具体实施方式 Detailed ways

[0024] 本发明揭示了一种圆管型装订仪的辅助器械,尤其是一种用于引导圆管型装订仪进入体内的引导件,具体如图所示的实施例。 [0024] The present invention discloses one kind of auxiliary equipment stapler, in particular for guiding a stapler into the body of the guide member, as shown in the specific embodiment according to FIG.

[0025] 现有技术的圆管型装订仪,如图5所示,包括圆管7,设于所述圆管7远端的钉砧组件、钉仓组件,及可移动地设置在所述钉仓组件内并用于与所述钉砧组件连接的钉砧拉杆9 ;所述钉仓组件包括相互固定的钉筒I和钉仓3,及可移动地设置在钉筒I内部的切刀11和推钉片5,所述钉仓3的远端为钉仓面,与钉砧组件的钉砧面相对。 [0025] The prior art stapler, 5, 7 comprises a pipe, the pipe 7 provided in the distal end of the anvil assembly, the cartridge assembly, and movably disposed in the within the staple cartridge assembly and an anvil for the rod 9 is connected to the anvil assembly; said cartridge assembly comprises a cutter fixed to each other staple cartridge and the staple cartridge 3 I, and movably disposed in the interior 11 of cartridge I and staple pushing plate 5, the cartridge 3 to the distal end surface of staple cartridge, the anvil surface opposite the anvil assembly.

[0026] 本发明中,所述引导件为一整体环绕而形成的螺旋形柔性塑胶件,即该引导件是一个柔性塑胶件整体环绕围成的螺旋形物件,类似于弹簧。 The flexible plastic helical member [0026] the present invention, the guide member is integrally formed surrounding, i.e., the guide member is integrally surrounded by a spiral-shaped objects surrounded by a flexible plastic element, like a spring. 所述的引导件即为一段“弹簧线”。 Said guide section is the "spring line."

[0027] 由图1、图2中可以看出,本优选实施例的双螺旋引导件为一整体呈圆锥形的空腔柔性塑胶件,因为用于围设引导件的柔性塑胶件可以采用橡胶或其他塑胶,根据其工艺的程度,可以将引导件的“弹簧线”制成不同的粗细,导致引导件的内腔大小不一。 [0027] In FIG 2 it can be seen from Figure 1, the present preferred embodiment of the double helix embodiment of the guide member integral conical cavity flexible plastic member, as a flexible plastic member is disposed around the guide member may be made of rubber or other plastics, the process according to the extent thereof, the guide member may be "spring wire" made of different thickness, resulting in the lumen of the guide member sizes. 所述双螺旋引导件包括一个近端17和一个远端15,所述远端15到近端17的外径逐渐增大,所述近端17的内壁的直径大于或等于所述钉筒I的最大外径,这样,当所述双螺旋引导件配接于所述圆管型装订仪时,所述引导件可以套在所述钉筒I的外周上。 The double helix guide member 17 includes a proximal end 15 and a distal end, an outer diameter of the distal end 15 to the proximal end 17 gradually increases the diameter of the proximal end of the inner wall 17 is greater than or equal to the staple cartridge I the maximum outer diameter, so that, when the double helix to the mating guide stapler, the guide member may be fitted over the outer periphery of said staple cartridge I.

[0028] 本发明的特点在于:所述引导件的圆锥形壁13包含第一柔性条19和第二柔性条21,两者平行缠绕形成一个螺旋体,所述第一柔性条19和第二柔性条21间隔螺旋设置并紧贝占。 [0028] The features of the present invention is that: the conical wall 13 of the guide member comprises a first flexible strip 19 and the second flexible strip 21, both forming a parallel spiral wound, said first and second flexible strips 19 of the flexible spacer bar 21 is provided and tightly spiral shell accounts. 所述第一柔性条19采用相对硬质材料制得,即强度较好、硬度较高;所述第二柔性条21采用相对软质材料制得,即强度较差、易撕拉。 The first using a relatively flexible strip 19 made of a hard material, i.e. with better strength, high hardness; using the second flexible strip 21 made of relatively soft material, i.e. poor strength, easy tearing. 所述第一柔性条19和第二柔性条21相互之间为粘接或二次注塑而成。 The first 19 and second flexible strips 21 are each formed of a flexible adhesive or overmolding.

[0029] 由于第一柔性条19和第二柔性条21相互紧密地缠绕在一起,所以整个引导件的圆锥形壁13的强度较大,在进行引导圆管型装订仪进入病人体内时不会坍塌。 [0029] Since the first flexible strip 19 and the second flexible strip 21 closely intertwined with each other, the strength of the entire conical wall 13 of the guide member is large, when the stapler guide into the patient is not performed collapse. 另由于第一柔性条19和第二柔性条21相互紧密地缠绕在一起,导致整个引导件的圆锥形壁13的外侧相对平滑,在进行引导圆管型装订仪进入病人体内时该外壁不会刮伤组织,其效果比现有技术的单一螺旋型柔性条要好很多。 In addition, because the first flexible strip 19 and the second flexible strip 21 closely intertwined with each other, resulting in the entire outer conical wall of the guide member 13 is relatively smooth, the outer wall of the guide is not performed when the stapler into the patient scratching tissue, which is much better than the single helical type flexible strip prior art.

[0030] 所述第一柔性条19的远端还设有一个牵引件23。 [0030] The first distal end of the flexible strip 19 is further provided with a pulling member 23. 所述牵引件23为所述第一柔性条19的远端的延伸段,所述牵引件23的自由端伸向圆管型装订仪的近端。 The traction member 23 to the distal end of the extension of the first flexible strip 19, the free end of the traction member 23 toward the proximal end of the stapler. 或者,所述牵引件23也可以是固定在所述第一柔性条19的远端的牵引线。 Alternatively, the traction member 23 may be fixed at the distal end of said first flexible strip 19 of the pull wire. 即只要起到牵引作用即可。 That is, as long as you can play a role in traction. 所述圆管型装订仪钉筒上设有至少I个引导孔,所述牵引件23在初始状态时从所述引导孔中穿过。 The tube type is provided with at least one guide hole I on the stapler cartridge and the traction member 23 through the hole from the guide in the initial state.

[0031] 在操作时,先将本优选实施例的引导件套接在钉仓组件的远端,然后引导圆管型装订仪进入人体内,此时牵引件23的自由端穿过引导孔并露出于病人体外。 [0031] In operation, the first embodiment of the present preferred embodiment the guide socket at the distal end of the staple cartridge assembly, and then guided into the stapler body, at this time the free end of the pulling member 23 through the guide hole, and exposed to the outside of the patient. 接着拉扯所述牵引件23,使所述第一柔性条19按由远及近的顺序呈螺旋解体,最终形成为一条由第一柔性条和第二柔性条组成的长条状体并被一次性地从所述引导孔中被抽出于圆管型装订仪夕卜,类似于将“弹簧线”拉成一直线。 Subsequently pulling the pulling member 23, the first flexible strip 19 by a spiral order from the disintegration of far and near, and ultimately the formation of an elongated body of a first and a second flexible strip and is composed of a flexible strip of the guide hole from being drawn to the stapler Bu Xi, similar to the "spring wire" pull in line. 在此过程中,由于第二柔性条21的强度较差,很容易被拉断,其断体会随着第一柔性条19 一起拉出于圆管型装订仪外。 In this process, due to poor strength of the second flexible strip 21 is easily pulled off, which is broken as the experience with the first flexible strip 19 to pull out of the outer stapler. 当然上述的实施例也可以从装订仪外侧抽出,只要改变牵引件位于引导件上的连接位置即可。 Of course, the above-described embodiments may be extracted from the outside of the stapler, simply changing the connection position to the traction member is positioned on the guide member.

[0032] 图3揭示了本发明的第二实施例。 [0032] Figure 3 discloses a second embodiment of the present invention. 由于优选实施例中,所述近端17的内壁的直径大于或等于所述钉筒I的最大外径,使所述引导件可以套在所述钉筒I的外周上。 Since the preferred embodiment, the diameter of the proximal end of the inner wall 17 is greater than or equal to the maximum outer diameter of cartridge I so that the guide member can be fitted over an outer periphery of said staple cartridge I. 但是当圆锥形壁13的壁厚相对较大时,会明显增加圆管型装订仪的外径,从而影响圆管型装订仪的插入,同时也会增加病人的痛苦。 However, when the wall thickness of conical wall 13 is relatively large, it will significantly increase the outer diameter of the stapler, thereby affecting the stapler is inserted, but also increase the patient's pain. 因此第二实施例中,所述圆锥形壁13的近端17为一卡接部25,该卡接部25的壁厚小于位于所述远端的圆锥形壁13的壁厚。 Thus the second embodiment, the proximal end 13 of the conical wall 17 is a snap portion 25, the thickness of the locking portion 25 is located is less than the wall thickness of conical wall 13 of the distal end. 这样大大减小了圆锥形壁13的壁厚带来的影响。 This greatly reduces the impact of the wall thickness of the conical wall 13 brings. 第二实施例的其他结构和操作方法与第一实施例相同,在此不再赘述。 Other structure and operation method of the second embodiment is the same as the first embodiment, it is not repeated here.

[0033] 图4揭示了本发明的第三实施例,为了进一步减小圆锥形壁13的壁厚带来的影响,所述圆锥形壁13的近端17还向外延伸有一卡接部25,即向圆管型装订仪的近端延伸,所述卡接部25的外径小于或等于钉筒I的内径。 [0033] Figure 4 discloses a third embodiment of the present invention, in order to further reduce the influence of the wall thickness of conical wall 13 is brought, a wall of said conical proximal end portion 13 of the clip 17 extends further outwardly 25 , namely the proximal end of stapler extends, the inner diameter of the staple cartridge card I outer diameter portion 25 is less than or equal to. 这样,所述卡接部25卡在所述钉筒I内侦牝进而使所述引导件配接于圆管型装订仪的远端钉筒上。 Thus, the card engagement portion 25 within the cartridge and thus make the I investigation female mating guide member on the distal end of cartridge of the stapler. 由于圆锥形壁13的最大直径基本等于钉筒的最大直径,因此将引导件装在圆管型装订仪上后并没有增大钉筒I的外径,使圆管型装订仪插入体内更加方便。 Since the maximum diameter of the conical wall 13 is substantially equal to the maximum diameter of cartridge, and thus the guide member is mounted on the stapler does not increase the outer diameter of cartridge I so that stapler inserted into the body more easily .

[0034] 本发明的操作简单,只需一步就可以实现引导件脱离所述圆管型装订仪。 [0034] The simple operation of the present invention, can be achieved in one step from the guide member stapler. 而现有技术需要多步骤操作,而且其弹簧线不能呈长条状脱离,很容易会刮伤组织。 Whereas the prior art requires multiple steps, and its spring from the elongated strip line can not easily be scratched tissue.

[0035] 进一步地,引导件的第一柔性条19和第二柔性条21的近端可以设有区别于引导件整体的颜色区域,特别为色彩鲜艳的黄色,一般采用喷涂方式,用于提示医生引导件全部移出于圆管型装订仪。 [0035] Further, the guide bars 19 and the first flexible member of the proximal end of the second flexible strip 21 may be provided with the entire color region is different from the guide member, in particular colorful yellow, generally by spraying mode for prompting all out to guide doctors stapler. 由于黄色区域的存在,当医生看见该黄色区域的时候证明已经将引导件全部拉出于所述圆管型装订仪外。 Due to the presence of the yellow region, when the doctor to see the yellow region has been demonstrated to pull out all of the guide member outer stapler.

[0036] 本发明尚有多种具体的实施方式,等同替换或者等效变换而形成的所有技术方案,均落在本发明要求保护的范围之内。 [0036] Within the present invention, there are various specific embodiments, equivalents, substitutions or equivalent formed by converting all the technical solutions, all fall within the scope of the invention as claimed.
