MULTI-CABLE MEDICAL INSTRUMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18591811 titled 'MULTI-CABLE MEDICAL INSTRUMENT

Simplified Explanation:

The patent application describes a medical instrument with cable pairs wound around input spindles to control the movement of an instrument shaft structure. The cables are connected so that rotating the input spindles actuates specific degrees of freedom. Pulleys in the instrument redirect the cables towards the instrument shaft.

  • The medical instrument includes cable pairs wound around input spindles.
  • Rotating the input spindles actuates degrees of freedom of an instrument shaft structure.
  • First pulleys redirect first cables towards the instrument shaft, while second pulleys redirect second cables.
  • The pulleys are mounted at different levels, with second pulleys redirecting cables through the first level.
  • Cables may cross at different levels.

Potential Applications: This technology could be used in various medical instruments requiring precise control over degrees of freedom, such as robotic surgical tools or endoscopes.

Problems Solved: This technology addresses the need for accurate and efficient control of instrument shaft movements in medical procedures.

Benefits: - Enhanced precision in controlling instrument movements - Improved maneuverability in tight spaces during medical procedures - Increased efficiency and accuracy in surgical tasks

Commercial Applications: Potential commercial applications include the development of advanced robotic surgical systems, minimally invasive surgical tools, and other medical devices requiring precise movement control.

Questions about the Technology: 1. How does this technology improve the accuracy of medical procedures? 2. What are the potential cost implications of implementing this technology in medical devices?

Frequently Updated Research: Stay updated on advancements in medical instrument technology, particularly in the field of robotic surgery and minimally invasive procedures.


Original Abstract Submitted

A medical instrument includes cable pairs respectively wound around input spindles and connected to actuate degrees of freedom of an instrument shaft structure. The cables may connect so that rotating the input spindles actuates corresponding degrees of freedom. First pulleys in the instrument may receive first cables from the input spindles and redirect the first cables toward the instrument shaft, and second pulleys may receive second cables from the input spindles and redirect the second cables toward the instrument shaft. In one configuration, the first and second pulleys are respectively mounted at first and second levels, and the second pulleys redirect the second cables through the first level. Additionally or alternatively, one level of cables may cross while the other level of cables does not.
