Technical field

The utility model relates to a kind of arc retractor.

Background technology

As everyone knows, oral cavity doctor clinically, in the time carrying out examination of mouth for patient, adopts spatula to press expanded support oral cavity mostly, and operation extremely bothers, wastes time and energy and be fixing insecure like this, has increased great work difficulty to doctor. What have also uses retractor, and the retractor adopting is " U " shape, and two ends of retractor are connected with respectively the sheet of dehiscing. Retractor body has elasticity, in use, whole retractor is placed on lip outside, two sheets of dehiscing of retractor are for strutting the left and right sides of lip, what opened in oral cavity on the one hand is large not, and inconvenient doctor observes treatment, on the other hand in use, patient's tongue meeting voluntary activity, affects doctor's observation and treatment.

Utility model content

The arc retractor that provides a kind of doctor of convenience to observe and treat for the deficiency of above-mentioned prior art existence is provided technical problem to be solved in the utility model.

The technical scheme that the utility model adopts is: a kind of arc retractor, comprise retractor body, it is characterized in that described retractor body is arc, two ends in retractor body are connected with respectively the sheet of dehiscing, be used for being supported on lip both sides, described retractor body has elasticity, two back of a bow of retractor body can be to bending in the inside of retractor body or outside in the time of the compressing being subject to by ambient pressure, in the time that external pressure disappears, two back of a bow of retractor body return to original position again, in use, the back of a bow of described retractor body is arranged on inside, patient oral cavity.

By technique scheme, be provided with vertical gear tongue piece at the middle part of retractor body, for suppressing tongue activity.

By technique scheme, described gear tongue piece is arranged on the both sides, middle part of retractor body, two parts that are divided into that one is long and the other is short.

By technique scheme, described in the dehisce inner side of sheet be concave circular arcs shape.

By technique scheme, described in the sheet of dehiscing be the telescopic sheet of dehiscing, its flexible track is circular-arc, to adapt to different crowd.

By technique scheme, described retractor body length is 8cm-16cm, the wide 0.4cm-0.8cm of retractor body, described gear tongue block length 1.5cm-3cm, described in the wide 0.8cm-1.6cm inside sheet that dehisces.

The obtained beneficial effect of the utility model is: the utility model used apparatus that struts oral cavity during for correction or department of stomatology patient treatment, in use, the back of a bow of the present utility model is arranged in patient's oral cavity, reduce the treatment obstacle while using the utility model, dentist being formed, by using the utility model, patient's oral cavity is opened as far as possible, expose, facilitate dentist to observe and treat; The utility model is simple in structure, easy and simple to handle, and with low cost, is applicable to various oral medicals institutes and uses; Arc by retractor body is arranged to, be for allowing the utility model voluntarily to opening and the application of force, allowing retractor that patient's oral cavity is pulled open; The sheet of dehiscing of two ends of retractor oppositely arranges arcs of recesses, is that retractor can not be come off in patient oral cavity on the one hand, makes on the other hand patient there is no sense of discomfort; Vertical direction block is set on the middle part of retractor body, for suppressing tongue activity, is convenient to dentist and observes and treat.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As Figure 1-4, the present embodiment provides a kind of arc retractor, comprises retractor body 1, and described retractor body 1 is arc, be connected with respectively one in two ends of retractor body 1 and dehisce 3, described in the dehisce inner side of sheet 3 be concave circular arcs shape. Described retractor body 1 has elasticity, two back of a bow 2 of retractor body can be to bending in the inside of retractor body 1 or outside in the time of the compressing being subject to by ambient pressure, in the time that external pressure disappears, two back of a bow of retractor body 1 return to original position again, in use, the back of a bow 2 of described retractor body 1 is arranged on inside, patient oral cavity.

By technique scheme, be provided with vertical gear tongue piece 4 at the middle part of retractor body 1, for suppressing tongue activity, described gear tongue piece 4 is arranged on the both sides, middle part of retractor body 1, two parts that are divided into that one is long and the other is short.

In the present embodiment, described in dehisce sheet 3 for the telescopic sheet of dehiscing, its flexible track is circular-arc, to adapt to different crowd.

In the present embodiment, described retractor body 1 length is 8cm-16cm, the wide 0.4cm-0.8cm of retractor body 1, described gear tongue block length 1.5cm-3cm, described in the sheet 3 wide 0.8cm-1.6cm in inner side that dehisce.

In use, the back of a bow of described retractor body is arranged on inside, patient oral cavity, left side and the right side in two sheet oral cavities of dehiscing, because retractor body has elasticity, two back of a bow of retractor body are to the interior curve of retractor body in the time of the compressing being subject to by ambient pressure, and in the time that external pressure disappears, two back of a bow of retractor body return to original position again, thereby strut patient's oral cavity, facilitate dentist to observe and treat.
