SURGICAL INSTRUMENT WITH SELECTABLE INTEGRAL OR EXTERNAL POWER SOURCE

摘要

A surgical instrument includes a body, a shaft, and an end effector. The shaft extends distally from the body. The end effector is located at a distal end of the shaft. The end effector includes an active feature configured to operate on tissue. The body includes a drive feature operable to drive the active feature of the end effector. The body is operable to selectively couple with a variety of power sources such that the drive feature may receive electrical power form a battery or from a corded power source, based on a user's preference. The body may include a handpiece that has a socket configured to receive a battery or cable adapter. The body may removably receive various kinds of shaft assemblies to provide various operating modalities. The shaft assemblies may include user interface features.

主权项

1. An apparatus comprising:
(a) an end effector, wherein the end effector includes an active feature configured to operate on tissue, wherein the active feature comprises one of:
(i) an ultrasonic blade, or(ii) at least one electrode operable to apply RF energy to tissue; (b) a shaft, wherein the shaft has a proximal end and a distal end, wherein the end effector is disposed at the distal end of the shaft; and (c) a body, wherein the shaft extends distally from the body, wherein the body comprises:
(i) a power interface feature configured to receive power from at least two different kinds of electrical power sources, wherein the at least two different kinds of electrical power sources comprise a cordless battery and a corded electrical power source, and(ii) a drive feature responsive to electrical power to drive the active feature of the end effector, wherein the drive feature is configured to receive electrical power from the power interface feature such that the drive feature is operable to drive the active feature of the end effector based on electrical power from a power source coupled with the power interface feature.
