Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hemorrhoid treatments, such as medicated ointments and creams, are inadequate in providing comprehensive relief, while surgical options involve significant recovery periods and risks, and existing electrical current treatments require manual intervention to adjust for body resistance fluctuations.
Innovation Solution
A hemorrhoid treatment system with a handheld device and computing device that automatically adjusts the output voltage to compensate for patient body resistance fluctuations, using a variable resistance network and current sensing resistor to deliver a steady level of current to the hemorrhoid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual electrical current treatment is used for hemorrhoids, then current can be delivered to the hemorrhoid, but the treatment requires continuous manual adjustment to compensate for body resistance fluctuations
Solution Approach 1:
The system employs a feedback control mechanism where a controller continuously monitors body resistance through a sensing electrode and automatically adjusts the output voltage via a variable resistance network to maintain a constant current level, eliminating the need for manual adjustments during treatment
Solution Approach 2:
The treatment system performs self-regulation by automatically detecting changes in body resistance and adjusting its own output parameters through the controller and variable resistance network, making the system self-correcting without operator intervention
2Reliability
If surgical treatment is used for hemorrhoids, then complete removal of hemorrhoids is achieved, but long recovery period and surgical risks are involved
Solution Approach 1:
The invention replaces mechanical surgical intervention with an electrical field-based treatment method, using controlled current delivery through a probe electrode to achieve therapeutic effects without physical incision, removal, or trauma to the hemorrhoidal tissue
3Object-affected harmful factors
If medicated ointments and creams are used for hemorrhoids, then itching or inflammation may be relieved, but comprehensive relief and elimination of symptoms are not achieved
Solution Approach 1:
The invention replaces chemical medication application with electrical field therapy, using controlled current delivery to directly affect hemorrhoidal tissue through electrophysiological mechanisms rather than chemical action, aiming for more reliable symptom elimination

AI summary
A hemorrhoid treatment system includes a computing device, and a handheld device coupled to the computing device. The handheld device includes a probe electrode to contact a hemorrhoid on a patient that is to be treated. A grounding pad is to be coupled to the patient. The handheld device includes a variable resistance network, and a controller to sense a feedback voltage at a current sensing resistor in response to the probe electrode contacting the hemorrhoid and to the patient being grounded via the grounding pad. A level of current being delivered to the hemorrhoid is determined based on the sensed feedback voltage. Resistance of the variable resistance network is changed to adjust the output voltage to compensate for fluctuations in body resistance of the patient so that the level of current being delivered to the hemorrhoid matches a set level of current.
