Rotating Tissue Resection Sealing for Continuous Cauterization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical resection devices, such as clamps and staplers, require significant operative time due to a cumbersome step-wise process, leading to inefficiencies and increased healthcare costs, and existing energy devices do not effectively seal and cauterize tissue in a continuous manner.
Innovation Solution
A surgical resection device with a first and second part that are rotatable and translatable relative to each other, applying continuous electrical energy to cauterize tissue while translating across the organ surface, reducing the need for multiple clamping and sealing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional clamp-like resection devices are used, then tissue can be sealed and cauterized, but operative time increases significantly (10 to 45 minutes)
Solution Approach 1:
The device enables continuous tissue sealing and cauterization through a linear motion mechanism that moves along the tissue length, eliminating the need for repeated clamping and releasing operations. The continuous application of electrical energy during linear movement provides uninterrupted hemostasis and tissue preparation throughout the resection site.
Solution Approach 2:
The patent replaces traditional mechanical clamping actions with an electrical energy-based cauterization system combined with linear motion. Instead of relying on repeated mechanical compression and release cycles, the device uses continuous electrical current delivery during linear movement to achieve tissue sealing and cauterization.
2Reliability
If multiple clamping and sealing steps are performed, then tissue can be processed, but procedure complexity increases
Solution Approach 1:
The device merges multiple separate surgical functions into a single integrated operation: tissue compression, electrical energy delivery for cauterization, and linear advancement along the tissue length all occur simultaneously in one continuous motion, eliminating the need for separate clamping, sealing, and resection steps.
Solution Approach 2:
The device performs multiple functions simultaneously - it compresses tissue, delivers electrical energy for cauterization, and advances along the tissue length - making it a multi-functional tool that replaces several separate instruments and procedural steps.
3Productivity
If conventional staplers and clamps are used, then resection can be performed, but healthcare costs increase due to time and resource consumption
Solution Approach 1:
The continuous linear motion with uninterrupted electrical energy delivery eliminates repeated stopping and starting, reducing total operative time and increasing surgical productivity while maintaining complete tissue processing.

AI summary
A surgical method includes providing a resection device having a first part and a second part that is spaced apart from the first part to define an opening therebetween. A material is positioned within the opening. The second part is translated relative to the first part to compress the material. Energy is continuously applied to the first part and the second part. The second part is rotated relative to the first part while applying energy to the first part and the second part to cauterize the material, thereby translating linearly along the material's surface cauterizing the material in a continuous fashion. In some embodiments, devices and systems are disclosed.
