Integrated Hysteroscope and Biopsy Forceps for Simultaneous Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hysteroscopic examinations often require multiple instruments for uterine visualization and endometrial sampling, leading to discomfort for patients, prolonged procedure times, and increased costs due to the need for multiple instruments and complex equipment.
Innovation Solution
An integrated endoscopic apparatus with a light delivery system, electronic imaging module, and a side-facing sampling opening, allowing for simultaneous uterine visualization and tissue sampling without the need for repeated instrument insertion, featuring a handle with an integrated display and separate fluid paths for improved fluid flow and debris reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple instruments are used for hysteroscopy and endometrial biopsy, then diagnostic accuracy is improved, but patient comfort deteriorates and procedure time increases
Solution Approach 1:
The patent combines the hysteroscope and endometrial biopsy forceps into a single integrated instrument. The biopsy forceps are positioned within the hysteroscope shaft, allowing both visualization and tissue sampling functions to be performed through one instrument insertion, thereby maintaining diagnostic accuracy while improving patient comfort by eliminating repeated insertions
Solution Approach 2:
The integrated instrument serves multiple functions: the hysteroscope provides visualization of the uterine cavity while the integrated biopsy forceps enable tissue sampling. This multi-functional design allows a single instrument to replace what previously required separate instruments, resolving the contradiction between comprehensive diagnosis and patient comfort
2Measurement precision
If multiple instruments are used for hysteroscopy and endometrial biopsy, then diagnostic accuracy is improved, but procedure time increases
Solution Approach 1:
By integrating the biopsy forceps within the hysteroscope shaft, the patent enables simultaneous or sequential performance of visualization and biopsy functions without removing the main instrument. This eliminates the time loss associated with removing and reinserting separate biopsy instruments, thereby maintaining diagnostic accuracy while reducing total procedure time
Solution Approach 2:
The integrated design allows the hysteroscope to remain in place continuously while the biopsy forceps are deployed through its shaft. This continuous presence of the visualization instrument ensures that diagnostic examination can proceed without interruption, maintaining diagnostic accuracy while minimizing procedure time by eliminating repeated insertions and removals
3Measurement precision
If multiple instruments are used for hysteroscopy and endometrial biopsy, then diagnostic accuracy is improved, but equipment cost increases
Solution Approach 1:
The patent integrates the biopsy forceps within the hysteroscope shaft, combining what were previously separate instruments into one unified device. This integration reduces the total number of instruments that need to be purchased, stocked, and maintained, thereby reducing equipment costs while preserving the diagnostic capabilities of both visualization and tissue sampling functions
4Measurement precision
If repeated insertion and removal of instruments is performed, then tissue sampling is achieved, but patient discomfort increases
Solution Approach 1:
The biopsy forceps are nested within the hysteroscope shaft, with the forceps positioned inside the hollow shaft of the hysteroscope. This nesting arrangement allows the biopsy function to be accessed through the existing hysteroscope insertion, eliminating the need for separate instrument insertions and removals, thereby maintaining tissue sampling capability while significantly improving patient comfort
