  • Surgical instrument with offset jaw actuator
    Patent number: 5989277
    Abstract: A tool for grasping or cutting with an offset jaw actuator is shown. The offset provides a consistent width to the actuator discouraging buckling under heavy loading situations. The offset also provides for greater contact area between the actuator and inner tip. The interface of the actuator with the inner tip is machined into the inner tip from the side resulting in an instrument that is easier and cheaper to manufacture and clean while retaining maximum strength for cutting or grasping.

  • Actuating forces transmission link and assembly for use in surgical instruments
    Patent number: 5727428
    Abstract: A link, and assembly and instrument using same, for transmitting actuating forces from an actuating member to a work member. The link includes a link body having a distal end and a proximal end. The distal end of the link body is movably interconnected with the work member by a distal interconnection element such as an arcuate groove-and-flange assembly, and is interconnected at its proximal end to an actuating member by a proximal pivotal interconnection element. The proximal element transmits a first actuating force from the actuating member to the work member. A shoulder, disposed on the link body preferably between the distal and proximal elements for interconnecting, engages the actuating member when a second, greater actuating force is applied to the actuating member in a direction opposite to that of the first actuating force. The greater force is thereby transmitted fully to the work member. The link assembly preferably includes a spacer member to assist positioning of the actuating member.
