Wristed robotic surgical tool for pluggable end-effectors
First Claim
1. An electrosurgical end effector cartridge to detachably couple to a robotic surgical instrument of a robotic surgical system, the electrosurgical end effector cartridge comprising:
- a first moveable end effector having a jaw portion and a base portion;
a first latch coupled to the first moveable end effector near the base portion, the first latch is flexible to detachably couple the first moveable end effector to a first receptacle of the robotic surgical instrument;
a second moveable end effector having a jaw portion and a base portion; and
a second latch coupled to the second moveable end effector near the base portion, the second latch is flexible to detachably couple the second moveable end effector to a second receptacle of the robotic surgical instrument.

Abstract
In one embodiment of the invention, a replaceable electrosurgical end effector cartridge is provided to couple to a mechanical wrist of a surgical instrument for a robotic surgical system. The replaceable electrosurgical end effector cartridge includes two pluggable end effectors and a pair of spring latches. The two end effectors are moveable end effectors having a jaw portion, an off-center portion, and a base portion in one embodiment. The replaceable electrosurgical end effector cartridge may further include a fastener to rotatably couple the end effectors together.
