after using certain cycle, can absorb stationary blade 33 by dissolving the absorption, the stationary blade dissolves the back completely, the cycle that the stationary blade dissolves completely and the recovery cycle phase-match of intestinal operation, lose the effect of connecting two elastic bands 32, first subassembly 3 and the second of strutting strut resets after the pulling force that subassembly 4 lost elastic band 32, lose the effect that supports the intestinal wall, the aspiration cylinder 51 resets simultaneously, store up pressure case 52 internal pressure and recover, circular arc recess 55 can not adsorb the intestinal wall, thereby the cut-off equipment wholly loses support and fixed effect, it can to take out it.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications are possible which remain within the scope of the appended claims.
