FIRST ENTRY MODEL

摘要

A simulated abdominal wall model that is ideal for practicing laparoscopic first entry surgical techniques is provided. The model includes a simulated abdominal wall portion captured between two frame elements of a support. The support is connectable to a surgical trainer. When connected to the trainer, the model provides a penetrable abdominal tissue portion for accessing an internal cavity of the trainer. The simulated abdominal wall includes a plurality of layers including a skin layer, a fabric posterior rectus sheath layer, a simulated fat layer of low-resilience polyurethane foam and at least two layers that provide distinctive haptic feedback upon penetration of the simulated transversalis fascia and muscle layers. The simulated abdominal wall includes a simulated umbilicus across several layers of simulated tissue.

主权项

1. A simulated tissue structure, comprising:
a support; an artificial anatomical portion configured to simulate a region of an abdominal wall; the anatomical portion being connected to the support such that the anatomical portion is penetrable from a first side to a second side of the anatomical portion; the anatomical portion including a plurality of simulated tissue layers arranged in juxtaposition with each other; the simulated tissue layers including a simulated skin layer located above the remaining layers; each of the remaining layers having an opening extending through the layer; the simulated skin layer having a top surface and a bottom surface; the top surface of the simulated skin layer defines a first side of the anatomical portion; a tubular structure having a proximal end and a distal opening at a distal end; the distal end of the tubular structure extending through one or more openings in the remaining layers.
