ACTUATION ASSEMBLIES FOR SURGICAL INSTRUMENTS SUCH AS FOR USE IN ROBOTIC SURGICAL SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18561625 titled 'ACTUATION ASSEMBLIES FOR SURGICAL INSTRUMENTS SUCH AS FOR USE IN ROBOTIC SURGICAL SYSTEMS

The actuation assembly of a surgical instrument consists of an actuation mechanism and an output mechanism. The actuation mechanism includes a piston assembly capable of positive and negative actuation. The output mechanism comprises a fluid vessel connected to a fluid line, a piston sealed and slidably placed within the fluid vessel, and a driver linked to the piston. When the piston assembly is positively actuated, pressurized fluid enters the fluid vessel to move the piston and translate the driver in one direction. Conversely, when negative actuation occurs, the pressurized fluid exits the fluid vessel into the fluid line, allowing the piston to move the driver in the opposite direction.

  • The actuation assembly features a piston assembly designed for both positive and negative actuation.
  • The output mechanism includes a fluid vessel, a piston, and a driver connected to the piston.
  • Positive actuation results in pressurized fluid moving the piston to translate the driver in one direction.
  • Negative actuation causes the pressurized fluid to exit the fluid vessel, enabling the piston to move the driver in the opposite direction.
  • This innovation allows for precise control and movement in surgical instruments.

Frequently Updated Research: - Stay updated on advancements in surgical instrument technology and robotics to see how this actuation assembly may be further improved and integrated into new systems.


Original Abstract Submitted

An actuation assembly of a surgical instrument includes an actuation mechanism and an output mechanism. The actuation mechanism includes a piston assembly configured for positive and negative actuation. The output mechanism includes a fluid vessel in fluid communication with a fluid line connected to the piston assembly, a piston sealingly and slidably disposed within the fluid vessel, and a driver coupled to the piston. In response to positive actuation of the piston assembly, the pressurized fluid flows into the fluid vessel to move the piston to translate the driver in one direction. In response to negative actuation, the pressurized fluid exits the fluid vessel into the fluid line to allow the piston to translate the driver in an opposite direction.
