Abstract
A device for the treatment of periodontal disease includes a handle that has a configuration familiar to dental professionals, and a detachable tip or cartridge, that is locked into the handle when use. The device provides for automatically delivering a single dose of medicament, such as a powdered preparation of antibiotic, to a periodontal pocket for treatment of infection or disease.
Claims8
A periodontal medicament delivery device comprising:
- an actuator comprising a housing serving as a handle and having an open distal end in communication with
- a medicament delivery tip detachably affixed to the actuator, said medicament delivery tip having an elliptical outer circumference, while maintaining a circular axial bore longitudinally disposed through the medicament delivery tip, the circular axial bore of the medicament delivery tip containing a single dose of medicament and a medicament plunger, said medicament being contained at a distal end of said medicament delivery tip, and distal to said medicament plunger, wherein the distal end of the medicament delivery tip comprises a first angular cut and a second angular cut, the first angular cut and the second angular cut being diametrically opposed relative to the circular axial bore, said first and second angular cuts providing a two-pronged beveled wedge configuration at said distal end of the medicament delivery tip, and wherein each prong of said two-pronged beveled wedge configuration has a rounded distal end;
- wherein the actuator further comprises an internally disposed push rod coupled to a compression spring capable of storing energy when compressed, said push rod and said compression spring being lockable into a spring-loaded configuration by a catch upon compression of the compression spring;
- wherein release of the stored energy in the compressed compression spring is actuated by a single-action release operatively coupled to said catch, wherein actuation of the release is configured to be operated by a forefinger or other digit and not operated by pushing a plunger with a thumb, wherein said actuation results in automated movement of the push rod to engage the medicament plunger to deliver the medicament.
