Abstract
The invention provides a throat dilator. The structure of the dilator is composed of a handle, a fixed opening plate, a movable opening plate, a trigger, an accumulator and a light emitting diode ratchet mechanism; the fixed opening plate is in a circular arc shape and is arranged at the top part of the handle, the arc circular shaped movable opening plate is arranged at the lower part of the fixed opening plate, the front part of the movable opening plate and the front part of the fixed opening plate are corresponding and in a duckbill shape, a viewing hole is arranged between the handle and the fixed opening plate, and the trigger arranged at the lower end of the movable opening plate is arranged at the lower part of the viewing hole through a hinge axis. Compared with the prior art, the dilator has the advantages that the structure is simple, the operation is convenient, the pain of the patient is less, the dilator is provided with a power source and a lighting fixture, the visual angle is good, and the dilator is convenient for the operation, and the dilator has good popularization value and application value.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically a kind of throat's dilator that throat diseases is observed and treated.
Background technology
Current throat check and operation in using three kinds of apparatuses and method promptly: (one) laryngeal mirror, (2) direct laryngoscope, (3) supporting laryngoscope, use laryngeal mirror need use the frontal mirror reflect lighting, left hand thumb and middle finger pull tab, forefinger props up patient's upper tooth and fixes, the right hand hold laryngeal mirror heat put into behind the minute surface pharyngeal, utilize its reflection frontal mirror illumination to check each one of laryngopharynx, when performing the operation, larynx then needs the own pull tab of patient because of operation technique, doctor's left hand is held laryngoscope, right hand one-handed performance, check or operation in since light source a little less than, the doctor, it is not good to suffer from cooperation, patient's back arch is can not fine exposure pharyngeal, or pharyngeal reflex allergy when causing holding one's breath vomiting laryngoscope be difficult to put into, can because of can not on lift the inlet of covering larynx and make and check failure or perform the operation and be difficult to carry out; Use direct laryngoscope, need the patient to lie on the back, head and neck places outside the operating-table, and oral cavity and cavum laryngis are in a straight line, and doctor's left hand is held the direct laryngoscope lens barrel and imported pharyngeal along back center or right side, check and perform the operation by lens barrel, but the importing of thick direct laryngoscope lens barrel is easy to cause nausea, vomit, and damage larynx, pharyngeal mucous membrane are relatively more painful, need table fiber crops or general anesthesia, operating time is long, greatly dangerous and the machine price is more expensive; Supporting laryngoscope with machinery replace staff fixedly laryngoscope be convenient to carry out micro-complicated operation, respectively there is a fibre light guide wick cold light source lens barrel tube wall both sides, well lighted, being equipped with microscope improves the operation degree of accuracy, but complicated operation, time length, patient are also relatively more painful, microsurgery must carry out in general anesthesia, has increased danger and throat's mucosal injury in the art, and the patient is difficult for accepting.Use laryngeal mirror to carry out the report of operation on vocal cord though have abroad, so far still do not see simple in structure, easy to use, and patient's throat's expansion apparatus of taking like a shot.
Summary of the invention
The purpose of this invention is to provide a kind of throat dilator.
The objective of the invention is to realize in the following manner, this kind throat dilator is by handle, fixing distraction plate, movable distraction plate, trigger, accumulator, light emitting diode and ratch mechanism are formed, fixedly distraction plate is the top that circular arc is arranged on handle, circular arc activity distraction plate is arranged on the fixedly below of distraction plate, the front portion of movable distraction plate and the fixing anterior corresponding duckbill that is of distraction plate, handle and fixedly be provided with observation port between the distraction plate, the lower end of movable distraction plate is connected with trigger and is arranged on the below of observation port by hinge axis, and ratch mechanism is arranged between handle and the trigger.
The beneficial effect that dilator of the present invention has is, and is simple in structure, easy to use, little, the self-powered and lighting of patient suffering, and observation visual angle is good and be convenient to characteristics such as operation.
Description of drawings
Accompanying drawing 1 is the main TV structure sketch map of throat's dilator;
Accompanying drawing 2 is the left TV structure sketch map of throat's dilator.
Description of reference numerals: handle 1, press button 2, observation port 3, back-moving spring 4, fixedly distraction plate 5, movable distraction plate 6, light emitting diode 7, accumulator 8, trigger 9, hinge axis 10, ratch mechanism 11.
The specific embodiment
Explain below with reference to Figure of description throat of the present invention dilator being done.
A kind of throat of the present invention dilator, its structure is by handle 1, fixedly distraction plate 5, movable distraction plate 6, trigger 9, accumulator 8 and light emitting diode 7 are formed, fixedly distraction plate 5 is the top that circular arc is arranged on handle 1, circular arc activity distraction plate 6 is arranged on the fixedly below of distraction plate 5, the front portion of movable distraction plate 6 and the fixing anterior corresponding duckbill that is of distraction plate 5, handle 1 and fixedly be provided with observation port 3 between the distraction plate 5, the lower end of movable distraction plate 6 is connected with trigger 9 and is arranged on the below of observation port 3 by hinge axis 10, and ratch mechanism is arranged between handle and the trigger.
Accumulator 8 is arranged on the centre of handle 1, and accumulator 8 connects the press button 2 of handle 1 top and fixing distraction plate 5 forward light emitting diodes 7 by lead.
10 ones of the hinge axis of connection activity distraction plate 6 lower ends are provided with back-moving spring 4.
Be provided with ratch mechanism 11 between handle 1 and the trigger 9.
Embodiment:
A kind of throat of the present invention its processing and fabricating of dilator is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing, and handle, fixedly distraction plate and movable distraction plate can be used the engineering plastics processing and fabricating, and also available rustless steel is processed into.
Use also easily, during use, fixedly distraction plate and movable distraction plate after merging are extended throat, use the finger pull trigger gently, movable dilator just opens downwards, presses press button, and light emitting diode is lighted provides illumination.If operation on larynx, need expand throat for a long time, utilize ratch mechanism with trigger lock, operation finishes, and unclamps ratch mechanism, and movable distraction plate resets and fixedly struts plate closing in the effect of back-moving spring, just can take out from throat.
A kind of fauces expander of the present invention is compared with existing technology, have reasonable in design, simple in structure, be easy to Processing, little, easy to operate, the patient suffering of volume is little to be easy to the characteristics such as acceptance, thereby, have good popularization Use value.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
