Methods for pluggable end-effectors of robotic surgical instruments
First Claim
Patent Images
1. A method of surgery comprising:
- plugging base portions of a first end effector and a second end effector respectively into a first receptacle of a mechanical wrist and a second receptacle of the mechanical wrist coupled to a shaft of a robotic surgical instrument of a robotic surgical system, the mechanical wrist having a first joint for a first degree of freedom and a second joint for a second degree of freedom;
coupling a first spring latch, attached to the base portion of the first end effector, to the first receptacle of the mechanical wrist;
coupling a second spring latch, attached to the base portion of the second end effector, to the second receptacle of the mechanical wrist; and
rotating, by cables and pulleys, the first receptacle of the mechanical wrist and the second receptacle of the mechanical wrist together about a pin such that the first and second receptacles of the mechanical wrist maintain a relative position to each other to yaw the first and second end effectors together in a same direction.

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.

12. A method of surgery comprising:
-
depressing a first spring latch and a second spring latch, attached to respective first and second end effectors, to decouple the first spring latch and the second spring latch from a first receptacle of a mechanical wrist and a second receptacle of the mechanical wrist respectively; unplugging base portions of the first and second end effectors respectively from the first receptacle of the mechanical wrist and the second receptacle of the mechanical wrist of a robotic surgical instrument of a robotic surgical system; plugging the base portions of the first and second end effectors respectively into the first receptacle of the mechanical wrist and the second receptacle of the mechanical wrist coupled to a shaft of the robotic surgical instrument of the robotic surgical system, the mechanical wrist having a first joint for a first degree of freedom and a second joint for a second degree of freedom; and rotating, by cables and pulleys, the first receptacle of the mechanical wrist and the second receptacle of the mechanical wrist together about a pin, such that the first and second receptacles of the mechanical wrist maintain a relative position to each other, to yaw the first and second end effectors together in a same direction. - View Dependent Claims (13, 14, 15, 16)
