Abstract
A biopsy device is provided that includes a housing and relatively slidable tissue cutting and stylet members, both movable with respect to the housing. The members have actuators for manually moving the members and which are mounted in parallel relation to each other and when the proximal ends are equidistant from the housing, the cutting member covers a tissue receiving cavity in the stylet. The actuators are provided with stops to prevent the distal tip of the cutting member from moving distally beyond the distal tip of the stylet. A hand grip can be releasably attached to the device.
