Grommets (a pack of 3): grommets made of silicone which are positioned in the holes of the shell for the insertion of surgical tools. They have three functions:
1) A special shape tohook on to and to keep the components of the shell fastened together and in this way making the whole structure more secure, elastic and resilient. The grommets make it possible to assemble the structure without using screws or glue but simply by using a fixed joint.
2) It makes it possible to insert carbon trocar into the shell so that it is firmly fixed into the BUSHINGS thanks to a grip system. The grip system makes it possible to insert the rubber bands with the lower part of the structure in order to integrate the module Stitchy.
3)The shape and thickness of the rubber band shave been conceived in order to optimise these 3 functions.
