Abstract

A template for use in a surgical procedure is described. The template comprises a template body, means for fixing the template body to a patient'"'"'s tissue, a feature on the template body to indicate the appropriate location of the template body relative to an anatomical landmark, a feature on the template body to indicate the required location of a sensor which is to be implanted in the patient during the surgical procedure, and a feature on the template body for indicating the required location of a field generator which can be fixed to the template.

Claims

1. A template for use in a surgical procedure, which comprises:

a template body,

means for fixing the template body to a patient'"'"'s tissue,

a feature on the template body to indicate the appropriate location of the template body relative to an anatomical landmark,

a feature on the template body to indicate the required location of a sensor which is to be implanted in the patient during the surgical procedure,

a feature on the template body for indicating the required location of a field generator which can be fixed to the template.

2. A template as claimed in claim 1, comprising a plurality of removable strips of adhesive tape.

3. A template as claimed in claim 1, further comprising at least two sensor location features and at least two field generator fixation features.

4. A template as claimed in claim 1, wherein the template body has first and second limbs, the template body location feature being provided between the first and second limbs.

5. A template as claimed in claim 4, which includes a hinge region that facilitates relative pivoting movement between the first and second limbs.

6. A template as claimed in claim 4, which includes at least one sensor location feature and at least one field generator fixation feature on each of the first and second limbs.

7. A template as claimed in claim 1, wherein the feature on the template body for indicating the required location of a field generator includes means for fixing the field generator to the template.

8. An assembly for use in a surgical procedure, which comprises:

a template as claimed in claim 1,

a sensor that can be implanted in a patient, the sensor configured to generate external electromagnetic fields to indicate position data; and

a field generator for generating an electromagnetic field for the sensor.

9. An assembly as claimed in claim 8, wherein the field generator has fastened to it a quantity of one part of a hook and loop fastener material, and wherein the field generator fixation feature comprises a quantity of the other part of the hook and loop fastener material.
