Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instrument holder for dental treatment for holding a treatment tool such as a handpiece used in a dental clinic or the like.

[0002]

2. Description of the Related Art In treatment at a dental clinic, a dentist freely moves a dental table on which dental treatment tools, chemicals and the like are placed, and treats a patient. An instrument holder for holding a dental treatment tool such as a handpiece connected to the tip of a movable hose is provided on the lower front surface of the table.

[0003] The instrument holder stably holds the treatment tool and the like, and can be moved to an appropriate position when performing treatment on a patient. A conventional instrument holder for dental treatment is fixed to a lower front surface of the dental table with a bracket or the like, or is provided so as to be rotatable left and right with respect to the dental table.

A holder for holding a treatment tool or the like is provided at the tip of the bracket. The holder is provided to be rotatable up and down with respect to the bracket, and the angle of the holder is adjusted to use the treatment tool or the like. ing.

Therefore, when performing treatment on a patient, the dental table is moved to a position desired by the dentist,
The holder for holding the dental treatment tool is used at a position and an angle that are easy to take out.

[0006]

However, the conventional instrument holder for dental treatment is provided on the lower front surface of the dental table and can move in the left-right direction.
There is a problem that the height and the interval between the dental table and the instrument holder are constant, and the height of the instrument holder is determined by the height of the dental table. For this reason, there is a problem that the dentist cannot set the instrument holder at a height that is easy to use when giving a treatment to the patient.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide an instrument holder provided on a lower surface of a dental table, regardless of the height of the dental table. It is an object of the present invention to provide an instrument holder for dental treatment which can be freely moved to an angle and an angular position and can be used freely.

[0008]

SUMMARY OF THE INVENTION An instrument holder for dental treatment according to the present invention achieves the above-mentioned object, and is provided on a lower front surface of a dental table, and is provided with respect to a floor surface. A first rotatably provided in the horizontal direction
An arm, a second arm provided at the end of the first arm so as to be rotatable in the vertical direction with respect to the floor surface, and a handpiece provided at the end of the second arm so as to be rotatable in the up and down direction. And a holder for holding a dental treatment tool.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of an instrument holder for dental treatment according to the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic view showing a state in which an instrument holder for dental treatment is attached to a dental table, and FIG. 2 is a partial cross-sectional side view showing a state in which the instrument holder for dental treatment is attached to a dental table. FIG. 3 is a plan partial sectional view of the instrument holder for dental treatment.

Reference numeral 1 denotes a dental table on which instruments, chemicals, and the like are placed. The treatment table 1 is fixed to a bracket 2, and the bracket 2 is rotatably provided on a base arm 3. 1a is a handle for moving the dental table 1.

Reference numeral 4 denotes a rotating shaft fixed to the lower front surface of the dental table 1 with screws or the like. Reference numeral 5 denotes a first arm, which is fitted on the rotation shaft 4 and is provided so as to rotate left and right. (The rotation axis A shown in FIG. 1 is formed.) The first arm 5 is held on the rotation shaft 4 by a stop ring 6.

Reference numeral 7 denotes a second arm, which has a shaft hole 7a. Reference numeral 8 denotes a rotating shaft pin, which is fitted in the shaft hole 7a. Therefore, the second arm 7 is rotatably supported on the first arm 5 in a vertical direction. (Formation of the rotation axis C shown in FIG. 1) By tightening the screw 9, the diameter of the shaft hole 7a of the second arm 7 can be made small, and the rotational friction with the rotation axis pin 8 can be adjusted. It is provided as follows.

Reference numeral 10 denotes a holder for holding a dental treatment tool such as a handpiece. Also, a hook 10b is provided. A rotating shaft pin 10a fixed to the holder 10 is fitted in a shaft hole 7b provided at a distal end portion of the second arm 7, and is provided so as to be vertically rotatable with respect to the second arm 7. I have.

Further, by tightening the screw 11, the second
The diameter of the shaft hole 7b of the arm 7 can be made small, and the shaft hole 7b is provided so that the rotational friction with the rotational shaft pin 10a can be adjusted. 12 is a cover for covering the second arm 7,
It is fixed to the second arm 7 with screws or the like.

As shown in FIG. 1, the first arm 5 holds the holder 10 with respect to the dental table by the rotation axis A provided on the lower front surface of the dental table 1 as shown in FIG. It can rotate left and right. Further, since the second arm 7 can be turned up and down with respect to the first arm 5 by the turning shaft B, the holder can be turned up and down.

Further, since the holder 10 can be rotated by the rotation axis C, it is possible to maintain a dental treatment tool such as a handpiece hooked on the holder 10 at an easy-to-take angle. Accordingly, if the dentist moves the dental table to an appropriate position with respect to the patient, the dentist can freely and finely move the holder 10 to a desired position thereafter, and can use the holder 10 easily. Further, since the second arm 7 and the holder 10 can adjust the rotational friction, respectively, the holder 10 can be fixed.

[0018]

According to the present invention, as described above, the holder on which the dental treatment tool such as a handpiece is hung can be easily moved right and left and up and down with respect to the dental table. When the dentist moves the dental table to an appropriate position, the dentist can easily adjust the position of the holder.

Also, since the angle of the holder can be adjusted, the dentist can use a treatment tool such as a handpiece that is hung on the holder 10 at a position and an angle where it can be easily taken out during treatment. Can provide optimal treatment.
