Solution Overview
Problem
Existing electrosurgical medical devices often require time-consuming and inconvenient instrument exchanges during procedures, particularly when managing bleeding, as they lack integrated cautery functions.
Innovation Solution
An electrosurgical device with an elongated member that can be attached to an endoscope, featuring a distal portion that bends towards the longitudinal axis when extended, and includes an electrode exposed at the distal portion, allowing for cautery function without the need for instrument exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional instrument exchange method is used, then different surgical functions can be performed, but time consumption increases and procedural efficiency decreases
Solution Approach 1:
The patent combines multiple surgical functions (cautery, cutting, reaming, drilling) into a single integrated endoscopic instrument. The instrument housing includes multiple electrodes and cutting elements that can be selectively activated, eliminating the need to exchange between separate cautery instruments and other surgical tools during procedures.
Solution Approach 2:
The endoscopic instrument is designed as a universal device that can perform multiple surgical functions through a single attachment. The instrument housing accommodates various electrodes and cutting elements that can be switched or activated as needed, providing both cautery and other surgical capabilities without requiring separate dedicated instruments for each function.
2Reliability
If dedicated cautery instrument is used, then effective bleeding control is achieved, but instrument exchange time increases
Solution Approach 1:
The patent merges the cautery function with other surgical functions in a single integrated instrument. The instrument housing includes electrodes for cautery that can be activated alongside or independently from cutting and reaming functions, allowing the surgeon to maintain bleeding control without exchanging instruments when switching between surgical tasks.
Solution Approach 2:
The instrument is pre-configured with multiple electrodes and cutting elements positioned and ready for immediate use. The cauterizing electrode can be activated at any time without requiring instrument exchange, as it is already in place within the instrument housing, eliminating the time loss associated with exchanging dedicated cautery instruments.
3Ease of operation
If elongated member is extended beyond shaft, then electrode accessibility is improved, but device complexity increases
Solution Approach 1:
The patent employs a dynamic extension mechanism where the elongated member can be extended or retracted along the shaft as needed. The elongated member is configured to extend beyond the distal end of the shaft to provide electrode accessibility, then retract when not in use. This dynamic capability allows the device to adapt its configuration without requiring a permanently complex structure.
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 solution enables efficient control of bleeding during procedures by providing an integrated cautery function within the endoscope system, reducing instrument-swapping delays and improving procedural efficiency.
Implementation Method 1
The elongated member can include a distal portion that, when axially extended beyond a distal end of the shaft, bends toward a longitudinal axis of the shaft
Implementation Method 2
The electrosurgical device can include an electrode exposed at the distal portion of the elongated member... an electrical interconnect coupling the electrode to an electrosurgical energy connection
