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 first layer forming a substantially cylindrical tube having 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;
- a plurality of simulated tumor attached to the inner surface of the cylindrical tube along the longitudinal axis;
- and
- a plurality of second layers attached to the outer surface of the cylindrical tube in locations opposite to the plurality of simulated tumors.
A method for manufacturing a simulated tissue model, comprising the steps of:
- providing an elongated mandrel having an outer surface;
- rotating the mandrel;
- applying a first layer of uncured silicone on the mandrel;
- allowing the first layer to cure to form a substantially tubular structure having an inner surface and an outer surface;
- providing at least one simulated tumor having a size smaller than the first layer;
- attaching the at least one simulated tumor to a location on the inner surface of the first layer;
- providing at least one second layer of cured silicone having a size larger than the size of the at least one simulated tumor;
- and
- placing the at least one second layer on the outer surface of the first layer in a location opposite from the location of the at least one simulated tumor.
