Solution Overview

Problem

Current endoscope/laparoscope holder systems require surgeons to pause surgery and use both hands to attach or detach the camera system, which is time-consuming and inefficient, especially when rotating the camera around the telescope axis for angled views or cleaning.

Innovation Solution

A novel easy attach-detach mechanism that allows surgeons to attach and detach the endoscope/laparoscope using one hand, featuring a fragmented fixed intermediate adaptor with a linear locking mechanism, return spring, and compression flange, enabling rotation around the telescope axis within a limited angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the endoscope/laparoscope is fastened to the holder using conventional mechanical fastening methods, then the attachment is secure and reliable, but the attaching and detaching process requires both hands and causes surgical interruptions

Engineering Contradiction:
Improveease of attachmentVSAvoidsurgical interruption time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The holder system performs the fastening action automatically through a spring-loaded mechanism that engages the endoscope/laparoscope with the holder without requiring manual intervention for the actual fastening, allowing the surgeon to attach the device using one hand while the mechanism secures it automatically

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A spring-loaded intermediate mechanism acts as a mediator between the surgeon's manual attachment action and the final secure fastening, where the spring automatically completes the fastening process after the surgeon initiates attachment, reducing the time and effort required

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the endoscope/laparoscope is securely fastened to the holder, then the position is stable during surgery, but the device cannot be easily detached for cleaning or repositioning

Engineering Contradiction:
Improveposition stabilityVSAvoidease of detachment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fastening mechanism transitions from a static friction-based connection to a dynamic spring-loaded connection that can easily transition between locked and unlocked states, allowing secure holding during surgery and easy release when needed by simply pressing a release mechanism

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fastening function is segmented into separate components: a spring-loaded locking mechanism and a release mechanism, allowing the device to be securely fastened during surgery and easily detached when needed without compromising either function

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the endoscope/laparoscope is rotated around the telescope axis for angled views, then the surgical field visibility is improved, but the rotation requires detaching and reattaching the device in conventional holders

Engineering Contradiction:
Improverotation capabilityVSAvoidtime for detachment and reattachment
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The holder maintains continuous engagement with the endoscope/laparoscope during rotation, allowing the device to be rotated around the telescope axis without detaching and reattaching, as the spring-loaded mechanism keeps the device securely connected throughout the rotation motion

Inventive Principle:
Principle #20Continuity of useful action

AI summary

The invention is an easy attach-detach mechanism (1) which allows for holding the endoscope/laparoscope (10) which is a camera system used in the minimally invasive surgical systems by means of a robot or a passive holder and when necessary allows for detaching the endoscope/laparoscope (10) easily from the holder and rotating around the telescope axis with a limited angle, characterized in that; it comprises the following; a fragmental fixed intermediate adaptor (12) which is mounted on the external surface of the endoscope/laparoscope (10) and is engaged with the main chassis (31) in the linear locking mechanism (30), a return spring (40) which is attached to a main chassis (31) on one end and is attached to a pressing arm with a cam mechanism (35) on the other end and applies upward pulling force to the cam press arm, a pressing arm with a cam mechanism (35) which transmits the upward force originating from the return spring (40) and the downward force originating from the surgeon to the compression flange (38), a compression flange (38) which transmits the upward movement originating from the return spring (40) force and the downward movement which is formed by the pressing force applied by the surgeon on the pressing arm with a cam mechanism (35) by means of the connecting pins (33) to the movable pot (32), a movable pot (32) which compresses the fragmental fixed intermediate adaptor (12) which it has contact with when a force originates from the return spring (40) into the main chassis (31) and prevents its motion therein and then allows the fragmental fixed intermediate adaptor (12) to rotate around the endoscope/laparoscope (10) telescope axis by means of releasing the adaptor (12) by moving in a downward manner as a result of the compression force originating from the surgeon, a barrier pin (41) which pushes away the fragmental fixed intermediate adaptor (12) and thus the endoscope/laparoscope (10) from the main chassis (31) by means of releasing from the movable pot (32) moving in the downward direction after the surgeon presses on the pressing arm with a cam mechanism (35) until it reaches the lower stopper pin (45), a compression spring (42) which is located behind said barrier pin (41) and enables the required force for the barrier pin (41) to push the fragmental fixed intermediate adaptor (12) away from the chassis (31).
