Overview

Overview

Proprio is a surgical technology startup building Paradigm, an AI-powered platform, for spine surgery. Picasso expands Paradigm’s surgeon-controlled registration workflow, enabling surgeons to tell the Paradigm system what is the vertebral surface for registering a vertebra by tracing bone using a handheld probe and foot pedal.

I and my design partner redesigned the vertebra registration workflow. I partnered closely with the engineering and usability teams to ship a smooth experience with hardware, software, and audio components. Since Picasso's debut, I lead design enhancements for two additional sustaining software releases.

Partner Goals

Correct and sufficient data capture

Ensure that surgeons will trace sufficiently and correctly on vertebral bone to guarantee registration success.

Smooth hardware + software experience

Balancing usage of a foot pedal, surgical tools, and data shown on monitors is essential for optimal registration.

User Goals

Workflow efficiency

Allowing for refining a registration reduces the need for restarting the registration process.

Reducing mistakes

Visual, haptic, and audio feedback helps users make fewer mistakes when tracing - which means faster registrations.

Problem Statement

Problem Statement

Designing Picasso involved orchestrating a cohesive experience for spine surgeons and clinical specialists with multiple hardware components, a visible screen, and audio feedback while maintaining the efficiency of the surgical procedure.
