Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of pars oralis pharyngis operation visual field exposing device.
Background technology
At present, for the inspection of pars oralis pharyngis or when performing the operation, because the visual field not easily exposes, and nasopharynx part position is hidden, and due to pharyngeal reflection sensitive, the factors such as soft palate is long, clinical carry out indirect nasopharyngoscopy or operation time often cause the visual field not expose, cause failing to pinpoint a disease in diagnosis.At present, when carrying out nasopharynx part operation under looking at straight, usually adopt and catheter or dead point pipe are inserted from nasal cavity, draw from oral cavity through nasopharynx part, lie in front tooth front, nasopharynx part gap is increased, be convenient to expose art district.Its shortcoming causes upper lip and soft palate to strangle trace, and patient is uncomfortable, simultaneously can not effectively pull-up uvula, and visual area exposure is insufficient.
Summary of the invention
The purpose of this utility model is exactly the defect existed for prior art, provides a kind of structure simple, easy to use, can ensure that surgical field of view is clear, not lesion ports cavity tissue, be convenient to the pars oralis pharyngis operation visual field exposing device of surgical.
Its technical scheme is: pars oralis pharyngis operation visual field exposing device, comprise the upper tooth suitable with upper and lower teeth patterning to expand and to pad and lower tooth is expanded and padded, the both sides of described upper tooth expansion pad are rotatably connected to upper tooth expanding bar, the both sides of described lower tooth expansion pad are rotatably connected to lower tooth expanding bar, described upper tooth expanding bar and movable end corresponding to lower tooth expanding bar are rotationally connected, reset spreader spring is provided with between described upper tooth expanding bar and lower tooth expanding bar, the bottom of described upper tooth expansion pad is provided with clip, soft palate adjusting rod is movably equipped with in described clip, the end of described soft palate adjusting rod is provided with the drag hook that two centres have cavity.
Described soft palate adjusting rod is provided with fixed groove that is multiple and clip clamping.
Described drag hook outer surface is arranged with rubber sleeve.
Described lower tooth expansion pad is detachably provided with spatula.
This utility model compared with prior art, has the following advantages: structure is simple, and easy to use, can ensure that surgical field of view is clear, lesion ports cavity tissue, is not convenient to surgical.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Detailed description of the invention
With reference to Fig. 1, visual field exposing device is used in pars oralis pharyngis operation, comprise the upper tooth suitable with upper and lower teeth patterning and expand pad 1 and lower tooth expands pad 2, the both sides of described upper tooth expansion pad 1 are rotatably connected to upper tooth expanding bar 3, the both sides of described lower tooth expansion pad 2 are rotatably connected to lower tooth expanding bar 4, the movable end of described upper tooth expanding bar 3 and lower tooth expanding bar 4 correspondence is rotationally connected, reset spreader spring 5 is provided with between described upper tooth expanding bar 3 and lower tooth expanding bar 4, the bottom of described upper tooth expansion pad 1 is provided with clip 6, soft palate adjusting rod 7 is movably equipped with in described clip 6, the end of described soft palate adjusting rod 7 is provided with the drag hook 8 that two centres have cavity.
Described soft palate adjusting rod 7 is provided with fixed groove 9 that is multiple and clip 6 clamping.
Described drag hook 8 outer surface is arranged with rubber sleeve 10.Preventing from damaging when being fixed soft palate by rubber sleeve 10, alleviating patient suffering.
Described lower tooth expansion pad 2 is detachably provided with spatula 11.Can be fixed tongue by spatula 11, thus fully expose oropharynx position.
During use, upper tooth is expanded pad 1 and lower tooth expansion pad 2 put into intraoral upper tooth and lower tooth position, can automatically by oral cavity expansion by reset spreader spring 5, and supported by the upper tooth expanding bar 3 of both sides and lower tooth expanding bar 4, like this because upper tooth expanding bar 3 and lower tooth expanding bar 4 and reset spreader spring 5 are all positioned at both sides, oral cavity, do not block surgical field of view like this, surgical field of view can be made fully to expose, can be fixed tongue by spatula 11, better expose pharyngeal, then the appropriate location at soft palate rear is put into by drag hook 8 direct oral cavity, fully cruelly nasopharynx part can be leaked during pull-up soft palate, by the fixed groove 9 on soft palate adjusting rod 7, soft palate pull-up can be fixed it by fixed groove 9 and clip 6 after exposing nasopharynx part, inspection and the operation of nasopharynx part can be carried out like this.
