Abstract
The invention provides a utensil (10) for extracting a sample of cerebral matter, particularly the brain stem from cattle, for laboratory analysis purposes, characterized in that it comprises a manipulation handle (12), at the front end of which is arranged a hollow part forming an extraction spoon (14), and the peripheral edge of which comprises at least one cutting portion (22, 26, 30) for cutting into the sample prior to its extraction.
Claims10
Utensil (10) for extracting a sample of viscera, particularly cerebral matter such as the brain stem located in the cranial cavity of cattle, for laboratory analysis purposes, characterized in that it comprises a manipulation handle (12), at the front end of which is arranged a hollow part forming an extraction spoon (14), and the peripheral edge of which comprises at least one cutting portion (22, 26, 30) for cutting into the sample prior to its extraction.
Utensil according to the preceding claim, characterized in that the peripheral edge of the spoon (14) comprises two longitudinal portions (22) parallel to the overall axis of the utensil and produced in the form of cutting portions.
Utensil according to any one of the preceding claims, characterized in that the peripheral edge of the spoon (14) comprises a transverse free end portion (26) roughly perpendicular to the overall axis (L-L) of the utensil (10) and produced in the form of a cutting portion.
Utensil according to the preceding claim, characterized in that the transverse cutting free end portion (26) has sawteeth (30).
Utensil according to any one of the preceding claims, characterized in that each cutting portion (22, 26, 30) is produced by virtue of a reduction in the thickness of the spoon (140) near its peripheral edge so as to produce a cutting filament.
Utensil according to any one of the preceding claims, characterized in that the concave side (16) of the spoon has at least one projection (34) intended to hold the sample in the spoon (14) while it is being extracted.
Utensil according to the preceding claim, characterized in that each projection (34) has an inclined front face (36) to make it easier for the utensil to be introduced forwards, and a transverse retaining rear face (38) which runs in a plane perpendicular to the longitudinal axis (L-L) of the spoon (14).
Utensil according to any one of the preceding claims, characterized in that, in cross section on a plane perpendicular to the longitudinal axis of the spoon (14), the concave face (16) thereof has a profile in the shape of an arc of a circle.
Utensil according to any one of the preceding claims, characterized in that it is made as a single piece by moulding of plastic.
