Patent ID: 7824359

Claim:
A bioinjection device, comprising: a housing having an upper portion and a lower gripping portion, the lower gripping portion having a handle member and a trigger member, the trigger member being pivotally attached to the handle member, the upper portion of the housing having an open interior region defined therein; a shaft slidably mounted in the open interior region of the upper portion of the housing, the shaft having a channel formed therethrough, the shaft having opposed forward and rear ends; at least one lever arm having first and second ends, the first end being attached to the rear end of the shaft, the second end being attached to the trigger member so that rotation of the trigger member with respect to the handle member drives sliding translation of the shaft with respect to the upper portion of the housing; a needle slidably received within the channel formed through the shaft, the needle having opposed front and rear ends, the rear end of the needle being attached to the at least one lever arm so that rotation of the trigger member with respect to the handle member drives forward sliding translation of the needle with respect to the upper portion of the housing and the shaft; a retaining member having opposed front and rear ends, the front end being open, the rear end being attached to the upper portion of the housing, the rear end of the retaining member and the forward portion of the upper portion having an opening formed therein so that the forward end of the shaft and the front end of the needle selectively and slidably project therethrough and into an open interior region of the retaining member; and a bone implant having an outer shell and a medicament disposed in the outer shell, the bone implant being releasably disposed in the open interior region of the retaining member, the forward end of the shaft contacting the bone implant, whereby actuation of the trigger member causes the shaft and the needle to slide forward, the shaft pushing the bone implant out of the retaining member for deployment into a bone, the needle piercing the outer shell to release the medicament.
