GlobalSurgBox Components
(a) The GlobalSurgBox is a comprehensive surgical trainer that fits within a toolbox. (b) The lid holds all the necessary materials for building and performing the training modules. (c) A removable tray holds the necessary surgical instruments, including several different types of needle drivers, forceps, and scissors, while a removable wooden board located at the base of the toolbox serves as the foundation for individual training exercises.

Sample Modules
(a) The base of the simulator includes a wooden board (11 in x 3.5 in), nails (1.5 in), and an eye hook screw. This serves as the starting platform from which all modules are built using additional materials stored within the toolbox. (b) Medical student module #1 shows tying square knots with hair ties and a shoelace; #2 shows tying in a hole using a toilet paper roll and fishing line. (c) General surgery module #1 shows end-to-end vascular anastomosis using a linear balloon; #2 shows needle angle practice using hair ties. (d) Cardiothoracic surgery resident/fellow module #1 shows end-to-side coronary anastomosis using pipe-cleaners, alligator clip, and linear balloons; #2 shows aortic valve module using a cut cupcake holder placed inside a toilet paper roll.

Practicing With the GlobalSurgBox
(a) Suturing module: Nails are positioned on the wooden board in linear/triangular shapes. Hair ties are wrapped around the nails to simulate tissue. This allows the practice of forehand, backhand, and mattress suturing. These drills can be practiced with a full-length suture to learn suture spacing or a needle with only a small suture tail to hone needle angles and forceps agility. (b) End-to-side coronary/vascular anastomosis module: A balloon is stretched across 2 nails attached to the wooden board to simulate the target vessel, while a second balloon suspended by pipe cleaners and an alligator clip serves as the graft. Using a polypropylene suture, the anastomosis is started. The alligator clip can be tilted downward to simulate “parachuting” of the graft to the target vessel.
