摘要： A hand actuated biopsy device comprises a vacuum generation mechanism and a tissue cutting mechanism manually actuated by a trigger of the hand actuated biopsy device. Hand manipulation or actuation of the trigger is used to power a vacuum pump to generate vacuum and to power the tissue cutting mechanism. The hand actuated biopsy device has a tissue piercing needle with a tissue receiving aperture. A tissue cutter translates and rotates within the needle and is powered by actuations of the trigger. When the needle is placed into tissue and the trigger is actuated to power the vacuum pump and the tissue cutter, tissue is drawn into the tissue receiving aperture and severed by the hand powered cutter. A tissue collection chamber can be attached to the hand actuated biopsy device to receive severed tissue samples within.

摘要： A biopsy device comprises a body and a needle extending distally from the body. The needle comprises a cannula and a tissue piercing tip that is unitary with the cannula. The tissue piercing tip may be formed by compressing the distal end of the cannula to put two distal cannula portions in apposition with each other. One of the apposed distal cannula portions may be removed. The remaining distal cannula portion may be formed into a blade of the tissue piercing tip. A cutter may be moved relative to the needle to sever samples from tissue protruding through a transverse aperture formed in the cannula. A gap may be provided between the exterior of the cutter and the interior of the cannula, permitting the cutter to be distally vented while a proximal vacuum is communicated to the cutter to transport severed tissue samples proximally through the cutter.

摘要： A biopsy device comprises a body, a needle, and a cutter. A self-reversing cutter translation mechanism translates the cutter proximally and distally in response to rotation of the cutter in a single rotational direction. The cutter translation mechanism comprises a lead screw with discretely formed threads and a rotatable pawl. The cutter is translated proximally when the pawl is in a first rotational orientation; and distally when the pawl is in a second rotational orientation. Resilient members cause the pawl to be rotated between the first and second rotational orientations when the cutter reaches a distal position and a proximal position. A vacuum draws severed tissue samples through the interior of the cutter to deposit the samples in a holder. The translation mechanism engages a valve mechanism to provide simultaneous venting to part of the needle and reversal of the pawl orientation when the cutter reaches a distal position.

摘要： A biopsy device includes a body having a cannula, a cutter positioned at least partly within the cannula, a tissue collection chamber, and a vacuum source. In one example, the biopsy device includes a cutter loader for rotating the cutter into a loaded position (e.g., open position). A trigger is engaged with a portion of the cutter loader and may be activated to allow the cutter to rotate back to a closed position. During this rotation, the cutter severs a tissue sample, which may thereafter be drawn through the cutter lumen into the tissue collection chamber under the influence of a vacuum created by the vacuum source. The vacuum source includes a piston configured to be operated by squeezing a scissors grip. A user may apply a single stroke or successive strokes to the piston to produce the vacuum.

摘要： A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder includes a rotatable manifold, and has a plurality of chambers that are each configured to separately hold tissue samples. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each of the chambers with the cutter lumen. A sensing system is configured to sense the rotational position of the manifold. A controller in communication with both the sensing system and the rotation mechanism is operable to control the rotation mechanism based at least in part on the position of the manifold as sensed by the sensing system. The sensing system may include a sensor in a fixed position and a rotating encoder wheel on a shaft that is used to rotate the manifold.

摘要： A biopsy device includes a cannula, a cutter disposed within the cannula, a needle hub having a gear for rotating the cannula, a mechanism for rotating and translating the cutter within the cannula, and a body portion. The cutter rotation and translation mechanism includes a first component that is secured to the cutter and a second component that is secured to the body portion. The body portion includes a tab that is configured to retain the axial position of the cannula and needle hub relative to the body until the tab is depressed or removed. The body is configured to permit the cannula and the needle hub to be pulled axially from the body only after the tab has been depressed or removed. The cutter can then be pulled axially from the body by unscrewing the first component of the cutter rotation and translation mechanism from the second component.
