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

at least two legs spaced apart from each other and interconnecting and spacing apart the top cover and base to allow ambient light to illuminate the internal cavity;

one leg of the at least two legs having an aperture facing the internal cavity;

a tube configured to simulate a bowel having a proximal end and a distal end and a lumen extending between the proximal end and the distal end;

the proximal end of the tube being interconnected with the aperture such that the aperture provides an access port to the lumen of the tube;

the distal end of the tube extending into the internal cavity.

2. The surgical training device of claim 1 further including a sphincter insert configured to simulate an anus, having an opening and connected to the leg;

the opening of the insert being in communication with the lumen of the tube and configured to provide a realistic tissue-like interface.

3. The surgical training device of claim 2 wherein the insert is substantially annular in shape and the opening of the insert is circular;

the insert being inserted into the aperture of the leg such that the opening of the insert is coaxial with the aperture.

4. The surgical training device of claim 1 wherein the tube includes artificial tumors attached to the tube.

5. The surgical training device of claim 1 wherein the tube is adapted for insufflation such that the distal end of the tube is closed to contain insufflation gasses inside the lumen of the tube and the proximal end of the tube is sealed with a removable access device to prevent the escape of insufflation fluid;

the access device including an insufflation port for delivering insufflation gas into the tube.

6. The surgical training device of claim 1 wherein the leg includes a flat plate having an inner surface for facing toward the cavity and an outer surface facing outwardly toward a user;

the aperture being formed in the plate.

7. The surgical training device of claim 1 wherein the tube is configured to simulate an already inflated colon such that the tube is larger and distended as if it were insufflated with gas.

8. The surgical training device of claim 1 further including:

an aperture in the top cover;

wherein the leg is located along the periphery of the both the top cover and base and the tube is accessible through both the aperture in the top cover and the aperture in the leg.

9. 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 two legs spaced apart from each other and interconnecting and spacing apart the top cover and base to allow ambient light to illuminate the internal cavity;

one leg of the at least two legs having an aperture facing the internal cavity;

a tube configured to simulate a bowel having a proximal end and a distal end;

the proximal end being interconnected with the aperture such that the aperture provides an access port to the lumen of the tube;

the distal end of the tube extending into the internal cavity; and

wherein the tube is suspended from the top cover.
