发明名称 Surgical instruments employing sensors
摘要 According to an aspect of the present disclosure, a surgical instrument for operating on tissue is provided. The surgical instrument includes an end effector including a first tissue engaging member and a second tissue engaging member in juxtaposed relation to the first tissue engaging member; a gap determination element operatively associated with each of the first tissue engaging member and the second tissue engaging member for measuring a gap distance between the first tissue engaging member and the second tissue engaging member; and a tissue contact determining element operatively associated with a respective tissue contacting surface of at least one of the first tissue engaging member and the second tissue engaging member. The present disclosure also relates to methods of using the surgical instrument.

主权项 1. A surgical instrument for operating on tissue, comprising: a shaft including at least one frame member and at least one clamp slide member abutting the at least one frame member; an end effector including a first tissue engaging member and a second tissue engaging member, at least one of the first and second tissue engaging members movable from a first configuration for positioning tissue therebetween to a second configuration for compressing tissue; and a gap determination element including a body portion coupled to the at least one frame member and a wiper coupled to the at least one clamp slide member, the wiper displaceable in relation to the body portion and movable with the at least one clamp slide member to move the at least one movable first and second tissue engaging member from the first configuration to the second configuration, wherein movement of the wiper from the first configuration to the second configuration causes change in an electrical property of the gap determination element that is indicative of a distance between the first and second tissue engaging members, wherein the electrical property of the gap determination is at least one of capacitance, inductance, voltage, and resistance.
