Abstract

A surgical training model for simulating human prostate surgery may include a harvested porcine urethra. A harvested porcine vagina surrounds a portion of the harvested porcine urethra to define a simulated human prostate.

Claims (31)

1 . A surgical training model for simulating human prostate surgery comprising:

a harvested porcine urethra; and

a harvested porcine vagina surrounding a portion of the harvested porcine urethra to define a simulated human prostate.

2 . The surgical training model of claim 1 comprising a harvested porcine bladder coupled to the harvested porcine urethra adjacent the harvested porcine vagina.

3 . The surgical training model of claim 1 comprising a spacer between the harvested porcine vagina and adjacent portions of the harvested porcine urethra.

4 . The surgical training model of claim 1 comprising harvested porcine lateral connective tissue coupled to the harvested porcine vagina.

5 . The surgical training model of claim 1 comprising additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human vas deferens.

6 . The surgical training model of claim 1 comprising additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human seminal vesicle.

7 . The surgical training model of claim 1 comprising additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human vascular pedicle.

8 . The surgical training model of claim 1 comprising harvested porcine recto-sigmoid tissue adjacent the harvested porcine vagina.

9 . A tissue cassette for surgical training for simulating human prostate surgery comprising:

a body member configured to be removably coupled to a mannequin;

a harvested porcine urethra carried by the body member; and

a harvested porcine vagina carried by the body member and surrounding a portion of the harvested porcine urethra to define a simulated human prostate.

10 . The tissue cassette of claim 9 comprising a harvested porcine bladder coupled to the harvested porcine urethra adjacent the harvested porcine vagina.

11 . The tissue cassette of claim 9 comprising a spacer between the harvested porcine vagina and adjacent portions of the harvested porcine urethra.

12 . The tissue cassette of claim 9 comprising harvested porcine lateral connective tissue coupled to the harvested porcine vagina.

13 . The tissue cassette of claim 9 comprising additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human vas deferens.

14 . The tissue cassette of claim 9 comprising additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human seminal vesicle.

15 . The tissue cassette of claim 9 comprising additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human vascular pedicle.

16 . The tissue cassette of claim 9 comprising harvested porcine recto-sigmoid tissue adjacent the harvested porcine vagina.

17 . The tissue cassette of claim 9 comprising a body member mounting the harvested porcine urethra, and harvested porcine vagina.

18 . A method for making a surgical training model for simulating human prostate surgery comprising:

positioning a harvested porcine vagina to surround a portion of a harvested porcine urethra to define a simulated human prostate.

19 . The method of claim 18 comprising coupling a harvested porcine bladder to the harvested porcine urethra adjacent the harvested porcine vagina.

20 . The method of claim 18 comprising positioning a spacer between the harvested porcine vagina and adjacent portions of the harvested porcine urethra.

21 . The method of claim 18 comprising coupling harvested porcine lateral connective tissue to the harvested porcine vagina.

22 . The method of claim 18 comprising positioning additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human vas deferens.

23 . The method of claim 18 comprising positioning additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human seminal vesicle.

24 . The method of claim 18 comprising positioning additional harvested porcine tissue adjacent the harvested porcine vagina and configured to simulate a human vascular pedicle.

25 . The method of claim 18 comprising positioning harvested porcine recto-sigmoid tissue adjacent the harvested porcine vagina.
