concavo-convex direction 52a, the inner peripheral surface of the ring 50, the ratchet may be circumferential direction is formed by protruding ratchet portions 54a and 52a engage the circumferential direction by the rotation of the uneven pitch angle of a plurality of spaced times. 棘轮用环50和棘轮用凸部54相当于棘轮感赋予机构。 Imparting a sense equivalent to the ratchet mechanism with a ratchet ring 50 and the convex portion 54 of the ratchet. [0064] 进而,本发明所涉及的导管用把手,不限于图示的实施方式的前端可偏向操作导管,也可以适用于其他的导管。 [0064] Further, the catheter according to the present invention with the handle, the distal end is not limited to the illustrated embodiments of the catheter may be biased operation, it may be applicable to other catheters.
