Abstract
Abstract In accordance with the present invention there is provided a biopsy device and method for the collection of at least one tissue sample from a surgical patient. The device includes a frame and an elongated piercing element attached to the distal end of the frame. The piercing element has a distal end, a proximal end and a lumen extending at least partially therethrough. The piercing element has a sharpened member at its distal end for piercing tissue, and a port proximal thereto which exposes the lumen. The device further includes an elongated cutter and tissue remover disposed coaxially and slidably within the lumen of the piercing element for harvesting a tissue mass disposed within the port of the piercing element and depositing the tissue mass proximal to the port for retrieval. Lastly, the device includes a mechanism for automatically axially rotating the piercing element after severing a sample so multiple samples can be harvested about a longitudinal axis of the piercing element without manually rotating the piercing element.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
137 words
A biopsy probe for collection of at least one soft tissue sample from a surgical patient, said biopsy probe comprising: a. a frame having a distal end and a proximal end; b. an elongated piercing element attached to the distal end of said frame, said piercing element having a sharpened distal end and a port proximal thereto for receiving a tissue mass; c. an elongated cutter disposed within said piercing element, for harvesting a tissue mass received within said port of said piercing element; and d. a device for automatically axially rotating said piercing after severing a sample, wherein said device for automatically axially rotating said piercing element is at least partially disposed on said cutter, and whereby multiple samples can be harvested about a longitudinal axis of said piercing element without manually rotating said piercing element.
Claim 2
Dependent Claim
137 words
A biopsy probe for collection of at least one soft tissue sample from a surgical patient, said biopsy probe comprising: a. a frame having a distal end and a proximal end; b. an elongated piercing element attached to the distal end of said frame, said piercing element having a sharpened distal end and a port proximal thereto for receiving a tissue mass; c. an elongated cutter disposed within said piercing element, for harvesting a tissue mass received within said port of said piercing element; and d. a device for automatically axially rotating said piercing after severing a sample, wherein said device for automatically axially rotating said piercing element is at least partially disposed on said cutter, and whereby multiple samples can be harvested about a longitudinal axis of said piercing element without manually rotating said piercing element.
Claim 3
Dependent Claim
22 words
The probe of claim 1 , wherein when said device is engaged, rotation of said cutter affects rotation of said piercing element.
Claim 4
Dependent Claim
35 words
The probe of claim 2 , further including a control unit for activating both the cutter, so that a tissue sample can be harvested, and said device so that said piercing element can be rotated.
Claim 5
Dependent Claim
43 words
The probe of claim 1 , wherein said cutter comprises an elongated tube having a cutting blade at a distal end of said tube, wherein said tube is axially and rapidly rotated and advanced distally within said port to harvest a tissue mass.
Claim 6
Dependent Claim
62 words
The probe of claim 4 , wherein said device for automatically axially rotating said piercing element comprises a first member disposed on said cutter, said first member cooperating with a second member which is connected to said piercing element, such that when said first and second members are engaged with each other, rotation of said cutter affects rotation of said piercing element.
Claim 7
Dependent Claim
34 words
The probe of claim 5 further including a control unit for activating both the cutter, so that a tissue sample can be harvested, and said device, so that said piercing element can be rotated.
Claim 8
Dependent Claim
138 words
A biopsy probe for collection of at least one soft tissue sample from a surgical patient, said biopsy probe comprising: a. a frame having a distal end and a proximal end; b. an elongated piercing element attached to the distal end of said frame, said piercing element having a sharpened distal end and a port proximal thereto for receiving a tissue mass; c. an elongated Cutter disposed within said piercing element, for harvesting a tissue mass received within said port of said piercing element; and d. a means for automatically axially rotating said piercing element after severing a sample, wherein said means for automatically axially rotating said piercing element is at least partially disposed on said cutter, and whereby multiple samples can be harvested about a longitudinal axis of said piercing element without manually rotating said piercing element.
Claim 9
Dependent Claim
138 words
A biopsy probe for collection of at least one soft tissue sample from a surgical patient, said biopsy probe comprising: a. a frame having a distal end and a proximal end; b. an elongated piercing element attached to the distal end of said frame, said piercing element having a sharpened distal end and a port proximal thereto for receiving a tissue mass; c. an elongated Cutter disposed within said piercing element, for harvesting a tissue mass received within said port of said piercing element; and d. a means for automatically axially rotating said piercing element after severing a sample, wherein said means for automatically axially rotating said piercing element is at least partially disposed on said cutter, and whereby multiple samples can be harvested about a longitudinal axis of said piercing element without manually rotating said piercing element.
