Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1, an elastic dilator for oral clinical operation comprises a U-shaped support 1, an adjusting rod 3 and a supporting rod 5, wherein the U-shaped support 1 is an elastic support made of plastic material, oral cavity supports 2 are integrally arranged on two sides of an opening of the U-shaped support 1, threaded holes 8 are arranged at the joints of the U-shaped support 1 and the oral cavity supports 2, two ends of the supporting rod 5 are respectively provided with a first external thread 9 and a second external thread 10, and the first external thread 9 and the second external thread 10 are opposite in thread direction, the support rod 5 is installed in an opening of the U-shaped support 1 through the first external thread 9, the second external thread 10 and a threaded hole 8 in a threaded manner, the first bevel gear 6 is fixedly installed in the middle of the support rod 5, the adjusting rod 3 is movably inserted into the U-shaped support 1, the second bevel gear 7 is fixedly installed at the tail end of the adjusting rod 3, and the second bevel gear 7 is in meshing transmission connection with the first bevel gear 6.

The opening internal fixation of U type support 1 is equipped with the gag lever post 11 that is located the bracing piece 5 inboard, adjusts the end and the gag lever post 11 activity plug-in connection of pole 3, and gag lever post 11 is elastic support rod, carries on spacingly through gag lever post 11 to the end of adjusting lever 3, prevents its terminal skew, leads to No. two bevel gears 7 and bevel gear 6 to be connected not hard up.

The oral cavity supporter 2 is crescent, so that the oral cavity supporter more conforms to the internal shape of the oral cavity, and the oral cavity is conveniently opened.

The adjusting knob 4 is fixedly arranged at the top end of the adjusting rod 3, and the adjusting rod 3 is conveniently rotated through the adjusting knob 4.

Limiting baffles 12 are fixedly arranged at two ends of the supporting rod 5, the U-shaped support 1 can be limited, and the U-shaped support 1 is prevented from being separated from the end part of the supporting rod 5.

Specifically, when the device is used, the distance between the openings of the U-shaped support 1 is in a small state, so that the two oral cavity supporting bodies 2 can be conveniently placed into the oral cavity of a patient, medical staff can slowly rotate the adjusting rod 3 through the adjusting knob 4, the adjusting rod 3 drives the supporting rod 5 to rotate through the meshing transmission of the second bevel gear 7 and the first bevel gear 6, as the two ends of the supporting rod 5 are respectively in threaded connection with the two sides of the opening of the U-shaped support 1 through the first external thread 9 and the second external thread 10 in opposite directions, the rotation of the supporting rod 5 drives the two sides of the opening of the U-shaped support 1 to move outwards along the external threads of the supporting rod 5 through the screw rod transmission principle, so that the opening of the U-shaped support 1 is enlarged, the distance between the two oral cavity supporting bodies 2 is increased, the oral cavity of the patient is gradually opened until the feedback or operation check of the patient is needed, the oral cavity is opened, completing the supporting expansion of the oral cavity of the patient; in a similar way, after the operation or the examination is finished, the knob 4 can be rotated reversely, so that the opening of the U-shaped bracket 1 is contracted, the distance between the two oral cavity supporting bodies 2 is reduced, and the oral cavity supporting bodies 2 can be conveniently taken out from the oral cavity of the patient.
