Abstract
A dental mirror includes a handle having a lumen, a mirror housing attached to the handle, a mirror cartridge for insertion through a cartridge opening of the mirror housing, a drive shaft rotatably held within the handle, and a film-roller rotatably attached to a film-roller bearing. The mirror cartridge includes a base, a film-roller bearing connected to the base, a film support structure connected to the base, and a film surrounding the film support structure. A distal end of the drive shaft and a proximal end of the film-roller are rotatably linked such that a rotation of the drive shaft rotates the film-roller causing the film to move relative to the film support structure.
Claims34
A dental mirror comprising:
- a handle having a lumen extending from a handle distal end to a handle proximal end;
- a mirror housing attached to the handle proximal end;
- a mirror cartridge for insertion through a cartridge opening of the mirror housing, the mirror cartridge including a base, a film-roller bearing connected to the base, a film support structure connected to the base, a film surrounding the film support structure, and at least one elongated bearing member connected to the base and in contact with a film top surface;
- a drive shaft rotatably held within the handle;
- a film-roller rotatably attached to the film-roller bearing;
- and
- wherein a distal end of the drive shaft and a proximal end of the film-roller are rotatably linked such that a rotation of the drive shaft rotates the film-roller causing the film to move relative to the film support structure.
A mirror cartridge comprising:
- a base;
- a film-roller bearing connected to the base;
- a film support structure connected to the base;
- a film surrounding the film support structure;
- at least one elongated bearing member connected to the base and in contact with a film top surface:
- and
- wherein the cartridge is for insertion into a dental mirror.
A dental mirror comprising:
- a handle having a lumen extending from a handle distal end to a handle proximal end;
- a mirror housing attached to the handle proximal end;
- a mirror cartridge held within a cartridge opening of the mirror housing, the mirror cartridge including a base, a film-roller rotatably attached to the base, a film support structure connected to the base, a film surrounding the film support structure, and at least one elongated bearing member connected to the base and in contact with a film top surface;
- a drive shaft rotatably held within the handle;
- wherein a distal end of the drive shaft and a proximal end of the film-roller are rotatably linked such that a rotation of the drive shaft rotates the film-roller causing the film to move relative to the film support structure;
- an illumination source contained within the handle for illuminating an area in front of the mirror housing;
- and
- a motor contained within the handle and connected to a proximal end of the drive shaft.
