Endoscope Handle With Detachable Housing For Fluid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopes face challenges in providing sufficient liquid supply and disposal during minimally invasive surgical interventions, particularly with long endoscope shafts, where the small diameter of the supply channel restricts the flow rate of rinsing solutions, impacting effective fluid delivery to the distal tip.
Innovation Solution
The endoscope features at least two separate and independent proximal connections for the working channel, allowing simultaneous insertion of surgical instruments and fluid supply/removal, eliminating the need for a separate supply/disposal channel, and enabling a larger diameter working channel without increasing the endoscope shaft's outer diameter. The connections include a large diameter for instrument insertion and a fluid-tight connection for fluid management, with a detachable handle design for easy cleaning and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a separate supply channel is used for fluid delivery, then fluid can be delivered to the distal tip, but the small diameter of the supply channel restricts the flow rate of rinsing solutions
Solution Approach 1:
The working channel is designed to serve multiple functions: it accommodates surgical instruments during procedures and simultaneously serves as the fluid supply channel. This eliminates the need for a separate supply channel, allowing the fluid channel to have a larger diameter for improved flow rate while reducing overall device complexity.
2Quantity of substance
If the working channel diameter is increased to improve fluid flow, then more fluid can be delivered, but the endoscope shaft outer diameter increases
Solution Approach 1:
By making the working channel multi-functional (both instrument passage and fluid supply), the fluid supply capacity is enhanced through its existing diameter without requiring an additional dedicated fluid channel, thus avoiding an increase in the endoscope shaft's outer diameter.
3Ease of repair
If the handle is made detachable for easy cleaning, then maintenance is simplified, but the connection between handle and shaft must be reliable
Solution Approach 1:
The handle is designed as a detachable component that can be separated from the endoscope shaft for easy cleaning and maintenance. The connection interface incorporates locking mechanisms and sealing elements that ensure reliable attachment during use while allowing convenient detachment for cleaning purposes.

AI summary
The invention relates to a handle for an endoscope, comprising a grip section (18) onto which a receiving housing (26) is moulded, preferably integrally, in which electrical and/or electronic components of a communication device are housed with an operating station of the endoscope, and on the outer face of which a control panel (16) preferably in the form of a keyboard or touch screen is arranged and electrically connected to said communication device. According to the invention, the communication device provides a cable-free connection to the operating station to which all functions of the endoscope, specifically optics and lighting, actuation of the bending section, injecting rinsing solutions or medication, or sucking up liquids, are or can be connected.
