Apparatus for locating anatomic sites in brains of animals by radiography including means for holding the animals' heads

Claim 1

AN APPARATUS FOR HOLDING THE HEAD OF AN ANIMAL IN AN EXACTING AND UNMOVABLE POSITION WHILE OBTAINING LATERAL AND VERTICAL ROENTGENOGRAMS, SAID LATERAL AND VERTICAL ROENTGENOGRAMS BEING USED FOR LOCATING ANATOMIC SITES IN THE BRAIN OF SAID ANIMAL FOR INSERTION THEREIN OF PROBING MEANS, COMPRISING A HEAD HOLDING MEANS MOUNTED ON A RIGID BASE, SAID HEAD HOLDING MEANS HAVING A PLURALITY OF PIN MEANS, A PLURALITY OF SECURING MEANS TO SECURE SAID PLURALITY OF PIN MEANS IN A PREDETERMINED POSITION WHEN SAID PIN MEANS ARE ENGAGED IN INDENTATIONS IN OR FIXTURES MOUNTED ON THE SKULL OF SAID ANIMAL, LATERAL CASSETTE MEANS HAVING LOCATED THEREON COORDINATE AXES, FIRST ALIGNMENT MEANS FOR ALIGNING SAID LATERAL CASSETTE MEANS ON SAID RIGID BASE, VERTICAL CASSETTE MEANS HAVING LOCATING THEREON COORDINATE AXES, SECOND ALIGNMENT MEANS FOR ALIGNING SAID VERTICAL CASSETTE MEANS ON SAID RIGID BASE, A FIRST PROBE POSITIONING MEANS MOUNTED ON SAID RIGID BASE, SAID FIRST POSITIONING MEANS BEING MOVABLE ALONG AN AXIS PARALLEL TO THE LONGITUDINAL AXES OF SAID RIGID BASE, A SECOND PROBE POSITIONING MEANS MOUNTED ON SAID FIRST POSITIONING MEANS, SAID SECOND POSITIONING MEANS BEING MOVABLE ALONG AN AXIS PARALLEL TO THE TRANSVERSE AXES OF SAID RIGID BASE, A THIRD PROBE POSITIONING MEANS MOUNTED ON SAID SECOND POSITIONING MEANS, SAID THIRD POSITIONING MEANS BEING MOVABLE ALONG AN AXES PARALLEL TO THE VERTICAL AXES OF SAID RIGID BASE, HOLDING MEANS MOUNTED ON SAID THIRD POSITIONING MEANS AND MOVABLE ALONG THE LONGITUDINAL, TRANSVERSE AND VERTICAL AXES OF SAID RIGID BASE BY MOVEMENT OF SAID FIRST, SECOND AND THIRD POSITIONING MEANS, THE AXES OF SAID FIRST, SECOND AND THIRD POSITIONING MEANS BEING ACCURATELY PARALLEL TO THE COORDINATE AXES ON SAID LATERAL AND VERTICAL CASSETTES, A BENCHMARK HAVING ALIGNMENT MEANS THEREON FOR ALIGNMENT OF SAID BENCHMARK ON SAID RIGID BASE, SAID BENCHMARK HAVING INDICATING MEANS WHICH COINCIDE WITH RECTANGULAR AXES ON SAID LATERAL CASSETTE MEANS, AND A PROBING MEANS MOVABLE ALONG THE LONGITUDINAL, TRANSVERSE AND VERTICAL AXES OF SAID RIGID BASE BY FIRST, SECOND AND THIRD POSITIONING MEANS.

Claim 2

AN APPARATUS FOR HOLDING THE HEAD OF AN ANIMAL IN AN EXACTING AND UNMOVABLE POSITION WHILE OBTAINING LATERAL AND VERTICAL ROENTGENOGRAMS, SAID LATERAL AND VERTICAL ROENTGENOGRAMS BEING USED FOR LOCATING ANATOMIC SITES IN THE BRAIN OF SAID ANIMAL FOR INSERTION THEREIN OF PROBING MEANS, COMPRISING A HEAD HOLDING MEANS MOUNTED ON A RIGID BASE, SAID HEAD HOLDING MEANS HAVING A PLURALITY OF PIN MEANS, A PLURALITY OF SECURING MEANS TO SECURE SAID PLURALITY OF PIN MEANS IN A PREDETERMINED POSITION WHEN SAID PIN MEANS ARE ENGAGED IN INDENTATIONS IN OR FIXTURES MOUNTED ON THE SKULL OF SAID ANIMAL, LATERAL CASSETTE MEANS HAVING LOCATED THEREON COORDINATE AXES, FIRST ALIGNMENT MEANS FOR ALIGNING SAID LATERAL CASSETTE MEANS ON SAID RIGID BASE, VERTICAL CASSETTE MEANS HAVING LOCATING THEREON COORDINATE AXES, SECOND ALIGNMENT MEANS FOR ALIGNING SAID VERTICAL CASSETTE MEANS ON SAID RIGID BASE, A FIRST PROBE POSITIONING MEANS MOUNTED ON SAID RIGID BASE, SAID FIRST POSITIONING MEANS BEING MOVABLE ALONG AN AXIS PARALLEL TO THE LONGITUDINAL AXES OF SAID RIGID BASE, A SECOND PROBE POSITIONING MEANS MOUNTED ON SAID FIRST POSITIONING MEANS, SAID SECOND POSITIONING MEANS BEING MOVABLE ALONG AN AXIS PARALLEL TO THE TRANSVERSE AXES OF SAID RIGID BASE, A THIRD PROBE POSITIONING MEANS MOUNTED ON SAID SECOND POSITIONING MEANS, SAID THIRD POSITIONING MEANS BEING MOVABLE ALONG AN AXES PARALLEL TO THE VERTICAL AXES OF SAID RIGID BASE, HOLDING MEANS MOUNTED ON SAID THIRD POSITIONING MEANS AND MOVABLE ALONG THE LONGITUDINAL, TRANSVERSE AND VERTICAL AXES OF SAID RIGID BASE BY MOVEMENT OF SAID FIRST, SECOND AND THIRD POSITIONING MEANS, THE AXES OF SAID FIRST, SECOND AND THIRD POSITIONING MEANS BEING ACCURATELY PARALLEL TO THE COORDINATE AXES ON SAID LATERAL AND VERTICAL CASSETTES, A BENCHMARK HAVING ALIGNMENT MEANS THEREON FOR ALIGNMENT OF SAID BENCHMARK ON SAID RIGID BASE, SAID BENCHMARK HAVING INDICATING MEANS WHICH COINCIDE WITH RECTANGULAR AXES ON SAID LATERAL CASSETTE MEANS, AND A PROBING MEANS MOVABLE ALONG THE LONGITUDINAL, TRANSVERSE AND VERTICAL AXES OF SAID RIGID BASE BY FIRST, SECOND AND THIRD POSITIONING MEANS.
