Description

A kind of hand held oral section lighting searchlight

Technical field

The utility model relates to technical field of medical equipment, and in particular to a kind of hand held oral section lighting searchlight.

Background technique

The modern department of stomatology, which is mainly carried out, to be had correction, cold light whitening, esthetics reparation, manufactures meticulously all kinds of baking-ceramic tooths, part Removable denture, glue support, steel support, titanium alloy steel denture and all kinds of accurate attachmentes, immediate denture, complete denture.Carry out dental pulp simultaneously It disease, periodontosis, periapical disease, root canal treatment, glass ion, the dental filling of compound resin photocuring and the prevention of children's odontopathy and controls It treats.

In the numerous department of stomatology is carried out, without exception require to observe the oral cavity of patient, accommodating is doubted, right The oral cavity good illumination of progress can be more conducive to medical staff and observe oral cavity.

In the prior art, when medical staff carries out observing oral cavity treatment, in order to facilitate Dentist operation, patient is needed Atrium, and because the internal structure in oral cavity needs the time of patient's mouth open longer, therefore usually than more covert It is that extraneous tool is needed to be assisted opening in patient oral cavity, such operating process not only needs the help of medical staff, In addition higher tacit agreement degree is needed when carrying out illumination cooperation, therefore can exerted a certain influence to observation, will cause often The problem of inconvenient observation；So be badly in need of it is a kind of being capable of oral cavity to patient while the device expanding and illuminate.

Utility model content

In view of the above problems, the utility model provide it is a kind of it is easy to operate, can carry out simultaneously oral cavity expansion and The hand held oral section lighting searchlight of illumination.

The technical solution of the utility model are as follows: a kind of hand held oral section lighting searchlight mainly includes lever, opening Device, lighting device, bindiny mechanism and power supply device；The lever includes ontology and trigger guard, is provided with light source on the ontology and opens It closes, body interior is provided with ratchet mechanism and coil axis, trigger and rotation button, the ratchet mechanism packet are provided in the trigger guard It includes ratchet, active pawl, pawl set and spring, the ratchet, pawl set to be movably arranged in ontology, the active pawl passes through Pawl set can be connected on ratchet, and one end side of active pawl and ratchet contact surface is card interface, and side is sliding mouth, institute State return of the spring for active pawl；The coil axis with it is coaxially connected on the outside of ratchet；

The opener is arranged by the bindiny mechanism in ontology front end；The lighting device includes flexible pipe and lamp The front end of head, the flexible pipe is movably arranged on opener, and the front end of flexible pipe is arcuation, and the lamp cap is arranged in flexibility The rear end on the top of pipe, flexible pipe is wrapped on coil axis through ontology, and lamp cap is connect by flexible pipe with the power supply device；

The front end upper position of trigger guard is arranged in the rotation button, and rotation button is connect with active pawl；The light source switch It is connect with power supply device.

Further, the activity of ontology rear end upper position is provided through aid bar, and the inserting end of the aid bar is folder Gripping member accommodates the leakage end of bar to turn round handle, and on intrinsic flexible pipe, the rotation by turning round handle can for the clamping piece aid Pivoting flexible pipe causes the angle of lamp cap to be finely adjusted；It can be by the fine tuning to aid bar come the angle of rotary lamp holder, by light Directly treat look-out station, the more conducively observation of medical staff in source.

Further, bindiny mechanism downside is evenly arranged with multiple strips, and the flexible pipe can pass through the strip； Flexible pipe is fixed across strip, can efficiently avoid because flexible pipe is caused stretched by gravity factor Into, retreat when ineffective to result in illuminating effect bad.

Further, bindiny mechanism is connecting rod, and the latter half of upper surface of connecting rod is provided with rack gear, and the ontology upper end is set Be equipped with regulating device, the regulating device side is provided with knob, and regulating device is internally provided with gear, the rack gear with it is described Gear engagement, the knob are connect with gear, and bindiny mechanism can pass through knob rotating to carry-over bar with moving gear It advances and stretches in regulating device；Can by the cooperation of rack gear and regulating device come the putting in of control connecting mechanism, retreat It realizes that viewing angle, the visual field are more extensive, can be effectively prevented from when in use because of blocking and causing to see at the observation of device degree Examine inconvenience.

Further, opener includes supporting arc item and expansion plate, and there are two the supporting arc items, two supporting arc items point The both ends of the expansion plate are not set；Suitable for more crowds, different degrees of open can be carried out according to different crowds Mouthful.

Further, disposable gum cover is provided on supporting arc item；It is split after use can to efficiently avoid patient The complicated processes that mouthpart carries out disinfection efficiently avoid the cross-infection between patient, much cleaner.

The working principle of the utility model are as follows: before use, covering the replacement of disposable gum cover on supporting arc item, adjust Device makes bindiny mechanism to suitable position；Supporting arc item is placed on the lip of patient again, branch is then adjusted by expansion plate Support the opening that patient's corners of the mouth realizes patient；Then light source switch is pressed, flexible fine tuning is carried out to flexible pipe by trigger, is passed through Accommodating the fine tuning that bar carries out angle to flexible pipe realizes illumination to position to be seen；Flexible pipe is carried out by trigger it is flexible When fine tuning, flexible pipe is put in if pressing trigger, then only needing to rotate rotation button, then presses trigger again just Retreating for flexible pipe can be achieved.

Compared with prior art, the utility model is the utility model has the advantages that the utility model structure is simple, medical staff's hand-held device The expansion (opening), the illumination that carry out mouth to patient simultaneously can be achieved, the workload of medical staff can greatly be reduced；Together When, aid bar, the ratchet mechanism of the utility model setting can carry out the fine tuning in angles and positions to illuminating lamp holder, can incite somebody to action Illumination is directly directed at position to be seen, is more advantageous to medical staff and observes the oral cavity of patient, thus further effectively Ground improves the accuracy of observation result.
