Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vessel sealing and cutting systems during surgical interventions face challenges such as high usage costs due to disposable nature, inefficiency in sealing large vessels, risk of bleeding, and damage to adjacent tissues from heat radiation, especially with existing laser-based systems that lack mechanical tightening and are not cost-effective for repetitive use.
Innovation Solution
A vessel sealing and cutting system utilizing a reusable laser processing mechanism with a surgical equipment comprising a lower and upper jaw, a laser module, and a thermo-stable part for controlled laser energy application, allowing simultaneous sealing and cutting with mechanical tightening, reducing heat transfer to adjacent tissues and enabling safe, cost-effective procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If laser energy is used for vessel sealing and cutting, then cutting precision is improved, but heat radiation damages adjacent tissues
Solution Approach 1:
A reflective cavity is introduced as an intermediary between the laser source and the vessel. This cavity reflects and directs laser energy onto the vessel surface while shielding adjacent tissues from direct heat radiation. The cavity acts as a controlled delivery system that confines thermal energy to the target area only.
Solution Approach 2:
The laser energy application is localized to the specific vessel region requiring sealing or cutting. The reflective cavity focuses energy precisely on the target site, creating a localized thermal effect that seals the vessel without affecting surrounding tissues. This selective energy delivery resolves the contradiction between precise cutting and tissue protection.
2Reliability
If disposable surgical equipment is used, then sterility and safety are improved, but usage costs increase
Solution Approach 1:
The surgical system is divided into two segments: a disposable surgical equipment portion (jaws, reflective cavity, protective components) that ensures sterility and safety, and a reusable laser source portion that generates the energy. This segmentation allows the critical patient-contact components to be disposable while the expensive laser generator can be reused across multiple procedures, resolving the cost-sterility contradiction.
3Reliability
If mechanical tightening force is applied to close vessel ends, then sealing effectiveness is improved, but device complexity increases
Solution Approach 1:
The sealing function is merged with the laser energy delivery system. The reflective cavity that delivers laser energy also serves as the structure that applies mechanical tightening force to close the vessel ends. This merging of functions achieves effective sealing through the integrated system without requiring separate complex mechanical sealing components.
