Abstract

A system for interactively visualizing different options for tendon repair for a surgeon and for informing the surgeon in a descriptive way of the different options is disclosed. The system may be configured to determine the size of a damaged tendon and propose solutions consisting of the anchor types, number of anchors and a free tendon-to-bone healing area associated with each proposed solution. As such, the system may make a surgeon aware of solutions for which the surgeon was otherwise unaware that are superior in free tendon-to-bone healing area or number of anchors, or both. The system increases the likelihood that a patient will receive the optimum number of anchors and free tendon-to-bone healing area in a tendon repair.

First claim

We claim:

1. A tendon repair system, comprising:
a memory that stores instructions; and
a processor that executes the instructions to perform operations, the operations comprising:
receiving input of dimensions of a tear in a tendon;
generating a tear area size of the tear in the tendon based on the dimensions;
generating a number of tendon anchors that fit the tear area size;
generating a free healing area for the tendon to identify a superior free healing area, wherein the free healing area is an area not covered by the tendon anchors; and
generating output displayed on a graphical user interface to identify a superior number of tendon anchors and the superior free healing area.

2. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output comprising the number of tendon anchors that fit the tear area size.

3. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output comprising a particular type of tendon anchors that fit the tear area size.

4. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output comprising the free healing area for the tendon as an area not covered by the tendon anchors.

5. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output comprising multiple types of tendon anchors and the number of each type of tendon anchor needed.

6. The tendon repair system of claim 5 , wherein displaying output comprising multiple types of tendon anchors and the number of each type of tendon anchor needed comprises displaying at least one combination with multiple types of tendon anchors.

7. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output comprising a maximum distance between anchors.

8. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output comprising different repair techniques.

9. The tendon repair system of claim 1 , further comprising receiving a minimum distance between anchors.

10. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output that includes a graphical representation of at least one proposed solution.

11. The tendon repair system of claim 10 , wherein displaying output that includes a graphical representation of at least one proposed solution comprises displaying at least one graphical representation of a plurality of proposed solutions.

12. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output that includes at least one numerical and written description of a solution.

13. The tendon repair system of claim 1 , wherein generating output displayed on a graphical user interface comprises displaying output that includes a graphical representation, numerical and written descriptions of at least one proposed solution.

14. The tendon repair system of claim 13 , wherein displaying output that includes a graphical representation, numerical and written descriptions of at least one proposed solution comprises displaying output that includes a plurality of graphical representations, numerical and written descriptions of a plurality of proposed solutions.

15. A method for determining components to be used in a tendon repair surgery, comprising:
receiving input of dimensions of a tear in a tendon;
generating a tear area size of the tear in the tendon based on the dimensions; generating a number of tendon anchors that fit the tear area size;
generating a free healing area for the tendon to identify a superior free healing area, wherein the free healing area is an area not covered by the tendon anchors; and
generating output displayed on a graphical user interface to identify a superior number of tendon anchors and the superior free healing area.

16. The method of claim 15 , wherein generating output displayed on a graphical user interface comprises displaying output comprising the number of tendon anchors that fit the tear area size.

17. The method of claim 15 , wherein generating output displayed on a graphical user interface comprises displaying output comprising a particular type of tendon anchors that fit the tear area size.

18. The method of claim 15 , wherein generating output displayed on a graphical user interface comprises displaying output comprising the free healing area for the tendon as an area not covered by the tendon anchors.

19. The method of claim 15 , wherein generating output displayed on a graphical user interface comprises displaying output that includes a graphical representation of at least one proposed solution.

20. A non-transitory computer-readable device comprising instructions, which when loaded and executed by a processor, cause the processor to perform operations comprising:
receiving input of dimensions of a tear in a tendon;
generating a tear area size of the tear in the tendon based on the dimensions;
generating a number of tendon anchors that fit the tear area size;
generating a free healing area for the tendon to identify a superior free healing area, wherein the free healing area is an area not covered by the tendon anchors; and
generating output displayed on a graphical user interface to identify a superior number of tendon anchors and the superior free healing area.
