Enhanced Articulation Joint with Adaptive Helical Lumen

An improved surgical instrument with a helical lumen that enables enhanced articulation and control of the end effector, addressing limitations in the original design.

The original patent's articulation joint with helical lumen has limitations in terms of flexibility, precision, and control. The new inventive concept addresses these limitations by introducing an adaptive helical lumen with varying pitch, enabling smoother and more precise articulation of the end effector.

The enhanced surgical instrument features a shaft assembly with a helical lumen that includes a spiral portion with a varying pitch. This adaptive design allows for improved articulation of the end effector, enabling surgeons to engage tissue at precise angles and with increased control. The instrument may also include a controller that adjusts the rotation of the shaft assembly based on feedback from a sensor, ensuring optimal articulation. Additionally, the end effector may feature a curved portion that follows the helical path of the lumen during articulation.

The new claims introduce the concept of an adaptive helical lumen with varying pitch, which is not present in the original patent. This innovation enables improved articulation and control of the end effector, making the new inventive concept novel and non-obvious.

Alternative embodiments of the inventive concept may include different shaft assembly designs, varying pitch patterns, or additional sensors and actuators to enhance articulation control. The concept may also be adapted for use in other medical instruments or robotic systems.

The enhanced surgical instrument has significant commercial potential in the medical device industry, particularly in the areas of laparoscopic and endoscopic surgery. The improved articulation and control capabilities may lead to increased adoption and market share in these growing markets.
