Abstract
Devices and methods for cutting and collecting a specimen from a mass of tissue. The device may include an integrated cut and collect assembly. The integrated cut and collect assembly includes a cutting portion and a collection portion that includes a flexible membrane. The collection portion of the assembly is attached to the cutting portion thereof. The cutting portion is configured to cut the specimen from the mass of tissue and the collection portion is configured to collect the cut specimen and to encapsulate and isolate the cut specimen within the membrane to enable its safe retraction from the mass of tissue.

59. A method of cutting and isolating a specimen from a mass of tissue, comprising the steps of:
-
inserting an instrument that includes an integrated cut and collect assembly into the mass of tissue, the integrated cut and collect assembly including a cutting portion and a collection portion that includes, a thin flexible membrane, the collection portion being attached to the cutting portion, the cutting portion being configured to cut the specimen from the mass of tissue and the collection portion being configured to collect the cut specimen from the mass of tissue and to isolate the cut specimen from the mass of tissue within the membrane, isolating the specimen from surrounding tissue by cutting the specimen from the mass of tissue with the cutting portion and collecting the cut specimen within the flexible membrane of the collecting portion. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83)

84. A device for cutting and collecting a specimen from a mass of tissue, comprising:
-
a shaft defining a proximal and a distal end;
a work assembly near the distal end of the shaft, the work assembly being configured to cut the specimen from the mass of soft tissue and to isolate the cut specimen from surrounding tissue;
a single actuator near the proximal end of the shaft, the single actuator being mechanically coupled to the work assembly such that rotation of the device and operation of the single actuator is effective to cut, collect and isolate the specimen from the mass of tissue as the device is rotated. - View Dependent Claims (85, 86, 87, 88)

89. Method of collecting a tissue specimen from a mass of tissue, comprising the steps of:
-
inserting a surgical instrument into the mass of tissue to a target location within the mass of tissue, the instrument including a shaft and a work assembly near a distal end of the shaft, the work assembly being configured to controllably cut the specimen from the mass of soft tissue and to isolate the cut specimen from the mass of tissue within a tissue isolator;
controlling the work assembly of the surgical instrument to cut and isolate the specimen, and retracting the instrument from the mass of tissue while the specimen is isolated within the tissue isolator and at least partially trails the distal end of the shaft. - View Dependent Claims (90, 91)

92. A surgical instrument for retrieving a tissue specimen from a mass of tissue, comprising:
-
a shaft defining a proximal and a distal end, and a work assembly coupled to the shaft near the distal end thereof, the work assembly including;
a tissue cutting portion configured to cut the tissue specimen from the mass of tissue;
a tissue collection portion that includes a membrane, the membrane being configured to encapsulate and isolate the cut specimen from the mass of tissue and being adapted to stretch to enable the encapsulated specimen to at least partially trail the distal end of the shaft as the surgical instrument is retracted from the mass of tissue. - View Dependent Claims (93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107)
