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 marking the margins of tissue to be radiographed, comprising:

a base for gripping during use; and

a plurality of markers detachably connected to said base, wherein each marker defines an aperture for attaching the marker to the tissue and indicia, and at least one of the marker and indicia is at least partially radiopaque and thereby visible when radiographed to indicate orientation of the tissue.

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

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

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

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

7. The device set forth in claim 1, wherein the tissue is a tissue specimen to be removed from a body, and each marker is configured to mark a respective margin of the tissue specimen.

8. The 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 marker for marking the margins of tissue to be radiographed comprising:

a base and at least one marker detachably connected to the base, wherein the marker includes an aperture for attaching the marker to the tissue and indicia, and at least one of the marker and indicia is at least partially radiopaque and thereby visible when radiographed to indicate orientation of the tissue.

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

11. The marker set forth in claim 10, further comprising a peripheral surface defining a unique shape indicative of orientation.

12. The 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 marker set forth in claim 9, further comprising indicia defined by at least one aperture.

14. The marker set forth in claim 9, wherein the tissue is a tissue specimen to be removed from a body, and each marker is configured to mark a respective margin of the tissue specimen.

15. A method of marking the margins of tissue to be radiographed comprising the steps of:

providing a margin marking device having a base and at least one marker detachably connected to the base, and wherein the at least one marker defines an aperture and is at least partially radiopaque;

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

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

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

16. The method set forth in claim 15, wherein the securing step is performed with at least one of a suture and a staple.

17. A method of marking the margins of tissue to be radiographed, comprising the steps of:

providing a device including a base and at least one marker detachably connected to the base and having indicia visible on a radiograph and indicative of orientation;

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

disconnecting the marker and base;

radiographing the tissue and marker attached thereto; and

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

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

19. The method 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 tissue;

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

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

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

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

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

20. A device for marking the margins of tissue to be radiographed, comprising:

first means for marking a marginal portion of the tissue;

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

third means for visually indicating the orientation of the tissue 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 tissue, wherein at least a portion of at least one of the first and third means is at least partially radiopaque.

21. The device set forth in claim 20, wherein the first means is defined by a marker formed by a material that is at least partially radiopaque;

the second means is defined by a base including at least one surface for gripping during use;

the third means is defined by indicia;

the fourth means is defined by a frangible portion; and

the fifth means is defined by at least one aperture for receiving at least one of a suture and a staple.
