  • Patent number: 5203785
    Abstract: Hook scissors end effectors are provided for a laparoscopic instrument. The hook scissors end effectors generally comprise first and second blades, with at least one of the blades pivotally engaging the laparoscopic instrument. Each blade comprises an elongate straight blade member with an integral transverse hook element at the distal end of the blade member. The hook elements each extend towards the other blade member and each hook element is offset from its blade member so that a narrow recess is provided between opposing first and second hook members upon closing of the first and second blade members. The elongate straight blade members provide a straight scissors cutting action therebetween so that the contiguously adjacent portions of the blade members gradually come together in a continuous bearing contact to effect a cutting action.
