Gesture Controlled 3D Anatomical Visualizer V1.0
Description: Developing a computer vision interface that uses a standard laptop camera to track hand and fingertip movements and translate them into real time manipulation of 3D anatomical models. The system is designed to explore a contactless approach to interacting with anatomical visualizations, with potential applications in surgical environments where minimizing physical interaction with computers could be beneficial.
The current prototype uses hand landmark detection to control 3D model rotation through fingertip movement and zoom through a pinch gesture. The application supports OBJ models, with additional support for STL and PLY formats. Future versions will explore integration with full scale MRI and CT brain scans, higher performance rendering, and more advanced interaction with high resolution anatomical data.
Cable Driven Surgical Grasper
Description: Designed and modeled a hand held surgical grasper in SolidWorks, a 44 part assembly that borrows the core idea of a robotic surgical instrument. The hand works the handle, steel cables carry the motion down a long thin shaft, and a small bendable wrist points a pair of jaws that open and close. The design gives three controls: grip, wrist bend, and roll.
The handle holds the trigger, a gimbal mounted wrist lever, a rotation knob, and the cable anchors and tensioner. An 8.5 mm by 190 mm stainless shaft carries six cables, kept in separate lanes by PEEK spacers, and ends in a two axis wrist (pitch and yaw, up to 90° each way) and serrated jaws about 15 mm long. Materials were matched to each job, with titanium wrist links, hardened stainless jaws and pins, and PEEK bushings and cable guides.
Squeezing the trigger pulls a cable that slides a yoke at the tip, and a cross-pin on the yoke rides in an angled slot in each jaw to swing both open together, while a second cable around a small pulley pulls them closed. Each wrist hinge is driven by a pair of cables, and about 30° of lever tilt gives about 90° at the wrist. The rotation knob spins the shaft, wrist, and jaws together, and a cable tensioner takes up slack from the twist.
Intramuscular Autoinjector
Description: Designed and modeled an intramuscular autoinjector in SolidWorks, developing a detailed 9 part mechanical assembly based on the architecture of an existing autoinjector. The project explores the mechanical design of automated drug delivery systems, including needle protection, syringe stabilization, spring driven actuation, and trigger mechanisms.
The assembly was developed as 9 individual components: needle safeguard, needle stabilizer, needle, prefilled syringe, plunger, compression spring, spring housing and trigger assembly, end cap, and outer housing. Each component was modeled independently and assembled in SolidWorks to evaluate component fit, alignment, and mechanical interaction within the complete device.
