OpenSurgiSim Psychomotor-AR module requires 3D printed modular bone parts which are supposed to be assembled together to form various different types of deformity bone cases to work on. This module also requires proper setup of webcam, webcam stand with a table clamp, two bone holder table-clamps and lighting for Augmented reality part to work on the 3D printed physical bone models which will be kept on the workspace table under the vision of the webcam.
Assembly of 3D printed parts[edit | edit source]
The 3D printed parts to be assembled can be directly downloaded from the home-page of the OpenSurgiSim Software after logging in the software. The 3D print can be done in either a FDM (Fused Deposition Modeling) or SLS (Selective Laser Sintering) printers. For SLS 3D printers, Nylon 12 powder material is preferable, as they are biocompatible and medical grade. For FDM 3D printers, ABS (Acrylonitrile-butadiene-styrene) filament material is preferable, as they are biocompatible and medical grade.
Preparation of the Workspace Area[edit | edit source]
Workspace Table[edit | edit source]
The workspace table should be a raised rectangular platform (height from ground - 80 to 100 cm) where a surgeon can stand and clearly see and easily work on the the assembled bone cases.
The rectangular platform should be large enough to place a computer system and to have free workspace area of at least 60 cm x 30 cm in dimensions.
The rectangular platform should have atleast two sides with overhang (atleast 10 cm) for fitting the two bone holder-clamps on the front edge and one webcam stand clamp on the lateral edge.
On the other two side of this rectangular workspace, the computer system or screen can be placed to access the OpenSurgiSim software while performing surgical procedure on the 3D printed bone cases.
Bone-holder Table clamps[edit | edit source]
The two 3D printed bone-stands in the assembly are fixed to the Workspace table by two cylindrical clamps. These cylindrical clamps are standard table clamps available in the market which have clamp on one side and a 10 mm diameter cylinder on the other side.
The cylindrical part of the two bone stands will go into the cylindrical part of the two clamps and tightened.
The clamp can be ordered from Amazon website at table-clamp link. If it is not available in your region, you can order any local clamp but it must have 10mm cylinder with positioning screw for tightening the bone-holder 3D part.
Webcam stand with clamp[edit | edit source]
The webcam stand with clamp is required for fixing the webcam at a reasonable height from the table so that workspace and assembled bones are clearly visible in the web camera.
This stand can be ordered from Amazon website at stand link. If it is not available in your region, you can order any local clamp, but make sure that the top part of the stand (where webcam is to be attached) should be at height of 50 to 60 cm approximately.
Web-camera[edit | edit source]
The webcam should capture videos at 720p or 1080p (HD quality) and transmit it to the computer system where openSurgiSim software is opened.
This webcam can be ordered from Amazon website at webcam link. If it is not available in your region, you can order any local webcam but ensure that the video capture quality of webcam is atleast 720p (1280x720 pixel resolution with 16:9 aspect ratio).
LED Light[edit | edit source]
The webcam-based augmented reality simulation in OpenSurgiSim software depends on the tracking of the assemble bones and the AR markers attached to these bones.
The tracking of all these components is better in good lighting conditions. Hence, this LED Light with USB is suggested to be attached to the computer system overseeing the workspace table. This can be ordered from Amazon website at LED link. If it is not available in your region, you can order any local LED light but ensure that the lighting is uniform and covers the workspace area completely.
