1. A specimen cutter comprising:
- a circular cutting tip for rotation about an axis for cutting a specimen out of a specimen sheet by rotation of said cutting tip and motion of said cutting tip axially toward a specimen sheet;
an electric motor connected to said tip for rotating said tip;
mounting structure for mounting said cutting tip within said specimen cutter to permit axial motion of said cutting tip with respect to said mounting structure in a direction away from the specimen sheet;
a force device connected between said mounting structure and said cutting tip to urge said cutting tip axially in the cutting direction so that at a predetermined force, said cutting tip axially moves in a direction away from the specimen sheet; and
a switch connected to said cutting tip and said mounting structure to be actuated by motion of said cutting tip with respect to said mounting structure, said switch being connected to said motor so that closure of said switch causes rotation of said cutting tip.

Abstract
The motorized specimen cutter has a replaceable rotary tubular cutting tip and a motor to rotate the cutting tip. Deflection caused by proper cutting force energizes the motor with enough energy to cut a specimen. A manually or automatically actuated ejector pin ejects the sample from the cutting tip.

17. A specimen cutter comprising:
-
a housing;
a tubular specimen cutter mounted with respect to said housing to rotate on an axis through said tubular cutter;
a motor mounted with respect to said housing, said motor being connected to rotate said tubular cutter;
a power supply connected to said motor to rotate said cutter, said power supply having sufficient power to rotate said cutter a sufficient amount to cut a specimen;
a first force sensor connected to said tubular cutter, said first force sensor being connected to said power supply and to said;
motor so that said power supply supplies power to said motor when adequate cutting force is sensed at said tubular cutter; and
a second force sensor, said second force sensor being connected between said power supply and said motor to disconnect said power supply from said motor when excessive force is detected at said tubular cutter.

18. A specimen cutter comprising:
-
a housing;
a tubular specimen cutter mounted with respect to said housing to rotate on an axis through said tubular cutter;
a motor mounted with respect to said housing, said motor being connected to rotate said tubular cutter;
a power supply connected to said motor to rotate said cutter, said power supply having sufficient power to rotate said cutter a sufficient amount to cut a specimen; and
an ejector rod positioned within said tubular cutter and there is an ejector motor connected to said ejector rod, an ejector switch connected to energize said ejector motor so that when a specimen is within said tubular cutter and said tubular cutter is positioned where it is desired that the specimen be ejected, said ejector switch can be actuated to actuate said ejector motor to cause said ejector rod to eject a specimen from said tubular cutter. - View Dependent Claims (19)
