Did you ever make boats, rockets, cranes, etc. out of paper when you were a kid? It's something that many of us have enjoyed doing. This wonderful Japanese art of paper folding is called 'Origami'. But you might be surprised to learn that this very simple, beautiful art is now being used to make major breakthroughs in medicine and save human lives. Today, we'll talk about this amazing connection.
So how does this art of origami help medicine?
Simply put, the basic idea of origami is to be able to fold something big into a very small size and then make it bigger again when needed. Imagine you are looking for a way to find
Doctors and engineers looked at this concept and thought: "Instead of making a large incision in the body during surgery, couldn't we make a device that could be inserted into the body through a tiny hole? Then, inside the body, it could be enlarged to the required size, and then crushed again and taken out when the job was done?"
This idea paved the way for today's minimally invasive surgery , or `` laparoscopic surgery .'' This method has allowed patients to recover quickly, with less pain, and without major scarring .
Amazing medical devices made using origami
Let's take a look at some of the devices that have already been built using this technology, or are in the research stage. Some of them look like they came out of a science fiction movie.
| Type of device | What it does | Origami connection |
|---|---|---|
| Heart Stent | When blood vessels in the heart become blocked, they are used to keep them open. | A stent, about 30 millimeters in size, is folded into a small size, about 7-9 millimeters, passed through a vein, and then extended at the desired location. |
| Oriceps | This is a small pair of forceps used in surgery. They are used for things like holding and cutting tissue. | It's like a 'hook' made of paper. After being inserted into the body through a small hole, this forceps can be activated internally. |
| Devices that destroy cancer cells | It is used to treat cancerous tumors in the stomach. This uses an electric current (radiofrequency ablation) to destroy cancer cells. | The tip of the instrument, which has many tiny spikes, is bent slightly when inserted through an endoscope. Inside the tumor, it unfolds into a 3D shape, like a peacock displaying its feathers. |
| DNA Origami (DNA Nanotechnology) | Research is being conducted to target drugs only to cancer cells and to use them for things like bioimaging, which is used to obtain images of the body. | Human DNA molecules are used like threads, 'twisted' into 3D shapes. These can 'pick up' a drug molecule and deliver it to the right cell. |
What are the special advantages of this method?
Origami-based medical devices have several advantages over conventional devices.
- Minimally invasive: As mentioned earlier, surgery can be performed through a small incision rather than a large incision . This results in less recovery time, less pain, and fewer scars.
- Simple design: These devices have fewer moving parts, pins, and joints , so there are fewer places for bacteria to accumulate and the risk of infection is reduced.
- Reduced production costs: Due to fewer parts, the cost of making these can be relatively low.
- Safety: Even surgical pouches can be made using origami. They can be unfolded so that the sterile surface does not come into contact with the non-sterile surface, which may contain germs .
Imagine, if you could perform surgery through a small incision instead of a large incision, how many fewer days would you have to stay in the hospital? How much faster would you be able to return to your normal life?
So aren't there any challenges in this?
There are indeed challenges. These are the two biggest challenges.
1. Choosing the right material: Origami is made of paper. However, an implantable device cannot be made of paper. They need to be made of special materials that are compatible with the body and do not cause adverse reactions (biocompatible materials).
2. Activation: How does the device, once inserted into the body, unfold at the desired location? Some devices are designed to unfold automatically when they reach body temperature. Some are activated by electricity or a small motor. This is something that needs to be done very delicately.
What will the future be like?
Universities and research institutes around the world are currently exploring the potential of origami for medical applications. For example, research is underway into making a foldable, thin sheet of paper that can be used to deliver anti-cancer drugs inside the body, or creating a stent as small as 0.5 millimeters to treat glaucoma .
Many of these technologies are still in the research stage, as it takes years to find funding, find a manufacturer, and obtain FDA approval to move from the lab to the point where they can be used in hospitals.
But most importantly, this simple art of paper folding has changed the way medical engineers look at the world. This is a perfect example of the limitless possibilities that can be achieved when art and science come together.
Take-Home Message
