具体实施方式 Detailed ways

[0017] 本发明掲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附件。 [0017] The present invention is one kind of auxiliary equipment is illustrated kei stapler, in particular for guiding the guide into the stapler body attachment. 现有技术的圆管型装订仪包括钉砧组件、钉仓组件、固定于所述钉仓组件近端的圆管;所述钉仓组件包括相互固定的钉筒和钉仓。 Prior art stapler comprising an anvil assembly, a cartridge assembly is fixed to the proximal end of the tube staple cartridge assembly; said cartridge assembly comprises a cylinder fixed to each other staples and staple cartridge.

[0018] 如图1至图3所示的优选实施例中,所述引导附件包括:用于套设于所述圆管型装订仪的远端的钉筒4的套设部2,设于所述套设部2远端的引导部1,以及设于所述套设部2近端的牵引部3,所述牵引部为两端均固定于所述套设部的牵引绳。 [0018] The illustrated preferred embodiment shown in FIG. 1 to FIG. 3 embodiment, the guide attachment comprising: a sleeve portion sleeved on the distal end of the stapler of the staple cartridge 4 2, provided the guide portion of the distal end portion 2 of the sleeve 1 is provided, and a sleeve disposed in the proximal end 2 provided tractive unit 3, both ends of the traction portion is a traction rope secured to the sleeve portion is provided.

[0019] 所述套设部4为圆筒形,其内径大于所述钉筒的外径,这样整个引导附件可以很容易地套设在钉筒的外側。 [0019] The sleeve portion 4 is cylindrical, having an inner diameter larger than the outer diameter of the staple cartridge, so that the entire boot attachment can be easily provided in the outer sleeve of the staple cartridge.

[0020] 所述引导部I在初始状态为内部中空的具有良好的变形能力的圆台形,所述圆台形的远端的小端表面开设有一个开ロ13,所述开ロ13和引导部、套设部的内部中空贯通。 [0020] The guide portion I in the initial state of the hollow interior with good deformability truncated cone, the small end of the truncated cone surface defines a distal end opening 13 ro, ro the opening portion 13 and the guide , disposed inside the hollow portion through the sleeve. 所述引导部I包括交错连接的锥面部11和内凹部12,所述锥面部11为圆台的外表面,所述内凹部12向圆台的中心凹设。 The guide portion includes a tapered portion I cross connection 11 and the concave portion 12, the tapered portion 11 of the outer surface of the truncated cone, the recessed portion 12 toward the center of the circular recessed station. 所述内凹部可以起到加强整个引导部I的强度的作用。 The concave portion may serve to reinforce the strength of the guide portion of the I whole. 所述引导部I的远端的小端端ロ周长大于等于套设部2的周向剖面的周长,以保证在受到拉力退出圆管型装订仪头部时,圆台形引导部变形为圆筒形,顺利脱离圆管型装订仪的头部。 The distal end of the guide portion of the small end to end I ro circumferential perimeter greater than equal to the circumference of sleeve portion 2 disposed to the cross-section, while under tension to ensure that exit stapler head, frustum-shaped guide portion is deformed cylindrical, smooth departing from the stapler head.

[0021] 所述引导部和套设部的材质为软质材料,例如硅胶。 Material [0021] The guide portion and the sleeve portion of a soft material, such as silica gel. 这样所述引导部具有一定的弾性,可以保护粘膜组织,且具有较好的变形能力与加工切割特性,所述的圆台形在不受任何外力情况下可保持形状稳定,只有在受到外力作用,才变形为需要的形状。 Such a guide portion having a certain property of Dan, can protect the mucosal tissue, and has good characteristics of deformability cutting and processing, the shape of the truncated cone and without any external forces can be maintained dimensionally stable, only by external force, it into the shape desired. 在操作时,先将引导附件套在圆管型装订仪的头部的外面,通过其圆台形的结构引导圆管型装订仪可顺利进入病患体内的手术位置。 In operation, the first guide attachment sleeve in the head of the stapler outside stapler guided smoothly into the surgical site may be the patient's body through which a truncated cone-shaped configuration. 然后通过拉扯牵引绳,使所述引导部I在钉筒的作用下发生弹性变化,即所述锥面部的远端向外发散,并将所述内凹部12也一起向外拉扯并与所述锥面部11形成一个完整的圆周面,使引导附件达到如图4和图5所示的第二状态。 Then traction rope by pulling the resilient portion of the guide under the action change I staple cartridge, i.e., the tapered distal end portion diverging outwardly and the concave portion 12 is also pulled outward together with the tapered portion 11 to form a complete circumferential surface of the guide attachments has reached the second state shown in FIG. 4 and FIG. 这个时候开ロ13的周长已经大于所述钉筒的外周长。 The perimeter 13 ro open time has become larger than the outer perimeter of the staple cartridge. 继续拉扯牵引绳,使所述引导附件向圆管型装订仪的后端移动。 Continue pulling the pulling rope, the movement of the guide attachment to the rear of the stapler. 这样,圆管型装订仪即可进行手木。 Thus, the stapler can be hand wood. [0022] 本发明尚有多种具体的实施方式,例如本发明的引导部I为由锥面部11和内凹部12共同组成的褶皱部,当然除了这种结构,引导部I也可以仅仅是弹性的空心圆台就行,保证引导部既具有引导的功能又能向圆管型装订仪的后端移动。 [0022] The present invention still more specific embodiment, the guide portion of the present invention, for example by I tapered portion 11 and the fold portion 12 composed of a concave portion, of course, in addition to this structure, the guide portion may only elastically I the hollow circular truncated cone on the line, to ensure that both the guide portion having a guide function and can move to the rear of the stapler. 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。 Equivalent substitutions or equivalent formed by converting all the technical solutions, all fall within the scope of the present invention is of the claims.
