The bioinjection device has a housing including a pistol grip and an elongated barrel. A trigger is pivotally mounted to the housing. A plunger and needle are slidable between a first position in which the plunger and needle are slidably disposed in the barrel and a second position in which the plunger and needle extend from an opening in the end of the barrel. A retaining member is disposed about the opening at the end of the barrel. A spring-biased actuation mechanism connects the trigger with the plunger and needle. A membranous cartridge containing bone morphogenic protein, antibiotics, and/or other medication is loaded into the retaining member. A surgeon can inject the cartridge into a bone fracture or degenerative bone tissue during surgery to deliver the medicament directly to the affected site.

We claim: 1. 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. 2. The bioinjection device as recited in claim 1, wherein said retaining member is releasably attached to the upper portion of said housing. 3. The bioinjection device as recited in claim 1, wherein the lower gripping portion of said housing is selectively rotatable with respect to the upper portion of said housing. 4. The bioinjection device as recited in claim 3, further comprising an upper handle mounted on said housing. 5. The bioinjection device as recited in claim 4, further comprising a side handle mounted on said housing. 6. The bioinjection device as recited in claim 1, wherein said bone implant has opposed forward and rear ends, the rear end being formed from a membranous material so that said needle pierces the membranous material to release the medicament. 7. The bioinjection device as recited in claim 6, wherein the forward end of said bone implant forms an engaging member and the rear end has a recess defined therein so that a plurality of said bone implants may be stacked together with the engaging member of one of said bone implants being received within a corresponding recess of an adjacent one of said bone implants. 8. A bioinjection device, comprising: a housing having an upper portion and a lower gripping portion, the upper portion of the housing having an open interior region defined therein; a shaft slidably disposed in the open interior region of the upper portion of the housing, the shaft having a channel formed therethrough, said shaft having opposed forward and rear ends; means for selectively driving 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; means for selectively driving 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 the opening into 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 retaining member, the forward end of the shaft contacting the bone implant, whereby selective forward translation of the shaft and the needle causes the shaft to push the bone implant out of the retaining member for deployment into a bone, the needle piercing the outer shell to release the medicament. 9. The bioinjection device as recited in claim 8, wherein the lower gripping portion of said housing includes a handle member and a trigger member, the trigger member being pivotally attached to the handle member. 10. The bioinjection device as recited in claim 9, wherein the lower gripping portion is pivotal with respect to the upper portion. 11. The bioinjection device as recited in claim 9, wherein said means for selectively driving sliding translation of said shaft with respect to the upper portion of said housing comprises 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 said shaft with respect to the upper portion of said housing. 12. The bioinjection device as recited in claim 11, wherein the rear end of said needle is 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 said needle with respect to the upper portion of the housing and the shaft. 13. The bioinjection device as recited in claim 12, wherein said retaining member is releasably attached to the upper portion of said housing. 14. The bioinjection device as recited in claim 8, further comprising an upper handle mounted on said housing. 15. The bioinjection device as recited in claim 14, further comprising a side handle mounted on said housing. 16. The bioinjection device as recited in claim 8, wherein said bone implant has opposed forward and rear ends, the rear end being formed from a membranous material so that said needle pierces the membranous material to release the medicament. 17. The bioinjection device as recited in claim 16, wherein the forward end of said bone implant forms an engaging member and the rear end has a recess defined therein so that a plurality of said bone implants may be stacked together, with the engaging member of one of said bone implants being received within a corresponding recess of an adjacent one of said bone implants.
