Abstract
Abstract An appliance for the interstitial radiation of organs in the body of man or animals comprises a cannular tube which contains a radioactive compound and which is attached to the end of a rod provided with a handle. A sheath can be adjustably displaced along the cannular tube and rod and is arranged to tightly surround the tube and rod. The sheath is radiation-absorbing at least at the outer part, which can be brought to cover, more or less, the radioactive compound in the cannular tube.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
182 words
Appliance for interstitial radiation of organs in the body of man and animals, comprising an elongated hollow rod, a radioactive compound disposed within one end of said rod, a handle fitted on the opposite end of said rod, said handle having a screw-thread formed thereon, an elongated tubular sheath being in closely fitting relationship with and enclosing at least a portion of said rod and being axially displaceable thereon, said sheath being shorter than said rod, the end of said sheath adjacent the end of said rod containing said radioactive compound including a radiation-absorbing material extending for at least the length of the radioactive compound in said rod, the opposite end of said sheath being arranged in threaded engagement with the screw-thread on said handle for axially displacing said sheath relative to said rod for selectively uncovering any desired length of said rod containing the radioactive compound, and scale and index means cooperatively arranged on said handle and said sheath for indicating the axial length of said rod containing the radioactive compound which projects outwardly from the radiationabsorbing end of said sheath.
Claim 2
Dependent Claim
182 words
Appliance for interstitial radiation of organs in the body of man and animals, comprising an elongated hollow rod, a radioactive compound disposed within one end of said rod, a handle fitted on the opposite end of said rod, said handle having a screw-thread formed thereon, an elongated tubular sheath being in closely fitting relationship with and enclosing at least a portion of said rod and being axially displaceable thereon, said sheath being shorter than said rod, the end of said sheath adjacent the end of said rod containing said radioactive compound including a radiation-absorbing material extending for at least the length of the radioactive compound in said rod, the opposite end of said sheath being arranged in threaded engagement with the screw-thread on said handle for axially displacing said sheath relative to said rod for selectively uncovering any desired length of said rod containing the radioactive compound, and scale and index means cooperatively arranged on said handle and said sheath for indicating the axial length of said rod containing the radioactive compound which projects outwardly from the radiationabsorbing end of said sheath.
Claim 3
Dependent Claim
67 words
Appliance, as set forth in claim 1 characterized in that an outer plug being fitted into the end of said rod containing the radioactive compound, an inner plug positioned within said rod at the opposite end of the radioactive compound from said outer plug, and a spacer rod extending axially from said inner plug toward the opposite end of said rod on which said handle is fitted.
