Disposable Circumcision Apparatus with Bone Cutter and Glans Protector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circumcision methods are lengthy, require anesthesia, result in bleeding, and leave scars, making them inefficient and risky, especially in remote locations with high viral infection prevalence.
Innovation Solution
A disposable circumcision apparatus comprising modified bone cutting forceps and a penis head protection probe that allows for quick, painless circumcision without bleeding, using a bone cutter with a modified closing line and disposable parts to ensure minimal tissue damage and infection risk, and a cautery for hemostasis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional circumcision methods using scissors and clamp are used, then the procedure can be completed, but it takes about ten minutes or more and requires anesthesia
Solution Approach 1:
The patent extracts and removes the harmful elements of conventional circumcision by using a specialized device that eliminates the need for anesthesia, stitching materials, and complex surgical tools. The device performs the circumcision in a single action without requiring the patient to remain under anesthesia or require post-procedure stitching.
Solution Approach 2:
The patent employs a disposable circumcision device that is used once and then discarded, eliminating the need for sterilization of complex instruments and reducing the risk of infection. This single-use approach allows for rapid procedure completion without the time-consuming setup and cleanup of reusable surgical equipment.
2Reliability
If conventional circumcision with stitching is performed, then the foreskin can be approximated, but it causes bleeding, infection risk, and requires a second visit for stitch removal
Solution Approach 1:
The patent removes the harmful elements of stitching and wound approximation by using a device that creates a clean cut without requiring the edges to be brought together. This eliminates the creation of dead spaces where infection could occur and removes the need for foreign materials like stitches that could cause irritation or require removal.
Solution Approach 2:
The patent converts the potential harm of an open wound into a benefit by designing a cutting mechanism that simultaneously seals blood vessels and creates a clean edge that naturally heals without stitching. The device transforms what would be a harmful open wound into a controlled, clean incision that heals rapidly without infection risk.
3Productivity
If reusable surgical instruments are used, then the procedure can be performed, but sterilization is required and infection risk remains in remote locations
Solution Approach 1:
The patent employs a disposable circumcision device that is packaged sterile and used once, then discarded. This eliminates the need for complex sterilization procedures in remote locations and ensures that each device is sterile without requiring autoclaves or other sterilization equipment. The disposable nature guarantees infection prevention while maintaining procedure accessibility.
4Reliability
If central protection device and ring are used, then the circumcision can be performed, but dislocation causes bleeding, bad appearance, and requires second visit for removal
Solution Approach 1:
The patent removes the harmful elements of rings and protection devices by using a simple cutting device that does not require post-procedure removal. The design eliminates components that could dislocate, cause bleeding, or require a second visit for removal, achieving reliable circumcision completion without these harmful side effects.
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 apparatus enables a fast, bloodless procedure with minimal pain, no need for anesthesia or stitches, quick recovery, and reduced scarring, suitable for use by one person in various settings, including remote locations with high infection risk.
Implementation Method 1
the strong pressure that pushes the porous tissue and, makes the skin end closer to the end of the mucosa
Implementation Method 2
a cautery for hemostasis

AI summary
New disposable system devises and procedure for circumcision. The new procedure is by using the clamp in the same way of using bone cutter forceps, the penis marked by skin marker below the level of coronal sulcus, the prepuce retracted, a glans protector probe introduced above the glans, the prepuce pulled back over the probe, grasped by fingers on the probe to have painless holding. The modified bone cutter with blind cut end and groove on the upper surface is applied on the level of the skin mark. Light pressure separates the glans protector from its handle, then strong pressure on prepuce applies by this modified bone cutter, a sharp knife cuts the prepuce above the instrument, left a skin tag in the groove of the instrument, a heated oval shape stainless steel coated cupper cautery pass above the grove, the heating is by gas or electricity, but the electrical current must be cut off before application, the temperature between 140-300, glans protector removed no need for any dressing. Another modification is the removable disposable heads of the bone cutter. The result is very rapid circumcision with the lowest complication specially bleeding.
