US Patent 9070307 Surgical simulation device and assembly

A system for simulating a surgical procedure, which includes a housing covering an anatomical model. The model is made up of simulated tissue supported on a base assembly that allows pivoting and rotation of the simulated tissue. The simulated tissue includes a portion that represents soft tissue, such as dermal tissue, muscle, connective tissue and the like, and a portion that represents hard tissue, such as osseous tissue. The housing includes apertures through which a surgical instrument may be inserted for simulating a procedure on the simulated tissue. Cannulas may be set within the apertures.
