Instrument for artificial insemination, embryo transfer or sampling follicular liquids in mammals
First Claim
1. An instrument for artificial insemination or embryo trannsfer by a transperitoneal and/or cervical route or for sampling follicular liquids in mammals, comprising:
- a hollow tubular sheath;
a piston movable in said sheath in an axial direction of the sheath and forming a fluid-tight seal within the sheath;
a rigid cover extending around the outer circumference of the sheath and along at least a part of the length of the sheath;
a needle attached to an anterior end of the sheath and extending past the anterior end of the sheath;
a handle attached to a posterior end of said sheath;
a rotary member located on said handle which cooperates with the piston so as to move the piston in the axial direction when the rotary member is rotated;
a palpator extending around the outer circumference of the cover, said palpator having a length which is greater than the length of the cover, but is less than the combined length of the sheath and the needle, said palpator being movable in the axial direction and being guided by said cover between a covered position where an anterior end of the palpator extends past an end of the needle, and an exposed position where the end of the needle extends past the anterior end of the palpator.

Abstract
An instrument of artificial insemination or embryo transfer by a transperitoneal and/or cervical route or for sampling follicular liquids in mammals especially horses, pigs, sheep, goats, deer and carnivores is of the type constituted by a syringe formed by a sheath in which slides in fluid-tight manner a piston movable in translation. The sheath is externally protected by a rigid cover and is immobilized in a manipulator sleeve comprising a rotary member adapted to actuate the piston. The anterior end of the sheath is fitted with a needle. The cover protecting the sheath is covered by and guides a palpator the length of which is greater than that of the cover but less than that of the sheath (including the needle). Thus the needle of the syringe is selectively covered or exposed in whole or in part by axial sliding movement of the cover.
