Example one

The appliance is a medical appliance for correcting teeth, and the appliance is opened by placing an appliance spiral spring at a proper position in the oral cavity, using an appliance key, and transmitting the correcting force to teeth and alveolar bones so as to enlarge the width and length of the upper and lower jaw dental arches and achieve the effect of orderly arranging the teeth.

At present, the bow expander is opened and closed by adjusting a key of the bow expander, and the bow expander key is inserted into an adjusting hole and then rotates, so that the supporting rod is pushed towards two sides, and the bow expanding effect is achieved. However, when the opening and closing of the arch expander are adjusted, because the oral cavity is dark, a person is usually required to assist the orthopedic physician to illuminate with a lighting device such as a flashlight to observe the conditions in the oral cavity, which causes inconvenience in operation and affects the orthopedic efficiency.

In view of this, the embodiment of the present invention provides an expander key and an expander, please refer to fig. 1, the expander key includes: a handle 100 and a key head 200; the handle 100 and the key head 200 are rotatably connected by a rotary member 300; the rotating member 300 is connected with a light source 400, and the light source 400 is configured to emit light when the key head 200 is inserted into the adjustment hole of the pantograph expander.

The embodiment of the utility model provides a following beneficial effect has been brought:

when inserting the key head 200 of expanding the bow ware key into the regulation hole of expanding the bow ware, the light source 400 of being connected with rotating member 300 can give out light, is convenient for correct doctor and observes the condition in the oral cavity in order to expand bow ware reasonable regulation, no longer need other people to carry out auxiliary lighting, and is easy and simple to handle, has improved greatly and has corrected efficiency.

The connection between the rotating member 300 and the light source 400 is specifically described as follows:

referring to fig. 2, a groove 310 is formed on a surface of the rotating member 300, and the light source 400 is fixedly installed in the groove 310.

The light source 400 is fixedly mounted in the groove 310 on the surface of the rotating member 300, so that the overall volume of the bow expander key is kept approximately the same, and the bow expander key is convenient to carry and use.

Further, a lamp housing 410 is provided outside the light source 400, and the lamp housing 410 is coupled to the rotary member 300 by a coupling structure.

Specifically, the connection structure includes protrusions at both ends of the lamp housing 410 and connection grooves on the surface of the rotary member 300, and the protrusions protrude into the connection grooves such that the lamp housing 410 is connected to the rotary member 300.

Of course, the connection structure is not limited to the above structure, and the lamp housing 410 may be connected to the rotary member 300 by means of a bolt connection or a snap connection.

The lamp housing 410 can provide effective protection for the light source 400, so that the light source 400 is stably mounted in the groove 310 on the surface of the rotating member 300.

Further, a sealing strip 420 is attached to the outer surface of the lamp housing 410.

The sealing strip 420 can prevent liquid such as saliva in the oral cavity from flowing into the lamp shade 410 and further influencing the light emitting effect of the light source 400 when the bow expander key is used, so that the bow expander key can be always normally used.

In an alternative to this embodiment, it is preferable that,

the surface of the handle 100 is provided with a battery slot, and a battery is placed in the battery slot to supply power to the light source 400.
