Disposable Surgical Tissue Extraction Device with Integrated Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical devices for endoscopic procedures in distensible organs, such as the uterus, require multiple components and complex setups, leading to cluttered operating rooms and potential cross-contamination risks due to the need for separate disposal and sterilization of equipment.
Innovation Solution
A tissue resecting system that integrates a pump, filtration system, and cutting element into a compact handheld device with a footswitch, allowing for easy operation and minimizing equipment footprint, using a disposable portion for fluid and tissue contact and a reusable portion for drive components, which can be easily cleaned and reused.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate components are used for tissue resection and fluid management, then functional versatility is improved, but device complexity and operating room clutter increase
Solution Approach 1:
The patent combines the pump, filtration system, and cutting element into a single integrated handheld device. The pump and filtration system are merged into one housing, and the cutting element is integrated into the same handheld unit, eliminating the need for multiple separate components and reducing operating room clutter while maintaining all necessary functions.
Solution Approach 2:
The handheld device performs multiple functions including fluid suction, filtration, and tissue cutting within a single unit. The pump handles fluid management, the filtration system processes the fluid, and the cutting element performs tissue resection, making the device universally applicable for various surgical tasks without requiring multiple specialized instruments.
2Reliability
If separate disposal and sterilization equipment is used, then hygiene is improved, but equipment footprint and clutter increase
Solution Approach 1:
The device is divided into disposable and reusable portions. The disposable portion includes components that contact fluid and tissue (pump housing, filtration system), while the reusable portion includes the drive mechanism. This segmentation allows the disposable components to be easily replaced and disposed of after a single use, maintaining hygiene without requiring extensive sterilization equipment.
Solution Approach 2:
The pump and filtration system are designed as disposable components that can be easily replaced after each use. This eliminates the need for complex sterilization equipment and reduces the footprint of reusable equipment in the operating room, while still ensuring hygiene through proper disposal of contaminated components.
3Ease of operation
If a compact integrated design is used, then ease of operation and reduced clutter are improved, but device complexity increases
Solution Approach 1:
The device merges the pump, filtration system, and cutting element into a single handheld unit that is easy to operate. The integrated design allows the surgeon to control fluid management and tissue cutting with one device, improving ease of operation despite the internal complexity of combining multiple functions.
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 system reduces clutter in the operating room, enhances hygiene by allowing disposable components to be easily replaced, and reduces the need for extensive sterilization, while maintaining efficient tissue extraction and fluid recirculation, thus improving procedural efficiency and safety.
Implementation Method 1
The pump draws fluid, with suction, from an organ through the first fluid line

AI summary
Systems and methods discussed herein relate to surgical systems including tissue resecting devices where the handset has a disposable portion detachably coupled to a reusable portion. The reusable portion may be a housing where a motor and electronics are stored that may be used to drive a shaft inserted into the disposable portion. The shaft may be coupled to a fluid pathway through the disposable portion that is fluidly isolated from the reusable section. After use, the disposable section is detached from the reusable section and disposed, and the reusable section may be cleaned and sterilized, or may be cleaned only.
