A method and device for implanting large diameter objects subcutaneously or into the peritoneal cavity of bovines employs a beveled, puncturing, but substantially non-incising trocar.

Method and device for implantation of large diameter objects in bovines

A syringe assembly is comprised of a plunger, a syringe barrel having a cannula collar at one end of the barrel and an interior chamber within the barrel, a hollow cannula secured within the syringe barrel collar with the cannula extending axially from the collar to its distal end, a bore extending axially through the cannula and the syringe barrel collar, a segment of the bore decreasing (e.g., tapering) in diameter as it extends in a direction from the distal end of the cannula toward the barrel interior chamber, and a sheath removably attached to the syringe barrel and covering the cannula, the sheath being affixed to a center rod extending axially from the sheath into the bore at the cannula distal end and then seating in a sealing engagement with said segment of the interior bore.

An instrument for injecting implants through animal hide is comprised of an injector having a tubular body divided into two adjacent segments with a hollow interior bore extending through the segments of the body. The second segment of the body has a generally tapering configuration as it extends to the distal end of the body and is formed as a pair of laterally adjacent tines that extend longitudinally from adjacent the first body segment to the distal end of the body. One of the tines has a larger lateral width than a second of the tines at laterally adjacent cross sections of the tines, and one tine has a terminal end at the distal end of the body for making incisions through animal hide when employing the instrument in injecting implants. A push rod having a longitudinal length at least equal to the longitudinal length of the body is inserted through the interior bore of the body pushing the implant before it. As the push rod passes through the interior it forces the pair of tines radially away from each other thereby dilating the incision, and the push rod injects the implant into the livestock as a distal end of the push rod reaches the distal end of the body.
