Nasal Coagulation Suction Device with Anti-Clogging Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coagulation suction devices face challenges in maintaining suction flow due to clogging at the suction openings, especially when the treating portion is in complete contact with tissue, leading to delays and complications during nasal and sinus surgeries.
Innovation Solution
A coagulation suction device with a hollow suction tube, bipolar wires, and an insulation cover, featuring adjustable and malleable distal tips, and suction openings positioned proximal to the distal tip to prevent clogging, along with a suction control mechanism to manage suction force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction opening is positioned at the distal tip for direct tissue contact, then coagulation effectiveness is improved, but suction flow is blocked due to tissue adhesion and clogging
Solution Approach 1:
The device separates the coagulation function (distal tip with bipolar wires) from the suction function (proximal openings), allowing each to operate optimally without interfering with the other. The suction openings are positioned upstream from the distal tip to avoid tissue contact blocking.
Solution Approach 2:
Suction is applied through proximal openings before tissue can fully contact and block the distal tip, preventing clogging in advance. The suction force is established upstream to clear debris before it reaches the treatment zone.
2Productivity
If the suction force is increased to prevent clogging, then suction flow is maintained, but tissue damage and patient discomfort increase
Solution Approach 1:
The suction force is localized to specific proximal openings positioned away from the tissue treatment zone, allowing effective debris removal without applying excessive force to the delicate nasal and sinus tissues. Different regions of the device have different functional qualities.
3Ease of manufacture
If the device structure is simplified, then ease of manufacture is improved, but adaptability to different surgical scenarios is reduced
Solution Approach 1:
The device combines multiple functions (coagulation, suction, navigation) into a single integrated instrument that can adapt to various surgical scenarios within the nasal and sinus cavities. The adjustable distal tip and proximal suction openings provide universal applicability across different procedure types.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device maintains consistent suction flow and reduces tissue adhesion, enhancing surgical precision and safety by preventing clogging and allowing for better navigation in delicate nasal and sinus cavities.
Implementation Method 1
Coagulation tools (also referred to as electrocauterization tools) utilize electrical energy to treat patient tissue such as bleeding sinus tissue. Coagulation procedures may be used to seal blood vessels during surgery to prevent blood flow. Ablation is utilized to vaporize or remove tissue using electrical energy.
Implementation Method 2
Some coagulation tools incorporate a suction feature to clear the surgical site of debris and other visual obstructions. The suction feature may be configured to permit a vacuum to be drawn through the tool from the distal end to a proximal point outside of the patient.

AI summary
A coagulation suction device having an insulation cover and first and second bipolar wires. The insulation cover has a distal end and a distal opening formed at the distal end, and a hollow cavity configured to receive a hollow suction tube. The first and second bipolar wires are encapsulated within the insulation cover and extend along the insulation cover to the distal end. The first and second bipolar wires extend distally beyond a distal-most surface of the insulation cover, and each have an exposed distal end. The exposed distal ends are bent toward each other and terminate adjacent to and spaced apart from each other.
