First Claim
Patent Images
1. An apparatus for inserting a fiducial marker component into a patient, comprising:
- a housing that is generally cylindrically shaped and which has a bore provided therein, said housing having a proximal end and a distal end, at least a portion of the proximal end of the housing flaring outward from the body of the housing so as to provide an area for stably supporting the housing against a surface on a patient;
a cannula guide tube assembly that has a proximal end and a distal end and which contains a bore;
a drill for forming a bore hole at an implantation site; and
an inserter for inserting a fiducial marker component in the bore hole at the implantation site;
wherein the cannula guide tube is shiftable within said bore of said housing and the drill and inserter are each separately insertable into said guide tube and shiftable therein.

Abstract
The present invention provides a tool for inserting a fiducial marker. It comprises a housing and guide assembly, an obturator assembly, a drill for forming a bore hole at an implantation site, and a marker inserter for inserting a marker into the bore hole. The housing and guide assembly comprise a cylindrical housing having a bore provided therein, and a guide tube that is disposed and shiftable within the bore of the housing. The obturator assembly, drill and marker inserter are insertable in the distal end of the guide tube and shiftable therein.

13. An apparatus for inserting a fiducial marker component, comprising:
-
a housing defining an axially disposed bore, wherein the diameter of the bore is stepped so as to define a shoulder, said housing having a proximal end and a distal end, at least a portion of the proximal end extending laterally away from the bore so as to provide an area for stably supporting the housing against a surface; a cannula, said cannula having a proximal end, a distal end, an exterior surface and a shoulder attached to the exterior surface of the cannula between the proximal and distal ends of the cannula; and a spring located within the bore of the housing and bound at its ends by the bore shoulder and the cannula shoulder, wherein the cannula is freely shiftable within the bore so as to limit the length of the spring. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A tool kit for facilitating the insertion of a cylindrical object into a hole in a portion of anatomy of a patient, comprising:
-
a housing having two ends, one of which extends from the housing an amount sufficient to provide an area for stably supporting the housing against a surface on the patient; a spring-loaded cannula that is shiftable within the housing; a drill for forming a hole, said drill being shiftable within the cannula; and an insertion tool for driving a cylindrical object into the hole formed by the drill. - View Dependent Claims (36, 37, 38, 39, 40)
