背景技术 Background

[0002]目前,手术切割缝合器械在外科手术中得到广泛地应用。 [0002] Currently, the surgical stapler in surgical instrument has been widely applied. 已知的手术缝合器械主要包括手柄、细长体和执行装置,其中执行装置用于夹持组织、切割所夹持的组织,并对切口两侧的组成实施缝合。 Known surgical stapling instrument including a handle, an elongated body and the execution means, wherein the execution means for gripping tissue, cutting the clamped tissue, and the composition of the incision sutured embodiment both sides. 执行装置包括用于夹持组织而能够张开/闭合的夹钳,夹钳的一个夹钳臂设有钉砧,夹钳的另一个夹钳臂设有钉仓,钉仓中设有缝钉和推钉器。 Executing means comprising means for clamping tissue can open / close the clamp, a clamp arm with a clamp anvil, the other clamp arm clamp is provided with the cartridge, the cartridge is provided with a staple and push nail. 夹钳闭合而夹持组织时,推钉器被驱动而将缝钉朝向钉砧推出,缝钉穿过组织并在钉砧的配合下成型,从而完成击发缝合。 When the clamp is closed and clamped tissue, pushing nails and staples are driven toward the anvil launch staples through the tissue and in the anvil with the molding, thus completing the firing of stapling.

[0003] 击发缝合时,夹钳的两臂之间的距离(即,夹钳的闭合高度)决定了缝钉的成型高度,对于缝钉的成型非常重要,该距离的大小以及该距离沿夹钳臂长度方向上的一致性都会影响缝钉成型的质量(特别是缝钉的成型高度),从而影响组织缝合的质量。 [0003] When the firing of stapling, the distance (ie, the clamp shut height) between the two arms of the clamp determines the staple forming height for the staples molding is very important, the size of the distance and the distance along the folder Consistency will clamp arm length direction of the impact on the quality (especially staple forming height) forming staples, thus affecting the quality of tissue suturing.

[0004] 具体地,一方面,当夹钳所夹持的组织较厚时,夹钳臂的闭合高度通常过大,并且夹钳臂通常会发生变形,导致夹钳的闭合高度不一致,通常远端张开的距离较大,而近端距离较小。 [0004] Specifically, on the one hand, when the jaws are clamped tissue is thick, the height of the clamp arm closure typically too large, and deformation of the clamp arm usually occurs, resulting in highly inconsistent clamp closure, usually much end open distance greater proximal distance is small.

[0005] 另一方面,当所夹持的组织较薄时,夹钳臂的闭合高度如果过小,较容易将组织压缩的厚度过小,导致破坏组织的细胞结构以及缝钉的成型高度过低,而使得组织不容易愈 [0005] On the other hand, when the clamped tissue thin, shut height of the clamp arm is too small, relatively easy to organize a compressed thickness is too small, resulting in destruction of the cell structure and organization of the staple forming height is too low , and makes the organization is not easy to heal
