Abstract

A marking device for defining the margins and orientation of radiography specimens includes a plurality of visually distinctive markers joined by a base that holds the markers until the markers are secured to a specimen. The base serves as a holder for the individual markers as the markers are secured to a specimen with sutures or staples, at which time the markers are disconnected from the base. One or more markers may be secured to a specimen as needed to define the orientation of the specimen. By securing markers to specific locations on a specimen, a surgeon can indicate to radiologists and pathologists the specimen'"'"'s orientation in the body before removal, thus aiding in future study of the specimen. Since the markers are made either wholly or partially from radiopaque material, the markers are visible when radiographed.

Claims

1. A device for margin marking of radiography specimens, comprising:

a base for gripping during use; and

a plurality of markers detachably fixed to said base, each marker defining an aperture for attaching the marker to a specimen and indicia visible when radiographed and indicative of orientation of the specimen.

2. The margin marking device set forth in claim 1, wherein each marker is fabricated from radiopaque material.

3. The margin marking device set forth in claim 2, wherein a plurality of the markers each comprises a peripheral surface defining a unique shape.

4. The margin marking device set forth in claim 1, wherein each marker defines a unique orientation relative to the other markers.

5. The margin marking device set forth in claim 1, wherein each of the markers defines a unique orientation, including (i) a first marker defining a cranial orientation;

(ii) a second marker defining a caudal orientation;

(iii) a third marker defining a medial orientation;

(iv) a fourth marker defining a deep orientation;

(v) a fifth marker defining a lateral orientation; and

(vi) a sixth marker defining a skin orientation.

6. The margin marking device set forth in claim 1, wherein each of the markers comprises indicia defined by at least one aperture.

7. The margin marking device set forth in claim 6, wherein each indicia includes characters indicative of a unique orientation.

8. The margin marking device set forth in claim 7, wherein each of the markers comprises a peripheral surface defining a unique shape and indicative of orientation.

9. A margin marker for radiography specimens comprising:

an aperture for attaching the marker to a specimen; and

indicia visible when radiographed and indicative of orientation of the specimen.

10. The margin marker set forth in claim 9, wherein the marker is fabricated from radiopaque material.

11. The margin marker set forth in claim 10, wherein each of the markers comprises a peripheral surface defining a unique shape indicative of orientation.

12. The margin marker set forth in claim 9, wherein the marker is radiopaque and defines an orientation consisting of at least one of the following:

cranial, caudal, medial, deep, lateral, and skin.

13. The margin marker set forth in claim 12, wherein each of the markers comprise indicia defined by at least one aperture.

14. The margin marker set forth in claim 13, wherein each indicia includes characters indicative of a unique orientation.

15. A method of marking the margins of a radiography specimen comprising the steps of:

providing a margin marking device having a base with at least one marker detachably fixed to the base, and wherein the at least one marker defines an aperture;

gripping the base and holding the marker against or adjacent to a respective marginal portion of a specimen;

securing the marker to the marginal portion of the specimen through the aperture and into the specimen; and

disconnecting the marker from the base and leaving the marker secured to the marginal portion of the specimen to indicate the orientation of the specimen.

16. The method of marking set forth in claim 15, wherein the securing element is at least one of a suture or a staple.

17. A method of marking the margins of a radiography specimen comprising the steps of:

providing a marker having indicia visible on a radiograph and indicative of orientation;

securing the marker to a marginal portion of a specimen corresponding to the respective indicia;

radiographing the specimen and marker attached thereto;

displaying on the radiograph the indicia to thereby show the orientation of the specimen.

18. The method of marking set forth in claim 17, wherein the securing element is at least one of a suture and a staple.

19. The method of marking set forth in claim 18, further comprising at least one of the following steps:

(i) securing a marker with indicia indicative of caudal orientation to the caudal margin of the specimen;

(ii) securing a marker with indicia indicative of medial orientation to the medial margin of the specimen;

(iii) securing a marker with indicia indicative of deep orientation to the deep margin of the specimen;

(iv) securing a marker with indicia indicative of lateral orientation to the lateral margin of the specimen;

(v) securing a marker with indicia indicative of skin orientation to the skin margin of the specimen; and

(vi) securing a marker with indicia indicative of cranial orientation to the cranial margin of the specimen.

20. A device for margin marking of radiography specimens, comprising:

first means for marking a marginal portion of the specimen;

second means for supporting the first means and for gripping during use;

third means for visually indicating the orientation of the specimen on a radiograph;

fourth means for detachably connecting the first means to the second means; and

fifth means for securing the marker to the marginal portion of the specimen.
