Abstract: A surgical tool and method of use during laparascopic surgery, the tool including a shaft having a distal region with an elastic modulus E. Distal and proximal regions of the shaft have outer diameters D1 and D2 respectively, with D2>D1. The distal region has a bend and terminates in a working feature having a distal end. The distal region has a length L1 measured in a direction parallel to the shaft axis in the proximal region, and has an offset doff relative to the proximal region where doff>D2. The elastic modulus E and the length of L1 are selected so that the working feature is insertable through an access device yet the distal region does not deflect noticeably when a force of 10 N is applied perpendicular to the distal end of the working feature.

Abstract translation: 在腹腔镜手术中使用的外科手术工具和使用方法,该工具包括具有弹性模量E的远侧区域的轴。轴的远侧和近端区域分别具有D2> D1的外径D1和D2。 远端区域具有弯曲并终止于具有远端的工作特征。 远端区域具有在近端区域中平行于轴线的方向测量的长度L1,并且相对于doff> D2的近端区域具有偏移量doff。 选择弹性模量E和L1的长度,使得工作特征可通过进入装置插入,而当垂直于工作特征的远端施加10N的力时,远侧区域不会显着偏转。
