Suture-Free Uterus Removal Manipulator for LAVH
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical devices for vaginal hysterectomies require significant surgical time and cause trauma due to the need for suturing the uterus for removal, which prolongs the procedure and increases patient discomfort.
Innovation Solution
A device with an elongated shaft, retractable barbs, a cervical cup, and an expandable balloon that allows for uterus manipulation and removal without suturing, using retractable barbs to secure the uterus during removal and an illuminable ring for improved visualization during colpotomy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suturing is used to secure the uterus for removal, then the uterus can be securely detached, but surgical time is prolonged and patient trauma increases
Solution Approach 1:
The patent extracts the suturing function from the uterus removal process by introducing a specialized manipulator device with a retrieval loop that can directly engage and extract the uterus without requiring sutures. The manipulator is inserted through the cervix, the loop is positioned around the uterus, and the uterus is pulled out through the vaginal canal, eliminating the time-consuming suturing step entirely.
Solution Approach 2:
The manipulator device serves as an intermediary tool between the surgeon and the uterus. Instead of directly suturing the uterus to detachment points, the manipulator with its retrieval loop acts as a mediator that grasps the uterus and facilitates its removal through the vaginal canal, thereby avoiding the need for traumatic suturing while reducing surgical time.
2Reliability
If suturing is used to secure the uterus for removal, then the uterus can be securely detached, but patient trauma increases
Solution Approach 1:
The patent eliminates the harmful suturing process by extracting the uterus through the vaginal canal using a manipulator with a retrieval loop. This direct extraction method avoids the need for sutures that cause tissue trauma, bleeding, and extended recovery time, thereby reducing patient trauma while maintaining secure uterus detachment.
Solution Approach 2:
The patent replaces the mechanical suturing system with a manipulation-based system. Instead of using needles and sutures to secure and detach the uterus, the manipulator uses a retrieval loop that mechanically grasps and pulls the uterus through the vaginal canal, substituting a less traumatic mechanical approach for the traditional suturing method.
3Ease of operation
If traditional manipulator devices are used, then uterus manipulation is possible, but uterus removal without suturing cannot be achieved
Solution Approach 1:
The manipulator device is designed with multi-functionality to address both uterus manipulation and removal. It includes a cervical cone for manipulation during surgery and a retrieval loop for removal without suturing. This universal design allows a single device to perform multiple functions that previously required separate procedures, enabling both easy manipulation and suture-free removal.
Solution Approach 2:
The manipulator device employs a nested structure where the retrieval loop is contained within the elongated shaft during insertion, and the cervical cone is positioned within the vaginal canal. The retrieval loop can be deployed from the shaft to engage the uterus, and the entire assembly works together to enable both manipulation and removal functions in a compact, integrated design.
