Surgical Pencil With Removable Light And Suction Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical procedures using electrosurgical pencils are hindered by the need for additional personnel to manage smoke, blood, and bodily fluids, and lack of adequate illumination at the surgical site, leading to increased costs and procedural complexity.
Innovation Solution
Integration of a removable lighting device with a surgical pencil, powered by a battery and featuring a mating mechanism for secure attachment, which can include LED or fiber optic lights, and an optional suction channel for managing fluids, allowing for improved visualization and reduced personnel requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional personnel are used to manage smoke, blood, and bodily fluids during surgical procedures, then the surgical site can be kept clear and safe, but the cost of the procedure increases and the complexity of the procedure increases
Solution Approach 1:
The patent combines the suction function with the electrosurgical pencil by integrating a suction channel through the pencil shaft, allowing the surgeon to simultaneously perform cutting/coagulation and suction operations with a single device, thereby eliminating the need for separate suction personnel and reducing procedural complexity
Solution Approach 2:
The electrosurgical pencil is designed to perform multiple functions: electrosurgical cutting, electrosurgical coagulation, and suction of smoke, blood, and bodily fluids. This multi-functional design allows one device to replace what previously required multiple devices and personnel, reducing both cost and complexity
2Reliability
If additional personnel are used to manage smoke, blood, and bodily fluids during surgical procedures, then the surgical site can be kept clear and safe, but the number of personnel required increases
Solution Approach 1:
The suction capability is merged into the electrosurgical pencil itself, allowing the surgeon to perform both electrosurgical operations and fluid/smoke removal with a single device, thereby eliminating the need for additional suction personnel
Solution Approach 2:
The surgeon uses the integrated suction channel to self-manage smoke, blood, and bodily fluids at the surgical site during the procedure, eliminating the need for dedicated personnel to perform this function
3Illumination intensity
If a removable lighting device is integrated into the surgical pencil, then surgical site illumination is improved, but the device complexity increases
Solution Approach 1:
The lighting device is merged with the electrosurgical pencil through a mating mechanism that allows the light source to be attached to the pencil shaft, providing localized illumination at the surgical site while maintaining the ability to separate the components for sterilization or replacement
Solution Approach 2:
The lighting system is designed as a separate, removable module that can be attached to or detached from the electrosurgical pencil. This segmentation allows the lighting component to be independently sterilized, replaced, or adjusted without affecting the main electrosurgical device
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 solution provides enhanced illumination and suction capabilities, reducing the need for additional personnel, improving surgical site visibility, and simplifying procedures by integrating lighting and suction functions directly into the surgical pencil, thus enhancing both surgical efficiency and patient comfort.
Implementation Method 1
The removable lighting device can include LED or fiber optic lights
Implementation Method 2
an optional suction channel for managing fluids
