Abstract
Abstract An automated fine needle biopsy device is described for extracting tissue from the body predominantly in suspected cases of breast cancer. However, it can be used in other parts of the body accessible to needle biopsy. The device causes a fine needle, which is attached to the device, to reciprocate and/or rotate at the same time causing tissue to enter the needle. The depth and number of the thrusts can be pre-programmed, and the force behind each thrust is constant. Suction may or may not be used. The tissue extracted is subsequently expelled onto glass slides for microscopic interpretation. This device and method offer a vast improvement over the present method for fine needle biopsy wherein it is performed manually and in a very haphazard way.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
133 words
An automatic fine needle biopsy instrument for collecting a tissue sample comprising: a housing; a fine needle releasably attached to said housing and extending from said housing, said fine needle having a tip having an opening, wherein said fine needle is capable of being attached to and removed from said housing without opening sad housing; a motor positioned within or on said housing, said motor upon operation of the instrument being capable of providing said fine needle with reciprocating motion, whereby said fine needle is operative for penetrating tissue from which said tissue sample is collected and said opening of said tip is operative for collecting said tissue sample; and an electronic control means for controlling the operation of the instrument, wherein said electronic control means is positioned within or on the housing.
Claim 2
Dependent Claim
133 words
An automatic fine needle biopsy instrument for collecting a tissue sample comprising: a housing; a fine needle releasably attached to said housing and extending from said housing, said fine needle having a tip having an opening, wherein said fine needle is capable of being attached to and removed from said housing without opening sad housing; a motor positioned within or on said housing, said motor upon operation of the instrument being capable of providing said fine needle with reciprocating motion, whereby said fine needle is operative for penetrating tissue from which said tissue sample is collected and said opening of said tip is operative for collecting said tissue sample; and an electronic control means for controlling the operation of the instrument, wherein said electronic control means is positioned within or on the housing.
