Medical Insertion Head With Pivot Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion heads for medical applications are cumbersome to handle and require complex maneuvers for inserting the insertion device into tissue, often necessitating the removal of a needle guard and involving increased volume and packaging size.
Innovation Solution
An insertion head with a base and a movably mounted insertion device that can pivot from a protective to an insertion position, facilitated by a handle with a movable second handle component that allows for single-handed operation, eliminating the need for manual manipulation of the insertion device and providing integrated protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the puncture needle and cannula are protruding from the insertion head, then the insertion device can be inserted into tissue, but the volume and packaging size of the insertion head increase considerably
Solution Approach 1:
The puncture needle is nested within the cannula, and both are received in a receptacle on the insertion head. The needle is stabilized by the cannula while the cannula is inserted into tissue, creating a compact nested structure that minimizes volume while maintaining insertion functionality.
Solution Approach 2:
The insertion device is designed to be movable relative to the base, transitioning from a protective position (where it is retracted) to an insertion position (where it protrudes). This dynamic configuration allows the device to be compact during storage and transport while providing full insertion capability when needed.
2Reliability
If a needle guard is detachably attached to protect against puncture injuries, then user safety is improved, but the device becomes more complex and removal becomes cumbersome
Solution Approach 1:
The protective function is merged into the base structure itself through a receptacle that receives and protects the puncture needle. This integration eliminates the need for separate detachable needle guards, reducing device complexity while maintaining protection against puncture injuries.
3Volume of moving object
If the insertion device is movably mounted on the base, then the insertion head becomes compact and easier to package, but the user must grasp the insertion head with one hand and pivot the handle with the other hand
Solution Approach 1:
The handle is divided into a first handle component fixed to the base and a second handle component that is movable. This segmentation allows the user to manipulate the insertion device independently while maintaining a compact overall structure, reducing the complexity of manual manipulation.

AI summary
An inserter for placing an insertion head, the insertion head comprising: i) a base with an underside that can be placed on organic tissue, ii) an insertion device that can be inserted into the tissue and is movably mounted on the base, iii) the insertion device being movable relative to the base from a protective position in which a free end of the insertion device is recessed behind the underside of the base to an insertion position in which the free end projects beyond the underside, iv) a handle projecting from the base with a first handle component and a second handle component movable relative to the base and the first handle component, and v) a coupling that transmits a movement of the second handle component into a movement of the insertion device.The inserter comprises a) an inserter housing (20) receiving a holding device, and a drive for the insertion head, wherein the drive includes a propulsion element which is arranged to be linearly movable in and against a propulsion direction V in the inserter housing and comprises a force generator, and b) means for moving the insertion device into an insertion position.
