電気手術装置
Document Type and Number:
Japanese Patent JP6943368
Kind Code:
B2
Abstract:
A surgical instrument having an end effector mounted on the end of an elongate shaft extending from a handle. The end-effector is capable of different operations, including grasping, cutting, and sealing and/or coagulating tissue, and one of the operations is controlled by a trigger mechanism contained within the handle. In some embodiments, the end effector includes a pair of curved jaw members and blade assembly having a cutting blade at its distal end. The trigger mechanism drives blade assembly longitudinally within the elongate shaft such that the cutting blade protrudes between the jaw members. To help the trigger mechanism push blade assembly around the curved jaws, the distal end of blade has a graduated flexibility that easily bends to the shape of the jaw members. The distal end of the blade may be provided with a low friction coating so that it can easily slide between the jaw members.
