DESCRIPTION OF THE PREFERRED EMBODIMENT The major components of the cartridge implant gun 10 are a body portion 11, a grip portion 12, a trigger member 13, a pellet cartridge 14, a cartridge holder 15, and a needle 16.
Within the body 1 l, is a plunger 20, which in its withdrawn position is wholly within the body 11 and in its extended position as shown in FIG. 4 extends the length of the needle 16. The plunger is controlled by operating lever 21 and plunger link 22. The operating lever is restrained by biasing spring 23 and is controlled by trigger link 24 connected to the trigger portion 13 which rotates around trigger pivot 26 causing the operating lever 21 to rotate about lever pivot thus controlling the position of plunger 20. The structure and operation of these mechanisms will not be further described as this portion of the implant gun is conventional.
Attached to the front of body portion 11 is the cartridge holder 15. The cartridge holder includes a front plate 31 and a threaded knob 32 having a bore or pellet conveying conduit axially aligned with the line of travel of the plunger 20. The needle 16 fits within the bore 33 and is held in place by threaded cap 34.
The cartridge holder also includes a rear plate 35 which contains a convenient means for mounting it to body portion 11 such as for instance a mounting cylinder 36 which may fit within the skin portion of body portion 11 and be attached by any convenient means. The rear plate may also conveniently contain a plunger guide 37 to hold the forward end of the plunger in its withdrawn position and to guide the plunger during its extension.
The rear plate may also have parallel cut out portions leaving a deformable section 38 of the plate containing a finger hold 39 and a cartridge bearing aperture 40.
The cartridge holder also has a left cover 41, a magazine spring pawl 42, and a right cover 43, thus leaving exposed the line of travel of the plunger 20 so that the operator during use can observe whether a cylinder of the cartridge is directly aligned and whether that cylinder contains pellets.
The pellet cartridge 14 is made of 3 pieces of molded plastic, a front plate 50, a magazine 60, and a rear plate 70.
The front plate 50 of the pellet cartridge includes a face flange 51 having apertures 52 which correspond to the magazine bores to be described. Each of the apertures has flexible fingers 53 which hold the pellet or pellets within the magazine until expelled therefrom by the plunger 20.
The front plate also has a tubular section 54 having an outer surface 55 which serves as a bearing surface for the magazine 60. The inner surface of tubular section 54 is a bearing surface 56 for the rear plate interrupted by spaced camming bevels 57.
The magazine 60 has an inner bore 61 which slides onto outer surface 55 of the front plate, and may also contain suitable locking lugs which, for clarity, are not shown on the drawings. The magazine also contains pellet cylinders 62 of which there are 24 on the magazine as disclosed. The rear section of the cylinder may have a slightly enlarged section 63 to guide the plunger through the cylinder and correct any minor misalignment of the magazine. The cylinder should also have an indent 64 associated with each cylinder to allow the initial registration of the magazine as hereinafter described.
The rear plate of the cartridge contains a rear flange 71 having apertures 72 which correspond to the cylinders of magazine 60. In each of the apertures are flexible fingers 73 to restrain the pellets. The rear plate contains an inner web 77 which is offset providing a bearing surface 74 cooperating with the bearing surface 56 of the front plate and interspersed with the bearing surface, locking fingers 75 cooperating with the camming bevels 57. At the inner end of the web is journal 76 which fits into the cartridge bearing aperture or bore 40.
OPERATION OF CARTRIDGE IMPLANT GUN To operate the cartridge implant gun, the operator selects a cartridge containing the proper pellets for the animals to be treated. A major advantage of this invention is that theoperator may rapidly change the cartridges if different animals are to be treated with different pellets. I
The operator bends back the flexible portion 38 of the rear plate 35 by inserting his finger in the finger hold 39. With the plate bent back he may then insert the pellet cartridge 14 and then release the flexible plate allowing the bearing 40 to hold the cartridge jour nal and the cartridge in position.
The operator then indexes the plate, the magazine spring pawl 42 indicating when the magazine cylinder is in register with the plunger and the bore or pellet conveying conduit in front of the cartridge. The operator may visually ascertain that the cylinder contains a pellet by viewing that cylinder through the aperture between the left cover 41 and the right cover 43.
The operator then inserts the needle into the animal to be treated and squeezes the trigger. The plunger passes through the cylinder, pushing the pellet or pellets through the bore and ultimately through the needle and into the animal. The needle may then be withdrawn before or after retracting the plunger. It will occasionally be desirable to insert pellets from successive cylinders in the same animal which can easily be done with this gun.
As shown in FIGS. 2, 3 and 5, the cartridge 15 is offset from the center line of the body of the gun. The offset, as shown, is adapted to a right handed user since he can observe the needle along the left side of the gun without the cartridge holder obstructing his view.
The cartridge implant gun and the pellet cartridge disclosed in this application have the further advantage of allowing pellets of varying sizes and numbers to be used with the same gun. The cylinder as disclosed will ordinarily accommodate from one to three cylindrical pellets but can accommodate other shapes such as spherical pellets. Likewise, the cylinder will accommodate a single smaller pellet thus affording considerable flexibility in use.
The foregoing is a description of the preferred embodiment of the invention as required by law. Other modifications of the described embodiment which fall within the invention as disclosed will be apparent to those having skill in the art.
