Tool for collecting a sample of animal tissue
First Claim
1. A tool for collecting a sample of animal tissue, comprising a first arm designed to cooperate with at least one cutting element designed to cut out a sample of animal tissue and one pusher element that is mobile relative to said cutting element and designed to push said sample of animal tissue into a storage element after cutting, and a second arm designed to cooperate with said storage element, the first arm comprising:
- a primary pin configured to transmit a motion of translation to said cutting element along an axis of translation in a direction of a sample of animal tissue, enabling the cutting element to cut out the sample of animal tissue disposed between the first arm and the second arm, until the cutting element abuts the storage element;
a secondary pin configured to transmit a motion of translation to said pusher element along said axis of translation in the direction of said sample of animal tissue, enabling the pusher element to push the sample up to the storage element;
at least one mobile coupling element; and
a housing;
wherein said primary pin and said secondary pin are configured to be mobile between a coupling position and a decoupling position;
wherein the movement of said cutting element and the movement of said pusher element are linked together in the coupling position, said at least one mobile coupling element being configured to be held within the housing in said coupling position;
wherein the movement of said cutting element and the movement of said pusher element are disassociated and move independently of each other in the decoupling position, said at least one mobile coupling element being configured to be released in said decoupling position; and
wherein said at least one mobile coupling element is a ball.

Abstract
The invention relates to a tool for collecting a sample of animal tissue, for interacting with collection mechanism including at least one cutting element capable of cutting out a sample and a pushing element movable with respect to the cutting element and capable of pushing the sample into post-cutting storage area. According to the invention, such a tool includes: a mechanism for driving the cutting element (21), a mechanism for driving the pushing element (23), and a mechanism for reversibly coupling the drive mechanism of the cutting element with the drive mechanism of the pushing element.
