Abstract
Simulated tissue structures for practicing surgical techniques and methods of manufacturing those structures are provided. In particular, a realistic organ model or simulated tissue portion for practicing the removal of a tumor or other undesired tissue followed by suturing a remnant defect as part of the same surgical procedure is provided. The simulated tissue structures include a polyp simulation having a suturable mesh layer that is separable from a defect layer. A simulated colon model with interchangeable and suturable tissue pods is also provided as is a fully suturable rectum model and a rectum model with integrative suturable and removable polyp zones.
Claims20
A simulated tissue model, comprising:
- a substantially cylindrical tube having a sidewall with an inner surface and an outer surface extending between a proximal end and a distal end and defining a central lumen having a longitudinal axis;
- wherein at least one of the proximal end and distal end is open;
- the cylindrical tube includes at least one aperture extending across the sidewall from the inner surface to the outer surface;
- and
- at least one pod sized and configured for insertion into the at least one aperture and in removable connection with the cylindrical tube;
- the at least one pod includes a cap and a simulated tissue portion connected to the cap;
- the cap includes a frame having a flange and defining an opening;
- the simulated tissue portion comprising at least one planar layer of silicone having an inner surface and an outer surface;
- the simulated tissue portion being connected to the flange such that the outer surface of the simulated tissue portion is connected to the flange and the simulated tissue portion spans the opening defined by the frame;
- the pod being removably connectable to the cylindrical tube such that the simulated tissue portion is aligned with the inner surface of the sidewall when connected to the cylindrical tube.
