The Stryker C-Mount, which attaches an endoscope to a surgical camera head, is one of a number of excellent couplers to be found within the Stryker product line. One can choose one or more of the three different C-mount models; the C-Mount, the Autocalvable C-Mount, and the Rotating C-Mount. The 1188 C-Mount endoclamp was designed with ergonomics in mind. It is constructed of durable aluminum and its main feature is a large, smoothly-rotating focusing ring that allows single-handed focusing. It is designed for use with the 1188 3-Chip HD Video System. Improved venting is one of the notable features of this coupler.
