MANUAL KNIFE BAILOUT MONITORING USING INDUCTIVE COUPLING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18540574 titled 'MANUAL KNIFE BAILOUT MONITORING USING INDUCTIVE COUPLING

Simplified Explanation

The robotic surgical tool described in the patent application includes a tool driver with inductive coils, a drive housing with inductive coils, a shaft extending to an end effector, and a firing rod with a magnetically responsive material that moves between retracted and extended positions.

• Tool driver with inductive coils
• Drive housing with inductive coils
• Shaft extending to end effector
• Firing rod with magnetically responsive material
• Movement of firing rod detected by field distortion

Potential Applications

The technology described in the patent application could be used in various surgical procedures where precise control and monitoring of tool movement is crucial, such as minimally invasive surgeries.

Problems Solved

This technology solves the problem of accurately tracking the movement of a firing rod within a surgical tool, providing real-time feedback to the surgeon and improving overall surgical outcomes.

The benefits of this technology include increased precision, improved safety, and enhanced control during surgical procedures, ultimately leading to better patient outcomes.

Potential Commercial Applications

The technology could be commercialized for use in robotic surgery systems, medical device manufacturing, and other industries where precise control of tool movement is essential.

Possible Prior Art

One possible prior art for this technology could be the use of magnetic sensors in surgical tools to track movement and provide feedback to the user.

How does the technology handle potential interference from external magnetic fields?

The patent application does not specifically address how the technology mitigates potential interference from external magnetic fields. This could be a concern in real-world surgical settings where various equipment may generate magnetic fields.

What is the expected lifespan of the components in the robotic surgical tool?

The patent application does not provide information on the expected lifespan of the components in the robotic surgical tool. Understanding the durability and longevity of the technology is crucial for its practical application in surgical settings.

Original Abstract Submitted

A robotic surgical tool includes a tool driver including a first inductive coil, a drive housing releasably mounted to the tool driver and including a second inductive coil, a shaft extending from the drive housing and terminating at an end effector operatively coupled to a distal end of the shaft, and a firing rod extending from the drive housing within the shaft and terminating at the end effector, the firing rod including a magnetically responsive material and being movable within the drive housing between a retracted position and an extended position. One of the inductive coils generates a magnetic field, and the other measures an intensity of the magnetic field and a field distortion caused by movement of the firing rod. A change in the field distortion provides an indication of movement of the firing rod between the retracted and extended positions.
