Detailed Description

The utility model is further described below in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the utility model easy to understand.

Referring to fig. 1-3, an embodiment of the present utility model discloses an occlusal photographic retractor as a dental medical auxiliary apparatus, comprising an arcuate bar 10, wherein the arcuate bar 10 is used for supporting the inner side of an upper lip or the inner side of a lower lip and fitting with gums to open the lips so as to facilitate observation of the dental condition of a patient or photographing of oral teeth, two ends of the arcuate bar 10 are respectively connected with two support bars 20 obliquely downward, one end of the support bar 20a is inclined from top left to bottom right, and the other end of the support bar 20b is inclined from top right to bottom left; the length of the support pole 20 is about two centimeters. The device also comprises two lifting rods 30 which are respectively connected with the two support rods 20, wherein the other ends of the two lifting rods are free ends 30a, and the arrangement direction of the lifting rods 30 is opposite to the opening direction of the arched rod 10; the length of the lifting rod 30 is about 10 cm, and the left hand and the right hand can respectively hold the two lifting rods 30 to put the device into the oral cavity. In the embodiment of the utility model, the arched rod 10, the supporting rod 20 and the lifting rod 30 are integrally connected and are made of stainless steel. The arcuate bar 10 is circular in cross-section and has a diameter of 1-1.4 mm, typically 1.2 mm. The stainless steel bow-shaped rod with smaller diameter is placed in the oral cavity of a dental patient more comfortably, the device with smaller diameter has good elastic deformation performance, the free end 30a of the hand-held lifting rod is used for exerting forces in different directions of the lifting rod 30, the device can be pulled to further pull lips and cheeks to a certain extent, and doctors can observe the occlusal surface of the oral cavity of the patient and take pictures of the patient.

In the embodiment of the utility model, the whole occlusal photo drag hook device is centrosymmetric. The occlusal surface photo drag hook can support the inner side of the upper lip so as to observe the occlusal surface under the photographed teeth; and the lower lip can be horizontally turned over by 180 degrees, and the inner side of the lower lip is pressed down so as to observe the lower occlusal surface of the photographed teeth.

In addition, in the embodiment of the present utility model, the supporting rod 20 and the lifting rod 30 are vertically connected, and the two lifting rods 30 are in an splayed shape in space, so that a larger space is saved for the doctor to operate. The lifting rod 30 has a convex arc shape, has better elastic deformation performance,

according to the growth characteristics of teeth which incline slightly outwards from the inside of the oral cavity, the included angle formed by the tangent lines at the two ends of the arched rod 10 and the supporting rods 20 is designed to be an acute angle, so that the supporting rods can better fit the surfaces of the teeth, the comfort of patients in the oral cavity is improved, and the stability of the device in use is improved.

In addition, the free end 30a of the lifting rod of the embodiment of the utility model is internally coiled and formed with the finger pressing ring 31 towards the center line direction, and compared with a stainless steel round rod with 1.2 mm pinched by two fingers, the finger pressing ring 31 is more beneficial to pinching by two fingers so as to more conveniently operate and use the occlusal photographic drag hook.
