Abstract

A surgical tool system for fitting an implant to a patient. The system includes a handpiece that is used to fit the implant. The handpiece is capable of reading data from a memory integral with the implant. The system includes a surgical navigation system capable of monitoring the position of the handpiece relative to the patient. Based on the data read by the handpiece from the memory of the implantable device and the data regarding the position of the implant the navigation system presents information regarding the procedure. This information includes data regarding the position of the implant relative to the patient or textual information based on the type of implantable device. If the implant is being improperly position, the surgical navigation system presents a warning or inhibits actuation of the handpiece.

Claims

1. A surgical tool system, said system comprising:

a handpiece capable of driving an implantable device that is applied to a patient, said handpiece including a coil for receiving signals from a memory integral with the implantable device that contain data describing the characteristics of the implantable device; and

a surgical navigation system including a monitor and being connected to said handpiece coil for receiving the data read from the memory of the implantable device, said surgical navigation system being configured to;

monitoring the position of said handpiece relative to the patient;

based on the position of said handpiece relative to the patient and the data read from the memory of the implantable device, determine the position of the implantable device relative to the patient; and

presents on said monitor information the relative position of the implant to the patient.

2. The surgical tool system of claim 1, wherein the surgical navigation system is further configured to, based on the data from the memory of the implantable device, determine if the implantable device is appropriate for the patient.

3. The surgical tool system of claim 1, wherein based on the data read from the memory of the implantable device, said surgical navigation system further presents on said monitor textual information about the procedure.

4. The surgical tool system of claim 1, further including an accessory attached to said handpiece, said accessory configured to fit the implantable device to the patient, and said accessory includes components through which the data signals from the memory of the implantable device are applied to said handpiece coil.

5. The surgical tool system of claim 1, wherein the types of implantable devices said handpiece is configured to apply to a patient include at least one from the group consisting of:

screws; and

reamers.

6. The surgical tool system of claim 1, wherein the surgical navigation system is further configured to:

based on the position of said handpiece relative to the patient and the data read from the memory of the implantable device, determine if the implantable device is being improperly positioned in the patient; and

if the implantable device is being improperly positioned, generate a warning.

7. The surgical tool system of claim 6, wherein:

said handpiece includes a power generating unit capable of driving the implantable device that is fitted into the patient;

actuation of said handpiece power generating unit is controlled by a control console; and

said surgical navigation system is connected to the handpiece power generating unit through said control console for regulating actuation of the power generating unit and is further configured to, if the surgical navigation system determines that the implantable device is being improperly applied to the patient, inhibits said control console from supplying energization signals to said handpiece power generating unit.

8. The surgical system of claim 1, wherein said handpiece comprises:

a body, wherein said handpiece coil is disposed in said body;

a power generating unit disposed in said body for driving the implantable device; and

a coupling assembly attached to said body for releasably engaging the implantable device to connect the implantable device to said power generating unit.

9. A surgical tool system, said system comprising:

a handpiece capable of driving an implantable device that is applied to a patient, said handpiece including a coil for receiving signals from a memory integral with the implantable device that contain data describing the characteristics of the implantable device; and

a surgical navigation system including a monitor and being connected to said handpiece coil for receiving the data read from the memory of the implantable device, said surgical navigation system being configured to;

monitoring the position of said handpiece relative to the patient; and

based on the data read from the memory of the implantable device, present on said monitor information about the procedure used to apply the implantable device to the patient.

10. The surgical tool system of claim 9, wherein said surgical navigation system is further configured to, based on the data from the memory of the implantable device, determine if the implantable device is appropriate for the patient.

11. The surgical tool system of claim 9, wherein the information said surgical navigation system presents on said monitor about the procedure comprises an image of the site where the implantable device is to be fitted and an image of the implant.

12. The surgical tool system of claim 11, wherein the information said surgical navigation system presents on said monitor about the procedure further includes text about the procedure.

13. The surgical tool system of claim 9, wherein the information said surgical navigation system presents on said monitor about the procedure is text about the procedure.

14. The surgical tool system of claim 9, wherein, based on the data describing the characteristics of the implantable device, said the surgical navigation unit determines if the implantable device is appropriate for the procedure being performed.

15. The surgical tool system of claim 9, further include an accessory that connects the implantable device to said handpiece, wherein an accessory is used into fit the implantable device to the patient, and said accessory includes components through which the data signals from the memory of the implantable device are forwarded to said handpiece.

16. The surgical tool system of claim 9, wherein the types of implantable devices from which the handpiece is able to read data signals includes:

screws; and

reamers.

17. The surgical tool system of claim 9, wherein said surgical navigation system is further configured to:

based on the data signals from the memory of the implantable device, determines if the implantable device is being improperly positioned in the patient; and

if the implantable device is being improperly positioned, generate a warning.

18. The surgical tool system of claim 17, wherein:

said handpiece includes a power generating unit capable of driving the implantable device that is fitted into the patient;

actuation of said handpiece power generating unit is controlled by a control console; and

said surgical navigation system is connected to the handpiece power generating unit through said control console for regulating actuation of the power generating unit and is further configured to, if the surgical navigation system determines that the implantable device is being improperly applied to the patient, inhibits said control console from supplying energization signals to said handpiece power generating unit.
