Medical Insertion Device with Selective Energy Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical systems for delivering laser and electrical energy during procedures, such as for treating prostate issues, often require manual switching between devices to manage bleeding, which is time-consuming and increases procedural risks due to the need for multiple devices.
Innovation Solution
A medical system with a handle and delivery portion that includes a laser fiber and conductive wire, where a lock mechanism allows selective control of the movement of either the laser slider or the wire slider, enabling the same device to deliver both laser and electrical energy without the need for device changes, using a spring to bias distal movement and side arms to prevent simultaneous extension of both components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual switching between laser fiber and other energy delivery devices is performed to stop bleeding, then the ability to treat different tissue conditions is achieved, but the procedural time increases and the risk of injury increases
Solution Approach 1:
The patent combines a laser fiber and an electrical energy delivery wire within a single insertion device, allowing both energy delivery modes to be integrated in one tool. This merging eliminates the need to switch between separate devices, reducing procedural time while maintaining the versatility to treat different tissue conditions including bleeding control.
Solution Approach 2:
The insertion device is designed with multi-functionality, capable of delivering both laser energy and electrical energy through a single device. The lock mechanism enables the device to function in different modes (laser mode or electrical mode) as needed, providing universal treatment capability without requiring multiple specialized devices, thus reducing procedural time and complexity.
2Adaptability or versatility
If manual switching between laser fiber and other energy delivery devices is performed to stop bleeding, then the ability to treat different tissue conditions is achieved, but the risk of injury increases
Solution Approach 1:
By merging the laser fiber and electrical wire into a single insertion device with a unified lock mechanism, the patent reduces the number of manual interventions required. This integration minimizes the opportunities for user error and device-related complications, thereby reducing the risk of injury while maintaining adaptability to treat different tissue conditions.
Solution Approach 2:
The multi-functional insertion device allows the user to switch between laser and electrical energy delivery modes without removing or replacing the entire device. This reduces the risk associated with device changes, such as improper positioning or contamination, while still providing the versatility needed to address various tissue conditions including bleeding control.
3Adaptability or versatility
If multiple energy delivery devices are used to manage bleeding, then the ability to address different tissue needs is achieved, but the device complexity increases
Solution Approach 1:
The patent merges multiple energy delivery capabilities (laser and electrical) into a single integrated insertion device. This reduces the overall number of separate devices needed in the procedure, simplifying the procedural setup and reducing device complexity while maintaining the ability to address different tissue needs through the unified device's multiple functions.
Solution Approach 2:
By designing a universal insertion device that can perform both laser delivery and electrical energy delivery, the patent eliminates the need to manage multiple specialized devices. The lock mechanism provides a simple interface for switching between modes, reducing operational complexity while maintaining adaptability to address various tissue requirements including bleeding control.

AI summary
A medical system includes an insertion device including a handle and a delivery portion, a laser fiber, a conductive wire, and a lock. The laser fiber extends through the insertion device and is coupled to a laser slider to control a position of the laser fiber relative to a distal end of the delivery portion. The conductive wire extends through the insertion device and is coupled to a wire slider to control a position of the laser fiber relative to a distal end of the delivery portion. The lock is positioned within the handle and is movable in order to selectively lock either the movement of the laser slider or lock the movement of the wire slider.
