Single-Hand Control of Endoscope and Basket Retrieval Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical systems involving endoscopes and basket retrieval devices are cumbersome, requiring doctors to control both devices with separate hands, which can be burdensome during medical procedures.
Innovation Solution
A medical system comprising a medical device with a handle and a mechanism for moving a distal end, and an auxiliary medical device with a basket retrieval device that can be quickly attached to the medical device, allowing a doctor to grip and control both devices with a single hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the endoscope and basket retrieval device are separated and controlled by different hands, then each device can be controlled independently, but the procedure becomes burdensome and cumbersome requiring two hands
Solution Approach 1:
The patent combines the endoscope and basket retrieval device into a single integrated assembly where both devices are controlled through a common handle structure. The control mechanism integrates both the endoscope control elements and basket retrieval control elements, allowing the operator to manipulate both devices simultaneously with one hand, thereby reducing procedural burden while maintaining independent control capabilities
2Ease of operation
If the basket retrieval device is quickly attached to the endoscope, then single-hand control is enabled, but the attachment mechanism must be sufficiently secure
Solution Approach 1:
The patent divides the system into separable components including a handle assembly, endoscope, and basket retrieval device that can be quickly attached and detached. The segmented design incorporates quick-connect interfaces that provide secure mechanical coupling while allowing rapid assembly and disassembly, enabling single-hand operation when attached while maintaining the option for separate control when detached

AI summary
A medical system is provided comprising a medical device including a handle and a mechanism for moving a distal end of the medical device; an auxiliary medical device comprising a basket retrieval device including a basket sheath disposed over a basket wire and received into a working channel of the medical device; a knob assembly in communication with the basket retrieval device, the knob assembly rotatable so that the basket sheath, wire, or both move within the working channel; and a base removably connecting the auxiliary medical device to the handle wherein the handle and the base are configured to be simultaneously gripped with a hand, and wherein the mechanism is configured to be moved with a first finger to move the distal end of the medical device and the knob assembly is configured to be rotated with a second finger to move the basket sheath wire, or both.
