1. In an apparatus for collecting animal or human tissue, said apparatus including a housing having an interior and an exterior, a curette having a tissue-scraping end and a passageway communicating with the housing interior and extending from said housing and terminating at a front end of the curette in a tissue-receiving opening, said housing acting as a handle for manipulating the apparatus, said housing having an outlet opening communicating with the interior of said housing and adapted to be connected to a source of vacuum for sucking tissue through said tissue-receiving opening of said curette and into said housing, the improvement wherein said housing is transparent along at least a portion of one longitudinally extending side thereof, and said housing having a substantially planar tissue collection screen inside said housing in the path of flow of said tissue to be drawn through said curette and into the housing, said screen extending longitudinally and obliquely of said housing for substantially the full length thereof, the screen having a multiplicity of tissue-screening apertures with inlet and outlet sides forming a communication between opposite laterally facing sides of the screen, said apertures being of such a size to catch the tissue being drawn through the housing and screen, the inlet side of the apertures on the side of said screen facing said longitudinally transparent portion of said one side of said housing, and the length of said housing being substantially greater than the lateral dimension thereof so that the obliquely extending screen which extends for substantially the full length of the housing has such a substantial longitudinal component that any tissue collected thereon is readily visible to the user looking laterally into the housing as he grasps the housing to manipulate the apparatus.
