Week 2

10.02.2025

The design of the socket was developed further and one socket with the velcro tape design was ready. 

 

 Other designs were studied and the scans for forearms were imported into Meshmixer to make a socket. Several YouTube videos were checked and used to make a layout of the component. So, the things learned:

• How to import the file into Meshmixer and clear the scan;
• How to create the socket that repeats the exact surface of the limb;
• How to polish and smoothen the surface of the part;
• How to convert the .obj file to part in Fusion 360.

Also, there was a problem with Meshmixer and another software as Blender was used to make a design of the socket. The background on prosthesis and 3D scanner was ready and the background on the scanner is under development.

Short meeting with the project manager.Several tasks were done such as: 

• Small adjustments were made to the draft design of the socket with velcro tape and it was sent to be printed on a 3D printer (Ultimaker). 
• The literature review was done such that information on position of the sensors/probe was studied and new articles were found (summarizing table was created). 
• The design of another socket with screws was developed further and modified in Meshmixer.

The first design was printed in a 3D printer and it turned out to be impractical as it was too hard to remove. 

   
So the initial design was modified and sent again to make a better fit.

 

The Tikiwiki website was studied and a menu was created. The background, literature review, Gantt chart, timeline and progress were added.The velcro tape was found on the internet and sent to the project manager to proceed with the purchase.

Meeting with the project manager where the results were presented and an ultrasound machine with the probes was demonstrated. Scanning process was shown and the US scans were studied.

The other design with the screws was ready and printed. However, the part for the screws was too thin and it is under modification too.

The tasks for the next week:

• Scan the wireless ultrasound probe Vscan Air CL to get the dimensions
• Import the scan into Fusion 360
• Create a support/socket for the probe (M4, M5 or M6 screws could be used)
• Integrate the support and the probe with the prosthesis’ socket design

For this the probe was scanned and the result was cleared in meshmixer to further work with it.

Development is ongoing for the Tikiwiki website and the probe’s socket design, with different configurations using screws and velcro tapes.
