Advanced first entry model for surgical simulation
First Claim
1. A surgical training device, comprising:
- a laparoscopic trainer having a cavity and a floor for the cavity;
a penetrable simulated tissue structure having an upper surface and a lower surface and comprising at least one layer that simulates a tissue layer;
a receptacle connected to the simulated tissue structure;
the receptacle having a wall defining an interior of the receptacle;
one or more simulated organs located in the interior of the receptacle;
the one or more simulated organs being configured to be located proximate to the simulated tissue structure; and
a support configured to connect the receptacle to the laparoscopic trainer such that the receptacle is suspended above the floor of the cavity;
wherein the surgical training device is configured such that penetration of one or more of the simulated tissue structure and receptacle results in at least part of the one or more simulated organs inside the receptacle to translate distally away from the simulated tissue structure to simulate surgical insufflation of an abdominal cavity.

Abstract
The present invention provides a surgical training device for training laparoscopic first entry surgical techniques. The training device includes a simulated abdominal wall that is penetrable with an optical trocar. A receptacle containing a tissue simulation is located inside the receptacle. The tissue simulation is observable via scope placed inside the optical trocar. Upon penetration of the one or more of the simulated abdominal wall and receptacle, the tissue simulation appears to translate distally relative to the simulated abdominal wall. The distal translation is effected by a variety of ways including the release of negative pressure inside the receptacle upon penetration and the expansion of an elastic wall of the receptacle with the introduction of fluid under pressure into the receptacle.

17. A method for simulating surgical insufflation comprising the steps of:
-
providing a model comprising a penetrable artificial tissue structure configured to simulate an abdominal wall;
the model including a receptacle having a wall connected to the artificial tissue structure;
the model including at least one tissue simulation disposed inside the receptacle and located proximally proximate to the artificial tissue structure;providing a laparoscopic trainer having a cavity and a floor for the cavity; suspending the model above the floor of the cavity inside the laparoscopic trainer; moving an optical surgical obturator through the artificial tissue structure and into the receptacle; observing the at least one tissue simulation inside the receptacle through the distal end of the optical obturator; moving the at least one tissue simulation from a position proximal to the artificial tissue structure to a position relatively distal to the artificial tissue structure to simulate insufflation of an abdominal cavity. - View Dependent Claims (18, 19)
