Abstract

A portable surgical training device is provided. The trainer includes a top cover spaced apart from a base to form a simulated body cavity for locating model organs that are substantially obscured from the field of view of the user. The top cover includes a video display, fixed insertion ports and interchangeable inserts containing simulated tissue layers. The training device has open sides for demonstrating and training lateral surgical techniques including a simulated or live tissue colon attached to a support leg for simulating transanal minimally invasive surgery. A training endoscope with an adjustable focal length for use with the trainer and, in particular, with optical trocars is disclosed. The surgical trainer can be angled and is well suited for training laparoscopic surgery techniques and demonstrating surgical instruments.

Claims

1. A surgical training device, comprising:

a base;

a top cover having a top surface and a bottom surface;

the top cover being connected to and spaced apart from the base to define an internal cavity between the top cover and the base;

the top cover having a first opening;

a first insert having a top surface and a bottom surface;

the first insert being removably inserted into the first opening and removably connected to the top cover;

the first insert includes a second opening; and

a second insert being inserted into the second opening and removably connected to the first insert;

the second insert includes a top portion removably connected to a bottom portion to form an encasement having an opening in the top portion substantially aligned with an opening in the bottom portion;

the second insert further includes a removable insert material simulating human tissue disposed between the top portion and the bottom portion of the second insert providing a penetrable tissue simulation region for accessing the internal cavity;

wherein the insert material includes a plurality of layers; and

wherein the insert includes a first layer made of ethyl vinyl acetate foam and a second layer made of cellulose sponge.

2. The surgical training device of claim 1 wherein the first insert includes at least one insertion port extending across the top surface to provide access to the internal cavity;

the at least one insertion port being located adjacent to the second insert.

3. The surgical training device of claim 2 wherein the insertion port includes a seal.

4. The surgical training device of claim 1 wherein the insert further includes a third layer made of closed cell polyethylene foam.

5. The surgical training device of claim 4 further including a fourth layer of ethyl vinyl acetate foam;

wherein the third layer of closed cell polyethylene foam is located between the first layer and the fourth layer and the second layer is located above the first layer.

6. The surgical training device of claim 1 wherein the second insert includes a removable support ring disposed between the top portion and the bottom portion.

7. The surgical training device of claim 1 wherein the top portion of the encasement includes an upper ledge encompassing the opening in the top portion;

and the bottom portion of the encasement includes a lower ledge encompassing the opening in the bottom portion.

8. A surgical training device, comprising:

a base;

a top cover having a top surface and a bottom surface;

the top cover being connected to and spaced apart from the base to define an internal cavity between the top cover and the base;

the top cover having a first opening;

an encasement;

the encasement includes a top portion having a top opening connected to a bottom portion having a bottom opening;

the top opening being aligned at least in part with the bottom opening;

the top portion and the bottom portion defining a cavity therebetween;

the encasement further including a removable insert configured to simulate tissue;

the insert having a top surface and a bottom surface;

the insert being removably located inside the cavity of the encasement such that the top surface of the insert is accessible through the top opening and the bottom surface of the insert is accessible through the bottom opening;

the insert being supported inside the encasement such that the insert is penetrable across the top surface and bottom surface of the insert to access the internal cavity;

the insert includes a plurality of layers configured to simulate an abdominal wall;

wherein the insert includes a first layer having a top surface and a bottom surface and made of cellulose sponge;

a second layer having a top surface and a bottom surface and made of ethyl vinyl acetate foam;

a third layer having a top surface and a bottom surface and made of closed cell polyethylene foam;

a fourth layer having a top surface and a bottom surface made of ethyl vinyl acetate foam.

9. The surgical training device of claim 8 wherein the first layer is located above the second layer;

the second layer is located above the third layer; and

the third layer is located above the fourth layer.

10. The surgical training device of claim 9 further including a fifth layer having a top surface and a bottom surface and made of ethyl vinyl acetate foam;

the fifth layer being located above the first layer.

11. The surgical training device of claim of claim 9 further including a fifth layer having a top surface and a bottom surface made of ethyl vinyl acetate foam;

the bottom surface of the fifth layer overlaying the top surface of the second layer.

12. The surgical training device of claim 9 further including a fifth layer having a top surface and a bottom surface;

the fifth layer being located above the first layer;

a sixth layer having a top surface and a bottom surface made of ethyl vinyl acetate foam;

the bottom surface of the sixth layer overlaying the top surface of the second layer; and

a seventh layer having a top surface and a bottom surface and made of ethyl vinyl acetate foam;

the fourth layer being located above the seventh layer;

an eighth layer having a top surface and a bottom surface and made of closed cell polyethylene foam;

the bottom surface of the seventh layer overlaying the top surface of the eighth layer;

a ninth layer having a top surface and a bottom surface made of ethyl vinyl acetate foam;

the bottom surface of the eighth layer overlaying the top surface of the ninth layer.

13. The surgical training device of claim 12 wherein the first layer is yellow, the second layer is red, the fourth layer is red, the sixth layer is white and the seventh layer is white, the ninth layer is white.

14. The surgical training device of claim 8 wherein the top portion of the encasement includes an upper ledge encompassing the opening in the top portion;

and the bottom portion of the encasement includes a lower ledge encompassing the opening in the bottom portion.

15. The surgical training device of claim 14 further including a support ring sized and configured to fit between the upper ledge and the lower edge.
