Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum-based grasping devices for cervix handling in gynecological procedures are complex, uncomfortable for patients, and costly due to their multiple moving parts, which can cause pain and tissue damage and limit manufacturing efficiency.
Innovation Solution
A handheld gynecological device with a simplified design featuring a one-piece body member and a fixed rod member, utilizing a piston mechanism for vacuum generation and a single actuating mechanism to securely engage the cervix, reducing the need for multiple parts and minimizing thrust forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If vacuum-based grasping devices with multiple moving parts are used, then the cervix can be grasped more gently and comfortably, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent combines the vacuum chamber, piston mechanism, and cervix-grasping components into a single integrated body member. The vacuum chamber is formed within the body member itself, and the piston is received directly in this chamber, eliminating the need for separate vacuum pump units and multiple connecting parts while maintaining the gentle vacuum-based grasping function.
Solution Approach 2:
The body member serves multiple functions simultaneously: it provides the structural housing, forms the vacuum chamber, contains the piston mechanism, and directly engages the cervix through its distal end. This multi-functional design reduces the overall number of components needed in the device.
2Use of energy by moving object
If complex vacuum-generating mechanisms with multiple moving parts are operated during cervix engagement, then vacuum can be generated, but thrusting forces are unintentionally transferred to the cervix causing pain and tissue damage
Solution Approach 1:
The patent separates the vacuum generation function from the cervix engagement function in time and space. The piston is received in the vacuum chamber within the body member, allowing vacuum generation to occur independently without transferring thrusting forces to the cervix, which is engaged at the distal end of the same body member.
3Reliability
If devices with multiple moving parts are used, then vacuum grasping function is achieved, but manufacturing efficiency decreases and cost increases
Solution Approach 1:
The integration of the vacuum chamber and piston mechanism within the single body member structure significantly reduces the number of parts that need to be manufactured, assembled, and quality-checked, thereby improving manufacturing efficiency and reducing costs while maintaining the reliable vacuum grasping function.
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 device provides a more comfortable and efficient cervix handling experience with reduced risk of tissue damage, enhanced operational simplicity, and lower manufacturing costs by eliminating complex moving parts.
Implementation Method 1
a piston member being at least partially received in the vacuum chamber and configured such that at least a portion of the piston member is displaceable in the vacuum chamber from a first position to a second position for creating a vacuum in the vacuum chamber

AI summary
A handheld gynecological device for cervix handling is disclosed. The device includes a body member defining a vacuum chamber, and a piston member displaceable in the vacuum chamber from a first position to a second position for creating a vacuum in the vacuum chamber. The device includes an actuating member, and a rod member defining a lumen and a suction head. The rod member is fixed relative to the body member when the rod member is coupled thereto. The actuating member is coupled to the body member and/or the rod member and is configured to be switched from a disconnected position, in which the vacuum chamber is fluidly disconnected from the rod member lumen to a connected position, in which the vacuum chamber is fluidly connected to the rod member lumen.
