Methods, systems, and devices relating to surgical end effectors

摘要

The embodiments disclosed herein relate to various medical device components, including components that can be incorporated into robotic and/or in vivo medical devices, and more specifically including end effectors that can be incorporated into such devices. Certain end effector embodiments include various vessel cautery devices that have rotational movement as well as cautery and cutting functions while maintaining a relatively compact structure. Other end effector embodiments include various dual end effector devices that have more than one end effector.

主权项

1. An in-vivo vessel sealing end effector, the end effector comprising:
(a) an in vivo device body operably coupled to an arm of an in vivo robotic device, wherein the arm and the device body are configured to be positioned entirely within a cavity of a patient, the device body comprising:
(i) a cautery component actuation motor;(ii) a cutting component actuation motor;(iii) a jaw actuation motor;(iv) a cautery component shaft disposed within the body and operably coupled to the jaw actuation motor; and(v) an electrical connection rotatably fixed to the cautery component shaft;(vi) a first slip ring coupled to the device body, wherein the first slip ring is configured to maintain electrical contact with electrical connection during rotation of the cautery component shaft; (b) a bipolar vessel cautery component operably coupled to the device body, the cautery component comprising:
(i) a stationary jaw coupled to a distal end of the cautery component shaft;(ii) a mobile jaw pivotally coupled to the distal end of the cautery component shaft; and(iii) a cutting component operably coupled to the cutting component actuation motor,wherein the cautery component is operably coupled to the cautery component actuation motor, andwherein the electrical connection is electrically coupled to one of the mobile jaw and the stationary jaw, and (c) an external electrical source electrically coupled to the first slip ring.
