具体实施方式 Detailed ways

[0026] 本发明提供了一种穿刺器,如图I、图7所示,包括一套管I和内置其中用于刺破组织的穿刺杆(图中未示意),所述套管I上开设有一贯穿套管壁的小孔12,所述穿刺器还包括一设置在套管I上的气阀50,所述气阀50包括一枢轴管22和一用于接通气源的管接头21,枢轴管22与管接头21 —体成型,所述枢轴管22与所述管接头21中间均开设有内部通道110,且内部通道110是相互联通的,气源通过管接头21的通气端210进入,所述小孔12与所述内部通道110相通,小孔12与套管I的主通道10联通。 [0026] The present invention provides a trocar as I, shown in FIG. 7, comprising a sleeve in which I and built for puncturing tissue piercing rod (not illustrated in the drawing), on the sleeve I defines an aperture through the casing wall 12, the trocar further includes a valve disposed on the sleeve 50 is I, the valve 50 includes a shaft tube 22 and a gas supply tube for turning joint 21, the pivot tube 22 and the pipe joint 21 - shaping the pivot tube 22 and the nipple 21 are intermediate 110 defines an internal passage and the internal passage 110, interconnected, gas source 21 through the pipe joint the venting port 210 enters the aperture 12 in communication with the internal passage 110, the sleeve aperture 12 of the main passage 10 I Unicom. 所述枢轴管22的侧壁开设有一通气孔220,通气孔220与内部通道110联通,为了使得气源的流通更顺畅,枢轴管22与管接头21设置为相互垂直固定,所述通气孔220与所述小孔12直径相当。 The pivot tube 22 defines the side wall 220 has a vent, vent channel 220 and the inner link 110, in order to make air flow more smoothly, the pivot tube 22 is provided with a nipple 21 fixed vertically to each other, through the hole 220 equivalent to the diameter of the aperture 12. 所述套管I上开设有一用于放置气阀50的拗口5,气阀50通过枢轴管22在拗口5的第一位置和第二位置间作枢轴运动进行通气、闭气切换。 The sleeve defines a mouthful for placing valve 550, the valve 50 via a pivot tube 22 for venting the first and second positions mouthful intercropping 5 pivotal movement of the switching breath I.

[0027] 如图I所示,当气阀50在套管I的第一位置时,所述通气孔210的轴线与所述小孔12的轴线共轴,联通内部通道110和气源;此时,气阀处于开启状态,气源从通气端210进入到内部通道110,通过通气孔220进入到小孔12内并进入到套管I的主通道10内。 [0027], when the sleeve valve 50 in a first position I, the axis of the axis of the vent hole 210 coaxial bore 12, the internal passage 110 and a gas source Unicom FIG. I; this when the valve is in an open state, air enters from the venting port 210 into the internal passageway 110, through vent hole 220 into the aperture 12 into the sleeve and into the main passage 10 I. 此时,气阀50在拗口5内的状态及与套管I的位置可由图2、图3得知。 At this time, the state of valve 50 and within the sleeve 5 mouthful I may be a position that FIG. 2, FIG. 3.

[0028] 如图4所示,当气阀50在套管I的第二位置时,所述管接头21与所述套管壁11的外表面紧贴,由于套管I上开设了拗口5,所以,如图5所示,所述管接头21与所述拗口5外表面紧贴,此时,气阀5处于关闭状态,内部通道110和气源的通路即被切断;气源不能进入到套管I的主通道10内。 [0028] As shown, when the sleeve valve 50 at the second position I, the pipe joint 21 in close contact with the outer surface 11 of the sleeve wall 4, since the upper casing opened mouthful I 5 Therefore, as shown in FIG. 5, the pipe joint 21 and the outer surface 5 against the mouthful, at this time, valve 5 is closed, via gas source 110 will turn off the internal passageway; air can not enter the main channel I to the sleeve 10. 气阀50在拗口5内的状态及与套管I的位置可由图5、图6得知。 Valve 50 in the state hard to pronounce the sleeve 5 and a position that I may be 5, 6.

[0029] 为了使得气阀50能在拗口5内更好的定位,也会方便操作者使用时更能掌握气阀50的旋转度,所述拗口5内设置有用于定位气阀50的定位槽31,枢轴管22的侧壁,在所述通气孔210的正上方或正下方上设有与定位槽31相配合的凸起3,凸起3可采用树脂材料或有弹性的材质,为了凸起3能在定位槽31内旋转运动,所述凸起3的外表面为圆弧状,此时定位槽31的剖截面也为圆弧形,当然也可以采用角状的凸起3,对应定位槽31的剖截面为角状。 [0029] In order that the valve 50 can be better positioned within the mouthful 5, will facilitate the operator more control over the rotation of the valve 50 is in use, the mouthful is provided for positioning the valve 5 is positioned within the groove 50 31, the pivot tube side walls 22, 31 is provided with a positioning groove on the mating projections 3 directly above or below the vent hole 210, the protrusion 3 can be a resin material or an elastic material, for projections 3 can rotate in the positioning grooves 31 motion, the convex outer surface 3 of the arc-shaped, cross-sectional positioning groove 31 at this time also in an arc shape, of course, also be employed angular projections 3, cross-section corresponding to the positioning groove 31 is angular.

[0030] 所述凸起3在所述定位槽31内枢轴运动形成气阀50的第一位置和第二位置,所述定位槽31分两部分,且两部分之间非平滑过渡,用于使气阀50处于第一位置与第二位置都相对稳定,不会轻易从第一位置滑动到第二位置,或从第二位置滑动到第一位置,只有当操作人员亲自将气阀50在第一位置与第二位置之间切换,才可以实现通气、闭气的切换,且会产生明显的手感。 [0030] The projection 3 is formed in the pivotal movement of the positioning slot 31 of the first valve position and a second position 50, the positioning groove 31 in two parts, and a non-smooth transition between the two parts, with to cause valve 50 is in the first position and the second position are relatively stable and will not easily slide from a first position to a second position, or sliding from a first position to a second position, the operator only when the valve 50 personally between a first position and a second position switch, can be achieved only ventilation, the switching of breath, and can create significant feeling. 结合图2和图5得知,第一、第二位置形成的夹角为90度,即所述气阀50在第一位置时,所述定位槽31的顶点对应定位槽31的第一部分,气阀50在第二位置时,所述定位槽31的顶点对应定位槽31的第二部分,两部分圆弧顶点到圆点的半径相互垂直。 In conjunction with FIGS. 2 and 5 that, first, the second angle is 90 degrees formed at a position, i.e. the valve 50 in the first position, the positioning groove 31 of the apex portion 31 corresponding to the first positioning groove, valve 50 in the second position, the second portion of the positioning groove 31 corresponding to the vertex of the positioning groove 31, two arcuate vertex portions perpendicular to the radius of the dot.

[0031] 在操作过程中,根据需要转动气阀50即可控制气源的联通与切断,由于凸起3与定位槽31的结构更好的定位了气阀50,同时,增强了气阀50旋转时的受力,不会由于操作者无意的触碰导致气阀转动而漏气。 [0031] In operation, valve 50 is rotated as needed to control communication with the air supply cut off, since the projection 3 and the structure of the positioning groove 31 of the valve 50 better positioning, while enhancing the air valve 50 force during rotation, since the operator does not inadvertently touch cause rotation of valve leakage.

[0032] 本发明尚有多种实施方式,凡采用等同变换或者等效变换而形成的所有技术方案,均落在本发明的保护范围之内。 [0032] The various embodiments of the present invention, there, where the use of all technical equivalents transform or equivalent conversion scheme formed, are within the scope of the present invention.
