Abstract

A semi-arc type corner of mouth retractor, comprising: an arc part that fits inside the oral cavity, and a handle that is integrally formed with the arc part and is easy to grasp. The handle is vertically connected to the outer wall of one end of the arc part. An arc surface is formed inside the arc portion, and the arc surface is completely attached to the soft tissue of the oral cavity. The utility model provides a semi-arc mouth angle retractor, which only needs to pull the upper or lower mouth angle of the patient when taking images of the occlusal surface of the dental arch of a patient with a small cleft in the outpatient treatment of the stomatology department. The lip and cheek tissues can expose the soft and hard tissues of the upper and lower jaws inside the oral cavity, which can be pulled more effectively, avoiding the influence of the retractor on the placement of the reflector and the effect of image shooting, and will not cause the patient to suffer from long-term treatment. more discomfort. The retractor has the advantages of small size, small coverage area, not easy to scratch the patient's lip and cheek tissue, simple operation, and high comfort for the patient.

Description

A kind of semi-arc type corner of mouth retractor

【Technical field】

The utility model relates to a pulling device, in particular to a semi-arc type puller for corners of the mouth.

【Background technique】

When shooting intraoral images in the outpatient department of stomatology, it is often necessary to pull the corners of the mouth or the upper and lower lips so that the soft and hard tissues to be treated can be fully exposed to the field of view, so as to capture standardized high-quality clinical digital images of the oral cavity. The existing retractors are large in size and cover too much tissue, which can easily crush the oral mucosa, which often causes discomfort to patients; when taking digital images of the occlusal surface of the dental arch, the existing retractors occupy a limited amount of space in the oral cavity. There is too much space, the patient's mouth opening is limited, and it is more difficult to insert the mirror, resulting in unsatisfactory image shooting.

【Content of utility model】

In order to solve the above problems, the utility model provides a semi-arc corner of the mouth retractor which is small in size, covers less tissue, and does not cause discomfort to the patient, so that it can quickly shoot images with good effects.

The utility model is realized through the following technical scheme, which provides a semi-arc-shaped corner of mouth retractor, comprising: an arc part that fits inside the oral cavity, and a handle that is integrally formed with the arc part and is easy to grasp. The handle is vertically connected to the outer wall of one end of the arc portion, and an arc surface is formed inside the arc portion, and the arc surface is completely attached to the soft tissue of the oral cavity.

In particular, the parts where the arc part is connected with the handle are respectively rounded.

In particular, the handle is provided with an anti-slip part.

In particular, the anti-slip part is at least five anti-slip strips wound around the outer wall of the handle.

In particular, both the arc portion and the outer wall of the handle are provided with frosted layers.

The utility model provides a semi-arc mouth angle retractor, which only needs to pull the upper or lower mouth angle of the patient when taking images of the occlusal surface of the dental arch of patients with small cleft mouth in the outpatient treatment of the stomatology department. Pulling the lip and cheek tissues can expose the soft and hard tissues of the upper and lower jaws in the oral cavity, which can be pulled more effectively and avoid the influence of the retractor on the placement of the mirror and the effect of image shooting, and it will not be damaged by long-term treatment. The patient has more discomfort. The retractor has the advantages of small size, small coverage area, not easy to scratch the patient's lip and cheek tissue, simple operation, and high comfort for the patient.

【Description of drawings】

Fig. 1 is a structural schematic diagram of a semi-arc type corner of mouth retractor of the present invention.

【Detailed ways】

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings.

Please refer to Fig. 1, the utility model provides a semi-arc-shaped corner of mouth retractor, including: an arc part 1 that fits inside the oral cavity, and a handle 2 that is integrally formed with the arc part 1 and is easy to grasp. The handle 2 is vertically connected to the outer wall of one end of the arc portion 1, and an arc surface 3 is formed on the inside of the arc portion 1, and the arc surface 3 is completely attached to the soft tissue of the oral cavity.

In particular, the parts where the arc portion 1 is connected to the handle 2 are respectively rounded; in this way, the corners of the mouth of the patient will not be uncomfortable during the stretching process, and the comfort of the patient is improved.

In particular, the handle 2 is provided with an anti-slip part; through the setting of the anti-slip part, the operator can better grasp the semi-arc-shaped corner of the mouth retractor during operation without slipping, thereby reducing the Patient discomfort caused by poor grip of the retractor by the operator.

In particular, the anti-slip part is at least five anti-slip strips 4 wrapped around the outer wall of the handle 2, and five anti-slip strips are used in this embodiment; the five anti-slip strips make it easy for the operator to grasp and will not be affected by Any discomfort in the hand caused by holding for a long time.

In particular, the outer wall of the arc portion 1 and the handle 2 are provided with a frosted layer, which can prevent the semi-arc-shaped corner of the mouth retractor from swaying randomly in the oral cavity, and can also improve the grip comfort of the operator. This indirectly improves patient comfort.

When in use, the operator holds the handle part, reminds the patient to open the mouth, rotates the arc part from one side of the mouth and inserts it into the patient's mouth, so that the arc surface fits the oral soft tissue completely, thereby pulling the patient's mouth corner function to facilitate follow-up work. When taking digital images of the occlusal surface of the maxillary dental arch, pull the soft tissue of the oral cavity with a little force upwards and outwards with the semicircular arc-shaped retractor; when taking digital images of the occlusal surface of the mandibular arch The oral corner retractor pulls the soft tissue of the oral cavity downwards and outwards, and then inserts the reflector, and instructs the patient to open the mouth as much as possible, and fully reflects the image of the occlusal surface of the upper and lower dental arches in the reflector , the photographer can shoot high-quality oral digital images through the mirror.
