The specific embodiment
The present invention has disclosed a kind of puncturing lever that is applicable to surgical operation with the tubular type binding instrument, cooperates with pin anvil shaft, is applicable to an esophagus high position, the operation of rectum low level.
The pin anvil shaft of prior art as shown in Figure 1, for having the straight-bar of a nail anvil axis hole 3, described nail anvil axis hole 3 connects along its axis and is located on the pin anvil shaft 2, one end of described pin anvil shaft 2 is vertically fixed on the nail anvil 1, the other end is provided with boss 4, and this boss 4 is arranged in the nail anvil axis hole 3, and to inner process.The front end of the pin anvil shaft 2 among Fig. 1 is 4 bifurcateds, and each branch is stuck and all inwardly is provided with boss 4.
Puncturing lever of the present invention cooperates with pin anvil shaft among Fig. 1, and first embodiment as shown in Figure 2 comprises being positioned at auxiliary section afterbody, that connect with the pin anvil shaft of tubular type binding instrument; Be positioned at clamping part 7 middle part, that be used for the operating forceps clamping; Be positioned at forward, as to be used to puncture tissue puncture portion 8; Described auxiliary section, clamping part 7, puncture portion 8 are and are wholely set, and are positioned on same the axis, and puncturing lever promptly of the present invention is a straight-bar, and being provided with like this is for piercing tissue better.
