Arthroscopy simulators are very sophisticated devices that help the surgeon to train. In addition these devices are not available to most surgeons, especially those who are just beginning.
1.2 What it will do?
The arthroscopy simulator is a device that helps traumatology residents. This allows training to perform arthroscopic knee surgery. This basically consists of a lower limb model that includes the knee and its internal structures (bones, meniscus). And the camera that will allow to observe the interior of the articulation.
1.3 Who will use it?
This is the use of traumatic doctors, such as training for attroscopic surgeries and joint pathologies of the knee.
2.Development of the final project
My project consists of two main structures:
Case of the camera (that allows the inner visualization of the knee)
The model of the lower limb (thigh and leg) that contains the knee joint.
2.1 3D design of camera
Arthroscopy cameras are devices that the surgeon uses to explore the inside of the knee during surgery.
In the end we obtained the 3D printing, where to contain the electronic card and the camera.
2.2 3D design and Making of Lower limb
2.2.1 3D design Bone
I decided to make a 3D impression from the images of the tomography. For this it was necessary to obtain the DICOM files. DICOM (Digital Imaging and Communications in Medicine) is the international standard to transmit, store, retrieve, print, process, and display medical imaging information (more about it).
3D Slicer is an open source software. This program allows editing and rendering of DICOM files (more about it).
Having the bones printed in 3D, I made a comparison with real bones. And there was not much difference between them.
To create the knee joint, need rubber. This material allowed me the stability and the elasticity to be able to mobilize the knee.
To create the outer covering that simulates the skin. I covered the model of the lower limb with pantyhose. Later I placed silicone on the pantyhose. This would give me the appearance of the skin (providing elasticity).
2.3 Electronics design of Final Project
2.3.1 Fabduino Desing
Using an Atmega328l microcontroller, I designed a circuit for the programming and control of LED's camera.
