Description

[Detailed Description of the Invention] Technical Field The present invention relates to an improvement in a surgical light suitable for use in dental treatment and the like.

Prior Art In dental treatment, etc., surgical lights are used to illuminate the inside of the oral cavity during treatment, but if the surgical lights are not moved out of the way after use, it will be difficult for patients to enter and exit the treatment chair. or get in the way of
It was difficult to do the next task, but it was very troublesome and troublesome to put the surgical light back out of the way after each use.

Purpose The present invention was made in order to solve the above-mentioned drawbacks of the conventional technology.In particular, after use, the surgical light can be returned to a place out of the way by itself. The aim is to improve operability and work efficiency.

Configuration Figure 1 is an overall configuration diagram of the main parts showing an example of an operating light device to which the present invention is applied. In the figure, 10 is a fixed member attached to a fixed member or is rotatable in a plane perpendicular to the plane of the paper. 20 is a first joint, 30 is a second joint, 40 is a shaft rotatably connecting the first joint and the second joint, 50 is a vertical arm, 60 is a horizontal arm;
is a shadowless light section, and the shadowless light section 60 includes a shadowless light 61,
It consists of a handle 62 for attaching the surgical light 61, a switch 63 for turning on and off the surgical light 61, etc. After use, conventionally, after turning off the surgical light 61 with the switch 63, the handle 62 By holding the patient's hand, the surgical light section 60 is moved to a desired location, for example, a location where it does not interfere with the patient's access to and from the treatment chair. However, as described above, returning the surgical light to a place where it will not get in the way after each use is a very troublesome task, and is also a factor in reducing work efficiency.

The present invention was made in order to solve the above-mentioned drawbacks of the conventional technology. This is intended to improve operability and work efficiency by ensuring that the patient does not get in the way of getting in and out of the treatment chair or the subsequent treatment work.

FIG. 2 is an enlarged sectional view of the main part (part A in FIG. 1) for explaining one embodiment of the present invention.
~40 are the first relation 2 shown in FIG.
0, the second articulation 30, and the axis 40 correspond. 70 is an electromagnet, 71 is a nut, 72 is a spring, 73 and 74 are washers, and the spring 72 always applies an upward force to the joint 30.
However, during use, the electromagnet 70 is activated,
Thereby, the articulation 30 (and thus the vertically movable arm 50) can be stopped at any desired position. That is, the electromagnet 70 is connected to the surgical light section 60.
When in use, when the switch 63 is turned on, the surgical light 61 lights up, the electromagnet 70 is energized, and the upward force exerted by the spring 72 is braked.
Like a normal surgical light, the surgical light section can be moved to any desired location for use. After use, when the switch 63 is turned off, the surgical light 61 is turned off, the electromagnet 70 is deenergized, the joint 30 is lifted upward by the spring 72, and the surgical light 60 does not interfere with the patient's access. returned to position.

Effects As is clear from the above explanation, according to the present invention, after use, the surgical light unit automatically returns to the upper position where it does not interfere with the patient's access, etc., which improves operability and improves work efficiency. can be done.

Claims (1)

[Scope of utility model registration request] In a surgical light device that has a vertically movable arm extended via a joint part and a surgical light disposed at the tip of the vertically movable arm, and performs illumination by moving the surgical light. , a spring for displacing the vertically movable arm upward and an electromagnet are provided at the joint part, and when in use, the electromagnet is energized in synchronization with lighting of a surgical light to cause the arm to move upwardly. and when the surgical light is not in use, the electromagnet is deenergized in synchronization with the extinguishing of the surgical light, and the vertically movable arm is returned to an upper position by the force of the spring. Self-returning device.
