Last year, DefProc worked with the Thackray Museum of Medicine in Leeds to carry out exhibit repairs on an interactive installation. The exhibit replicated a laparoscopy (keyhole surgery), allowing visitors to move graspers around inside a “body” and view what is happening through a video display. 

The challenge

This was the first time we had been asked to repair a museum interactive that we hadn’t designed ourselves. It was crucial that we understood the limitations of the museum display to improve the laparoscopy, making it more robust and fit for purpose.

The project

The primary fix was repairing the laparoscopy graspers. They had become misshaped, and the jaws no longer closed, limiting the laparoscopy’s interactive element. For museum installations, it’s crucial to reduce the maximum force anyone can put into the interactive elements to increase longevity. Seeing how the instrument was previously damaged allowed us to undertake preventive repairs to ensure that this wouldn’t happen again.

Inside the machine were soft polystyrene beads, representing blood inside the body. Some of these beads had been damaged by the graspers, so we replaced them with polyethylene beads that are more durable and can withstand being picked up by the graspers. We also added 3D-printed shapes inside the machine. For these, we played around with textures and functions to maximise interactivity, e.g. some of the pieces spin around when picked up by the graspers.

Our extensive experience working with museums for interactive displays and installations meant that we knew what was required to make the laparoscopy robust to withstand daily use by people of all ages and abilities. As well as improving user experience, we upgraded the internal part of the laparoscopy exhibit to prevent future damage. This included moving the camera and internal wiring so they would no longer interact. 

What’s next?

We’re always open to projects involving interactive installations. Whether our clients need exhibit repairs or upgrades, or fabricating something entirely new, we’re on hand to create something unique, practical and most importantly, fun!
