BIOINJECTION DEVICE

摘要

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.

主权项

1. A bioinjection device for delivering medicament into bone tissue, comprising:
a housing having a grip and an elongated barrel extending away from the grip, the barrel having a bore; a trigger pivotally mounted on the housing; a plunger having a pointed end, the plunger movable between a first position in which the pointed end is retracted within the bore of the elongated barrel and a second position in which the pointed end extends beyond the bore; a retaining member disposed about an opening of the bore, the retaining member receiving a cartridge containing a medicament; and a spring-biased actuation mechanism coupling the trigger with the plunger, wherein the plunger moves from the first position to the second position when the trigger is actuated.
