Abstract
A system for implanting a solid marker in an animal is provided. The apparatus includes a hollow tube having an entrance and an exit opening. A support is provided for supporting a hollow tube. A plunger is slideably disposed between a first position and a second position within the support. The plunger cooperates with the support and the tube. The plunger engages the marker proximate to the entrance opening of the tube, and ejects the marker through the tube when the plunger is moved from a first position to a second position.
Claims16
An apparatus for implanting a marker in an animal comprising;
- a hollow tubular means having an entrance opening and an exit opening, a sharp edge formed at the exit opening, support means configured to permit said tubular means to be releasably mounted in said support means, said support means includes a housing and a chamber in said housing, said chamber being adapted to receive said tubular means, and a cover slideably mounted to said housing and adapted to be disposed between a first position in which said tubular means can be inserted into said chamber and a second position wherein said tubular means is maintained securely within said chamber and projects from said housing;
- and a plunger means, slidably disposed between a first position and a second position, said plunger means cooperatively supported by said housing and adapted to enter said tubular means when said tubular means is maintained securely in said housing and is displaced from a first position to a second position and to engage said marker of said tubular means for ejecting said marker through said exit opening in response to said plunger means being coordinately displaced from said first position to said second position.
A needle assembly for use in an implanting apparatus including a hollow tube having an exit opening and an entrance opening, a marker positioned in said tube proximate to said entrance opening wherein said marker includes a coating thereon for defining an interference fit of said marker in said tube and a drive pin means disposed in said tube between said marker and said entrance opening for positioning said tube, said marker being a glass capsule and said coating being of a non-glass material.
A system for implanting a marker in a laboratory animal comprising an apparatus for implanting a marker in an animal including a hollow tubular means having an entrance opening and an exit opening, configured to permit said tubular means to be releasably mounted in said support means wherein said support means includes a housing and a chamber in said housing, said chamber being adapted to receive said tubular means, and a cover slideably mounted to said housing and adapted to be disposed between a first position in which said tubular means can be inserted into said chamber and a second position wherein said tubular means is maintained securely within said chamber and projects from said housing and a plunger means, slideably disposed between a first position and a second position, said plunger means cooperatively supported by said housing and adapted to enter said tubular means when said tubular means is maintained securely in said housing and is displaced from a first position to a second position and to engage said marker in said tubular means for ejecting said marker through said exit opening in response to said plunger means being coordinately displaced from said first position to said second position, and that can be grasped in an operator's hand, and an open cylinder adapted to receive and immobilize the head of an animal so that said instrument can be operated without difficulty.
An apparatus for implanting a marker in an animal comprising;
- a hollow tubular means having an entrance opening and an exit opening, a housing configured to permit said tubular means to be releasably held in said housing and a plunger means, slideably disposed between a first position and a second position, said plunger means cooperatively supported by said housing and adapted to enter said tubular means when displaced from a first position to a second position and to engage said marker in said entrance opening of said tubular means for ejecting said marker through said exit opening in response to said plunger means being coordinately displaced from said first position to said second position, and wherein said housing is configured to store said tubular means therein, said housing including an opening for permitting each said tubular means stored in said housing to be dispensed therethrough, wherein said housing means comprises at least a pair of opposed ramp means projecting from said housing, each said tubular means containing a pair of diagonally opposed grooves formed therein, said grooves being dimensioned to receive said ramps and position each of said tubular means in said housing and permit said tubular means to be dispensed through said opening one at a time.
