MEDICAL TREATMENT APPARATUS AND NEEDLE MANUFACTURING METHOD

摘要

An apparatus (200) for dispensing material (70) during a dental or endodontic procedure includes a housing (220) having a motor (242) with an output. A needle heating member (252) including a chamber may receive a prefilled needle (16) of dispensing material (70). A heater (250) at least substantially surrounds the chamber for heating the material (70) in the needle (16). A plunger (246) is used to expel the material from the needle (16) during activation of the motor. A reusable protective sheath (100) is provided for disposition on the outside of the housing (220). A method of manufacturing a needle (16) for use and dispensing a material (70) during a dental or endodontic procedure includes drawing a blank of metal having a closed distal end, bending the blank at a desired angle, and removing a portion of the drawn metal from the distal end to open the distal end thereby forming the dispensing needle (16).
