Description

[Detailed Description of the Invention] The present invention relates to an improvement of a surgical chair.

In general, in an operating room, various instruments are placed between the operating table and the operator's chair, so it has been impossible to move the chair closer to the operating table.

In view of the above-mentioned problems, the present invention aims to provide a surgical chair in which only the seat can be moved closer to the operating table without changing the position of the legs, and in conjunction with this, the footrest can be moved backward. However, this will be explained based on an example illustrated below.
1 is a leg with casters 2 attached to the bottom, 3
4 is a lower pedestal fixed to the upper end of the leg portion 1, and 4 is mounted on the lower pedestal 3 so as to be able to slide in the horizontal direction, and is fixed to the lower pedestal 3 at a desired position by means of a fixing knob 5. upper pedestal adapted to obtain, 6
8 is a backrest fixed to the upper pedestal 4, 7 is a seat fixed to the upper pedestal 4, and 8 is a vertically long seat whose upper end is pivotally connected to the tip of the upper pedestal 4 via a rotating shaft 9 and approximately in the center. A movable arm 10 is formed with a hole 8a, a recess 8b and a pin hole 8c at its lower end, and the rear end is fixed to the lower pedestal 3 by a fixing screw 11.
A fixed arm 13 has a shaft 12 fixed to its rear end and fixed to its tip and slidably fitted into a long hole 8a of the movable arm 8; a slide arm 15 positioned and fixed by a pin 14
A footrest 17 is pivotally connected to the lower end of the slide arm 13 via a rotating shaft 16, and a footrest 17 is screwed to the rear upright portion of the footrest 15 so that it can move forward and backward, and its tip abuts against the slide arm 13. footrest 1
This is an angle adjustment screw that adjusts the inclination of 5.

Since the operator's chair according to the present invention is constructed as described above, for example, when the upper pedestal 4 is moved forward (to the left in FIG. 2) with respect to the lower pedestal 3 in the state shown in FIG. The movable arm 8 rotates to the left around the rotating shaft 9 while being restricted by the fixed arm 10, and as a result, the footrest 15 moves rearward and upward relative to the upper base 4 as shown in FIG.
Therefore, if the seat is fixed as it is, only the seat 7 will be brought closer to the operating table, etc., and the footrest 15 will be moved back, without changing the position of the legs 1. Next, the height of the footrest 15 is adjusted by moving the slide arm 13 in the longitudinal direction of the movable arm 8 and positioning and fixing it at a desired position using the pin 14. Furthermore,
By moving the angle adjustment screw 17 forward and backward to adjust the angle of the footrest 15 with respect to the movable arm 8, the operator can perform surgery while leaning on the chair in a comfortable posture according to the usage condition. Furthermore, since the present surgeon's chair allows the distance between the footrest 15 and the seat 7 to be adjusted, the operator can perform surgery while leaning on the chair in a comfortable posture that matches the length of his or her legs. Furthermore, the angle of the footrest 15 can be set to suit the operator's preference, which is convenient. or,
Since various switches can be incorporated into the footrest 15, it is suitable for microsurgery.
Further, since the footrest 15 is adapted to move up and down in conjunction with the seat 7, there is an advantage that the surgical posture does not need to be changed even if the seat 7 is moved up and down electrically or manually.

As described above, the operator's chair according to the present invention is convenient because the seat can be moved closer to the operating table and the footrest can be moved back without changing the position of the legs.
In addition, the present surgical chair allows the height and angle of the footrest to be adjusted, allowing the surgeon to perform the surgery in a comfortable position.
