Abstract

The invention relates to medical technology, in particular to dental instruments. The purpose of the invention is to provide a dosed supply of a filling mass. The device includes a housing 1 with a curved fitting 6 fixed in its front part and a piston 2 placed inside the housing. The piston is made of three articulated links 9. In fitting 6, T-shaped protrusions 15 are formed laterally in contact with C-shaped slots. The drive through the links 9 moves the piston 2, providing a metered supply of filling mass into the dental canals. 19 il.

The invention relates to medical technology, in particular to dental instruments.

The purpose of the invention is to provide a dosed supply of a filling mass and to ensure quick-detachment of the nozzle.

Figures 1 and 2 depict the structure of the device in 2 projections in Fig. 3 — node I in Fig. 1; figure 4 - section aa on fig.Z; Figures 5 and 6 - fitting in 2 projections; figure 7 - node 11 in figure 5; in fig. 8 - the piston; 9 shows the piston head section, a slit; figure 10 - section bb in figure 2; in fig. 11 shows section B – E in FIG. one; in fig. 12 and 13 - C-image on the bracket in 2 projects; Fig. 14 shows the main part of the body, a section; in fig. 15 is a section of GGD in FIG. 1, and FIG. 16 is a section DD in FIG. one; in fig. 17 is a section view of EE in FIG. in fig. 18-section Ж-Ж in figure 1; in fig. 19 - section AND-And (fr ..

The device comprises a housing 1, a piston 2, a piston movement actuator 3, hinges 4 for stops 5, a fitting 6 with openings 7, a pusher in the form of three hinges 8 for connecting links 9, one of which has shaped grooves 10, recesses 11, additional hinges 12, handle 13, U-shaped single-pin lever 14, T-shaped projections 15, C-shaped grooves 16, glands 1 A device for sealing dental canals works as follows.

First, the internal cavity of the fitting 6 is filled with a filling mass in the required amount (approximately two dental cavities) and the fitting 6 is attached to the lever 14 so that the T-shaped projections 15 of the fitting 6 (see FIGS. 5 and 6) are located in the respective vertical grooves 16 (see Fig and 13), while the lever 14 is rotated all the way towards the front end of the housing 1.

While holding the fitting 6 with the thumb and pointing finger of the left hand, turn the lever 14 with the right hand as shown in FIGS. 1 and 10, while holding the body 1 with the right hand. When the lever 14 is rotated around the trunnions 17 formed on the housing 1 (see p. 11, 14 and 19), the G-grooves 16 slide onto the T-shaped projections 15

6 and will occupy the mutual position depicted on ftiHr.ll and 16.

Move the piston 2 in the direction of the fitting 6, for example, the muscular lever 14) see 1 and 2). Lever 14 is operated by the efforts of the human hand.

Install the end part of the fitting 6 into the base of the dental canal (cavity), as shown in Figs. 3 and 4, and pressurize the filling mass with the lever 14 (squeeze the fingers of the palm of the right hand) and remove them due to the efforts of the springs of the cheeks (release the fingers) while holding the device in the right hand. At the beginning of the filling of the dental canal, the filling mass, squeezing out from the tip (end part) of the choke, will force the existing air out of the cavity through the holes 7 (see fig. 3 and 4). This process continues until the dental cavity is completely filled, while in the process of squeezing the palm of the right hand, the device for filling rotates (shakes) at a small (about 10-15) angle, for example clockwise, and when the palm is unclamped in the opposite direction approximately the same angle is thereby removed from the filling mass of minute pip and - (small) air bubbles due to the presence at the end of the nozzle portion of the cross-shaped depressions (the protrusions on the end of the choke mix the filling mass and tamp).

Claims (2)
