Device for transporting biological materials

Biological Material Transport Device

This technology features a capsule-type robot structure consisting of a body with multiple internal chambers and openings, and a magnetic drive unit that moves forward, backward, and rotates via an external magnetic field to press the transport mechanism of a selected chamber. Through the mechanical interaction between guide grooves and guide pins, it independently controls the protrusion of multiple transport mechanisms to perform the collection or delivery of biological materials.

Conventional in-vivo transport capsules rely on peristalsis, making active movement impossible, and lack the functionality to operate selectively while preventing cross-contamination during multiple sample collections or multi-material delivery.

This technology employs a selective drive mechanism where transport mechanisms are housed in multiple chambers arranged radially within the body, and a rod on the magnetic drive unit—movable and rotatable along a shaft via an external magnetic field—presses and extends a specific transport mechanism. Applicable to surgical robots, interventional systems, and medical automation, it improves the efficiency of collecting samples from specific locations within the digestive tract and enhances independent multi-picking and delivery capabilities.

Key Features:

• Multiple transport mechanisms housed in individual chambers for storing biological materials, capable of protruding outside the body through openings.
• A magnetic drive unit that moves within the body via an external magnetic field to selectively press one of the multiple transport mechanisms.
• A body with multiple openings formed on its rear surface and multiple chambers corresponding to each opening formed inside.
• A biological material transport device comprising a ring-shaped first magnetic body with a through-hole and a rod protruding from the first magnetic body toward the chamber housing the transport mechanism.
