BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental instrument holder, and more particularly to posture control thereof.
[0002]
2. Description of the Related Art Conventionally, in a dental chair unit, the attitude control of an instrument holder integrated with a bracket table is performed by three methods of fixed or swiveling to the left and right and angular inclination with respect to the upper bracket table. The axis was moving.
[0003]
In order to place an instrument on an instrument holder, it is roughly classified into horizontal (horizontal), vertical (vertical), and diagonal placement. However, the range of the attitude control of the instrument holder itself during the treatment is limited and the degree of freedom is low.
The present invention provides an instrument holder in which a total of five axes are moved by adding a two-axis swivel movement up and down to the three-axis movement, thereby increasing the degree of freedom in posture control.
[0004]
In view of the above, the present inventors have solved the above problems by the following means as a result of experimental research.
(1) In an instrument holder integrated with a bracket table of a dental chair unit,
A first horizontal rotation axis of the instrument holder fixedly provided in front of the lower surface of the upper bracket table, and a first vertical rotation axis disposed below the first horizontal rotation axis;
A second horizontal rotation axis attached to the lower back of the instrument holder and a second vertical rotation axis disposed above the second rotation axis;
An instrument holder is provided by a total of four joints, two horizontal axes and two vertical axes, which are supported by an arm between the first vertical rotation axis and the second vertical rotation axis. The dental instrument holder is characterized in that the bracket table can be moved left and right and moved up and down with respect to the bracket table.
(2) In an instrument holder integrated with a bracket table of a dental chair unit,
A first horizontal rotation axis of the instrument holder fixedly provided in front of the lower surface of the upper bracket table, and a first vertical rotation axis disposed below the first horizontal rotation axis;
A second horizontal rotation axis attached to the lower back of the instrument holder and a second vertical rotation axis disposed above the second rotation axis;
The first vertical rotation axis and the second vertical rotation axis are pivoted by an arm,
Further, the second horizontal rotation shaft of the instrument holder and the second vertical rotation shaft disposed above the second rotation shaft are connected to a tilt angle adjusting mechanism for adjusting the front and rear tilt angles of the instrument holder. Being
The instrument holder moves left and right, moves up and down, and tilts back and forth with respect to the bracket table by a total of 5 joints: 2 horizontal axes, 2 vertical axes, and 1 tilt axis. A dental instrument holder, characterized in that it can be used.

[0007]
FIG. 3 is an external view of FIG. 1 as seen from the front. The instrument holder 2 is moved directly below the pivot arm 17, and the bracket table 1 and the instrument holder 2 are vertically moved. The relational position is farthest away.
In this state, since the instrument holder 2 is located below, the instrument 3 can be easily taken out, and the instrument holder 2 is tilted back and forth (described later) so that the instrument 3 can be placed in the horizontal direction. Since it can be set to any of the vertical, vertical, and diagonal positions, it is possible to select an optimal position for medical treatment.
FIG. 4 is also an external view of FIG. 1 as viewed from the front, but the instrument holder 2 is moved to the leftmost side (not shown) via the pivot arm 17, and the bracket table 1 The left and right relative positions of the instrument holder 2 are the same.
In this state, the space factor is the best.
The placement position of the instrument 3 is the same as in FIG. 3 in the case of FIGS. As described above, the degree of freedom of posture control of the instrument holder 2 is high, and the practitioner can easily select the optimum position.
[0008]
Next, the operation will be described with reference to the external perspective view of the 5-axis joint arm at the lower back of the instrument holder, the mechanism diagram of FIG. 5 and the 5-axis joint arm, and FIG.
Assume that the bracket table mounting portion 22 on the upper surface of the mounting table 14 of the bracket table has the bracket table 1 as shown in FIG. 1 (not shown). A shaft arm 17 is attached to the vertical and horizontal axis rotating parts 21 via a first horizontal rotating shaft 15 and a first vertical rotating shaft 16 below the mounting table 14 of the bracket table. It is worn.
The vertical and horizontal axis rotating portions 21 have a second vertical rotating shaft 18 and a second horizontal rotating shaft 19 and are connected to an inclined mounting mechanism 26 having an inclined rotating shaft 27 and an inclination angle determining screw 28. ing.
Therefore, the mechanism of the five-axis joint arm unit described above includes the first horizontal rotation shaft 15 and the first vertical rotation shaft 16, and the second vertical rotation shaft 18 and the second horizontal rotation shaft 19. Since there are a total of five rotating parts including a four-axis rotating part and an inclined rotating axis 27, the left and right, upper and lower positions of the instrument holder 2 and the front and rear inclination angles can be freely set. Can do.
In order to set, for example, when the left and right ends of the instrument holder 2 are grasped and moved to a predetermined position, the joint portion is adjusted so as to be locked at the stop position (not shown). .
