Abstract
The utility model belongs to the technical field of medical instruments and particularly relates to an adjustable speculum for ear and nose examining. The adjustable speculum for ear and nose examining comprises two speculum bodies. The middles of the two speculum bodies are hinged through hinged shafts. One ends of the two speculum bodies are provided with handles oppositely and the other ends of the two speculum bodies are provided with speculum opening and closing heads oppositely. The two handles are provided with arc supporting rods and the hinged shafts serve as the centers of the two supporting rods. The top end of one supporting rod is provided with a sliding sleeve. A clamping sleeve which penetrates through the wall of the sliding sleeve is installed on the sliding sleeve. A compression spring is arranged between the clamping sleeve and the sliding sleeve. The inner surface of the part, abutting against the compression spring, of the clamping sleeve is provided with a first positioning bead. The other supporting rod penetrates through the clamping sleeve in a sliding mode and is provided with a second positioning bead. When the adjustable speculum is used, the clamping sleeve is pressed, the handles are held and the supporting rods penetrate through the sliding sleeve and the clamping sleeve in a sliding mode. When the proper distance is adjusted, the two supporting rods are fixed relatively, and the states of the handles and the speculum opening and closing heads are maintained. A doctor does not need to hold the handles all the time and the adjustable speculum is convenient to use and capable of facilitation an operation.

Technical field
This utility model belongs to medical instruments technical field, relates in particular to the adjustable specula of a kind of ear nose inspection.
Background technology
Auditory meatus or nasal cavity inspection are the main method that external auditory meatus or nose diseases are found and treated, the main utensil of nasal cavity inspection is nasal endoscope, and the main utensil of external auditory meatus inspection is endotoscpe, the body of existing nasal endoscope and endotoscpe is to be formed with axle is hinged by the specula expansion head of handle and handle front end, need to have other illuminator and frontal mirror to match when use.Concrete operation method is: the position of adjusting other illuminator and frontal mirror, reflect light into external auditory meatus or nasal cavity, asoscope or endotoscpe are put into patient's external auditory canal opening or nasal vestibule by examiner, open specula opening head, expand external auditory canal opening or prenaris, inspection external auditory meatus, tympanum and nasal septum, concha nasalis inferior, middle nasal concha, meatus nasi communis, inferior nasal meatus, middle nasal meatus and olfactory cleft etc. are located.
When existing nasal endoscope or endotoscpe use, need a continual gripping handle of hands with expansion nasal cavity or auditory meatus, doctor is easily tired, can only use a hands to carry out operation technique, while needing bimanualness more by force as operating difficulty, will pause, extend operating time.
Utility model content
The purpose of this utility model is to provide the inspection of a kind of ear nose adjustable specula, being intended to solve existing ear nose checks while use with nasal endoscope or endotoscpe, need continuous gripping handle of hands of doctor with expansion nasal cavity or external auditory meatus, easily tired, can only use a hands to carry out operation technique, extend the technical problem of operating time.
This utility model is to realize like this, the adjustable specula of a kind of ear nose inspection, comprise that two middle parts are by the hinged specula body of hinge, described in two, one end of specula body is provided with hands handle relatively, the other end is provided with specula opening head relatively, described in two, on handle, be equipped with the support bar of arc, described in two, support bar is all take described hinge as the center of circle, described in one, the top of support bar is provided with sliding sleeve, the cutting ferrule that runs through described sliding sleeve wall is installed on described sliding sleeve, between described cutting ferrule and sliding sleeve, be provided with Compress Spring, the inner surface of the part that described cutting ferrule and described Compress Spring offset is provided with the first location fin, described in another, support bar slides through described cutting ferrule and is provided with the second location fin corresponding with described the first location fin.
Improve as one, the cross section of described the first location fin and the second location fin is right angled triangle, and the hypotenuse of described the first location fin and the second location fin is oppositely arranged, the opposing setting of corresponding right-angle side.
Improve as another kind, described in two, between handle, be provided with the elastic component that struts described handle.
As improving further, the described support bar of slip is provided with scale.
Owing to adopting technique scheme, the beneficial effects of the utility model are:
Owing to being equipped with the support bar of arc on two handles, the top of one support bar is provided with sliding sleeve, the cutting ferrule that runs through sliding sleeve wall is installed on sliding sleeve, between cutting ferrule and sliding sleeve, be provided with Compress Spring, the inner surface of the part that cutting ferrule and Compress Spring offset is provided with the first location fin, another support bar slides through cutting ferrule and is provided with the second location fin corresponding with the first location fin, when use, press cutting ferrule, gripping handle, support bar slides through sliding sleeve and cutting ferrule, in the time being adjusted to suitable distance, unclamp cutting ferrule, two support bars are relatively fixing, keep the state of handle and specula opening head, do not need doctor with hands gripping handle always, easy to use.
Because the cross section of the first location fin and the second location fin is right angled triangle, the hypotenuse of the first location fin and the second location fin is oppositely arranged, the opposing setting of corresponding right-angle side, while making gripping handle, do not need to press cutting ferrule, while only having the original state of recovering handle, just need to press cutting ferrule, and between two handles, be provided with the elastic component that struts handle, make to use convenient.
Because the support bar sliding is provided with scale, facilitate doctor's regulating handle and specula opening head.
