Abstract

Disclosed herein is a virtual surgical table that that comprises a virtual anatomical model that can be manipulated or simulated via contact by the user and/or replica surgical tools. The table embodiment is useful for presurgical simulation, simulation during the surgery, teaching and training purposes. It is also useful for virtual surgery and dissection of human and other organisms.

Claims

1. A virtual surgical table that comprises a screen encasement, an interactive screen interface, a computer processor module, a memory component;

a virtual anatomical model comprised of segments of images stored on said memory component;

one or more computer program codes modules stored on said memory component, wherein the one or more computer program code modules enable the virtual surgical table execute one or more of the following operations;

(i) to display the virtual anatomical model or portion thereof,

(ii) to effectuate the creation of a virtual incision into the virtual anatomical model,

(iii) to move or stretch a portion of the virtual anatomical model,

(iv) to virtually cauterize a portion of the virtual anatomical model,

(v) to virtually apply forceps to a portion of the virtual anatomical model,

(vi) to virtually insert a catheter into a portion of the virtual anatomical model, or

(vii) to virtually insert a scope into a portion into the virtual anatomical model.

2. The virtual surgical table of claim 1, wherein the virtual anatomical model is derived from medical image data from a single subject.

3. The virtual surgical table of claim 1, wherein the interactive screen interface is responsive to contact by an operator.

4. The virtual surgical table of claim 1, wherein the creation of a virtual incision is responsive to a surgical tool replica that contacts and moves across the interactive screen interface, wherein the surgical tool replica is a scalpel.

5. The virtual surgical table of claim 1, wherein the creation of a virtual incision is responsive to a scalpel replica that moves across the interactive screen interface in proximity to the interactive screen but without contacting the interactive screen.

6. The virtual surgical table of claim 5, wherein said table comprises a sensor that senses an indicator associated with the scalpel replica.

7. The virtual surgical table of claim 6, wherein said interactive screen interface displays a structure corresponding to the scalpel replica when the scalpel replica is brought into proximity with the interactive screen interface.

8. The virtual surgical table of claim 7, wherein proximity with the screen interface comprises 3 feet or closer to the screen interface without touching.

9. The virtual surgical table of claim 1, wherein each operation step (II)-(vii) is mediated by contacting the screen interface directly, or is mediated indirectly through implementation of a surgical tool replica.

10. The virtual surgical table of claim 9, wherein contacting the screen interface directly is mediated by touch by a finger or hand of an operator.

11. The virtual surgical table of claim 1, wherein each operation step (II)-(vii) is mediated by directly, or is mediated indirectly through implementation of a surgical tool replica, without touching the interactive screen interface.

12. The virtual surgical table of claim 1, wherein a portion or layer of the virtual anatomical model is selectively transparent.

13. An article of manufacture comprising the virtual surgical table of claim 1, and a kit comprising at least one surgical tool replica that includes a contact surface for touching and/or sliding across the interactive screen interface without damaging the same.

14. The article of manufacture of claim 13, wherein at least one surgical tool replica comprises a scalpel, a catheter, forceps, an electrocautery instrument, scissors or an endoscope.

15. The article of manufacture of claim 13, wherein the at least one surgical tool replica is comprised of plastic, metal, glass, ceramic or wood, and a combination thereof.

16. The article of manufacture of claim 13, wherein the virtual surgical table includes a sensor that senses the at least one surgical tool.

17. The article of manufacture of claim 16, wherein the at least one surgical tool comprises an indicator.

18. The article of manufacture of claim 13, wherein the at least one surgical tool comprise a plurality of surgical tools and said virtual table senses a particular surgical tool when brought into proximity therewith.

19. A method of conducting a surgical simulation, said method comprising

obtaining a virtual surgical table according to claim 1;

and

effectuating one of the following operations on the virtual anatomical model;

(i) creating a virtual incision into the virtual anatomical model,

(ii) moving or stretching a portion of the virtual anatomical model,

(iii) cauterizing a portion of the virtual anatomical model,

(iv) applying forceps to a portion of the virtual anatomical model,

(v) inserting a catheter into a portion of the virtual anatomical model, or

(vi) inserting a scope into a portion into the virtual anatomical model
