Bosch Healthcare
Designing a surgery
BFA Thesis HfG 2017
20 Weeks
In cooperation with Bosch Healthcare Solutions I designed an innovative surgical instrument and the acompanied surgical process. The project focused on user centered design, involved a detailed on-site research to grasp needed information on usage and requirements, creating and evaluating ergonomically studies, developing feasible mechanical solutions as well as incorporating current design guidelines. Because of the new technology being used not only the instrument itself but the whole process was rethought from start to finish. The result was achieved in close cooperation with medical professionals as well as corporate designers and engineers of Bosch. Because of pending patents, the final result can't be shown until 2019.

„How does a surgeons' dream instrument look like?“

Intuitive

The most prominent requirement has been the intuitive handling of the instrument allowing for a theoreticaly blind usage.

Precise

A surgical instrument needs to live up to the surgeons abilities and provide the highest level of precise handling.

Ergonomic

Using and setting up the instrument needs to be simple and comfortable to allow for a flawless process.

On site analysis

Taking part in the surgical environment allowed for a detailed problem analysis and the setup of detailed requirements.

Market analysis

New instruments have to be based on or be closely related tn current usability concepts to prevent confusions and errors.

Ergonomic studies

The device needed to fit a wide range of professionals and demanded for a very obvious and easy to understand operation even for users who are not working with it on a daily basis.

Early prototyping

A modular system of handles and functional elements allowed for a quick and easy evaluation of the optimal structure.

Ergonomic validaion

Based on the modular system both ergonomics and the level of intuitive usability were easily analyzed.

User testing

Using 3D printing, first prototypes with basic functionality were made and used in user testings with different personnel.

Implementation

After the usability concept has been designed the inner component layout had to be evaluated based on different mechanical restrictions.

Form exploration

Through basic sketches the visual expression was created suiting the OR environment as well as the brand values.

„How can design help optimising the
process of a surgery?“

Preperation

Before the actual operation the operting room needs to be set up and instruments have to be moved to the sterile area.

Team work

The positive outcome of a surgery is much influences by the quality of teamwork. Supporting communication and easy interaction between the participants is crucial in the process.

Packaging

Space inside an OR is very limited, handling packagings can be a full time job involving both getting rid and also taking note of used equipment.

Pocess

During a complex surgery a lot of equipment is in use and steps need to be taken in a very strict manner. Creating and intuitive workflow and obvious choices helps simplifying the process.

Hygiene

Both objects and participants need to be sterile during the surgery which adds an extra level of complexity.

Follow up

The surgery itself won't end with the patient leaving the operating room. Taking care of used equipment as well as the aftercare of the patient involves a lot of action.

Simulated use test

In order to evaluate the designed surgery process, a simulated use test with medical professionals was set up.

Packaging

All instruments and objects needed during the surgery were divided into different packagings based on sterility and time of use.

Storage

To save space inside the OR a new packaging concept was developed, ensuring optimal long term storage but also reducing the on-site foot print.
