Brief:
Design is often neglected in the medical inventory.
Why would one need aesthetically pleasing instruments when technology is the fundamental key to surgical success? Why would one need a sculptural piece of patient aid when technology restores health?

 

This studio acts as a platform to discover a multitude of opportunities for innovation in medicine through the process of design, with exposure to Human-Centric Design Approach to harness a good problem scenario and an opportunity for design to intervene. The types of project may range from surgical instruments, physical simulators, rehabilitation tools, smart phone applications and others.

 

Project descriptions:

In the operating room, the attention and focus should be on the patient and the procedure. Everything else needs to function at its optimum efficiency. However, it is often a crowded and stressful environment, where minute mishap can lead to dire consequences, from the human factor to the machines and the environment.

​

In this project, we had the privilege of following Dr. O'Neill into the operating theatre to observe, identify potential pain points and areas for improvement, and propose some counter-measures.

Background:

​

We had the honour of being guest observers in 2 of Dr. O'Neill's operations: a general surgery and a orthopaedic (key-hole) surgery.

The issue:

​

We noticed an egregious pain point in the orthopaedic surgery, which is the tangled mess of cables on the instrument tray.

​

Orthopaedic surgery is a minimally invasive operation. Instead of a large skin laceration, a very small hole is made at the site of surgery to insert operating instruments through, one of which is a camera. The surgeon operates by seeing through the tiny camera and manipulating the various instruments. Therefore, this type of surgery heavily depends on long instruments with lots of cables and controls.

The length of the cables were not an issue. However, each of the cables was of different diameter, harness, and flexibility.

​

This created an entangled mess on the cable-instrument tray after just about 15 minutes into the surgery. The nurse had to constantly detangle the mess every few minutes.

The proposed solution:

​

An attachment to the surgical tray stand to hold the instruments and manage the cables.

Each attachment holds 1 instrument and could be connected to each other to form a rigid structure.
