Attacking bees: 3d printing surgical needle

When it comes to bees, most people think of nothing more than collecting honey and acupuncture at the first time, while foreign engineers have drawn inspiration from the bees' tail acupuncture. They used 3D printing technology to develop new types of surgical needles. They have studied the needle-like protrusions of insects such as wasps and mosquitoes, and finally chose the bees' stings as the basis for the new design.


The bees on the tail of the bee have barbed hooks. It will penetrate the skin relatively straight into the tissue, and this effect is exactly what the engineers want to achieve. They used a microscope to carefully observe the position of the needle and take it out for study.

The shape of the bees and stings is in full compliance with the requirements of the researchers. They want to create instruments that can reduce tissue damage while increasing accuracy. Inspired by bees and stings, they developed a design with small nicks or barbs on the needle. These barbs will reduce needle insertion and withdrawal forces, which helps to further reduce tissue damage.


"In general, surgical needles will bend when inserted into tissue due to their pointed design," said Hutapea. "The planned path of the needle on the way to the target, such as cancerous tissue or tumor, through this shape, the curve is limited - it is easier to control the robot setting, which is critical, because if the needle curve, you missed the target."

The next phase of the project is to focus on the materials needed to implement the design in the best way. The prototypes were put together using a polymer mixture, but the final needles required 3D printing with metal. Researchers believe that metal 3D printing technology is not yet at their desired level because they require metal needles with sub-millimeter dimensions and high aspect ratios.


At the same time, we are currently trying to achieve a compromise by researching and developing methods for manufacturing mixed metal polymer needles," said Hutapea. "We hope that within two or three years, we will have this technology. ”

Their goal is to eventually print these needles in 3D so that they can be used in surgical practice. The FDA approved the long road, but in the end they can see their bee-heuristic surgical needle in clinical applications to improve minimally invasive surgical procedures.

The two engineers published an article on their surgical needle design project at the journal Latest Invasive Therapy and Allied Technologies, Bioinspiration & Biomimetics. They will exhibit their work at Temple’s Franklin Institute as part of a temporary 3D print exhibition.
