Description

Ear hanging type mouth and corner tractor

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a hangers formula lip tractor.

Background

In the oral clinical treatment process, the reasons that the treatment difficulty of the upper jaw second molar, the third molar and the like in the mouth is large and close to pharyngeal tissues come from the unclear deep visual field of the oral cavity and the small operation space, and for the situations, doctors mostly rely on the instruments to draw the soft tissues on the buccal side, and the treatment operation is carried out in the modes of intermittent operation, application of an oral mirror, change of the body position and the like, so that the treatment is complex and tedious.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a hangers formula lip tractor to the not enough of prior art.

The purpose of the utility model is realized through the following technical scheme: a suspension loop type oral angle tractor comprises an ear hook, an ear fixer, an elastic band, a nested connecting device, a U-shaped oral angle drag hook, a drag hook sleeve head, an L-shaped stainless steel sheet, a mirror and a rotatable fixing head;

the ear hook is attached to the auricle and is attached to the tragus through the ear fixer; one end of the elastic band is fixedly connected with the ear fixing device, and the other end of the elastic band is connected with one end of the U-shaped corner drag hook through the nested connecting device;

the U-shaped mouth corner retractor crosses the mouth corner from the buccal mucosa to the outer cheek in an arc shape; the other end of the U-shaped corner opening draw hook is connected with an L-shaped stainless steel sheet with a telescopic structure in a nesting mode through a draw hook sleeve head; the L-shaped stainless steel sheet is provided with a mirror.

Further, the mirror is trapezoidal and is installed on the L-shaped stainless steel sheet through the rotatable fixing head.

Further, the telescopic range of the L-shaped stainless steel sheet with the telescopic structure is adapted to the depth in the mouth of the patient.

Furthermore, the U-shaped corner drag hook extends out to be protruded to be connected with the nested connecting device in the direction vertical to the elastic band, and the double ends of the elastic band are reversely folded into a ring shape and connected with the nested connecting device.

The utility model has the advantages that: the utility model discloses can utilize the stable tractive oral angle of external force volume backward, fixed oral lip exposes the operation field of vision smoothly, increases operation space, makes the doctor can see the far from the central plane of art district such as second molar, third molar smoothly through the device mirror surface is clear, reduces to diagnose the degree of difficulty, shortens to diagnose long.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a suspension loop type oral angle retractor, which comprises an ear hook 1, an ear fixer 2, an elastic band 3, a nested connecting device 4, a U-shaped oral angle retractor 5, a retractor sleeve head 6, an L-shaped stainless steel sheet 7, a mirror 8 and a rotatable fixing head 9;

in the intraoral part, an L-shaped stainless steel sheet 7 is connected with a U-shaped oral angle draw hook 5 in a nesting mode through a draw hook sleeve head 6, the L-shaped stainless steel sheet 7 can be stretched and retracted and can be adjusted according to different intraoral depths of patients, a trapezoidal mirror 8 is connected with the L-shaped stainless steel sheet 7 through a rotatable fixing head 9, and finally the far middle surface of a molar tooth is observed smoothly;

in the connecting part, the U-shaped lip angle drag hook 5 passes over the lip angle from the oral buccal mucosa to the external cheek in an arc shape, so that the skin of the lip and cheek of a patient is protected, and the phenomena of lip angle inflammation and lip angle ulceration caused by over-traction are avoided;

in the external portion of mouth, U type mouth angle drag hook 5 stretches out the protruding nested formula connecting device 4 of connecting to 3 directions of perpendicular elastic band, and 3 double-end inflections of elastic band are the circle form, link to each other with nested formula connecting device 4, and the auricle is laminated to earhook 1 and laminates in the tragus with the help of ear fixer 2, provides stable strength that lasts for opening of mouth angle, need not doctor, assistant's application apparatus and opens the mouth angle, the doctor's both hands operation of being convenient for.

The utility model discloses the use step:

(1) the U-shaped mouth corner drag hook 5 is fixed at the mouth corner;

(2) the L-shaped stainless steel sheet 7 at the inner part of the mouth extends out of the sleeve head for a length;

(3) the ear hook 1 is sleeved on the auricle to stabilize the tractor;

(4) the positions of the L-shaped stainless steel sheet 7 and the mirror 8 in the mouth are finely adjusted to the position where the far middle surface of the operation area can be observed.

The above-mentioned embodiments are provided for explaining the present invention, not for limiting the present invention, and any modifications and changes made to the present invention are within the spirit of the present invention and the scope of the claims and fall within the scope of the present invention.
