Bipolar Probe Inclined Plane for Tissue Coagulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bipolar treatment devices face challenges in efficiently coagulating living tissue over a wide range without excessive carbonization, and in maintaining effective contact between the probe and jaw electrodes during high-frequency treatments.
Innovation Solution
The device incorporates a probe with an inclined plane on its distal surface and a jaw with a corresponding inclined plane, allowing for surface contact with living tissue at angles between 30 to 80 degrees, enabling efficient high-frequency current flow through a physiological saline solution for coagulation, while the probe's suction path is designed to maintain stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a columnar probe with curved distal portion is used to form inclined planes for tissue contact, then the coagulation efficiency and wide-area treatment capability are improved, but the risk of excessive carbonization and tissue adhesion increases
Solution Approach 1:
A physiological saline solution is introduced as an intermediary medium between the inclined plane electrode and the living tissue. The saline solution conducts the high-frequency current while preventing direct contact between the electrode and tissue, thereby enabling efficient coagulation over a wide area while preventing excessive carbonization and adhesion. The saline solution acts as a mediator that transfers energy without the harmful side effects of direct electrode-tissue contact.
2Productivity
If the probe and jaw are brought into direct contact with living tissue for high-frequency current passage, then the coagulation effectiveness is improved, but the tissue adhesion to probe or jaw occurs
Solution Approach 1:
The physiological saline solution serves as an intermediary that enables current passage through tissue without requiring direct electrode-tissue contact. The saline solution maintains electrical conductivity for effective coagulation while preventing thermal adhesion between the electrode surfaces and tissue, thereby resolving the contradiction between effectiveness and adhesion prevention.
3Ease of operation
If the inclined plane angle is optimized for surface contact (30-80 degrees), then the contact stability and ease of operation are improved, but the device complexity increases due to precise geometric requirements
Solution Approach 1:
The inclined plane is designed with specific angular parameters (30-80 degrees relative to the longitudinal axis) to optimize contact stability with tissue surfaces. By carefully controlling the geometric parameters of the inclined plane, the device achieves stable surface contact that facilitates ease of operation while maintaining manufacturability through defined angular ranges rather than overly restrictive specifications.

AI summary
An energy treatment device includes a probe in which a suction path is defined inside along a longitudinal axis to a distal surface portion. The probe includes a first protrusion protruding an outer peripheral distal end of an outer peripheral portion toward a first perpendicular direction perpendicular to the longitudinal axis and perpendicular to open/close directions of the jaw. The distal surface portion includes an inclined plane in which it goes toward a distal direction side as it goes from the first perpendicular direction toward a second perpendicular direction that is opposite to the first perpendicular direction, the inclined plane extending from a first end position, located to the first perpendicular direction side of a first root position of a first protrusion, to a second end position, located to the second perpendicular direction side of the suction path.
