手术切割缝合器械及其闭合高度控制装置 Surgical cutting and stapling instrument shut height control means

技术领域 FIELD

[0001] 本发明涉及手术器械领域,尤其涉及手术切割缝合器械装置。 [0001] The present invention relates to surgical instruments, and more particularly relates to a surgical stapling instrument cutting means.

背景技术 Background technique

[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 instrument in a surgical stapler 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 both embodiments of the suture incision. 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 includes means for clamping tissue capable of opening / closing of the clamp, the clamp arm is provided with a clamp anvil, the other clamp gripper arm is provided with a staple cartridge, the staple cartridge with staples and push staple. 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 clamp tissue, the staple is driven to push the staples toward the anvil Release, staples through the tissue and formed in cooperation with the anvil, thereby 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 firing of stapling, the distance (i.e., the height of the clamp closure) between the two arms forming tongs determines the height of the staples, the staple is very important for molding, the size of the distance and the distance along the clip consistency in the longitudinal direction will affect the quality of the caliper arm shaped staples (especially the staple forming height), thus affecting the quality of the stapled tissue.

[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 clamp is clamped tissue is thicker, the shut height of the clamp arm generally too large, and the clamp arm generally deformed, resulting in inconsistent clamp shut height, typically much the flared end of a large distance, while the 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 is thin, the height of the clamp arm closure is too small, relatively easily compressed tissue thickness is too small, the cell structure results in destruction of tissue and the staple forming height is too low , so that the organization is not easy to heal
