Surgical training model for laparoscopic procedures
First Claim
1. A surgical training device, comprising:
- a base;
a top cover connected to and spaced apart from the base to define an internal cavity between the top cover and the base;
at least one aperture or a penetrable region for accessing the internal cavity;
a laparoscopic camera insertable into the internal cavity;
a video display monitor configured to connect to an inserted laparoscopic camera and display images;
a removable model disposed inside the cavity;
the model comprising at least one simulated tissue portion connected to a plurality of mounting posts that are connected in spaced apart fashion to a base;
each mounting post includes at least one notch formed in the outer surface perpendicular to the longitudinal axis and configured to hold the simulated tissue portion in the location of the at least one notch such that the simulated tissue portion is suspended by a distance from the base;
wherein at least one mounting post is configured to angulate polyaxially with respect to the base and be movable with respect to the base in response to forces applied to the simulated tissue portion.

Abstract
A surgical training device includes a model comprising a simulated tissue portion mounted in selectable tension onto a plurality of posts connected to a base. Each post includes at least one notch configured for retaining the simulated tissue portion. Mounting the simulated tissue portion that is in the form of a sheet in notches of different heights creates an angled installation of simulated tissue upon which surgical techniques such as cutting and suturing can be practiced in a simulated laparoscopic environment. More than one sheet can be mounted and each sheet can be mounted with selectable tension by pulling the sheet more or less as desired onto the posts. One variation includes a simulated tumor disposed between sheets, angled or wobbly posts and textured and imprinted simulated tissue surfaces to provide various levels of dynamism and difficulty for surgical skills training in a laparoscopic environment.

12. A surgical training device comprising:
-
a base having an upper surface; a plurality of mounting posts connected to the base and extending upwardly from the upper surface of the base;
each mounting post has a proximal end connected to the base and a tapered distal end;
the proximal end is connected to the base;at least one substantially planar simulated tissue portion having an upper surface and a lower surface;
the simulated tissue portion includes apertures extending between the upper surface and the lower surface;
the mounting posts are configured to pass through the apertures such that the simulated tissue portion is suspended by the posts extending through the apertures;
the simulated tissue portion is made of flexible and stretchable materialwherein each mounting post includes at least one notch formed in the outer surface perpendicular to the longitudinal axis and configured to hold the simulated tissue portion in the location of the at least one notch such that the simulated tissue portion is suspended within the notches and retained in the notches along the mounting posts and prevented from moving along the length of the mounting posts. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
