Abstract
A TME surgical simulator is provided. The TME surgical simulator includes a simulated tissue layers and simulated vasculature and/or organ structures. The simulated tissue surgical simulator is adapted for but not limited to laparoscopic and/or transanal TME surgical procedures.
Claims17
A surgical simulator for a simulated surgical procedure, the surgical simulator comprising:
- a frame having a cavity, a proximal opening, and a distal opening;
- a plurality of simulated tissue layers disposed within the frame and attached, at least partially, to each other, wherein two or more of the plurality of simulated tissue layers are configured to define at least one dissection plane whereby the two or more of the plurality of simulated tissue layers are configured to be separable from each other,
- wherein one or more of the plurality of simulated tissue layers are configured with an outward tension away from an interior of the cavity of the frame to simulate insufflation, with a first simulated tissue layer of the one or more plurality of simulated tissue layers and a second simulated tissue layer of the one or more plurality of simulated tissues layers having differing outward tensions away from the interior of the cavity of the frame;
- wherein the plurality of simulated tissue layers comprise a simulated endopelvic fascia layer, a simulated mesorectum layer, and a simulated pelvic floor having an upper portion covering an upper portion of the frame and a lower portion attached to and covering a lower portion of the frame, the lower portion of the simulated pelvic floor extending from the proximal opening of the frame and extending beyond the distal opening of the frame;
- and wherein the simulated surgical procedure corresponds to a simulated total mesorectal excision (TME procedure.

A surgical simulator for a simulated surgical procedure, the surgical simulator comprising:
- a frame having a proximal end and a distal end;
- a plurality of simulated tissue layers disposed within the frame and attached, at least partially, to each other, wherein two or more of the plurality of simulated tissue layers are configured to define at least one dissection plane whereby the two or more of the plurality of simulated tissue layers are configured to be separable from each other, and wherein one or more of the plurality of simulated tissue layers are configured with an outward tension to simulate insufflation;
- and
- a balloon comprises silicone and fibrous material composite and contains a fatty fill, the balloon being attached circumferentially to other silicone-based simulated tissue layers of the plurality of simulated tissue layers and extending from the proximal end of the frame to the distal end of the frame, wherein the balloon has a proximal portion at the proximal end of the frame and a distal portion at the distal end of the frame, the distal portion of the balloon being larger than the proximal portion of the balloon.

A surgical simulator for a simulated surgical procedure, the surgical simulator comprising:
- a frame having a proximal end and a distal end;
- a first simulated tissue layer disposed within the frame;
- a second simulated tissue layer disposed within the frame and attached the first simulated tissue layer, the first and second simulated tissue layers being configured to define a dissection plane in which the first and second simulated tissue layers are configured to be separable from each other, at least one of the first and second simulated tissue layers being placed under circumferential tension;
- and
- a third simulated tissue layer attached to the first simulated tissue layer and to the distal end of the frame, the third simulated tissue layer being stretched towards an interior of the frame and attached to a simulated vessel and a simulated organ, wherein the third simulated tissue layer has an upper portion attached to and covering an upper portion of the frame and a lower portion attached to and covering a lower portion of the frame, the lower portion of the third simulated tissue layer extending from a proximal opening at the proximal end of the frame and extending beyond a distal opening at the distal end of the frame;
- wherein the first and second simulated tissue layers are both placed under circumferential tension and the first simulated tissue layer is circumferentially tensioned more than the second simulated tissue layer.
