Abstract

An implant injector having means for deposit of spaced implants wherein an inner housing member receives an outer housing member and a continuous channel is formed in the outer surface of the inner member, and the outer member has an inwardly projecting stud adapted to be received in said channel, said channel extending longitudinally of said inner member in spaced, connecting horizontal semicircular steps, which permit a plunger carried by said outer member to be moved in spaced advances as said outer member is actuated, moving an implant out of said inner member upon each forward movement of said plunger in said inner member.

Claims

1. In an implant injector having inner and outer members, said inner member having an axial passageway therethrough, a plunger on the outer member adapted to pass through said axial passageway of the inner member, a continuous channel in the surface of one of said members, divided into spaced, connecting semi-circular steps, means mounted in the other member adapted to be received and to travel in said channel as the plunger is moved through the inner member against implants therein.

2. The device defined in claim 1 wherein said semi-circular steps are separated from each other a distance calibrated with the lengths of each implant.

3. The device defined in claim 1 wherein indicia is formed on the inner member, calibrated with the longitudinal movement of said plunger, and a jacket on said outer member receives the upper end of said inner member, the lower end of said jacket covering one graduate of said indicia with each step of forward movement of said plunger.

4. The device defined in claim 1 wherein said outer member has a jacket on one end which fits over said inner member, and said means to be received by said channel on said inner member, projects inwardly from said jacket.
