Abstract:
1. A device for sampling biological tissue, comprising: a tank containing a chemical product for treating a sample of biological tissue, the tank comprising a tank wall defining i) a lateral wall, ii) an adjoining base comprising a partition, iii) an opening located opposite the base and configured for filing the tank, and iv) an attachment part adjoining the base and ending with an orifice; a hollow needle with a continuous cavity that ends in a first opening at a first tip and in a second opening at a second tip, the first and second openings being in fluid communication with each other via the cavity, the first tip being held within an interior channel of the attachment part so that the needle extends out from the orifice, the needle, under pressure exerted on the second tip, being movable along a longitudinal axis of the interior channel of the attachment part so that said first tip moves towards the partition, wherein said hollow needle further comprises a cutting edge at said second tip configured to cut out the biological tissue to create a sample received in said cavity when the cutting edge at said second tip is pushed into the biological tissue, wherein said channel has dimensions that hold a proximal part of said hollow needle that carries the first tip, and wherein said partition is pierced by said first tip of said hollow needle after the sampling device is pushed into the biological tissue from the biological tissue exerting pressure on the second tip sufficient to move the needle along the longitudinal axis of the interior channel of the attachment part and so that said first tip moves towards and pierces the partition.
