Title:
【発明の名称】硬質前端部を有する歯科治療用カートリッジ押し出し器
Document Type and Number:
Japanese Patent JPH09506271
Kind Code:
A
Abstract:
A manual dental extruder or syringe gun having a front end with rigid side walls and an opening therein adapted to receive a dental cartridge, capsule, ampule or tip having a flange. The body portion of the cartridge has a diameter less than that of the lateral width of the opening in the rigid side walls so that the dental cartridge can easily be dropped therein. At one end of the cartridge opening is a flange retainer. After dropping the dental cartridge in the front end, the cartridge is slid forward into the flange retainer. A portion of the rigid side walls extend over the flange when the dental cartridge is in position to be extruded. The rigid side walls improve the durability and strength of the dental extruder and prevents the dental cartridge from being pushed through the end of the extruder due to the large longitudinal forces required to extrude viscous dental materials.
